    Spinal cord injury is a rare complication of chiropractic treatment. This case report describes a 50-year-old man who developed neurological symptoms a few hours after manipulation (high velocity low amplitude [HVLA] technique) of the cervical spine. Magnetic resonance (MR) imaging of the cervical spine revealed intramedullary high signal at the C2/3 level of the right side of the cervical cord on the T2-weighted images. The potential mechanism of injury and causes of the radiological appearance are discussed.

    Background: Multivessel cervical dissection with cortical sparing is exceptional in clinical practice. Case presentation: A 55-year-old man presented with acute-onset neck pain with associated sudden onset right-sided hemiparesis and dysphasia after chiropractic manipulation for chronic neck pain. Results and Discussion: Magnetic resonance imaging revealed bilateral internal carotid artery dissection and left extracranial vertebral artery dissection with bilateral anterior cerebral artery territory infarctions and large cortical-sparing left middle cerebral artery infarction. This suggests the presence of functionally patent and interconnecting leptomeningeal anastomoses between cerebral arteries, which may provide sufficient blood flow to salvage penumbral regions when a supplying artery is occluded. Conclusion: Chiropractic cervical manipulation can result in catastrophic vascular lesions preventable if these practices are limited to highly specialized personnel under very specific situations.

    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

    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

    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.

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

    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

  7. Chiropractic spinal manipulative therapy for migraine: a study protocol of a single-blinded placebo-controlled randomised clinical trial

    2015-01-01

    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.

    Chaibi, Aleksander; Tuchin, Peter J.

    2011-01-01

    Objective The purpose of this article is to present a case study of chiropractic spinal manipulative treatment (CSMT) using the Gonstead method for a patient with migraines. Clinical Features The patient was a 52-year-old married woman with a long-term history of chronic migraines, which included nausea, vomiting, and photophobia. The patient had endometriosis, but did not relate the migraines to her menstrual cycles. She also reported not using medication for her migraines due to previous drug-related issues. The average frequency of episodes before treatment was 1 per month, and her migraines often included an aura. The pain was moderate, was located on the right side, was pulsating, and lasted for approximately 15 hours. The numeric pain scale for an average episode was 8 out of a possible 10. The aura involved nausea, photophobia, and visual disturbances including black dots in the visual field lasting for approximately 10 minutes. Intervention and Outcome The patient reported all episodes being eliminated following CSMT. At 6-month follow-up, the patient had not had a single migraine episode in this period. The patient was certain that there had been no other lifestyle changes that could have contributed to her improvement. Conclusion This case adds to previous research suggesting that some migraine patients may respond favorably to CSMT. The case also provides information on the Gonstead method. A case study does not represent significant scientific evidence in context with other studies conducted; this study suggests that a trial of CSMT using the Gonstead methods could be considered for chronic, nonresponsive migraines.

Conclusion This patient with persistent headache responded favorably to a course of chiropractic and adjunctive care. PMID:24396331

  13. 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. PMID:26806448

    PubMed

    Klein, P

    1998-09-01

    Osteopathy and chiropractic represent two challenging domains with a specific degree of multiplicity and complexity. This makes a complete appraisal difficult and impossible to appreciate in one single analysis. These disciplines exist since more than one century. An hermeneutic approach permits to understand their genesis but indicates also the nonsense of trying to transfer and apply earliest principles nowadays. It seems that most, but not all, practicing clinicians take into account recent developments in physiology, biomechanics and pathophysiology. Clinical studies and especially their meta-analyses on base of precise criteria permit to clarify the indications, therapeutic efficiency as well as socio-economic advantages. The meta-analyses point also at the poor quality of most clinical studies even if in the last years an improvement can be noted. Fundamental studies exist in both domains revealing interesting information that have permitted to reject several preconceived ideas and to clarifs others. Research topics as the morphology of the intervertebral disk before and after application of a manipulative technique are discussed. Results of experimental determination of global and segmental amplitudes in the cervical and in the lumbar spine during a manipulation in healthy subjects are reported. Finally the necessity but also the difficulties inherent to research studies in osteopathy and in chiropractic will be discussed. PMID:9805958

    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

    Charlton, Keith H

    2005-01-01

    Background There is little homogeneity of opinion in the chiropractic profession about its essence and identity. Matters compromising the establishment of a coherent identity include the issue of vertebral subluxation, philosophy, mercantilism, poverty of qualifications in some chiropractic college faculty, and lack of intellectual productivity in some chiropractic college faculty. Discussion The Chiropractic profession has mislabeled rhetoric, supposition and cant as philosophy, whilst showing sparse evidence for the existence of more than a few chiropractors writing in philosophy as a discipline. There is no evidence for "Chiropractic Philosophy". I propose, however, that a better use of the discipline of philosophy can be of great use to the Chiropractic profession. Various thinkers throughout the ages have written about deduction, induction and falsificationism as methods to discover more reliably the nature of things in the world about us. Each method has strengths and frailties, but some of the latter are insurmountable for our purposes. Summary Using a contrivance of that method which seems most suited, sui generis, for the purpose, I propose a Chiropracticness Test as a tool to assist the search for essence and identity in Chiropractic.

  1. 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.

  4. Recognition of Spontaneous Vertebral Artery Dissection Preempting Spinal Manipulative Therapy: A Patient Presenting With Neck Pain and Headache for Chiropractic Care

    PubMed Central

    Mattox, Ross; Smith, Linda W.; Kettner, Norman W.

    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.

    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

    1999-05-30

    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. PMID:10394283

    2016-01-01

    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.

    2011-01-01

    Purpose: The goal of the present study was to quantify the high-velocity, low-amplitude spinal manipulation biomechanical parameters in two cohorts of students from different teaching institutions. The first cohort of students was taught chiropractic techniques in a patient–doctor positioning practice setting, while the second cohort of students was taught in a “complete practice” manipulation setting, thus performing spinal manipulation skills on fellow student colleagues. It was hypothesized that the students exposed to complete practice would perform the standardized spinal manipulation with better biomechanical parameters. Methods: Participants (n = 88) were students enrolled in two distinct chiropractic programs. Thoracic spine manipulation skills were assessed using an instrumented manikin, which allowed the measurement of applied force. Dependent variables included peak force, time to peak force, rate of force production, peak force variability, and global coordination. Results: The results revealed that students exposed to complete practice demonstrated lower time to peak force values, higher peak force, and a steeper rate of force production compared with students in the patient–doctor positioning scenario. A significant group by gender interaction was also noted for the time to peak force and rate of force production variables. Conclusion: The results of the present study confirm the importance of chiropractic technique curriculum and perhaps gender in spinal manipulation skill learning. It also stresses the importance of integrating spinal manipulation skills practice early in training to maximize the number and the quality of significant learner–instructor interactions.

  14. Chiropractic and geriatrics: a review of the training, role, and scope of chiropractic in caring for aging patients.

    Killinger, Lisa Zaynab

    2004-05-01

    Chiropractors may be well-positioned to play an important role in health promotion, injury and disease prevention, and on geriatric care teams, due to their practice style and holistic philosophy. The bottom line in aging care is that someone in the health-care world must provide health promotion and preventive services to older patients before the wave of aged patients profoundly overwhelms our health-care system. Chiropractic services are safe and relatively low-cost, and patient satisfaction with them is very high. In the managed-care environment, time pressures on allopathic providers may preclude them from spending sufficient time discussing health promotion and illness prevention with their patients. Chiropractic, when paid for out-of-pocket, is not as affected by these extreme pressures. With the hands-on nature of chiropractic care, a strong doctor-patient relationship is forged in which health and lifestyle recommendations may be comfortably and effectively discussed. Relative to musculoskeletal care in elderly patients, chiropractic adjustments (spinal manipulative therapy) are recommended by the Agency for Health Care Policy and Research for the care of acute low back pain, and the American Geriatric Society Panel Guidelines for the Management of Chronic Pain state that non-pharmaceutical interventions such as chiropractic may be appropriate. Most geriatric health-care providers have a limited number of options to offer patients with these complaints. Various lower-force chiropractic techniques are available as safe alternatives to drugs and surgery for musculoskeletal complaints in the older patient. Due to the prevalence of these conditions in older patients, and the success of chiropractic in caring for these patients, interdisciplinary geriatric health care teams should include the doctor of chiropractic. Chiropractors, well trained in health assessment, diagnosis, radiographic studies, health promotion, and illness prevention, are well-positioned to

    Introduction: The reliability and validity of many evaluation tools leading to clinical decision-making for spinal manipulation are varied. We surveyed senior students and DC employees at one chiropractic college regarding 1) which analysis tools should be used and 2) factors that influence their choices. Methods: The survey queried which tools should be used on a routine patient encounter. Clinical evaluation tools included palpation, skin temperature analysis, leg length analysis, and radiographs. Results: Surveys were collected from 58 doctors of chiropractic (DCs) and 74 students. Respondents from both groups reported to most commonly use static palpation, followed by motion palpation and leg length analysis. DC respondents ranked evidence and personal experience high for rationale; student respondents frequently chose patient preference. Conclusion: DC and student respondents reported use of clinical evaluation tools consistently. However, some variations in rationale were noted. It is important for educators to provide a balanced presentation of the strengths and limitations of clinical analysis procedures to support the development of well-justified evidence-based clinical decision-making skills.

    2010-01-01

    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

    2015-06-01

    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.

    2006-01-01

    Background: Admissions departments at chiropractic colleges across the United States are under continual pressure to recruit students. The underrepresented minority populations in the United States are potential markets for chiropractic patients, students, and doctors. Objective: To assess the current diversity recruiting practices of the chiropractic colleges. Methods: Directors of admissions of the chiropractic colleges were polled to identify recruiting programs and their success. Results: Sixteen of the 17 colleges were polled. Nine of the respondents had no program for targeted underserved populations and seven did have such a program. Five colleges employed several methods to work with universities to recruit underserved populations. Other strategies included outreach via student groups and alumni recruiters. Conclusion: Programs to attract minority students can be created and infrastructure can be provided but they are nearly useless without role models. Encouraging alumni participation to raise awareness of chiropractic in minority communities may be a step toward a profession more reflective of America’s population. PMID:18483633

    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

    2015-01-01

    Objective The purpose of this case report is to describe the chiropractic management of a child with abnormal fixation of one eye and torticollis. Clinical Features A mother presented with a concern regarding her 23-month-old son who had a history of torticollis and an abnormal fixation of the right eye. She noticed the head tilt when he was about 7 months old and abnormal alignment of the right eye when the boy was 18 months old. At 15 months when he took his first steps, his head tilt became worse. At 21 months old, a neurological and orthopedic examination at the regional university children`s hospital ruled out presence of a tumor of the cervical spine or posterior fossa. The orthopedist sent the baby for chiropractic evaluation and treatment. Chiropractic exam found decreased active and passive range of motion in the cervical spine and no evidence of mass or contracture of the sternocleidomastoid muscle. Segmental palpation showed a decreased joint play and pain reaction at level C1/C2 on the right. Intervention and Outcome The chiropractic treatment consisted of spinal manipulative therapy of the cervical spine in addition to massage and stretching of the neck muscles. Within a period of 4 weeks (3 chiropractic treatments) the torticollis was nearly resolved and the abnormal fixation of the right eye was no longer apparent. No relapse of the symptomatology was observed at a follow-up consultation at 26 months. Conclusion The patient responded favorably to chiropractic care, showing a possible mechanical spinal cause for his torticollis and for the secondarily developed abnormal fixation of the right eye.

