  1. Chiropractic manipulation for the foot: Diversified chiropractic techniques.

    PubMed

    Lawrence, D J

    2001-05-01

    There has been increasing acceptance and development of manual methods in providing for the needs of patients with musculoskeletal dysfunction. Several professions have helped fuel this growth, including the chiropractic profession. To date, there has been only a small amount of collaboration between chiropractors and physical therapists. This paper provides a base foundation for one small part of general chiropractic practice, i.e. procedures used for manipulating the foot. Information is provided about the specific diagnostic procedures used by the chiropractic profession in assessing the joints and soft tissues of the foot, followed by descriptions of a number of chiropractic manipulative techniques drawn from the form of chiropractic in widest usage, Diversified technique. For each technique, information is provided on indications for use, patient position, therapist position, hand placements and procedure. In addition, a short discussion on the genesis of Diversified technique is provided.

    2009-10-01

    Spinal epidural hematoma is a rare but potentially devastating complication of spinal manipulation therapy. This is a case report of a healthy pregnant female who presented to the emergency department with a cervical epidural hematoma resulting from chiropractic spinal manipulation therapy that responded to conservative treatment rather than the more common route of surgical management.

  3. Medicolegal corner: Quadriplegia following chiropractic manipulation.

    PubMed

    Epstein, Nancy E; Forte Esq, Carol L

    2013-01-01

    A 45 year old male with multiple comorbidities presented to his internist with a 2 week history of right sided neck pain and tenderness, accompanied by tingling in the hand. The internists' neurological examination was normal, except for decreased range of motion of the right arm. He referred the patient to a chiropractor; he performed plain X rays which revealed mild spasm, but never ordered a magnetic resonance imaging study. The chiropractor manipulated the patient's neck on two successive days. By the morning of the third visit, the patient reported extreme pain and difficulty walking. Without performing a new neurological examination or obtaining an MR scan, the chiropractor again manipulated the patient's neck. He immediately became quadriplegic. Despite undergoing an emergency C5 C6 anterior cervical diskectomy/fusion to address a massive disc found on the MR scan (CT was negative), the patient remained quadriplegic (e.g., C4 sensory, C6 motor levels). A major point of negligence in this case was the failure of both the referring internist and chiropractor to order an MR of the cervical spine prior to the chiropractic manipulation. The internist claimed that there was no known report of permanent quadriplegia resulting from neck manipulation in any medical journal, article or book, or in any literature of any kind or on the internet and that the risk of this injury must be vanishingly small given the large numbers of manipulations performed annually. The total amount of the verdict was $14,596,000.00 the internist's liability was 5% ($759,181.65).

  4. Surgical treatment of cervical disc protrusion causing intracranial hypotension following chiropractic manipulation.

    Wilson, David; Steel, Timothy; Sutton, Ian

    2015-09-01

    We describe a woman with intracranial hypotension provoked by a combination of calcified disc protrusion and chiropractic manipulation who required surgical intervention for definitive treatment. Intracranial hypotension is a rare but increasingly well recognized cause of orthostatic headache that arises due to spinal cerebrospinal fluid leakage from meningeal diverticula or dural perforations.

  5. Inappropriate use of the title 'chiropractor' and term 'chiropractic manipulation' in the peer-reviewed biomedical literature

    Wenban, Adrian B

    2006-01-01

    Background The misuse of the title 'chiropractor' and term 'chiropractic manipulation', in relation to injury associated with cervical spine manipulation, have previously been reported in the peer-reviewed literature. The objectives of this study were to - 1) Prospectively monitor the peer-reviewed literature for papers reporting an association between chiropractic, or chiropractic manipulation, and injury; 2) Contact lead authors of papers that report such an association in order to determine the basis upon which the title 'chiropractor' and/or term 'chiropractic manipulation' was used; 3) Document the outcome of submission of letters to the editors of journals wherein the title 'chiropractor', and/or term 'chiropractic manipulation', had been misused and resulted in the over-reporting of chiropractic induced injury. Methods One electronic database (PubMed) was monitored prospectively, via monthly PubMed searches, during a 12 month period (June 2003 to May 2004). Once relevant papers were located, they were reviewed. If the qualifications and/or profession of the care provider/s were not apparent, an attempt was made to confirm them via direct e-mail communication with the principal researcher of each respective paper. A letter was then sent to the editor of each involved journal. Results A total of twenty four different cases, spread across six separate publications, were located via the monthly PubMed searches. All twenty four cases took place in one of two European countries. The six publications consisted of four case reports, each containing one patient, one case series, involving twenty relevant cases, and a secondary report that pertained to one of the four case reports. In each of the six publications the authors suggest the care provider was a chiropractor and that each patient received chiropractic manipulation of the cervical spine prior to developing symptoms suggestive of traumatic injury. In two of the four case reports contact with the principal

  6. Chiropractic: a critical evaluation.

    PubMed

    Ernst, Edzard

    2008-05-01

    Chiropractic was defined by D.D. Palmer as "a science of healing without drugs." About 60,000 chiropractors currently practice in North America, and, worldwide, billions are spent each year for their services. This article attempts to critically evaluate chiropractic. The specific topics include the history of chiropractic; the internal conflicts within the profession; the concepts of chiropractic, particularly those of subluxation and spinal manipulation; chiropractic practice and research; and the efficacy, safety, and cost of chiropractic. A narrative review of selected articles from the published chiropractic literature was performed. For the assessment of efficacy, safety, and cost, the evaluation relied on previously published systematic reviews. Chiropractic is rooted in mystical concepts. This led to an internal conflict within the chiropractic profession, which continues today. Currently, there are two types of chiropractors: those religiously adhering to the gospel of its founding fathers and those open to change. The core concepts of chiropractic, subluxation and spinal manipulation, are not based on sound science. Back and neck pain are the domains of chiropractic but many chiropractors treat conditions other than musculoskeletal problems. With the possible exception of back pain, chiropractic spinal manipulation has not been shown to be effective for any medical condition. Manipulation is associated with frequent mild adverse effects and with serious complications of unknown incidence. Its cost-effectiveness has not been demonstrated beyond reasonable doubt. The concepts of chiropractic are not based on solid science and its therapeutic value has not been demonstrated beyond reasonable doubt.

  7. Chiropractic spinal manipulation for low back pain of pregnancy: a retrospective case series.

    PubMed

    Lisi, Anthony J

    2006-01-01

    Low back pain is a common complaint in pregnancy, with a reported prevalence of 57% to 69% and incidence of 61%. Although such pain can result in significant disability, it has been shown that as few as 32% of women report symptoms to their prenatal provider, and only 25% of providers recommend treatment. Chiropractors sometimes manage low back pain in pregnant women; however, scarce data exist regarding such treatment. This retrospective case series was undertaken to describe the results of a group of pregnant women with low back pain who underwent chiropractic treatment including spinal manipulation. Seventeen cases met all inclusion criteria. The overall group average Numerical Rating Scale pain score decreased from 5.9 (range 2-10) at initial presentation to 1.5 (range 0-5) at termination of care. Sixteen of 17 (94.1%) cases demonstrated clinically important improvement. The average time to initial clinically important pain relief was 4.5 (range 0-13) days after initial presentation, and the average number of visits undergone up to that point was 1.8 (range 1-5). No adverse effects were reported in any of the 17 cases. The results suggest that chiropractic treatment was safe in these cases and support the hypothesis that it may be effective for reducing pain intensity.

    2016-01-01

    Background Spinal manipulation therapy (SMT) is a popular though controversial practice. The debates surrounding efficacy and risk of SMT are only partially evident in popular discourse. Objective This study aims to investigate the presence of critiques and debates surrounding efficacy and risk of SMT on the social media platform Twitter. The study examines whether there is presence of debate and whether critical information is being widely disseminated. Methods An initial corpus of 31,339 tweets was compiled through Twitter’s Search Application Programming Interface using the query terms “chiropractic,” “chiropractor,” and “spinal manipulation therapy.” Tweets were collected for the month of December 2015. Post removal of tweets made by bots and spam, the corpus totaled 20,695 tweets, of which a sample (n=1267) was analyzed for skeptical or critical tweets. Additional criteria were also assessed. Results There were 34 tweets explicitly containing skepticism or critique of SMT, representing 2.68% of the sample (n=1267). As such, there is a presence of 2.68% of tweets in the total corpus, 95% CI 0-6.58% displaying explicitly skeptical or critical perspectives of SMT. In addition, there are numerous tweets highlighting the health benefits of SMT for health issues such as attention deficit hyperactivity disorder (ADHD), immune system, and blood pressure that receive scant critical attention. The presence of tweets in the corpus highlighting the risks of “stroke” and “vertebral artery dissection” is also minute (0.1%). Conclusions In the abundance of tweets substantiating and promoting chiropractic and SMT as sound health practices and valuable business endeavors, the debates surrounding the efficacy and risks of SMT on Twitter are almost completely absent. Although there are some critical voices of SMT proving to be influential, issues persist regarding how widely this information is being disseminated. PMID:27637456

  9. Treatment of a patient with posterior cortical atrophy (PCA) with chiropractic manipulation and Dynamic Neuromuscular Stabilization (DNS): A case report

    PubMed Central

    Francio, Vinicius T.; Boesch, Ron; Tunning, Michael

    2015-01-01

    Objective: Posterior cortical atrophy (PCA) is a rare progressive neurodegenerative syndrome which unusual symptoms include deficits of balance, bodily orientation, chronic pain syndrome and dysfunctional motor patterns. Current research provides minimal guidance on support, education and recommended evidence-based patient care. This case reports the utilization of chiropractic spinal manipulation, dynamic neuromuscular stabilization (DNS), and other adjunctive procedures along with medical treatment of PCA. Clinical features: A 54-year-old male presented to a chiropractic clinic with non-specific back pain associated with visual disturbances, slight memory loss, and inappropriate cognitive motor control. After physical examination, brain MRI and PET scan, the diagnosis of PCA was recognized. Intervention and Outcome: Chiropractic spinal manipulation and dynamic neuromuscular stabilization were utilized as adjunctive care to conservative pharmacological treatment of PCA. Outcome measurements showed a 60% improvement in the patient’s perception of health with restored functional neuromuscular pattern, improvements in locomotion, posture, pain control, mood, tolerance to activities of daily living (ADLs) and overall satisfactory progress in quality of life. Yet, no changes on memory loss progression, visual space orientation, and speech were observed. Conclusion: PCA is a progressive and debilitating condition. Because of poor awareness of PCA by physicians, patients usually receive incomplete care. Additional efforts must be centered on the musculoskeletal features of PCA, aiming enhancement in quality of life and functional improvements (FI). Adjunctive rehabilitative treatment is considered essential for individuals with cognitive and motor disturbances, and manual medicine procedures may be consider a viable option. PMID:25729084

    1995-01-01

    Biomedical literature retrieval, both indexed and non-indexed, with respect to the application of manipulative therapy with therapeutic intent and pediatric health conditions (ages 0 to 17 years) yielded 66 discrete documents which met specified inclusion and exclusion criteria. There was one experimental study (RCT’s), 3 observational (cohort, case control) studies and 62 descriptive studies (case series, case reports, surveys, literature reviews). An independent rating panel determined consistency with a modified quality of evidence scale adopted from procedure ratings system 1 of Clinical Guidelines for Chiropractic Practice in Canada. Results indicate minimal Class 1 and Class 2 and some Class 3 evidence for a variety of pediatric conditions utilizing the application of manipulation with therapeutic intent.

  11. Cervical Epidural Hematoma after Chiropractic Spinal Manipulation Therapy in a Patient with an Undiagnosed Cervical Spinal Arteriovenous Malformation

    PubMed Central

    Huang, Meng; Barber, Sean M; Moisi, Marc; Powell, Suzanne; Rivera, Andreana; Rose, James

    2015-01-01

    Spinal epidural hematoma (SEH) occurring after chiropractic spinal manipulation therapy (CSMT) is a rare clinical phenomenon. Our case is unique because the patient had an undiagnosed cervical spinal arteriovenous malformation (AVM) discovered on pathological analysis of the evacuated hematoma. Although the spinal manipulation likely contributed to the rupture of the AVM, there was no radiographic evidence of the use of excessive force, which was seen in another reported case. As such, patients with a known AVM who have not undergone surgical intervention should be cautioned against symptomatic treatment with CSMT, even if performed properly. Regardless of etiology, SEH is a surgical emergency and its favorable neurological recovery correlates inversely with time to surgical evacuation. PMID:26430581

    2012-01-01

    Objective The purpose of this report is to describe the response of a geriatric patient with low back pain and a history of leukemia, multiple compression fractures, osteoporosis, and degenerative joint disease using Activator chiropractic technique. Case Report An 83-year-old man who is the primary caretaker for his disabled wife had low back pain after lifting her into a truck. The patient had a history of leukemia, multiple compression fractures, osteoporosis, and degenerative joint disease. His Revised Oswestry Low Back Pain Disability Questionnaire was 26%, with a 10/10 pain rating at its worst on the Numeric Pain Scale. The patient presented with a left head tilt, right high shoulder, and right high ilium with anterior translation and flexion of the torso and spasm and tenderness from the lower thoracic spine to lumbar spine. Intervention and Outcome The patient was cared for using Activator Methods protocol. After 8 treatments, the patient was stable and remained stable for 4 months without spasm or tenderness in his spine. His Revised Oswestry score dropped to 6%, with a 4/10 Numeric Pain Scale pain rating when at its worst; and the patient reported being able to take care of his wife. Conclusion The findings of this case suggest that Activator-assisted spinal manipulative therapy had a positive effect on low back pain and function in an elderly patient with a complex clinical history.

    Introduction Migraine affects 15% of the population, and has substantial health and socioeconomic costs. Pharmacological management is first-line treatment. However, acute and/or prophylactic medicine might not be tolerated due to side effects or contraindications. Thus, we aim to assess the efficacy of chiropractic spinal manipulative therapy (CSMT) for migraineurs in a single-blinded placebo-controlled randomised clinical trial (RCT). Method and analysis According to the power calculations, 90 participants are needed in the RCT. Participants will be randomised into one of three groups: CSMT, placebo (sham manipulation) and control (usual non-manual management). The RCT consists of three stages: 1 month run-in, 3 months intervention and follow-up analyses at the end of the intervention and 3, 6 and 12 months. The primary end point is migraine frequency, while migraine duration, migraine intensity, headache index (frequency x duration x intensity) and medicine consumption are secondary end points. Primary analysis will assess a change in migraine frequency from baseline to the end of the intervention and follow-up, where the groups CSMT and placebo and CSMT and control will be compared. Owing to two group comparisons, p values below 0.025 will be considered statistically significant. For all secondary end points and analyses, a p value below 0.05 will be used. The results will be presented with the corresponding p values and 95% CIs. Ethics and dissemination The RCT will follow the clinical trial guidelines from the International Headache Society. The Norwegian Regional Committee for Medical Research Ethics and the Norwegian Social Science Data Services have approved the project. Procedure will be conducted according to the declaration of Helsinki. The results will be published at scientific meetings and in peer-reviewed journals. Trial registration number NCT01741714.

    Gotlib, Allan; Rupert, Ron

    2008-01-01

    Objective Our purpose was to review the biomedical literature from January 2004 to June 2007 inclusive to determine the extent of new evidence related to the therapeutic application of manipulation for pediatric health conditions. This updates a previous systematic review published in 2005. No critical appraisal of the evidence is undertaken. Data Sources We searched both the indexed and non-indexed biomedical manual therapy literature. This included PubMed, MANTIS, CINAHL, ICL, as well as reference tracking. Other resources included the Cochrane Library, CCOHTA, PEDro, WHO ICTRP, AMED, EMBASE and AHRQ databases, as well as research conferences and symposium proceedings. Results The search identified 1275 citations of which 57 discrete citations met the eligibility criteria determined by three reviewers who then determined by consensus, each citation's appropriate level on the strength of evidence scale. The new evidence from the relevant time period was 1 systematic review, 1 RCT, 2 observational studies, 36 descriptive case studies and 17 conference abstracts. When this additional evidence is combined with the previous systematic review undertaken up to 2003, there are now in total, 2 systematic reviews, 10 RCT's, 3 observational studies, 177 descriptive studies, and 31 conference abstracts defining this body of knowledge. Summary There has been no substantive shift in this body of knowledge during the past 3 1/2 years. The health claims made by chiropractors with respect to the application of manipulation as a health care intervention for pediatric health conditions continue to be supported by only low levels of scientific evidence. Chiropractors continue to treat a wide variety of pediatric health conditions. The evidence rests primarily with clinical experience, descriptive case studies and very few observational and experimental studies. The health interests of pediatric patients would be advanced if more rigorous scientific inquiry was undertaken to examine

    Cox, J M; Shreiner, S

    1984-03-01

    A chiropractic multicenter observational pilot study to compile statistics on the examination procedures, diagnosis, types of treatments rendered, results of treatment, number of days of care, and number of treatments required to arrive at a 50% and a maximum clinical improvement was collected on 576 patients with low back and/or leg pain. The purpose was to determine the congenital and developmental changes in patients with low back and/or leg pain, the combinations of such anomalies, the accuracy of orthodox diagnostic tests in assessing low back pain, ergonomic factors affecting onset and, ultimately, the specific difficulty factors encountered in treating the various conditions seen in the average chiropractor's office. For all conditions treated, the average number of days to attain maximum improvement was 43 and the number of visits 19. It was concluded that this study provided useful data for assessment of routine chiropractic office based diagnosis and treatment of related conditions; however, further controlled studies are necessary for validation of specific parameters.

    2016-04-01

    We assessed the attitudes of Canadian obstetricians toward chiropractic with a 38-item cross-sectional survey. Ninety-one obstetricians completed the survey, for a response rate of 14% (91 of 659). Overall, 30% of respondents held positive views toward chiropractic, 37% were neutral, and 33% reported negative views. Most (77%) reported that chiropractic care was effective for some musculoskeletal complaints, but 74% disagreed that chiropractic had a role in treatment of non-musculoskeletal conditions. Forty percent of respondents referred at least some patients for chiropractic care each year, and 56% were interested in learning more about chiropractic care. Written comments from respondents revealed concerns regarding safety of spinal manipulation and variability among chiropractors. Canadian obstetricians' attitudes toward chiropractic are diverse and referrals to chiropractic care for their patients who suffer from pregnancy-related low back pain are limited. Improved interprofessional relations may help optimize care of pregnant patients suffering from low back pain.

  1. Pediatric Chiropractic Care: The Subluxation Question And Referral Risk.

    PubMed

    Homola, Samuel

    2016-02-01

    Chiropractors commonly treat children for a variety of ailments by manipulating the spine to correct a 'vertebral subluxation' or a 'vertebral subluxation complex' alleged to be a cause of disease. Such treatment might begin soon after a child is born. Both major American chiropractic associations - the International Chiropractic Association and the American Chiropractic Association - support chiropractic care for children, which includes subluxation correction as a treatment or preventive measure. I do not know of any credible evidence to support chiropractic subluxation theory. Any attempt to manipulate the immature, cartilaginous spine of a neonate or a small child to correct a putative chiropractic subluxation should be regarded as dangerous and unnecessary. Referral of a child to a chiropractor for such treatment should not be considered lest a bad outcome harms the child or leads to a charge of negligence or malpractice.

    Abstract Objective The objective of this study was to characterize the practice of pediatric chiropractic. Design The study design was a cross-sectional descriptive survey. Settings/location The settings were private practices throughout the United States, Canada, and Europe. Participants The participants were 548 chiropractors, the majority of whom are practicing in the United States, Canada, and Europe. Main outcome measures Practitioner demographics (i.e., gender, years in practice, and chiropractic alma mater), practice characteristics (i.e., patient visits per week, practice income reimbursement), and chiropractic technique were surveyed. The practitioners were also asked to indicate common indicators for pediatric presentation, their practice activities (i.e., use of herbal remedies, exercise and rehabilitation, prayer healing, etc.), and referral patterns. Results A majority of the responders were female with an average practice experience of 8 years. They attended an average of 133 patient visits per week, with 21% devoted to the care of children (<18 years of age). Practice income was derived primarily from out-of-pocket reimbursement with charges of an average of $127 and $42 for the first and subsequent visits, respectively. These visits were reimbursed to address common conditions of childhood (i.e., asthma, ear infections, etc.). Approach to patient care was spinal manipulative therapy (SMT) augmented with herbal remedies, exercises, rehabilitation, and so on. Wellness care also figured prominently as a motivator for chiropractic care. Fifty-eight percent (58%) indicated an established relationship with an osteopathic or medical physician. Eighty percent (80%) of the responders indicated referring patients to medical practitioners while only 29% indicated receiving a referral from a medical/osteopathic physician. Conclusions The chiropractic care of children is a significant aspect of the practice of chiropractic. Further research is warranted to

    The purpose of this paper is to review some of the applications of laser therapy and its reported effects on tissue healing, pain relief and other effects. Several musculoskeletal and low back pain studies are highlighted to show the efficacy of laser therapy and its' applicability as an adjunct to chiropractic treatment. Information is also presented which highlights the necessary information the clinician should be aware of in order to develop specific protocols for musculoskeletal pathologies. The parameters, which are now available on lasers, include power, frequency, duty cycle and cadence. When these are manipulated, different effects are achieved on tissues, which may enhance chiropractic treatment. Imagesp34-a

    Musculoskeletal disorders remain a common disability suffered by Australians, but the question of who should treat them remains a contentious issue as the first centenary of the original chiropractic adjustment approaches. This paper, part of a longitudinal study of the role of chiropractic in the Australian health system, analyses this ongoing debate. Recent events are analysed here in this commentary on the politics of health care in this field. These include meta-analysis to evaluate the effectiveness of spinal manipulation for the treatment of lower back pain, recent legal action in the United States, and the recent epistle against Australian chiropractors published by the Australian Medical Association.

  5. Chiropractic approach to the management of children

    PubMed Central

    2010-01-01

    Background Chiropractic (Greek: done by hand) is a health care profession concerned with the diagnosis, treatment and prevention of disorders of the neuromusculoskeletal system and the effects of these disorders on general health. There is an emphasis on manual techniques, including joint adjustment and/or manipulation, with a particular focus on joint subluxation (World Health Organization 2005) or mechanical lesion and restoring function. The chiropractor's role in wellness care, prevention and treatment of injury or illness is based on education in anatomy and physiology, nutrition, exercise and healthy lifestyle counseling as well as referral to other health practitioners. Depending on education, geographic location, scope of practice, as well as consumer preference, chiropractors may assume the role of primary care for families who are pursuing a more natural and holistic approach to health care for their families. Objective To present a perspective on current management of the paediatric patient by members of the chiropractic profession and to make recommendations as to how the profession can safely and effectively manage the paediatric patient. Discussion The chiropractic profession holds the responsibility of ethical and safe practice and requires the cultivation and mastery of both an academic foundation and clinical expertise that distinguishes chiropractic from other disciplines. Research into the effectiveness of chiropractic care for paediatric patients has lagged behind that of adult care, but this is being addressed through educational programs where research is now being incorporated into academic tracks to attain advanced chiropractic degrees. Conclusion Studies in the United States show that over the last several decades, chiropractors are the most common complementary and alternative medicine providers visited by children and adolescents. Chiropractors continue to seek integration with other healthcare providers to provide the most appropriate

    2011-05-01

    To promote an independent and critical evaluation of 11 randomised clinical trials (RCTs) of chiropractic funded by the National Centre for Complementary and Alternative Medicine (NCCAM). Electronic searches were conducted to identify all relevant RCTs. Key data were extracted and the risk of bias of each study was determined. Ten RCTs were included, mostly related to chiropractic spinal manipulation for musculoskeletal problems. Their quality was frequently questionable. Several RCTs failed to report adverse effects and the majority was not described in sufficient detail to allow replication. The criticism repeatedly aimed at NCCAM seems justified, as far as their RCTs of chiropractic is concerned. It seems questionable whether such research is worthwhile.

    Objective: Surveys for the National Board of Chiropractic Examiners indicate that diversified chiropractic technique is the most commonly used chiropractic manipulation method. The study objective was to investigate the influences of our diversified core technique curriculum, a technique survey course, and extracurricular technique activities on students' future practice technique preferences. Methods: We conducted an anonymous, voluntary survey of 1st, 2nd, and 3rd year chiropractic students at our institution. Surveys were pretested for face validity, and data were analyzed using descriptive and inferential statistics. Results: We had 164 students (78% response rate) participate in the survey. Diversified was the most preferred technique for future practice by students, and more than half who completed the chiropractic technique survey course reported changing their future practice technique choice as a result. The students surveyed agreed that the chiropractic technique curriculum and their experiences with chiropractic practitioners were the two greatest bases for their current practice technique preference, and that their participation in extracurricular technique clubs and seminars was less influential. Conclusions: Students appear to have the same practice technique preferences as practicing chiropractors. The chiropractic technique curriculum and the students' experience with chiropractic practitioners seem to have the greatest influence on their choice of chiropractic technique for future practice. Extracurricular activities, including technique clubs and seminars, although well attended, showed a lesser influence on students' practice technique preferences. PMID:26655282

    2014-01-01

    Objective The purpose of this case report is to describe a patient who presented to a chiropractic physician for evaluation and treatment of neck pain and headache. Clinical features A 45-year-old otherwise healthy female presented for evaluation and treatment of neck pain and headache. Within minutes, non-specific musculoskeletal symptoms progressed to neurological deficits, including limb ataxia and cognitive disturbances. Suspicion was raised for cerebrovascular ischemia and emergent referral was initiated. Intervention and outcome Paramedics were immediately summoned and the patient was transported to a local hospital with a working diagnosis of acute cerebrovascular ischemia. Multiplanar computed tomographic and magnetic resonance imaging with contrast revealed vertebral artery dissection of the V2 segment in the right vertebral artery. Anticoagulation therapy was administered and the patient was discharged without complications after 5 days in the hospital. Conclusion This case highlights the potential for patients with vertebral artery dissection to present with nonspecific musculoskeletal complaints. Neurological symptoms may not manifest initially, but their sudden onset indicates the possibility of an ischemic cerebrovascular event. We suggest that early recognition and emergent referral for this patient avoided potential exacerbation of an evolving pre-existing condition and resulted in timely anticoagulation treatment.

  10. The role of chiropractic care in older adults

    PubMed Central

    2012-01-01

    There are a rising number of older adults; in the US alone nearly 20% of the population will be 65 or older by 2030. Chiropractic is one of the most frequently utilized types of complementary and alternative care by older adults, used by an estimated 5% of older adults in the U.S. annually. Chiropractic care involves many different types of interventions, including preventive strategies. This commentary by experts in the field of geriatrics, discusses the evidence for the use of spinal manipulative therapy, acupuncture, nutritional counseling and fall prevention strategies as delivered by doctors of chiropractic. Given the utilization of chiropractic services by the older adult, it is imperative that providers be familiar with the evidence for and the prudent use of different management strategies for older adults.

  12. Chiropractic: history and overview of theories and methods.

    PubMed

    Homola, Samuel

    2006-03-01

    Chiropractic is one of the most controversial and poorly defined healthcare professions with recognition and licensure in the United States. Chiropractic was started by D. D. Palmer, a magnetic healer who formulated the vertebral subluxation theory. The profession was developed by his son, B. J. Palmer. Although the definition of chiropractic as a method of correcting vertebral subluxations to restore and maintain health is questionable, spinal manipulation is of value in the treatment of some types of back pain. The chiropractic profession is still based on the vertebral subluxation theory, and has the confusing image of a back specialty capable of treating a broad scope of health problems. Despite opposition to use of spinal manipulation as a method of treating a broad scope of health problems (as opposed to the generally accepted use of manipulation in the treatment of back pain), chiropractors seek support as primary care providers in alternative medicine. It is essential to understand the theories, philosophies, and methods of chiropractic for an objective evaluation.

    Sports chiropractic within Australia has a chequered historical background of unorthodox individualistic displays of egocentric treatment approaches that emphasise specific technique preference and individual prowess rather than standardised evidence based management. This situation has changed in recent years with the acceptance of many within sports chiropractic to operate under an evidence informed banner and to embrace a research culture. Despite recent developments within the sports chiropractic movement, the profession is still plagued by a minority of practitioners continuing to espouse certain marginal and outlandish technique systems that beleaguer the mainstream core of sports chiropractic as a cohesive and homogeneous group. Modern chiropractic management is frequently multimodal in nature and incorporates components of passive and active care. Such management typically incorporates spinal and peripheral manipulation, mobilisation, soft tissue techniques, rehabilitation and therapeutic exercises. Externally, sports chiropractic has faced hurdles too, with a lack of recognition and acceptance by organized and orthodox sports medical groups. Whilst some arguments against the inclusion of chiropractic may be legitimate due to its historical baggage, much of the argument appears to be anti-competitive, insecure and driven by a closed-shop mentality.sequently, chiropractic as a profession still remains a pariah to the organised sports medicine world. Add to this an uncertain continuing education system, a lack of protection for the title 'sports chiropractor', a lack of a recognized specialist status and a lack of support from traditional chiropractic, the challenges for the growth and acceptance of the sports chiropractor are considerable. This article outlines the historical and current challenges, both internal and external, faced by sports chiropractic within Australia and proposes positive changes that will assist in recognition and inclusion of sports

  14. Legislative approaches to the regulation of the chiropractic profession.

    Chapman-Smith, D A

    1997-01-01

    Traditional and complementary health care services have a growing and significant role in both developed and developing countries. In the United Kingdom the British Medical Association (BMA) has identified five complementary approaches to health care that should now be regarded as "discrete clinical disciplines" because they have "established foundations of training and have the potential for greatest use alongside orthodox medical care". These are acupuncture, chiropractic, herbalism, homeopathy and osteopathy. The BMA recommended that there should be legislation to regulate these disciplines and the Chiropractors' Act enacted in the U.K in 1994. The chiropractic profession was founded in the United States in 1895, and the practice of chiropractic has been regulated in the United States and Canada since the 1920s, in Australia since the late 1940s, in New Zealand and South Africa since the 1960s, and more recently in Asia, Europe, Latin America and elsewhere. Figure 1 lists the countries which currently recognize and regulate the chiropractic profession. Many countries, such as Japan with approximately 10,000 chiropractors with different levels of education, and Trinidad & Tobago with 5 chiropractors who are graduates of accredited chiropractic colleges in North America, are considering legislation. Croatia, with 3 chiropractors, is preparing legislation. Cyprus, with 6 chiropractors, has legislation. Even in countries such as these, where the profession is small, there are compelling public interest arguments for regulation. This is especially true in the 1990s. One reason is the growing incentive for lay healers and others without formal training to use the title "chiropractor" as chiropractic practice gains increasing acceptance. The majority of chiropractic practice involves patients with non- specific or mechanical back and neck pain. The chiropractic approach to management, which includes spinal adjustment or manipulation, other physical treatments, postural

    The necessity for an animal model in chiropractic research is considered and a short review of previous experimentation of manipulation on animals is presented. The guinea pig is proposed as a suitable animal model, and research into its suitability is presented. Analysis includes the animal’s physical characteristics, the choice of anesthetic and parametric and roentgenographic evaluation. A device for supporting the anesthetized animal during standard and motion roentgenographic examination is described. We conclude that this animal model fulfills the requirements necessary for successful investigation in chiropractic research, and the need for such investigation is emphasized.

    The purpose of this collaborative summary is to document current chiropractic involvement in the public health movement, reflect on social ecological levels of influence as a profession, and summarize the relationship of chiropractic to the current public health topics of: safety, health issues through the lifespan, and effective participation in community health issues. The questions that are addressed include: Is spinal manipulative therapy for neck and low-back pain a public health problem? What is the role of chiropractic care in prevention or reduction of musculoskeletal injuries in children? What ways can doctors of chiropractic stay updated on evidence-based information about vaccines and immunization throughout the lifespan? Can smoking cessation be a prevention strategy for back pain? Does chiropractic have relevance within the VA Health Care System for chronic pain and comorbid disorders? How can chiropractic use cognitive behavioral therapy to address chronic low back pain as a public health problem? What opportunities exist for doctors of chiropractic to more effectively serve the aging population? What is the role of ethics and the contribution of the chiropractic profession to public health? What public health roles can chiropractic interns perform for underserved communities in a collaborative environment? Can the chiropractic profession contribute to community health? What opportunities do doctors of chiropractic have to be involved in health care reform in the areas of prevention and public health? What role do citizen-doctors of chiropractic have in organizing community action on health-related matters? How can our future chiropractic graduates become socially responsible agents of change?

    The practice of chiropractic was for many years regulated by "The Quack Act" in Norway, and the numbers of chiropractors decreased year by year. They are now authorized health care practitioners with academic training; most Norwegian students attending courses in chiropractic or clinical biomechanics go to European universities. An international council ensures reciprocity and a quality assured academic programme in all recognized colleges of chiropractic. Recent research have broadened our understanding of the biomechanical interrelationship between the nervous system, the musculature and the skeletal articulations. In the early 1990s, several studies documented favourable effect of chiropractic treatment of low back disorders. These studies are now substantiated by new studies, especially concerning cost-effectiveness. Several reports also give evidence that chiropractic manipulation is beneficial especially in combination with light exercise. There are conflicting results concerning the efficacy of varying types of exercise programmes. Patients may benefit from increased cooperation between medical doctors and chiropractors. Most acute low back syndromes should be assessed by the chiropractor in order to prevent chronic illness.

    2009-01-01

    There is a need to further our understanding of the neurophysiological effects of chiropractic spinal manipulation on brain activity as it pertains to both musculoskeletal and non-musculoskeletal complaints. This paper aims to provide a basic overview of the most commonly utilised techniques in the neurosciences for functional imaging the brain (positron emission tomography, single-photon emission computerised tomography, functional magnetic resonance imaging, electroencephalography, and magnetoencephalography), and discuss their applicability in future chiropractic research. Functional neuroimaging modalities are used in a wide range of different research and clinical settings, and are powerful tools in the investigation of neuronal activity in the human brain. There are many potential applications for functional neuroimaging in future chiropractic research, but there are some feasibility issues, mainly pertaining to access and funding. We strongly encourage the use of functional neuroimaging in future investigations of the effects of chiropractic spinal manipulation on brain function. PMID:19421353

    Objective: One objective of chiropractic education is to cultivate clinical confidence in novice practitioners. The purpose of this qualitative study was to describe how participation in a short-term international service learning experience changed perceptions of clinical confidence in senior chiropractic students. Methods: Seventeen senior chiropractic students participated in 4 moderated focus group sessions within 4 months after a clinical educational opportunity held in international settings. Participants answered standard questions on how this educational experience may have changed their clinical confidence. Two investigators performed qualitative thematic analysis of the verbatim transcripts to identify core concepts and supporting themes. Results: The core concept was transformation from an unsure student to a confident doctor. The service learning experience allowed students to deliver chiropractic treatment to patients in a real-world setting, engage in frequent repetitions of technical skills, perform clinical decision-making and care coordination, and communicate with patients and other health professionals. Students described increased clinical confidence in 9 competency areas organized within 3 domains: (1) chiropractic competencies including observation, palpation, and manipulation; (2) clinical competencies including problem solving, clinic flow, and decision-making; and (3) communication competencies, including patient communication, interprofessional communication, and doctor–patient relationship. Students recommended that future service learning programs include debriefing sessions similar to the experience offered by these focus groups to enhance student learning. Conclusion: Senior chiropractic students who participated in an international service learning program gained confidence and valuable practical experience in integrating their chiropractic, clinical, and communication skills for their future practices.

    Chiropractic education in the northwestern United States has its origins in the Marsh School & Cure in 1904. Most of the early schools were located in Portland, Oregon, including the D.D. Palmer College of Chiropractic (1908-1910), and several of these had merged by 1912 or 1913 to form the Pacific Chiropractic College, forerunner of today's Western States College. The latter was organized as a non-profit institution during the Great Depression, and struggled not only to survive but to create a higher standard. The early broad-scope of chiropractic training in the state probably encouraged the liberal scope of practice enjoyed in Oregon to this day.

    Objective The purpose of this case report is to describe the chiropractic management of an 8-year-old girl with nonorganic, primary nocturnal enuresis. Clinical Features An 8-year-old female patient presented to a chiropractic clinic with persistent nighttime bedwetting. The patient experienced enuresis, on average, 7 nights per week. The patient presented with no other comorbidities or complaints, such as low back or pelvic pain. Intervention and Outcomes Chiropractic treatment included high-velocity, low-amplitude manipulation of the left sacroiliac joint over 3 visits. Follow-up at 3 months revealed only 3 subsequent episodes of nocturnal enuresis. Conclusion This patient reported the resolution of nonorganic, primary nocturnal enuresis after receiving a series of side-posture chiropractic manipulations of the left sacroiliac joint.

    Geriatric care has assumed a more dominant position in the health care delivery system. This article discusses the results of a literature search on geriatric chiropractic care with the ultimate goal of promoting a“best practice” approach. Fifty nine articles were found that discussed geriatric chiropractic education (N = 3), demographic and epidemiological studies (N = 9), case studies (N = 25), clinical trials (N = 4) and clinical guidelines (N = 18). The literature revealed that chiropractic pedagogy has recognized the importance of geriatric education, and epidemiological studies reported an increase in utilization rates of chiropractic care by older persons, along with greater acceptance within the medical community. Most older persons sought out chiropractic care for neuromusculoskeletal (NMS) conditions, with several studies reporting the successful resolution of these conditions with spinal manipulative therapy as well as an eclectic group of other treatment interventions. Many older persons enter a maintenance care program, which they believe to be important to their health. Although the results of this article are encouraging, it underscores the need for continued research, especially in the areas of chiropractic maintenance care and the management of non-NMS conditions.

    Background: The intensive training associated with health care education has been suggested to have unintended negative consequences on students’ mental or emotional health that may interfere with the development of qualities deemed essential for proficient health care professionals. This longitudinal study examined the prevalence and severity of depressive symptoms among students at a chiropractic educational institution. Methods: Chiropractic students at all levels of training were surveyed at Canadian Memorial Chiropractic College during the academic years of 2000/2001, 2001/2002, and 2002/2003. The measurement tool employed was the Beck Depression Inventory, 2nd edition (BDI-II). Previously established BDI-II cutoff scores were used to assess the severity of reported depression symptoms, and these were compared by sex and year of training. Results: The survey was completed by 1303 students (70%) over the 3 years of the study. The prevalence of depressive symptoms was nearly 25%, with 13.7% of respondents indicating a rating of mild depression, 7.1% indicating moderate depressive symptoms, and 2.8% indicating severe symptoms. Significant differences were found between years of training, with 2nd-year students having the highest prevalence of depressive symptoms, and sex, with females having a higher rate of symptoms. Conclusions: Chiropractic students surveyed at Canadian Memorial Chiropractic College had high rates of depression similar to those measured in other health care profession students. Chiropractic educational institutions should be aware of this situation and are encouraged to emphasize students’ awareness of their own personal health and well-being and their access to appropriate care, in addition to the same concerns for their future patients.

    Alcantara, Joel; Cossette, Martine

    2009-11-01

    The absence of hormone fluctuations and/or the analgesic effects of increased beta-endorphins are thought to confer improvements in headache symptoms during pregnancy. However, for a number of pregnant patients, they continue to suffer or have worsening headache symptoms. The use of pharmacotherapy for palliative care is a concern for both the mother and the developing fetus and alternative/complementary care options are sought. We present a 24-year-old gravid female with chronic migraine headaches since age 12years. Previous unsuccessful care included osteopathy, physical therapy, massage and medication. Non-steroidal anti-inflammatory medication with codeine provided minor and temporary relief. Chiropractic care involving spinal manipulative therapy (SMT) and adjunctive therapies resulted in symptom improvement and independence from medication. This document provides supporting evidence on the safety and possible effectiveness of chiropractic care for patients with headaches during pregnancy.

    Background There is limited outcome measure support for chiropractic manipulative therapy in the management of ankylosing spondylitis. An improvement in specific indices for both function and disease activity during chiropractic therapy for ankylosing spondylitis has not previously been reported. Objective To measure changes in function and disease activity in a patient with ankylosing spondylitis during a course of chiropractic therapy. The clinical management of ankylosing spondylitis, including chiropractic manipulative therapy and the implications of this case study are discussed. Clinical Features A 34-year-old male with a 10 year diagnosis of ankylosing spondylitis sought chiropractic treatment for spinal pain and stiffness. His advanced radiographic signs included an increased atlantodental interspace and cervical vertebral ankylosis. Intervention and outcome The Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), finger-tip-to-floor distance and chest expansion were assessed during an 18 week course of chiropractic spinal manipulation and mobilization therapy. There was a 90% improvement in the disease activity index and an 85% improvement in the functional index from the pre-treatment baseline, as measured by the BASDAI and BASFI respectively. Spinal flexibility and chest expansion also improved. Conclusion To the authors knowledge this is the first study to incorporate ankylosing spondylitis specific indices, for both disease activity and function, to objectively support the use of chiropractic manipulative therapy in the management of ankylosing spondylitis. More intensive research is suggested. PMID:17549197

    The following case describes a 68 year-old woman with a 7½ year history of worsening head and neck pain diagnosed as trigeminal neuralgia following surgical resection of a brain tumor. After years of unsuccessful management with medication and physical therapies, a therapeutic trial of chiropractic was carried out. Chiropractic care included ultrasound, manual therapies (manipulation and mobilization), soft tissue therapies, and home stretching exercises. After an initial treatment period followed by 18 months of supportive care the patient reported satisfactory improvement. It became evident that there were at least three sources of her symptoms: mechanical and/or degenerative neck pain, temporomandibular joint syndrome, and trigeminal neuralgia. While never completely pain-free, the patient continued to report that her pains reduced to minimal at times. At the most recent follow-up, the pain had not returned to pre-treatment intractable levels. This case study demonstrates the importance of diagnosing and treating multiple sources of pain and the positive role chiropractic care can have in the management of patients with these clinical conditions. The potential for convergence of sensory input from the upper three cervical segments and the trigeminal nerve via the trigeminocervical nucleus is discussed. PMID:20808617

    The purpose of this study was to provide a narrative review of the literature of studies describing the management of disorders of the gastro-intestinal (GI) tract using ‘chiropractic therapy’ broadly defined here as spinal manipulation therapy, mobilizations, soft tissue therapy, modalities and stretches. Search limiters include access to full text studies published between 1980 and November 2012 in peer-reviewed journals, English language only involving human subjects. Twenty-one articles were found that met our inclusion criteria. Retrievable articles varied from case reports to clinical trials to review articles of management options. The majority of articles chronicling patient experiences under chiropractic care reported they demonstrated mild to moderate improvements in presenting symptoms. No adverse side effects were reported. This suggests chiropractic care can be considered as an adjunctive therapy for patients with various GI conditions providing there are no co-morbidities.

    Cohen, Fred L.

    2016-01-01

    Background Despite widespread utilization of chiropractic treatment for various ailments, there is a paucity of documentation regarding intracerebral hemorrhage related to chiropractic trauma. Stroke has been reported from cervical manipulation, although with a suggested low incidence. Activator treatment, an instrument that produces a high-velocity, low-amplitude impact to the spine, is considered especially safe. There are no prior reports of intracerebral hemorrhage resulting from a chiropractic activator treatment. Case Description A 75-year-old woman was admitted to the hospital with a history of headaches, visual difficulties on the right, and speech disturbance of relatively acute onset. CT scan showed a brain hemorrhage in an unusual location. Extensive evaluation was undertaken because this was thought to be a spontaneous event. No cause was found on imaging. Subsequent history revealed a chiropractic activator treatment applied directly to the junction of the back of her head and the upper cervical spine immediately prior to the onset of symptoms. Her clinical course is described. Conclusions This appears to be the first report linking traumatic intracerebral hemorrhage with a chiropractic activator treatment. The use of this modality in an elderly population, with widespread utilization of anticoagulants and platelet inhibitors, is of potential concern. PMID:27999766

    2007-01-01

    Objective To conduct a descriptive review of the scientific literature examining use rates of modalities and procedures used by CAM clinicians to manage chronic LBP and other conditions Data Sources A literature of PubMed and MANTIS was performed using the key terms Chiropractic; Low Back Pain; Utilization Rate; Use Rate; Complementary and Alternative Medicine; and Health Services in various combinations. Data Selection A total of 137 papers were selected, based upon including information about chiropractic utilization, CAM utilization and low back pain and other conditions. Data Synthesis Information was extracted from each paper addressing use of chiropractic and CAM, and is summarized in tabular form. Results Thematic analysis of the paper topics indicated that there were 5 functional areas covered by the literature: back pain papers, general chiropractic papers, insurance-related papers, general CAM-related papers; and worker's compensation papers. Conclusion Studies looking at chiropractic utilization demonstrate that the rates vary, but generally fall into a range from around 6% to 12% of the population, most of whom seek chiropractic care for low back pain and not for organic disease or visceral dysfunction. CAM is itself used by people suffering from a variety of conditions, though it is often used not as a primary intervention, but rather as an additional form of care. CAM and chiropractic often offer lower costs for comparable results compared to conventional medicine. PMID:17241465

    Haussler, K K

    1999-04-01

    A thorough knowledge of equine spinal anatomy, biomechanics, and potential pathology is required to understand the principles and theories behind chiropractic and to apply its techniques properly. Chiropractic provides additional diagnostic and therapeutic means that may help equine practitioners to identify and treat the primary cause of lameness or poor performance. Specialized training in the evaluation and treatment of vertebral joint dysfunction and neuromusculoskeletal disorders places chiropractic in the forefront of conservative treatment of spinal-related disorders. Nevertheless, limited research is currently available on equine chiropractic and other nontraditional modalities in veterinary medicine. In 1996, the American Veterinary Medicine Association's Committee on Alternative and Complementary Therapies suggested that the research community should be encouraged to prioritize avenues of research and to allocate research funds to projects that are designed to provide further scientific evaluation of these modalities. The future of equine chiropractic in veterinary medicine is dependent on future research into the clinical effects of chiropractic techniques and the basic pathophysiology of spinal-related disorders in horses.