    Objective Work-related upper limb disorder (WRULD) encompasses a broad array of occupational upper limb injuries, the most common being carpal tunnel syndrome (CTS). Carpal tunnel syndrome occasionally presents with concomitant ganglion cysts. The purpose of this case report is to describe the chiropractic management of a patient with bilateral WRULD complicated by ganglion cysts. Clinical Features The patient was diagnosed previously with bilateral CTS and presented with common CTS symptoms that were nonresponsive to several previous courses of care. Magnetic resonance imaging revealed bilateral ganglion cysts, and electrodiagnostic studies found left CTS and bilateral radial neuralgia. Right limb findings appeared more consistent with nonspecific arm pain. Intervention and Outcome Chiropractic manipulative therapy, soft-tissue approaches, and physiotherapy modalities were applied to the arms and wrists over a 3-month period. Home care included exercises using elastic tubing and a gyroscopic handheld device. Chiropractic manipulative therapy and other conservative approaches resulted in subjective improvements of decreased hand paresthesias and muscle weakness and objective improvements in range of motion and neurologic deficits. Although the patient's symptoms and function improved, she remained with a level of permanent impairment. Conclusion This case demonstrates successful chiropractic management of a patient with WRULD complicated by ganglion cysts. Further larger-scale studies are recommended to determine if chiropractic management demonstrates positive outcomes for this condition. PMID:22014905

    2013-01-01

    Objective The purpose of this case series is to describe chiropractic care including spinal manipulation for 3 patients with postsurgical spine pain. Clinical features Three patients with postsurgical spine pain (1 cervical fusion, 1 lumbar discectomy, and 1 lumbar laminectomy) presented for chiropractic treatment at a major US medical center. Treatment included spinal manipulation and/or flexion-distraction mobilization based on patient response to joint loading strategies. Intervention and outcomes Two patients were treated with high-velocity, low-amplitude spinal manipulation; and 1 patient was treated with flexion-distraction mobilization. Treatment frequency and duration were 4 treatments over 4 weeks for case 1, 17 treatments over 7 years for case 2, and 5 treatments over 5 weeks for case 3. Subjective improvement was noted using numeric pain scores and functional changes; and upon completion, the patients reported being “satisfied” with their overall outcome. One episode of transient benign soreness was noted by 1 patient. No additional adverse events or effects were noted. Conclusion In these 3 cases, patients with postsurgical spine pain responded positively to chiropractic care. Spinal manipulation/mobilization was tolerated without significant adverse effects.

    Abstract Objective To describe a common musculoskeletal disorder from a chiropractic management prospective, subsequently to stimulate further research into the chiropractic therapeutic effects on such cases and to contribute to chiropractic literature. Clinical Features A 27-year-old, 76” male student often involved in athletic activities, had a sudden onset of continuous localized pain in the medial aspect of the mid and forefoot on the right side for 1-and-a half months. The onset of pain was related to an accidental injury while playing basketball. The pain worsened every time during and after playing basketball and other weight-bearing activities such as walking upstairs and is palliated with physical rest. He tried Biofreeze and ice application for several times immediately after the injuries which help to some extent to relieve pain and swelling, but he did not seek any other professional care. The condition had been improving slowly even before he came to the clinic although the patient described the pain as 5/10 on the Borg pain scale when he came to the clinic for the first time. The characteristic local findings were a mildly hyper-pronated right foot, mildly asymmetric soft-tissue and bony contours, tenderness, stiffness and decreased range of motion (ROM) at the first metatarsophalangel and adjacent joints on the medial aspect of the midfoot decreased fluid motions in the concerned joints on the chiropractic evaluation and some abnormal wearing in the shoes. Intervention and Outcome He was managed with chiropractic manipulation combined with other conservative measures. Range of motion (ROM), Borg Pain Scale and an orthopedic test (Morton's Test) were used as the outcome measures. The subject showed a favorable response to the conservative (chiropractic) care. Conclusion Although hallux rigidus is one of the most common musculoskeletal degenerative conditions, our conservative management received a favorable response but there has been little

    Objective The purpose of this case report is to describe chiropractic care of an adolescent with acute low back pain and incidental finding of spina bifida occulta managed with high-velocity low-amplitude manipulation. Clinical Features A 10-year-old boy was referred for chiropractic care by his pediatrician for the management of low back pain after a fall 3 days prior. Examination and medical records revealed the patient also had spina bifida occulta at the level of L5. Intervention and Outcome High-velocity low-amplitude treatment for lower back pain showed resolution of patient's pain after 6 visits. No adverse effects were reported. Conclusion An adolescent patient with lower back pain and incidental finding of spina bifida occulta improved with a course of care that included with high-velocity low-amplitude manipulation therapy.

    2012-01-01

    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 the clinical presentation and chiropractic management of Tietze syndrome. Clinical Features A 34-year-old woman presented with unexplained left-sided chest pain. Electrocardiogram and radiographs were taken at a medical emergency department to rule out cardiovascular and pulmonary causes, and pain medication did not relieve her pain. Physical examination showed tenderness on palpation and swelling of the second and third chondrosternal joints, as well as thoracic joint dysfunction. Heart and lung pathology was ruled out, and chondrosternal joint swelling was present, Tietze syndrome was diagnosed. Intervention and Outcome A treatment plan aimed at restoring normal thoracic and rib joint movement and decreasing inflammation of the chondrosternal joints resulted in lower pain levels. Treatment consisted of diversified high-velocity, low-amplitude chiropractic manipulation; activator technique; and cryotherapy. Conclusion Chiropractic management of Tietze syndrome was successful in reducing pain levels in this patient's case. PMID:22027210

    2010-01-01

    Purpose: This paper reviews the origins of the learned professions, the foundational concepts of professionalism, and the common elements within various healer's oaths. It then reveals the development of the Murdoch Chiropractic Graduate Pledge. Methods: A committee comprised of three Murdoch academics performed literature searches on the topic of professionalism and healer's oaths and utilized the Quaker consensus process to develop the Murdoch Chiropractic Graduate Pledge. Results: The committee in its deliberations utilized over 200 relevant papers and textbooks to formulate the Murdoch Chiropractic Graduate Pledge that was administered to the 2010 Murdoch School of Chiropractic and Sports Science graduates. The School of Chiropractic and Sports Science included professionalism as one of its strategic goals and began the process of curriculum review to align it with the goal of providing a curriculum that recognizes and emphasizes the development of professionalism. Conclusions: The reciting of a healer's oath such as the Hippocratic Oath is widely considered to be the first step in a new doctor's career. It is seen as the affirmation that a newly trained health care provider will use his or her newfound knowledge and skill exclusively for the benefit of mankind in an ethical manner. Born from the very meaning of the word profession, the tradition of recitation of a healer's oath is resurgent in health care. It is important for health care instructors to understand that the curriculum must be such that it contributes positively to the students' professional development. PMID:21048880

  11. 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

    A 30-year-old woman presented to an emergency department with sudden onset of transient loss of left peripheral vision. Owing to a history of migraine headaches, she was released with a diagnosis of ocular migraine. Two days later, she sought chiropractic care for the chief symptom of severe neck pain. The chiropractor suspected the possibility of vertebral artery dissection (VAD). No manipulation was performed; instead, MR angiography (MRA) of the neck was obtained, which revealed an acute left VAD with early thrombus formation. The patient was placed on aspirin therapy. Repeat MRA of the neck 3 months later revealed resolution of the thrombus, without progression to stroke. This case illustrates the importance for all healthcare providers who see patients with neck pain and headache to be attentive to the symptomatic presentation of possible VAD in progress.

    Background More than 100 years after its inception the chiropractic profession has failed to define itself in a way that is understandable, credible and scientifically coherent. This failure has prevented the profession from establishing its cultural authority over any specific domain of health care. Objective To present a model for the chiropractic profession to establish cultural authority and increase market share of the public seeking chiropractic care. Discussion The continued failure by the chiropractic profession to remedy this state of affairs will pose a distinct threat to the future viability of the profession. Three specific characteristics of the profession are identified as impediments to the creation of a credible definition of chiropractic: Departures from accepted standards of professional ethics; reliance upon obsolete principles of chiropractic philosophy; and the promotion of chiropractors as primary care providers. A chiropractic professional identity should be based on spinal care as the defining clinical purpose of chiropractic, chiropractic as an integrated part of the healthcare mainstream, the rigorous implementation of accepted standards of professional ethics, chiropractors as portal-of-entry providers, the acceptance and promotion of evidence-based health care, and a conservative clinical approach. Conclusion This paper presents the spine care model as a means of developing chiropractic cultural authority and relevancy. The model is based on principles that would help integrate chiropractic care into the mainstream delivery system while still retaining self-identity for the profession. PMID:16000175

    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.

    Objective The purpose of this case report is to describe the chiropractic management of a patient with Parkinson disease. Clinical features An 81-year-old male with a 12-year history of Parkinson disease sought chiropractic care. He had a stooped posture and a shuffling gait. He was not able to ambulate comfortably without the guidance of his walker. The patient had a resting tremor, most notably in his right hand. Outcome measures were documented using the Parkinson’s Disease Questionaire-39 (PDQ-39) and patient subjective reports. Intervention and outcome The patient was treated with blue-lensed glasses, vibration stimulation therapy, spinal manipulation, and eye-movement exercises. Within the first week of treatment, there was a reduction in symptoms, improvement in ambulation, and tremor. Conclusion For this particular patient, the use of alternative treatment procedures appeared to help his Parkinson disease signs and symptoms. PMID:25685120

  17. 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.

    2011-01-01

    Objectives The purpose of this case report is to describe the chiropractic management of a patient presenting with right arm paralysis and a diagnosis of Parsonage-Turner syndrome. Clinical Features After receiving nerve entrapment release surgery, a 30-year-old man presented with a right arm contracture, atrophy, and weakness with general paralysis of the forearm and index finger of 6 weeks' duration. Intervention and Outcome The patient was provided chiropractic care that included high-velocity/low-amplitude spinal manipulation based upon applied kinesiology manual muscle testing, soft tissue trigger point therapy, exercises, and stretches. The patient demonstrated improvement in range of motion after the first treatment session. By the eighth treatment, he was able to fully straighten his arm. Three years later, the patient reported that he was able to do mountain climbing and that his arm was fully functional and pain-free. Conclusion For this patient, chiropractic care seemed to be successful in relieving his right arm paralysis and restoring normal arm movement. PMID:22654689

  19. 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.

    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.

  5. Chiropractic and children: Is more research enough?

    PubMed Central

    2010-01-01

    Many health science research and review articles end with the words: "More research is needed". However, when it comes to research, it is not as much a question of quantity as of quality. There are a number of important prerequisites before research should be initiated. The three pillars, relevance, quality and ethics should be respected but for a project to be meaningful, it must also be based on plausible rationale. In evidence-based (informed) practice, one takes into account not only research-based evidence but also clinical expertise and the patients' perspectives. In this paper, we briefly discuss how this should be handled in clinical practice is briefly discussed, using the concept of "traffic lights" (red, yellow, green). We explain how the combination of evidence and plausibility can be used to reach a decision as to whether a treatment or diagnostic procedure is suitable, possible, or unsuitable. In this thematic series of Chiropractic & Osteopathy a number of reviews are presented, in which the research status of pediatric chiropractic is scrutinized and found wanting. Two important aspects were studied in these reviews: the effect of treatment and safety issues. Two types of problems were identified: the lack of research in general and the lack of research using the appropriate study designs and methodology in particular. Therefore, we discuss the meager research noted in the areas of chiropractic care in children and the clinical consequences this should have. The prerequisites for "more research" are scrutinized and an example given of suitable research programs. Finally, the important issue of implementation of research findings is covered, emphasizing the responsibility of all stakeholders involved at both the undergraduate and the postgraduate level, within professional associations, and on an individual level.

    Bova, Joseph; Sergent, Adam

    2014-01-01

    Objective The purpose of this case report is to describe the chiropractic management of a patient with idiopathic, intermittent right-sided hemiparesthesia. Clinical Features A 24-year-old woman presented with a 2-year history of intermittent idiopathic right arm paresthesia. She also had a 3-month history of intermittent idiopathic right leg/face paresthesia. These symptoms were strongest at night and caused insomnia and worsened over time. She rated her discomfort at 5/10 on a numeric scale. Intervention and Outcome Care included vibration stimulation therapy, spinal manipulation and cold laser therapy. She had a noticeable reduction in her paresthesia both subjectively and objectively. She showed improvement in paresthesia on the right side of her body after the first visit. The following week, after 2 visits she returned and stated that she was symptom free with 0/10 discomfort on a numeric scale. Conclusion This patient's symptoms of idiopathic, intermittent right-sided hemi-paresthesia seemed to improve with a short course of chiropractic care using manipulation, vibration therapy and cold laser therapy.

  7. Chiropractic and self-care for back-related leg pain: design of a randomized clinical trial

    PubMed Central

    2011-01-01

    Background Back-related leg pain (BRLP) is a common variation of low back pain (LBP), with lifetime prevalence estimates as high as 40%. Often disabling, BRLP accounts for greater work loss, recurrences, and higher costs than uncomplicated LBP and more often leads to surgery with a lifetime incidence of 10% for those with severe BRLP, compared to 1-2% for those with LBP. In the US, half of those with back-related conditions seek CAM treatments, the most common of which is chiropractic care. While there is preliminary evidence suggesting chiropractic spinal manipulative therapy is beneficial for patients with BRLP, there is insufficient evidence currently available to assess the effectiveness of this care. Methods/Design This study is a two-site, prospective, parallel group, observer-blinded randomized clinical trial (RCT). A total of 192 study patients will be recruited from the Twin Cities, MN (n = 122) and Quad Cities area in Iowa and Illinois (n = 70) to the research clinics at WHCCS and PCCR, respectively. It compares two interventions: chiropractic spinal manipulative therapy (SMT) plus home exercise program (HEP) to HEP alone (minimal intervention comparison) for patients with subacute or chronic back-related leg pain. Discussion Back-related leg pain (BRLP) is a costly and often disabling variation of the ubiquitous back pain conditions. As health care costs continue to climb, the search for effective treatments with few side-effects is critical. While SMT is the most commonly sought CAM treatment for LBP sufferers, there is only a small, albeit promising, body of research to support its use for patients with BRLP. This study seeks to fill a critical gap in the LBP literature by performing the first full scale RCT assessing chiropractic SMT for patients with sub-acute or chronic BRLP using important patient-oriented and objective biomechanical outcome measures.

    Spegman, Adele Mattinat; Herrin, Sean

    2007-01-01

    Objective: Psychological stress has been shown to influence learning and performance among medical and graduate students. Few studies have examined psychological stress in chiropractic students and interns. This preliminary study explored interns' perceptions around stress and confidence at the midpoint of professional training. Methods: This pilot study used a mixed-methods approach, combining rating scales and modified qualitative methods, to explore interns' lived experience. Eighty-eight interns provided ratings of stress and confidence and narrative responses to broad questions. Results: Participants reported multiple sources of stress; stress and confidence ratings were inversely related. Interns described stress as forced priorities, inadequate time, and perceptions of weak performance. Two themes, “convey respect” and “guide real-world learning,” describe faculty actions that minimized stress and promoted confidence. Conclusion: Chiropractic interns experience varying degrees of stress, which is managed with diverse strategies. The development of confidence appears to be influenced by the consistency and manner in which feedback is provided. Although faculty cannot control the amount or sources of stress, awareness of interns' perceptions can strengthen our effectiveness as educators. PMID:18483584

    Johnson, Claire

    2011-01-01

    The term subluxation has come to have different meanings for different health care professions in the United States for over the past century. This controversy has resulted in some contention both internal and external to the chiropractic profession. Some current factions within the chiropractic profession hold the term subluxation to be synonymous with the identity of chiropractic itself; however, this term was not solely used by chiropractic during its formative years. The purpose of this article is to look at uses of the term by various professions (osteopathy, medicine, and chiropractic) at the turn of the century, a time in which the chiropractic profession was developing.

    Houle, Sébastien

    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

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

    PubMed Central

    Keating, Joseph C; Rehm, William S

    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

    2011-01-01

    Purpose: The Journal of Chiropractic Education celebrates its 25th anniversary in the year 2011. The purpose of this article is to chronicle the history of the journal, which is unreported at this time. Methods: The entire collection of the journal was reviewed and information pertaining to important events and changes in the format, personnel, and processes of the journal were extracted. This information was used to create a chronology of the journal. The chronology was complemented with information obtained from people who were involved in the evolution of the journal and the Association of Chiropractic Colleges Educational Conferences. Results: Starting as a humble newsletter in 1987 and produced for a small cadre of readers primarily from the United States, the journal is now a full-sized and bound peer-reviewed international journal. Initially cataloged by the Index to Chiropractic Literature and MANTIS, the indexing expanded to interdisciplinary indexing systems such as CINAHL and ultimately PubMed. The journal has grown to serve the needs of chiropractic educators from around the world with representatives on the editorial board from 39 colleges and universities from 15 different countries. The journal has grown in tandem with the profession’s leading education and research conference and has been the primary repository for the scholarship of chiropractic education. Conclusion: The history of the journal represents a significant milestone in the development of the chiropractic profession, particularly the discipline of chiropractic education. The journal has had an interesting history and the future promises to bring more opportunities and challenges to the field of chiropractic education and to the journal. PMID:22069342

  13. Effects of Expanded Coverage for Chiropractic Services on Medicare Costs in a CMS Demonstration

    2016-01-01

    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

    Strunk, Richard G.; Pfefer, Mark T.; Dube, Derrick

    2014-01-01

    Objective The purpose of this case report is to describe multimodal chiropractic care of a female patient diagnosed with benign joint hypermobility syndrome (BJHS) and a history of chronic spine pain. Clinical features A 23-year-old white female presented for chiropractic care with chronic low back pain, neck pain, and headaches. The patient was diagnosed with BJHS, including joint hypermobility of her thumbs, elbows, right knee, and lumbopelvic region. A 6-year history of low back pain and varicose veins in her posterior thighs and knees were additional significant diagnostic findings of BJHS. Interventions and outcomes The treatment consisted of spinal and extremity manipulation, Graston technique, and postisometric relaxation combined with sensory motor stimulation and scapular stabilization exercises. The patient was seen 15 times over an 18-week period. After 18 weeks of care, the Revised Oswestry Low Back Questionnaire and Headache Disability Index demonstrated clinically important improvements with her low back pain and headache; but little change was noted in her neck pain as measured by the Neck Disability Index. Conclusion This patient with BJHS who had decreased disability and spine pain improved after a course of multimodal chiropractic care. PMID:24711783

    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.

    2013-01-01

    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.

  19. 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.

    Gorrell, Lindsay; Beirman, Robyn L.; Vemulpad, Subramanyam R.

    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.

  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.

  4. 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

  5. The Early Years of Organized Chiropractic Orthopedics, 1954–1973: A Social History

    PubMed Central

    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

    2015-03-01

    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.

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. PMID:25729083

    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

    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.

    Objective The purpose of this report is to describe chiropractic management, using a brain-based model of care, of a teen who had migraine headaches and several social and learning difficulties. Clinical features A 15-year-old adolescent boy with a chronic history of migraines and more than 10 years of learning and behavioral difficulties, including attention-deficit/hyperactivity disorder, obsessive compulsive disorder, and Tourette syndrome, presented for chiropractic care. Intervention and outcome The patient received spinal manipulation and was given home physical coordination activities that were contralateral to the side of the involved basal ganglia and ipsilateral to the involved cerebellum, along with interactive metronome training. Quantitative changes were noted in neurological soft signs, tests of variables of attention Conners’ Parent Rating Scale, the California Achievement Test, grade point, and reduction of medications. The patient reported qualitative improvements in tics, attention, reading, vision, health, relationships with his peers and his family, and self-esteem. Conclusion The patient with migraine headaches and learning difficulties responded well to the course of chiropractic care. This study suggests that there may be value in a brain-based model of care in the chiropractic management of conditions that are beyond musculoskeletal in nature. PMID:24396330

    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

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

    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.

    Objective: This report describes chiropractic management of a case of sub-acute elbow pain and swelling with Active Release Technique® and acupuncture. Case presentation: A 41-year-old male presented to a chiropractic clinic with a primary complaint of elbow pain and swelling following a fall while playing basketball five weeks prior. Intervention and Outcome: Treatment consisted of two sessions of needle acupuncture and one treatment of Active Release Techniques® (ART) applied to the left elbow region. Conclusions: The patient’s outcomes indicated a quick resolution of subjective complaints and objective findings with the chosen treatment. Further research is needed to demonstrate safety, clinical effectiveness, and cost effectiveness when compared to other treatments. PMID:24587497

  16. Horizontal integration of the basic sciences in the chiropractic curriculum.

    PubMed

    Ward, Kevin P

    2010-01-01

    Basic science curricula at most chiropractic colleges consist of courses (eg, general anatomy, physiology, biochemistry, etc) that are taught as stand-alone content domains. The lack of integration between basic science disciplines causes difficulties for students who need to understand how the parts function together as an integrated whole and apply this understanding to solving clinical problems. More horizontally integrated basic science curricula could be achieved by several means: integrated Part I National Board of Chiropractic Examiners questions, a broader education for future professors, an increased emphasis on integration within the current model, linked courses, and an integrated, thematic basic science curriculum. Horizontally integrating basic science curricula would require significant efforts from administrators, curriculum committees, and instructional faculty. Once in place this curriculum would promote more clinically relevant learning, improved learning outcomes, and superior vertical integration.

    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

    2001-01-01

    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.

    Objective: This study surveyed preceptor doctors' opinions of student competence before and after a chiropractic preceptorship. Methods: The qualitative and quantitative survey asked doctors about the competence of externs in various skills and asked opened-ended questions about the strengths and weaknesses of the externs. The survey was conducted using a common Web-based platform called SurveyMonkey. Results: A total of 125 doctors responded to the survey. The doctors tended to agree that they saw a positive change in the skills of the externs over time. Externs presented to the preceptors lacking in confidence and office management skills. The preceptors reported an increase from 2.7 to 3.9 on a 5.0 Likert scale in the students' confidence in adjusting skills during the preceptorship. The preceptor doctors were split on students' preparedness in chiropractic adjusting technique, reporting it as both the strongest and the weakest presenting skill. Conclusion: Preceptor doctors perceived that their student externs were academically qualified but were weaker in the clinical application of procedures. Results from this survey suggest that the preceptor program can improve the confidence levels and practice management knowledge of chiropractic externs. PMID:26600271

    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

  1. 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.