    Objective The purpose of this case series is to describe the chiropractic management of 21 patients with daily stress and occasional total urinary incontinence (UI). Clinical Features Twenty-one case files of patients 13 to 90 years of age with UI from a chiropractic clinic were reviewed. The patients had a 4-month to 49-year history of UI and associated muscle dysfunction and low back and/or pelvic pain. Eighteen wore an incontinence pad throughout the day and night at the time of their appointments because of unpredictable UI. Intervention and Outcome Patients were evaluated for muscle impairments in the lumbar spine, pelvis, and pelvic floor and low back and/or hip pain. Positive manual muscle test results of the pelvis, lumbar spine muscles, and pelvic floor muscles were the most common findings. Lumbosacral dysfunction was found in 13 of the cases with pain provocation tests (applied kinesiology sensorimotor challenge); in 8 cases, this sensorimotor challenge was absent. Chiropractic manipulative therapy and soft tissue treatment addressed the soft tissue and articular dysfunctions. Chiropractic manipulative therapy involved high-velocity, low-amplitude manipulation; Cox flexion distraction manipulation; and/or use of a percussion instrument for the treatment of myofascial trigger points. Urinary incontinence symptoms resolved in 10 patients, considerably improved in 7 cases, and slightly improved in 4 cases. Periodic follow-up examinations for the past 6 years, and no less than 2 years, indicate that for each participant in this case-series report, the improvements of UI remained stable. Conclusion The patients reported in this retrospective case series showed improvement in UI symptoms that persisted over time. PMID:22942842

    Objective The purpose of this case report is to describe chiropractic management of a patient with overactive bladder (OAB) and to describe an hypothetical anatomical basis for a somato-vesical reflex and possible clinical link between pelvic and symphysis pubis dysfunction to OAB. Clinical features A 24-year-old nulliparous female with idiopathic OAB, with a primary complaint of nocturia presented for chiropractic care. Her sleep was limited to 2 consecutive hours due to bladder urgency. Pubic symphysis shear dysfunction was observed on physical examination. Intervention and outcomes The primary treatment modality used was chiropractic side-posture drop-table manipulation designed to reduce pubic shear dysfunction. After 8 treatments in 1 month, the pubic shear gradually reduced while nocturia diminished and consecutive sleep hours increased from 2 to 7. At 1-year follow-up, the nocturia remained resolved. Conclusion The patient reported in this case responded favorably to chiropractic care, which resulted in reduced nocturia and increased sleep continuity. PMID:25685115

    OBJECTIVES: The purpose of this paper is to describe the demographic and clinical characteristics of chiropractic patients and to document chiropractic visit rates in 6 sites in the United States and Canada. METHODS: Random samples of chiropractors from 5 US sites and 1 Canadian site were selected. A record abstraction system was developed to obtain demographic and clinical data from office charts. RESULTS: Of the 185 eligible chiropractors sampled, 131 (71%) participated. Sixty-eight percent of the selected charts showed that care was sought for low back pain, while 32% recorded care for other reasons. Spinal manipulative therapy was recorded in 83% of all charts. There was a greater than 2-fold difference in the median number of visits related to low back pain per episode of care across sites. The chiropractic visit rates in the US sites and Ontario are estimated to be 101.2 and 140.9 visits per 100 person-years, respectively. CONCLUSIONS: The chiropractic use rate in these sites is twice that of estimates made 15 years ago. The great majority of patients receive care for musculoskeletal conditions of the back and neck. The number of visits per episode varies appreciably by site. PMID:9585743

    1982-06-01

    This survey of the members of the Dade County Chiropractic Society of Miami, Florida was initiated with the encouragement and under the supervision of the Dade County Health Systems Agency (HSA). The purpose of the survey was to obtain information relative to the inclusion of chiropractic into future health planning to be conducted by the HSA. The survey was divided into a "Physicians Survey" obtaining information on location, office hours, gross income, total patient visits and type of practice of the doctor, and a "Patient Survey" obtaining information on age, sex, ethnic origin, residence, and payment source of the patients. Clinical information on initial complaints, diagnoses, treatment, referrals, and amount of care was also obtained. It was found that chiropractors work an average of 31.7 hours per week with a gross annual income of $74,750.00 (1979). The male-female distribution of patients was equal and the average patient age was 43.4 years. Anglocaucasian category comprised 80.2% of the patient sample. Nearly 50% of all chiropractic patients pay for services rendered out of their own pocket. Of the primary diagnosis, 81.3% related to the spine. The study concludes that the practice of chiropractic in Dade County is very similar to the practice of chiropractic in general.

  4. Practice patterns of doctors of chiropractic with a pediatric diplomate: a cross-sectional survey

    PubMed Central

    2010-01-01

    Background Complementary and alternative medicine (CAM) is growing in popularity, especially within the pediatric population. Research on CAM practitioners and their specialties, such as pediatrics, is lacking. Within the chiropractic profession, pediatrics is one of the most recently established post-graduate specialty programs. This paper describes the demographic and practice characteristics of doctors of chiropractic with a pediatric diplomate. Methods 218 chiropractors with a pediatric diplomate were invited to complete our survey using either web-based or mailed paper survey methods. Practitioner demographics, practice characteristics, treatment procedures, referral patterns, and patient characteristics were queried with a survey created with the online survey tool, SurveyMonkey©®. Results A total of 135 chiropractors responded (62.2% response rate); they were predominantly female (74%) and white (93%). Techniques most commonly used were Diversified, Activator ®, and Thompson with the addition of cranial and extremity manipulation to their chiropractic treatments. Adjunctive therapies commonly provided to patients included recommendations for activities of daily living, corrective or therapeutic exercise, ice pack\\cryotherapy, and nutritional counseling. Thirty eight percent of respondents' patients were private pay and 23% had private insurance that was not managed care. Pediatrics represented 31% of the survey respondents' patients. Chiropractors also reported 63% of their work time devoted to direct patient care. Health conditions reportedly treated within the pediatric population included back or neck pain, asthma, birth trauma, colic, constipation, ear infection, head or chest cold, and upper respiratory infections. Referrals made to or from these chiropractors were uncommon. Conclusions This mixed mode survey identified similarities and differences between doctors of chiropractic with a pediatric diplomate to other surveys of doctors of chiropractic

    2013-01-01

    Objective The purpose of this case report is to describe chiropractic management of a patient with arm and hand numbness and who was suspected to have ulnar nerve compression. Clinical Features A 41-year-old woman presented with hand weakness and numbness along the medial aspect of her right forearm and the 3 most medial fingers. The onset of symptoms presented suddenly, 3 weeks prior, when she woke up in the morning and assumed she had “slept wrong.” The patient’s posture showed protracted shoulders and moderate forward head carriage. Orthopedic assessment revealed symptomatic right elevated arm stress test, grip strength asymmetry, and a Tinel sign at the right cubital tunnel. Intervention and Outcome The patient was treated using chiropractic care, which consisted of manipulative therapy, myofascial therapy, and elastic therapeutic taping. Active home care included performing postural exercises and education about workstation ergonomics. She demonstrated immediate subjective improvement of her numbness and weakness after the first treatment. Over a series of 11 treatments, her symptoms resolved completely; and she was able to perform work tasks without dysfunction. Conclusion Chiropractic treatment consisting of manipulation, soft tissue mobilizations, exercise, and education of workstation ergonomics appeared to reduce the symptoms of ulnar nerve compression symptoms for this patient.

  6. A History of Manipulative Therapy

    PubMed Central

    Pettman, Erland

    2007-01-01

    Manipulative therapy has known a parallel development throughout many parts of the world. The earliest historical reference to the practice of manipulative therapy in Europe dates back to 400 BCE. Over the centuries, manipulative interventions have fallen in and out of favor with the medical profession. Manipulative therapy also was initially the mainstay of the two leading alternative health care systems, osteopathy and chiropractic, both founded in the latter part of the 19th century in response to shortcomings in allopathic medicine. With medical and osteopathic physicians initially instrumental in introducing manipulative therapy to the profession of physical therapy, physical therapists have since then provided strong contributions to the field, thereby solidifying the profession's claim to have manipulative therapy within in its legally regulated scope of practice.

    Illes, Jennifer D.; Maola, Chad J.

    2012-01-01

    Objective The purpose of this case report is to describe the chiropractic management of a patient with a unilateral transfemoral amputation and low back pain (LBP). Clinical Features A 20-year-old woman with right transfemoral amputation and a right upper extremity amputation due to amniotic band syndrome had approximately 40 different prosthetic lower extremities in the prior 20 years. She presented for chiropractic care for LBP (5/10 numeric pain scale) that she experienced after receiving a new right prosthetic leg. The pain increased with walking, attempts to exercise, and lying supine. Physical evaluation revealed asymmetrical leg length (long right limb); restricted left ankle dorsiflexion; restricted lumbopelvic motion; and hypertonicity of the left triceps surae muscle complex as well as the gluteus maximus, quadratus lumborum, and erector spinae bilaterally. Gait examination revealed a right Trendelenberg gait as well as a pattern of left vaulting. The working diagnosis was sacroiliac joint dysfunction, with lumbar facet syndrome secondary to a leg length inequality causing alteration in gait. Intervention and Outcome Chiropractic management included manipulative therapy to the lumbar spine and pelvis, trigger point therapy of hypertonic musculature, and strengthening of pelvic musculature. In addition, the patient's prosthetist shortened her new prosthetic device. After 18 treatments, LBP severity was resolved (0/10); and there was an overall improvement with gait biomechanics. Conclusion This case illustrates the importance of considering leg length inequality in patients with amputations as a possible cause of lower back pain, and that proper management may include adjusting the length of the prosthetic device and strengthening of the hip flexors and abductors, in addition to trigger point therapy and chiropractic manipulation.

  9. Applying ‘science’ in chiropractic clinical practice

    PubMed Central

    Jamison, Jennifer R

    1990-01-01

    The chiropractic profession is increasingly expressing the sentiment that chiropractic clinical intervention should rest upon a scientific foundation. Before ‘scientific research’ can become meaningful in chiropractic clinical practice, it is necessary that field practitioners be conversant with research terminology. If chiropractic clinical practice is to achieve credibility as a scientific mode of health care and if the benefits of a ‘scientific’ practice model are to enhance patient care, then future chiropractic practitioners must be familiar with a currently accredited scientific frame of reference. A survey of final year chiropractic students at Phillip Institute of Technology found that respondents appreciation of the strength of diverse clinical research methodologies and their ranking of criteria for ascertaining a cause-effect association bears some similarity (RHO = 0.97 and 0.98 respectively, p < 0.05) to that of the ‘scientific’ clinical community.

  10. Music therapy and chiropractic: an integrative model of tonal and rhythmic spinal adjustment.

    PubMed

    Miller, E B; Redmond, P

    1999-03-01

    There is a philosophical basis for the integration of treatment using music therapy and chiropractic. Perception is intimately linked to the nervous system. A relationship between spinal integrity and consciousness does exist. We can see that as spinal distortions diminish and awareness increases, there is a natural attraction toward the higher or more loving state of consciousness. Rhythms of healing and suffering are a key concept in combining music therapy with chiropractic manipulation. Donald Epstein's conceptualization of the rhythmic stages of consciousness corresponding to prescribed physiological patterns serves as a starting point for the use of rhythm in the healing process. Using interactive music, the music therapist can help facilitate a change in the patient's physical or emotional state. This occurs when the practitioner establishes an initial connection or musical validation of the patient's emotional state and assists the healing process by improvising supportive music while suggesting possibilities for resolution. We believe that the power of music can be used as a significant tool in chiropractic work to aid individuals in their healing process.

    2016-01-01

    Objective The aim of this study was to look for differences between patients with an increased pain response as compared with those with a decreased pain response. Methods Data were collected from consecutive new patients with lumbar or lumbopelvic pain in a chiropractic clinic. A pelvic tilt exercise was included in the initial examination, and pain response was noted. Analysis was made of pain and disability severity, as well as symptom location, chronicity, and other characteristics, before and after a course of chiropractic care. Results Patients with an increased pain response to pelvic tilt (n = 12) had higher levels of pain and disability at baseline than patients without (n = 34). There were no between-group differences in other aspects of their complaints; in age, sex, or body mass; or in the types of care they received (eg, manipulation, stretching, exercise instruction). On the average, both groups of patients showed improvement with chiropractic care, and there was no detectable difference in improvement between groups. Conclusions This study found that patients experiencing pain in response to a pelvic tilt maneuver may have a poorer precare status than patients with a decreased pain response. PMID:27069429

    2008-01-01

    Abstract Objective This case report describes the effect of exercise-based chiropractic treatment on chronic and intractable low back pain complicated by lumbar disk extrusion. Clinical Features A 47-year–old male firefighter experienced chronic, unresponsive low back pain. Pre- and posttreatment outcome analysis was performed on numeric (0-10) pain scale, functional rating index, and the low back pain Oswestry data. Secondary outcome assessments included a 1-rep maximum leg press, balancing times, push-ups and sit-ups the patient performed in 60 seconds, and radiographic analysis. Intervention and Outcome The patient was treated with Pettibon manipulative and rehabilitative techniques. At 4 weeks, spinal decompression therapy was incorporated. After 12 weeks of treatment, the patient's self-reported numeric pain scale had reduced from 6 to 1. There was also overall improvement in muscular strength, balance times, self-rated functional status, low back Oswestry scores, and lumbar lordosis using pre- and posttreatment radiographic information. Conclusion Comprehensive, exercise-based chiropractic management may contribute to an improvement of physical fitness and to restoration of function, and may be a protective factor for low back injury. This case suggests promising interventions with otherwise intractable low back pain using a multimodal chiropractic approach that includes isometric strengthening, neuromuscular reeducation, and lumbar spinal decompression therapy.

    Abstract Objective The purpose of this article is to review the literature on the topic of chiropractic care during pregnancy. Methods A PubMed search was performed using the terms pregnancy and chiropractic. Sources were cross-referenced to obtain further articles and research information after reviewing the articles obtained through the search. Results Thirty-three references were used for this review. The current literature reports favorable results on the use of chiropractic care throughout pregnancy. Conclusions Chiropractic evaluation and treatment during pregnancy may be considered a safe and effective means of treating common musculoskeletal symptoms that affect pregnant patients. The scarcity of published literature warrants further research. PMID:19674697

  14. Does Chiropractic ‘Add Years to Life’?

    PubMed Central

    Morgan, Lon

    2004-01-01

    The chiropractic cliché “Chiropractic Adds Life to Years and Years to Life” was examined for validity. It was assumed that chiropractors themselves would be the best informed about the health benefits of chiropractic care. Chiropractors would therefore be most likely to receive some level of chiropractic care, and do so on a long-term basis. If chiropractic care significantly improves general health then chiropractors themselves should demonstrate longer life spans than the general population. Two separate data sources were used to examine chiropractic mortality rates. One source used obituary notices from past issues of Dynamic Chiropractic from 1990 to mid-2003. The second source used biographies from Who Was Who in Chiropractic – A Necrology covering a ten year period from 1969–1979. The two sources yielded a mean age at death for chiropractors of 73.4 and 74.2 years respectively. The mean ages at death of chiropractors is below the national average of 76.9 years and is below their medical doctor counterparts of 81.5. This review of mortality date found no evidence to support the claim that chiropractic care “Adds Years to Life.” PMID:17549121

    2014-01-01

    Objective The purpose of this case report is to describe the chiropractic and dental comanagement of a patient with temporomandibular dysfunction, headaches, and myalgia. Clinical features A 38-year-old black female patient presented for chiropractic care with a chief concern of jaw pain, tinnitus, headaches, and neck and shoulder soreness of 8 months’ duration. The patient rated the pain a 6/10. The patient had a maximum mouth opening of 42 mm, graphed evidence of disk displacement, loss of translation on opening of the right temporomandibular joint viewed on the lateral radiograph, and numerous areas of point tenderness on the Kinnie-Funt Chief Complaint Visual Index. She had decreased lateral cervical flexion. Intervention and outcome Dental treatment consisted of an anterior repositioning splint. Chiropractic care consisted of Activator treatment to the pelvis and the thoracic and cervical spine. Manual manipulation of the temporomandibular joint was performed along with a soft tissue technique intraorally on the lateral pterygoid. Postisometric relaxation in the head and neck region was also done. The patient was treated 6 times over 3 weeks. At the end of treatment, the patient had a pain rating of 0/10, maximum mouth opening of 49 mm, no tender points on the follow-up Kinnie-Funt, and increased cervical range of motion. Conclusion The patient demonstrated increased mouth opening, decreased pain rating, improved Kinnie-Funt visual index, and an increased cervical lateral flexion range of motion after 3 weeks of a combination of chiropractic and dental care.

  16. Nitric oxide: a challenge to chiropractic

    PubMed Central

    Morgan, Lon

    2000-01-01

    The 1998 Nobel Prize in Physiology or Medicine recognized the biological significance of nitric oxide. Nitric oxide is derived from the amino acid arginine. It is intimately involved with circulatory vessel dilation where, for example, it protects against heart attacks, and is the basis for new medications such as Sildenafil (Viagra). Nitric oxide acts as a neurotransmitter and can modulate many neurological reactions. The immune system uses nitric oxide to destroy pathogens by interfering with key enzymes. Nitric oxide is responsible for both osteoclastic and osteoblastic responses in bone and is a key player in the degenerative aspects of arthritis. The process of apoptosis employs nitric oxide in the orderly removal of unneeded cells. There is clear evidence that major signaling and control mechanisms exist in the body apart from the nervous system. Chiropractic is thus faced with the challenge of how to incorporate this new knowledge which conflicts with traditional chiropractic concepts.

    2012-01-01

    As the diversity of the United States (US) population continues to change, concerns about minority health and health disparities grow. Health professions must evolve to meet the needs of the population. The purpose of this editorial is to review current trends in the diversity of chiropractic students, faculty, and practitioners in the United States. This editorial was informed by a search of the literature, to include PubMed, using the terms chiropractic and diversity, minority, and cultural competency. Demographic information for the chiropractic profession was obtained from the National Board of Chiropractic Examiners and The Chronicle of Higher Education. These data were compared to diversity data for medical doctors and the national and state populations from the American Association of Medical Colleges and the US Census, respectively. Surprisingly little has been published in the peer-reviewed literature on the topic of diversity in the chiropractic profession. For the variables available (sex and race), the data show that proportions in the US chiropractic profession do not match the population. State comparisons to associated chiropractic colleges show similar relationships. No reliable data were found on other diversity characteristics, such as gender identity, religion, and socioeconomic status. The chiropractic profession in the United States currently does not represent the national population with regard to sex and race. Leaders in the profession should develop a strategy to better meet the changing demographics of the US population. More attention to recruiting and retaining students, such as underrepresented minorities and women, and establishing improved cultural competency is needed.

  1. McTimoney chiropractic: a gentle way with back pain.

    PubMed

    Cartlidge, S

    1997-10-01

    There are 1080 chiropractors in the UK today, and almost one-third of these are McTimoney chiropractors. This article outlines the development of McTimoney Chiropractic, which is a particular branch of the chiropractic profession in the UK, taught at the McTimoney Chiropractic College in Abingdon, near Oxford. The McTimoney method is distinguished by its gentle, whole body approach. It aims to correct the alignment of the bones of the spine and other joints of the body, to restore nerve function, to alleviate pain, and to promote natural health. The technique is suitable for the very young as well as the old and frail. In this paper, several nurses-turned-chiropractor offer their personal views. Reference is also made to the McTimoney-Corley technique, which is a similar chiropractic method taught at the Oxford School of Chiropractic, UK.

    PubMed

    Budgell, Brian S; Kwong, Alice; Millar, Neil

    2013-03-01

    This study investigates how the language of chiropractic has changed over time. A collection of material, published up until approximately 1950 and consisting of textbooks, monographs and lecture notes from Canadian Memorial Chiropractic College, was analyzed to identify commonly occurring words and phrases. The results were compared to a corpus of recent articles from the Journal of the Canadian Chiropractic Association. This permitted the identification of words which were over-represented in the historical literature and therefore likely have become somewhat archaic or represent themes which are of less import in the modern chiropractic literature. Words which were over-represented in the historical literature often referred to anatomical, pathological and biomechanical concepts. Conversely, words which were comparatively over-represented in the modern chiropractic literature often referred to concepts of professionalism, the clinical interaction and evidence-based care. A detailed analysis is presented of trends in the use of the conceptually important terms subluxation and adjustment.

  3. Chiropractic management of episodic tension-type headache: a survey of clinical specialists

    PubMed Central

    Vernon, Howard; McDermaid, Cameron

    1998-01-01

    Tension-type headache (TTH) is a highly prevalent condition experienced annually by 30-70% of the population. As a chief complaint, it occupies 5-8% of chiropractors’ caseloads, but is probably more prevalent in multiple complaint cases. While numerous clinical descriptions exist in the literature of the management of TTH by chiropractors, and while there is a small body of clinical trials of the treatment of non-migrainous headache by spinal manipulation, there is no systematic survey of the approaches to its treatment by chiropractors. The goals of this study were to determine the test-retest reliability of a questionnaire designed to identify the most commonly used treatments for TTH and to report on any consistent findings as a potential profile of typical practice approach. The respondents consisted of a group of Canadian chiropractic clinical specialists. Respondents were asked to complete a survey which consisted of a comprehensive list of chiropractic treatment procedures including standard manual manipulations and mobilisations, soft tissue therapies, modalities, exercises, behavioral therapies, acupuncture, nutrition and four “systems” techniques. The respondents were asked to rate their frequency of use of these procedures on a 4-point scale ranging from “always” to “never”. The surveys were completed twice within a two day interval. The response rate was 18/25 (72%). Eighty-seven percent (87%) of the items were rated identically on both surveys. All but one of the items achieved a statistically significant reliability coefficient. The highest rated items were “upper cervical manipulations”, “upper cervical soft tissue therapy” and “neck stretching exercises”. The items which received the lowest endorsement were: chiropractic procedures to the dorso-lumbo-pelvic spine, most therapy modalities and the “systems” techniques which were included in the survey. Years in practice appeared to have very little effect on the use of

  4. Spinal manipulation as a valid treatment for low back pain.

    PubMed

    Vernon, L F

    1996-03-01

    The practice of chiropractic has been regulated in the State of Delaware since 1937. Since that time, the battle lines in the state between medicine and chiropractic have been drawn. This war has existed on both the political and clinical fronts, and although it has always been believed by the chiropractic profession that once the "scientific evidence" of the benefit of chiropractic was proven, the war would end. This has not occurred to the extent believed. Even with its 1980 victory over the AMA, chiropractic has still been unable to achieve full acceptance as a clinical discipline among other professions. Many hospitals in this country have opened their doors to DCs. This by and large, has solely been for economic reasons and not as a recognition of the clinical benefit of manipulation. There is, however, a growing population of primary care physicians and researchers suggesting the benefit of manipulation for low back pain as well as suggesting that increased cooperation between MDs and DCs could be of extreme benefit to the patient population at large. This group continues to be in the minority. However, with increased knowledge of the benefits of spinal manipulation and the scientific evidence that now exists to support its efficacy, it is now believed that this interprofessional referral pattern will increase. In addition, many managed care programs now require primary care physicians to determine the necessity for referral to a chiropractor, thus causing a need for the primary physician to have some knowledge of spinal manipulation. This paper is presented to inform the physician community of Delaware of some of the evidence pointing to the efficacy of spinal manipulation as a treatment for low back pain.

  5. The biomechanics of spinal manipulation.

    PubMed

    Herzog, Walter

    2010-07-01

    Biomechanics is the science that deals with the external and internal forces acting on biological systems and the effects produced by these forces. Here, we describe the forces exerted by chiropractors on patients during high-speed, low-amplitude manipulations of the spine and the physiological responses produced by the treatments. The external forces were found to vary greatly among clinicians and locations of treatment on the spine. Spinal manipulative treatments produced reflex responses far from the treatment site, caused movements of vertebral bodies in the "para-physiological" zone, and were associated with cavitation of facet joints. Stresses and strains on the vertebral artery during chiropractic spinal manipulation of the neck were always much smaller than those produced during passive range of motion testing and diagnostic procedures.

    2012-01-01

    Objectives This report describes the case of a patient with chronic idiopathic meralgia paresthetica associated with bilateral sacroiliac joint dysfunction who was managed with chiropractic care. Clinical Features A 35-year-old white woman presented to a private chiropractic clinic with a complaint of numbness in the right anterolateral thigh region. Neurological assessment revealed a diminution of sensibility and discrimination on the right lateral femoral cutaneous nerve territory. Pain was rated as 8.5 on a numeric pain scale of 0 to 10. Musculoskeletal examination of the pelvic region disclosed bilateral sacroiliac joint dysfunction. Intervention and Outcomes Chiropractic management included pelvic mobilizations, myofascial therapy, transverse friction massage, and stretching exercises. After 3 visits (2 weeks later), result of neurological evaluation was normal, with no residual numbness over the lateral thigh. Conclusion In the present case, chiropractic management with standard and applied kinesiology techniques resulted in recovery of meralgia paresthetica symptoms for this patient. PMID:22942840

    PubMed

    Sawyer, C; Haas, M; Nelson, C; Elkington, W

    1997-01-01

    In the current climate of accountability, health care financing reform and the demand on all health professions for evidence, there is an urgent need to expand clinical research activity within the profession. Those randomized clinical trials that have been reported in the literature have focused primarily on low back and headache pain. Only recently have studies been initiated to investigate the effectiveness of chiropractic interventions for conditions other than back pain. The ability of chiropractic colleges to develop research infrastructures and productive clinical research programs depends on removing or minimizing a number of impediments. A shortage of chiropractic clinicians who have the experience and training to conduct clinical research is compounded by a dependency on tuition revenue, limited external funding and a lack of institutional emphasis on research. The profession generally, and chiropractic colleges specifically, must address the impediments that limit the growth of research capacity. We present several recommendations and the action steps required to achieve specific outcomes.

    Background Moderately convincing evidence supports the benefits of chiropractic manipulations for low back pain. Its effectiveness in other applications is less well documented, and its cost-effectiveness is not known. These questions led the Centers for Medicaid and Medicare Services (CMS) to conduct a two-year demonstration of expanded Medicare coverage for chiropractic services in the treatment of beneficiaries with neuromusculoskeletal (NMS) conditions affecting the back, limbs, neck, or head. Methods The demonstration was conducted in 2005–2007 in selected counties of Illinois, Iowa, and Virginia and the entire states of Maine and New Mexico. Medicare claims were compiled for the preceding year and two demonstration years for the demonstration areas and matched comparison areas. The impact of the demonstration was analyzed through multivariate regression analysis with a difference-in-difference framework. Results Expanded coverage increased Medicare expenditures by $50 million or 28.5% in users of chiropractic services and by $114 million or 10.4% in all patients treated for NMS conditions in demonstration areas during the two-year period. Results varied widely among demonstration areas ranging from increased costs per user of $485 in Northern Illinois and Chicago counties to decreases in costs per user of $59 in New Mexico and $178 in Scott County, Iowa. Conclusion The demonstration did not assess possible decreases in costs to other insurers, out-of-pocket payments by patients, the need for and costs of pain medications, or longer term clinical benefits such as avoidance of orthopedic surgical procedures beyond the two-year period of the demonstration. It is possible that other payers or beneficiaries saved money during the demonstration while costs to Medicare were increased. PMID:26928221

    Presented here is a narrative review of upper cervical procedures intended to facilitate understanding and to increase knowledge of upper cervical chiropractic care. Safety, efficacy, common misconceptions, and research are discussed, allowing practitioners, chiropractic students, and the general public to make informed decisions regarding utilization and referrals for this distinctive type of chiropractic care. Upper cervical techniques share the same theoretical paradigm in that the primary subluxation exists in the upper cervical spine. These procedures use similar assessments to determine if spinal intervention is necessary and successful once delivered. The major difference involves their use of either an articular or orthogonal radiograph analysis model when determining the presence of a misalignment. Adverse events following an upper cervical adjustment consist of mild symptomatic reactions of short-duration (< 24-hours). Due to a lack of quality and indexed references, information contained herein is limited by the significance of literature cited, which included non-indexed and/or non-peer reviewed sources.

  10. The origins and early history of the National Chiropractic Association

    1993-01-01

    Early organization in chiropractic was prompted by the profession’s need to promote itself and to defend against the onslaught of political medicine and organized osteopathy. The first priorities were legal defense against prosecution for unlicensed practice and malpractice insurance. The Universal Chiropractors’ Association (UCA), organized at the Palmer School of Chiropractic (PSC) in 1906, sought to meet these needs by insuring its members and by developing a legal department under the supervision of attorney Tom Morris, one time lieutenant governor of Wisconsin. The public relations and marketing needs of chiropractors were largely served by the PSC and its legendary leader. However, as chiropractors increasingly sought to avoid prosecution by passage of chiropractic laws, Palmer’s efforts to direct this legislation so as to limit chiropractors’ scope of practice increasingly alienated many in the profession. The American Chiropractic Association (ACA) was founded in 1922 to provide a broadscope alternative to BJ’s UCA. With Palmer’s departure from the UCA following the neurocalometer debacle, ACA and UCA sought amalgamation. Simultaneously, organized medicine renewed its attack on the profession by introducing basic science legislation, which prompted chiropractors to try to upgrade and standardize chiropractic education. Early efforts to bring about the needed consensus were centered in the International Chiropractic Congress (ICC), particularly its division of state examining boards. In 1930 the ACA and UCA combined to form the National Chiropractic Association (NCA), and by 1934 the ICC had merged with the NCA to form part of its council structure. With this modicum of solidarity the NCA began the process of educational boot-strapping at its 1935 convention in Los Angeles, when its Committee on Education, a forerunner of today’s Council on Chiropractic Education, was proposed by C.O. Watkins of Montana. ImagesFigure 2Figure 3Figure 4Figure 5

  11. The evidence base for chiropractic treatment of musculoskeletal conditions in children and adolescents: The emperor's new suit?

    Five to ten percent of chiropractic patients are children and adolescents. Most of these consult because of spinal pain, or other musculoskeletal complaints. These musculoskeletal disorders in early life not only affect the quality of children's lives, but also seem to have an impact on adult musculoskeletal health. Thus, this is an important part of the chiropractors' scope of practice, and the objective of this review is to assess the evidence base for manual treatment of musculoskeletal disorders in children and adolescents.Randomized, quasi-randomized and non-randomized clinical studies were included if they investigated the effect of manual therapy on musculoskeletal disorders in children and/or adolescents. The MEDLINE and MANTIS databases were searched, and studies published in English, Danish, Swedish or Norwegian were included.Only three studies were identified that in some way attempted to look at the effectiveness of manual therapy for children or adolescents with spinal problems, and none of these was a randomized controlled clinical trial. As for the rest of the musculoskeletal system, only one study of temporomandibular disorder was identified.With this review, we have detected a paradox within the chiropractic profession: Although the major reason for pediatric patients to attend a chiropractor is spinal pain, no adequate studies have been performed in this area. It is time for the chiropractic profession to take responsibility and systematically investigate the efficiency of joint manipulation of problems relating to the developing musculoskeletal system.

    2012-01-01

    Objective The purpose of this article is to present the case of a patient with an anatomical anomaly of the piriformis muscle who had a piriformis syndrome and was managed with chiropractic care. Case Report A 32-year-old male patient presented to a chiropractic clinic with a chief complaint of low back pain that radiated into his right buttock, right posterior thigh, and right posterior calf. The complaint began 5 years prior as a result of injuries during Airborne School in the US Army resulting in a 60% disability rating from the Veterans Administration. Magnetic resonance imaging demonstrated a mildly decreased intradiscal T2 signal with shallow central subligamentous disk displacement and low-grade facet arthropathy at L5/S1, a hypolordotic lumbar curvature, and accessory superior bundles of the right piriformis muscle without morphologic magnetic resonance imaging evidence of piriformis syndrome. Intervention and Outcome Chiropractic treatment included lumbar and sacral spinal manipulation with soft tissue massage to associated musculature and home exercise recommendations. Variations from routine care included proprioceptive neuromuscular facilitation stretches, electric muscle stimulation, acupressure point stimulation, Sacro Occipital Technique pelvic blocking, CranioSacral therapy, and an ergonomic evaluation. Conclusion A patient with a piriformis anomaly with symptoms of low back pain and piriformis syndrome responded positively to conservative chiropractic care, although the underlying cause of the piriformis syndrome remained.

    Objective This research aimed to investigate motivations for studying chiropractic, and to determine what students look for in a course/college and potential barriers to studying chiropractic. Methods The study design was a cross-sectional survey. Following IRB/Ethical approval, a paper-based questionnaire was distributed to students at McTimoney College of Chiropractic. Demographic data were compared to another chiropractic college in the United Kingdom. Results The questionnaire response rate was 70.8% (n = 121). Motivating factors for studying chiropractic included a desire to help others (54.5%, n = 66), with 44.6% (n = 54) attracted by chiropractic's holistic, drugless approach to health. Previous help from chiropractic influenced 55.4% (n = 67) and 22.3% (n = 27) felt chiropractic had “changed their life.” Just over half of the respondents (55.4%, n = 67) viewed the ability to work while studying as extremely important and 73.6% (n = 89) said they could not have studied chiropractic without this. Conclusion Previous help from chiropractic care was a common motivation for studying chiropractic. The ability to work while studying was seen as vital by many students and, without it, the vast majority felt they could not have studied chiropractic. PMID:23957323

    Senzon, Simon A.

    2011-01-01

    Objective The philosophy of chiropractic can be framed as an attempt to correct the problems inherited from the Western Enlightenment. Its origins can be found in the long tradition of Western philosophy. The purpose of this article is to describe in a broad context chiropractic’s roots in premodernity and establish the structural and hermeneutical differences between chiropractic’s original philosophical ideas and those of premodern philosophers. Discussion The worldview or cultural mindset the philosophy arose from must be situated in the context of its time, the birth of the unique postmodern worldview, aperspectival consciousness, and the modern sense of self. This is accomplished by exploring several metatheories about the development of the self through history, with an emphasis on the premodern roots to the chiropractic terms; Universal Intelligence and Innate Intelligence. By contextualizing the philosophy of chiropractic in terms of a structural genealogy of the self and of ideas, a new approach to philosophy in chiropractic emerges. Conclusion Without accounting for chiropractic’s origins as a reflection of the unique time, place, and culture, in terms of the evolution of worldviews through history, any approach to construct or reconstruct a philosophy of chiropractic will potentially miss the seminal feature of chiropractic’s emergence.

  17. Feasibility of Using the Patient-Reported Outcomes Measurement Information System in Academic Health Centers: Case Series Design on Pain Reduction After Chiropractic Care

    PubMed Central

    Burke, Jeanmarie R.

    2014-01-01

    Objective The purpose of this study was to test the utility of Patient-Reported Outcomes Measurement Information System (PROMIS) as a resource for collecting data on patient-reported outcomes (PRO) within academic health centers at a chiropractic college; and, to describe changes in PRO following pragmatic chiropractic care incorporating instrument-assisted soft tissue mobilization (IASTM) on pain symptoms. Methods This was a pre-post intervention design without a control group (case series) involving 25 patients (14 females and 11 males; 40.5 ± 16.39 years, range 20-70 years) who completed their chiropractic care and their baseline and post-treatment pain assessments. The pragmatic chiropractic care intervention included both spinal manipulation and IASTM to treat pain symptoms. PRO’s were collected using PROMIS to measure pain behavior, pain interference and pain intensity. Results The average pre-post assessment interval was 33 ± 22.5 days (95% CI, 23-42 days). The durations of treatments ranged from one week to 10 weeks. The median number of IASTM treatments was six. Pre-post decreases in T-scores for pain behavior and pain interference were 55.5 to 48.4 and 57.7 to 48.4, respectively (P < .05). Only 12 patients had a baseline T-score for pain intensity greater than 50. The pre-post decrease in pain intensity T-scores for these 12 patients was from 53.4 to 40.9. Conclusion Within the limitations of a case series design, these data provide initial evidence on the utility of PROMIS instruments for clinical and research outcomes in chiropractic patients.

    2015-01-01

    Objective This study sought to determine congruence between student assessment tasks within the master of chiropractic curriculum at Macquarie University and 2 separate but related domains: (1) disorders commonly presenting to chiropractors and (2) musculoskeletal conditions for which there is published evidence that chiropractic treatment is effective. Methods A literature review was undertaken to determine which musculoskeletal disorders commonly present to chiropractors and the conditions for which there is published evidence that chiropractic treatment is effective. These 2 domains were then mapped to the assessment tasks within the curriculum and analyzed. The proportion of time allocated to theory versus skill acquisition was also determined. Results Assessment tasks within the curriculum specifically focus on low back pain, neck pain, lower extremity pain, thoracic pain, and adhesive capsulitis. This curriculum mapping demonstrates congruence between the student assessment tasks and published evidence for chiropractic. The assessments also contain an appropriate balance between theory and skills acquisition. Conclusion There is congruence between the assessment tasks within the curriculum and the 2 domains against which it was mapped. Thus, completion of the curriculum provides training relevant to conditions that commonly present to chiropractors and musculoskeletal conditions for which chiropractic treatment is effective.

    A case of chronic neck and low back pain, resistant to standard chiropractic management of manipulation/adjustment and verbal exercise instruction is presented. Identification of psychosocial factors and deconditioning, with a subsequent three month program of in-office rehabilitation including supervised progressive/resistance exercises and behavioural therapy was administered in conjunction with spinal manipulation/adjustment and passive modalities. The program proved effective in reducing the patient’s neck and low back pain. The beneficial effect of supervised exercises and behavioural therapy in patient management is illustrated.

    1994-01-01

    This study was a preliminary investigation into the knowledge of and current attitudes towards the chiropractic profession by medical practitioners with varying years of clinical experience. A questionnaire was designed and mailed to seventy general practitioners in Downsview, Ontario who agreed to participate in the study. Twenty-six were returned for a response rate of 37%. The data were analyzed and responses from doctors with differing years of practice experience were compared using the chi square statistic. When comparing attitudes towards the chiropractic profession between medical practitioners with greater and less than 15 years of clinical experience a statistically significant difference was found (p = 0.0005). However, no significant differences were observed in terms of their interaction with or knowledge of the chiropractic profession. Further, 88% of respondents reported that they had referred a patient to a chiropractor. The limitations of the study and suggestions for improvement are discussed.

  1. Chiropractic quality assurance: standards and guidelines

    PubMed Central

    Gatterman, Meridel I; Dobson, Thomas P; LeFevbre, Ron

    2001-01-01

    Chiropractic quality assurance involves development of both clinical guidelines and standards. Confusion generated by poor differentiation of guidelines from standards contributes to mistrust of the guideline development process. Guidelines are considered to be recommendations that allow for flexibility and individual patient differences. Standards are more binding and require a high level of supporting evidence. While guidelines serve as educational tools to improve the quality of practice, standards that outline minimum competency are used more as administrative tools on which to base policy. Barriers to development of clinical guidelines and standards include fear that they will create prescriptive “cookbook” practice, and the distrust that guidelines are developed primarily for cost containment. Clinicians also criticize guidelines developed by academics that don't relate to practice, and those based on evidence that lacks clinical relevance. Conflicting guidelines perceived to be based on strong bias or conflict of interest are also suspect. To reduce barriers to acceptance and implementation, guidelines should be inclusive, patient-centered, and based on a variety of evidence and clinical experience.

  2. Contemporary chiropractic practice in the UK: a field study of a chiropractor and his patients in a suburban chiropractic clinic

    PubMed Central

    2013-01-01

    Background Two recent surveys of chiropractors in Great Britain suggest that there are discrepancies between chiropractic practice as defined in regulatory guidelines and day-to-day chiropractic clinical practice and there is in general a paucity of information regarding the characteristics of contemporary chiropractic practice in the United Kingdom. This field study describes the daily practice of a contemporary British UK-trained chiropractor. Methods The fieldwork took place during the spring and summer of 2008 when the author spent one day per week observing consultations and interviewing patients in a chiropractic clinic. The chiropractor was subjected to interviews on two occasions. The author also registered as a patient. Field notes were taken by the author, interviews were recorded and the transcripts were corrected and analysed by the author. Results A total of 25 patients took part in the study. The interaction that took place between patients and staff in reception could be considered as a prelude to consultation facilitating the transformation from individual to patient and back to individual. Coupled with the continuous physical contact between the chiropractor and each patient there was a substantial amount of verbal and non-verbal communication throughout treatment visits. The patients presented with predominantly musculo-skeletal pain and the majority had consulted the chiropractor as a result of recommendations from others in their close social environment. The majority of the interviewed patients had either an inaccurate or at best rudimentary understanding of the mechanisms of chiropractic treatment. A few of the interviewed patients indicated that they had at first experienced concerns about the nature of chiropractic treatment or getting undressed. The author was able to gain some insight into how the chiropractor's experiences, opinions and beliefs had shaped his approach to chiropractic treatment and how this formed the basis of his clinical

    2016-01-01

    Introduction: There is no high quality evidence on which to judge the generalizability of isolated reports of improvement in vision following manipulation. The current paucity of research results also precludes the thoughtful design of a controlled, prospective clinical study. Hence, the purpose of the current study was to test the feasibility of conducting a clinical trial of the acute effects of spinal manipulation on visual acuity. Methods: New adult patients presenting to a community based chiropractic clinic were recruited into a single cohort prospective trial to determine the immediate effects of cervical spinal manipulation on visual acuity. Results: The experimental protocol was well accepted by patients and caused minimal or no disruption of the clinic routine. By some measures, chiropractic treatment was accompanied by statistically significant improvements in visual acuity. Discussion: The results of this study indicate that it is quite feasible to conduct a prospective, community based clinical study of the acute effects of spinal manipulation on visual acuity.

    Green, Bart N.; Johnson, Claire D.

    2009-01-01

    Objective: This paper presents the origins and development of the organized chiropractic orthopedics movement in the United States from 1954–1973. Methods: Hand searches of early periodicals were performed and information was organized chronologically to create a timeline. Context for the timeline was provided by extracting pertinent information from audio recordings of interviews. Relevant background information was located using the cumulative index of the journal Chiropractic History and searching the MANTIS database. Historical Features: After World War I, The advent of third party reimbursement for health care created a new environment for health care practitioners. For doctors of chiropractic, this event provided the impetus to begin the postgraduate chiropractic orthopedics program over 50 years ago. In 1954, Alvin A. Hancock, DC and F. Maynard Lipe, DC successfully launched an active orthopedics movement after several earlier attempts failed during the 1940s and early 1950s. The movement generated from the desire to train and certify chiropractors to manage personal injury and workers’ compensation low back injuries. In addition to developing interdisciplinary educational programs, the chiropractic orthopedics group was responsible for producing a research agenda, some of the profession’s early orthopedic-focused research, and for starting the National Council on Chiropractic Orthopedics of the National Chiropractic Association, which later became the American Chiropractic Association Council on Orthopedics. These organizations produced thousands of specialists in chiropractic orthopedics, later known as Diplomates of the American Board of Chiropractic Orthopedists. Conclusion: Several orthopedics interest groups were formed and credentialing processes were created to qualify doctors as recognized chiropractic orthopedics specialists. The popularity of this movement resulted in the inclusion of orthopedics into core chiropractic college curricula and

    This case report describes the chiropractic management of a 30-year-old female patient with severe postpartum pelvic pain secondary to pubic symphysis diastasis. No literature was found on the chiropractic management of postpartum symphysis pubis diastasis. The existing literature concerning chiropractic care for symphysis pubis dysfunction during pregnancy is limited and indicates a potential benefit. Separation of the pubic symphysis may include ligamentous injury to the sacroiliac joints and may lead to chronic pain. Pubic symphysis separation of 17 millimeters was present on digital radiograph. Management consisted of chiropractic adjustments, trigger point release, electrical stimulation, moist heat, sacroiliac belt, and specific stabilizing exercises. The patient's pain improved immediately following treatment on the initial visit. Pain was reduced from 8/10 VAS at the first visit to 2/10 at the fourth visit. She was able to resume normal activities and reached a final pain level of 1/10. The diastasis was reduced by 7 millimeters at 14-weeks post radiograph for a final separation of just under 10 millimeters. Collaboration between obstetricians, midwives and chiropractors may be warranted.

    Sergent, Adam W.; Cofano, Gregory P.

    2014-01-01

    Objective The purpose of this case study is to describe the chiropractic care of a patient with headaches and dizziness. Clinical Features A 34-year-old woman with a history of headaches, dizziness, photophobia, and temporary loss of vision aggravated by postural positions while bending forward sought conservative care for her symptoms. She reported a prior diagnosis of Arnold-Chiari malformation (ACM) type 1 by magnetic resonance imaging in 2005 that revealed descending cerebellar tonsils measured at 5 mm with an impression of ACM type 1. A new magnetic resonance image taken in 2013 indicated the cerebellar tonsils measured at 3 mm and did not project through the plane of the foramen magnum. The diagnosis of ACM type 1 was no longer applicable; however, the signs and symptoms of ACM type 1 persisted. Intervention and Outcome She was treated using cervical chiropractic manipulation using diversified technique. The dizziness and headache were resolved after 3 visits. At her 3-month follow-up, she continued to be symptom-free. Conclusion A patient with headaches and dizziness and a previous diagnosis of ACM type 1 responded positively to chiropractic care.

    2013-01-01

    Objective Concussion is a common sporting injury that may be seen by doctors of chiropractic and should be managed following current practice guidelines. The purpose of this abstract is to present a literature review on chiropractic management of concussion in sport and to discuss current guidelines. Methods A review of the literature was performed using the PubMed search engine. MeSH terms included chiropractic and concussion. Search dates were the beginning of the record through July 30, 2013. All languages and article types were included in the search. Articles found were retrieved and evaluated for the relevance of chiropractic management of concussion in sport. Results Five articles were found (1 prospective study, 1 survey, 3 literature reviews) ranging in publication years from 1993 to 2012. No articles reported a position statement, and none provided a review of current concussion management practices related to chiropractic practice. No articles reported adverse outcomes of chiropractic management of an athlete with concussion. Conclusion Research related to the chiropractic management of concussion in sport is a nascent area of investigation. Although there are few published articles, the articles in this review showed that doctors of chiropractic encounter concussed athletes at events and in clinical practice. It is essential for doctors of chiropractic to understand the importance of using standardized concussion assessment tools and current concussion guidelines. PMID:24396325

    2013-02-01

    The usefulness of chiropractic for treatment of low back pain is a contentious issue. Chiropractors advocate holism and general well-being as a key principle on which they base their clinical practice, yet the quality of life, lifestyle, health and economic impacts of chiropractic intervention for back pain in adults have rarely been investigated. This article provides an overview of chiropractic principles and practices, together with the results of a systematic review of peer-reviewed publications between 2000 and 2010 retrieved from MEDLINE, CINAHL, EMBASE, AMED and Cochrane Database of Systematic Reviews. This review sought to determine the benefits of chiropractic treatment and care to well-being, and to what extent chiropractic treatment and care improve quality of life. Of 1,165 articles, 12 articles were retained, representing six studies (four randomised controlled trial, two observational) of varying quality. There was a high degree of inconsistency and lack of standardisation in measurement instruments and outcome measures. Three studies reported reduced use of other/extra treatments as a positive outcome; two studies reported a positive effect of chiropractic intervention on pain, and two studies reported a positive effect on disability. The six studies reviewed concentrated on the impact of chiropractic care on physical health and disability, rather than the wider holistic view which was the focus of this study. It is difficult, therefore, to defend any conclusion about the impact of chiropractic intervention on the quality of life, lifestyle, health and economic impact on chiropractic patients presenting with back pain.