  4. 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.

    1997-01-01

    The purpose of this paper is to provide an historical review of the progression of events within the jurisdiction of the province of Ontario related to the issue of laboratory diagnosis and the profession of chiropractic. The provisions of relevant legislation, task forces, Councils, reviews, consensus statements, Commissions and committees, are highlighted and discussed during respective time periods. Chiropractors had entitlement to order and perform laboratory tests until 1972 when a regulatory amendment, made without consultation with the chiropractic profession, precluded their continuing entitlement. Chiropractic patients require access to diagnostic laboratory services and equitable access to necessary laboratory services should be restored and preserved. This is consistent with the academic institutional accreditation standards of chiropractic education and the jurisdictional regulatory mechanisms of chiropractic practice and is consistent with both protecting and enhancing the public interest.

    2016-04-01

    An outline of the minimum core competencies expected from a certified pediatric doctor of chiropractic was developed using a Delphi consensus process. The initial set of seed statements and substatements was modeled on competency documents used by organizations that oversee chiropractic and medical education. These statements were distributed to the Delphi panel, reaching consensus when 80% of the panelists approved each segment. The panel consisted of 23 specialists in chiropractic pediatrics (14 females) from across the broad spectrum of the chiropractic profession. Sixty-one percent of panelists had postgraduate pediatric certifications or degrees, 39% had additional graduate degrees, and 74% were faculty at a chiropractic institution and/or in a postgraduate pediatrics program. The panel were initially given 10 statements with related substatements formulated by the study's steering committee. On all 3 rounds of the Delphi process the panelists reached consensus; however, multiple rounds occurred to incorporate the valuable qualitative feedback received. PMID:26739669

    2014-01-01

    Background There are currently no widely accepted guidelines on standards for the practice of chiropractic or manual therapy manipulation under anesthesia, and the evidence base for this practice is composed primarily of lower-level evidence. The purpose of this project was to develop evidence-informed and consensus-based guidelines on spinal manipulation under anesthesia to address the gaps in the literature with respect to patient selection and treatment protocols. Methods An expert consensus process was conducted from August-October 2013 using the Delphi method. Panelists were first provided with background literature, consisting of three review articles on manipulation under anesthesia. The Delphi rounds were conducted using the widely-used and well-established RAND-UCLA consensus process methodology to rate seed statements for their appropriateness. Consensus was determined to be reached if 80% of the 15 panelists rated a statement as appropriate. Consensus was reached on all 43 statements in two Delphi rounds. Results The Delphi process was conducted from August-October 2013. Consensus was reached on recommendations related to all aspects of manipulation under anesthesia, including patient selection; diagnosis and establishing medical necessity; treatment and follow-up procedures; evaluation of response to treatment; safety practices; appropriate compensation considerations; and facilities, anesthesia and nursing standards. Conclusions A high level of agreement was achieved in developing evidence-informed recommendations about the practice of chiropractic/manual therapy manipulation under anesthesia. PMID:24490957

    Health science journals are a principle source of new knowledge for chiropractors, chiropractic faculty and students. Regrettably, clinically or educationally relevant articles (appearing in the nearly 20,000 journals annually) are often overlooked due to access difficulties. Innovations are needed to assist the reader to select articles relevant to chiropractic and reduce the time spent sorting through the volumes of literature. A review of the literature shows there is a trend toward database management for cataloging and accessibility of other, nonchiropractic, literature. Most notable of these is an endeavor by National Technical Information Service, commonly referred to as MEDLARS (Medline). It is interesting to note that a computer-assisted library database program does not exist on any chiropractic campus. This is in contrast with the trend on campuses of other health care fields. Manual search strategies within the chiropractic literature are time consuming, subject to a high failure rate, and even if the search produces citations, there is no assurance the journal can be accessed unless a chiropractic campus is nearby. Furthermore, difficulties exist when a chiropractic literature search is attempted in any computerized database, e.g., MEDLARS (Medline). Journals/articles that are unique to chiropractic (national, international or on the state level) are not specifically included in these computerized databases. Aside from these difficulties, there exists the problem of finding those articles that contain valid and relevant information from among those that are less valid or informative. PMID:2198323

    Objective: The life and contribution to chiropractic science of Dr. Ronald Gitelman is reviewed. Methods: Sources for this article included review of the notes prepared by Dr. Joseph Keating in his “biography” of the Canadian Memorial Chiropractic College (CMCC); review of the important articles published by Dr. Gitelman; review of the important projects undertaken by him along with various colleagues; notes from reminiscences obtained from many of these colleagues and discussions with his family. Discussion: Dr. Gitelman’s academic career spanned from 1963 to the late 1980’s. During that time, he made foundational contributions to the development of chiropractic science including: developing the Archives (1974), the first collection of scientific articles supporting chiropractic science (which was subsequently published as the Chiropractic Archives Research Collection (CRAC)); delivering one of the few chiropractic papers at the seminal NINCDS conference (1975) and, developing the collaboration between CMCC and Dr. Kirkaldy-Willis at the University of Saskatoon (1976). He practiced in Toronto from 1961 to 2007. Summary: Dr. Gitelman was a pioneer in the development of chiropractic science. He died on October 7, 2012. PMID:23482630

    Purpose To document the number of journal publications attributed to the academic faculty of Australian chiropractic tertiary institutions. To provide a discussion of the significance of this output and to relate this to the difficulty the profession appears to be experiencing in the uptake of evidence based healthcare outcomes and cultures. Methods The departmental websites for the three Australian chiropractic tertiary institutions were accessed and a list of academic faculty compiled. It was noted whether each academic held a chiropractic qualification or research Doctoral (not professional) degree qualification A review of the literature was conducted using the names of the academics and cross-referencing to publications listed independently in the PubMed and Index to Chiropractic Literature (ICL) databases (from inception to February 27 2006). Publications were excluded that were duplicates, corrected reprints, conference abstracts/proceedings, books, monographs, letters to the editor/comments or editorials. Using this information an annual and recent publication rate was constructed. Results For the 41 academics there was a total of 155 PubMed listed publications (mean 3.8, annual rate per academic 0.31) and 415 ICL listed publications (mean 10.1, annual rate 0.62). Over the last five years there have been 50 PubMed listed publications (mean 1.2, annual rate 0.24) and 97 ICL listed publications (mean 2.4, annual rate 0.47). Chiropractor academics (n = 31) had 29 PubMed listed publications (mean 2.5, annual rate 0.27) and 265 ICL listed publications (mean 8.5, annual rate 0.57). Academics with a doctoral degree (n = 13) had 134 PubMed listed publications (mean 10.3, annual rate 0.70) and 311 ICL listed publications (mean 23.9, annual rate 1.44). Academics without a Doctoral degree (n = 28) had 21 PubMed listed publications (mean 0.8, annual rate 0.13) and 104 ICL listed publications (mean 3.7, annual rate 0.24). Conclusion While several academics have compiled

    2010-01-01

    Social justice in public health involves the process and product of a community acting to fairly distribute advantages and burdens to improve the health of its population and to reasonably take care of the disadvantaged. Although publications are available about chiropractic public health history, programs, and policy, the potential role of chiropractic in social justice has received little attention. This article discusses Beauchamp's 4 principles of social justice and suggests actions that the chiropractic profession may consider to participate in the practice of social justice in the field of public health.

    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.

    Social justice in public health involves the process and product of a community acting to fairly distribute advantages and burdens to improve the health of its population and to reasonably take care of the disadvantaged. Although publications are available about chiropractic public health history, programs, and policy, the potential role of chiropractic in social justice has received little attention. This article discusses Beauchamp's 4 principles of social justice and suggests actions that the chiropractic profession may consider to participate in the practice of social justice in the field of public health.

    Introduction To make chiropractors more aware of menorrhagia and how they can serve a role in their patient’s care and education since women make up 60% of the population seeking chiropractic care. Method A review of the biomedical literature on menorrhagia was conducted. Items that were retrieved were synthesized and interpreted in order to give the best information to practicing chiropractors. Discussion Most of the information available relative to menorrhagia is medically oriented. Other treatment options can include: chiropractic, various types of herbs, and nutritional supplements. Conclusion Knowledge of medical treatment, nutritional supplements, along with chiropractic treatment options may be beneficial to doctors in their practice. PMID:18060009

    2012-01-01

    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

    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

    2011-01-01

    Introduction: Chiropractic students often serve as subjects in laboratories where they and their classmates practice examinations, various soft tissue techniques, physiological therapeutic modalities, and active rehabilitation. There are contraindications and risks associated with these procedures. This article describes how a procedure was developed to identify potential health concerns and risks that students may face while serving as subjects or performing procedures in clinical skills laboratories. Methods: Screening questions and examination procedures were developed through a consensus process. Findings from the screening process determine whether students may engage in full participation or limited participation (precautions) or are prohibited from receiving certain procedures (contraindications). Skills laboratory students and their instructors are informed of any identifiable precautions or contraindications to participation. Results: Since its implementation, precautions regarding delivery of manual therapies were found in 4% of those examined and precautions regarding receiving manual therapies in 11.5%. Contraindications to receiving specified manual therapies were found in 8%, and 4% had contraindications to certain physiological therapeutic modalities. Discussion: Further work is necessary to improve compliance with follow-up regarding diagnosis of conditions revealed or suspected. Future efforts should address how well students adhered to precautions and contraindications, the nature and frequency of injuries sustained within the laboratories, and what specific measures were taken by faculty to help students with special needs. Conclusion: This chiropractic college now has a method to describe potential risks, explain rules of laboratory participation, and obtain consent from each student. PMID:21677869

    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

    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

    In this pilot study, a collection of peer-reviewed articles from the Journal of the Canadian Chiropractic Association was analyzed by computer to identify the more commonly occurring words and phrases. The results were compared to a reference collection of general English in order to identify the vocabulary which is distinctive of chiropractic. From texts with a combined word count in excess of 280,000, it was possible to identify almost 2,500 words which were over-represented in the chiropractic literature and therefore likely to hold special importance within this domain. Additionally, readability statistics were calculated and suggest that the peer-reviewed chiropractic literature is approximately as challenging to read as that of nursing, public health and midwifery. Certain words widely considered to be of importance to the profession, for example “subluxation and adjustment,” were not particularly prevalent in the literature surveyed. PMID:21403783

    Chiropractic physicians are seeking a higher level of cultural authority within their communities and the United States health care system. This commentary suggests an innovative strategy that might expedite the attainment of professional authority while improving the training of chiropractic students and faculty. The authors propose the founding of integrative medicine centers of excellence by colleges of chiropractic that will employ clinical faculties comprised of allopathic, chiropractic, osteopathic, and naturopathic physicians. Initially, the health care facilities should offer primary care through an integrative medicine model. It is anticipated that these centers of excellence will require both government and private funding in order to develop research programs, provide high-quality patient care, and improve the medical training for students with residents programs PMID:18483589

    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. PMID:21120012

    Findings from a major study of chiropractic in British Columbia are used to illustrate the nature of limitations that should be considered in planning chiropractics future direction. Fifty chiropractors, 60 new clients of chiropractors and selected leaders of the chiropractic profession were interviewed on a variety of issues. Results indicate that sociopolitical factors limiting chiropractic include lack of access to public facilities, absence of representation in government services, lack of public funds for research and education, limits to reimbursement for services and low social valuation. Nine findings are identified as critical to future organizational plans. We suggest that a specific planning approach, such as the critical success factor (CSF) approach, be considered as a planning framework for organizational success in complex sociopolitical environments.