  11. GPs opinions and perceptions of chiropractic in Sweden and Norway: a descriptive survey

    PubMed Central

    2013-01-01

    Background In Sweden, chiropractic is not included in mainstream health care. In Norway chiropractic is a recognized health care profession. The aim of this study was to explore the perceptions of chiropractic among Swedish and Norwegian General Practitioners (GPs). Methods Eight hundred surveys in each country were distributed randomly by post to Swedish and Norwegian GPs offices. The survey contained two main sections: Experiences and opinions about chiropractic and referral patterns. The data were then described and compared between the countries. Results In Sweden the response rate was 44.8% and in Norway 45.3%. More than half of the Swedish GPs participating in this study stated that they had poor knowledge about chiropractic, while just a tenth of Norwegian GPs stated the same. Nearly all Norwegian GPs had some experience of chiropractic treatment whilst a fairly large number of the Swedish GPs said that they had no experience at all of chiropractic. It was twice as common for GPs in Norway to refer patients to a chiropractor as compared to Sweden. However, Swedish and Norwegian GPs agreed that chiropractors were competent to treat musculo-skeletal conditions with an adequate education to be part of mainstream medicine. Conclusions Swedish and Norwegian GPs agree that chiropractors are competent to treat musculoskeletal conditions. However, there are many differences in GPs perceptions of chiropractic between the two countries and the overall picture indicates that chiropractic is more accepted and recognised as a health care profession in Norway.

    2014-01-01

    Background Research involving chiropractors is evolving and expanding in Europe while resources are limited. Therefore, we considered it timely to initiate a research agenda for the chiropractic profession in Europe. The aim was to identify and suggest priorities for future research in order to best channel the available resources and facilitate advancement of the profession. Methods In total, 60 academics and clinicians working in a chiropractic setting, and who had attended any of the annual European Chiropractors’ Union/European Academy of Chiropractic (ECU/EAC) Researchers’ Day meetings since their inception in 2008, were invited to participate. Data collection consisted of the following phases: phase 1 identification of themes; phase 2 consensus, which employed a Delphi process and allowed us to distill the list of research priorities; and phase 3 presentation of the results during both the Researchers’ Day and a plenary session of the annual ECU Convention in May 2013. In addition, results were distributed to all ECU member countries. Results The response rate was 42% from phase 1 and 68% from phase 2. In general, participants were middle-aged, male and had been awarded a Doctor of Philosophy (PhD) as well as chiropractic degree. Approximately equal numbers of participants had obtained their chiropractic degree from the UK/Europe and North America. The majority of participants worked primarily in an academic/research environment and approximately half worked in an independent institution. In total, 58% of the participants were from the UK and Denmark, collectively representing 44% of the chiropractors working in Europe. In total, 70 research priorities were identified, of which 19 reached consensus as priorities for future research. The following three items were thought to be most important: 1) cost-effectiveness/economic evaluations, 2) identification of subgroups likely to respond to treatment, and 3) initiation and promotion of collaborative

    OBJECTIVE To provide an evidence-based clinical practice guideline for the chiropractic cervical treatment of adults with acute or chronic neck pain not due to whiplash. This is a considerable health concern considered to be a priority by stakeholders, and about which the scientific information was poorly organized. OPTIONS Cervical treatments: manipulation, mobilization, ischemic pressure, clinic- and home-based exercise, traction, education, low-power laser, massage, transcutaneous electrical nerve stimulation, pillows, pulsed electromagnetic therapy, and ultrasound. OUTCOMES The primary outcomes considered were improved (reduced and less intrusive) pain and improved (increased and easier) ranges of motion (ROM) of the adult cervical spine. EVIDENCE An “extraction” team recorded evidence from articles found by literature search teams using 4 separate literature searches, and rated it using a Table adapted from the Oxford Centre for Evidence-based Medicine. The searches were 1) Treatment; August, 2003, using MEDLINE, CINAHL, AMED, MANTIS, ICL, The Cochrane Library (includes CENTRAL), and EBSCO, identified 182 articles. 2) Risk management (adverse events); October, 2004, identified 230 articles and 2 texts. 3) Risk management (dissection); September, 2003, identified 79 articles. 4) Treatment update; a repeat of the treatment search for articles published between September, 2003 and November, 2004 inclusive identified 121 articles. VALUES To enable the search of the literature, the authors (Guidelines Development Committee [GDC]) regarded chiropractic treatment as including elements of “conservative” care in the search strategies, but not in the consideration of the range of chiropractic practice. Also, knowledge based only on clinical experience was considered less valid and reliable than good-caliber evidence, but where the caliber of the relevant evidence was low or it was non-existent, unpublished clinical experience was considered to be equivalent to

  15. Caught in the crosshairs: identity and cultural authority within chiropractic.

    PubMed

    Villanueva-Russell, Yvonne

    2011-06-01

    In this paper the discourse over identity and cultural authority within the profession of chiropractic in the United States has been analyzed using critical discourse analysis. As the profession struggles to construct one singular image, versions of self must be internally debated and also shaped in consideration of larger, external forces. The dilemma of remaining tied to a marginal professional status must be balanced against considerations of integration. Written texts from chiropractic journals and newspapers are analyzed in a multidimensional approach that considers the rhetorical devices and thematic issues of identity construction; the representation of various voices within the discourse (both heard and unheard); and the extent to which external pressures affect the projection of cultural authority for the profession. A heterogeneous discourse characterized by conflict was found, with discrepancies between everyday chiropractors in actual practice versus academic chiropractors and leaders particularly over the idea, practice and significance of science for the profession.

  16. Morris Fishbein, M.D.: the "medical Mussolini" and chiropractic.

    PubMed

    Donahue, J H

    1996-06-01

    Morris Fishbein, M.D. is the most important non-chiropractor to influence the chiropractic profession. From his post as editor and secretary of the American Medical Association, his anti-chiropractic writings, speeches and political activities had a profound effect on the profession's development. Because he was not only the foremost medical politician of the time, but also perceived as a multi-faceted author on public health issues, his credibility was high across large sections of the population and in most social institutions. His tactics and stature undoubtedly helped keep the profession limited to caring for a small percentage of the population. Because of him, chiropractors devised survival strategies that continue to influence the profession even today.

    2011-01-01

    Objective The purpose of this article is to trace the foundations of DD Palmer's sense of self and philosophy of chiropractic to its sources in modern Western philosophy as well as current metatheories about modernity. Discussion DD Palmer's sense of self was indicative of a modern self. A modern self is characterized as a self that developed after the Western Enlightenment and must come to terms with the insights of modernity such as Cartesian dualism, Spinoza's substance, Rousseau's expressivism, and Kant's critiques. It is argued that Palmer's philosophy can be viewed as part of the this tradition alongside his involvement in the 19th century American metaphysical religious culture, which was itself a response to these challenges of the modern self of modernity. Conclusion Palmer's development of chiropractic and its philosophy was a reaction to the challenges and promises of modernity. PMID:22693479

  19. Chiropractic treatment of low back pain: a prospective survey.

    PubMed

    Bronfort, G

    1986-06-01

    The clinical course of low back pain (LBP) during chiropractic treatment has not previously been reported on the basis of a prospective survey. The prospective survey is based on patient questionnaires filled in before treatment was started, as well as 1, 3, 6 and 12 months later. Clinical examination was performed at entry and also 1 month later. Two hundred ninety-eight patients with acute or chronic LBP from ten different chiropractic clinics were selected sequentially for this study. At the time of first contact between these patients and the clinics, the current episode of LBP had lasted less than 1 wk in 30% of the patients and for more than 4 wk in 51%. Sixty-five percent had radiating pain into the lower extremity, and 38% were unable to work. Fifty-three percent of the patients had consulted a medical doctor or had received other types of treatment due to the current episode. Nineteen percent were referred by a medical doctor to the chiropractor. After each period of registration, approximately 75% of the patients reported being free of symptoms or feeling much better. The present study was designed to be compared to a similar investigation carried out in a general medical practice. A clear indication of a more favorable outcome was found in those patients receiving chiropractic treatment when compared to those receiving medical treatment, especially concerning such factors as ability to work, bedrest and use of medication. Only a randomized controlled clinical trial is suited for a direct comparison of the effect and cost of chiropractic and medical treatment of LBP.

    This paper provides a cursory overview of attempts to discover, preserve and disseminate the history of the chiropractic profession, up to and including the organization of the Association for the History of Chiropractic (AHC). A surprisingly wide range of materials have been available for many decades, but sustained efforts at historical scholarship are more recent (past quarter century). The quality of these works has been uneven, but has improved with the emergence of chiropractic scholarly periodicals and interest from non-chiropractor investigators. Affiliates of the American-based AHC are located in Australia and Canada; organized historical scholarship in other regions of the world has yet to develop. Several substantial archival resources for historical investigations are available, and merit greater scrutiny and support within the profession.

    In a previous article, the author discussed current trends in utilization rates of chiropractic “Name Techniques” in Canada, and provided recommendations for their inclusion into the curriculum at the Canadian Memorial Chiropractic College. In this article, a review of the literature on “Name Techniques” was conducted, with interpretation and synthesis by the author. One hundred and eleven articles were found. These were: technique discussions (N = 39), case studies (N = 25), case series (N = 5), experimental studies (N = 25) and clinical trials (N = 17). The literature suggested that prone leg length testing and some x-ray mensurations may have acceptable inter and intra-rater reliability. In addition, there are several case studies that reported significant clinical benefits by patients receiving Activator, Alexander, and Upper Cervical treatments. Patients also reported improvements in quality of life while under either Upper Cervical or Network Spinal Analysis care. This information may help develop professional practice guidelines, and it may have implications for chiropractic research and education. Imagesp99-a

    Integrative medicine (IM) is a subset of interprofessional health care that seeks to join the knowledge and practices of various allopathic and complementary and alternative medicine disciplines in an attempt to offer cost-effective and clinically significant healthcare options for persons with acute or chronic illnesses. Although touted as a means for improving health outcomes and patient satisfaction while possibly lowering costs, further scientific evidence regarding the utility of IM approaches to health services delivery is needed. Collaborative Care for Older Adults (COCOA) is a chiropractic demonstration project that brings together an interdisciplinary team of researchers and clinicians from the Palmer Center for Chiropractic Research, Genesis Quad Cities Family Practice Residency, The University of Iowa, and Thomas Jefferson University to study the impact of a model of interprofessional education on geriatric health care. The Health Resources and Services Administration funded COCOA in 2009 to further develop and assess a patient-centered care model for the treatment of low back pain in older adults that uses a team-based approach between medical doctors and doctors of chiropractic.

  3. Chiropractic at the crossroads or are we just going around in circles?

    PubMed Central

    2011-01-01

    Background Chiropractic in Australia has seen many changes over the past 30 years. Some of these changes have advanced the professional status of chiropractic, improved undergraduate training and paved the way for a research culture. Unfortunately, other changes or lack of changes, have hindered the growth, public utilisation and professional standing of chiropractic in Australia. This article explores what influences have impacted on the credibility, advancement and public utilisation of chiropractic in Australia. Discussion The 1970's and 1980's saw a dramatic change within the chiropractic profession in Australia. With the advent of government regulation, came government funded teaching institutions, quality research and increased public acceptance and utilisation of chiropractic services. However, since that time the profession appears to have taken a backward step, which in the author's opinion, is directly linked to a shift by sections of the profession to the fundamentalist approach to chiropractic and the vertebral subluxation complex. The abandonment, by some groups, of a scientific and evidenced based approach to practice for one founded on ideological dogma is beginning to take its toll. Summary The future of chiropractic in Australia is at a crossroads. For the profession to move forward it must base its future on science and not ideological dogma. The push by some for it to become a unique and all encompassing alternative system of healthcare is both misguided and irrational. PMID:21599991

    Objective: The purpose of this study was to assess nurse practitioner (NP) and physician assistant (PA) students' views of chiropractic. As the role of these providers progresses in primary care settings, providers' views and knowledge of chiropractic will impact interprofessional collaboration and patient outcomes. Understanding how NP and PA students perceive chiropractic may be beneficial in building integrative health care systems. Methods: This descriptive quantitative pilot study utilized a 56-item survey to examine attitudes, knowledge, and perspectives of NP and PA students in their 2nd year of graduate studies. Frequencies and binomial and multinomial logistic regression models were used to examine responses to survey totals. Results: Ninety-two (97%) students completed the survey. There were conflicting results as to whether participants viewed chiropractic as mainstream or alternative. The majority of participants indicated lack of awareness regarding current scientific evidence for chiropractic and indicated a positive interest in learning more about the profession. Students who reported prior experience with chiropractic had higher attitude-positive responses compared to those without experience. Participants were found to have substantial knowledge deficits in relation to chiropractic treatments and scope of practice. Conclusion: The results of this study emphasize the need for increased integrative initiatives and chiropractic exposure in NP and PA education to enhance future interprofessional collaboration in health care.

    Objective The purpose of this commentary is to discuss potential 5 factors within straight chiropractic philosophy and practice that may prevent Medicare compliance. Discussion The national Medicare Benefit Policy Manual and the Florida Local Coverage Determination were reviewed to identify documentation and conceptual issues regarding chiropractic practice. Five Medicare positions were contrasted with tenets of straight chiropractic philosophy. Based on Medicare’s documentation requirements, Medicare defines subluxation and chiropractic practice from the perspective of treating spinal pain and related functional disability. In contrast, traditional straight chiropractic philosophy is not based on the treatment of spinal pain and disability or other symptomatic presentations. In this context, 5 potential areas of conflict are discussed. Conclusion The Medicare version of chiropractic practice is not consistent with traditional straight chiropractic philosophy, which may play a role in preventing Medicare compliance. The chiropractic profession may need to consider the fashion in which “philosophy” as it relates to technique and practice is presented to students and doctors to facilitate compliance with the documentation requirements of Medicare.

    Background Whether availability of chiropractic care affects use of primary care physician (PCP) services is unknown. Methods We performed a cross-sectional study of 17.7 million older adults who were enrolled in Medicare from 2010 to 2011. We examined the relationship between regional supply of chiropractic care and PCP services using Spearman correlation. Generalized linear models were used to examine the association between regional supply of chiropractic care and number of annual visits to PCPs for back and/or neck pain. Results We found a positive association between regional supply of chiropractic care and PCP services (rs = 0.52; P <.001). An inverse association between supply of chiropractic care and the number of annual visits to PCPs for back and/or neck pain was apparent. The number of PCP visits for back and/or neck pain was 8% lower (rate ratio, 0.92; 95% confidence interval, 0.91–0.92) in the quintile with the highest supply of chiropractic care compared to the lowest quintile. We estimate chiropractic care is associated with a reduction of 0.37 million visits to PCPs nationally, at a cost of $83.5 million. Conclusions Greater availability of chiropractic care in some areas may be offsetting PCP services for back and/or neck pain among older adults. (J Am Board Fam Med 2015;28:000–000.) PMID:26152439

    Objective: The objective of this study was to determine the attitudes of clinical faculty during the 2009–2010 academic year at the Canadian Memorial Chiropractic College towards the treatment of various non-musculoskeletal disorders. Methods: A confidential survey was distributed to the clinical faculty via email. It consisted of several questions polling the demographic of the respondent such as years in clinical practice, and a list of 29 non-musculoskeletal conditions. Clinicians were asked to indicate their opinions on each condition on rating scale ranging from strongly agree to strongly disagree. Results: Twenty of 22 clinicians responded. The conditions garnering the greatest positive ratings include: asthma, constipation, chronic pelvic pain, dysmenorrhea, infantile colic, and vertigo. The options regarding vertigo and asthma, while demonstrating an overall positive attitude towards the benefits of chiropractic care, were stratified amongst clinicians with varying years in clinical practice. Conclusion: This study suggests clinicians at this college are moderately open towards the chiropractic treatment of some non-musculoskeletal disorders. PMID:21629463

  9. The Five Eras of Chiropractic & the future of chiropractic as seen through the eyes of a participant observer

    PubMed Central

    2012-01-01

    Chiropractic has endured a turbulent history, marked by tremendous advances in areas such as education and licensing while marred by interprofessional conflict and a poor public image. The prolonged interprofessional conflict was instrumental in shaping the culture of chiropractic. These obstacles have long-since been removed although there are lingering effects from them. This article examines the chiropractic profession's history by dividing it into five Eras and suggests that there are three options available for the future of the profession. One: maintaining the status quo. Two: uniting under an evidence based scientific approach as partners in the health care delivery system that has buried the "one-cause, one-cure" sacred cow. The steps required to achieve this outcome are outlined. Three: openly dividing the profession into evidence based practitioners and subluxation based practitioners. Adopting this option would allow each branch of the profession to move forward in the health care delivery system unhindered by the other. It is unclear which option the profession will choose and whether the profession is mature enough to follow option two remains to be seen. What is evident is that the time to act is now.

    Objective To assess the significance of adverse events after spinal manipulation therapy (SMT) by replicating and critically reviewing a paper commonly cited when reviewing adverse events of SMT as reported by Ernst (J Roy Soc Med 100:330–338, 2007). Method Replication of a 2007 Ernst paper to compare the details recorded in this paper to the original source material. Specific items that were assessed included the time lapse between treatment and the adverse event, and the recording of other significant risk factors such as diabetes, hyperhomocysteinemia, use of oral contraceptive pill, any history of hypertension, atherosclerosis and migraine. Results The review of the 32 papers discussed by Ernst found numerous errors or inconsistencies from the original case reports and case series. These errors included alteration of the age or sex of the patient, and omission or misrepresentation of the long term response of the patient to the adverse event. Other errors included incorrectly assigning spinal manipulation therapy (SMT) as chiropractic treatment when it had been reported in the original paper as delivered by a non-chiropractic provider (e.g. Physician). The original case reports often omitted to record the time lapse between treatment and the adverse event, and other significant clinical or risk factors. The country of origin of the original paper was also overlooked, which is significant as chiropractic is not legislated in many countries. In 21 of the cases reported by Ernst to be chiropractic treatment, 11 were from countries where chiropractic is not legislated. Conclusion The number of errors or omissions in the 2007 Ernst paper, reduce the validity of the study and the reported conclusions. The omissions of potential risk factors and the timeline between the adverse event and SMT could be significant confounding factors. Greater care is also needed to distinguish between chiropractors and other health practitioners when reviewing the application of SMT

    Objectives: To investigate the degree of knowledge chiropractic fourth year interns and post-graduate chiropractic residents have in regard to concussion diagnosis and management. Methods: A survey modified from a study conducted by Boggild and Tator (2012), was administered to fourth year chiropractic interns and post-graduate residents via SurveyMonkey.com. Results: Chiropractic fourth year interns and postgraduate chiropractic specialty college residents scored 5.2 and 5.25 out of 9 respectively, which compares well with Bogglid and Tator’s reports on medical students and residents. Several knowledge gaps were identified in the sample population. Conclusion: The results from this survey show that the concussion knowledge among Canadian fourth year chiropractic interns and specialty college residents compares favorably with the knowledge of fourth year medical students and residents in diagnosing and managing concussions. Chiropractors appear to possess the skills and knowledge to diagnose and manage concussion equal to their medical counterparts. However, knowledge gaps regarding concussion diagnosis and management were found among chiropractic students and residents. PMID:28065987

    Tardive dyskinesia (TD) is an umbrella term typically used to describe a movement disorder associated with the use of neuroleptic (anti-psychotic) medication. It is characterized by abnormal, repetitive and involuntary movements. The movements may be around the mouth and face (orofacial dyskinesia) and less frequently, in the trunk and limbs (trunk and limb dyskinesia). TD occurs in over 20% of those using neuroleptic medication continually for longer than three months. A case report is presented of a patient affected by TD who suffered mechanical musculoskeletal pain secondary to its effects, and was managed by chiropractic care. PMID:17549198

    In this paper, the argument will be made that present day “chiropractic philosophy” must be rejected as a professional obstacle. It is an unscientific relic of D.D. Palmer’s personal religious beliefs. A philosophy of chiropractic can only emerge from the application of philosophy of science to our scientific and clinical practices. This new philosophy should incorporate the general healing perspective of the ancient Coan tradition which will be described. This perspective can be made distinctively chiropractic by a synthesis with D.D. Palmer’s principle of Tone. Discussion will focus on how our philosophy can be developed to guide us into the 21st century.

    Objective: The purpose of this study was to evaluate the effectiveness of different reported methods used to teach spinal manipulative therapy to chiropractic students. Methods: For this best-evidence literature synthesis, 5 electronic databases were searched from 1900 to 2015. Eligible studies were critically appraised using the criteria of the Scottish Intercollegiate Guidelines Network. Scientifically admissible studies were synthesized following best-evidence synthesis principles. Results: Twenty articles were critically appraised, including 9 randomized clinical trials, 9 cohort studies, and 2 systematic reviews/meta-analyses. Eleven articles were accepted as scientifically admissible. The type of teaching method aids included a Thrust in Motion cervical manikin, instrumented cardiopulmonary reanimation manikin, padded contact with a load cell, instrumented treatment table with force sensor/transducer, and Dynadjust instrument. Conclusions: Several different methods exist in the literature for teaching spinal manipulative therapy techniques; however, future research in this developing area of chiropractic education is proposed. It is suggested that various teaching methods be included in the regular curricula of chiropractic colleges to aid in developing manipulation skills, efficiency, and knowledge of performance.

    2013-01-01

    Objective Blood pressure measurement is a basic clinical procedure. However, studies have shown that many errors are made when health care providers acquire blood pressure readings. Our study assessed knowledge of blood pressure measurement procedures in chiropractic students. Methods This was an observational, descriptive study. A questionnaire based on one created by the American Heart Association was given to 1st, 2nd, 3rd, and final year students (n = 186). A one way ANOVA was used to analyze the data. Results Of the students 80% were confident that their knowledge of this clinical skill was adequate or better. However, the overall score on the knowledge test of blood pressure–taking skills was 52% (range, 24%–88%). The only significant difference in the mean scores was between the 1st and 2nd year students compared to the 3rd and 4th year students (p < .005). Of the 16 questions given, the following mean scores were: 1st year 10.45, 2nd year 9.75, 3rd year 7.93, and 4th year 8.33. Of the 16 areas tested, 10 were of major concern (test item score <70%), showing the need for frequent retraining of chiropractic students. Conclusion Consistent with studies in other health care disciplines, our research found the knowledge of blood pressure skills to be deficient in our sample. There is a need for subsequent training in our teaching program. PMID:23957320

    Objective: The purpose of this study was to measure chiropractic student attitudes toward team-based learning (TBL) to determine if they are similar to those of medical students and to help clarify existing evidence regarding student perceptions of TBL. Method: Two consecutive cohorts of chiropractic students enrolled in a course that used weekly TBL activities completed an adaptation of the value of teams survey at the end of the term. Chi square analysis was used to assess for differences in scores between the beginning and end of the term. Results: The students did value the TBL process (χ2 = 75.21, p < .001). Students had a neutral opinion regarding TBL at the start of the term (χ2 = 30.41, p < .001), but their opinion of TBL improved by the end of the term (χ2 = 51.66, p < .001). Conclusion: These results were similar to those found in medical education studies. Students tended to value TBL, but they were more receptive to it over time. PMID:27439766

  1. Chiropractic: from rejection to acceptance 1900-1980

    This paper presents some of the significant milestones that were reached in the long struggle from rejection to acceptance. While it does not attempt to include all of the historical events which contributed to this evolutionary process, it does identify some of the key elements in the laying of a sound foundation upon which the profession could continue to build. It is hoped that other papers will be written to add to our understanding of this important era in chiropractic’s early development. The years from 1917-1958 deal mainly with medicine’s intransigent opposition; then the tide began to turn in chiropractic’s favour. Governments appointed commissions of enquiry to bring some order into the health care field. Our profession’s brief to the Royal Commission on Health Services was described by the Minister of National Health and Welfare as “a very powerful document”. The government enquiries, in addition to identifying professional weaknesses, also made favourable recommendations which encouraged the further growth and development of chiropractic. Commenting on his work as a Royal Commissioner, Mr. Justice Gerard Lacroix said that the medical opposition to chiropractic was: “... based on bias and prejudice, ignorance and refusal to learn about chiropraxy. I thought it safer to know and understand before judging” (p. 13).8

    1997-01-01

    Objective: To establish a data bank which will serve as a comprehensive inventory of data and document practical information on Canada’s licensed chiropractors and to produce a summary report of this information. Design: A national census mail survey. Setting: Canada. The survey administration timeline during which information was collected was the period of August 1995 to July 1996. Participants: All chiropractors licensed to practice chiropractic in Canada, excluding chiropractors practising in the Yukon and Northwest Territories. A total of 4,246 questionnaires were mailed, of which 121 were ineligible. There were 2,905 valid responses (response rate 70.4%). Main outcome measures: Background information (demographics), professional activity, educational, training and affiliations, practice characteristics, finances and income. Results: Background information: 82.8% of all respondents were male. On January 1, 1997, the mean age of all respondents was 41.9 years. 88.6% of all respondents were born in Canada and 74.8% graduated from the Canadian Memorial Chiropractic College. The mean number of years in practice by all respondents was 13.7 years. 17.5% of all respondents had more than one practice location. Professional activity: A total of 96.2% of the respondents were active chiropractors (a chiropractor in active practice was one whose level of activity was self-described as full-time, part-time or semi-retired and who was in practice at least 10 hours per week). 85% reported being in full-time practice, 8.7% in part-time practice and 2.5% reported being semi-retired. Full-time chiropractors reported working on average 41.3 hours per week, 49.1 weeks per year and receiving 158.6 total patient visits per week. Active chiropractors reported spending on average 75.1% of their work time on direct patient care. 39.6% of active chiropractors reported that their practice had decreased over the last three years (in terms of number of patient visits).

    Objective The purpose of this study is to describe chiropractic treatment of 14 patients who presented with signs and symptoms of temporomandibular joint dysfunction (TMD). Methods This is a retrospective case series of 14 patients, including 13 adults and 1 child. The majority of these patients were undergoing chiropractic care for spine-related conditions when they presented with additional TMD signs and symptoms. They were evaluated and treated with Activator Methods International published protocols relative to the temporomandibular joint before the addition of treatment to the suprahyoid muscles. Results All pre- and postadjustment assessments were recorded using a numeric pain scale. The resulting average showed a reduction in the patients’ pain scores from the initial visit of 8.3 ± 1.6 to the last visit at 1.4 ± 1.1 with an 80.9% ± 15.4% improvement. The average number of visits was 13.6 ± 8.2. Conclusion All patients selected for this case series showed a reduction of temporomandibular dysfunction symptoms. PMID:26793040

    Objective The purpose of this study was to track the graduates of the Los Angeles College of Chiropractic (LACC) radiology residency program, review their scholarly productivity, and report those involved in teaching and leadership positions. Methods Former LACC residents’ career information was identified through publicly available electronic documents including Web sites and social media. PubMed and the Index to Chiropractic Literature databases were searched for chiropractic graduate job surveys, and proportional comparisons were made between the career paths of LACC radiology residency graduates and those of non–residency-trained chiropractors. Results Of 47 former LACC residents, 28 (60%) have or previously had careers in tertiary (chiropractic) education; and 12 (26%) have attained a department chair position or higher at tertiary teaching institutions. Twenty-two (47%) have or previously had private radiology practices, whereas 11 (23%) have or previously had clinical chiropractic practices. Often, residency graduates hold or have held 2 of these positions at once; and one, all 3. Chapters or books were authored by 13 (28%). Conclusion Radiology residency LACC graduates are professionally active, particularly in education, and demonstrate scholarly productivity. PMID:23966885

    Objective The purpose of this article is to report the response of chiropractic care of a geriatric veteran with degenerative disk disease and diffuse idiopathic skeletal hyperostosis. Clinical Features A 74-year-old man presented with low back pain (LBP) and loss of feeling in his lower extremities for 3 months. The LBP was of insidious onset with a 10/10 pain rating on the numeric pain scale (NPS) and history of degenerative disk disease and diffuse idiopathic skeletal hypertrophy. Oswestry questionnaire was 44% and health status questionnaire was 52%, which were below average for his age. The patient presented with antalgia and severe difficulty with ambulation and thus used a walker. Intervention and Outcome Chiropractic care included Activator Methods protocol. Two weeks into treatment, he reported no back pain; and after 4 treatments, he was able to walk with a cane instead of a walker. The NPS decreased from a 10/10 to a 0/10, and his Revised Oswestry score decreased from 44/100 to 13.3/100. His Health Status Questionnaire score increased 25 points to 77/100, bringing him from below average for his age to above average for his age. Follow-up with the patient at approximately 1 year and 9 months showed an Oswestry score of 10/100 and a Health Status Questionnaire score of 67/100, still above average for his age. Conclusion The findings in this case study showed that Activator-assisted spinal manipulative therapy had positive subjective and objective results for LBP and ambulation in a geriatric veteran with degenerative disk disease and diffuse idiopathic skeletal hyperostosis.

    1997-01-01

    Current provincial legislation in various jurisdictions across Canada, serves to impede the utilization of the diagnostic laboratory by doctors of chiropractic. Chiropractic students both in Canada and the United States, are required to successfully complete an intensive course of study in the area of laboratory diagnosis, as a necessary aspect of the undergraduate educational curriculum. Unfortunately, Canadian graduate doctors of chiropractic and their patients, are not currently afforded the privilege of direct referral to a community diagnostic laboratory. Rather, chiropractors must enlist the assistance of other health care providers, namely medical doctors, to acquire various laboratory testing procedures. The premise of this paper is intended to demonstrate the necessity of revising such laws, in order to address the needs of those health care consumers who seek the services of the rapidly growing profession of chiropractic. Two clinical cases are presented as illustrative examples.

    2002-01-01

    Abstract Asthma is a multifactorial dysfunction of the respiratory system. Nutritional, environmental, genetic, and emotional factors all play animportant part in the etiology of this condition. One form of chiropractic, Sacro Occipital Technique (SOT), offers some conservative alternatives to the treatment of asthma. SOT expands the chiropractic armamentarium of techniques available, allowing methods putatively affecting the viscera, vertebra, post and preganglionic reflexes, as well as cranial and sacral influences on the primary respiratory mechanism. Though more research is needed to evaluate the efficacy of chiropractic care of asthma, the conservative nature of chiropractic care with its minimal side effects, warrants patient and a health practitioner's consideration prior to embarking on any course of treatment that might have serious side effects.

    Objective: Our purpose was to describe the financial knowledge, habits and attitudes of chiropractic students. Methods: We designed a cross-sectional survey to measure basic financial knowledge, current financial habits, risk tolerance, and beliefs about future income among 250 students enrolled in business courses at one US chiropractic college. Descriptive statistical analyses were performed. Results: We received 57 questionnaires (23% response rate). Most respondents would accumulate over $125,000 in student loan debt by graduation. Financial knowledge was low (mean 77%). Most respondents (72%) scored as average financial risk takers. Chiropractic students reported recommended short-term habits such as having checking accounts (90%) and health insurance (63%) or paying monthly bills (88%) and credit cards (60%). Few saved money for unplanned expenses (39%) or long-term goals (26%), kept written budgets (32%), or had retirement accounts (19%). Conclusion: These chiropractic students demonstrated inadequate financial literacy and did not engage in many recommended financial habits. PMID:24587498

    2000-06-01

    Today's National Chiropractic Mutual Insurance Company (NCMIC) evolved from the legal protective services offered initially by the Universal Chiropractors' Association, and subsequently, by the National Chiropractic Association (NCA). At first these services focused on the criminal defence of chiropractors charged with unlicensed practice. However, as an increasing number of jurisdictions enacted chiropractic statutes, the NCA's legal program became ever more involved in civil litigation: suits for malpractice and negligence. Steering the NCA throughout its tumultuous voyage was its longtime secretary-treasurer, Loran M. Rogers, D.C. When the NCA spun off its legal services division in 1946, forming the National Chiropractic Insurance Company (predecessor of the NCMIC), Rogers continued his work as executive secretary-treasurer of the malpractice insurer.

    A literature search and narrative review was carried out with the intent of determining the current level of knowledge regarding the chiropractic treatment of athletes for the purpose of sport performance enhancement. Of the fifty-nine relevant articles retrieved, only 7 articles of variable quality were obtained which specifically investigated/discussed chiropractic treatment and its involvement in sport performance enhancement. The role of the chiropractor in sport, unsubstantiated claims of performance enhancement, theories of how chiropractic treatment may influence sport performance, and the available evidence for the benefit of chiropractic treatment on sport performance are reviewed and discussed. Areas and directions for future studies are postulated. At this time there is insufficient evidence to convincingly support the notion that treatment provided by chiropractors can directly improve sport performance.

    This literature review examined studies that described practice, utilization, and policy of chiropractic services within military and veteran health care environments. A systematic search of Medline, CINAHL, and Index to Chiropractic Literature was performed from inception through April 2015. Thirty articles met inclusion criteria. Studies reporting utilization and policy show that chiropractic services are successfully implemented in various military and veteran health care settings and that integration varies by facility. Doctors of chiropractic that are integrated within military and veteran health care facilities manage common neurological, musculoskeletal, and other conditions; severe injuries obtained in combat; complex cases; and cases that include psychosocial factors. Chiropractors collaboratively manage patients with other providers and focus on reducing morbidity for veterans and rehabilitating military service members to full duty status. Patient satisfaction with chiropractic services is high. Preliminary findings show that chiropractic management of common conditions shows significant improvement.

    Objective The purpose of this case series is to describe findings for patients with bladder pain syndrome (BPS) or interstitial cystitis (IC) who responded positively under chiropractic care. Clinical Features Eight cases were selected retrospectively reviewed from 2 independent chiropractic clinics in Scotland. Cases were selected if patients reported bladder dysfunction problems and responded positively to chiropractic care. The cases in this report describe the range of patients affected by this condition. Each patient was treated using chiropractic methods that were specific to the individual case. Intervention and Outcomes The patients selected for this case series showed positive response to chiropractic care over various lengths of time and numbers of treatments. Some of the chiropractic patients who had chronic spinal conditions had reoccurrence of bladder symptoms during an exacerbation of mechanical spinal problems. Conclusion This case series highlights that bladder and urinary problems may be associated with spinal dysfunction for some patients. PMID:23843758

    We report on a 21-day-old infant with healing posterior rib fractures that were noted after a chiropractic visit for colic. Chiropractors are the third largest group of health care professionals in the United States, and colic is the leading complaint for pediatric chiropractic care. Rib fractures, specifically when posterior, are traditionally considered to be secondary to nonaccidental trauma. Thorough investigation is necessary to rule out bone fragility and genetic disorders, but patient history is key when evaluating unexplained fractures.

    Objective : We assessed the change in attitudes, knowledge, and perspectives of medical students towards chiropractic after a 1-hour educational intervention. Methods : A mixed-methods approach was used with a 52-item cross-sectional paper survey and 1 focus group of third-year medical students. The views of these medical students towards chiropractic were assessed previously in their second-year of medical school. ANOVA and the Wilcoxon rank-sum test were used to assess between-group differences between the medical students' views before and after the educational intervention. The constant comparative method for analyzing qualitative data was used to identify emergent themes from the focus group transcript. Results : Of 112 third-year medical students, 58 completed the survey (51.7% response rate). The focus group consisted of 6 medical students. Self-reported understanding of chiropractic and number of attitude-positive responses were significantly higher in the group after the educational session. The average number of correct responses assessing knowledge on chiropractic also was significantly higher. Focus group themes were that medical students wanted exposure to chiropractic in clinical settings, had negative attitudes towards chiropractic formed from hidden curriculum, had concerns regarding evidence and safety of chiropractic, and thought that timing of the session on chiropractic was too late in the curriculum. Conclusions : The attitudes and knowledge of medical students towards chiropractic improved immediately after a 1-hour educational intervention. Formally educating medical students on chiropractic may help minimize hidden curriculum issues regarding chiropractic, as identified by the medical students, and facilitate collaboration between medical and chiropractic providers.

    2010-01-01

    Background A great deal has been published in the chiropractic literature regarding the response, or lack thereof, of various common pediatric conditions to chiropractic care. The majority of that literature is of low scientific value (that is, case reports or case series). The purpose of this review is to summarize the literature from the point of view of clinicians, rather than researchers, and to discuss some additional detail of the conditions themselves. Methods Databases searched were PubMed, Mantis, Index to Chiropractic Literature, and CINAHL. Keywords were chiropractic paired with colic, crying infant, nocturnal enuresis, asthma, otitis media and attention deficit hyperactivity disorder. Results Most of the published literature centers around case reports or series. The more scientifically rigorous studies show conflicting results for colic and the crying infant, and there is little data to suggest improvement of otitis media, asthma, nocturnal enuresis or attention deficit hyperactivity disorder. Discussion The efficacy of chiropractic care in the treatment of non-musculoskeletal disorders has yet to be definitely proven or disproven, with the burden of proof still resting upon the chiropractic profession.

    Chiropractic is a complementary medicine that has been growing increasingly in different countries over recent decades. It addresses the prevention, diagnosis and treatment of the neuromusculoskeletal system disorders and their effects on the whole body health. This study aims to evaluate the effectiveness of chiropractic in the treatment of different diseases. To gather data, scientific electronic databases, such as Cochrane, Medline, Google Scholar, and Scirus were searched and all systematic reviews in the field of chiropractic were obtained. Reviews were included if they were specifically concerned with the effectiveness of chiropractic treatment, included evidence from at least one clinical trial, included randomized studies and focused on a specific disease. The research data including the article’s first author’s name, type of disease, intervention type, number and types of research used, meta-analysis, number of participants, and overall results of the study, were extracted, studied and analyzed. Totally, 23 chiropractic systematic reviews were found, and 11 articles met the defined criteria. The results showed the influence of chiropractic on improvement of neck pain, shoulder and neck trigger points, and sport injuries. In the cases of asthma, infant colic, autism spectrum disorder, gastrointestinal problems, fibromyalgia, back pain and carpal tunnel syndrome, there was no conclusive scientific evidence. There is heterogeneity in some of the studies and also limited number of clinical trials in the assessed systematic reviews. Thus, conducting comprehensive studies based on more reliable study designs are highly recommended. PMID:26448951

    Health practitioners work under fiduciary constraint, and are obligated to favour patient needs over all others and in particular their own. The principles of professionalism demand that professionals take great care to ensure that boundaries are maintained safely to provide an optimal setting in facilitating patient care. Boundary violations cause serious harm to the patient. Any romantic or sexual activity between parties is the most serious form of boundary violation. The chiropractic profession is included in the list of disciplines which are at an increased risk for boundary violations. The authors propose a four stage protocol which is designed to offer all parties maximal protection beginning with undergraduate professional education and then mandatory continuing education for registrants in professional practice. The protocol would affect all aspects of professional life including training in boundaries and jurisdictional regulation. PMID:22457543

    Objective The purpose of this article is to explore the postmodern, postrational, and postconventional core of DD Palmer's self-sense and philosophy. Discussion DD Palmer's self and philosophy can be viewed as a reaction to the self of modernity and its challenges of a fracture between mind and body, spirit, and nature. It is argued that Palmer's solution to these vexing problems facing the modern self was to use postrational and postconventional logic to overcome the dualisms. His philosophy resonates with similar postrational approaches, most notably, the German idealist Schelling. Conclusion It is argued that Palmer was one of the first postrational individuals in America and that chiropractic was an attempt at the first postrational health profession. PMID:22693480

    Objective The purpose of this case report is to describe a case in which early detection and proper follow-up of spontaneous vertebral artery dissection led to satisfactory outcomes. Clinical Features A 34-year old white woman reported to a chiropractic clinic with a constant burning pain at the right side of her neck and shoulder with a limited ability to turn her head from side to side, periods of blurred vision, and muffled hearing. Dizziness, visual and auditory disturbances, and balance difficulty abated within 1 hour of onset and were not present at the time of evaluation. A pain drawing indicated burning pain in the suboccipital area, neck, and upper shoulder on the right and a pins and needles sensation on the dorsal surface of both forearms. Turning her head from side-to-side aggravated the pain, and the application of heat brought temporary relief. The Neck Disability Index score of 44 placed the patient’s pain in the most severe category. Intervention and Outcome The patient was not treated on the initial visit but was advised of the possibility of a vertebral artery or carotid artery dissection and was recommended to the emergency department for immediate evaluation. The patient declined but later was convinced by her chiropractor to present to the emergency department. A magnetic resonance angiogram of the neck and carotid arteries was performed showing that the left vertebral artery was hypoplastic and appeared to terminate at the left posterior inferior cerebellar artery. There was an abrupt moderately long segment of narrowing involving the right vertebral artery beginning near the junction of the V1 and V2 segments. The radiologist noted a concern regarding right vertebral artery dissection. Symptoms resolved and the patient was cleared of any medications but advised that if symptoms reoccurred she was to go for emergency care immediately. Conclusion Recognition and rapid response by the chiropractic physician provided the optimum outcome for

    Objective: This study compared National Board of Chiropractic Examiners part I test scores between students who did and did not serve as tutors on the subject matter. Methods: Students who had a prior grade point average of 3.45 or above on a 4.0 scale just before taking part I of the board exams were eligible to participate. A 2-sample t-test was used to ascertain the difference in the mean scores on part I between the tutor group (n = 28) and nontutor (n = 29) group. Results: Scores were higher in all subjects for the tutor group compared to the nontutor group and the differences were statistically significant (p < .01) with large effect sizes. Conclusion: The tutors in this study performed better on part I of the board examination compared to nontutors, suggesting that tutoring results in an academic benefit for tutors themselves.

Because of the association between tobacco use and the health problems that may provoke referral to chiropractic care, doctors of chiropractic (DCs) may be able to give patients personalized proximal health feedback that may motivate them to quit. However, DCs have not been utilized in this role. The primary aim of this study was to design and refine a brief office-based tobacco intervention for use within chiropractic settings. Methods: This study was conducted in 20 private chiropractic practices in 2 phases: (a) intervention development, in which we created and focus tested practitioner and patient materials, and (b) feasibility, in which we evaluated the impact of the intervention on 210 tobacco-using chiropractic patients. Results: Analyses were conducted on 156 patients who exclusively smoked cigarettes. Using an intent-to-treat approach, assuming all nonresponders to be smokers, 13 (8.3%) reported 7-day abstinence at 6 weeks, 22 (14.1%) at the 6-month follow-up, and 35 (22.4%) at the 12-month assessment. Eleven participants (7.1%) reported prolonged abstinence at the 6-month follow-up, and 15 (9.6%) reported prolonged abstinence at 12 months. Conclusions: To our knowledge, this is the first study to refine a brief office-based treatment for tobacco dependence for use in chiropractic settings. The results of this study were promising and will lead to a randomized clinical trial. If found to be effective, this model could be disseminated to chiropractic practitioners throughout the United States. PMID:20097840

    Objective: Most studies on spinal manipulation learning demonstrate the relevance of including motor learning strategies in chiropractic curricula. Two outcomes of practice are the production of movement in an efficient manner and the improved capability of learners to evaluate their own motor performance. The goals of this study were to evaluate if expertise is associated with increased spinal manipulation proficiency and if error detection skills of force application during a high-velocity low-amplitude spinal manipulation are related to expertise. Methods: Three groups of students and 1 group of expert chiropractors completed 10 thoracic spine manipulations on an instrumented device with the specific goal of reaching a maximum peak force of 300 N after a brief period of practice. After each trial, participants were asked to give an estimate of their maximal peak force. Force-time profiles were analyzed to determine the biomechanical parameters of each participant and the participant's capacity to estimate his or her own performance. Results: Significant between-group differences were found for each biomechanical parameter. No significant difference was found between groups for the error detection variables (p > .05). The lack of significant effects related to the error detection capabilities with expertise could be related to the specificity of the task and how the training process was structured. Conclusion: This study confirms that improvements in biomechanical parameters of spinal manipulation are related to expertise. Feedback based on error detection could be implemented in chiropractic curricula to improve trainee abilities in detecting motor execution errors. PMID:26270897

    Objective To investigate the motivations, challenges and perceptions of the educational environment of emerging researchers in chiropractic. Methods A descriptive web-based survey of higher-degree chiropractic research students was performed between October and November 2013. The survey consisted of open and closed questions and the Dundee Ready Education Environment Measure. Results Twenty-two students currently enrolled in a higher-degree research program participated. Students were most commonly enrolled in a doctor of philosophy program at a part-time rate. Motivations of research were desire to improve the clinical care aspects of chiropractic for the public and belief that chiropractic research is lacking. The greatest challenges were the negative attitudes towards chiropractic, finding enough time to do everything required, and feelings of isolation. The higher-degree research educational environment was perceived to be more positive than negative, with the stimulating nature of research a positive feature. A negative feature of the educational environment was poor undergraduate preparation for higher-degree research. Conclusion This study is the first study to describe higher-degree chiropractic research students. Primary motivations included building research, while challenges included not only negative attitudes toward the chiropractic profession but also negative attitudes toward researchers from within the profession. The higher-degree research educational environment was perceived to be positive. By acknowledging the issues that surround emerging researchers in chiropractic, the profession is better placed to foster academics and build research capacity. PMID:26090697

    The differential diagnosis for ischemic central nervous system infarcts in young patients includes paradoxic emboli through cardiac shunts, vasculitis, and vascular trauma. We report a young woman who developed headache, vomiting, diplopia, dizziness, and ataxia following neck manipulation by her chiropractor. A computed tomography scan of the head revealed an infarct in the inferior half of the left cerebellar hemisphere and compression of the fourth ventricle causing moderate acute obstructive hydrocephalus. Magnetic resonance angiography revealed severe narrowing and low flow in the intracranial segment of the left distal vertebral artery. The patient was treated with mannitol and a ventriculostomy and had an excellent functional recovery. This report illustrates the potential hazards associated with neck trauma, including chiropractic manipulation. The vertebral arteries are at risk for aneurysm formation and/or dissection, which can cause acute stroke. PMID:25552813

  12. Chiropractic care for paediatric and adolescent Attention-Deficit/Hyperactivity Disorder: A systematic review

    PubMed Central

    2010-01-01

    Background Psychostimulants are first line of therapy for paediatric and adolescent AD/HD. The evidence suggests that up to 30% of those prescribed stimulant medications do not show clinically significant outcomes. In addition, many children and adolescents experience side-effects from these medications. As a result, parents are seeking alternate interventions for their children. Complementary and alternative medicine therapies for behavioural disorders such as AD/HD are increasing with as many as 68% of parents having sought help from alternative practitioners, including chiropractors. Objective The review seeks to answer the question of whether chiropractic care can reduce symptoms of inattention, impulsivity and hyperactivity for paediatric and adolescent AD/HD. Methods Electronic databases (Cochrane CENTRAL register of Controlled Trials, Cochrane Database of Systematic reviews, MEDLINE, PsycINFO, CINAHL, Scopus, ISI Web of Science, Index to Chiropractic Literature) were searched from inception until July 2009 for English language studies for chiropractic care and AD/HD. Inclusion and exclusion criteria were applied to select studies. All randomised controlled trials were evaluated using the Jadad score and a checklist developed from the CONSORT (Consolidated Standards of Reporting Trials) guidelines. Results The search yielded 58 citations of which 22 were intervention studies. Of these, only three studies were identified for paediatric and adolescent AD/HD cohorts. The methodological quality was poor and none of the studies qualified using inclusion criteria. Conclusions To date there is insufficient evidence to evaluate the efficacy of chiropractic care for paediatric and adolescent AD/HD. The claim that chiropractic care improves paediatric and adolescent AD/HD, is only supported by low levels of scientific evidence. In the interest of paediatric and adolescent health, if chiropractic care for AD/HD is to continue, more rigorous scientific research needs to

    Objective The aims of our study were to measure the learning style preferences of chiropractic students and to assess whether they differ across the 5 years of chiropractic study. Methods A total of 407 (41.4% females) full-degree, undergraduate, and postgraduate students enrolled in an Australian chiropractic program agreed to participate in a cross-sectional survey comprised of basic demographic information and the Visual, Aural, Read/Write, Kinesthetic (VARK) questionnaire, which identifies learning preferences on four different subscales: visual, aural, reading/writing, and kinesthetic. Multivariate analysis of variance and the χ2 test were used to check for differences in continuous (VARK scores) and categorical (VARK category preference) outcome variables. Results The majority of chiropractic students (56.0%) were found to be multimodal learners. Compared to the other learning styles preferences, kinesthetic learning was preferred by a significantly greater proportion of students (65.4%, p < .001) and received a significantly greater mean VARK score (5.66 ± 2.47, p < .001). Conclusions To the best of our knowledge, this is the first time chiropractic students have been shown to be largely multimodal learners with a preference for kinesthetic learning. While this knowledge may be beneficial in the structuring of future curricula, more thorough research must be conducted to show any beneficial relationship between learning style preferences and teaching methods.

    Introduction: The purpose of this article was to perform a narrative review of the chiropractic literature regarding older patients between 2001 and 2010. Methods: A three step search strategy of the literature involved electronic searching, hand searching and reference tracking. Results: One hundred and eighty eight articles germane to chiropractic geriatric practice and education were retrieved. Discussion: Compared to the review of the literature conducted prior to 2000, the number of references on chiropractic geriatric education increased from 3 to 11, the number of demographic studies increased from 9 to 18, the number of case reports increased from 25 to 83, the number of clinical trials increased from 4 to 21 (only two RCTs found) and the number of references on clinical guidelines and general clinical information increased from 18 to 55. Conclusion: This review found 188 retrievable articles available to practitioners to effectively care plan for their older patients, a better than three fold increase in the number of references found during a similar review conducted at the end of the previous decade. However, there is clearly a gap in the evidence base of chiropractic geriatric care, particularly the under-representation of clinical trials of all kinds involving older chiropractic patients.

    [Purpose] The purpose of this study was to examine whether chiropractic techniques would reduce the curvature of idiopathic scoliosis, which commonly occurs in elementary school children. [Subjects] The subjects of this study were 5 healthy elementary students who listened to an explanation of the study methods and purpose of the study and agreed to participate in the experiment. [Methods] The Cobb angle was measured by taking an X-ray (FCT-1, Dongmun, Goyangsi, Republic of Korea) taken from the rear, using X-ray film. The method of intervention this study used was application of chiropractic techniques. Spinal correction was carried out for 30 minutes per session, which included soft tissue massage, 3 times a week for 8 weeks. [Results] It was established that the Cobb angle was noticeably decreased after 4 weeks of the intervention. Post Hoc analysis revealed that the Cobb angle noticeably decreased after 4 weeks compared with the Cobb angle before the chiropractic techniques were applied. However, no significant difference in Cobb angle was evident after the fourth week. [Conclusion] This study demonstrated that chiropractic techniques can effectively reduce the Cobb angle within as little as 4 weeks. So, we can confirm that the chiropractic techniques were effective for reducing the curvature of idiopathic scoliosis.

    Purpose: One important objective of chiropractic education is to foster student professional confidence and competence in patient communication and clinical skills. Therefore, the aim of this article is to review the extant literature on this topic, stressing the significance of building students' confidence for effective practice and the need for more research in this area. Methods: The authors reviewed MEDLINE and ERIC from 1980 through 2008 using several key words pertinent to confidence and health care. Three distinct, but interrelated, bodies of literature were assessed, including professional confidence in health care research, the nature and development of confidence in educational psychology research, and fostering professional confidence in chiropractic education. Results: It was apparent through the review that chiropractic education has developed educational methods and opportunities that may help develop and build student confidence in patient communication and clinical skills. However, there has not been sufficient research to provide empirical evidence of the impact. Conclusion: Fostering chiropractic students' development of confidence in what they say and do is of paramount importance not only to them as new practitioners but more importantly to the patient. There is no doubt that a better understanding of how confidence can be developed and consolidated during tertiary study should be a major goal of chiropractic education PMID:19826543

    Introduction The use of rehabilitation services to address musculoskeletal, neurological and cardiovascular late effects among childhood cancer survivors could improve physical function and health-related quality-of-life (HRQL). We describe physical therapy (PT) and chiropractic utilization among childhood cancer survivors and their association with HRQL. Methods The sample included 5+ year survivors from the Childhood Cancer Survivor Study (N=9,289). Questions addressing use of PT or chiropractic services and HRQL (Medical Outcomes Survey Short Form (SF-36)) were evaluated. Multivariable regression models compared PT and/or chiropractic utilization between survivors and siblings, and by diagnosis, treatment and demographic characteristics; associations between chronic disease, PT/chiropractic use, and HRQL were similarly evaluated. Results Survivors were not more likely to use PT (OR 1.0; 95% CI 0.8-1.2) or chiropractic (OR 0.8; 95% CI 0.7-1.0) services than siblings. More survivors reported using chiropractic (12.4%) than PT (9.2%) services. Older age and having health insurance were associated with utilization of either PT or chiropractic services. Grade 3-4 chronic conditions and a CNS tumor or sarcoma history were associated with PT but not with chiropractic service utilization. Survivors with musculoskeletal (OR 1.8; 95% CI 1.1-2.9), neurological (OR 3.4; 95% CI 1.6-6.9), or cardiovascular (OR 3.3; 95% CI 1.6-6.9) chronic conditions who used PT/chiropractic services were more likely to report poor physical health than survivors who did not use services. Conclusions The reported prevalence of PT/chiropractic among survivors is consistent with that reported by siblings. Severity of late effects is associated with service use and with reporting poor physical health. Implications for Cancer Survivors Long-term childhood cancer survivors do not appear to utilize rehabilitation services to optimize physical function and support increased HRQL. PMID:20922492

    Objective The purpose of this study was to determine whether use of chiropractic manipulative treatment (CMT) was associated with lower healthcare costs among multiply-comorbid Medicare beneficiaries with an episode of chronic low back pain (cLBP). Methods We conducted an observational, retrospective study of 2006–2012 Medicare fee-for-service reimbursements for 72,326 multiply-comorbid patients aged 66 and older with cLBP episodes and 1 of 4 treatment exposures: chiropractic manipulative treatment (CMT) alone, CMT followed or preceded by conventional medical care, or conventional medical care alone. We used propensity score weighting to address selection bias. Results After propensity score weighting, total and per-episode day Part A, Part B, and Part D Medicare reimbursements during the cLBP treatment episode were lowest for patients who used CMT alone; these patients had higher rates of healthcare use for low back pain but lower rates of back surgery in the year following the treatment episode. Expenditures were greatest for patients receiving medical care alone; order was irrelevant when both CMT and medical treatment were provided. Patients who used only CMT had the lowest annual growth rates in almost all Medicare expenditure categories. While patients who used only CMT had the lowest Part A and Part B expenditures per episode day, we found no indication of lower psychiatric or pain medication expenditures associated with CMT. Conclusions This study found that older multiply-comorbid patients who used only CMT during their cLBP episodes had lower overall costs of care, shorter episodes, and lower cost of care per episode day than patients in the other treatment groups. Further, costs of care for the episode and per episode day were lower for patients who used a combination of CMT and conventional medical care than for patients who did not use any CMT. These findings support initial CMT use in the treatment of, and possibly broader chiropractic management of

  20. Burnout among chiropractic practitioners: real or imagined an exploratory study protocol

    PubMed Central

    2012-01-01

    Burnout is a psychological syndrome of emotional exhaustion, depersonalization and reduced personal accomplishment that has been found to exist in a significant number of healthcare and helping professionals. It imposes a significant societal burden by shortened practitioner lifespan, decreased efficiency, negative health outcomes and poorer levels of patient care. Theoretical models suggest that it appears to be the result of a complex interaction between job resources and job demands. It may be reasonable to conclude that Chiropractic professionals experience similar vocational demands and thus experience significant levels of occupational stress and subsequent burnout. However the data on burnout within the chiropractic profession is limited. It is possible that this results in significant negative outcomes on chiropractors and their patients. Therefore, the objective of this paper is to demonstrate the need to explore burnout in chiropractic practice and offer a research protocol for a potential study. PMID:22369737

    2016-01-01

    Introduction: Patient-reported outcome measures are frequently used to monitor patient progress during chiropractic care, yet student interns utilizing such assessments are unfamiliar with what magnitude of change (MCID) is considered beneficial to the patient. Objective: This work seeks to determine chiropractic intern knowledge of MCID. Methods: A five-item survey was administered to 104 chiropractic student interns. Results: Nearly one-third of the interns correctly defined the MCID acronym, and approximately one-third of the interns knew at least one MCID value for the outcome assessments in the EHR. Surprisingly, 20% of the interns reported knowledge of at least one MCID value, but answered incorrectly pertaining to the MCID acronym. Conclusion: Student interns value patient perception, but have limited knowledge of MCID values. Addressing this gap will improve their understanding of patient progress and inform their treatment decisions both in the outpatient clinic and in their practices following graduation. PMID:27713580

    Aims To assess whether primary sector healthcare in the form of chiropractic care is cost-effective compared with self-management in patients with musculoskeletal chest pain, that is, a subgroup of patients with non-specific chest pain. Methods and results 115 adults aged 18–75 years with acute, non-specific chest pain of musculoskeletal origin were recruited from a cardiology department in Denmark. After ruling out acute coronary syndrome and receiving usual care, patients with musculoskeletal chest pain were randomised to 4 weeks of community-based chiropractic care (n=59) or to a single information session aimed at encouraging self-management as complementary to usual care (n=56). Data on resource use were obtained from Danish national registries and valued from a societal perspective. Patient cost and health-related quality-adjusted life years (QALYs; based on EuroQol five-dimension questionnaire (EQ-5D) and Short Form 36-item Health Survey (SF-36)) were compared in cost-effectiveness analyses over 12 months from baseline. Mean costs were €2183 lower for the group with chiropractic care, but not statistically significant (95% CI −4410.5 to 43.0). The incremental cost-effectiveness ratio suggested that chiropractic care was cost-effective with a probability of 97%, given a threshold value of €30 000 per QALY gained. In both groups, there was an increase in the health-related quality of life, and the mean increases were similar over the 12-month evaluation period. The mean differences in QALYs between the groups were negligible. Conclusions Chiropractic care was more cost-effective than self-management. Therefore, chiropractic care can be seen as a good example of a targeted primary care approach for a subgroup of patients with non-specific chest pain. Trial registration number NCT00462241.

    Objective The purpose of this case study is to present chiropractic management of a patient with chronic low back pain by focusing on the craniomandibular system. Clinical Features A 37-year-old man consulted a chiropractor for pain in the lumbosacral area with radiation down the anterolateral side of the upper left leg. The symptoms started after a fall the previous year. Examination showed a post-traumatic chronic L4-L5 facet dysfunction and left sacro-iliac joint dysfunction. Chiropractic spinal manipulation to the lumbar spine and pelvis gave only temporary relief from the pain. Intervention and Outcome A year later a bone scintigraphy was conducted, in which a lesion was found over the right sphenoid area. Cranial treatment of this area was added to the chiropractic treatment plan. After this treatment, the patient reported that he was pain free and could return to normal activities of daily living. Conclusion The clinical progress of this case suggests that for some patients, adding craniosacral therapy may be helpful in patients with low back symptoms. PMID:26644786

  4. Symptomatic reactions, clinical outcomes and patient satisfaction associated with upper cervical chiropractic care: A prospective, multicenter, cohort study

    PubMed Central

    2011-01-01

    Background Observational studies have previously shown that adverse events following manipulation to the neck and/or back are relatively common, although these reactions tend to be mild in intensity and self-limiting. However, no prospective study has examined the incidence of adverse reactions following spinal adjustments using upper cervical techniques, and the impact of this care on clinical outcomes. Methods Consecutive new patients from the offices of 83 chiropractors were recruited for this practice-based study. Clinical outcome measures included 1) Neck pain disability index (100-point scale), 2) Oswestry back pain index (100-point scale), 3) 11-point numerical rating scale (NRS) for neck, headache, midback, and low back pain, 4) treatment satisfaction, and 5) Symptomatic Reactions (SR). Data were collected at baseline, and after approximately 2 weeks of care. A patient reaching sub-clinical status for pain and disability was defined as a follow-up score <3 NRS and <10%, respectively. A SR is defined as a new complaint not present at baseline or a worsening of the presenting complaint by >30% based on an 11-point numeric rating scale occurring <24 hours after any upper cervical procedure. Results A total of 1,090 patients completed the study having 4,920 (4.5 per patient) office visits requiring 2,653 (2.4 per patient) upper cervical adjustments over 17 days. Three hundred thirty- eight (31.0%) patients had SRs meeting the accepted definition. Intense SR (NRS ≥8) occurred in 56 patients (5.1%). Outcome assessments were significantly improved for neck pain and disability, headache, mid-back pain, as well as lower back pain and disability (p <0.001) following care with a high level (mean = 9.1/10) of patient satisfaction. The 83 chiropractors administered >5 million career upper cervical adjustments without a reported incidence of serious adverse event. Conclusions Upper cervical chiropractic care may have a fairly common occurrence of mild intensity SRs

    Introduction The purpose of this study was to characterize the type, nature and frequency of injuries sustained by chiropractic students during their undergraduate training. Methods Chiropractic students in their second, third and fourth year of study at a chiropractic college were asked to complete a questionnaire that chronicled and described the occurrence of any side effects they may have sustained at the hands of their peers during technique class. Students were also asked to record their anthropomorphic characteristic. Results Of 450 questionnaires distributed, 292 were completed and returned to the authors. Of the 292 respondents, 127 reported to have experienced an injury, although the total number of injuries was 161. The most common site of injury was the lumbopelvic region. Students reported that it was during their second year of study that they experienced the highest number of injuries. Symptoms occurred the same day as the event in 85% of cases. The most common characteristic of symptoms reported was pain, followed by local stiffness, headache, dizziness, fatigue, diffuse stiffness and cramps. Two thirds of students described the extent of their injuries from ‘light’ to ‘a fair bit’. Three quarters of injuries resolved within the first 72 hours of the event. No treatment was sought by 89 (55%) of the respondents. More than half of students reported that their activities of daily living were either ‘not’ or ‘somewhat’ affected. There were three reports of long-term complaints. No statistically significant differences were found between the group of students reporting to be injured compared to those students not injured with respect to their age, gender, weight or height. Conclusion Chiropractic students experience side effects during their undergraduate training that are very similar to those experienced by patients under clinical care. PMID:17549151

    Objectives The purpose of this study was to retrospectively report the results of patients who completed an exercise-based chiropractic program and its potential to alter the natural progression of adult scoliosis at 24 months after the clinic portion of treatment was concluded. Methods A retrospective chart review was conducted at 2 spine clinics in Michigan, USA. Each clinic uses the same chiropractic rehabilitation program to treat patients with adult scoliosis. Multidimensional patient outcomes included radiographic, respiratory, disability, and pain parameters. Outcomes were measured at baseline, at end of active treatment, and at long-term follow-up. Results A total of 28 patients fit the inclusion criteria for the study. The average beginning primary Cobb angle was 44° ± 6°. Patients received the same chiropractic rehabilitation program for approximately 6 months. At the end of active treatment, improvements were recorded in Cobb angle, pain scores, spirometry, and disability rating. All radiographic findings were maintained at 24-month follow-up. Conclusion This report is among the first to demonstrate sustained radiographic, self-rated, and physiologic benefits after treatment ceased. After completion of a multimodal chiropractic rehabilitation treatment, a retrospective cohort of 28 adult scoliosis patients reported improvements in pain, Cobb angle, and disability immediately following the conclusion of treatment and 24 months later.

    Objective The purpose of this case series is to report on symptomatic and quality of life (QoL) changes in 7 older adult chiropractic patients who were receiving care using Activator Methods Chiropractic Technique (AMCT). Clinical Features Seven patients were selected from 2 chiropractic offices in Auckland, New Zealand. Patients were included if they were older adults receiving AMCT care and for whom at least 2 QoL assessments had been performed. The patients, aged 69-80 years, primarily received care for a variety of musculoskeletal complaints. Intervention and Outcomes The patients reported improvements in their presenting complaints as well as a number of nonmusculoskeletal symptoms. Each patient demonstrated clinical improvements in their RAND 36-Item Short Form Health Survey (SF-36) results. The average improvement in QoL measured using a SF-36 questionnaire was 8.0 points in the physical component and 4.1 points in the mental component. Four cases had a second progress evaluation using the SF-36 and showed an overall improvement of 5.2 in the physical and 9.8 in the mental components from baseline. Conclusion This case series describes an improvement in QoL, as measured by the SF-36 instrument, as well as subjectively reported improvements in both musculoskeletal and nonmusculoskeletal symptoms in 7 older adults receiving chiropractic care.

    John J. Nugent, D.C. is remembered by many as either the “Abraham Flexner of Chiropractic” or the “anti-Christ of Chiropractic.” From 1941 until his forced retirement in 1959, the Irish-born Palmer graduate was one of the most important factors in the profession's educational reforms. Yet Nugent's work as the National Chiropractic Association's (NCA's) director of research was not the beginning of the campaign to upgrade chiropractic education. This paper looks at earlier influences and events which set the stage for Nugent's campaign. Among these were the introduction of licensure for chiropractors, the self-defeating actions of B.J. Palmer, the introduction of basic science legislation, the lethargy of the schools, and the struggle for control of education between the schools, on the one hand, and the NCA and the Council of State Chiropractic Examining Boards on the other ImagesFigure 1Figure 3Figure 4Figure 5Figure 6Figure 7Figure 9Figure 10Figure 11Figure 12Figure 13Figure 14Figure 15Figure 16Figure 17Figure 18Figure 19Figure 20Figure 21Figure 22Figure 23Figure 24Figure 25Figure 26Figure 28Figure 29Figure 30Figure 31Figure 32Figure 33Figure 34Figure 35Figure 36Figure 37Figure 38

    2014-01-01

    Background Low back pain in pregnancy is common and research evidence on the response to chiropractic treatment is limited. The purposes of this study are 1) to report outcomes in pregnant patients receiving chiropractic treatment; 2) to compare outcomes from subgroups; 3) to assess predictors of outcome. Methods Pregnant patients with low back or pelvic pain, no contraindications to manipulative therapy and no manual therapy in the prior 3 months were recruited. Baseline numerical rating scale (NRS) and Oswestry questionnaire data were collected. Duration of complaint, number of previous LBP episodes, LBP during a previous pregnancy, and category of pain location were recorded. The patient’s global impression of change (PGIC) (primary outcome), NRS, and Oswestry data (secondary outcomes) were collected at 1 week, 1 and 3 months after the first treatment. At 6 months and 1 year the PGIC and NRS scores were collected. PGIC responses of ‘better’ or ‘much better’ were categorized as ‘improved’. The proportion of patients ‘improved’ at each time point was calculated. Chi-squared test compared subgroups with ‘improvement’. Baseline and follow-up NRS and Oswestry scores were compared using the paired t-test. The unpaired t-test compared NRS and Oswestry scores in patients with and without a history of LBP and with and without LBP during a previous pregnancy. Anova compared baseline and follow-up NRS and Oswestry scores by pain location category and category of number of previous LBP episodes. Logistic regression analysis also was also performed. Results 52% of 115 recruited patients ‘improved’ at 1 week, 70% at 1 month, 85% at 3 months, 90% at 6 months and 88% at 1 year. There were significant reductions in NRS and Oswestry scores (p < 0.0005). Category of previous LBP episodes number at one year (p = 0.02) was related to ,improvement’ when analyzed alone, but was not strongly predictive in logistic regression. Patients with

    Objective The purpose of this study was to describe the demographics, presenting complaints, and health history of new patients seeking treatment at a free chiropractic clinic within a university health center. Methods A retrospective analysis of patient files from 2008 to 2009 was performed for a free student chiropractic clinic in the Buffalo, NY, area. Demographics, presenting complaints, and health history of new patients seeking treatment were recorded. Results There were 343 new chiropractic patient files. Most patients were between the ages of 18 and 30 years (n = 304, 88%) with an almost equal distribution of men (n = 163, 48%) and women (n = 180, 52%). The patients were mostly single (n = 300, 87%). Patients self-reported that their case histories excluded a current medical diagnosis (n = 261, 76%), previous history of disease (n = 216, 63%), allergies (n = 240, 70%), previous surgical procedures (n = 279, 81%), and medication use (n = 250, 73%). The frequencies of spinal complaints were as follows: lumbar spine, n = 176 (51%); cervical spine, n = 78 (23%); and thoracic spine, n = 44 (13%). Maintenance care, headaches, and spine-related upper and lower extremities complaints accounted for the other 13% of patients treated. Half were chronic (n = 172, 50%), and a third were acute (n=108, 31%). Patients averaged 6 chiropractic visits, with 88% having 11 visits or less. Conclusion This study found that new patients seeking care at a free student chiropractic clinic within a university health center in the Buffalo area mainly consisted of young single adults, with chronic lumbar spine complaints with few comorbidities.

    Background Context Low back pain (LBP) is one of the leading causes of disability worldwide and among the most common reasons for seeking primary sector care. Chiropractors, physical therapists and general practitioners are among those providers that treat LBP patients, but there is only limited evidence regarding the effectiveness and economic evaluation of care offered by these provider groups. Purpose To estimate the clinical effectiveness and to systematically review the literature of full economic evaluation of chiropractic care compared to other commonly used care approaches among adult patients with non-specific LBP. Study Design Systematic reviews of interventions and economic evaluations. Methods A comprehensive search strategy was conducted to identify 1) pragmatic randomized controlled trials (RCTs) and/or 2) full economic evaluations of chiropractic care for low back pain compared to standard care delivered by other healthcare providers. Studies published between 1990 and 4th June 2015 were considered. Primary outcomes included pain, functional status and global improvement. Study selection, critical quality appraisal and data extraction were conducted by two independent reviewers. Data from RCTs with low risk of bias were included in a meta-analysis to determine effect estimates. Cost estimates of full economic evaluations were converted to 2015 USD and results summarized using Slavin’s qualitative best-evidence synthesis. Results Six RCTs and three full economic evaluations were scientifically admissible. Five RCTs with low risk of bias compared chiropractic care to exercise therapy (n = 1), physical therapy (n = 3) and medical care (n = 1). Overall, we found similar effects for chiropractic care and the other types of care and no reports of serious adverse events. Three low to high quality full economic evaluations studies (one cost-effectiveness, one cost-minimization and one cost-benefit) compared chiropractic to medical care. Given the divergent

    2015-01-01

    Objective The aim of this study was to conduct an international survey of the perceived optimal level of anatomy teaching from anatomy academics and practicing chiropractors. We hypothesized that the optimum level of anatomical understanding for chiropractic students does not differ between the anatomists teaching the students and practicing chiropractors. Methods The opinion of anatomists teaching in a chiropractic course (n = 16) was compared to practicing chiropractors (n = 589). The students' level of understanding was based on the revised Bloom's taxonomy for 16 different curriculum areas. Anatomists were recruited by contacting the accredited chiropractic courses worldwide. Snowball sampling was used for the practicing chiropractors. Independent-samples Mann-Whitney U tests were used to compare the results of anatomists and chiropractors. Results Opinions differed between anatomists and chiropractors on 9 out of the 16 questions. Where opinions differed, chiropractors recommended a higher standard of anatomical knowledge. The level suggested by chiropractors for these curriculum areas is equal to the “evaluating” level where chiropractic students can remember, understand, apply, and analyze anatomical knowledge to be able to justify a clinical decision. Conclusion Compared to anatomists working in chiropractic programs, chiropractors suggest a higher standard of anatomy be taught to undergraduates. Collaboration between chiropractors and anatomists would likely be beneficial in creating or modifying anatomy curricula for chiropractic students. PMID:25517738

    Objective The purpose of this commentary is to describe the conflicts in the history of chiropractic’s professionalization and conflict through the path of increasing educational standards and accreditation using the lens of developmental structuralism. Discussion Within the story of chiropractic’s professionalization and accreditation lie the battles between competing worldviews. Gibbons proposed 4 periods of chiropractic’s educational history; this article proposes a fifth period along with a new methodological approach to explore the complexity of chiropractic’s history. The methodology draws upon constructive developmental psychology and proposes 5 levels of thinking common to the individuals from chiropractic’s history. By using a psychological framework to analyze historical events, it appears that the battle within chiropractic education continues at present. Several important issues are explored: the Council on Chiropractic Education's origins in the medical paradigm and rational thinking, the pre-rational, rational, and post-rational critics of the Council on Chiropractic Education, the schools of thought that were reified or emerged from the history, as well as the more recent legal, economic, and social pressures, which helped to shape chiropractic's accreditation and professionalization. Conclusion A transrational approach, one that includes the partial truths of all perspectives, is a first step to allow for a richer understanding of how the interior worldviews, individual actions, and the exterior forces (legal, economic, political, and educational) brought forth the chiropractic clashes together. Viewing the conflicts within chiropractic from this approach may foster new educational structures to evolve. PMID:25431541

    Background Chiropractic’s success as a health care profession is evidenced in part by the rising number of practitioners. Paradoxically, this success may start to cost the profession, as the number of consumers may not be increasing proportionally. Fewer patients mean less income for practitioners. Some chiropractors are responding to these pressures by marketing health products, and services Objectives To describe the extent to which Alberta chiropractors with websites sold health products and the extent to which fee discounts/service inducements were advertised. To consider these practices in the context of chiropractic codes of conduct and ethics. Methods Chiropractic websites in the province of Alberta were identified using the online Telus Business Finder and cross-referenced with the Yellow Pages print directories. The websites were searched and an inventory of the health products for sale was recorded. Fee discounts and service inducements were also recorded. Results 56 websites were identified and reviewed. Just under two-thirds of the chiropractic websites surveyed contained information on health products for sale. Orthotics were sold most often (N = 29 practices; 51.8%), followed by pillows and supports (N = 15: 26.8%), vitamins/nutritional supplements (N = 15; 26.8%) and exercise/rehabilitation products (N = 10; 17.9%). Nine practices (16.1%) offered some type of inducement to potential customers. These included discounts on treatment packages (N = 2; 3.6%), free gait/ posture analyses (N = 2; 3.6%) and free general consultations with the chiropractors (N = 3; 5.4%) Conclusions The marketing of health care products and services by chiropractors in Alberta is common. Such practices raise ethical considerations for the profession. Professional guidelines vary on the acceptability of these practices. Consumer and practitioner perspectives and practices regarding retailing need to be further examined. PMID:17657302

    Background Manipulation is a common treatment for non-specific neck pain. Neck manipulation, unlike gentler forms of manual therapy such as mobilisation, is associated with a small risk of serious neurovascular injury and can result in stroke or death. It is thought however, that neck manipulation provides better results than mobilisation where clinically indicated. There is long standing and vigorous debate both within and between the professions that use neck manipulation as well as the wider scientific community as to whether neck manipulation potentially does more harm than good. The primary aim of this study is to determine whether neck manipulation provides more rapid resolution of an episode of neck pain than mobilisation. Methods/Design 182 participants with acute and sub-acute neck pain will be recruited from physiotherapy, chiropractic and osteopathy practices in Sydney, Australia. Participants will be randomly allocated to treatment with either manipulation or mobilisation. Randomisation will occur after the treating practitioner decides that manipulation is an appropriate treatment for the individual participant. Both groups will receive at least 4 treatments over 2 weeks. The primary outcome is number of days taken to recover from the episode of neck pain. Cox regression will be used to compare survival curves for time to recovery for the manipulation and mobilisation treatment groups. Discussion This paper presents the rationale and design of a randomised controlled trial to compare the effectiveness of neck manipulation and neck mobilisation for acute and subacute neck pain.

    Objective This review details the anatomy and interactions of the postural and somatosensory reflexes. We attempt to identify the important role the nervous system plays in maintaining reflex control of the spine and posture. We also review, illustrate, and discuss how the human vertebral column develops, functions, and adapts to Earth's gravity in an upright position. We identify functional characteristics of the postural reflexes by reporting previous observations of subjects during periods of microgravity or weightlessness. Background Historically, chiropractic has centered around the concept that the nervous system controls and regulates all other bodily systems; and that disruption to normal nervous system function can contribute to a wide variety of common ailments. Surprisingly, the chiropractic literature has paid relatively little attention to the importance of neurological regulation of static upright human posture. With so much information available on how posture may affect health and function, we felt it important to review the neuroanatomical structures and pathways responsible for maintaining the spine and posture. Maintenance of static upright posture is regulated by the nervous system through the various postural reflexes. Hence, from a chiropractic standpoint, it is clinically beneficial to understand how the individual postural reflexes work, as it may explain some of the clinical presentations seen in chiropractic practice. Method We performed a manual search for available relevant textbooks, and a computer search of the MEDLINE, MANTIS, and Index to Chiropractic Literature databases from 1970 to present, using the following key words and phrases: "posture," "ocular," "vestibular," "cervical facet joint," "afferent," "vestibulocollic," "cervicocollic," "postural reflexes," "spaceflight," "microgravity," "weightlessness," "gravity," "posture," and "postural." Studies were selected if they specifically tested any or all of the postural reflexes

    Objective The purpose of this report is to describe 2 patients with coronary artery disease presenting with musculoskeletal symptoms to a chiropractic clinic. Clinical Features A 48-year-old male new patient had thoracic spine pain aggravated by physical exertion. A 61-year-old man under routine care for low back pain experienced a secondary complaint of acute chest pain during a reevaluation. Intervention and Outcome In both cases, the patients were strongly encouraged to consult their medical physician and were subsequently diagnosed with coronary artery disease. Following their diagnoses, each patient underwent surgical angioplasty procedures with stenting. Conclusion Patients may present for chiropractic care with what appears to be musculoskeletal chest pain when the pain may be generating from coronary artery disease necessitating medical and possibly emergency care.

    Statutory and administrative rules continue to influence curriculum in chiropractic colleges. Pressure is frequently exerted by jurisdictions to add classes or hours, or conversely to delete subject matter and procedures not included in the scope of practice acts. Lack of government funding and university affiliation perpetuates the diversity of curriculum content which must satisfy licensing boards driven by the varied scope of practice of statutes rather than following research supported standards of care.

    2013-01-01

    Objective The purpose of this study was to evaluate the feasibility of engaging in a series of larger studies measuring the effect of sacroiliac joint manipulation on walking kinematics using motion analysis technology. Methods Twelve college students engaged in a baseline 90-second gait analysis at 1.5 mph using infrared VICON cameras. Following this, they underwent a prone heel comparison test for functional leg length inequality. Upon examination, participants were then classified as follows: left short leg, right short leg, or no short leg. Participants in each of the 2 short leg branches of this study were then randomized to receive either chiropractic manipulative therapy to the posterior superior iliac spine on the short limb side or no manipulation. Recruitment was ongoing for this pilot study until 1 participant was recruited in each of the following 5 comparative study groups: left short leg—manipulation, left short leg—no manipulation (control 1), right short leg—manipulation, right short leg—no manipulation (control 2), and no short leg (control 3). All participants then underwent another 90-second gait analysis. Data were then grouped and submitted to a blinded biomechanist to determine if there were any unique biomechanical differences between the groups. Results No statistically significant differences were measured because of this being a pilot study with a small sample size. Conclusions The data from this study indicate that a series of larger studies with this design is feasible. PMID:24396314

    Objective : This study investigated the effect of completion of course prerequisites, undergraduate grade point average (GPA), undergraduate degree, and study habits on the performance of students in the biochemistry course at Palmer College of Chiropractic Florida. Methods : Students self-reported information regarding academic preparation at the beginning of the semester using a questionnaire. Final exam grade and final course grade were noted and used as measures of performance. Multivariate analysis of variance was used to determine if number of prerequisites completed, undergraduate GPA, undergraduate degree, hours spent studying in undergraduate study, and hours spent studying in the first quarter of the chiropractic program were associated significantly with the biochemistry final exam grade or the final grade for the biochemistry course. Results : The number of prerequisites completed, undergraduate degree, hours spent studying in undergraduate study, and hours spent studying in the first quarter of the chiropractic program did not significantly affect the biochemistry final exam grade or the final grade for the biochemistry course, but undergraduate GPA did. Subsequent univariate analysis and Tukey's post hoc comparisons revealed that students with an undergraduate GPA in the 3.5 to 3.99 range earned significantly higher final course grades than students with an undergraduate GPA in the 2.5 to 2.99 range. Conclusion : No single variable was determined to be a factor that determines student success in biochemistry. The interrelationship between the factors examined warrants further investigation to understand fully how to predict the success of a student in the biochemistry course.

  11. Current efforts in chiropractic quality assurance and standards of care †

    PubMed Central

    Hansen, Daniel T

    1991-01-01

    The chiropractic profession has recently begun to proactively address the problems identified by the health care industry. Prompted by rising health care costs, careful analysis revealed that the major culprit was the variance in the delivery of health care. Concerned with outside regulation, health professionals, both in the USA and Canada, are generating clinical guidelines that will serve as templates for the development of standards of care. More specifically, the chiropractic profession is identifying and establishing standards of practice. This in part is due to published data illustrating the variations in treatment frequencies between geographic locations. Acknowledging these variations will enable the identification of solutions. The solutions will be formulated from a growing knowledge base comprised of printed literature and the opinions of recognized experts through consensus panels. The result is the creation of practice standards and guidelines that will serve to answer concerns of accountability and ultimately to protect the public. The process from the creation to the implementation of the guidelines is necessarily detailed; but can be enhanced by the use of clinical algorithms. Clinical algorithms describe a step wise procedure to patient management that may impact upon patient care, health care costs and outcome measures. As chiropractic achieves greater visibility, it will be expected to perform at the same level of accountability as the other health provider groups. Each chiropractor should understand the process and its limitations, and be prepared to contribute in the development, distribution and implementation of reasonable practice guidelines.

    Objective High levels of stress and fatigue are associated with decreased academic success, well-being, and quality of life. The objective of this research was to quantify levels of perceived stress and fatigue among chiropractic students to identify sources of and student coping mechanisms for perceived stress and fatigue and to identify the relationship between students' perceived stress and fatigue. Methods A survey comprised of the Perceived Stress Scale, the Undergraduate Sources of Stress Survey, and the Piper Fatigue Scale was administered to chiropractic students in their 2nd, 5th, and 8th trimesters of doctoral study. Data were analyzed by descriptive statistics, 1-way analysis of variance, and linear correlation tests. Results Students reported having moderate to high levels of stress and fatigue, with higher levels of stress and fatigue seen in women than in men. A nonsignificant difference among stress scores and a significant difference among fatigue scores were observed based on program term. Levels of stress predicted levels of fatigue, and stress was strongly correlated with psychological health, relationships with family members, mood, and need for learning accommodations. Fatigue was strongly correlated with psychological health, academic demands, and conflicts between studies and other activities. Conclusion There are differences in the reporting of perceived stress and fatigue levels in this chiropractic student population based on gender. The correlation between fatigue and stress also suggests that measures that may alleviate one may likely affect the other. PMID:27552030

    2015-01-01

    Increasing the diversity of practitioner and patient populations has been identified as a worthy goal in the chiropractic profession, which has predominantly white male practitioners and white female patients in the USA. Toward that end, 'diversity' has been the topic of several papers and was the theme of a 2012 conference of chiropractic educators. However, generally just the microcosm of the interactions of practitioners with patients or teachers with students has been discussed. The macrocosm of larger societal issues and government policies has not been broached. Examples of issues and policies that affect diversity within a profession include portrayals of, and value judgements on diversity by the media and politicians, as well as public funding for healthcare and education. Diversity was defined in this paper to mean differences in race, sex, sexual orientation, economic status, ethnicity, religion and other life circumstances in a population. The purpose of this paper is to raise awareness of evidence that social issues and government policy affect the diversity of practitioners and patients, and to suggest that the barriers to diversity present in these realms be addressed with a cogent, profession-wide effort in order to help increase the diversity of people involved with chiropractic.

    Objective The purpose of this study is to describe the knowledge base and clinical practices regarding concussion by sports-certified doctors of chiropractic. Methods A 21-item survey was distributed to the 312 attendees of the 2014 American Chiropractic Board of Sports Physicians Sports Sciences Symposium. Results were measured by frequency analysis and descriptive statistics for all surveys completed by sports-certified chiropractors. Results Seventy-six surveys were returned by sports-certified doctors of chiropractic. All (N = 76) 100% of respondents believe that the evaluation of concussion should be performed by a health care provider with training in concussion. The respondents actively assess and manage concussion in adults (96%), adolescents (95%), and children (75%). A majority (79%) of respondents believe that the Sideline Concussion Assessment Tool–3 represents a current standard of care for the sideline evaluation of the athlete who possibly has sustained a sport concussion. Most respondents agreed or strongly agreed that manual therapies may be appropriate in certain circumstances in adults (80%) and minors (80%). Conclusion This cross section of certified sports chiropractors strongly believes that the evaluation of concussion should be performed by a health care provider with specific training in concussion. A high percentage of the sports-certified chiropractors who responded assess and manage sport concussion in their practice, and many of them endorse the use of the Sideline Concussion Assessment Tool–3 as a sideline assessment tool.

    Objective The purpose of this report is to describe the chiropractic management of a case of lateral epicondylitis with active release techniques (ART). Clinical features A 48-year-old white man presented to a chiropractic clinic with a complaint of left lateral elbow pain that began 2 years previous with insidious onset. The patient reported an inability to play 18 consecutive holes of golf due to the pain. Intervention and outcome Treatment consisted of 5 sessions of ART (a soft tissue technique that is applied to muscles, fascia, tendons, ligaments, and nerves) applied to the left elbow soft tissue over a duration of 3 weeks. The patient reported an absence of pain and ability to consistently play 18 consecutive holes of golf up to 3 times per week at 4 and 8 weeks post-treatment. Conclusion This patient with lateral epicondylitis responded favorably to chiropractic treatment using the application of ART, as demonstrated by reduced pain and increased functional outcomes.

The intent of this project is to better understand the Canadian Memorial Chiropractic College (CMCC) students’ perceptions and practices of PA and exercise prescription as this may predict exercise counselling they will provide to future patients. Methods: A 27-item survey was distributed to Canadian Memorial Chiropractic College (CMCC) students (N = 744). The survey determined the proportion of CMCC students that meet the (2012) Canadian Physical Activity Guidelines. Additionally the survey recorded students’ perceptions of PA counselling during patient visits and their own example of maintaining a healthy lifestyle. Results: The response rate for the survey was 46% (N = 343). By using average estimates, it was determined that 72% of the respondents meet the (2012) Canadian Physical Activity Guidelines. 86% of the respondents perceived PA counselling to be usually or always relevant during patient interactions, and approximately 73% believed that exercise counselling is highly relevant to chiropractic practice. Furthermore, at least 88% percent believed that chiropractors must adhere to a healthy lifestyle in order to effectively model a healthy lifestyle to their patients. Conclusions: A high proportion of CMCC students meet PA guidelines, and perceive PA counselling to be highly relevant and important to patient encounters. PMID:28065988

    Purpose: Problem-based learning (PBL) is usually conducted in small-group learning sessions with approximately eight students per facilitator. In this study, we implemented a modified version of PBL involving collaborative groups in an undergraduate chiropractic program and assessed its pedagogical effectiveness. Methods: This study was conducted at the International Medical University, Kuala Lumpur, Malaysia, and involved the 2012 chiropractic student cohort. Six PBL cases were provided to chiropractic students, consisting of three PBL cases for which learning resources were provided and another three PBL cases for which learning resources were not provided. Group discussions were not continuously supervised, since only one facilitator was present. The students’ perceptions of PBL in collaborative groups were assessed with a questionnaire that was divided into three domains: motivation, cognitive skills, and perceived pressure to work. Results: Thirty of the 31 students (97%) participated in the study. PBL in collaborative groups was significantly associated with positive responses regarding students’ motivation, cognitive skills, and perceived pressure to work (P<0.05). The students felt that PBL with learning resources increased motivation and cognitive skills (P<0.001). Conclusion: The new PBL implementation described in this study does not require additional instructors or any additional funding. When implemented in a classroom setting, it has pedagogical benefits equivalent to those of small-group sessions. Our findings also suggest that students rely significantly on available learning resources. PMID:25961676

    Access to the clinical laboratory by chiropractors is an important issue in the context of the role of the chiropractor as a primary health care provider and the public’s right to optimal health care in the most efficient and cost-effective manner possible. In its efforts to gain the right to do so in Canada, the profession will have to identify and be able to justify the use of tests that would enhance the ability of its constituents to participate in the delivery of health care more effectively. In this article we have presented a set of tests which was originally developed as part of a presentation on laboratory services restructuring to the Ontario Ministry of Health by a joint committee of the College of Chiropractors of Ontario, the Ontario Chiropractic Association, and the Canadian Memorial Chiropractic College in 1996. A rationale for the use of each test in the context of chiropractic practice is presented. It is argued that the list of tests could be more, or less extensive than presented, but that it is necessary for the profession to engage in constructive debate and identify its needs more precisely in the interest of more effectively fulfilling its mandate as a primary health care profession.

    Objective The purpose of this study was to examine predictors for success on Parts I and II of the National Board of Chiropractic Examiners (NBCE) written examinations. Methods Two validity studies were conducted to examine the criterion validity of Logan College assessments for Part I and II NBCE scores. Both studies consisted of a longitudinal design to examine the validity of entrance grade point average (GPA), in-program chiropractic course content GPA, and an institutional practice exam on Parts I and II of the NBCE. Results Analyses revealed that Part I GPA and practice exam scores combined accounted for 72% of the variance within Part I NBCE scores. Furthermore, every subtest of the Part I NBCE could be reliably predicted by course performance. In the 2nd study, Part I GPA, Part I NBCE score, and Part II GPA accounted for 75% of the variance within Part II NBCE scores. Conclusions Internal training and educational assessments (eg, course grades and practice exams) proved to be strong determinants of NBCE performance above and beyond initial levels of preparedness, thus validating the impact of the chiropractic curriculum on NBCE test achievement.

    The first few chiropractors in Massachusetts practiced as they desired, unmolested by the authorities. All this changed after Joe Shelby Riley, D.C., established his New England College of Chiropractic in Boston in 1911. Printed publicity got out as to the tuition costs, length of the course and what graduates could expect to earn in a short time, when the police stepped in. They arrested first J.O. Zimmerman, D.C., of Boston, followed by Dr. Riley, a school president, then Samuel Mendelson, D.C., in Lynn, all for illegal practices. From the judical decision in Commonwealth v Zimmerman, 1915 by the Supreme Judicial Court (State Supreme Court), the high court held that the practice of chiropractic to be the illegal practice of medicine without a license, according to the Commonwealth laws of 1902. Next came the Commonwealth v New England College of Chiropractic; this case was shortly followed on appeal from the Municipal Court in Boston, to the Suffolk County Superior Court, to the Supreme Judicial Court like Zimmerman. In this case against Dr. Riley and his school, the high court affirmed the school to be illegal because Dr. Riley had failed to receive authority from the Great General Court (the Legislature) to get a bill passed authorizing the school to have the right of granting degrees. According to the Boston Herald, all this legal action was the culmination of a campaign spearheaded by the Massachusetts Medical Society.

    This study used an observational design to examine the kinematics of spinal manipulative therapy (SMT) by determining the acceleration characteristics of the manipulative input at the cervical, thoracic, and lumbar spinal regions. Studies of SMT have been restricted to measuring the forces that result from the manipulative input. Several studies have indicated the rate of force development is a key parameter of clinically delivered SMT. Despite this, the movement strategies employed during SMT, including acceleration, have not been directly measured. Participants (n = 29) were recruited from a private practice chiropractic clinic. A wireless accelerometer attached to the clinician's hand was used to characterize the thrust phase of the SMT treatments. Significant differences were found across each spinal region for acceleration amplitude parameters (p < 0.0001). Post-hoc analysis indicated that amplitudes significantly increased in order from thoracic to cervical to lumbar regions (p < 0.0001). Spinal level was also a significant factor in determining the temporal parameters of hand acceleration during SMT (p < 0.0005). This study provides a description of the acceleration properties of clinically delivered SMT. Consistent with that reported for SMT forces, acceleration amplitudes varied significantly across spinal regions with relatively little differences in acceleration latencies. Notably, acceleration amplitudes and latencies were not associated with each other within spinal regions. These findings indicate that changes in acceleration amplitude, rather than latency, are used to tailor SMT to individuals.

    Objective The purpose of this study is to examine the self-report of experiences, attitudes, and perceived educational needs of American Chiropractic Association members regarding practice in integrated health care settings. Methods This was a descriptive observational study of the American Chiropractic Association members. Participants completed an electronic survey reporting their current participation and interest in chiropractic integrated practice. Results The survey was completed in 2011 by 1142 respondents, for a response rate of 11.8%. The majority of respondents (82.9%) did not currently practice in an integrated setting, whereas 17.1% did. Those practicing in various integrated medical settings reported delivering a range of diagnostic, therapeutic, and case management services. Participation in administrative and scholarly activities was less common. Respondents not practicing in integrated settings reported being interested in delivering a very similar array of clinical services. Doctors of chiropractic practicing in hospital or outpatient medical facilities reported frequent engagement in interprofessional collaboration. Both nonintegrated and integrated respondents reported very similar educational interests on a range of clinical topics. Conclusion The findings of this survey provide insight into the experiences, participation, and interests in integrated clinical practice for members of the American Chiropractic Association.

    Objective The purpose of this article is to present select concepts and theories of bureaucratic structures and functions so that chiropractic physicians and other health care professionals can use them in their respective practices. The society-culture-personality model can be applied as an organizational instrument for assisting chiropractors in the diagnosis and treatment of their patients irrespective of locality. Discussion Society-culture-personality and social meaningful interaction are examined in relationship to the structural and functional aspects of bureaucracy within the health care institution of a society. Implicit in the examination of the health care bureaucratic structures and functions of a society is the focus that chiropractic physicians and chiropractic students learn how to integrate, synthesize, and actualize values and virtues such as empathy, integrity, excellence, diversity, compassion, caring, and understanding with a deep commitment to self-reflection. Conclusion It is essential that future and current chiropractic physicians be aware of the structural and functional aspects of an organization so that chiropractic and other health care professionals are able to deliver care that involves the ingredients of quality, affordability, availability, accessibility, and continuity for their patients.