    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. PMID:26677851

    2016-01-01

    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.

    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

    2010-01-01

    Background Ice hockey is an international sport. Injuries occur in a full body fashion, to a number of tissues, commonly through body contact. There is a lack of literature documenting the scope of sports chiropractic practice. Thus, it was the aim to document the type, scope and severity of conditions presenting to, and the treatment provided by, the New Zealand team chiropractor acting as a primary health provider for the duration of the 2007 World Ice Hockey Championships. Methods All conditions presenting were recorded. Diagnosis was recorded along with clinical parameters of injury: injury type, severity, mechanism and whether referral or advanced imaging was required. All treatment provided was continuously recorded, including information on the number of treatments required and the reason, duration, type and location of treatment. Results Players presented for diagnosis of injury 50 times. Muscle (34%), joint (24%) and tendon injuries (18%) were most common. Players presented with a new injury 76% of the time. Most injuries had been present for less than one week (84%), with 53% occurring through a contact mechanism. Injuries were common at training and match locations. Only two injuries required the player to stop playing or training, both of which were referred for advanced imaging. During the study, 134 treatment consultations were rendered to 45 player injuries. Eighty per-cent of injuries were managed with four or less treatments. Three quarters of treatment was provided at training locations with treatment duration predominantly being between 11-15 minutes (71%) and 16-20 minutes (27%). Most treatment delivered was passive in nature (71%) although combination active and passive care was provided (27%). Treatment typically involved joint (81%) and soft tissue based therapies (81%) and was delivered in a full body manner. Conclusions This study documented the injury profile of ice hockey at an international level of competition. It documented the

    Health and lifestyle early in life have profound impact on health and quality of life in later years. Common public health problems such as musculoskeletal disorders, cardiovascular disease, and depression tend to cluster in individuals, and this pattern is established early. At present, no health care profession has convincingly assumed the responsibility of spinal and musculoskeletal health for children. Considering the magnitude of the challenges ahead for both researchers and clinicians, this may be a good opportunity for doctors of chiropractic to take responsibility and engage in a determined effort to bring forward evidence-based strategies for prevention of spinal pain and other musculoskeletal problems. Chiropractors may play a significant role in finding and implementing evidence-based prevention and treatment strategies aimed at infants, children, and adolescents.

    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

    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 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.

    Background To investigate the presence of pathogenic microbes on chiropractic treatment tables in one outpatient teaching clinic. Additional aims were to test inexpensive disinfectants on tables that may kill microbes and suggest infection control measures for chiropractic offices, clinics and classrooms. The aim of the study was to assess the presence of pathogenic microbes on treatment tables in one outpatient teaching clinic and determine a simple behavioral model for infection control including table disinfection and accepted hand washing and sanitizing protocols. Methods 10 treatment tables were selected and sampled for possible microbial flora on face and hand pieces. Samples were cultured on MacConky's agar and mannitol salt agar, labeled and incubated for up to 48 hours. Confirmatory testing of microbes to determine if drug resistant flora were present was performed. Among tables tested, 5 were selected to test disinfectants. One-half of the face piece and 1 hand piece were treated with two different wipes and then post-tested for microbes. Results Pathogenic microbes were present on chiropractic treatment tables including methicillin-resistant Staph aureus. Simple disinfectants neutralized the pathogens. A rudimentary disinfection procedure and infection control measures are suggested based on the findings. Conclusion Pathogenic microbes may be present on chiropractic treatment tables and can be effectively killed with proper disinfecting. Hand washing/sanitizing is an important measure in infection control as is table disinfecting. Rudimentary behavioral changes to improve chiropractic clinic infection control are needed. More comprehensive behavioral models are needed. All teaching clinics and private chiropractic offices should adopt infection control practices including routine table disinfecting and hand sanitizing. Effective measures can be put in place at minimal costs. Accrediting bodies of chiropractic institutions should mandate an infection

    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

[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. PMID:27190435

    There is a growing desire within the chiropractic profession to expand the scope of practice to include limited medication prescription rights for the treatment of spine-related and other musculoskeletal conditions. Such prescribing rights have been successfully incorporated into a number of chiropractic jurisdictions worldwide. If limited to a musculoskeletal scope, medication prescription rights have the potential to change the present role of chiropractors within the healthcare system by paving the way for practitioners to become comprehensive specialists in the conservative management of spine / musculoskeletal disorders. However, if the chiropractic profession wishes to lobby to expand the scope of practice to include limited prescriptive authority, several issues must first be addressed. These would include changes to chiropractic education and legislation, as well as consideration of how such privileges could impact the chiropractic profession on a more theoretical basis. In this commentary, we examine the arguments in favour of and against limited medication prescription rights for chiropractors and discuss the implications of such privileges for the profession.

    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.

    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 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.

    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

    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 : We assessed the level of students' test anxiety, and the relationship between test anxiety and academic performance. Methods : We recruited 166 third-quarter students. The Test Anxiety Inventory (TAI) was administered to all participants. Total scores from written examinations and objective structured clinical examinations (OSCEs) were used as response variables. Results : Multiple regression analysis shows that there was a modest, but statistically significant negative correlation between TAI scores and written exam scores, but not OSCE scores. Worry and emotionality were the best predictive models for written exam scores. Mean total anxiety and emotionality scores for females were significantly higher than those for males, but not worry scores. Conclusion : Moderate-to-high test anxiety was observed in 85% of the chiropractic students examined. However, total test anxiety, as measured by the TAI score, was a very weak predictive model for written exam performance. Multiple regression analysis demonstrated that replacing total anxiety (TAI) with worry and emotionality (TAI subscales) produces a much more effective predictive model of written exam performance. Sex, age, highest current academic degree, and ethnicity contributed little additional predictive power in either regression model. Moreover, TAI scores were not found to be statistically significant predictors of physical exam skill performance, as measured by OSCEs.

    During their long careers of counseling couples, Giovanna Stoll and Maurice Hurni have encountered couples in which psychological violence is exercised. Their book, ¿The Hate of Love, the Oddness of the Place,¿ explores strategies used in couples by one or both partners to subjugate the other and to be victorious in an ongoing struggle between the two. Two case examples are presented. Confronted with such deliberate meanness, health professionals long ago adopted a neutral stance on such behavior in an attempt to maintain professional distance from their clients. However, Stoll and Hurni abandoned their neutrality in the face of certain particularly brutal behaviors. The author describes Stoll and Hurni¿s professional experiences and the children of manipulative parents. The employer who pits his employees against each other is also discussed. Such manipulators are unable to have true friends, just as they are unable to live within loving, communicative relationships. They behave in calculated fashion, having only relationships which they deem to be useful and opportune. Respect, the capacity to give and receive, and empathy are alien notions to those who manipulate others. 40% of 1500 women aged 20-60 years old interviewed in a study of violence within the family report having been subjected to psychological violence during their married lives. 14% of these women report being either often or always sad. Women risk being denigrated, humiliated, harassed, controlled, and deprived.

  14. 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

    The philosophy of chiropractic has always been regarded as an integral and indispensable component of the curriculum at chiropractic colleges. This study describes a review process in which instruments were designed to survey students and faculty to obtain information concerning curricular aspects of philosophy at the Canadian Memorial Chiropractic College. Approximately one half of the student body (N = 292) and sixty percent of the full-time and part-time faculty members (N = 66) responded to the surveys. The students who were surveyed indicated that philosophy was a very important part of their chiropractic education and they felt that their needs in this regard were not being met by the present program. Further, they perceived most faculty as being unappreciative of philosophy. The results from the faculty survey were at odds with the students’ perceptions and indicated that the faculty members were favourably disposed towards philosophy and felt that it should be an integral part of the students’ educational experience. The information gained from these surveys was subsequently used as a catalyst to stimulate discussion in a series of student/faculty focus groups on philosophy. These discussions helped to clarify some curricular philosophical issues and resulted in specific modifications to the philosophy program in the areas of content, format, faculty, and evaluation methods.

    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

    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.

  6. Spinal manipulation under anesthesia: a narrative review of the literature and commentary

    PubMed Central

    2013-01-01

    As exhibited throughout the medical literature over many decades, there is a lack of uniformity in the manner in which spine pain patients have historically qualified for and received manipulation under anesthesia (MUA). Also, for different professions that treat the same types of spinal conditions via the same means, fundamental MUA decision points vary within the published protocols of different professional associations. The more recent chiropractic literature communicates that the evidence to support the efficacy of MUA of the spine remains largely anecdotal. In addition, it has been reported that the types of spinal conditions most suitable for MUA are without clear-cut consensus, with various indications for MUA of the low back resting wholly upon the opinions and experiences of MUA practitioners. This article will provide a narrative review of the MUA literature, followed by a commentary about the current lack of high quality research evidence, the anecdotal and consensus basis of existing clinical protocols, as well as related professional, ethical and legal concerns for the chiropractic practitioner. The limitations of the current medical literature related to MUA via conscious/deep sedation need to be recognized and used as a guide to clinical experience when giving consideration to this procedure. More research, in the form of controlled clinical trials, must be undertaken if this procedure is to remain a potential treatment option for chronic spine pain patients in the chiropractic clinical practice.

    2015-01-01

    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

    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.

    To assess the effect of chiropractic use on overall health care utilization patterns, the volume and pattern of ambulatory physician visits by elderly persons having contact with chiropractors are compared with those having contact with physicians only. This analysis is based on data representative of the Canadian Province of Manitoba's entire elderly population; they are drawn from interviews and from claims filed routinely as part of Manitoba's universally insured health care services. The results show that chiropractic services do not substitute for physician services among the elderly in a province which fully insures medical services and a limited number of chiropractic visits. The data suggest that, under these conditions, some elderly chiropractic users consume more physician services than other elderly of equal health status, in addition to visiting chiropractors.

    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

    The inability to predict outcome in patients with low back/neck pain leads to inappropriate or unnecessary treatment. The aims of the study were to identify prognostic factors for disability at 1-year follow-up in patients with back pain visiting primary care, and to compare the effect of these in two treatment strategies--chiropractic and physiotherapy. Data were taken from a randomised trial on patients with back/neck pain visiting the general practitioner, in which patients were allocated to chiropractic and physiotherapy as primary management. Three hundred and twenty-three patients, aged 18-60 years, who had no contraindications to manipulation and who had not been treated within the previous month were included in the study. Multiple regression analysis was used to identify prognostic factors. Dependent variables were mean Oswestry score and mean change in Oswestry score at 12-month follow-up. The multiple regression analysis revealed five significant (P < 0.001-0.01) prognostic factors; duration of current episode, Oswestry score at entry, expectations of treatment, number of localisations, and well-being. Besides, the regression coefficients for the significant factors were compared between the two treatment strategies. No significant difference in effect or regression coefficients for the prognostic factors were seen between the two treatment strategies. Twelve per cent of the patients had poor prognostic factors (duration > or = 1 month, more than one localisation, low expectations of treatment and low well-being) at entry. These patients had a mean Oswestry score above 20% at 1-year follow-up. Clinical decision models for the management of patients with back pain visiting primary care that consider prognostic factors need to be implemented and prospectively evaluated.