    Cancers of the breast, kidney, lungs, prostate and thyroid metastasize to the musculoskeletal system in the majority of patients with malignancy. This report chronicles the case of a 65-year-old female with a known history of breast cancer who presented to a chiropractic clinic. Once metastasis was ruled out as the cause of her complaint, the patient was treated with manual therapies and exercises. As the patient’s treatments progressed and her pain improved, she presented with a new complaint of ‘pressure’ in her head. Advanced imaging revealed metastasis to the brain and subsequently to the spine. The aim of this case is to heighten awareness of the presentation of metastasis to the brain and the spine in a chiropractic patient, and to demonstrate the benefit of chiropractic care in the management of such patients.

    2015-01-01

    Background: The burden of fees for chiropractic services rendered often falls on the patient and must be provided out-of-pocket regardless of their socioeconomic status and clinical need. Universal healthcare coverage reduces the financial barrier to healthcare utilization, thereby increasing the opportunity for the financially disadvantaged to have access to care. In 2011 the Canadian Province of Manitoba initiated a pilot program providing access to chiropractic care within the Mount Carmel Clinic (MCC), a non-secular, non-profit, inner city community health centre. Objective: To describe the initial integration of chiropractic services into a publically funded healthcare facility including patient demographics, referral patterns, treatment practices and clinical outcomes. Method: A retrospective database review of chiropractic consultations in 2011 (N=177) was performed. Results: The typical patient referred for chiropractic care was a non-working (86%), 47.3(SD=16.8) year old, who self-identified as Caucasian (52.2%), or Aboriginal (35.8%) and female (68.3%) with a body mass index considered obese at 30.4(SD=7.0). New patient consultations were primarily referrals from other health providers internal to the MCC (71.2%), frequently primary care physicians (76%). Baseline to discharge comparisons of numeric rating scale scores for the cervical, thoracic, lumbar, sacroiliac and extremity regions all exceeded the minimally clinically important difference for reduction in musculoskeletal pain. Improvements occurred over an average of 12.7 (SD=14.3) treatments, and pain reductions were also statistically significant at p<0.05. Conclusion: Chiropractic services are being utilized by patients, and referring providers. Clinical outcomes indicate that services rendered decrease musculoskeletal pain in an inner city population.

    This paper reviews my recent research in robotic manipulation and speculates on potentially fruitful directions for future work. My recent work is focused on nonprehensile manipulation: manipulating objects without grasping them. In particular, the paper surveys work on a single joint robot that orients parts on a conveyor belt; a robot that uses dynamics to snatch, roll, or throw objects; hitting things to position them; manipulating things whose shapes are not completely known; and integration of manipulation with locomotion. In the future, a broad view of robotics will allow us to focus on fundamental principles and at the same time address a variety of new applications.

    Purpose: The objective of this study was to determine to what extent the diagnostic and therapeutic procedures taught in the undergraduate program used for patients with lumbopelvic conditions are expected to be utilized by students during their clinical internship program at Canadian Memorial Chiropractic College or are being used by the clinical faculty. Methods: A confidential survey was distributed to clinical faculty at the college. It consisted of a list of diagnostic and therapeutic procedures used for lumbopelvic conditions taught at that college. Clinicians were asked to indicate the frequency with which they performed or they required students to perform each item. Results: Seventeen of 23 clinicians responded. The following procedures were most likely required to be performed by clinicians: posture; ranges of motion; lower limb sensory, motor, and reflex testing; and core orthopedic tests. The following were less likely to be required to be performed: Waddell testing, Schober's test, Gillet tests, and abdominal palpation. Students were expected to perform (or clinicians performed) most of the mobilization (in particular, iliocostal, iliotransverse, and iliofemoral) and spinal manipulative therapies (in particular, the procedures referred to as the lumbar roll, lumbar pull/hook, and upper sacroiliac) taught at the college. Conclusion: This study suggests that there was considerable, but not complete, vertical integration between the undergraduate and clinical education program at this college. PMID:20480014

    1986-12-01

    From a total pool of 1189 male and female patients with accident- (AC) and nonaccident- (NA) caused low back pain, 465 cases with completed therapy were studied for effectiveness of various chiropractic treatments. For those who completed therapy, the age distribution and incidence of this disorder were also studied. At the completion of the therapy, the response was evaluated as very good (pain-free, cured), better (very small degree of discomfort), relief (some reduction in pain) or no response to the treatment. The females with NA responded better than AC cases (p less than .001). However, male NA cases showed an increase in "no relief," but it was not significant (p = 0.052). The response of male AC cases was better than that of female AC cases (p less than 0.001). The cervical, thoracic, lumbar and ilium adjustment levels in female and male NA did not show any differences in response (p = 0.15, female; p = 0.46, male). The incidence of NA back pain disorders in both male and female was higher as compared to AC-caused back problems (p less than 0.001). The lower back pain problems did not show any age-specific association in either sex. Manipulative approaches in addition to nonmanipulative methods are superior to nonmanipulative measures alone, and females responded better to nonmanipulative care than did males.

    Objective This study investigated the effect of completion of course prerequisites, undergraduate grade point average (GPA), undergraduate degree, and study habits on the performance of students in the biochemistry course at Palmer College of Chiropractic Florida. Methods Students self-reported information regarding academic preparation at the beginning of the semester using a questionnaire. Final exam grade and final course grade were noted and used as measures of performance. Multivariate analysis of variance was used to determine if number of prerequisites completed, undergraduate GPA, undergraduate degree, hours spent studying in undergraduate study, and hours spent studying in the first quarter of the chiropractic program were associated significantly with the biochemistry final exam grade or the final grade for the biochemistry course. Results The number of prerequisites completed, undergraduate degree, hours spent studying in undergraduate study, and hours spent studying in the first quarter of the chiropractic program did not significantly affect the biochemistry final exam grade or the final grade for the biochemistry course, but undergraduate GPA did. Subsequent univariate analysis and Tukey's post hoc comparisons revealed that students with an undergraduate GPA in the 3.5 to 3.99 range earned significantly higher final course grades than students with an undergraduate GPA in the 2.5 to 2.99 range. Conclusion No single variable was determined to be a factor that determines student success in biochemistry. The interrelationship between the factors examined warrants further investigation to understand fully how to predict the success of a student in the biochemistry course. PMID:24295362

    2011-01-01

    Background Not much is known about the French chiropractic profession on, for example, level of consensus on clinical issues. Objectives The first objective was to investigate if French chiropractors' management choices appeared reasonable for various neck problem scenarios. The second objective was to investigate if there was agreement between chiropractors on the patient management. The third objective was to see to which degree and at what stages chiropractors would consider to interact with other health-care practitioners, such as physiotherapists, general practitioners and specialists. Method A questionnaire was sent to a randomly selected sample of all French chiropractors known to the national chiropractic college. It consisted of an invitation to participate in the study, a brief case description, and drawings of five stages of how a case of neck pain gradually evolves into a brachialgia to end up with a compromised spinal cord. Each stage offered five management choices. Participants were asked at what stages patients would be treated solely by the chiropractor and when patients would be referred out for second opinion or other care without chiropractic treatment, plus an open ended option, resulting in a "five-by-six" table. The percentages of respondents choosing the different management strategies were identified for the different scenarios and the 95% confidence intervals were calculated. There was a pre hoc agreement on when chiropractic care would or would not be suitable. Consensus was arbitrarily defined as "moderate" when 50- 69% of respondents agreed on the same management choice and as "excellent" when 70% or more provided the same answer. It was expected that inter professional contacts would be rare. Results The response rate was 53% out of 254 potential participants. The first two uncomplicated cases would generally have been treated by the chiropractors. As the patient worsened, the responses tended towards external assistance and for the

    Care for low back pain remains a clinical enigma. Its high prevalence and cost to the system warrants attention for improvement. Although, no major recent clinical breakthroughs for resolving back pain have emerged, reducing unnecessary tests, eliminating useless or harmful practices, preventing care dependence, and enhancing coping skills can be useful goals for improving patient outcomes. Quality Improvement (QI) approaches can serve as bridge between clinical intuition and large scale science. Three chiropractic delivery settings including two teaching clinics and one large multidisciplinary spine care center incorporated QI approaches as part of an initiative to improve low back pain care. All clinics were able to implement sustainable process and outcomes improvements.

    Of the multitude of treatment options for the management of neck pain, no obvious single treatment modality has been shown to be most efficacious. As such, the clinician should consider alternative treatment modalities if a modality is engaging, available, financially feasible, potentially efficacious, and is low risk for the patient. As evidence-based medicine for neck pain develops, the clinician is faced with the challenge of which treatments to encourage patients to pursue. Treatment modalities explored in this article, including chiropractic, acupuncture, TENS, massage, yoga, Tai Chi, and Feldenkrais, represent reasonable complementary and alternative medicine methods for patients with neck pain.

  14. The academic legitimization of chiropractic: the case of CMCC and York University

    Grayson, J Paul

    2002-01-01

    Despite the fact that chiropractic has been accepted by more and more Canadians and Americans, it has yet to gain a foothold on a large American or Canadian university campus. In Canada, the primary chiropractic educational institution, the Canadian Memorial Chiropractic College (CMCC), has attempted to affiliate with many universities including the University of Victoria, Brock University, the University of Waterloo, and, most recently, York University. The benefits of association with a university include eligibility for many research grants and academic legitimacy for the profession. While chiropractic has been denied university affiliation, other “subordinate” health occupations, such as nursing and midwifery, are currently taught in Ontario universities. The objective of the current research is to analyse the reasons for the failure of the CMCC to affiliate with York University. The major focus of the investigation is whether CMCC's lack of success can be viewed as a manifestation of the dominance of a medical model at York or whether arguments similar to those raised against CMCC are common in mergers in higher education. The first possibility is consistent with closure theory in general in which professions attempt to limit competition for scarce resources (in this case patients and status), and to the notions of medical dominance and medical sovereignty that are related to closure theory. The second explanation is consistent with “mutual-growth merger theory” in which it is postulated that mergers in higher education are successful when they are of benefit to both parties and a series of steps have been taken ranging from institutional self-assessment, that may involve conducting surveys of the university community, to post-merger consolidation and community building. Overall, it will be argued that the failure of the proposed affiliation is best explained by reference to closure theory, as manifested in medical dominance and medical sovereignty

    Microfluidics, a toolbox comprising methods for precise manipulation of fluids at small length scales (micrometers to millimeters), has become useful for manipulating cells. Its uses range from dynamic management of cellular interactions to high-throughput screening of cells, and to precise analysis of chemical contents in single cells. Microfluidics demonstrates a completely new perspective and an excellent practical way to manipulate cells for solving various needs in biology and medicine. This review introduces and comments on recent achievements and challenges of using microfluidics to manipulate and analyze cells. It is believed that microfluidics will assume an even greater role in the mechanistic understanding of cell biology and, eventually, in clinical applications.

    2014-01-01

    Objective The purpose of this study was to evaluate publicly available information of chiropractic technique systems that advocate radiography for subluxation detection to identify links between chiropractic technique systems and to describe claims made of the health effects of the osseous misalignment component of the chiropractic subluxation and radiographic paradigms. Methods The Internet and publicly available documents were searched for information representing chiropractic technique systems that advocate radiography for subluxation detection. Key phrases including chiropractic, x-ray, radiography, and technique were identified from a Google search between April 2013 and March 2014. Phrases in Web sites and public documents were examined for any information about origins and potential links between these techniques, including the type of connection to BJ Palmer, who was the first chiropractor to advocate radiography for subluxation detection. Quotes were gathered to identify claims of health effects from osseous misalignment (subluxation) and paradigms of radiography. Techniques were grouped by region of the spine and how they could be traced back to B.J Palmer. A genealogy model and summary table of information on each technique were created. Patterns in year of origination and radiographic paradigms were noted, and percentages were calculated on elements of the techniques’ characteristics in comparison to the entire group. Results Twenty-three techniques were identified on the Internet: 6 full spine, 17 upper cervical, and 2 techniques generating other lineage. Most of the upper cervical techniques (14/16) traced their origins to a time when the Palmer School was teaching upper cervical technique, and all the full spine techniques (6/6) originated before or after this phase. All the technique systems’ documents attributed broad health effects to their methods. Many (21/23) of the techniques used spinal realignment on radiographs as one of their outcome

    Objective This study investigates the association between pre-National Board assessments and National Board Part 1 scores (NBCE) at a chiropractic college. Methods A convenience sample of 24 students enrolled in the doctor of chiropractic degree program was recruited for the study. These were 6th and 7th quarter students who had registered to take NBCE in March 2011. Each student's class scores were computed and average numeric means score derived. Subject clusters that make up testable subject categories in NBCE also were computed to obtain a single numeric mean score. Pretests were administered in all areas tested in NBCE. Results were compared to the student's scores in NBCE using correlation and multiple linear regression for 14 predictors and one response variable (NBCE). Results Among the 14 correlations for 19 students (due to missing data when running the correlation matrix), six were moderate-to-strong and statistically significant. Two predictors qualified for multiple linear regression (where n = 22): mean anatomy and mean chemistry, both of which revealed similar regression coefficients. Conclusion Mean anatomy and mean chemistry scores were shown to be the best predictors of NBCE Part 1 results in this sample. PMID:23519085

    Objective: To present a case of primary spontaneous pneumothorax presenting to a chiropractic clinic as undifferentiated thoracic spine pain. Clinical Features: A tall thin 25-year-old male anxiously presented to a chiropractic clinic with six days of sudden unexplained left thorax pain. His breathing was laboured and his dry cough aggravating. After assessment a high clinical suspicion of primary spontaneous pneumothorax prevailed. Intervention and Outcome: The patient was referred to hospital for further investigation and primary spontaneous pneumothorax was confirmed on chest radiograph. He underwent immediate tube thoracostomy to drain the air from his pleural space and to re-inflate his lung. After three days the tube was removed. By two weeks the lung had returned to full size. No recurrences have occurred to date. Conclusions: Primary spontaneous pneumothorax is a medical emergency in the presence of shortness of breath. The focus of treatment is to drain air from the pleural linings and to prevent recurrences. In less severe cases, patients may believe they have thoracic spine pain and seek manual therapy care. This case highlights the important role chiropractors have as primary contact health care providers. PMID:27069268

    Objective This article presents an overview of metabolic syndrome (MetS), which is a collection of risk factors that can lead to diabetes, stroke, and heart disease. The purposes of this article are to describe the current literature on the etiology and pathophysiology of insulin resistance as it relates to MetS and to suggest strategies for dietary and supplemental management in chiropractic practice. Methods The literature was searched in PubMed, Google Scholar, and the Web site of the American Heart Association, from the earliest date possible to May 2014. Review articles were identified that outlined pathophysiology of MetS and type 2 diabetes mellitus (T2DM) and relationships among diet, supplements, and glycemic regulation, MetS, T2DM, and musculoskeletal pain. Results Metabolic syndrome has been linked to increased risk of developing T2DM and cardiovascular disease and increased risk of stroke and myocardial infarction. Insulin resistance is linked to musculoskeletal complaints both through chronic inflammation and the effects of advanced glycosylation end products. Although diabetes and cardiovascular disease are the most well-known diseases that can result from MetS, an emerging body of evidence demonstrates that common musculoskeletal pain syndromes can be caused by MetS. Conclusions This article provides an overview of lifestyle management of MetS that can be undertaken by doctors of chiropractic by means of dietary modification and nutritional support to promote blood sugar regulation.

    Chiropractic and medical colleges have experienced a significant increase in the number of female applicants in recent years, a percentage of whom are pregnant or become pregnant following admission. It is therefore important to ask the question: How do institutions that educate future health care providers address the issue of pregnancy and the gross anatomy laboratory? A survey instrument was developed and pretested. IRB approval was obtained. The administrators charged with overseeing the policies and practices for the gross anatomy laboratory at each of the 16 chiropractic colleges in the USA were identified and contacted. An email containing a link to the Web based survey was sent to each, using SurveyMonkey. The survey response rate was 100%. A majority of colleges (69%) have a written policy regarding pregnancy and the gross laboratory. Of these, 36% allow pregnant students to take the laboratory if a waiver is signed, 18% do not allow them to take the laboratory, 18% allow them to take it without a waiver, and 27% have other policies. In cases where students do not take the gross laboratory while pregnant, 64% of colleges require them to take the laboratory after completion of their pregnancy, 27% require them to complete an alternative (dry) laboratory, and 9% have other policies. Considerable diversity exists in the way colleges address this issue. It is at present unknown whether pregnant students or their fetuses are at any risk from laboratory chemicals. Risk assessment research is needed before consistent policies can be developed.

    1985-09-01

    X-raying the entire spinal column in the standing position in a single exposure (mainly the AP projection) is an often-used chiropractic radiography procedure which has also found some application in medical scoliosis screening program. Aside from any controversy of clinical objectives or medical necessity, the primary agreed-upon requisite for such procedure is twofold; achieving the best possible film image quality with the least amount of radiation exposure to the patient. A popular method of accomplishing this objective is by the use of collimator-attached devices designed to selectively filter the primary x-ray beam in accordance with regional variations of body thickness and/or density. This study was conducted to evaluate the use of a new lead-acrylic filter system under specialized chiropractic conditions. In comparison to other available systems, it was concluded that this new system; a) is generally equivalent in its radiation dose reduction capabilities; b) is capable of producing full spine radiographs with good to above average image quality; and c) is appreciably easier to use.

    Introduction: The process by which the jurisprudence course was restructured at the Canadian Memorial Chiropractic College is chronicled. Method: A Delphi process used to restructure the course is described, and the results of a student satisfaction survey are presented. Results: When asked “I think this material was clinically relevant,” over 81% of the 76 students who respondents strongly agreed or agreed with this statement; 100% of students agreed or strongly agreed that scope of practice; marketing, advertising and internal office promotion; record keeping; fee schedules; malpractice issues and; professional malpractice issues and negligence was clinically relevant. When asked “I think this material was taught well,” a minimum of 89% of students agreed or strongly agreed with this statement. Discussion: This is the first article published that described the process by which a jurisprudence course was developed and assessed by student survey. Summary: Based on a survey of student perceptions, restructuring of the jurisprudence course was successful in providing students with clinically relevant information in an appropriate manner. This course may serve as an important first step in development a ‘model curriculum’ for chiropractic practice and the law courses in terms of content, format and assessment strategies.

    Abstract Objective To determine if there is a greater yield of pathological findings identified on MRI scans of patients referred by chiropractors as compared to those referred by allopathic providers. Methods MRI reports authored by medical radiologists from two independent MRI centers in the Denver metropolitan area were analyzed retrospectively for pathological data related to the spinal regions studied. A pathological report data sheet was used to record pathological findings in 22 different categories. A total of 150 reports from each provider group were reviewed. Results Of the 22 pathological conditions studied, a statistically significant difference between doctor of chiropractic and medical doctor referrers was identified in 4 categories: central spinal canal stenosis, lateral stenosis, facet arthrosis, and negative report. The most common primary diagnoses given for MRI referral were low back pain/sciatica, neck pain, and extremity pain. Seventy-four percent of the reports evaluated were performed on patients referred with a diagnosis of pain. In 3 of the 22 categories (14%), the medical doctors had a statistically higher pathological yield than the chiropractors. However, in 4 of the 22 categories (18%), the chiropractors had a statistically higher pathological yield. In 18 of the 22 categories (82%), there was no statistical difference between the two provider groups. Conclusion The data presented in this study suggests chiropractic and medical providers are compeer at ordering MRI for suspected pathological findings. PMID:19674677

    Cadavers play an important role in anatomy education. In Australia, bodies for anatomy education are acquired only through donations. To gain insight into educational dynamics in an anatomy laboratory as well as to facilitate body donation programs and thanksgiving ceremonies, it is important to understand students' attitudes toward body donation. In this cross-sectional study, the attitudes of Macquarie University's first, second, and fifth year chiropractic students toward body donation were investigated. Macquarie University chiropractic students have a four semester long anatomy program, which includes cadaver-based instruction on prosected specimens. A questionnaire was used to record respondents' demographics and attitudes toward body donation: personal, by a relative, and by a stranger. It was found that ethnicity and religion affect attitudes toward body donation, with Australian students being more willing to donate a stranger's body and atheists and agnostics being more willing to donate in general. Furthermore, willingness to donate one's own or a family member's body decreases as year of study increases, suggesting a possible negative impact of exposure to cadavers in the anatomy laboratory. This was only true, however, after controlling for age. Thus, the impact of viewing and handling prosected specimens, which is the norm in anatomy classes in Australia, may not be as strong as dissecting cadavers. It is suggested that anatomists and educators prepare students for cadaver-based instruction as well as exhibit sensitivity to cultural differences in how students approach working with cadavers, when informing different communities about body donation programs and in devising thanksgiving ceremonies.

    The Manipulator Comparative Testing Program examined differences among manipulator systems from the United States and Japan. The manipulator systems included the Meidensha BILARM 83A, the Model M-2 of Central Research Laboratories Division of Sargent Industries (CRL), and the GCA Corporation PaR Systems Model 6000. The site of testing was the Remote Operations Maintenance Demonstration (ROMD) facility, operated by the Fuel Recycle Division in the Consolidated Fuel Reprocessing Program at the Oak Ridge National Laboratory (ORNL). In all stages of testing, operators using the CRL Model M-2 manipulator had consistently lower times to completion and error rates than they did using other machines. Performance was second best with the Meidensha BILARM 83A in master-slave mode. Performance with the BILARM in switchbox mode and the PaR 6000 manipulator was approximately equivalent in terms of criteria recorded in testing. These data show no impact of force reflection on task performance.

    2013-06-01

    Recent advances in the lab-on-a-chip field in association with nano/microfluidics have been made for new applications and functionalities to the fields of molecular biology, genetic analysis and proteomics, enabling the expansion of the cell biology field. Specifically, microfluidics has provided promising tools for enhancing cell biological research, since it has the ability to precisely control the cellular environment, to easily mimic heterogeneous cellular environment by multiplexing, and to analyze sub-cellular information by high-contents screening assays at the single-cell level. Various cell manipulation techniques in microfluidics have been developed in accordance with specific objectives and applications. In this review, we examine the latest achievements of cell manipulation techniques in microfluidics by categorizing externally applied forces for manipulation: (i) optical, (ii) magnetic, (iii) electrical, (iv) mechanical and (v) other manipulations. We furthermore focus on history where the manipulation techniques originate and also discuss future perspectives with key examples where available.

  14. Osteopathic Manipulative Treatment

    Campbell, Shannon M.; Walkowski, Stevan

    2012-01-01

    Dermatological diseases, such as dysesthesia syndromes, stasis dermatoses, and hyperhidrosis are difficult to treat due to their complex etiologies. Current theories suggest these diseases are caused by physiological imbalances, such as nerve impingement, localized tissue congestion, and impaired autonomic regulation. Osteopathic manipulative therapy targets these physiological dysfunctions and may serve as a beneficial therapeutic option. Osteopathic manipulative therapy techniques include high velocity low amplitude, muscle energy, counterstrain, myofascial release, craniosacral, and lymphatic drainage. An osteopathic manipulative therapy technique is chosen based on its physiological target for a particular disease. Osteopathic manipulative therapy may be useful alone or in combination with standard therapeutic options. However, due to the lack of standardized trials supporting the efficacy of osteopathic manipulative therapy treatment for dermatological disease, randomized, well-controlled studies are necessary to confirm its therapeutic value.

    Objective The purpose of this case study is to describe the treatment using acupuncture and spinal manipulation for a patient with a chronic tension-type headache and episodic migraines. Clinical Features A 32-year-old woman presented with headaches of 5 months' duration. She had a history of episodic migraine that began in her teens and had been controlled with medication. She had stopped taking the prescription medications because of gastrointestinal symptoms. A neurologist diagnosed her with mixed headaches, some migrainous and some tension type. Her headaches were chronic, were daily, and fit the International Classification of Headache Disorders criteria of a chronic tension-type headache superimposed with migraine. Intervention and Outcome After 5 treatments over a 2-week period (the first using acupuncture only, the next 3 using acupuncture and chiropractic spinal manipulative therapy), her headaches resolved. The patient had no recurrences of headaches in her 1-year follow-up. Conclusion The combination of acupuncture with chiropractic spinal manipulative therapy was a reasonable alternative in treating this patient's chronic tension-type headaches superimposed with migraine.

    The temporomandibular pain-dysfunction syndrome (TMJ-PDS) is a frequent but often unappreciated cause of head, neck, and facial pain. Information regarding its etiology, pathophysiology, diagnosis, and treatment is fragmentary, and often reflects an approach influenced by the background specialty of the involved practitioner. Current treatment is often multidisciplinary, involving the use of various dental splints in conjunction with physiotherapy, psychotherapy, and analgesic medication. This paper suggests that chiropractic manipulation to the temporomandibular joints (TMJ) may be an effective approach to treatment of TJM-PDS. Illustrative cases are presented.

    The aim of this study was to evaluate the radiographic outcomes obtained in a sample of patients treated with a chiropractic scoliosis-specific exercise program for patients with adolescent idiopathic scoliosis. Patients were treated and subsequently followed through skeletal maturity, and their results were reported in accordance with the SOSORT Consensus Guidelines. A total of 60 patient charts were consecutively selected when they met inclusion criteria. Cobb angle measurements and Risser staging were collected on all images. Using SOSORT criteria, 51.7% of patients achieved curve correction and 38.3% achieved stabilization. In the curve correction group, average total correction was 12.75°. A small number of sampled patients’ curves progressed, with a 13% failure rate based upon patients who dropped out before skeletal maturity combined with those who had progressed at skeletal maturity. Future studies are needed to corroborate these observations. PMID:28243430

    This paper presents a proposed quality assurance (QA) program for chiropractors using surface electromyography (SEMG) in their offices. The paper examines in detail the various aspects of the program including both the technical and professional components. The technical component has three sub topics: equipment, technical procedures and data processing; as does the professional component: qualification/certification, compliance/peer review and patient selection. These are also further broken down to discuss the aspects dealing with quality and also other basic components necessary to understand the effective use of SEMG in the chiropractic office. The rationale for such a program is presented first and the details of the various aspects later. The complete program is represented in a number of charts which form a blueprint for the total QA program. As this is a proposed program, the authors invite feedback and criticism so that it may be optimized.

    Questionnaires covering health and the use of complementary, alternative and conventional health services were mailed to a random sample of 14 868 adults aged 18-64 years living in four counties of England in 1997. The present study examined the use of osteopathy/chiropractic among the 15% (n = 1377) of respondents reporting back pain. Osteopaths/chiropractors were seen by 13.4% (n = 184) of respondents with back pain during the past 3 months compared with 9.8% (n = 135) who consulted physiotherapists. The presence of back pain and non-manual social class were the strongest predictors of consultation with both types of practitioner. Women, older respondents, non-smokers and those who exercised for 30 minutes at least once a week were more likely to use osteopathy/chiropractic. The only other significant predictor of physiotherapy use was desire for more physical exercise. While those reporting back pain had Short-Form 36 (SF-36) scores suggesting very significant levels ofdisability, respondents with back pain who consulted osteopaths/chiropractors reported better health in all dimensions of the SF-36 than those using physiotherapy services. Although they reported worse pain scores than people not consulting any practitioners, their mental health, physical functioning, energy and health perception were better. It is impossible to disentangle cause and effect in this cross-sectional study, but the data suggest that people who can afford to pay are more likely to choose osteopath/chiropractor treatments than physiotherapy. The possibility that osteopath/chiropractor treatment has a generalised positive effect on health, allowing people with back pain to function better than those not receiving such treatment, warrants further investigation.

    Objective : Although tobacco cessation training is included in many health profession programs, it is not yet routinely incorporated into chiropractic education. The purpose of this study was to assess the feasibility of incorporating a problem-based learning tobacco cessation activity into a lecture course for chiropractic students. Methods : Seventy-two students were assigned to participate in two 1-hour lectures on health promotion counseling and tobacco cessation followed by an experiential student-driven lab session using standardized patients at various stages of dependency and willingness to quit. The intervention was based on the transtheoretic model and the "5 A's" of counseling (ask, advise, assess, assist, arrange). Outcomes were assessed via (1) questionnaires completed by the standardized patients regarding the students' use of the 5A's, and (2) questionnaires completed by the students using a 5-point Likert scale of "strongly disagree" to "strongly agree" on the acceptability of this method of learning. Descriptive statistics were computed. Results : Sixty-eight students (94%) completed the activity, spending a median of 2.5 minutes with patients. Over 90% addressed 4 of the 5A's: 99% asked patients if they were smokers; 97% advised them to quit; 90% assessed if they were willing to quit; and 99% offered assistance in quitting. Only 79% arranged a follow-up visit. Overall, students expressed a positive response to the experience; 81% said it increased their confidence in being able to advise patients, and 77% felt it would be valuable for use in their future practice. Conclusion : This active learning exercise appeared to be a feasible way to introduce tobacco counseling into the curriculum.

    Objective Patients who use complementary and integrative health services like chiropractic manipulative treatment (CMT) often have different characteristics than patients who do not, and these differences can confound attempts to compare outcomes across treatment groups, particularly in observational studies when selection bias may occur. The purposes of this study were to provide an overview on how propensity scoring methods can be used address selection bias by balancing treatment groups on key variables and to use Medicare data to compare different methods for doing so. Methods We described 2 propensity score methods (matching and weighting). Then we used Medicare data from 2006-2012 on older, multiply comorbid patients who had a chronic low back pain episode to demonstrate the impact of applying methods on the balance of demographics of patients between 2 treatment groups (those who received only CMT and those who received no CMT during their episodes). Results Before application of propensity score methods, patients who used only CMT had different characteristics from those who did not. Propensity score matching diminished observed differences across the treatment groups at the expense of reduced sample size. However, propensity score weighting achieved balance in patient characteristics between the groups and allowed us to keep the entire sample. Conclusions While propensity score matching and weighting have similar effects in terms of balancing covariates, weighting has the advantage of maintaining sample size, preserving external validity, and generalizing more naturally to comparisons of 3 or more treatment groups. Researchers should carefully consider which propensity score method to use, as using different methods can generate different results. PMID:26547763

    Inertial force damping control by micro manipulator modulation is proposed to suppress the vibrations of a micro/macro manipulator system. The proposed controller, developed using classical control theory, is added to the existing control system. The proposed controller uses real-time measurements of macro manipulator flexibility to adjust the motion of the micro manipulator to counteract structural vibrations. Experimental studies using an existing micro/macro flexible link manipulator testbed demonstrate the effectiveness of the proposed approach to suppression of vibrations in the macro/micro manipulator system using micro-manipulator-based inertial active damping control.

The objective of this study was to determine the interrater reliability of the OSPE in measuring the clinical reasoning ability of chiropractic students. Methods: Two examiners tested each student simultaneously when enough were available as a check for interrater reliability. The scores for students over 4 exam administrations were compiled, and we calculated an intraclass correlation coefficient (ICC) using 1-way random single measures. Results: Paired scores were available for 133 students. The ICC was .685, showing a fair-to-good level of agreement for faculty in assessing the clinical reasoning ability of chiropractic students using an OSPE. Conclusion: The OSPE can be a valuable tool for testing clinical reasoning abilities because it can simulate the decision-making process that needs to be implemented in clinical practice. Faculty members at our chiropractic college were able to achieve an acceptable level of reliability in measuring the clinical reasoning abilities of students using an OSPE. Other health professional programs may consider using this tool for assessing the clinical reasoning skills of their students. PMID:27115474

    Objectives: To identify Canadian chiropractors’ attitudes, skills and use of evidence based practice (EBP), as well as their level of awareness of previously published chiropractic clinical practice guidelines (CPGs). Methods: 7,200 members of the Canadian Chiropractic Association were invited by e-mail to complete an online version of the Evidence Based practice Attitude & utilisation SurvEy (EBASE); a valid and reliable measure of participant attitudes, skills and use of EBP. Results: Questionnaires were completed by 554 respondents. Most respondents (>75%) held positive attitudes toward EBP. Over half indicated a high level of self-reported skills in EBP, and over 90% expressed an interest in improving these skills. A majority of respondents (65%) reported over half of their practice was based on evidence from clinical research, and only half (52%) agreed that chiropractic CPGs significantly impacted on their practice. Conclusions: While most Canadian chiropractors held positive attitudes towards EBP, believed EBP was useful, and were interested in improving their skills in EBP, many did not use research evidence or CPGs to guide clinical decision making. Our findings should be interpreted cautiously due to the low response rate. PMID:26816412

    Abstract Objective The purpose of this paper is to present a case of a child with Prader-Willi syndrome and the observed improvement in the degree of scoliosis, immune function, and behavior documented during the course of her treatment. Clinical Features A 7-year-old girl presented to Kentuckiana Children's Center with a 15° lumbar levoscoliosis and diagnosis of Prader-Willi syndrome. Intervention and Outcome The treatment plan consisted of chiropractic adjustments, craniosacral therapy, movement therapy, and nutritional therapy. Over the course of treatment, her muscle strength, tone, and motor activity increased. She improved in coordination of gait and balance. Over the course of 3 years, her scoliosis decreased to 4° to 5°. Improvements in immune function and a reduction in anxiety type behaviors were documented by the parents and doctor of chiropractic over the course of 5 years. Conclusions This case report describes the improvements and progression of one female child with Prader-Willi syndrome under chiropractic and multidisciplinary care. PMID:19948310

    Objective The chiropractic profession is immersed in the process of professionalization with particular consideration of self-regulation as an avenue toward state recognition in Singapore. The purpose of this article is to discuss the emergence of chiropractic as a profession in Singapore and the Chiropractic Association (Singapore). Discussion The concept of professionalization is varied and context based, and the institutionalization of formal knowledge plays an important role in the socialization of how a profession forms a unifying identity. The difference in institutional socialization of the professions plays a role in the way a profession is perceived in the hierarchy of societal power. Continuing professional development is an essential part of professionalism and is best done within the realm of self-regulation and autonomous control of the profession itself. Conclusion The social process of professionalization can be a process of internal conflict and external battles almost from the profession's inception with university training only entering late in its development, rather than being a linear development. A sequential progress ensued as with other professions, with the seeking of legal protection and a code of ethics as the final areas reached toward becoming an acknowledged member of the health care system.

    2015-01-01

    Objective The purpose of this case report is to describe chiropractic management of an elderly man with untreated bilateral hip joint dysplasia presenting with mild acute mechanical low back pain. Clinical Features A 75-year-old man presented with an insidious-onset intermittent low back pain of 3 days’ duration. Physical examination findings supported a mechanical cause for mild acute low back pain. Plain radiography revealed dysplasia of hip joints with absence of femoral heads and necks and bilateral high dislocation. Intervention and Outcome Chiropractic management included vibration, mobilization, light drop-piece adjustments of the lower lumbar and sacroiliac joints, and recommendation of the use of heat at home. Treatments were given 3 times over the course of 1 week. The low back pain intensity over this period dropped from 5 to 0 on an 11-point numerical rating scale, and the patient was discharged. Conclusion This patient with substantial postural and gait abnormalities as a result of severe bilateral hip dysplasia associated with an unusual pattern of osteoarthritic change in the spine responded favorably to a short course of chiropractic care.

    In a previous article, the author reported on the recommendations gathered from student projects between 1996 and 1999 investigating their preferences for including certain chiropractic Name technique systems into the curriculum at the Canadian Memorial Chiropractic College (CMCC). These results were found to be congruent with the professional treatment technique used by Canadian chiropractors. This article reports on the data obtained during the 2000 and 2001 academic years, comparing these results to those previously gathered. In addition, because of the implementation of a new curriculum during this time period, there was unique opportunity to observe whether or not student perceptions differed between those students in the `old' curricular program, and those students in the `new' curricular program. The results gathered indicate that students in both curricular programs show an interest in learning Thompson Terminal Point, Activator Methods, Gonstead, and Active Release Therapy techniques in the core curriculum, as an elective, or during continuing educational programs provided by the college. Students continue to show less interest in learning CranioSacral Therapy, SacroOccipital Technique, Logan Basic, Applied Kinesiology and Chiropractic BioPhysics. Over time, student interest has moved away from Palmer HIO and other upper cervical techniques, and students show a declining interest in being offered instruction in either Network Spinal Analysis or Torque Release Techniques. Since these findings reflect the practice activities of Canadian chiropractors they may have implications not only towards pedagogical decision-making processes at CMCC, but they may also influence professional standards of care.

    This paper describes Oak Ridge National Laboratory`s development of an environment for the simulation of robotic manipulators. Simulation includes the modeling of kinematics, dynamics, sensors, actuators, control systems, operators, and environments. Models will be used for manipulator design, proposal evaluation, control system design and analysis, graphical preview of proposed motions, safety system development, and training. Of particular interest is the development of models for robotic manipulators having at least one flexible link. As a first application, models have been developed for the Pacific Northwest Laboratories` Flexible Beam Testbed which is a one-Degree-Of-Freedom, flexible arm with a hydraulic base actuator. Initial results show good agreement between model and experiment.

    1989-01-01

    The feasibility of using model based control (MBC) for robotic manipulators was investigated. A double inverted pendulum system was constructed as the experimental system for a general study of dynamically stable manipulation. The original interest in dynamically stable systems was driven by the objective of high vertical reach (balancing), and the planning of inertially favorable trajectories for force and payload demands. The model-based control approach is described and the results of experimental tests are summarized. Results directly demonstrate that MBC can provide stable control at all speeds of operation and support operations requiring dynamic stability such as balancing. The application of MBC to systems with flexible links is also discussed.

    A remote control manipulator is described in which the master and slave arms are electrically connected to produce the desired motions. A response signal is provided in the master unit in order that the operator may sense a feel of the object and may not thereby exert such pressures that would ordinarily damage delicate objects. This apparatus will permit the manipulation of objects at a great distance, that may be viewed over a closed TV circuit, thereby permitting a remote operator to carry out operations in an extremely dangerous area with complete safety.

  1. English language proficiency and the accommodations for language non-concordance amongst patients utilizing chiropractic college teaching clinics

    PubMed Central

    2013-01-01

    Background The number of households in the United States that are not proficient in the English language is growing and presenting a challenge to the health care system. Over nineteen percent of the US population speak a language other than English in the home. This increase in language discordance generates a greater need to find and implement accommodations in the clinical setting to insure accurate and efficient diagnosis and treatment as well as provide for patient safety. Aim: The purpose of this study is to determine the percentage of patients accessing the chiropractic college teaching clinics who are not proficient in the English language and to what extent the colleges provide accommodations for that language disparity. Methods The clinic directors and deans of the Association of Chiropractic Colleges were surveyed via an on-line survey engine. The survey queried the percentage of the patient population that is not English language proficient, the accommodations the college currently has in place, if the college has a language specific consent to treat document and if the college has a written policy concerning patients without English proficiency. Results Fifty percent of the contacted chiropractic colleges responded to the survey. In the respondent college clinics 16.5% of the patient population is not proficient in English, with over 75% speaking Spanish. All but one of the respondents provide some level of accommodation for the language non-concordance. Forty five percent of the responding colleges employ a language specific consent to treat form. The implementation of accommodations and the use of a language specific consent to treat form is more prevalent at colleges with a higher percentage of non-English speaking patients. Conclusions The percentage of patients with limited English proficiency accessing services at the teaching clinics of the chiropractic colleges mirrors the numbers in the general population. There is a wide disparity in the

    Purpose: The purpose of this study was to pilot test our study procedures and estimate parameters for sample size calculations for a randomized controlled trial to determine if bilateral sacroiliac (SI) joint manipulation affects specific gait parameters in asymptomatic individuals with a leg length inequality (LLI). Methods: Twenty-one asymptomatic chiropractic students engaged in a baseline 90-second walking kinematic analysis using infrared Vicon® cameras. Following this, participants underwent a functional LLI test. Upon examination participants were classified as: left short leg, right short leg, or no short leg. Half of the participants in each short leg group were then randomized to receive bilateral corrective SI joint chiropractic manipulative therapy (CMT). All participants then underwent another 90-second gait analysis. Pre- versus post-intervention gait data were then analyzed within treatment groups by an individual who was blinded to participant group status. For the primary analysis, all p-values were corrected for multiple comparisons using the Bonferroni method. Results: Within groups, no differences in measured gait parameters were statistically significant after correcting for multiple comparisons. Conclusions: The protocol of this study was acceptable to all subjects who were invited to participate. No participants refused randomization. Based on the data collected, we estimated that a larger main study would require 34 participants in each comparison group to detect a moderate effect size. PMID:24587501

    1987-01-01

    Research on control, design and programming of kinematically redundant robot manipulators (KRRM) is discussed. These are devices in which there are more joint space degrees of freedom than are required to achieve every position and orientation of the end-effector necessary for a given task in a given workspace. The technological developments described here deal with: kinematic programming techniques for automatically generating joint-space trajectories to execute prescribed tasks; control of redundant manipulators to optimize dynamic criteria (e.g., applications of forces and moments at the end-effector that optimally distribute the loading of actuators); and design of KRRMs to optimize functionality in congested work environments or to achieve other goals unattainable with non-redundant manipulators. Kinematic programming techniques are discussed, which show that some pseudo-inverse techniques that have been proposed for redundant manipulator control fail to achieve the goals of avoiding kinematic singularities and also generating closed joint-space paths corresponding to close paths of the end effector in the workspace. The extended Jacobian is proposed as an alternative to pseudo-inverse techniques.

    2008-04-01

    As unmanned systems become more commonplace in military, police, and other security forces, they are tasked to perform missions that the original hardware was not designed for. Current military robots are built for rough outdoor conditions and have strong inflexible manipulators designed to handle a wide range of operations. However, these manipulators are not well suited for some essential indoor tasks, including opening doors. This is a complicated kinematic task that places prohibitively difficult control challenges on the robot and the operator. Honeybee and iRobot have designed a modular door-breaching manipulator that mechanically simplifies the demands upon operator and robot. The manipulator connects to the existing robotic arm of the iRobot PackBot EOD. The gripper is optimized for grasping a variety of door knobs, levers, and car-door handles. It works in conjunction with a compliant wrist and magnetic lock-out mechanism that allows the wrist to remain rigid until the gripper has a firm grasp of the handle and then bend with its rotation and the swing of the door. Once the door is unlatched, the operator simply drives the robot through the doorway while the wrist compensates for the complex, multiple degree-of-freedom motion of the door. Once in the doorway the operator releases the handle, the wrist pops back into place, and the robot is ready for the next door. The new manipulator dramatically improves a robot's ability to non-destructively breach doors and perform an inspection of a room's content, a capability that was previously out of reach of unmanned systems.

    1996-01-01

    Data derived from the administration of the Canadian Chiropractic Examining Board (CCEB) examinations for a nine year period, 1987-1995, were used to evaluate the reliability and validity of the subject tests: anatomy, chemistry, chiropractic practice, diagnosis and symptomatology, microbiology and public health, neurology, pathology, physiology, and x-ray interpretation and physics. Nearly two-thousand candidates from more than eighteen chiropractic colleges have written the CCEB exams over this nine year period. The results indicate that the exams have adequate alpha reliabilities (.69 to .80) and theoretically appropriate statistical properties and item characteristics. There is also substantial evidence of content validity. Results from stepwise multiple regression and factor analyses provided evidence for the criterion-related and construct validity of the exams. The implication of these results for the continued refinement and development of the CCEB exams, together with suggestions for on-going research of their reliability and validity, are discussed.

    A manipulator is described for performing, within an entirely enclosed cell containling radioactive materials, various mechanical operations. A rod with flexible fingers is encompassed by a tubular sleeve shorter than the rod. Relative movement between the rod and sleeve causes the fingers to open and close. This relative movement is effected by relative movement of permanent magnets in magnetic coupling relation to magnetic followers affixed to the ends of the rod and sleeve. The rod and its sleeve may be moved as a unit axially or may be rotated by means of the magnetic couplings. The manipulator is enclosed within a tubular member which is flexibly sealed to an opening in the cell. (AEC)

  16. A health care system in transformation: making the case for chiropractic

    PubMed Central

    2012-01-01

    There are a number of factors that have conspired to create a crisis in healthcare. In part, the successes of medical science and technologies have been to blame, for they have led to survival where lives would previously have been cut short. An informed public, aware of these technological advances, is demanding access to the best that healthcare has to offer. At the same time the burden of chronic disease in an increasing elderly population has created a marked growth in the need for long term care. Current estimates for expenditure predict a rapid escalation of healthcare costs as a proportion of the GDP of developed nations, yet at the same time a global economic crisis has necessitated dramatic cuts in health budgets. This unsustainable position has led to calls for an urgent transformation in healthcare systems. This commentary explores the present day healthcare crisis and looks at the opportunities for chiropractors as pressure intensifies on politicians and leaders in healthcare to seek innovative solutions to a failing model. Amidst these opportunities, it questions whether the chiropractic profession is ready to accept the challenges that integration into mainstream healthcare will bring and identifies both pathways and potential obstacles to acceptance.

    2014-10-01

    Objective : The objective of this study was to investigate the association of a clinical documentation quality improvement program using audit-feedback with clinical compliance to indicators of quality chart documentation. Methods : This was an analysis of differences between adherence to quality indicators of chiropractic record documentation and audit-feedback intervention (feedback report only vs. feedback report with one-on-one educational consultation) at different campuses. Comparisons among groups were analyzed using analysis of variance (ANOVA), Tukey or Dunnett post hoc tests, and Cohen's d effect size estimates. Results : There was a significant increase in the mean percentile compliance in 2 of 5 compliance areas and 1 of 11 compliance objectives. Campus B demonstrated significantly higher levels of compliance relative to campus A and/or campus C in 5 of 5 compliance areas and 7 of 11 compliance objectives. Across-campus comparisons indicated that the compliance area Review (Non-Medicare) Treatment Plan [F(2,18) = 17.537, p < .001] and compliance objective Treatment Plan Goals [F(2,26) = 5.653, p < .001] exhibited the highest practical importance for clinical compliance practice. Conclusions : Feedback of performance improved compliance to indicators of quality health record documentation, especially when baseline adherence is relatively low. Required educational consultations with clinicians combined with audit-feedback were no more effective at increasing compliance to indicators of quality health record documentation than audit-feedback alone.