    Objectives: To describe the extent to which chiropractors utilize standardized outcome and various clinical measures to systematically document patients’ baseline health status and responses to treatment, with particular consideration being given towards quantifiable outcome instruments. Study design: Cross-sectional mailed survey. Participants: Registered chiropractors in the province of Saskatchewan. Methods: A survey was mailed to all registrants of the Chiropractors’ Association of Saskatchewan. Respondents graded their frequency of using various standardized pencil-and-paper instruments and functional chiropractic, orthopaedic and neurological tests in the contexts of both the initial intake assessment (‘always,’ ‘commonly,’ ‘occasionally,’ or ‘never’) and the course of subsequent treatment (after ‘each visit,’ after ‘9–12 visits,’ ‘annually,’ when patient ‘not responding,’ on ‘dismissal/discharge,’ ‘never’ or for some ‘other’ reason). Data were tabulated for all item and response category combinations as frequencies and percentages using the total sample size as the denominator. Results: Of 164 registered chiropractors, 62 (38%) returned a completed questionnaire. A pain diagram was the most commonly used subjective outcome measure and was administered routinely (either “always” or “commonly”) by 75% of respondents, at either the initial consultation or during a subsequent visit. Numerical rating and visual analogue scales were less popular (routinely used by 59% and 42% respectively). The majority of respondents (80%) seldom (“occasionally” or “never”) used spine pain-specific disability indices such as the Low Back Revised Oswestry, Neck Disability Index or the Roland-Morris Questionnaire. As well, they did not use standardized psychosocial instruments such as the Beck Depression Index, or general health assessment measures such as the SF-36 or SF-12 questionnaire. Neurological testing was

    2013-01-01

    Background Evidence-based clinical practice (EBCP) is a practice model gaining prominence within healthcare, including the chiropractic profession. The status of EBCP has been evaluated in a variety of healthcare disciplines, but little is known regarding the attitudes doctors of chiropractic (DCs) hold toward this model of healthcare. This project examines the attitudes toward EBCP within a specialty discipline of DCs. Methods We identified a survey questionnaire previously used to evaluate EBCP among non-chiropractic complementary and alternative practitioners. We adapted this questionnaire for use among DCs and pretested it in 5 chiropractic college faculty. The final version was administered to DCs with diplomate-level training in orthopedics. The survey was emailed to 299 potential participants; descriptive results were calculated. Results 144 surveys were returned, resulting in a 48% response rate. The majority of respondents perceived EBCP as an important aspect of chiropractic practice. Respondents also believed themselves to have an above average skill level in EBCP, reported that training originated from their diplomate education, and based the majority of their practice on clinical research. Conclusion Doctors of chiropractic with an orthopedic diplomate appear to have favorable attitudes toward EBCP. Further study will help understand EBCP perceptions among general field DCs. A logical next step includes validation of this questionnaire. PMID:24314309

    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

    Objective The purpose of this study was to examine how chiropractic care compares to medical treatments on one-year changes in self-reported function, health, and satisfaction with care measures in a representative sample of Medicare beneficiaries. Methods Logistic regression using generalized estimating equations (GEE) is used to model the effect of chiropractic relative to medical care on decline in five functional measures and two measures of self-rated health among 12,170 person-year observations. The same method is used to estimate the comparative effect of chiropractic on six satisfaction with care measures. Two analytic approaches are used, the first assuming no selection bias and the second using propensity score analyses to adjust for selection effects in the outcome models. Results The unadjusted models show chiropractic is significantly protective against one-year decline in ADLs, lifting, stooping, walking, self-rated health, and worsening health after one year. Persons using chiropractic are more satisfied with their follow-up care and with the information provided to them. In addition to the protective effects of chiropractic in the unadjusted model, the propensity score results indicate a significant protective effect of chiropractic against decline in reaching. Conclusion This study provides evidence of a protective effect of chiropractic care against one-year declines in functional and self-rated health among Medicare beneficiaries with spine conditions, and indications that chiropractic users have higher satisfaction with follow-up care and information provided about what is wrong with them.

    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

    A review of meditation techniques indicates that the suppression of inner speech by the use of a "mental devise" may be a key factor in generating the relaxation response of this procedure. It is hypothesized that the suppression of inner speech would release the diaphragm, temporomandibular joint muscles, and hyoid muscles from "symbolic duty." The structural implications of this hypothesis are explored, particularly as they may relate to the treatment of orthopedic disorders commonly seen in chiropractic practices.

    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.

    Background Several studies have reported on the health benefits of applying an integrated complementary health care model. Purpose This paper presents the results of pilot research focusing on the observations massage therapy students made about complementary health care education and integration during massage, chiropractic, and acupuncture treatments at two university clinics. Setting: Observations took place at Northwestern Health Sciences University’s associated clinics that offered massage, chiropractic, and acupuncture. Research Design: Students directly observed how clinicians and interns educated their patients and integrated other forms of complementary health care into their practice. Participants: chiropractors, massage therapists, and acupuncturists, and their patients. All participants were English-speaking and 18–65 years old. Main Outcome Measures: Observations recorded by students in journals about education and integration during massage therapy, chiropractic, and acupuncture treatments were coded and counted. Results Qualitative observations showed that clinicians and interns educated patients to some degree, but the clinicians were less apt to integrate other modalities than the interns. Conclusions Observations support that professional integrity may limit clinicians in their ability to integrate multiple modalities of health care while treating patients. Since it is well established that integration of multiple health care modalities is beneficial to patient health, it is recommended that clinics assist their clinical staff in applying an integrative approach to their practice.

    A questionnaire was designed and mailed to the entire membership (no. = 438) of the San Francisco Bay Area Chiropractic Society to determine their nutrition education backgrounds and counseling practices and the relationship of backgrounds and counseling practices and the relationship of backgrounds and information resources to counseling practices. Results, based on the 23% response rate, indicated that the hours of formal nutrition education in chiropractic college varied widely in the five categories of responses from zero to more than 120, with the median respondent falling in the median category (81 to 100 hours). Sixty percent of the respondents indicated that they provided nutrition information to their patients on a routine basis, and 38% provided information on request only. The major forms of nutrition information dissemination were counseling (87%) and written materials (74%). The majority of respondents reported that they diagnose osteoporosis, arthritis, and allergies and use nutrition treatments for those disorders as a part of overall therapy. Chiropractic journals and texts were the most frequently used sources of nutrition information. Awareness of the educational backgrounds of registered dietitians correlated positively with the use of dietitians as a resource for nutrition information (p less than .005). The survey results suggest a need for dietitians to become involved in the nutrition-related practices of chiropractors as sources for information and referral.

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

    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.

    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.

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.

    Abstract Objective This randomized controlled study was designed to determine the pain-relieving effect of Biofreeze (Performance Health Inc., Export, PA) body surface application and chiropractic adjustments on subjects with acute low back pain (LBP). Methods The data were collected at the baseline, 2 weeks after treatment, and 4 weeks after treatment for final analyses. Diversified manual adjustments were provided by licensed chiropractors twice a week for 4 weeks to both control and experimental groups. Biofreeze was applied to the lower back area 3 times a day for 4 weeks in the experimental group. Outcome assessments included visual analog scale, Roland Morris Disability Questionnaire, heart rate variability for stress, and electromyography for low back muscle activity. Results A total of 36 subjects were recruited in the study (25 male). The average age was 34 years. Significant pain reduction was found after each week of treatment in the experimental group (P < .05). The Roland Morris Disability Questionnaire did not show significant changes in both groups. There were no significant differences for pain reduction in the control group. Heart rate variability analysis showed no significant change (P > .05) in the experimental group after 4 weeks of Biofreeze and chiropractic adjustments. There were no statistically significant changes in the electromyography readings between the 2 groups. Conclusion Biofreeze combined with chiropractic adjustment showed significant reduction in LBP.

    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.

    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.

    Objective To compile baseline data regarding the treatment practices and therapeutic outcomes that fellows of the College of Chiropractic Sports Sciences Canada (CCSS(C)) strive for when treating athletes. Design Cross-sectional self-report mail out survey of CCSS(C) fellows. Participants Current registered fellows of the CCSS(C) as determined by the College at the time of survey distribution. Results The majority of questioned fellows believe that they can cause direct and specific improvements in an athlete’s sport performance. The most commonly utilized therapeutic intervention was spinal joint manipulation/mobilization. The most anticipated outcomes following the treatment of athletes with the goal of affecting athletic performance were “changing or improving aberrant body mechanics,” “restoring or improving aberrant muscle function,” and “improving joint function or reducing joint dysfunction.” Conclusion The majority of respondent fellows of the CCSS(C) believe their therapy to be effective in enhancing an athlete’s sport performance.

    Background Descriptive studies of chiropractic patients are not new, several have been performed in the U.S., Australia, Canada, and Europe. None have been performed in a Latin American country. The purpose of this study is to describe the patients who visited a Mexican chiropractic college public clinic with respect to demographics and clinical characteristics. Methods This study was reviewed and approved by the IRB of Parker College of Chiropractic and the Universidad Estatal del Valle de Ecatepec (UNEVE). Five hundred patient files from the UNEVE public clinic from May 2005 to May 2007 were selected from an approximate total number of 3,700. Information was collected for demographics, chief complaints, associated complaints, and previous care sought. Results The sample comprised 306 (61.2%) female. Most files (44.2%) were in the age range of 40–59 years (mean of 43.4 years). The most frequent complaints were lumbar pain (29.2%) and extremity pain (28.0%), most commonly the knee. Most (62.0%) described their complaints as greater than one year. Trauma (46.6%) was indicated as the initial cause. Mean VAS score was 6.26/10 with 20% rated at 8/10. Conclusion Demographic results compared closer to studies conducted with private clinicians (females within the ages of 40–59). The primary complaint and duration was similar to previous studies (low back pain and chronic), except in this population the cause was usually initiated by trauma. The most striking features were the higher number of extremity complaints and the marked increased level of VAS score (20% rated as 8/10). PMID:19298656

    Purpose: The impact of the educational environment in student learning is well documented. However, there is a scarcity in the literature exploring the educational environment in chiropractic training institutions. This study aimed to identify the perceived educational environment in a chiropractic training institution and the possible perceptual differences among different demographic groups. Methods: The perceived educational environment was surveyed using Dundee Ready Education Environment (DREEM), which is a validated, self-administered, and Likert-type inventory. DREEM items focus on subdomains related to learning, teachers, self-confidence, academic atmosphere, and social environment. The results were analyzed and interpreted in relation to standard norms of DREEM and demographic variables. Results: The survey was completed by 124 chiropractic undergraduate students (response rate 83%). Statistically, the inventory items showed high correlation and the subdomains showed a close relationship. Overall the DREEM score was very high: 156.1/200 (78%). The subdomain scores were also at very high levels. However, the scoring of four items by students was consistently poor: lack of a support system for stressed students, 1.8 (SD 1.1); authoritarian teachers, 1.8 (SD 1.2); inadequate school time-tabling, 2.0 (SD 1.1); and overemphasis on factual learning, 2.0 (SD 1.0). There were no statistically significant differences in DREEM scores between gender, age, minority, and ethnicity groups. Conclusions: In general, students perceived that a sound educational environment is fostered by the institution and its educational program for all students despite their demographic variations. However, certain specific elements of the educational process may need to be addressed to improve the educational experience. PMID:22069340

Part II, delves into the life of Archie’s brother Samson, and Samson’s chiropractic progeny: grandsons David and Neil, and great granddaughter Megan. Then it goes back to look at Stephen West’s nephew, R. Ian Buchanan and ends with a descendant of another branch of the family tree, James L. West. PMID:21629465

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

    PubMed Central

    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

    Fractures of the scapula are relatively uncommon. Fractures specific to the scapular body comprise 35–65% of these fractures. Currently, 99% of all isolated scapular body fractures are being treated nonoperatively with an immobilizing sling or brace and some form of manual therapy with an 86% success rate. We present the conservative management of three patients with comminuted fractures involving the scapular body that were managed in chiropractic settings. Residual disabilities in these three patients as measured by a standardized outcome tool were 2%, 5% and 23% after 3 years, 2 years, and 6 years respectively. PMID:23754863

  18. Case management of chiropractic patients with cervical brachialgia: A survey of French chiropractors

    PubMed Central

    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

    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

    2014-01-01

    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 management of patellofemoral pain syndrome has not been well documented. A time-series experimental design was employed to assess the effectiveness of chiropractic care during the symptomatic control phase in a patient with bilateral knee pain. Treatment consisted of long axis tibiofemoral adjustment, passive patellofemoral mobilization, and continuous ultrasound. Mediating variables, derived from physical examination findings, were subject to periodic randomized observation sampling by a second observer who was blinded to the first observer, but unblinded to the experimental phases. Strong interexaminer reliability (K = 0.78, p less than .005) was observed for patellar tracking jitter. Poor agreement (K = 0.31, NS) was observed for the patellar grinding test graded on an oridinal scale, but moderate interexaminer agreement (K = 0.52; p less than .01) was obtained with the test on a nominal scale. Clinical outcome measures of pain, patellar tracking, and patellar grinding tests were observed to visually covary throughout the experiment. A reliable 3-4 wk lag was observed between treatment phases and demonstrable changes in the patient's signs and symptoms. PMID:2273335

    Objective This case report describes the diagnosis of a malignant brain tumor in a patient requesting chiropractic care for headaches after a motor vehicle accident. Clinical Features A 30-year-old man presented with numbness and tingling in all extremities, lower extremity muscle weakness, and a recent increase in headaches with the loss of ability to concentrate. He was involved in a high-speed motor vehicle collision approximately 4 months before the onset of symptoms. Examination showed slow gait with a lack of arm swing, bilateral hip flexors and knee extensors were all graded as 4/5 on muscle testing, and cranial nerve examination was unremarkable with the exception of 2 beats of nystagmus on left lateral eye movement. Because of these findings and a family history of multiple sclerosis, the patient was referred for a brain magnetic resonance imaging scan. Intervention and Outcome Imaging showed a craniocervical junction mass centered at the floor of the fourth ventricle with obstruction of foramina and marked impingement on the medulla. A posterior fossa craniotomy and tumor removal procedure was performed by a neurosurgeon, followed by 34 sessions of radiation therapy. The final diagnosis was a grade II glioma with features of ependymoma. Conclusions This report describes the clinical presentation, examination, and medical management of a 30-year-old man presenting to a chiropractic practice with an unsuspected malignant brain tumor.

    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

    Introduction The purpose of this case report is to describe the clinical presentation, examination findings, and management decisions of a patient with thoracic myelopathy who presented to a chiropractic clinic. Case Report/Methods After receiving a diagnosis of a diffuse arthritic condition and kidney stones based on lumbar radiograph interpretation at a local urgent care facility, a 45-year-old woman presented to an outpatient chiropractic clinic with primary complaints of generalized low back pain, bilateral lower extremity paresthesias, and difficulty walking. An abnormal neurological examination result led to an initial working diagnosis of myelopathy of unknown cause. The patient was referred for a neurological consult. Results Computed tomography revealed severe multilevel degenerative spondylosis with diffuse ligamentous calcification, facet joint hypertrophy, and disk protrusion at T9-10 resulting in midthoracic cord compression. The patient underwent multilevel spinal decompressive surgery. Following surgical intervention, the patient reported symptom improvement. Conclusion It is important to include a neurologic examination on all patients presenting with musculoskeletal complaints, regardless of prior medical attention. The ability to recognize myelopathy and localize the lesion to a specific spinal region by clinical examination may help prioritize diagnostic imaging decisions as well as facilitate diagnosis and treatment.

    Wall, James C; Turnbull, George I; Vernon, Howard

    1988-01-01

    This paper compares the efforts of physiotherapy and chiropractic to move towards the development of a scientific body of knowledge through research. The history of both professions is discussed with particular reference to the education of the clinical practitioners and the educational faculty. Four cited factors contributing to the paucity of research in chiropractic, namely anti-scientific elements in philosophy, lack of suitable role-models, lack of funds and a lack of understanding of research methodology are also seen as barriers to physiotherapy research. These obstacles are discussed in the light of the strategies being employed by both professions to deal with this issue and their success or otherwise. It is stressed that research by members of both professions is fundamental to ensure professional survival. Solutions are principally concerned with increasing the research output from those institutions which educate future professionals. This new generation will likely ensure that the professions are soundly based on scientific principles. The paper considers, therefore, the pre-professional curriculum primarily, although not exclusively, from a Canadian perspective.

    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.

    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.

    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.

    2010-01-01

    Background Hamstring injuries are the most common injury in Australian Rules football. It was the aims to investigate whether a sports chiropractic manual therapy intervention protocol provided in addition to the current best practice management could prevent the occurrence of and weeks missed due to hamstring and other lower-limb injuries at the semi-elite level of Australian football. Methods Sixty male subjects were assessed for eligibility with 59 meeting entry requirements and randomly allocated to an intervention (n = 29) or control group (n = 30), being matched for age and hamstring injury history. Twenty-eight intervention and 29 control group participants completed the trial. Both groups received the current best practice medical and sports science management, which acted as the control. Additionally, the intervention group received a sports chiropractic intervention. Treatment for the intervention group was individually determined and could involve manipulation/mobilization and/or soft tissue therapies to the spine and extremity. Minimum scheduling was: 1 treatment per week for 6 weeks, 1 treatment per fortnight for 3 months, 1 treatment per month for the remainder of the season (3 months). The main outcome measure was an injury surveillance with a missed match injury definition. Results After 24 matches there was no statistical significant difference between the groups for the incidence of hamstring injury (OR:0.116, 95% CI:0.013-1.019, p = 0.051) and primary non-contact knee injury (OR:0.116, 95% CI:0.013-1.019, p = 0.051). The difference for primary lower-limb muscle strains was significant (OR:0.097, 95%CI:0.011-0.839, p = 0.025). There was no significant difference for weeks missed due to hamstring injury (4 v14, χ2:1.12, p = 0.29) and lower-limb muscle strains (4 v 21, χ2:2.66, p = 0.10). A significant difference in weeks missed due to non-contact knee injury was noted (1 v 24, χ2:6.70, p = 0.01). Conclusions This study demonstrated a trend

    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.

    Introduction This study had two purposes. These were: (i) to conduct a search of the literature between 2007 and 2011 investigating the use of spinal manipulative therapy (SMT) for pediatric health conditions and (ii) to perform a systematic review of eligible retrieved clinical trials. Methods The Index of Chiropractic Literature and PubMed were electronically searched using appropriate search words and MeSH terms, respectively, as well as reference tracking of previous reviews. Studies that met the inclusion criteria were evaluated using an instrument that assessed their methodological quality. Results Sixteen clinical trials were found that met the inclusion criteria and were scored. Discussion Six clinical trials investigated the effectiveness of SMT on colic, two each on asthma and enuresis, and one each on hip extension, otitis media, suboptimal breastfeeding, autism, idiopathic scoliosis and jet lag. None investigated the effectiveness of SMT on spinal pain. Conclusion Studies that monitored both subjective and objective outcome measures of relevance to both patients and parents tended to report the most favorable response to SMT, especially among children with asthma. Many studies reviewed suffered from several methodological limitations. Further research is clearly required in this area of chiropractic health care, especially with respect to the clinical effectiveness of SMT on pediatric back pain. PMID:22675226

    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

    Study Design. Baseline description of a multicenter cohort study. Objective. To describe patients with low back pain (LBP) in both chiropractic and general practice in Denmark. Background. To optimize standards of care in the primary healthcare sector, detailed knowledge of the patient populations in different settings is needed. In Denmark, most LBP-patients access primary healthcare through chiropractic or general practice. Methods. Chiropractors and general practitioners recruited adult patients seeking care for LBP. Extensive baseline questionnaires were obtained and descriptive analyses presented separately for general and chiropractic practice patients, Mann-Whitney rank sum test and Pearson's chi-square test, were used to test for differences between the two populations. Results. Questionnaires were returned from 934 patients in chiropractic practice and 319 patients from general practice. Four out of five patients had had previous episodes, one-fourth were on sick leave, and the LBP considerably limited daily activities. The general practice patients were slightly older and less educated, more often females, and generally worse on all disease-related parameters than chiropractic patients. All differences were statistically significant. Conclusions. LBP in primary care was recurrent, causing sick leave and activity limitations. There were clear differences between the chiropractic and general practice populations in this study.

    A transfer platform for the conveyance of objects by a manipulator includes a bed frame and saddle clamp secured along an edge of the bed frame and adapted so as to secure the bed frame to a horizontal crosspiece of the manipulator. The platform may thus move with the manipulator in a reciprocal linear path defined by a guide rail. A bed insert may be provided for the support of conveyed objects and a lifting bail may be provided to permit the manipulator arm to install the bed frame upon the crosspiece under remote control.

    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.

    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 cost of care and the number of days lost because of work injury were analyzed from information gathered in a postal card survey sent to all Iowa back or neck injury claimants (sprain/strain) on record for 1984. Descriptive findings for the flow of care of the respondents were evaluated and a comparison made of the benefits and costs of care received by patients treated by chiropractic doctors (DCs), medical doctors (MDs) or osteopathic doctors (DOs). The analysis focused on those workers who lost enough time from work to qualify for compensation (4 days or more), whose cases were closed and who received all their care from one health professional. For those who received care from DCs (n = 266), the mean number of compensated days lost from work was at least 2.3 days less than for those who were treated by MDs (n = 494; p less than 0.025) and at least 3.8 days less than for those who were treated by DOs (n = 102; p less than 0.025). Consequently, much less money in employment compensation was paid, on the average, to those who saw DCs. Findings on provider care costs are less clear-cut because care-cost data on only a portion of the cases was recorded on the State records used. For the data available, the median provider cost was highest for patients who saw DCs, but the mean was highest for those who saw MDs. The study showed that 38% of claimants did change doctors. When change of provider occurred, days lost from work and cost of care varied widely across the care options, but generally, fewer workdays were lost and lower amounts of disability compensation and provider cost paid when chiropractic was included in the care pattern.