    2015-01-01

    Objective The aim of the study was twofold: (1) to compare the perceived educational environment at 2 points in time and (2) to longitudinally examine potential changes in perceptions of the educational environment over time. Methods The validated Dundee Ready Educational Environment Measure (DREEM), a 50-item, self-administered Likert-type inventory, was used in this prospective study. Employing convenience sampling, undergraduate chiropractic students were investigated at 2 points in time: 2009 (n = 124) and 2012 (n = 127). An analysis of 2 matching samples was performed on 27% (n = 34) of the respondents in 2009. Results A total of 251 students (79%) completed the inventory, 83% (n = 124) in 2009 and 75% (n = 127) in 2012. The overall DREEM scores in both years were excellent: 156 (78%) and 153 (77%), respectively. The students' perceptions of teachers differed significantly between the 2 cohort years, decreasing from 77% to 73%. Three items received deprived scores: limited support for stressed students, authoritarian teachers, and an overemphasis on factual learning; the latter significantly decreased in 2012. In the longitudinal sample these items also displayed scores below the expected mean. Conclusion Students viewed the educational environment as excellent both in 2009 and 2012. The perceptions of teachers declined with time; however, this could be attributed to teachers' new roles. Certain aspects of the educational environment factored prominently during the comparative points in time, as well as longitudinally, and these ought to be further investigated and addressed to provide an enhanced educational environment.

    Objective : Stress encompasses academic issues, such as time management, increased work load, and new subject matter, but cannot be separated from stressors, such as social adjustment and financial pressure. Our study investigated whether perceived level of academic or practical attainment and the method of study were associated with the amount of perceived stress during students" studies. Methods : A semi-structured self-administered questionnaire was piloted and distributed to 134 students at a chiropractic college at the end of a lecture. Results : The survey had a response rate of 81%. Students in their fourth year consistently reported the highest perceived levels of stress, with 81% feeling that their ability to study was affected by their financial situation and 56% felt overwhelmed at their ability to cope with their college workload. All year groups were stressed during their course of studies, but the stressor varies depending on the year of study. Conclusions : Year 4 consistently demonstrated the highest levels of stress. All students, regardless of year group, experienced varying degrees of stress while studying and the central stressor changed depending on the time position within the course.

    We developed two similar structure manipulators for medical endocavity ultrasound probes with 3 and 4 degrees of freedom (DoF). These robots allow scanning with ultrasound for 3-D imaging and enable robot-assisted image-guided procedures. Both robots use remote center of motion kinematics, characteristic of medical robots. The 4-DoF robot provides unrestricted manipulation of the endocavity probe. With the 3-DoF robot the insertion motion of the probe must be adjusted manually, but the device is simpler and may also be used to manipulate external-body probes. The robots enabled a novel surgical approach of using intraoperative image-based navigation during robot-assisted laparoscopic prostatectomy (RALP), performed with concurrent use of two robotic systems (Tandem, T-RALP). Thus far, a clinical trial for evaluation of safety and feasibility has been performed successfully on 46 patients. This paper describes the architecture and design of the robots, the two prototypes, control features related to safety, preclinical experiments, and the T-RALP procedure. PMID:24795525

    1994-01-01

    The present invention is directed to a welding nozzle position manipulator. The manipulator consists of an angle support to which the remaining components of the device are attached either directly or indirectly. A pair of pivotal connections attach a weld nozzle holding link to the angle support and provide a two axis freedom of movement of the holding link with respect to the support angle. The manipulator is actuated by a pair of adjusting screws angularly mounted to the angle support. These screws contact a pair of tapered friction surfaces formed on the upper portion of the welding nozzle holding link. A spring positioned between the upper portions of the support angle and the holding link provides a constant bias engagement between the friction surfaces of the holding link and the adjustment screws, so as to firmly hold the link in position and to eliminate any free play in the adjustment mechanism. The angular relationships between the adjustment screws, the angle support and the tapered friction surfaces of the weld nozzle holding link provide a geometric arrangement which permits precision adjustment of the holding link with respect to the angle support and also provides a solid holding link mount which is resistant to movement from outside forces.

The manipulator consists of an angle support to which the remaining components of the device are attached either directly or indirectly. A pair of pivotal connections attach a weld nozzle holding link to the angle support and provide a two axis freedom of movement of the holding link with respect to the support angle. The manipulator is actuated by a pair of adjusting screws angularly mounted to the angle support. These screws contact a pair of tapered friction surfaces formed on the upper portion of the welding nozzle holding link. A spring positioned between the upper portions of the support angle and the holding link provides a constant bias engagement between the friction surfaces of the holding link and the adjustment screws, so as to firmly hold the link in position and to eliminate any free play in the adjustment mechanism. The angular relationships between the adjustment screws, the angle support and the tapered friction surfaces of the weld nozzle holding link provide a geometric arrangement which permits precision adjustment of the holding link with respect to the angle support and also provides a solid holding link mount which is resistant to movement from outside forces.

    The mother of a 3-month old girl presented her daughter for chiropractic care with a medical diagnosis of gastroesophageal reflux disease. Her complaints included frequently interrupted sleep, excessive intestinal gas, frequent vomiting, excessive crying, difficulty breastfeeding, plagiocephaly and torticollis. Previous medical care consisted of Prilosec prescription medication. Notable improvement in the patient’s symptoms was observed within four visits and total resolution of symptoms within three months of care. This case study suggests that patients with complaints associated with both musculoskeletal and non-musculoskeletal origin may benefit from chiropractic care. PMID:19066699

  6. Adverse events from spinal manipulation in the pregnant and postpartum periods: a critical review of the literature

    PubMed Central

    2012-01-01

    Background The safety of spinal manipulation during pregnancy and the postpartum periods has been a matter of debate among manual therapists. Spinal manipulative therapy during these periods is a commonly performed intervention as musculoskeletal pain is common in these patients. To date there has not been an evaluation of the literature on this topic exclusively. Methods A literature search was conducted on PubMed, CINAHL and the Index to Chiropractic Literature along with reference searching for articles published in English and French in the peer-reviewed literature that documented adverse effects of spinal manipulation during either pregnancy or postpartum. Case reports, case series, and any other clinical study designs were deemed acceptable for inclusion, as were systematic reviews. The appropriate Scottish Intercollegiate Guidelines Network (SIGN) tools were used to rate included articles for quality when applicable. Results Five articles identifying adverse events in seven subjects following spinal manipulation were included in this review, along with two systematic reviews. The articles were published between 1978 and 2009. Two articles describing adverse effects from spinal manipulation on two postpartum patients were included, while the remaining three articles on five patients with adverse effects following spinal manipulation were on pregnant patients. Injury severity ranged from minor injury such as increasing pain after treatment that resolved within a few days to more severe injuries including fracture, stroke, and epidural hematoma. SIGN scores of the prospective observational cohort study and systematic reviews indicated acceptable quality. Conclusions There are only a few reported cases of adverse events following spinal manipulation during pregnancy and the postpartum period identified in the literature. While improved reporting of such events is required in the future, it may be that such injuries are relatively rare. PMID:22455720

    Objective The purpose of this study was to describe non-Hispanic blacks that use chiropractic health care to better understand this underserved demographic. Methods E-mail and telephone calls were used to recruit doctors of chiropractic (DCs) in Texas and Louisiana to distribute anonymous surveys to their non-Hispanic black patients. Twenty doctors volunteered to participate. Each was sent 10 surveys and self-addressed envelopes to distribute. All doctors were given at least 3 months to distribute surveys to as many non-Hispanic black patients that they had. The survey contained 20 questions designed to develop a profile of non-Hispanic black patients that used chiropractic care. Descriptive statistics were used to summarize demographic and other patient attributes. Results Two-hundred surveys were distributed and 44 were completed, yielding a response rate of 22%. Non-Hispanic black patients were more likely to be female (54.5%), be older than 50 years (56.8%), be a college graduate (59.1%), be employed (61.9%), report not receiving public assistance in the past 5 years (81.4%), report a household income of $20 000 to $60 000 a year (48.8%), and born in the United States (83.7%). Participants reported that there was a DC within 30 minutes of their address (81.4%), their DC always explained things to them in an easy-to-understand manner (81.8%), their DC always showed respect for what they had to say (88.6%), and their DC always cared about them as a person (86.4%). Conclusions In the sample surveyed, non-Hispanic black patients tended to be female, be older, be college educated, be employed, and have a positive viewpoint on their interactions with their DC.

    This paper describes a concept for measuring the reproducible performance of mobile manipulators to be used for assembly or other similar tasks. An automatic guided vehicle with an onboard robot arm was programmed to repeatedly move to and stop at a novel, reconfigurable mobile manipulator artifact (RMMA), sense the RMMA, and detect targets on the RMMA. The manipulator moved a laser retroreflective sensor to detect small reflectors that can be reconfigured to measure various manipulator positions and orientations (poses). This paper describes calibration of a multi-camera, motion capture system using a 6 degree-of-freedom metrology bar and then using the camera system as a ground truth measurement device for validation of the reproducible mobile manipulator's experiments and test method. Static performance measurement of a mobile manipulator using the RMMA has proved useful for relatively high tolerance pose estimation and other metrics that support standard test method development for indexed and dynamic mobile manipulator applications.

    2012-01-01

    Objective Otitis media (OM) is one of the common conditions for doctor visits in the pediatric population. Spinal manipulation therapy (SMT) may be a potential conservative treatment of OM. The purpose of this study is to review the literature for OM in children, outlining the diagnosis of OM, SMT description, and adverse event notation. Methods Databases (PubMed, Cochrane Library, Cumulative Index to Nursing and Allied Health, Index to Chiropractic Literature, The Allied and Complementary Medicine, and Alt Health Watch) were queried and hand searches were performed to identify relevant articles. All potential studies were independently screened for inclusion by both authors. The inclusion criteria were as follows: written in the English language, addressed OM, involved human participants 6 years or younger, and addressed SMT. Studies were evaluated for overall quality using standardized checklists performed independently by both authors. Results Forty-nine articles were reviewed: 17 commentaries, 15 case reports, 5 case series, 8 reviews, and 4 clinical trials. Magnitude of effect was lower in higher-quality articles. No serious adverse events were found; minor transient adverse effects were noted in 1 case series article and 2 of the clinical trials. Conclusions From the studies found in this report, there was limited quality evidence for the use of SMT for children with OM. There are currently no evidence to support or refute using SMT for OM and no evidence to suggest that SMT produces serious adverse effects for children with OM. It is possible that some children with OM may benefit from SMT or SMT combined with other therapies. More rigorous studies are needed to provide evidence and a clearer picture for both practitioner and patients. PMID:23449823

    Social parasites may exploit their hosts by mimicking other organisms that the hosts normally benefit from investing in or responding to in some other way. Some parasites exaggerate key characters of the organisms they mimic, possibly in order to increase the response from the hosts. The huge gape and extreme begging intensity of the parasitic common cuckoo chick (Cuculus canorus) may be an example. In this paper, the evolutionary stability of manipulating hosts through exaggerated signals is analysed using game theory. Our model indicates that a parasite's signal intensity must be below a certain threshold in order to ensure acceptance and that this threshold depends directly on the rate of parasitism. The only evolutionarily stable strategy (ESS) combination is when hosts accept all signallers and parasites signal at their optimal signal intensity, which must be below the threshold. Supernormal manipulation by parasites is only evolutionarily stable under sufficiently low rates of parasitism. If the conditions for the ESS combination are not satisfied, rejector hosts can invade using signal intensity as a cue for identifying parasites. These qualitative predictions are discussed with respect to empirical evidence from parasitic mimicry systems that have been suggested to involve supernormal signalling, including evicting avian brood parasites and insect-mimicking Ophrys orchids.

    Ubiquitous smartphone ownership and reduced face-to-face teaching time may lead to students making greater use of mobile technologies in their learning. This is the first study to report on the prevalence of mobile gross anatomy software applications (apps) usage in pre-clinical chiropractic students and to ascertain if a relationship exists between preferred learning styles as determined by the validated VARK(©) questionnaire and use of mobile anatomy apps. The majority of the students who completed the VARK questionnaire were multimodal learners with kinesthetic and visual preferences. Sixty-seven percent (73/109) of students owned one or more mobile anatomy apps which were used by 57 students. Most of these students owned one to five apps and spent less than 30 minutes per week using them. Six of the top eight mobile anatomy apps owned and recommended by the students were developed by 3D4Medical. Visual learning preferences were not associated with time spent using mobile anatomy apps (OR = 0.40, 95% CI 0.12-1.40). Similarly, kinesthetic learning preferences (OR = 1.88, 95% CI 0.18-20.2), quadmodal preferences (OR = 0.71, 95% CI 0.06-9.25), or gender (OR = 1.51, 95% CI 0.48-4.81) did not affect the time students' spent using mobile anatomy apps. Learning preferences do not appear to influence students' time spent using mobile anatomy apps. Anat Sci Educ 9: 247-254. © 2015 American Association of Anatomists.

    Recently, task requirements have dictated that manipulator payload capacity increase to accommodate greater payloads, greater manipulator length, and larger environmental interaction forces. General tasks such as waste storage tank cleanup and facility dismantlement and decommissioning require manipulator life capacities in the range of hundreds of pounds rather than tens of pounds. To meet the increased payload capacities demanded by present-day tasks, manipulator designers have turned once again to hydraulics as a means of actuation. In order to successfully design, build, and deploy a new hydraulic manipulator (or subsystem), sophisticated modeling, analysis, and control experiments are usually needed. Oak Ridge National Laboratory (ORNL) has a history of projects that incorporate hydraulics technology, including mobile robots, teleoperated manipulators, and full-scale construction equipment. In addition, to support the development and deployment of new hydraulic manipulators, ORNL has outfitted a significant experimental laboratory and has developed the software capability for research into hydraulic manipulators, hydraulic actuators, hydraulic systems, modeling of hydraulic systems, and hydraulic controls. The purpose of this article is to describe the past hydraulic manipulator developments and current hydraulic manipulator research capabilities at ORNL. Included are example experimental results from ORNL`s flexible/prismatic test stand.

  13. Effectiveness of chiropractic and physiotherapy in the treatment of low back pain: a critical discussion of the British Randomized Clinical Trial.

    1991-06-01

    This article discusses the methodology of a recently published British randomized clinical trial comparing chiropractic and physiotherapy as treatments for low back pain. The authors base their main conclusions on a difference shown by the Oswestry pain questionnaire 2 yr after randomization, when data of only 26% of the patients were available. This might have led to an overestimation, because it appears that the difference in Oswestry scores is much larger for patients included early in the study. It may also be doubted whether the magnitude of the effect reported really indicates a clinically significant difference between the interventions. In addition to allocated intervention, the groups also differ in duration of treatment, number of sessions, level of experience of the therapist, and health care setting. The results are difficult to extrapolate, because only a small portion of the eligible patients participated, and chiropractic seems to be clearly superior only in the subgroup originally presenting to a chiropractic clinic. We conclude that it is premature to draw conclusions about the long-term effectiveness of chiropractic based on the results of this study alone.

    Introduction: A Canadian sports chiropractic research agenda has yet to be defined. The Delphi method can be utilized to achieve this purpose; however, the sample of experts who participate can influence the results. To better inform sample selection for future research agenda development, we set out to determine if differences in opinions about research priorities exist between chiropractors who have their sports specialty designation and those who do not. Methods: Fifteen sports clinical practice chiropractors who have their sports fellowship designation and fifteen without, were interviewed with a set of standardized questions about sports chiropractic research priorities. A centering resonance analysis and cluster analysis were conducted on the interview responses. Results: The two practitioner groups differed in their opinions about the type of research that they would like to see conducted, the research that would impact their clinical practice the most, and where they believed research was lacking. However, both groups were similar in their opinions about research collaborations. Conclusion: Sports clinical practice chiropractors, with their sports specialty designation and those without, differed in their opinions about sports chiropractic research priorities; however, they had similar opinions about research collaborations. These results suggest that it may be important to sample from both practitioner groups in future studies aimed at developing research agendas for chiropractic research in sport. PMID:28065995

    Introduction: It is important to create a body of evidence surrounding the reliability of certain diagnostic criteria. While the reliability of the Cobb measurement is well established with various licensed health care professionals, this study aims to determine the inter- and intra-observer reliability of the Cobb Measurement among chiropractic interns. Methods: Fourteen chiropractic interns analyzed 10 pre-selected digital spinal radiographs on a Picture Archiving and Communication System (PACS) in two separate rounds of observation. The participants indicated their choice of end vertebra and Cobb Measurement in each round of observation. Agreement on vertebral levels selected was estimated using percentage agreement. Intra-observer reliability was estimated using the Pearson r correlation coefficient, and inter-observer correlation was estimated using the Inter-Class Coefficient (ICC). Results: The range of percentage agreement on vertebral level selection was 0.36 – 0.79. The Pearson r correlation coefficient for round 1 and round 2 was 0.79. The ICC (3,1) was 0.79 (round 1), and 0.70 (round 2). Conclusion: Less than optimal agreement on end vertebrae selection was found between observers. Intra- and inter-observer reliability of the Cobb Measurement was ‘excellent’ (round 1) and ‘good’ (round 2). PMID:26500360

    Objective: This study explored how chiropractic interns applied evidenced-based concepts, the sources of evidence they used, and how useful they perceived these sources to be in clinical decision making. Methods: A questionnaire containing 13 items in a Likert 5-point scale was administered to 28 chiropractic interns to gather information on the evidence types they commonly accessed and their perceived usefulness of these sources in clinical decision making. The interns were in the 8th semester of the training program. Results: There was a 93% (n = 26) response rate. Clinical guidelines were rated as the most helpful resource in clinical decision making (81%), followed by lecture materials (77%), journals (54%), databases (50%), and textbooks (35%). Students recognized scientific evidence as the most important aspect in clinical decision making. They found their personal experience and the views of their clinician to be equally important and patient preference the least. Conclusion: Interns routinely employed high-quality levels of evidence in clinical decision making. They also considered their early, limited clinical experience as important as that of their clinical supervisor in decision making. This finding should be investigated further. PMID:27389528

    We describe an interactive visualization and modeling program for the creation of protein structures ''from scratch''. The input to our program is an amino acid sequence -decoded from a gene- and a sequence of predicted secondary structure types for each amino acid-provided by external structure prediction programs. Our program can be used in the set-up phase of a protein structure prediction process; the structures created with it serve as input for a subsequent global internal energy minimization, or another method of protein structure prediction. Our program supports basic visualization methods for protein structures, interactive manipulation based on inverse kinematics, and visualization guides to aid a user in creating ''good'' initial structures.

    An ion manipulation method and device is disclosed. The device includes a pair of substantially parallel surfaces. An array of inner electrodes is contained within, and extends substantially along the length of, each parallel surface. The device includes a first outer array of electrodes and a second outer array of electrodes. Each outer array of electrodes is positioned on either side of the inner electrodes, and is contained within and extends substantially along the length of each parallel surface. A DC voltage is applied to the first and second outer array of electrodes. A RF voltage, with a superimposed electric field, is applied to the inner electrodes by applying the DC voltages to each electrode. Ions either move between the parallel surfaces within an ion confinement area or along paths in the direction of the electric field, or can be trapped in the ion confinement area.

    1994-02-01

    Terrestrial manipulators with more DOF than the dimension of the workspace and space manipulators with as many manipulator DOF as the dimension of the workspace are both redundant systems. An interesting problem of such redundant systems has been the repeatability problem due to the presence of nonholonomic constraints. We show, contrary to the existing belief, that integrability of the nonholonomic constraints is not a necessary condition for the repeatability of the configuration variables. There exist certain trajectories in the independent configuration variable space that are like 'holonomic loops' along which the redundant manipulators exhibit repeatable motion. We present a simple method based on optimization techniques for designing repeatable trajectories for free-flying space manipulators and terrestrial manipulators under pseudoinverse control.

    Objective The purpose of this pilot study was to collect preliminary information for a study to determine the immediate effects of a single unilateral chiropractic manipulation to the lower cervical spine on handgrip strength and free-throw accuracy in asymptomatic male recreational basketball players. Methods For this study, 24 asymptomatic male recreational right-handed basketball players (age = 26.3 ± 9.2 years, height = 1.81 ± 0.07 m, body mass = 82.6 ± 10.4 kg [mean ± SD]) underwent baseline dominant handgrip isometric strength and free-throw accuracy testing in an indoor basketball court. They were then equally randomized to receive either (1) diversified left lower cervical spine chiropractic manipulative therapy (CMT) at C5/C6 or (2) placebo CMT at C5/C6 using an Activator adjusting instrument on zero force setting. Participants then underwent posttesting of isometric handgrip strength and free-throw accuracy. A paired-samples t test was used to make within-group pre to post comparisons and between-group pre to post comparisons. Results No statistically significant difference was shown between either of the 2 basketball performance variables measured in either group. Isometric handgrip strength marginally improved by 0.7 kg (mean) in the CMT group (P = .710). Free-throw accuracy increased by 13.2% in the CMT group (P = .058). The placebo CMT group performed the same or more poorly during their second test session. Conclusions The results of this preliminary study showed that a single lower cervical spine manipulation did not significantly impact basketball performance for this group of healthy asymptomatic participants. A slight increase in free-throw percentage was seen, which deserves further investigation. This pilot study demonstrates that a larger study to evaluate if CMT affects handgrip strength and free-throw accuracy is feasible. PMID:24396315

    The establishment of permanent low earth orbit occupation on the Space Station Freedom will present new opportunities for the introduction of productive flexible automation systems into the microgravity environment of space. The need for robust and reliable robotic systems to support experimental activities normally intended by astronauts will assume great importance. Many experimental modules on the space station are expected to require robotic systems for ongoing experimental operations. When implementing these systems, care must be taken not to introduce deleterious effects on the experiments or on the space station itself. It is important to minimize the acceleration effects on the experimental items being handled while also minimizing manipulator base reaction effects on adjacent experiments and on the space station structure. NASA Lewis Research Center has been performing research on these manipulator applications, focusing on improving the basic manipulator hardware, as well as developing improved manipulator control algorithms. By utilizing the modular manipulator concepts developed during the Laboratory Telerobotic Manipulator program, Oak Ridge National Laboratory has developed an experimental testbed system called the Microgravity Manipulator, incorporating two pitch-yaw modular positioners to provide a 4 dof experimental manipulator arm. A key feature in the design for microgravity manipulation research was the use of traction drives for torque transmission in the modular pitch-yaw differentials.

    ProteinShop Gives Researchers a Hands-On Tool for Manipulating, Visualizing Protein Structures. The Human Genome Project and other biological research efforts are creating an avalanche of new data about the chemical makeup and genetic codes of living organisms. But in order to make sense of this raw data, researchers need software tools which let them explore and model data in a more intuitive fashion. With this in mind, researchers at Lawrence Berkeley National Laboratory and the University of California, Davis, have developed ProteinShop, a visualization and modeling program which allows researchers to manipulate protein structures with pinpoint control, guided in large part by their own biological and experimental instincts. Biologists have spent the last half century trying to unravel the ''protein folding problem,'' which refers to the way chains of amino acids physically fold themselves into three-dimensional proteins. This final shape, which resembles a crumpled ribbon or piece of origami, is what determines how the protein functions and translates genetic information. Understanding and modeling this geometrically complex formation is no easy matter. ProteinShop takes a given sequence of amino acids and uses visualization guides to help generate predictions about the secondary structures, identifying alpha helices and flat beta strands, and the coil regions that bind them. Once secondary structures are in place, researchers can twist and turn these pre-configurations until they come up with a number of possible tertiary structure conformations. In turn, these are fed into a computationally intensive optimization procedure that tries to find the final, three-dimensional protein structure. Most importantly, ProteinShop allows users to add human knowledge and intuition to the protein structure prediction process, thus bypassing bad configurations that would otherwise be fruitless for optimization. This saves compute cycles and accelerates the entire process, so

  13. Acupuncture and chiropractic care for chronic pain in an integrated health plan: a mixed methods study

    PubMed Central

    2011-01-01

    Background Substantial recent research examines the efficacy of many types of complementary and alternative (CAM) therapies. However, outcomes associated with the "real-world" use of CAM has been largely overlooked, despite calls for CAM therapies to be studied in the manner in which they are practiced. Americans seek CAM treatments far more often for chronic musculoskeletal pain (CMP) than for any other condition. Among CAM treatments for CMP, acupuncture and chiropractic (A/C) care are among those with the highest acceptance by physician groups and the best evidence to support their use. Further, recent alarming increases in delivery of opioid treatment and surgical interventions for chronic pain--despite their high costs, potential adverse effects, and modest efficacy--suggests the need to evaluate real world outcomes associated with promising non-pharmacological/non-surgical CAM treatments for CMP, which are often well accepted by patients and increasingly used in the community. Methods/Design This multi-phase, mixed methods study will: (1) conduct a retrospective study using information from electronic medical records (EMRs) of a large HMO to identify unique clusters of patients with CMP (e.g., those with differing demographics, histories of pain condition, use of allopathic and CAM health services, and comorbidity profiles) that may be associated with different propensities for A/C utilization and/or differential outcomes associated with such care; (2) use qualitative interviews to explore allopathic providers' recommendations for A/C and patients' decisions to pursue and retain CAM care; and (3) prospectively evaluate health services/costs and broader clinical and functional outcomes associated with the receipt of A/C relative to carefully matched comparison participants receiving traditional CMP services. Sensitivity analyses will compare methods relying solely on EMR-derived data versus analyses supplementing EMR data with conventionally collected patient

    We investigate the interplay between the thermodynamic properties and spin-dependent transport in a mesoscopic device based on a magnetic multilayer (F/f/F), in which two strongly ferromagnetic layers (F) are exchange-coupled through a weakly ferromagnetic spacer (f) with the Curie temperature in the vicinity of room temperature. We show theoretically that the Joule heating produced by the spin-dependent current allows a spin-thermoelectronic control of the ferromagnetic-to-paramagnetic (f/N) transition in the spacer and, thereby, of the relative orientation of the outer F-layers in the device (spin-thermoelectric manipulation of nanomagnets). Supporting experimental evidence of such thermally-controlled switching from parallel to antiparallel magnetization orientations in F/f(N)/F sandwiches is presented. Furthermore, we show theoretically that local Joule heating due to a high concentration of current in a magnetic point contact or a nanopillar can be used to reversibly drive the weakly ferromagnetic spacer through its Curie point and thereby exchange couple and decouple the two strongly ferromagnetic F-layers. For the devices designed to have an antiparallel ground state above the Curie point of the spacer, the associated spin-thermionic parallel to antiparallel switching causes magnetoresistance oscillations whose frequency can be controlled by proper biasing from essentially dc to GHz. We discuss in detail an experimental realization of a device that can operate as a thermomagnetoresistive switch or oscillator.

    The purpose of this study was to investigate the contribution of stereopsis to the processing of observed manipulative actions. To this end, we first combined the factors “stimulus type” (action, static control, and dynamic control), “stereopsis” (present, absent) and “viewpoint” (frontal, lateral) into a single design. Four sites in premotor, retro-insular (2) and parietal cortex operated specifically when actions were viewed stereoscopically and frontally. A second experiment clarified that the stereo-action-specific regions were driven by actions moving out of the frontoparallel plane, an effect amplified by frontal viewing in premotor cortex. Analysis of single voxels and their discriminatory power showed that the representation of action in the stereo-action-specific areas was more accurate when stereopsis was active. Further analyses showed that the 4 stereo-action-specific sites form a closed network converging onto the premotor node, which connects to parietal and occipitotemporal regions outside the network. Several of the specific sites are known to process vestibular signals, suggesting that the network combines observed actions in peripersonal space with gravitational signals. These findings have wider implications for the function of premotor cortex and the role of stereopsis in human behavior. PMID:27252350

  16. Genetic Manipulations in Dermatophytes.

    Dermatophytes are a group of closely related fungi that nourish on keratinized materials for their survival. They infect stratum corneum, nails, and hair of human and animals, accounting the largest portion of fungi causing superficial mycoses. Huge populations are suffering from dermatophytoses, though the biology of these fungi is largely unknown yet. Reasons are partially attributed to the poor amenability of dermatophytes to genetic manipulation. However, advancements in this field over the last decade made it possible to conduct genetic studies to satisfying extents. These included genetic transformation methods, indispensable molecular tools, i.e., dominant selectable markers, inducible promoter, and marker recycling system, along with improving homologous recombination frequency and gene silencing. Furthermore, annotated genome sequences of several dermatophytic species have recently been available, ensuring an optimal recruitment of the molecular tools to expand our knowledge on these fungi. In conclusion, the establishment of basic molecular tools and the availability of genomic data will open a new era that might change our understanding on the biology and pathogenicity of this fungal group.

    Objectives High velocity low amplitude spinal manipulation (HVLA-SM), as performed by manual therapists (eg, doctors of chiropractic and osteopathy) results in mechanical hypoalgesia in clinical settings. This hypoalgesic effect has previously been attributed to alterations in peripheral and/or central pain processing. The objective of this study was to determine whether thrust magnitude of a simulated HVLA-SM alters mechanical trunk response thresholds in wide dynamic range (WDR) and/or nociceptive specific (NS) lateral thalamic neurons. Methods Extracellular recordings were carried out in the thalamus of 15 anesthetized Wistar rats. Lateral thalamic neurons having receptive fields which included the lumbar dorsal-lateral trunk were characterized as either WDR (n=22) or NS (n=25). Response thresholds to electronic von Frey (rigid tip) mechanical trunk stimuli were determined in three directions (dorsal-ventral, 45°caudalward, and 45°cranialward) prior to and immediately following the dorsal-ventral delivery of a 100ms HVLA-SM at three thrust magnitudes (control, 55%, 85% body weight; (BW)). Results There was a significant difference in mechanical threshold between 85% BW manipulation and control thrust magnitudes in the dorsal-ventral direction in NS neurons (p=.01). No changes were found in WDR neurons at either HVLA-SM thrust magnitude. Conclusions This study is the first to investigate the effect of HVLA-SM thrust magnitude on WDR and NS lateral thalamic mechanical response threshold. Our data suggest that at the single lateral thalamic neuron level, there may be a minimal spinal manipulative thrust magnitude required to elicit an increase in trunk mechanical response thresholds.

  20. Direct Manipulation in Virtual Reality

    2003-01-01

    Virtual Reality interfaces offer several advantages for scientific visualization such as the ability to perceive three-dimensional data structures in a natural way. The focus of this chapter is direct manipulation, the ability for a user in virtual reality to control objects in the virtual environment in a direct and natural way, much as objects are manipulated in the real world. Direct manipulation provides many advantages for the exploration of complex, multi-dimensional data sets, by allowing the investigator the ability to intuitively explore the data environment. Because direct manipulation is essentially a control interface, it is better suited for the exploration and analysis of a data set than for the publishing or communication of features found in that data set. Thus direct manipulation is most relevant to the analysis of complex data that fills a volume of three-dimensional space, such as a fluid flow data set. Direct manipulation allows the intuitive exploration of that data, which facilitates the discovery of data features that would be difficult to find using more conventional visualization methods. Using a direct manipulation interface in virtual reality, an investigator can, for example, move a data probe about in space, watching the results and getting a sense of how the data varies within its spatial volume.

    Abstract This article presents the development of an autonomous motion planning algorithm for a soft planar grasping manipulator capable of grasp-and-place operations by encapsulation with uncertainty in the position and shape of the object. The end effector of the soft manipulator is fabricated in one piece without weakening seams using lost-wax casting instead of the commonly used multilayer lamination process. The soft manipulation system can grasp randomly positioned objects within its reachable envelope and move them to a desired location without human intervention. The autonomous planning system leverages the compliance and continuum bending of the soft grasping manipulator to achieve repeatable grasps in the presence of uncertainty. A suite of experiments is presented that demonstrates the system's capabilities. PMID:27625916

    This study assessed the reliability and potential value of a specific Centre of Pressure Locator (COPL) for the initial diagnosis of spinal mal-alignments and for the measurement of change in weight distribution resulting from clinical intervention. Basic validation of the equipment with standard weights showed it to be very precise, reliable and accurate at noting changes in the position of the centre of pressure. Control subjects were used to develop interim norms for COP position and sway. R-L COP position among both controls and patients was found to be too variable to be a useful tool for diagnosis or for the measurement of the effects of intervention. However, the equipment shows promise for the measurement of A-P and R-L postural sway; potentially important variables to consider within chiropractic practice.

    The purpose of this study was to explore the role of chiropractic in the treatment of dizziness or balance disorders through an analysis of data from the 2008 National Health Interview Survey. Odds ratios and 95% confidence intervals (CIs) were used to assess the likelihood that respondents with dizziness or balance problems perceived that they were helped by specified practitioners. Eleven percent of respondents reported having had a balance or dizziness problem; more than 35% were aged 65 years and older. The odds ratio for perceiving being helped by a chiropractor was 4.36 (95% CI, 1.17-16.31) for respondents aged 65 years or older; 9.5 (95% CI, 7.92-11.40) for respondents reporting head or neck trauma; and 13.78 (95% CI, 5.59-33.99) for those reporting neurological or muscular conditions as the cause of their balance or dizziness.

    Comments on the application to rigid link manipulators of geometric control theory, resolved acceleration control, operational space control, and nonlinear decoupling theory are given, and the essential unity of these techniques for externally linearizing and decoupling end effector dynamics is discussed. Exploiting the fact that the mass matrix of a rigid link manipulator is positive definite, a consequence of rigid link manipulators belonging to the class of natural physical systems, it is shown that a necessary and sufficient condition for a locally externally linearizing and output decoupling feedback law to exist is that the end effector Jacobian matrix be nonsingular. Furthermore, this linearizing feedback is easy to produce.

    Survey of the present technological development status of machine intelligence for autonomous manipulation in the U.S., Japan, USSR, and England. The extent of task-performance autonomy is examined that machine intelligence gives the manipulator by eliminating the need for a human operator to close continuously the control loop, or to rewrite control programs for each different task. Surveyed research projects show that the development of some advanced automation systems for manipulator control are within the state of the art. Yet, many more realistic breadboard systems and experimental work are needed before further progress can be made in the design of advanced automation systems for manipulator control suitable for new major practical applications. Specific research areas of promise are pointed out.

    Abstract Objective There has been a steady growth of chiropractic treatment using spinal manipulative therapy (SMT) that aims to increase the performance of athletes in various sports. This study evaluates the effect of SMT by chiropractors on the performance of golf players. Methods Golfers of 2 golf clubs in São Paulo, Brazil, participated in this study. They were randomized to 1 of 2 groups: Group I received a stretch program, and group II received a stretch program in addition to SMT. Participants in both groups performed the same standardized stretching program. Spinal manipulative therapy to dysfunctional spinal segments was performed on group II only. All golfers performed 3 full-swing maneuvers. Ball range was considered as the average distance for the 3 shots. Treatment was performed after the initial measurement, and the same maneuvers were performed afterward. Each participant repeated these procedures for a 4-week period. Student t test, Mann-Whitney nonparametric test, and 1-way analysis of variance for repeated measures with significance level of 5% were used to analyze the study. Results Forty-three golfers completed the protocol. Twenty participants were allocated to group I and 23 to group II. Average age, handicap, and initial swing were comparable. No improvement of full-swing performance was observed during the 4 sessions on group I (stretch only). An improvement was observed at the fourth session of group II (P = .005); when comparing the posttreatment, group II had statistical significance at all phases (P = .003). Conclusions Chiropractic SMT in association with muscle stretching may be associated with an improvement of full-swing performance when compared with muscle stretching alone. PMID:19948307

  10. Manipulation: description, identification and ambiguity.

    PubMed

    Bowers, L

    2003-06-01

    The word manipulation is frequently applied to some of the difficult-to-manage behaviours of the personality-disordered patient. However, the term is rarely defined, and a review of both the clinical and research literature shows that little has been written about its definition and identification, let alone its clinical management in both in- and outpatient settings. Recent empirical work conducted with nurses in forensic settings has demonstrated the range of behaviours that professionals refer to as 'manipulative', thus clarifying the use of the term and allowing the provision of a more precise definition. The scope of manipulation in everyday life, management practice and politics is perhaps relatively small, although manipulation can occur in all areas of human activity. Social behaviour is doubly ambiguous with respect to judgements of manipulation, as such judgements involve a moral evaluation combined with the identification of deception on the basis of little or partial evidence. The implications of this social ambiguity for clinical psychiatric practice are that professionals need to guard themselves from two polar faults: seeing manipulation everywhere; or being blind to its presence. In order to achieve a cautious moderation, staff need to hold both alternatives in mind at all times.

    Objective The aim of this study was to explore the relationship between chiropractic students' coping styles and levels of resilience with their physical injuries, perceived levels of stress, and well-being. Methods A questionnaire was distributed to the entire student body of the chiropractic program at Murdoch University, and gathered demographic variables and responses to the Connor-Davidson Resilience Scale, Perceived Levels of Stress Scale, Everyday Feelings Questionnaire, and Coping Inventory for Stressful Situations. Linear regression analysis was used to calculate for significant relationships. Results Of 244 students, 194 (81%) completed the surveys. Being female and not having recovered from an injury within 12 months was significantly associated with lower levels of well-being and higher levels of stress. Being female, possessing an increased use of an emotional-based coping style, and having lower levels of well-being were associated with higher levels of stress (R2 = 0.65, F(6,164) = 50.47, p < .001). Lower levels of well-being were associated with being female, higher perceived levels of stress, lower levels of resilience, and an increased use emotional coping styles (R2 = 0.64, F[6,164] = 49.5, p < .001). Conclusion It is possible to identify chiropractic students at the university who are at risk of experiencing low levels of well-being and high levels of stress. These students may benefit from interventions aimed at enhancing their coping style choices and increasing their resilience levels. Future studies are recommended to see if these findings are consistent across chiropractic programs nationally and internationally. PMID:27459674

    Introduction: Chronic lower back pain (CLBP) is problematic in older veterans. Spinal manipulative therapy (SMT) is commonly utilized for CLBP in older adults, yet there are few randomized placebo-controlled trials evaluating SMT. Methods: The purpose of the study was to compare the effectiveness of SMT to a sham intervention on pain (Visual Analogue Scale, SF-36 pain subscale), disability (Oswestry Disability Index), and physical function (SF-36 subscale, Timed Up and Go) by performing a randomized placebo-controlled trial at 2 Veteran Affairs Clinics. Results: Older veterans (≥ 65 years of age) who were naive to chiropractic were recruited. A total of 136 were included in the study with 69 being randomly assigned to SMT and 67 to sham intervention. Patients were treated 2 times per week for 4 weeks assessing outcomes at baseline, 5, and 12 weeks postbaseline. Both groups demonstrated significant decrease in pain and disability at 5 and 12 weeks. At 12 weeks, there was no significant difference in pain and a statistically significant decline in disability scores in the SMT group when compared to the sham intervention group. There were no significant differences in adverse events between the groups. Conclusions: The SMT did not result in greater improvement in pain when compared to our sham intervention; however, SMT did demonstrate a slightly greater improvement in disability at 12 weeks. The fact that patients in both groups showed improvements suggests the presence of a nonspecific therapeutic effect. PMID:26246937

    Objective: The purpose of this study was to determine if diagnostic and therapeutic procedures for the cervical and cranial spine taught to students during the undergraduate program at Canadian Memorial Chiropractic College are required to be used during their internship by their supervising clinicians and, if so, to what extent these procedures are used. Methods: Course manuals and course syllabi from the Applied Chiropractic and Clinical Diagnosis faculty of the undergraduate chiropractic program for the academic year 2009–2010 were consulted and a list of all diagnostic and therapeutic procedures for the cranial and cervical spine was compiled. This survey asked clinicians to indicate if they themselves used or if they required the students they were supervising to use each procedure listed and, if so, to what extent each procedure was used. Demographic information of each clinician was also obtained. Results: In general, most diagnostic procedures of the head and neck were seldom used, with the exception of postural observation and palpation. By contrast, most cervical orthopaedic tests were often used, with the exception of tests for vertigo. Most therapeutic procedures were used frequently with the exception of prone cervical and “muscle” adjustments. Conclusion: There was a low degree of vertical integration for cranial procedures as compared to a much higher degree of vertical integration for cervical procedures between the undergraduate and clinical internship programs taught. Vertical integration is an important element of curricular planning and these results may be helpful to aid educators to more appropriately allocate classroom instruction PMID:22778531

    Objective The purposes of this study were to estimate the 1-month point prevalence of bowel and bladder symptoms (BBS) among adult chiropractic patients and to evaluate associations between these symptoms and low back pain (LBP). Methods Patients 18 years or older presenting to a chiropractic college academic health clinic between March 25 and April 25, 2013, were asked to complete a symptom screening questionnaire. Descriptive statistics, binary logistic regression, Fisher exact test, and P values were calculated from the sample. Results The sample included 140 of 1300 patients who visited the clinic during the survey period (11%). Mean age was 47.5 (range 18-79) years. LBP was the primary chief complaint in 42%. The 1-month point prevalence of any bladder symptoms was 75%, while the rate for bowel symptoms was 62%; 55% reported both BBS. Binary logistic regression analyses showed no statistically significant association between a chief complaint of LBP and combined BBS (OR = 1.67, P = .164). Conclusion The prevalence of bowel and bladder symptoms in chiropractic patients was high. There was no statistically significant association between these symptoms and LBP in this group of patients seeking care for LBP. PMID:25225466

    The invention is a method of using computer vision to control systems consisting of a combination of holonomic and nonholonomic degrees of freedom such as a wheeled rover equipped with a robotic arm, a forklift, and earth-moving equipment such as a backhoe or a front-loader. Using vision sensors mounted on the mobile system and the manipulator, the system establishes a relationship between the internal joint configuration of the holonomic degrees of freedom of the manipulator and the appearance of features on the manipulator in the reference frames of the vision sensors. Then, the system, perhaps with the assistance of an operator, identifies the locations of the target object in the reference frames of the vision sensors. Using this target information, along with the relationship described above, the system determines a suitable trajectory for the nonholonomic degrees of freedom of the base to follow towards the target object. The system also determines a suitable pose or series of poses for the holonomic degrees of freedom of the manipulator. With additional visual samples, the system automatically updates the trajectory and final pose of the manipulator so as to allow for greater precision in the overall final position of the system.

    2016-04-01

    Unraveling the complex network of neural circuits that form the nervous system demands tools that can manipulate specific circuits. The recent evolution of genetic tools to target neural circuits allows an unprecedented precision in elucidating their function. Here we describe two general approaches for achieving circuit specificity. The first uses the genetic identity of a cell, such as a transcription factor unique to a circuit, to drive expression of a molecule that can manipulate cell function. The second uses the spatial connectivity of a circuit to achieve specificity: one genetic element is introduced at the origin of a circuit and the other at its termination. When the two genetic elements combine within a neuron, they can alter its function. These two general approaches can be combined to allow manipulation of neurons with a specific genetic identity by introducing a regulatory gene into the origin or termination of the circuit. We consider the advantages and disadvantages of both these general approaches with regard to specificity and efficacy of the manipulations. We also review the genetic techniques that allow gain- and loss-of-function within specific neural circuits. These approaches introduce light-sensitive channels (optogenetic) or drug sensitive channels (chemogenetic) into neurons that form specific circuits. We compare these tools with others developed for circuit-specific manipulation and describe the advantages of each. Finally, we discuss how these tools might be applied for identification of the neural circuits that mediate behavior and for repair of neural connections.

  19. Collaborative Care for Older Adults with low back pain by family medicine physicians and doctors of chiropractic (COCOA): study protocol for a randomized controlled trial

    PubMed Central

    2013-01-01

    Background Low back pain is a prevalent and debilitating condition that affects the health and quality of life of older adults. Older people often consult primary care physicians about back pain, with many also receiving concurrent care from complementary and alternative medicine providers, most commonly doctors of chiropractic. However, a collaborative model of treatment coordination between these two provider groups has yet to be tested. The primary aim of the Collaborative Care for Older Adults Clinical Trial is to develop and evaluate the clinical effectiveness and feasibility of a patient-centered, collaborative care model with family medicine physicians and doctors of chiropractic for the treatment of low back pain in older adults. Methods/design This pragmatic, pilot randomized controlled trial will enroll 120 participants, age 65 years or older with subacute or chronic low back pain lasting at least one month, from a community-based sample in the Quad-Cities, Iowa/Illinois, USA. Eligible participants are allocated in a 1:1:1 ratio to receive 12 weeks of medical care, concurrent medical and chiropractic care, or collaborative medical and chiropractic care. Primary outcomes are self-rated back pain and disability. Secondary outcomes include general and functional health status, symptom bothersomeness, expectations for treatment effectiveness and improvement, fear avoidance behaviors, depression, anxiety, satisfaction, medication use and health care utilization. Treatment safety and adverse events also are monitored. Participant-rated outcome measures are collected via self-reported questionnaires and computer-assisted telephone interviews at baseline, and at 4, 8, 12, 24, 36 and 52 weeks post-randomization. Provider-rated expectations for treatment effectiveness and participant improvement also are evaluated. Process outcomes are assessed through qualitative interviews with study participants and research clinicians, chart audits of progress notes and content

  2. Employee involvement: motivation or manipulation?

    PubMed

    McConnell, C R

    1998-03-01

    Employee involvement is subject to a great deal of verbal tribute; there is hardly a manager at work today who will not praise the value of employee input. However, many employee involvement efforts leave employees feeling more manipulated than motivated. This occurs because supervisors and managers, while expecting employees to change the way they work, are themselves either unwilling to change or remain unconscious of the need to change. The result is that, although employee input is regularly solicited in a number of forms, it is often discounted, ignored, or altered to fit the manager's preconceptions. Often the employee is left feeling manipulated. Since the opportunity for involvement can be a strong motivator, it becomes the manager's task to learn how to provide involvement opportunity in manipulative fashion. This can be accomplished by providing involvement opportunity accompanied by clear outcome expectations and allowing employees the freedom to pursue those outcomes in their own way.

    2013-01-01

    Recent developments in the field of metamaterials have revealed unparalleled opportunities for “engineering” space for light propagation; opening a new paradigm in spin- and quantum-related phenomena in optical physics. Here we show that unique optical properties of metamaterials (MMs) open unlimited prospects to “engineer” light itself. We propose and demonstrate for the first time a novel way of complex light manipulation in few-mode optical fibers using optical MMs. Most importantly, these studies highlight how unique properties of MMs, namely the ability to manipulate both electric and magnetic field components of electromagnetic (EM) waves, open new degrees of freedom in engineering complex polarization states of light at will, while preserving its orbital angular momentum (OAM) state. These results lay the first steps in manipulating complex light in optical fibers, likely providing new opportunities for high capacity communication systems, quantum information, and on-chip signal processing.

    2006-01-01

    Background Given the relative lack of treatment options for mild to moderate scoliosis, when the Cobb angle measurements fall below the 25–30° range, conservative manual therapies for scoliosis treatment have been increasingly investigated in recent years. In this case series, we present 3 specific cases of scoliosis. Case presentation Patient presentation, examination, intervention and outcomes are detailed for each case. The types of scoliosis presented here are left thoracic, idiopathic scoliosis after Harrington rod instrumentation, and a left thoracic scoliosis secondary to Scheuermann's Kyphosis. Each case carries its own clinical significance, in relation to clinical presentation. The first patient presented for chiropractic treatment with a 35° thoracic dextroscoliosis 18 years following Harrington Rod instrumentation and fusion. The second patient presented with a 22° thoracic levoscoliosis and concomitant Scheuermann's Disease. Finally, the third case summarizes the treatment of a patient with a primary 37° idiopathic thoracic levoscoliosis. Each patient was treated with a novel active rehabilitation program for varying lengths of time, including spinal manipulation and a patented external head and body weighting system. Following a course of treatment, consisting of clinic and home care treatments, post-treatment radiographs and examinations were conducted. Improvement in symptoms and daily function was obtained in all 3 cases. Concerning Cobb angle measurements, there was an apparent reduction in Cobb angle of 13°, 8°, and 16° over a maximum of 12 weeks of treatment. Conclusion Although mild to moderate reductions in Cobb angle measurements were achieved in these cases, these improvements may not be related to the symptomatic and functional improvements. The lack of a control also includes the possibility of a placebo effect. However, this study adds to the growing body of literature investigating methods by which mild to moderate cases of

    Modular manipulator designs have long been considered for use as research tools, and as the basis for easily modified industrial manipulators. In these manipulators the links and joints are discrete and modular components that can be assembled into a desired manipulator configuration. As hardware advances have made actual modular manipulators practical, various capabilities of such manipulators have gained interest. Particularly desirable is the ability to rapidly reconfigure such a manipulator, in order to custom tailor it to specific tasks. The reconfiguration greatly enhances the capability of a given amount of manipulator hardware. The development of a prototype modular manipulator is discussed as well as the implementation of a configuration independent manipulator kinematics algorithm used for path planning in the prototype.

  6. Understanding pharmaceutical research manipulation in the context of accounting manipulation.

    2013-01-01

    The problem of the manipulation of data that arises when there is both opportunity and incentive to mislead is better accepted and studied - though by no means solved - in financial accounting than in medicine. This article analyzes pharmaceutical company manipulation of medical research as part of a broader problem of corporate manipulation of data in the creation of accounting profits. The article explores how our understanding of accounting fraud and misinformation helps us understand the risk of similar information manipulation in the medical sciences. This understanding provides a framework for considering how best to improve the quality of medical research and analysis in light of the current system of medical information production. I offer three possible responses: (1) use of the Dodd-Frank whistleblower provisions to encourage reporting of medical research fraud; (2) a two-step academic journal review process for clinical trials; and (3) publicly subsidized trial-failure insurance. These would improve the release of negative information about drugs, thereby increasing the reliability of positive information.

    This work addresses several challenges of cooperative transportThis work addresses several challenges of cooperative transport and precision manipulation. Precision manipulation requires a rigid grasp, which places a hard constraint on the relative rover formation that must be accommodated, even though the rovers cannot directly observe their relative poses. Additionally, rovers must jointly select appropriate actions based on all available sensor information. Lastly, rovers cannot act on independent sensor information, but must fuse information to move jointly; the methods for fusing information must be determined.

    2017-01-01

    The coherent manipulation of spin and pseudospin underlies existing and emerging quantum technologies, including quantum communication and quantum computation. Valley polarization, associated with the occupancy of degenerate, but quantum mechanically distinct valleys in momentum space, closely resembles spin polarization and has been proposed as a pseudospin carrier for the future quantum electronics. Valley exciton polarization has been created in the transition metal dichalcogenide monolayers using excitation by circularly polarized light and has been detected both optically and electrically. In addition, the existence of coherence in the valley pseudospin has been identified experimentally. The manipulation of such valley coherence has, however, remained out of reach. Here we demonstrate all-optical control of the valley coherence by means of the pseudomagnetic field associated with the optical Stark effect. Using below-bandgap circularly polarized light, we rotate the valley exciton pseudospin in monolayer WSe2 on the femtosecond timescale. Both the direction and speed of the rotation can be manipulated optically by tuning the dynamic phase of excitons in opposite valleys. This study unveils the possibility of generation, manipulation, and detection of the valley pseudospin by coupling to photons.

    Although psychology is the science of mental life and behavior, it has paid little attention to the means by which mental life is translated into behavior. One domain where links between cognition and action have been explored is the manipulation of objects. This article reviews psychological research on this topic, with special emphasis on the tendency to grasp objects differently depending on what one plans to do with the objects. Such differential grasping has been demonstrated in a wide range of object manipulation tasks, including grasping an object in a way that reveals anticipation of the object's future orientation, height, and required placement precision. Differential grasping has also been demonstrated in a wide range of behaviors, including one-hand grasps, two-hand grasps, walking, and transferring objects from place to place as well as from person to person. The populations in whom the tendency has been shown are also diverse, including nonhuman primates as well as human adults, children, and babies. Meanwhile, the tendency is compromised in a variety of clinical populations and in children of a surprisingly advanced age. Verbal working memory is compromised as well if words are memorized while object manipulation tasks are performed; the recency portion of the serial position curve is reduced in this circumstance. In general, the research reviewed here points to rich connections between cognition and action as revealed through the study of object manipulation. Other implications concern affordances, Donders' Law, and naturalistic observation and the teaching of psychology. PMID:22448912

    2001-07-31

    ARM Automation, Inc. is developing a framework of modular actuators that can address the DOE's wide range of robotics needs. The objective of this effort is to demonstrate the effectiveness of this technology by constructing a manipulator from these actuators within a glovebox for Automated Plutonium Processing (APP). At the end of the project, the system of actuators was used to construct several different manipulator configurations, which accommodate common glovebox tasks such as repackaging. The modular nature and quickconnects of this system simplify installation into ''hot'' boxes and any potential modifications or repair therein. This work focused on the development of self-contained robotic actuator modules including the embedded electronic controls for the purpose of building a manipulator system. Both of the actuators developed under this project contain the control electronics, sensors, motor, gear train, wiring, system communications and mechanical interfaces of a complete robotics servo device. Test actuators and accompanying DISC{trademark}s underwent validation testing at The University of Texas at Austin and ARM Automation, Inc. following final design and fabrication. The system also included custom links, an umbilical cord, an open architecture PC-based system controller, and operational software that permitted integration into a completely functional robotic manipulator system. The open architecture on which this system is based avoids proprietary interfaces and communication protocols which only serve to limit the capabilities and flexibility of automation equipment. The system was integrated and tested in the contractor's facility for intended performance and operations. The manipulator was tested using the full-scale equipment and process mock-ups. The project produced a practical and operational system including a quantitative evaluation of its performance and cost.

    Among the different strategies used by parasites to usurp the behaviour of their host, one of the most fascinating is bodyguard manipulation. While all classic examples of bodyguard manipulation involve insect parasitoids, induced protective behaviours have also evolved in other parasite-host systems, typically as specific dimensions of the total manipulation. For instance, parasites may manipulate the host to reduce host mortality during their development or to avoid predation by non-host predators. This type of host manipulation behaviour is rarely described, probably due to the fact that studies have mainly focused on predation enhancement rather than studying all the dimensions of the manipulation. Here, in addition to the classic cases of bodyguard manipulation, we also review these 'bodyguard dimensions' and propose extending the current definition of bodyguard manipulation to include the latter. We also discuss different evolutionary scenarios under which such manipulations could have evolved.

    Objective: This pilot study explored the attitudes, beliefs, and intentions of a group of chiropractic interns concerning health promotion, wellness, and preventive services before and after a series of brief educational interventions. Methods: Interns completed a survey before (n = 37) and after (n = 22) the interventions. The survey included 12 Likert scale questions about attitudes and intentions toward wellness and health promotion models. The interventions consisted of classroom lectures, clinical training, and online information pertaining to health promotion and wellness. Results: The interns initially favored wellness models, perceived a need for them, and felt partially prepared to administer them, with mean Likert scores 4 or greater on a 1 to 5 scale. Afterward, the average scores were higher and the interns reported some benefit from this short course of training. Conclusion: The initial survey demonstrated that interns had some understanding of wellness, health promotion, and preventive services, and favored utilization of these services. The follow-up survey suggested that a short educational intervention could have a positive impact on these attitudes and future utilization of wellness procedures in their practices. PMID:27314433

    Background: Practice based research networks (PBRNs) are increasingly used as a tool for evidence based practice. We developed and tested the feasibility of using software to enable online collection of patient data within a chiropractic PBRN to support clinical decision making and research in participating clinics. Purpose: To assess the feasibility of using online software to collect quality patient information. Methods: The study consisted of two phases: 1) Assessment of the quality of information provided, using a standardized form; and 2) Exploration of patients’ perspectives and experiences regarding online information provision through semi-structured interviews. Data analysis was descriptive. Results: Forty-five new patients were recruited. Thirty-six completed online forms, which were submitted by an appropriate person 100% of the time, with an error rate of less than 1%, and submitted in a timely manner 83% of the time. Twenty-one participants were interviewed. Overall, online forms were preferred given perceived security, ease of use, and enabling provision of more accurate information. Conclusions: Use of online software is feasible, provides high quality information, and is preferred by most participants. A pen-and-paper format should be available for patients with this preference and in case of technical difficulties. PMID:27069272

    PubMed

    Dishman, R W

    1988-04-01

    Intervertebral dysfunction refers to a biomechanical fault which is abnormal in both its dynamic and static components. A subluxation may be considered as being fixated and also slightly malpositioned in one or more axes of rotation. Subluxation may be considered as one component of a complex or syndrome of intervertebral dyskinesia, dysarthrosis or dysfunction. The biochemical and histological components explain some of the pain mechanisms, tissue changes and residual effects of acute and chronic intervertebral fixation and the need for repeated spinal manipulations and prolonged care. Interexaminer reliability studies indicate that a standard method of motion palpation is quite feasible and accurate. X-ray evidence of dyskinesia shows promise as a means of documenting subluxation fixations.

  2. Position control of robot manipulators manipulating a flexible payload

    SciTech Connect

    Sun, D.; Mills, J.K.; Liu, Y.

    1999-03-01

    Robotic manipulation of a flexible payload is a complex and challenging control problem. This paper demonstrates from both theoretical and experimental perspectives that through proper design of the control gains, the simple scheme of PD plus gravity compensation can control a flexible payload manipulated by multiple robots to a desired position/orientation while damping the vibrations of the payload at each contact. The suppression of the vibration at each contact is helpful to suppress all vibrations of the flexible body. If the payload has a large stiffness or small mass, the proposed scheme can regulate the deformations at the contacts to zero, and also, the offsets of all static deformations of the payload with reference to the original positions decay to zero. A clamped-free model is used to decompose the dynamics of the payload into two distinct dynamic subsystems. This allows them to treat these dynamic subsystems separately and prove that desired motion trajectories can be achieved with the proposed scheme. As an example, the experiment of manipulating a flexible sheet using two CRS A460 robots is further described.

    1987-01-01

    Simple methods for the design of adaptive force and position controllers for robot manipulators within the hybrid control architecuture is presented. The force controller is composed of an adaptive PID feedback controller, an auxiliary signal and a force feedforward term, and it achieves tracking of desired force setpoints in the constraint directions. The position controller consists of adaptive feedback and feedforward controllers and an auxiliary signal, and it accomplishes tracking of desired position trajectories in the free directions. The controllers are capable of compensating for dynamic cross-couplings that exist between the position and force control loops in the hybrid control architecture. The adaptive controllers do not require knowledge of the complex dynamic model or parameter values of the manipulator or the environment. The proposed control schemes are computationally fast and suitable for implementation in on-line control with high sampling rates.

  5. Nanoparticle manipulation by thermal gradient

    PubMed Central

    2012-01-01

    A method was proposed to manipulate nanoparticles through a thermal gradient. The motion of a fullerene molecule enclosed inside a (10, 10) carbon nanotube with a thermal gradient was studied by molecular dynamics simulations. We created a one-dimensional potential valley by imposing a symmetrical thermal gradient inside the nanotube. When the temperature gradient was large enough, the fullerene sank into the valley and became trapped. The escaping velocities of the fullerene were evaluated based on the relationship between thermal gradient and thermophoretic force. We then introduced a new way to manipulate the position of nanoparticles by translating the position of thermostats with desirable thermal gradients. Compared to nanomanipulation using a scanning tunneling microscope or an atomic force microscope, our method for nanomanipulation has a great advantage by not requiring a direct contact between the probe and the object.

    We investigate the integration of visual and tactile sensory input for dynamic manipulation. Our experimental data and computational modeling reveal that time-delays are as critical to task-optimal multisensory integration as sensorimotor noise. Our focus is a dynamic manipulation task “at the edge of instability.” Mathematical bifurcation theory predicts that this system will exhibit well-classified low-dimensional dynamics in this regime. The task was using the thumbpad to compress a slender spring prone to buckling as far as possible, just shy of slipping. As expected from bifurcation theory, principal components analysis gives a projection of the data onto a low dimensional subspace that captures 91-97% of its variance. In this subspace, we formulate a low-order model for the brain+hand+spring dynamics based on known mechanical and neurophysiological properties of the system. By systematically occluding vision and anesthetically blocking thumbpad sensation in 12 consenting subjects, we found that vision contributed to dynamic manipulation only when thumbpad sensation was absent. The reduced ability of the model system to compress the spring with absent sensory channels closely resembled the experimental results. Moreover, we found that the model reproduced the contextual usefulness of vision only if we took account of time-delays. Our results shed light on critical features of dynamic manipulation distinct from those of static pinch, as well as the mechanism likely responsible for loss of manual dexterity and increased reliance on vision when age or neuromuscular disease increase noisiness and/or time-delays during sensorimotor integration.

    Objective The purpose of this study was to assess satisfaction with specific aspects of care for acute neck pain and explore the relationship between satisfaction with care, neck pain and global satisfaction. Methods This study was a secondary analysis of patient satisfaction from a randomized trial of spinal manipulation therapy (SMT) delivered by doctors of chiropractic, home exercise and advice (HEA) delivered by exercise therapists, and medication (MED) prescribed by a medical physician for acute/subacute neck pain. Differences in satisfaction with specific aspects of care were analyzed using a linear mixed model. The relationship between specific aspects of care and 1) change in neck pain (primary outcome of the randomized trial) and 2) global satisfaction were assessed using Pearson’s correlation and multiple linear regression. Results Individuals receiving SMT or HEA were more satisfied with the information and general care received than MED group participants. SMT and HEA groups reported similar satisfaction with information provided during treatment; however, the SMT group was more satisfied with general care. Satisfaction with general care (r=−0.75 to −0.77, R2= 0.55 to 0.56) had a stronger relationship with global satisfaction compared to satisfaction with information provided (r=−0.65 to 0.67, R2=0.39 to 0.46). The relationship between satisfaction with care and neck pain was weak (r=0.17 to 0.38, R2=0.08 to 0.21). Conclusions Individuals with acute/subacute neck pain were more satisfied with specific aspects of care from SMT delivered by doctors of chiropractic or HEA interventions compared to MED prescribed by a medical physician.

    NASA Astrophysics Data System (ADS)

    Kaiser, Laura; Pyrak-Nolte, Laura

    2014-03-01

    The fraction of the pore space in rock occupied by a given fluid is called saturation. The relationship between saturation and capillary pressure for porous media is hysteretic between imbibition and drainage cycles. If the wetting phase saturation increases, the capillary pressure follows an imbibition curve, and, if the wetting phase saturation decreases, the capillary pressure follows the drainage curve. Due to this hysteresis, researchers have suggested that there is a third variable that should be considered called interfacial area per volume that removes the ambiguity in the capillary pressure - saturation relationship. Before the relationship can be explored in more detail, we first must be able to manipulate the saturation internally rather than externally. We used electrowetting techniques to manipulate the contact angle of a salt water drop. This technique affects the interfacial energy and, therefore, enables manipulation of the contact angles and saturation. Once mastered, the technique could be used to explore the effect of interfacial area per volume on micromodel systems. NSF REU

    1992-06-01

    Flexible manipulators can be characterized by a dynamic model with a large number of vibration modes, and the use of the model in the model-based control schemes requires reduction of model order. Balanced truncation is an effective method for model reduction of asymptotically stable systems by transforming the states to a coordinate system in which the controllability and observability Gramians are equal and diagonal, and eliminating the states which contribute weakly to the input-output map. An elastic flexible manipulator, however, is a marginally stable system and thus the balanced truncation method can not be directly applied. Herein, a method is presented of reducing the order of a marginally stable system based on the fact that translation transformations in the frequency domain preserve input-output properties of the system. The successful application is addressed of the method to model reduction of flexible manipulators with infinite-dimensional for finite-dimensional model. The method is also applicable for any other marginally stable model, such as elastic space trusswork and multi-dimensional space vehicle structure.

  11. What is 'manipulation'? A reappraisal.

    PubMed

    Evans, David W; Lucas, Nicholas

    2010-06-01

    Due primarily to its colloquial function, 'manipulation' is a poor term for distinguishing one healthcare intervention from another. With reports continuing to associate serious adverse events with manipulation, particularly relating to its use in the cervical spine, it is essential that the term be used appropriately and in accordance with a valid definition. The purpose of this paper is to identify empirically-derived features that we propose to be necessary and collectively sufficient for the formation of a valid definition for manipulation. A final definition is not offered. However, arguments for and against the inclusion of features are presented. Importantly, these features are explicitly divided into two categories: the 'action' (that which the practitioner does to the recipient) and the 'mechanical response' (that which occurs within the recipient). The proposed features are: 1) A force is applied to the recipient; 2) The line of action of this force is perpendicular to the articular surface of the affected joint; 3) The applied force creates motion at a joint; 4) This joint motion includes articular surface separation; 5) Cavitation occurs within the affected joint.

    The biofilm mode of growth provides such significant advantages to the members of the consortium that most organisms in important habitats are found in biofilms. The study of factors that allow manipulation of biofilm microbes in the biofilm growth state requires that reproducible biofilms be generated. The most effective monitoring of biofilm formation, succession and desaturation is with on-line monitoring of microbial biofilms with flowcell for direct observation. The biofilm growth state incorporates a second important factor, the heterogeneity in distribution in time and space of the component members of the biofilm consortium. This heterogeneity is reflected not only in the cellular distribution but in the metabolic activity within a population of cells. Activity and cellular distribution can be mapped in four dimensions with confocal microscopy, and function can be ascertained by genetically manipulated reporter functions for specific genes or by vital stains. The methodology for understanding the microbial ecology of biofilms is now much more readily available and the capacity to manipulate biofilms is becoming an important feature of biotechnology.

    Acupuncture manipulation varies widely among practitioners in clinical settings, and it is difficult to teach novice students how to perform acupuncture manipulation techniques skillfully. The Acupuncture Manipulation Education System (AMES) is an open source software system designed to enhance acupuncture manipulation skills using visual feedback. Using a phantom acupoint and motion sensor, our method for acupuncture manipulation training provides visual feedback regarding the actual movement of the student's acupuncture manipulation in addition to the optimal or intended movement, regardless of whether the manipulation skill is lifting, thrusting, or rotating. Our results show that students could enhance their manipulation skills by training using this method. This video shows the process of manufacturing phantom acupoints and discusses several issues that may require the attention of individuals interested in creating phantom acupoints or operating this system.

    Otoliths play an important role in Zebrafish in terms of hearing and sense of balance. Many studies have been conducted to understand its structure and function, however the encoding of its movement in the brain remains unknown. Here we developed a noninvasive system capable of manipulating the otolith using optical trapping while we image its behavioral response and brain activity. We'll also present our tools for behavioral response detection and brain activity mapping. Acceleration is sensed through movements of the otoliths in the inner ear. Because experimental manipulations involve movements, electrophysiology and fluorescence microscopy are difficult. As a result, the neural codes underlying acceleration sensation are poorly understood. We have developed a technique for optically trapping otoliths, allowing us to simulate acceleration in stationary larval zebrafish. By applying forces to the otoliths, we can elicit behavioral responses consistent with compensation for perceived acceleration. Since the animal is stationary, we can use calcium imaging in these animals' brains to identify the functional circuits responsible for mediating responses to acceleration in natural settings.

    Robots involved in high value manipulation must be effectively coupled to a human operator either at the work-site or remotely connected via communication links. In order to make use of experimental performance evaluation data, models must be developed. Powerful models of remote manipulation by humans can be used to predict manipulation performance in future systems based on today's laboratory systems. In this paradigm, the models are developed from experimental data, and then used to predict performance in slightly different situations. Second, accurate telemanipulation will allow design of manipulation systems which extend manipulation capability beyond its current bounds.

    The operator's ability to perform five manipulator tip movements while using monoptic and stereoptic video systems was assessed. Test data obtained were compared with previous results to determine the impact of camera placement and stereoptic viewing on manipulator system performance. The tests were performed using the NASA MSFC extendible stiff arm Manipulator and an analog joystick controller. Two basic manipulator tasks were utilized. The minimum position change test required the operator to move the manipulator arm to touch a target contract. The dexterity test required removal and replacement of pegs.

    Sub-grouping of low back pain (LBP) is believed to improve prediction of prognosis and treatment effects. The objectives of this study were: (1) to examine whether chiropractic patients could be sub-grouped according to an existing pathoanatomically-based classification system, (2) to describe patient characteristics within each subgroup, and (3) to determine the proportion of patients in whom clinicians considered the classification to be unchanged after approximately 10 days. A cohort of 923 LBP patients was included during their first consultation. Patients completed an extensive questionnaire and were examined according to a standardised protocol. Based on the clinical examination, patients were classified into diagnostic subgroups. After approximately 10 days, chiropractors reported whether they considered the subgroup had changed. The most frequent subgroups were reducible and partly reducible disc syndromes followed by facet joint pain, dysfunction and sacroiliac (SI)-joint pain. Classification was inconclusive in 5% of the patients. Differences in pain, activity limitation, and psychological factors were small across subgroups. Within 10 days, 82% were reported to belong to the same subgroup as at the first visit. In conclusion, LBP patients could be classified according to a standardised protocol, and chiropractors considered most patient classifications to be unchanged within 10 days. Differences in patient characteristics between subgroups were very small, and the clinical relevance of the classification system should be investigated by testing its value as a prognostic factor or a treatment effect modifier. It is recommended that this classification system be combined with psychological and social factors if it is to be useful.

    2016-01-01

    Objective: We explored if any predictors of success could be identified from end-of-year grades in a chiropractic master's program and whether these grades could predict final-year grade performance and year-on-year performance. Methods: End-of-year average grades and module grades for a single cohort of students covering all academic results for years 1–4 of the 2013 graduating class were used for this analysis. Analysis consisted of within-year correlations of module grades with end-of-year average grades, linear regression models for continuous data, and logistic regression models for predicting final degree classifications. Results: In year 1, 140 students were enrolled; 85.7% of students completed the program 4 years later. End-of-year average grades for years 1–3 were correlated (Pearson r values ranging from .75 to .87), but the end-of-year grades for years 1–3 were poorly correlated with clinic internship performance. In linear regression, several modules were predictive of end-of-year average grades for each year. For year 1, logistic regression showed that the modules Physiology and Pharmacology and Investigative Imaging were predictive of year 1 performance (odds ratio [OR] = 1.15 and 0.9, respectively). In year 3, the modules Anatomy and Histopathology 3 and Problem Solving were predictors of the difference between a pass/merit or distinction final degree classification (OR = 1.06 and 1.12, respectively). Conclusion: Early academic performance is weakly correlated with final-year clinic internship performance. The modules of Anatomy and Histopathology year 3 and Problem Solving year 3 emerged more consistently than other modules as being associated with final-year classifications. PMID:26076397

    An important influence on parents' decisions about pediatric vaccination (children under 6 years of age) is the attitude of their health care providers, including complementary and alternative medicine (CAM) providers. Very limited qualitative research exists, however, on how attitudes towards vaccination develop among healthcare professionals in-training. We explored perspective development among three groups of students: medical, chiropractic, and naturopathic. We conducted focus group sessions with participants from each year of study at three different healthcare training programs in Ontario, Canada. Semi-structured and open-ended questions were used to elicit dynamic interaction among participants and explore how they constructed their attitudes toward vaccination at the beginning and part way through their professional training. Analyses of verbatim transcripts of audiotaped interviews were conducted both inductively and deductively using questions structured by existing literature on learning, professional socialization and interprofessional relations. We found five major themes and each theme was illustrated with representative quotes. Numerous unexpected insights emerged within these themes, including students' general open-mindedness towards pediatric vaccination at the beginning of their training; the powerful influence of both formal education and informal socialization; uncritical acceptance of the vaccination views of senior or respected professionals; students' preference for multiple perspectives rather than one-sided, didactic instruction; the absence of explicit socio-cultural tensions among professions; and how divergences among professional students' perspectives result from differing emphases with respect to lifestyle, individual choice, public health and epidemiological factors-rather than disagreement concerning the biomedical evidence. This last finding implies that their different perspectives on pediatric vaccination may be complementary

    Objective Manipulation under anesthesia (MUA) is an outpatient procedure that is performed to restore normal joint kinematics and musculoskeletal function. This article presents a case of a patient with idiopathic lumbar degenerative scoliosis who developed intractable pain as an adult and reports on the outcomes following a trial of MUA. Clinical Features A 59-year-old female patient presented to a chiropractic office with primary subjective symptoms of lower back and bilateral hip pain. Numerical pain rating scores were reported at 8 of 10 for the lower back and 9 of 10 for the sacroiliac joint/gluteal region. A disability score using a functional rating index demonstrated a score of 26 of 40 (or 64% disability). Over the preceding 5 years, the patient had tried a number of conservative therapies to relieve her pain without success. Intervention and Outcome The patient was evaluated for MUA. The patient was scheduled for a serial MUA over 3 days. Numerical pain rating scores 8 weeks after the MUA were 1 of 10 for the lower back and 3 of 10 for the sacroiliac joint. Her disability rating decreased to 11 of 40 (28%). Radiological improvements were also observed. These outcomes were maintained at 6-month follow-up. Conclusion Pain, functional, and radiographic outcomes demonstrated improvements immediately following treatment for this patient. PMID:21629554

    Spin dynamics of polarized deuteron beams near depolarization resonances, including a new polarization preservation concept based on specially-designed multiple resonance crossings, has been tested in a series of experiments in the COSY synchrotron. Intricate spin dynamics with sophisticated pre-programmed patterns as well as effects of multiple crossings of a resonance were studied both theoretically and experimentally with excellent agreement. Possible applications of these results to preserve, manipulate and spin-flip polarized beams in synchrotrons and storage rings are discussed.

    The precise manipulation of small particles is not a trivial task. In a first effort, a nanorobot system was built based on a robot with vision feedback and a micromachined gripper. It was suitable for handling particles down to 100 μ with submicron accuracy in a normal environment. For smaller particles stiction effects prohibit the release of the particles in a controlled way. Stiction effects are avoided in a fluid environment. As an example, a system of channels is described in detail that is able to feed micron sized particles in a fluid environment to the desired places.

    Use of probability of collision (Pc) has brought sophistication to CA. Made possible by JSpOC precision catalogue because provides covariance. Has essentially replaced miss distance as basic CA parameter. Embrace of Pc has elevated methods to 'manipulate' covariance to enable/improve CA calculations. Two such methods to be examined here; compensation for absent or unreliable covariances through 'Maximum Pc' calculation constructs, projection (not propagation) of epoch covariances forward in time to try to enable better risk assessments. Two questions to be answered about each; situations to which such approaches are properly applicable, amount of utility that such methods offer.

    Abstract Objective The purpose of this case report is to describe the response to chiropractic care of a pediatric patient with complaints of neck pain; headaches; and hand, leg, and foot pain after head trauma and the reports of changes in the patient's history of chronic fatigue, vomiting, and coughing. Clinical Features A 6-year–old girl was pushed into a playground slide, hitting her head and resulting in acute complaints of her “neck and brain hurting” and hand, foot, and occasional leg pain. In addition, the patient had a several-year history of unexplained fatigue, vomiting, and coughing spells. She had a neck pain disability index of 17.8%; left lateral and rotational head tilt; cervical antalgic lean; loss of cervical range of motion; anterior cervical translation; and spasm, tenderness, trigger points, and edema along the cervical and thoracic spine. Intervention and Outcome The patient was cared for using Activator Methods protocol. After the fifth treatment, all the patient's symptoms dissipated, with a complete return to normal activity and spinal stability after 9 treatments. At 19 weeks, her spine continued to be asymptomatic; and her neck disability index was 0%. Conclusion This case demonstrated that the Activator Method of chiropractic care had a beneficial effect for this pediatric patient. PMID:19703669

    Objective To compare chiropractic students' perceptions of preparedness for practice before and after a clinical placement in Rarotonga and to report demographics from these experiences. Methods The students completed deidentified pre- and postplacement surveys assessing pediatric practice preparedness. Students tallied the patient numbers, age, and chiropractic techniques used per visit for each day of clinic placement. On completion of the program, participating students (27/34, or 79% of the student cohort) did a postplacement survey on their perception of practice preparedness. Data were analyzed with the Spearman rho correlation, the Mann-Whitney U test, and regression analysis. Results There was an increase in perceived preparedness for pediatric practice, ranging from 24.1% of the student cohort at the start of the study to 82.1% following clinical placement in Rarotonga. The change in student preparedness to practice with children was positively correlated with the total number of children managed (rs = .05, p = .01) and the number of children managed who were under 10 years of age (rs = .60, p = .001). Multiple regression analysis demonstrated a medium positive effect for postprogram preparedness (F [4, 20] = 3.567, p = .024). Conclusion Clinical outreach to Rarotonga provided a broad case mix of patients and a change in student perceptions of preparedness to practice with children, which was positively affected by the total number of children managed and the number of children managed who were under 10 years of age.

    Objective: We investigated the self-reported barriers to publication for authors of abstracts presented at the most recent chiropractic scientific meetings for which publication rates are known, that is the 2006 to 2008 Association of Chiropractic Colleges Educational Conference and Research Agenda Conference (ACC/RAC) meetings. Methods A 4-question electronic survey was sent via email to 1 of the listed authors for each abstract not published as a full paper within 4 years of the 2006 to 2008 ACC/RAC meetings. Each author was asked to complete the survey for only 1 abstract. Taking into account authors who appeared on more than 1 abstract, a link to the electronic survey was emailed to 111 potential participants. Results Of 111 participants, 67 completed a survey for a return rate of 60%. Over 80% (55/67) of the respondents were chiropractors who were faculty members at educational institutions. Of the subjects, 30% (20/67) indicated that the meeting abstract had either been published after 2012 or still was in the publishing process. For those who had not submitted a manuscript for publication, the most frequently cited barriers to publishing were pursuit of publishing as a low priority followed by a lack of time to prepare a manuscript. Conclusion The main barriers to publishing in this sample were that publishing had a low priority compared to other possible uses of the abstract author's time and a perceived lack of time to pursue the publication process.

Clinical features A 38-year-old man presented to a chiropractic clinic with neck pain and a history of an anterior cervical spine plate fusion at C6-7 after a work related accident 4 years earlier. He had signs and symptoms of spondolytic myelopathy and right lower back, right posterior thigh pain and numbness. Intervention and outcome The patient was treated with Cox technique and rehabilitation. The patient experienced a reduction of pain on a numeric pain scale from 8/10 to 3/10. The patient was seen a total of 12 visits over 3 months. No adverse effects were reported. Conclusions A patient with a prior C6-7 fusion with spondylotic myelopathy and concurrent L5-S1 radiculopathy improved after a course of rehabilitation and Cox distraction manipulation. Further research is needed to establish its efficiency. PMID:25685119

    Plant vacuoles have multifaceted roles including turgor maintenance, cytosolic pH and ionic homeostasis, plant protection against environmental stress, detoxification, pigmentation, and cellular signaling. These roles are achieved through the coordinated activities of many proteins in the tonoplast (vacuolar membrane), of which the proton pumps and ion transporters have been modified for improved abiotic stress tolerance in transgenic plants. Here we describe a method to manipulate vacuolar H(+)-pyrophosphatase in turfgrass and evaluate the impact of the modified tonoplast on the phenotype, biochemistry, and physiology of the transgenics. Creeping bentgrass (Agrostis stolonifera L.) plants overexpressing an Arabidopsis vacuolar H(+)-pyrophosphatase AVP1 exhibited improved growth and enhanced salt tolerance, likely associated with increased photosynthesis, relative water content, proline production, and Na(+) uptake. These transgenic plants also had decreased solute leakage in the leaf tissues and increased concentrations of Na(+), K(+), Cl(-), and total phosphorus in the root tissues. Similar strategies can be employed to manipulate other tonoplast transporters and in other plant species to produce transgenic plants with improved performance under various abiotic stresses.

    A mobile remote manipulator system is disclosed for assembly, repair and logistics transport on, around and about a space station square bay truss structure. The vehicle is supported by a square track arrangement supported by guide pins integral with the space station truss structure and located at each truss node. Propulsion is provided by a central push-pull drive mechanism that extends out from the vehicle one full structural bay over the truss and locks drive rods into the guide pins. The draw bar is now retracted and the mobile remote manipulator system is pulled onto the next adjacent structural bay. Thus, translation of the vehicle is inchworm style. The drive bar can be locked onto two guide pins while the extendable draw bar is within the vehicle and then push the vehicle away one bay providing bidirectional push-pull drive. The track switches allow the vehicle to travel in two orthogonal directions over the truss structure which coupled with the bidirectional drive, allow movement in four directions on one plane. The top layer of this trilayered vehicle is a logistics platform. This platform is capable of 369 degees of rotation and will have two astronaut foot restraint platforms and a space crane integral.

    The robotic manipulator can be decomposed into distinct subsytems. One particular area of interest of mechanical subsystems is electromechanical actuators (or drives). A drive is defined as a motor with an appropriate transmission. An overview is given of existing, as well as state-of-the-art drive systems. The scope is limited to space applications. A design philosophy and adequate requirements are the initial steps in designing a space-qualified actuator. The focus is on the d-c motor in conjunction with several types of transmissions (harmonic, tendon, traction, and gear systems). The various transmissions will be evaluated and key performance parameters will be addressed in detail. Included in the assessment is a shuttle RMS joint and a MSFC drive of the Prototype Manipulator Arm. Compound joints are also investigated. Space imposes a set of requirements for designing a high-performance drive assembly. Its inaccessibility and cryogenic conditions warrant special considerations. Some guidelines concerning these conditions are present. The goal is to gain a better understanding in designing a space actuator.

    Hejduk, M. D.

    2016-01-01

    The manipulation of space object covariances to try to provide additional or improved information to conjunction risk assessment is not an uncommon practice. Types of manipulation include fabricating a covariance when it is missing or unreliable to force the probability of collision (Pc) to a maximum value ('PcMax'), scaling a covariance to try to improve its realism or see the effect of covariance volatility on the calculated Pc, and constructing the equivalent of an epoch covariance at a convenient future point in the event ('covariance forecasting'). In bringing these methods to bear for Conjunction Assessment (CA) operations, however, some do not remain fully consistent with best practices for conducting risk management, some seem to be of relatively low utility, and some require additional information before they can contribute fully to risk analysis. This study describes some basic principles of modern risk management (following the Kaplan construct) and then examines the PcMax and covariance forecasting paradigms for alignment with these principles; it then further examines the expected utility of these methods in the modern CA framework. Both paradigms are found to be not without utility, but only in situations that are somewhat carefully circumscribed.

    When high-dimensional data is visualized in a 2D plane by using parametric projection algorithms, users may wish to manipulate the layout of the data points to better reflect their domain knowledge or to explore alternative structures. However, few users are well-versed in the algorithms behind the visualizations, making parameter tweaking more of a guessing game than a series of decisive interactions. Translating user interactions into algorithmic input is a key component of Visual to Parametric Interaction (V2PI) [13]. Instead of adjusting parameters, users directly move data points on the screen, which then updates the underlying statistical model. However, we have found that some data points that are not moved by the user are just as important in the interactions as the data points that are moved. Users frequently move some data points with respect to some other 'unmoved' data points that they consider as spatially contextual. However, in current V2PI interactions, these points are not explicitly identified when directly manipulating the moved points. We design a richer set of interactions that makes this context more explicit, and a new algorithm and sophisticated weighting scheme that incorporates the importance of these unmoved data points into V2PI.

    A relatively simple, modular, low mass, low cost robot is being developed for space EVA that is large enough to be independently mobile on a space station or platform exterior, yet versatile enough to accomplish many vital tasks. The robot comprises two long flexible links connected by a rotary joint, with 2-DOF 'wrist' joints and grippers at each end. It walks by gripping pre-positioned attachment points, such as trusswork nodes, and alternately shifting its base of support from one foot (gripper) to the other. The robot can perform useful tasks such as visual inspection, material transport, and light assembly by manipulating objects with one gripper, while stabilizing itself with the other. At SOAR '90, we reported development of 1/3 scale robot hardware, modular trusswork to serve as a locomotion substrate, and a gravity compensation system to allow laboratory tests of locomotion strategies on the horizontal face of the trusswork. In this paper, we report on project progress including the development of: (1) adaptive control for automatic adjustment to loads; (2) enhanced manipulation capabilities; (3) machine vision, including the use of neural nets, to guide autonomous locomotion; (4) locomotion between orthogonal trusswork faces; and (5) improved facilities for gravity compensation and telerobotic control.

    A six degree-of-freedom computer-controlled manipulator is examined, and the relationships between the arm's joint variables and 3-space are derived. Arm trajectories using sequences of third-degree polynomials to describe the time history of each joint variable are presented and two approaches to the avoidance of obstacles are given. The equations of motion for the arm are derived and then decomposed into time-dependent factors and time-independent coefficients. Several new and simplifying relationships among the coefficients are proven. Two sample trajectories are analyzed in detail for purposes of determining the most important contributions to total force in order that relatively simple approximations to the equations of motion can be used.

    Infertility studies are an important growing field, where new methods for the manipulation, enrichment and selection of sperm cells are required. Microfluidic techniques offer attractive advantages such as requirement of low sample volume and short processing times in the range of second or minutes. Presented here is the application of insulator-based dielectrophoresis (iDEP) for the enrichment and separation of mature and spermatogenic cells by employing a microchannel with cylindrical insulating structures with DC electric potentials in the range of 200-1500 V. The results demonstrated that iDEP has the potential to concentrate sperm cells and distinguish between mature and spermatogenic cells by exploiting the differences in shape which lead to differences in electric polarization. Viability assessments revealed that a significant percentage of the cells are viable after the dielectrophoretic treatment, opening the possibility for iDEP to be developed as a tool in infertility studies.

    A prototype of the RIPS architecture (Robotic Instruction Processing System) was developed. A two arm robot control experiment is underway to characterize the architecture as well as research multi-arm control. This experiment uses two manipulators to cooperatively position an object. The location of the object is specified by the host computer's mouse. Consequently, real time kinematics and dynamics are necessary. The RIPS architecture is specialized so that it can satisfy these real time constraints. The two arm experimental set-up is discussed. A major part of this work is the continued development of a good programming environment for RIPS. The C++ language is employed and favorable results exist in the targeting of this language to the RIPS hardware.

    Research has been conducted on developing the theoretical basis and the technology for a Reconfigurable Modular Manipulation System (RMMS). Unlike a conventional manipulator which has a fixed configuration, the RMMS consists of a set of interchangeable modules that can be rapidly assembled into a system of manipulators with appropriate configurations depending on the specific task requirement. For effective development and use of such a versatile and flexible system a program of theoretical and experimental research has been pursued aimed at developing the basis for next generation of autonomous manipulator systems. The RMMS concept extends the idea of autonomy from sensor-based to configuration based autonomy. One of the important components is the development of design methodologies for mapping tasks into manipulator configurations and for automatic generation of manipulator specific algorithms (e.g., kinematics and dynamics) in order to make the hardware transparent to the user.(JDB)

While manual therapy has shown reasonable success in symptomatic management of these cases, little information is known how manual therapy may affect the structure and function of the lumbar disc itself. In cases where lumbar disc herniation is accompanied by radicular symptoms, electrodiagnostic testing has been used to provide objective clinical information on nerve function. This report examines the treatment rendered for a patient with lower extremity neurological deficit, as diagnosed on electrodiagnostic testing. Patient was treated using spinal manipulation and exercises performed on a Pettibon Wobble Chair™, using electrodiagnostic testing as the primary outcome assessment. Case Presentation An elderly male patient presented to a private spine clinic with right-sided foot drop. He had been prescribed an ankle-foot orthosis for this condition. All sensory, motor, and reflex findings in the right leg and foot were absent. This was validated on prior electromyography and nerve conduction velocity testing, performed by a board certified neurologist. Patient was treated using spinal manipulation twice-weekly and wobble chair exercises three times daily for 90 days total. Following this treatment, the patient was referred for follow-up electrodiagnostic studies. Significant improvements were made in these studies as well as self-rated daily function. Conclusion Motion-based therapies, as part of a comprehensive rehabilitation program, may contribute to the restoration of daily function and the reversal of neurological insult as detected by electrodiagnostic testing. Electrodiagnostic testing may be a useful clinical tool to evaluate the progress of chiropractic patients with lumbar disc herniation and radicular pain syndromes. PMID:16968536

    Objectives Manual therapy practitioners commonly assess lumbar intervertebral mobility before deciding treatment regimens. Changes in mechanoreceptor activity during the manipulative thrust are theorized to be an underlying mechanism of spinal manipulation (SM) efficacy. The objective of this study was to determine if facet fixation or facetectomy at a single lumbar level alters muscle spindle activity during 5 SM thrust durations in an animal model. Methods Spinal stiffness was determined using the slope of a force-displacement curve. Changes in the mean instantaneous frequency of spindle discharge were measured during simulated SM of the L6 vertebra in the same 20 afferents for laminectomy-only, 19 laminectomy & facet screw conditions; only 5 also had data for the laminectomy & facetectomy condition. Neural responses were compared across conditions and five thrust durations (≤ 250ms) using linear mixed models. Results Significant decreases in afferent activity between the laminectomy-only and laminectomy & facet screw conditions were seen during 75ms (P<.001), 100ms (P=.04) and 150ms (P=.02) SM thrust durations. Significant increases in spindle activity between the laminectomy-only and laminectomy & facetectomy conditions were seen during the 75ms (P<.001) and 100ms (P<.001) thrust durations. Conclusion Intervertebral mobility at a single segmental level alters paraspinal sensory response during clinically relevant high velocity low amplitude SM thrust durations (≤150ms). The relationship between intervertebral joint mobility and alterations of primary afferent activity during and following various manual therapy interventions may be used to help to identify patient subpopulations who respond to different types of manual therapy and better inform practitioners (eg, chiropractic, osteopathic) delivering the therapeutic intervention.

  20. Virus manipulation of cell cycle.

    Nascimento, R; Costa, H; Parkhouse, R M E

    Viruses depend on host cell resources for replication and access to those resources may be limited to a particular phase of the cell cycle. Thus manipulation of cell cycle is a commonly employed strategy of viruses for achieving a favorable cellular environment. For example, viruses capable of infecting nondividing cells induce S phase in order to activate the host DNA replication machinery and provide the nucleotide triphosphates necessary for viral DNA replication (Flemington in J Virol 75:4475-4481, 2001; Sullivan and Pipas in Microbiol Mol Biol Rev 66:179-202, 2002). Viruses have developed several strategies to subvert the cell cycle by association with cyclin and cyclin-dependent kinase complexes and molecules that regulate their activity. Viruses tend to act on cellular proteins involved in a network of interactions in a way that minimal protein-protein interactions lead to a major effect. The complex and interactive nature of intracellular signaling pathways controlling cell division affords many opportunities for virus manipulation strategies. Taking the maxim "Set a thief to catch a thief" as a counter strategy, however, provides us with the very same virus evasion strategies as "ready-made tools" for the development of novel antivirus therapeutics. The most obvious are attenuated virus vaccines with critical evasion genes deleted. Similarly, vaccines against viruses causing cancer are now being successfully developed. Finally, as viruses have been playing chess with our cell biology and immune responses for millions of years, the study of their evasion strategies will also undoubtedly reveal new control mechanisms and their corresponding cellular intracellular signaling pathways.

    A figure depicts a prototype of a robotic-manipulator gripping device that includes two passive compliant fingers, suitable for picking up and manipulating objects that have irregular shapes and/or that are, themselves, compliant. The main advantage offered by this device over other robotic-manipulator gripping devices is simplicity: Because of the compliance of the fingers, force-feedback control of the fingers is not necessary for gripping objects of a variety of sizes, shapes, textures, and degrees of compliance. Examples of objects that can be manipulated include small stones, articles of clothing, and parts of plants.

    The direct manipulation of embryonic cells is an important tool for addressing key questions in cell and developmental biology. C. elegans is relatively unique among genetic model systems in being amenable to manipulation of embryonic cells. Embryonic cell manipulation has allowed the identification of cell interactions by direct means, and it has been an important technique for dissecting mechanisms by which cell fates are specified, cell divisions are oriented, and morphogenesis is accomplished. Here, we present detailed methods for isolating, manipulating and culturing embryonic cells of C. elegans. PMID:22226523

  6. Kinematics and Control of Robot Manipulators

    NASA Astrophysics Data System (ADS)

    Paden, Bradley Evan

    This dissertation focuses on the kinematics and control of robot manipulators. The contribution to kinematics is a fundamental theorem on the design of manipulators with six revolute joints. The theorem states, roughly speaking, that manipulators which have six revolute joints and are modeled after the human arm are optimal and essentially unique. In developing the mathematical framework to prove this theorem, we define precisely the notions of length of a manipulator, well-connected-workspace, and work-volume. We contribute to control a set of analysis techniques for the design of variable structure (sliding mode) controllers for manipulators. The organization of the dissertation is the following. After introductory remarks in chapter one, the group of proper rigid motions, G, is introduced in chapter two. The tangent bundle of G is introduced and it is shown that the velocity of a rigid body can be represented by an element in the Lie algebra of G (commonly called a twist). Further, rigid motions which are exponentials of twists are used to describe four commonly occurring subproblems in robot kinematics. In chapter three, the exponentials of twists are used to write the forward kinematic map of robot manipulators and the subproblems of chapter two are used to solve the Stanford manipulator and an elbow manipulator. Chapter four focuses on manipulator singularities. Twist coordinates are used to find critical points of the forward kinematic map. The contribution to kinematics is contained in chapter five where a mathematical framework for studying the relationship between the design of 6R manipulators and their performance is developed. Chapter seven contains the contribution to control. The work of A. F. Filippov on differential equations with discontinuous right-hand-side and the work of F. H. Clarke on generalized gradients are combined to obtain a calculus for analyzing nonsmooth gradient systems. The techniques developed are applied to design a simple

    1986-04-01

    Spinal manipulation or manual therapy is becoming an increasingly popular method of treating athletes with spinal problems. The primary theoretic basis for the claimed beneficial results of manipulation is the restoration of motion with subsequent effect on ligamentous adhesions, muscle spasm, disk nutrition, and central nervous system endorphin systems. The concept of joint barriers has been developed to differentiate among exercise therapy, mobilization, and manipulation. Research trials suggest that spinal manipulation is beneficial in relieving or reducing the duration of acute low back pain and acute neck pain but has much less effect on chronic low back pain and neck pain. There is evidence that manipulation increases certain parameters of motion of the spine but this evidence is not yet conclusive. There are a wide variety of manipulative procedures that are utilized to manipulate the spine to increase range of motion, and the selection of the procedures is based on manual diagnostic skills. Manipulation, however, is not a benign procedure and has been implicated in the aggravation of disk herniation or bony fractures as well as the precipitation of vertebrobasilar artery occlusion.

    Giardia lamblia is a flagellated protozoan that infects several species including humans and is a major agent of waterborne outbreaks of diarrhea. G. lamblia is also important in the study of basic eukaryotic molecular biology and evolution; however, it has been difficult to employ standard genetic methods in the study of Giardia. Over the past 6 years, two transfection systems were developed and used for the genetic manipulation of G. lamblia. Both systems allow transient or stable transfection of Giardia and/or foreign genes. The DNA-based transfection system allows electroporation of circular or linear plasmid DNA into trophozoites. The RNA virus-based transfection system requires electroporation of in vitro transcribed RNA into GLV-infected trophozoites. Because G. lamblia is one of the most rudimentary eukaryotes, its processes of transcription, translation and protein transport, as well as its metabolic and biochemical pathways, are of interest. Study of these areas will continue to be advanced using transfection in combination with cellular and molecular tools. Several groups have combined these technologies with other techniques to study protein transport and the transcriptional and post-transcriptional regulation of Giardia genes, including encystation-specific and variant surface protein genes. In addition, coupling antisense techniques with transfection has permitted functional knockout of Giardia metabolic genes, allowing Giardia metabolic pathways to be studied. In the near future, both transfection systems will be potent tools in our investigations of the perplexing questions in Giardia biology.

    An overview of research on a flow control technique called Coanda-assisted Spray Manipulation (CSM) is presented. CSM uses a high-momentum control jet under the influence of the Coanda effect to vector a high volume-flow jet or spray. Actuators provide the capability of moving the location of applied control flow making rotary or arbitrary motion of the vectored flow possible. The presented work includes a fundamental isothermal study on the effects of rotation speed and Reynolds number on a vectored jet using a belt-driven CSM actuator. Three-component velocity data were acquired for three Reynolds numbers and three rotation speeds using timed resolved high-speed stereo Particle Image Velocimetry. A second CSM system with 16 pneumatically-driven control ports has been retrofitted to a flame spray gun. This combination provides the capability to rapidly alter the direction of applied metal powders. High speed video of this process will also be presented. Finally, a fundamental study on the pneumatic system's response to minor losses and connection lines of varying lengths is presented.

    Organic photovoltaics (OPVs) hold great promise for next-generation photovoltaics in renewable energy because of the potential to realize low-cost mass production via large-area roll-to-roll printing technologies on flexible substrates. To achieve high-efficiency OPVs, one key issue is to overcome the insufficient photon absorption in organic photoactive layers, since their low carrier mobility limits the film thickness for minimized charge recombination loss. To solve the inherent trade-off between photon absorption and charge transport in OPVs, the optical manipulation of light with novel micro/nano-structures has become an increasingly popular strategy to boost the light harvesting efficiency. In this Review, we make an attempt to capture the recent advances in this area. A survey of light trapping schemes implemented to various functional components and interfaces in OPVs is given and discussed from the viewpoint of plasmonic and photonic resonances, addressing the external antireflection coatings, substrate geometry-induced trapping, the role of electrode design in optical enhancement, as well as optically modifying charge extraction and photoactive layers.

    PubMed

    Beare, Paul A

    2012-01-01

    Until very recently, Coxiella burnetii was viewed and studied as an obligate intracellular bacterium that relied exclusively on a eucaryotic host cell for growth. Other medically relevant obligate intracellular bacteria reside in the genera Anaplasma, Chlamydia, Ehrlichia, Orientia, and Rickettsia. An obligate intracellular lifestyle presents a significant obstacle to genetic transformation. Procedures that are straightforward with free-living bacteria, such as antibiotic selection and cloning, can be very difficult when growth of transformants is restricted to a host cell. Long-term passage in host cells to expand small transformant populations can further complicate the procedure. Despite these and other obstacles, at least rudimentary systems are currently available for genetic transformation of most obligate intracellular bacterial pathogens. Dramatically aiding the development of new genetic methods for C. burnetii is the recent discovery of a medium that supports host cell-free growth of the organism in liquid, and importantly, on solid media as clonal colonies. The expanded C. burnetii genetics toolbox now includes transposon systems for random mutagenesis and single-copy, site-specific chromosomal gene knock-ins, as well as a shuttle vector for heterologous gene expression and in trans complementation. A reliable method of targeted gene inactivation remains a challenge. Advances in C. burnetii genetic manipulation will allow identification of genes essential for intracellular parasitism and disease pathogenesis, and undoubtedly fuel new interest in this minimally studied bacterial pathogen.

    The system is designed for manipulation, analysis, interpretation, and processing of a wide variety of image data. LANDSAT (ERTS) and other data in digital form can be input directly into the system. Photographic prints and transparencies are first converted to digital form with an on-line high-resolution microdensitometer. The system is implemented on a Hewlett-Packard 3000 computer with 128 K bytes of core memory and a 47.5 megabyte disk. It includes a true color display monitor, with processing memories, graphics overlays, and a movable cursor. Image data formats are flexible so that there is no restriction to a given set of remote sensors. Conversion between data types is available to provide a basis for comparison of the various data. Multispectral data is fully supported, and there is no restriction on the number of dimensions. In this way multispectral data collected at more than one point in time may simply be treated as a data collected with twice (three times, etc.) the number of sensors. There are various libraries of functions available to the user: processing functions, display functions, system functions, and earth resources applications functions.

    Optical trapping has successfully been applied to select and mount microcrystals for subsequent X-ray diffraction experiments. X-ray crystallography is the method of choice to deduce atomic resolution structural information from macromolecules. In recent years, significant investments in structural genomics initiatives have been undertaken to automate all steps in X-ray crystallography from protein expression to structure solution. Robotic systems are widely used to prepare crystallization screens and change samples on synchrotron beamlines for macromolecular crystallography. The only remaining manual handling step is the transfer of the crystal from the mother liquor onto the crystal holder. Manual mounting is relatively straightforward for crystals with dimensions of >25 µm; however, this step is nontrivial for smaller crystals. The mounting of microcrystals is becoming increasingly important as advances in microfocus synchrotron beamlines now allow data collection from crystals with dimensions of only a few micrometres. To make optimal usage of these beamlines, new approaches have to be taken to facilitate and automate this last manual handling step. Optical tweezers, which are routinely used for the manipulation of micrometre-sized objects, have successfully been applied to sort and mount macromolecular crystals on newly designed crystal holders. Diffraction data from CPV type 1 polyhedrin microcrystals mounted with laser tweezers are presented.

    1990-01-01

    Modeling, simulation, and analysis of robot manipulators with non-negligible joint flexibility are studied. A recursive Newton-Euler model of the flexibly jointed manipulator is developed with many advantages over the traditional Lagrange-Euler methods. The Newton-Euler approach leads to a method for the simulation of a flexibly jointed manipulator in which the number of computations grows linearly with the number of links. Additionally, any function for the flexibility between the motor and link may be used permitting the simulation of nonlinear effects, such as backlash, in a uniform manner for all joints. An analysis of the control problems for flexibly jointed manipulators is presented by converting the Newton-Euler model to a Lagrange-Euler form. The detailed structure available in the model is used to examine linearizing controllers and shows the dependency of the control on the choice of flexible model and structure of the manipulator.

    Damping control is applied to a detailed computer model of a long- reach flexible manipulator test bed. The test bed consists of a long slender link with a dexterous manipulator mounted at its tip. The movement of the dexterous manipulator is controlled to create inertial damping forces on the long link. Parameter identification and sequential loop-closure are used to design a controller that feeds back relative tip position and velocity of the long link to control the azimuth angle of the dexterous manipulator. The controller is designed to be robust to varying manipulator loading conditions and reliable under sensor failures.

  3. Perspectives of older adults on co-management of low back pain by doctors of chiropractic and family medicine physicians: a focus group study

    2013-01-01

    Background While older adults may seek care for low back pain (LBP) from both medical doctors (MDs) and doctors of chiropractic (DCs), co-management between these providers is uncommon. The purposes of this study were to describe the preferences of older adults for LBP co-management by MDs and DCs and to identify their concerns for receiving care under such a treatment model. Methods We conducted 10 focus groups with 48 older adults who received LBP care in the past year. Interviews explored participants’ care seeking experiences, co-management preferences, and perceived challenges to successful implementation of a MD-DC co-management model. We analyzed the qualitative data using thematic content analysis. Results Older adults considered LBP co-management by MDs and DCs a positive approach as the professions have complementary strengths. Participants wanted providers who worked in a co-management model to talk openly and honestly about LBP, offer clear and consistent recommendations about treatment, and provide individualized care. Facilitators of MD-DC co-management included collegial relationships between providers, arrangements between doctors to support interdisciplinary referral, computer systems that allowed exchange of health information between clinics, and practice settings where providers worked in one location. Perceived barriers to the co-management of LBP included the financial costs associated with receiving care from multiple providers concurrently, duplication of tests or imaging, scheduling and transportation problems, and potential side effects of medication and chiropractic care. A few participants expressed concern that some providers would not support a patient-preferred co-managed care model. Conclusions Older adults are interested in receiving LBP treatment co-managed by MDs and DCs. Older adults considered patient-centered communication, collegial interdisciplinary interactions between these providers, and administrative supports such as

    The STarT back screening tool (SBT) allocates low back pain (LBP) patients into three risk groups and is intended to assist clinicians in their decisions about choice of treatment. The tool consists of domains from larger questionnaires that previously have been shown to be predictive of non-recovery from LBP. This study was performed to describe the distribution of depression, fear avoidance and catastrophising in relation to the SBT risk groups. A total of 475 primary care patients were included from 19 chiropractic clinics. They completed the SBT, the Major Depression Inventory (MDI), the Fear Avoidance Beliefs Questionnaire (FABQ), and the Coping Strategies Questionnaire. Associations between the continuous scores of the psychological questionnaires and the SBT were tested by means of linear regression, and the diagnostic performance of the SBT in relation to the other questionnaires was described in terms of sensitivity, specificity and likelihood ratios.In this cohort 59% were in the SBT low risk, 29% in the medium risk and 11% in high risk group. The SBT risk groups were positively associated with all of the psychological questionnaires. The SBT high risk group had positive likelihood ratios for having a risk profile on the psychological scales ranging from 3.8 (95% CI 2.3 - 6.3) for the MDI to 7.6 (95% CI 4.9 - 11.7) for the FABQ. The SBT questionnaire was feasible to use in chiropractic practice and risk groups were related to the presence of well-established psychological prognostic factors. If the tool proves to predict prognosis in future studies, it would be a relevant alternative in clinical practice to other more comprehensive questionnaires.

  5. Dynamics and Manipulation of Nanomagnets

    NASA Astrophysics Data System (ADS)

    Cai, Liufei

    This thesis presents my work on the spin dynamics of nanomagnets and investigates the possibility of manipulating nanomagnets by various means. Most of the work has been published. Some has been submitted for publication. The structure of this thesis is as follows. In Chapter 1, I present the theory of manipulation of a nanomagnet by rotating ac fields whose frequency is time dependent. Theory has been developed that maps the problem onto Landau-Zener problem. For the linear frequency sweep the switching phase diagrams are obtained on the amplitude of the ac field and the frequency sweep rate. Switching conditions have been obtained numerically and analytically. For the nonlinear frequency sweep, the optimal time dependence of the frequency is obtained analytically with account of damping that gives the fastest controllable switching of the magnetization. In Chapter 2, interaction between a nanomagnet and a Josephson junction has been studied. The I-V curve of the Josephson junction in the proximity of a nanomagnet shows Shapiro-like steps due to the ac field generated by the precessing magnetic moment. Possibility of switching of the magnetic moment by a time-linear voltage in the Josephson junction is demonstrated. Realization of the optimal switching is suggested that employs two perpendicular Josephson junctions with time-dependent voltage signals. The result is shown to be robust against voltage noises. Quantum-mechanical coupling between the nanomagnet considered as a two-level system and a Josephson junction has been studied and quantum oscillations of the populations of the spin states have been computed. In Chapter 3, the switching dynamics of a nanomagnet embedded in a torsional oscillator that serves as a conducting wire for a spin current has been investigated. Generalized Slonczewski's equation is derived. The coupling of the nanomagnet, the torsional oscillator and the spin current generates a number of interesting phenomena. The mechanically

    Computing the optimal geometric structure of manipulators is one of the most intricate problems in contemporary robot kinematics. Robotic manipulators are designed and built to perform certain predetermined tasks. There is a very close relationship between the structure of the manipulator and its kinematic performance. It is therefore important to incorporate such task requirements during the design and synthesis of the robotic manipulators. Such task requirements and performance constraints can be specified in terms of the required end-effector positions, orientations and velocities along the task trajectory. In this work, we present a comprehensive method to develop the optimal geometric structure (DH parameters) of a non-redundant six degree of freedom serial manipulator from task descriptions. In this work we define, develop and test a methodology to design optimal manipulator configurations based on task descriptions. This methodology is devised to investigate all possible manipulator configurations that can satisfy the task performance requirements under imposed joint constraints. Out of all the possible structures, the structures that can reach all the task points with the required orientations are selected. Next, these candidate structures are tested to see whether they can attain end-effector velocities in arbitrary directions within the user defined joint constraints, so that they can deliver the best kinematic performance. Additionally least power consuming configurations are also identified. PMID:26257946

    1993-03-01

    A robot manipulator is said to be kinematically redundant when it has more degrees of freedom than are necessary to accomplish a particular task. Useful control strategies are designed for kinematically redundant manipulators in order to enhance their performance. Following the impedance control approach, the problem of minimizing redundant manipulator collision impacts is addressed. The configuration control approach is used to reduce impulsive forces, while a simplified impedance control scheme is formulated to minimize rebound effects. A new Cartesian control strategy for redundant flexible-joint manipulators is proposed. The main idea in this hybrid scheme is to control not only the manipulator's end-effector but also its links, so as to achieve specified positions and velocities for the end-effector and the links. Finally, a new application of kinematically redundant manipulators is proposed: using redundancy resolution to compensate for joint flexibility. This redundancy resolution scheme is incorporated in a control strategy for redundant flexible-joint manipulators. The problem of possible algorithmic singularities is considered, and a scheme is suggested which makes the controller robust with respect to such singularities.

    1992-01-01

    Telerobot systems for advanced applications will require manipulators with redundant 'degrees of freedom' (DOF) that are capable of adapting manipulator configurations to avoid obstacles while achieving the user specified goal. Conventional methods for control of manipulators (based on solution of the inverse kinematics) cannot be easily extended to these situations. Fuzzy logic control offers a possible solution to these needs. A current research program at SRI developed a fuzzy logic controller for a redundant, 4 DOF, planar manipulator. The manipulator end point trajectory can be specified by either a computer program (robot mode) or by manual input (teleoperator). The approach used expresses end-point error and the location of manipulator joints as fuzzy variables. Joint motions are determined by a fuzzy rule set without requiring solution of the inverse kinematics. Additional rules for sensor data, obstacle avoidance and preferred manipulator configuration, e.g., 'righty' or 'lefty', are easily accommodated. The procedure used to generate the fuzzy rules can be extended to higher DOF systems.

    Mobile manipulation in many respects represents the next generation of robot applications. An important part of design of such systems is the integration of techniques for navigation, recognition, control, and planning to achieve a robust solution. To study this problem three different approaches to mobile manipulation have been designed and implemented. A prototypical application that requires navigation and manipulation has been chosen as a target for the systems. In this paper we present the basic design of the three systems and draw some general lessons on design and implementation.

    Carpal tunnel syndrome (CTS) is 1 of the most common peripheral nerve entrapment disorders. Osteopathic manipulative medicine can be invaluable in diagnosing and managing CTS. Combined with a patient's history and a standard physical examination, an osteopathic structural examination can facilitate localizing the nerve entrapment, diagnosing CTS, and monitoring the disease process. Osteopathic manipulative treatment is noninvasive and can be used to supplement traditional CTS treatment methods. The authors also review the relevant anatomy involving CTS and the clinical efficacy of osteopathic manipulative medicine in the management of this disorder.

    2016-06-01

    By analogy to the definition of the dynamically consistent Jacobian inverse for robotic manipulators, we have designed a dynamically consistent Jacobian inverse for mobile manipulators built of a non-holonomic mobile platform and a holonomic on-board manipulator. The endogenous configuration space approach has been exploited as a source of conceptual guidelines. The new inverse guarantees a decoupling of the motion in the operational space from the forces exerted in the endogenous configuration space and annihilated by the dual Jacobian inverse. A performance study of the new Jacobian inverse as a tool for motion planning is presented.

    An articulated flexible manipulator carried on a translational cart is maneuvered by an active controller to perform certain position control tasks. The nonlinear dynamics of the articulated flexible manipulator are derived and a transformation matrix is formulated to localize the nonlinearities in the inertia matrix. Then a feeback linearization scheme is introduced to linearize the dynamic equations for controller design. Through a pole placement technique, a robust controller design is obtained by properly assigning a set of closed-loop desired eigenvalues to meet performance requirements. Numerical simulations for the articulated flexible manipulators are given to demonstrate the feasibility and effectiveness of the proposed position control algorithms.

  15. Review of methods used by chiropractors to determine the site for applying manipulation

    PubMed Central

    2013-01-01

    Background With the development of increasing evidence for the use of manipulation in the management of musculoskeletal conditions, there is growing interest in identifying the appropriate indications for care. Recently, attempts have been made to develop clinical prediction rules, however the validity of these clinical prediction rules remains unclear and their impact on care delivery has yet to be established. The current study was designed to evaluate the literature on the validity and reliability of the more common methods used by doctors of chiropractic to inform the choice of the site at which to apply spinal manipulation. Methods Structured searches were conducted in Medline, PubMed, CINAHL and ICL, supported by hand searches of archives, to identify studies of the diagnostic reliability and validity of common methods used to identify the site of treatment application. To be included, studies were to present original data from studies of human subjects and be designed to address the region or location of care delivery. Only English language manuscripts from peer-reviewed journals were included. The quality of evidence was ranked using QUADAS for validity and QAREL for reliability, as appropriate. Data were extracted and synthesized, and were evaluated in terms of strength of evidence and the degree to which the evidence was favourable for clinical use of the method under investigation. Results A total of 2594 titles were screened from which 201 articles met all inclusion criteria. The spectrum of manuscript quality was quite broad, as was the degree to which the evidence favoured clinical application of the diagnostic methods reviewed. The most convincing favourable evidence was for methods which confirmed or provoked pain at a specific spinal segmental level or region. There was also high quality evidence supporting the use, with limitations, of static and motion palpation, and measures of leg length inequality. Evidence of mixed quality supported the use

    An optical image-driven light induced dielectrophoresis (DEP) apparatus and method are described which provide for the manipulation of particles or cells with a diameter on the order of 100 .mu.m or less. The apparatus is referred to as optoelectric tweezers (OET) and provides a number of advantages over conventional optical tweezers, in particular the ability to perform operations in parallel and over a large area without damage to living cells. The OET device generally comprises a planar liquid-filled structure having one or more portions which are photoconductive to convert incoming light to a change in the electric field pattern. The light patterns are dynamically generated to provide a number of manipulation structures that can manipulate single particles and cells or groups of particles/cells. The OET preferably includes a microscopic imaging means to provide feedback for the optical manipulation, such as detecting position and characteristics wherein the light patterns are modulated accordingly.

  17. Which Colles' fractures should be manipulated?

    Dixon, Sean; Allen, Patricia; Bannister, Gordon

    2005-01-01

    Ninety-two patients with displaced Colles' fractures were followed prospectively after manipulation under regional anaesthesia. Radiographs were taken before and after manipulation and after 3 months when a functional assessment was also made. A correlation was sought between outcome and radiological measurements. Final radial shortening of 3mm or more was associated with a significantly worse functional outcome after 3 months (P < 0.001). Where the initial radial shortening was 3 mm or more, the probability of malunion was 65% whereas with less than 3mm, the probability of malunion was 28% (P < 0.001). With 5 mm or more of radial shortening at presentation, the probability of malunion was 73% (P < 0.01). The decision to manipulate remains a matter of judgement but a high failure rate renders simple manipulation and plaster cast fixation a poor treatment option in fractures with 5mm or more of radial shortening at presentation.

  18. What is morally new in genetic manipulation?

    PubMed

    Keenan, J F

    1990-01-01

    The investigation into the specific moral issues of genetic manipulation requires us to determine exactly the new moral issues of genetic manipulation. But even that determination requires us to consider whether the context in which we live and the method of moral reflection which we use is adequate enough to address genetic manipulation. Given the liberalist context in which we live, this paper argues that an act-oriented ethics is inadequate and that only a virtue-oriented ethics enables us to recognize and resolve the new problems ahead of us in genetic manipulation. Moreover, those problems have a common root, that is, that through genetics we will be in danger of objectifying the human subject.

  19. Brachioradial pruritus and cervical spine manipulation.

    PubMed

    Tait, C P; Grigg, E; Quirk, C J

    1998-08-01

    Brachioradial pruritus (BRP) causes significant morbidity in the majority of patients for whom no effective treatment is found. Chronic ultraviolet radiation exposure has usually been cited as the cause, but nerve damage from cervical spine disease has also been implicated. We report on a small retrospective exploratory study, conducted by questionnaire, of a group of patients who were treated with a specific cervical spine manipulation. Ten of 14 patients reported resolution of symptoms following manipulative treatment. All six patients who had had previous cervical spine disease responded to manipulation, as did half the remaining eight patients who had no previous history of neck symptoms. Although patients with BRP, by definition, share similar symptoms, the aetiology is almost certainly multifactorial. Prospective studies looking for cervical spine disease, as well as assessment of this particular method of cervical spine manipulation as a treatment modality for BRP, should be considered.

    The need for a telerobotic vehicle with hazard sensing and integral manipulation capabilities has been identified for use in transportation accidents where nuclear weapons are involved. The Accident Response Mobile Manipulation System (ARMMS) platform has been developed to provide remote dexterous manipulation and hazard sensing for the Accident Response Group (ARG) at Sandia National Laboratories. The ARMMS' mobility platform is a military HMMWV [High Mobility Multipurpose Wheeled Vehicle] that is teleoperated over RF or Fiber Optic communication channels. ARMMS is equipped with two high strength Schilling Titan II manipulators and a suite of hazardous gas and radiation sensors. Recently, a modular telerobotic control architecture call SMART (Sandia Modular Architecture for Robotic and Teleoperation) has been applied to ARMMS. SMART enables input devices and many system behaviors to be rapidly configured in the field for specific mission needs. This paper summarizes current SMART developments applied to ARMMS.

  5. Hybrid Image-Plane/Stereo Manipulation

    NASA Technical Reports Server (NTRS)

    Baumgartner, Eric; Robinson, Matthew

    2004-01-01

    Hybrid Image-Plane/Stereo (HIPS) manipulation is a method of processing image data, and of controlling a robotic manipulator arm in response to the data, that enables the manipulator arm to place an end-effector (an instrument or tool) precisely with respect to a target (see figure). Unlike other stereoscopic machine-vision-based methods of controlling robots, this method is robust in the face of calibration errors and changes in calibration during operation. In this method, a stereoscopic pair of cameras on the robot first acquires images of the manipulator at a set of predefined poses. The image data are processed to obtain image-plane coordinates of known visible features of the end-effector. Next, there is computed an initial calibration in the form of a mapping between (1) the image-plane coordinates and (2) the nominal three-dimensional coordinates of the noted end-effector features in a reference frame fixed to the main robot body at the base of the manipulator. The nominal three-dimensional coordinates are obtained by use of the nominal forward kinematics of the manipulator arm that is, calculated by use of the currently measured manipulator joint angles and previously measured lengths of manipulator arm segments under the assumption that the arm segments are rigid, that the arm lengths are constant, and that there is no backlash. It is understood from the outset that these nominal three-dimensional coordinates are likely to contain possibly significant calibration errors, but the effects of the errors are progressively reduced, as described next. As the end-effector is moved toward the target, the calibration is updated repeatedly by use of data from newly acquired images of the end-effector and of the corresponding nominal coordinates in the manipulator reference frame. By use of the updated calibration, the coordinates of the target are computed in manipulator-reference-frame coordinates and then used to the necessary manipulator joint angles to position

  7. Ecological consequences of manipulative parasites: chapter 9

    Lafferty, Kevin D.; Kuris, A. M.

    2012-01-01

    Parasitic "puppet masters", with their twisted, self-serving life history strategies and impressive evolutionary takeovers of host minds, capture the imagination of listeners—even those that might not normally fi nd the topic of parasitism appealing (which includes most everyone). A favorite anecdote concerns the trematode Leucochloridium paradoxum migrating to the eyestalks of its intermediate host snail and pulsating its colored body, presumably to attract the predatory birds that are the final hosts for the worm. Identifying a parasite as “manipulative” infers that a change in host behavior or appearance is a direct consequence of the parasite’s adaptive actions that, on average, will increase the fi tness of the parasite. The list of parasites that manipulate their hosts is long and growing. Holmes and Bethel (1972) presented the earliest comprehensive review and brought the subject to mainstream ecologists. Over two decades ago, Andy Dobson (1988) listed seven cestodes, seven trematodes, ten acanthocephalans, and three nematodes that manipulated host behavior. Fifteen years later, Janice Moore (2002) filled a book with examples. The five infectious trophic strategies, typical parasites (macroparasites), pathogens, trophically transmitted parasites, parasitic castrators, and parasitoids (Kuris and Lafferty 2000; Lafferty and Kuris 2002, 2009) can modify host behavior, but the likelihood that a parasite manipulates behavior differs among strategies. The most studied infectious agents, non-trophically transmitted pathogens and macroparasites, have enormous public health, veterinary, and wildlife disease importance, yet few manipulate host behavior. The beststudied manipulative infectious agents are trophically transmitted parasites in their prey intermediate hosts. Parasitoids and parasitic castrators can also manipulate host behavior, but for different purposes and with different implications. Several studies of manipulative parasites conclude with

The well known concepts of force and velocity manipulability ellipsoids for a single robot are formally extended and the contributions of the two single robots to the cooperative system ellipsoids are illustrated. Duality properties are discussed. A practical case study is developed.

    2008-04-01

    As mobile robots continue to gain acceptance across a variety of applications within the defense and civilian markets, the number of tasks that these robot platforms are expected to accomplish are expanding. Robot operators are asked to do more with the same platforms - from EOD missions to reconnaissance and inspection operations. Due to the fact that a majority of missions are dangerous in nature, it is critical that users are able to make remote adjustments to the systems to ensure that they are kept out of harm's way. An efficient way to expand the capabilities of existing robot platforms, improve the efficiency of robot missions, and to ultimately improve the operator's safety is to integrate JAUS-enabled Intelligent Modular Manipulation payloads. Intelligent Modular Manipulation payloads include both simple and dexterous manipulator arms with plug-and-play end-effector tools that can be changed based on the specific mission. End-effectors that can be swapped down-range provide an added benefit of decreased time-on-target. The intelligence in these systems comes from semi-autonomous mobile manipulation actions that enable the robot operator to perform manipulation task with the touch of a button on the OCU. RE2 is supporting Unmanned Systems Interoperability by utilizing the JAUS standard as the messaging protocol for all of its manipulation systems. Therefore, they can be easily adapted and integrated onto existing JAUS-enabled robot platforms.

    An anticipated goal of Mars surface exploration missions will be to survey and sample surface rock formations which appear scientifically interesting. In such a mission, a planetary rover would navigate close to a selected sampling site and the remote operator would use a manipulator mounted on the rover to perform a sampling operation. Techniques for accomplishing the necessary manipulation for the sampling components of such a mission have been developed and are presented. We discuss the implementation of a system for controlling a seven (7) degree of freedom Puma manipulator, equipped with a special rock gripper mounted on a planetary rover prototype, intended for the purpose of performing the sampling operation. Control is achieved by remote teleoperation. This paper discusses the real-time force control and supervisory control aspects of the rover manipulation system. Integration of the Puma manipulator with the existing distributed computer architecture is also discussed. The work described is a contribution toward achieving the coordinated manipulation and mobility necessary for a Mars sample acquisition and return scenario.

  12. Direct manipulation of virtual objects

    NASA Astrophysics Data System (ADS)

    Nguyen, Long K.

    Interacting with a Virtual Environment (VE) generally requires the user to correctly perceive the relative position and orientation of virtual objects. For applications requiring interaction in personal space, the user may also need to accurately judge the position of the virtual object relative to that of a real object, for example, a virtual button and the user's real hand. This is difficult since VEs generally only provide a subset of the cues experienced in the real world. Complicating matters further, VEs presented by currently available visual displays may be inaccurate or distorted due to technological limitations. Fundamental physiological and psychological aspects of vision as they pertain to the task of object manipulation were thoroughly reviewed. Other sensory modalities -- proprioception, haptics, and audition -- and their cross-interactions with each other and with vision are briefly discussed. Visual display technologies, the primary component of any VE, were canvassed and compared. Current applications and research were gathered and categorized by different VE types and object interaction techniques. While object interaction research abounds in the literature, pockets of research gaps remain. Direct, dexterous, manual interaction with virtual objects in Mixed Reality (MR), where the real, seen hand accurately and effectively interacts with virtual objects, has not yet been fully quantified. An experimental test bed was designed to provide the highest accuracy attainable for salient visual cues in personal space. Optical alignment and user calibration were carefully performed. The test bed accommodated the full continuum of VE types and sensory modalities for comprehensive comparison studies. Experimental designs included two sets, each measuring depth perception and object interaction. The first set addressed the extreme end points of the Reality-Virtuality (R-V) continuum -- Immersive Virtual Environment (IVE) and Reality Environment (RE). This

    All research results about flexible manipulator control were integrated to show a control scenario of a bracing manipulator. First, dynamic analysis of a flexible manipulator was done for modeling. Second, from the dynamic model, the inverse dynamic equation was derived, and the time domain inverse dynamic method was proposed for the calculation of the feedforward torque and the desired flexible coordinate trajectories. Third, a tracking controller was designed by combining the inverse dynamic feedforward control with the joint feedback control. The control scheme was applied to the tip position control of a single link flexible manipulator for zero and non-zero initial condition cases. Finally, the contact control scheme was added to the position tracking control. A control scenario of a bracing manipulator is provided and evaluated through simulation and experiment on a single link flexible manipulator.

    2014-01-01

    Background: The effects of cancer and associated treatments have a considerable impact on the well-being and quality of life of pediatric oncology patients. To support children and their families, complementary and alternative medicines are seen by nurses and doctors as practical to integrate to the services offered by hospitals. Objective: The purpose of this paper is to examine if the practice of complementary and alternative medicine, specifically spiritual care and treatments based on body manipulation, is likely to improve the health and well-being of children suffering from cancer. Method: This objective is achieved through a systematic review of the literature. The level of evidence associated with each practice of complementary and alternative medicine was assessed according to the methodological design used by the studies reviewed. Results and Conclusion: Studies reviewed are of a methodological quality that could be described as fair due to the small sample size of patients and the existence of a number of biases in the conduct and analysis of these studies. However, results obtained are consistent from one study to another, allowing us to make certain recommendations. It is thus advisable to consider the introduction of hypnotherapy in pediatric oncology services. Based on the data collected, it is the complementary and alternative medicine with the most evidence in favor of effectiveness of the well-being of pediatric oncology patients, especially during painful procedures. It is also recommended to use art therapy and music therapy. Conversely, too little evidence is present to be able to recommend the use of acupuncture, chiropractic or osteopathy. PMID:24576371

  17. Precision manipulation with a dextrous robot hand

    NASA Astrophysics Data System (ADS)

    Michelman, Paul

    1994-01-01

    In this thesis, we discuss a framework for describing and synthesizing precision manipulation tasks with a robot hand. Precision manipulations are those in which the motions of grasped objects are caused by finger motions alone (as distinct from arm or wrist motion). Experiments demonstrating the capabilities of the Utah-MIT hand are presented. This work begins by examining current research on biological motor control to raise a number of questions. For example, is the control centralized and organized by a central processor? Or is the control distributed throughout the nervous system? Motor control research on manipulation has focused on developing classifications of hand motions, concentrating solely on finger motions, while neglecting grasp stability and interaction forces that occur in manipulation. In addition, these taxonomies have not been explicitly functional. This thesis defines and analyzes a basic set of manipulation strategies that includes both position and force trajectories. The fundamental purposes of the manipulations are: (1) rectilinear and rotational motion of grasped objects of different geometries; and (2) the application of forces and moments against the environment by the grasped objects. First, task partitioning is described to allocate the fingers their roles in the task. Second, for each strategy, the mechanics and workspace of the tasks are analyzed geometrically to determine the gross finger trajectories required to achieve the tasks. Techniques illustrating the combination of simple manipulations into complex, multiple degree-of-freedom tasks are presented. There is a discussion of several tasks that use multiple elementary strategies. The tasks described are removing the top of a childproof medicine bottle, putting the top back on, rotating and regrasping a block and a cylinder within the grasp. Finally, experimental results are presented. The experimental setup at Columbia University's Center for Research in Intelligent Systems and

    2011-10-01

    Manipulation is an important issue for both developed and emerging stock markets. For the study of manipulation, it is critical to analyze investor behavior in the stock market. In this paper, an analysis of the full transaction records of over a hundred stocks in a one-year period is conducted. For each stock, a trading network is constructed to characterize the relations among its investors. In trading networks, nodes represent investors and a directed link connects a stock seller to a buyer with the total trade size as the weight of the link, and the node strength is the sum of all edge weights of a node. For all these trading networks, we find that the node degree and node strength both have tails following a power-law distribution. Compared with non-manipulated stocks, manipulated stocks have a high lower bound of the power-law tail, a high average degree of the trading network and a low correlation between the price return and the seller-buyer ratio. These findings may help us to detect manipulated stocks.

  19. Better with Byzantine: Manipulation-Optimal Mechanisms

    NASA Astrophysics Data System (ADS)

    Othman, Abraham; Sandholm, Tuomas

    A mechanism is manipulable if it is in some agents’ best interest to misrepresent their private information. The revelation principle establishes that, roughly, anything that can be accomplished by a manipulable mechanism can also be accomplished with a truthful mechanism. Yet agents often fail to play their optimal manipulations due to computational limitations or various flavors of incompetence and cognitive biases. Thus, manipulable mechanisms in particular should anticipate byzantine play. We study manipulation-optimal mechanisms: mechanisms that are undominated by truthful mechanisms when agents act fully rationally, and do better than any truthful mechanism if any agent fails to act rationally in any way. This enables the mechanism designer to do better than the revelation principle would suggest, and obviates the need to predict byzantine agents’ irrational behavior. We prove a host of possibility and impossibility results for the concept which have the impression of broadly limiting possibility. These results are largely in line with the revelation principle, although the considerations are more subtle and the impossibility not universal.

    A recent study reports partner manipulation for an interaction that was considered a reward-for-defence mutualism. Secretions of lycaenid caterpillars altered ant locomotion and aggressiveness, likely by manipulating dopaminergic signalling. This study opens the question whether such manipulation is common and whether manipulation necessarily characterises an interaction as parasitism.

  3. Ultrasonic resonator for manipulation of bacteria

    Schwarz, T.; Dual, J.

    2012-05-01

    Ultrasonic manipulation is a contactless and gentle method to manipulate a large number of particles. The method presented here exploits the advantage to simultaneously move bacteria away from a surface by means of acoustic radiation forces. The device for the manipulation consists of five layers (transducer, epoxy adhesive layer, carrier, fluid, reflector), stacked like a conventional planar resonator. The resonator behavior was simulated using the transfer matrix method (TMM). Validation of the model was realized with admittance measurements performed over a wide frequency range (100 kHz - 16 MHz). The TMM-model was used to optimize frequency, layer thickness and material of the resonator in order to find a combination with a high force potential gradient pointing away from the reflector surface into the fluid. The resonator has been experimentally tested with polystyrene particles (1 μm in diameter) which revealed a good matching with the TMM-model. First preliminary tests with Salmonella Thyphimurium have been done.

  4. Design of multivariable controllers for robot manipulators

    Seraji, H.

    1986-01-01

    The paper presents a simple method for the design of linear multivariable controllers for multi-link robot manipulators. The control scheme consists of multivariable feedforward and feedback controllers. The feedforward controller is the minimal inverse of the linearized model of robot dynamics and contains only proportional-double-derivative (PD2) terms. This controller ensures that the manipulator joint angles track any reference trajectories. The feedback controller is of proportional-integral-derivative (PID) type and achieves pole placement. This controller reduces any initial tracking error to zero as desired and also ensures that robust steady-state tracking of step-plus-exponential trajectories is achieved by the joint angles. The two controllers are independent of each other and are designed separately based on the linearized robot model and then integrated in the overall control scheme. The proposed scheme is simple and can be implemented for real-time control of robot manipulators.

  5. Force reflecting hand controller for manipulator teleoperation

    Bryfogle, Mark D.

    1991-01-01

    A force reflecting hand controller based upon a six degree of freedom fully parallel mechanism, often termed a Stewart Platform, has been designed, constructed, and tested as an integrated system with a slave robot manipulator test bed. A force reflecting hand controller comprises a kinesthetic device capable of transmitting position and orientation commands to a slave robot manipulator while simultaneously representing the environmental interaction forces of the slave manipulator back to the operator through actuators driving the hand controller mechanism. The Stewart Platform was chosen as a novel approach to improve force reflecting teleoperation because of its inherently high ratio of load generation capability to system mass content and the correspondingly high dynamic bandwidth. An additional novelty of the program was to implement closed loop force and torque control about the hand controller mechanism by equipping the handgrip with a six degree of freedom force and torque measuring cell. The mechanical, electrical, computer, and control systems are discussed and system tests are presented.

    1989-01-01

    Spirulina sp. as a bioregenerative photosynthetic and an edible alga for spacecraft crew in a CELSS, was characterized for the biomass yield in batch cultures, under various environmental conditions. The partitioning of the assimalitory products (proteins, carbohydrates, lipids) were manipulated by varying the environmental growth conditions. Experiments with Spirulina have shown that under stress conditions (i.e., high light 160 uE/sq m/s, temperature 38 C, nitrogen or phosphate limitation; 0.1 M sodium chloride) carbohydrates increased at the expense of proteins. In other experiments, where the growth media were sufficient in nutrients and incubated under optimum growth conditions, the total of the algal could be manipulated by growth conditions. These results support the feasibility of considering Spirulina as a subsystem in CELSS because of the ease with which its nutrient content can be manipulated.

    1988-01-01

    A habitable space station was proposed for low earth orbit, to be constructed from components which will be separately carried up from the earth and thereafter assembled. A suitable manipulating system having extraordinary manipulative capability is required. The invention is an erectable manipulator placement system for use on a space station and comprises an elongate, lattice-like boom having guide tracks attached thereto, a carriage-like assembly pivotally mounted on and extending from said dolly. The system further includes a turntable base pivotally interconnected with the proximal end of the boom and positioned either on a part of a transferring vehicle, or on another payload component being carried by the said transferring vehicle, or on the space station. Novelty resides in the use of a turntable base having a hinged boom with a dolly translatable therealong to carry the arm-like assembly, thus providing an additional 3 degrees of freedom to the arm.

    1975-01-01

    An analytical and experimental study was conducted to specify a video system for remote manipulation in space. An operator function analysis identified two basic characteristics, work volume and element relationship, which define four manipulation tasks chosen for examination. A visual function analysis developed a set of elemental scene parameters which grouped the visual dimensions into major areas of influence. Simulation testing was conducted with a four degree-of-freedom motion frame which allowed an operator to perform the manipulation tasks. Four video systems were included in the simulation testing: a black and white and a color monoscopic system, a stereoscopic system, and a black and white two-view system. A sequential experimental plan first provided an overall analysis of the effects of tasks, scene parameters, and video systems. This was followed by a detailed experimental examination of the critical dimensions identified in the first experiment. Results are discussed in terms of a recommended TV system.

    This paper describes the manipulator for live-line construction of high-voltage overhead power transmission lines (line voltage 6.6 kV) that is being jointly developed by Tokyo Electric Power and other companies. It describes this system's development concept, makeup, functions, and design, as well as operability tests using actual-scale transmission line poles. In this research, development began in 1984. As the first step, a prototype model of a ground-mounted twin-arm manipulator was trial-manufactured in 1985. As the second step, in 1988 a truck-mounted system was developed in which the twin-arm manipulator was mounted on a cherrypicker vehicle. As the third step, a practical system was developed based on these results.

  11. Cooperative control of multiple space manipulators

    NASA Astrophysics Data System (ADS)

    Nahon, M.; Angeles, J.

    The control of multi-armed robotic systems is inherently more complex than that of single-arm systems. Whereas a single manipulator can be controlled purely through positions or velocities, multiple manipulators handling a common payload must also be controlled in terms of forces. In this paper, the problem of finding force setpoints for the controller is formulated as a constrained optimization problem where the constraints are provided by the dynamics equations and the actuator capabilities. A number of potential objective functions which may be minimized are reviewed including the internal force, a norm of the vector of actuator torques and power losses in the system. These are then compared for a task in which the Special Purpose Dextrous Manipulator (SPDM) moves a payload in the absence of gravity. It is concluded that the actuator torque criterion appears to offer the worst compromise in performance, while the minimum internal force and minimum power loss criteria each have their advantages.

    Microfluidics, especially droplet microfluidics, attracts more and more researchers from diverse fields, because it requires fewer materials and less time, produces less waste and has the potential of highly integrated and computer-controlled reaction processes for chemistry and biology. Electrorheological fluid, especially giant electrorheological fluid (GERF), which is considered as a kind of smart material, has been applied to the microfluidic systems to achieve active and precise control of fluid by electrical signal. In this review article, we will introduce recent results of microfluidic droplet manipulation, GERF and some pertinent achievements by introducing GERF into microfluidic system: digital generation, manipulation of "smart droplets" and droplet manipulation by GERF. Once it is combined with real-time detection, integrated chip with multiple functions can be realized.

    2004-01-01

    Acoustic liquid manipulation is a family of techniques that employ the nonlinear acoustic effects of acoustic radiation pressure and acoustic streaming to manipulate the behavior of liquids. Researchers at the NASA Glenn Research Center are exploring new methods of manipulating liquids for a variety of space applications, and we have found that acoustic techniques may also be used in the normal Earth gravity environment to enhance the performance of existing fluid processes. Working in concert with the NASA Commercial Technology Office, the Great Lakes Industrial Technology Center, and Alchemitron Corporation (Elgin, IL), researchers at Glenn have applied nonlinear acoustic principles to industrial applications. Collaborating with Alchemitron Corporation, we have adapted the devices to create acoustic streaming in a conventional electroplating process.

    Schmitz, D.; Kanade, T.

    1987-01-01

    Using manipulators with a fixed configuration for specific tasks is appropriate when the task requirements are known beforehand. However, in less predictable situations, such as an outdoor construction site or aboard a space station, a manipulator system requires a wide range of capabilities, probably beyond the limitations of a single, fixed-configuration manipulator. To fulfill this need, researchers have been working on a Reconfigurable Modular Manipulator System (RMMS). Researchers have designed and are constructing a prototype RMMS. The prototype currently consists of two joint modules and four link modules. The joints utilize a conventional harmonic drive and torque motor actuator, with a small servo amplifier included in the assembly. A brushless resolver is used to sense the joint position and velocity. For coupling the modules together, a standard electrical connector and V-band clamps for mechanical connection are used, although more sophisticated designs are under way for future versions. The joint design yields an output torque to 50 ft-lbf at joint speeds up to 1 radian/second. The resolver and associated electronics have resolutions of 0.0001 radians, and absolute accuracies of plus or minus 0.001 radians. Manipulators configured from these prototype modules will have maximum reaches in the 0.5 to 2 meter range. The real-time RMMS controller consists of a Motorola 68020 single-board computer which will perform real time servo control and path planning of the manipulator. This single board computer communicates via shared memory with a SUN3 workstation, which serves as a software development system and robot programming environment. Researchers have designed a bus communication network to provide multiplexed communication between the joint modules and the computer controller. The bus supports identification of modules, sensing of joint states, and commands to the joint actuator. This network has sufficient bandwidth to allow servo sampling rates in

    We report a holographic assembler workstation for optical trapping and micro-manipulation. The workstation is based on a titanium sapphire laser, making it particularly suited for biomaterials and incorporates a choice of user interfaces for different applications. The system is designed around a commercial inverted microscope and is configured such that it can be easily used by the non-specialist.

    Techniques for improving the performance of robotic-manipulator path-control systems comprising independent SISO feedback controllers for each joint are discussed and illustrated with block diagrams, reviewing the results of recent analytical investigations. Topics examined include the servo design for a single link, the equations of motion for manipulators, SISO servo design for multiple links, inverse methods, pole placement with compensation of the gravity terms, linear state-feedback control based on the perturbation equations, and adaptive control methods. Consideration is given to variable-structure systems, suboptimal controllers, and the optimal-design-strategy approach.

    2016-07-01

    Magnetic skyrmion holds promise as information carriers in the next-generation memory and logic devices, owing to the topological stability, small size and extremely low current needed to drive it. One of the most potential applications of skyrmion is to design racetrack memory (RM), named Sk-RM, instead of utilizing domain wall (DW). However, current studies face some key design challenges, e.g., skyrmion manipulation, data representation and synchronization etc. To address these challenges, we propose here a complementary Sk-RM structure with voltage manipulation. Functionality and performance of the proposed design are investigated with micromagnetic simulations.

    1990-01-01

    If robots must function in unstructured environments, they must also possess the ability to acquire information and construct appropriate models of the unknown environment. This paper addresses the automatic generation of kinematic models of unknown objects with movable parts in the environment. If the relative motion between moving parts must be observed and characterized, vision alone cannot suffice. An approach in which manipulation is used with vision for sensing is better suited to the task of determining kinematic properties. In this paper, algorithms for constructing models of unknown mechanical assemblies and characterizing the relative motion are developed. Results of a simulation are described to demonstrate the role of manipulation in such an endeavor.

    1980-01-01

    A new conceptually simple approach to controlling compliant motions of a robot manipulator is presented. The 'hybrid' technique described combines force and torque information with positional data to satisfy simultaneous position and force trajectory constraints specified in a convenient task related coordinate system. Analysis, simulation, and experiments are used to evaluate the controller's ability to execute trajectories using feedback from a force sensing wrist and from position sensors found in the manipulator joints. The results show that the method achieves stable, accurate control of force and position trajectories for a variety of test conditions.