    Abstract Objective This study retrospectively examined the effects of a 21-day nutritional intervention program, which included fruit and vegetable consumption, energy restriction, and nutritional supplements, on serum lipid measures in 28 chiropractic patients. Methods Medical records were reviewed for 28 chiropractic patients who had completed a commercially available 21-day nutritional intervention program between April 2005 and August 2007 and for whom complete serum lipid and weight measures immediately pre- and postintervention were available. The primary outcome was change in serum lipids, and change in body weight was a secondary outcome variable. Results Significant reductions in total, low-density lipoprotein, very low-density lipoprotein, and high-density lipoprotein cholesterol, and triglycerides were observed. Serum triglycerides decreased from 116.3 ± 54.6 (mean ± SD) to 88.6 ± 40.5 mg/dL (P < .01). Total cholesterol decreased from 223.3 ± 40.7 to 176.2 ± 30.0 mg/dL (P < .0001). Low-density lipoprotein cholesterol decreased from 145.7 ± 36.8 to 110.9 ± 25.3 mg/dL (P < .0001). High-density lipoprotein cholesterol decreased from 54.3 ± 14.6 to 47.6 ± 10.5 mg/dL (P < .001). Weight for patients decreased from 191.2 ± 38.8 to 182.2 ± 36.3 lb (P < .0001). Conclusions This retrospective case series supports the hypothesis that a nutritional purification intervention program emphasizing fruit and vegetable consumption, energy restriction, and nutritional supplements reduces serum lipids and weight.

    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.

    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.

    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.

    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.

    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

    Objective: The objective structured practical examination (OSPE) is a case-based assessment that can be used to assess the clinical reasoning ability of students. The reliability of using an OSPE for this purpose has not been reported in the literature. 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

    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.

    2011-01-01

    Objective The purpose of this case report is to describe the chiropractic management of a patient who had postoperative reconstructive surgery for an anterior cruciate ligament (ACL) tear. Clinical Features A 25-year-old man experienced a rupture of his left ACL, as well as a bucket-handle tear of the medial meniscus and full-thickness tear within the posterior horn of the lateral meniscus, following direct-contact trauma while playing basketball. Intervention and Outcome Postoperative care included a 12-week functional chiropractic rehabilitation program along with Active Release Technique, Graston Technique, and Kinesio Taping. Following treatment, the patient recorded a 0/10 on the Numeric Pain Scale, recorded improvement on the Patient Specific Functional and Pain Scales, returned to play with no complications, and had complete restoration of range of motion and lower extremity muscle strength. At 1-year follow-up, the patient reported no pain and was fully functional. Conclusion A multimodal approach to the treatment of a postsurgical ACL repair was successful in restoring functional ability, as well as complete subjective pain relief. Chiropractic care may be a beneficial addition to the care of postoperative patients. PMID:22027208

    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.

    Background: Faculty scholarship, teaching load, and compensation can be indicators of institutional health and can impact curricular quality. Periodic data are published by the US Department of Education for all sectors of higher education, but do not list chiropractic colleges as a separate category. Objective: To report on the scholarly output, teaching load, and compensation of the full-time faculty at one chiropractic college, and to compare those data to national and local norms. Methods: Data on chiropractic faculty were collected from within the institution. External data were collected from the US Department of Education and US Bureau of Labor Statistics. Results: The chiropractic faculty assessed create about one-tenth the scholarly output, carried 2.7 times the course load of external doctoral faculty and 1.4 times the course load typical of 2-year (community) college faculty, received two-thirds the salary typical for all segments of education, and one-half the typical retirement benefits. Conclusion: Results are suggestive of significant deficiencies within chiropractic education that pose risk to the future of the profession.

    PubMed

    Cyriax, J

    1970-03-01

    Divergent opinions exist on whether or not physiotherapists should manipulate. The controversy can be simply resolved by pointing out that the past policy of withholding such tuition from physiotherapists has in no way diminished the public demand for manipulation; it has merely forced potential patients to the bonesetter. Even those doctors who resent the idea of physiotherapists manipulating must surely prefer its performance by trained personnel working under doctors' guidance to indiscriminate recourse to all sorts of largely untrained laymen without doctors' prior approval. Come what may, the patients are going to be manipulated; at least let this then be sought from trained physiotherapists who give treatment ethically to patients sent to them by doctors.

    Lew, J.Y.; Trudnowski, D.J.; Evans, M.S.; Bennett, D.W.

    1995-02-01

    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 Manipulator Comparative Testing Program compared performance of selected manipulator systems under typical remote handling conditions. The site of testing was the Remote Operations and Maintenance Demonstration Facility operated by the Consolidated Fuel Reprocessing Program of the Oak Ridge National Laboratory. Three experiment examined differences among manipulator systems from the US and Japan. The manipulator systems included the Meidensha BILARM 83A, Central Research Laboratories' (CRL's) Model M-2, and GCA PaR systems Model 6000. Six manipulator and control mode combinations were evaluated: (a) the BILARM in master-slave mode without force reflection; (b) the BILARM in master-slave mode with force reflection; (c) the Model M-2 in master-slave mode without force reflection; (d) the Model M-2 in master-slave mode with force reflection; (e) the BILARM with switchbox controls; and (f) the PaR 6000 with switchbox controls. The experiments also examined differences between master-slave systems with and without force reflections, and differences between master-slave systems and switchbox-controlled systems.

  20. 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.

    Shambaugh, P

    1987-12-01

    This study examines the effects of chiropractic adjustment on the muscles of the back. Vertebrae that are hypomobile may be held in that state by the erector spinae muscle group; adjusting such vertebrae should result in less muscle tension. By measuring the change in electrical activity, such relaxation can be observed. Hypomobile vertebrae were found by motion palpation. The patient was then placed prone and surface electrodes were placed over the upper trapezius, upper erector spinae (T3-T5), and lumbar erector spinae (L1-L3) muscle groups on both sides of the body. The patient was adjusted using full spine toggle recoil thrusts, and postadjustment readings were taken. Results from this study show that significant changes in muscle electrical activity occur as a consequence of adjusting. On average, a 25% reduction in muscle activity was observed across the 20 subjects tested, while no significant reductions were observed with the control group of 14 subjects. Significant reductions in side-to-side imbalances were also observed.

  2. The United States Chiropractic Workforce: An alternative or complement to primary care?

    PubMed Central

    2012-01-01

    Background In the United States (US) a shortage of primary care physicians has become evident. Other health care providers such as chiropractors might help address some of the nation’s primary care needs simply by being located in areas of lesser primary care resources. Therefore, the purpose of this study was to examine the distribution of the chiropractic workforce across the country and compare it to that of primary care physicians. Methods We used nationally representative data to estimate the per 100,000 capita supply of chiropractors and primary care physicians according to the 306 predefined Hospital Referral Regions. Multiple variable Poisson regression was used to examine the influence of population characteristics on the supply of both practitioner-types. Results According to these data, there are 74,623 US chiropractors and the per capita supply of chiropractors varies more than 10-fold across the nation. Chiropractors practice in areas with greater supply of primary care physicians (Pearson’s correlation 0.17, p-value < 0.001) and appear to be more responsive to market conditions (i.e. more heavily influenced by population characteristics) in regards to practice location than primary care physicians. Conclusion These findings suggest that chiropractors practice in areas of greater primary care physician supply. Therefore chiropractors may be functioning in more complementary roles to primary care as opposed to an alternative point of access. PMID:23171540

    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 The attitude towards gender in an educational environment has a significant impact on a student's behavior, sense of well-being, and academic performance. Our study aimed to explore the presence and extent of gender-related issues in a chiropractic undergraduate learning environment, which has been a scarcely researched topic in the literature. Methods The Perceived Chilly Climate Scale (PCCS) was used as the initial tool for screening the gender issues among undergraduates. The issues identified were explored further with a series of focus group interviews. Results The PCCS had an 83% response rate. The PCCS score (105/196) indicated the nonexistence of alarming gender-related issues. However, the PCCS score was significantly higher among female than male subjects, immigrants than nonimmigrants, and minorities than majority ethnic groups. Despite high ratings on the questionnaire quantitative findings, the focus groups indicated a good sense of equality, oppression-free environment, and no obvious signs of discrimination. Conclusion The educational environment of the institution concerned was conducive to equality. However, subtle but important gender-, ethnic-, and minority-related issues could be addressed to provide an enhanced educational environment to learners. PMID:23518905

    Canadians are often confronted with health conditions that impede their lifestyles. To overcome health related limitations individuals often seek assistance from chiropractors or other allied health care professionals. However, despite the recognized benefits of at home exercise programs, patients continue to remain non-compliant to prescribed routines. Non-compliance to home based routines reduces the probability of successful outcome for therapeutic intervention. The advent of the rehabilitation focus in the Chiropractic profession warrants an examination of factors influencing compliance to home exercise prescribed by the chiropractor. The physiological and psychological benefits are well established. If compliance is high, results will typically be positive (i.e. reduced symptoms of pain, reduced anxiety related to condition, and therapeutic goals attained). However, if compliance is low, therapeutic outcomes will often plateau or worse, reverse. Why does non-compliance seem to prevail? The purpose of this paper is to define exercise compliance, identify factors influencing compliance and to suggest intervention strategies that may improve adherence to home-based exercise prescription by chiropractors.

    Objective The purpose of this study is to describe and discuss laboratory tests ordered on elite athletes in an interdisciplinary sports medicine clinic by a doctor of chiropractic over 1 calendar year. Methods A retrospective review of laboratory tests ordered during routine clinical practice as standard screening and diagnostic tests from November 1, 2009, to November 1, 2010 was performed. Data were collected during clinical encounters at one sports medicine clinic and entered into a database for analysis. Descriptive and frequency statistics were used to describe the tests ordered and the frequency of abnormal findings. Results Five hundred and thirty-nine studies were ordered for diagnostic and routine screenings on 137 athlete patients (86 males, 51 females), representing 49 types of tests. Sample sources included blood, urine, skin lesions, and fecal matter. The most commonly ordered tests were complete blood count, comprehensive metabolic panel, serum ferritin, creatine kinase, serum iron and total iron binding capacity, total cortisol, thyroid stimulating hormone, and lipid panels. There were 217 studies (40%) flagged as abnormal by the reporting laboratory. Conclusion This report provides greater insight into the diverse array of laboratory studies ordered over a 1-year period for diagnosis and screening of elite athletes. A high percentage of the results were flagged as abnormal by the laboratory. These findings show that the unique physiology of the elite athlete must be considered when interpreting laboratory findings in this population. PMID:26257590

    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.

    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.

    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.

    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.

    2008-01-01

    Objective Patient satisfaction is important to payers, clinicians, and patients. The concept of satisfaction is multifactorial and measurement is challenging. Our objective was to explore use of a mixed-methods design to examine patient satisfaction with chiropractic care for low back pain. Methods Patients were treated 3 times per week for 3 weeks. Outcomes were collected at Week 3 and Week 4. Qualitative interviews were conducted by the treating clinician and a non-treating staff member. Outcome Measures were the Roland Morris Questionnaire (RMQ), the Visual Analog Scale (VAS), and the Patient Satisfaction Scale (PSS). Interviews were recorded and transcribed, and analyzed for themes and constructs of satisfaction. We compared qualitative interview data with quantitative outcomes, and qualitative data from 2 different interviewers. Results All patients reported high levels of satisfaction. Clinical outcomes were unremarkable with little change noted on VAS and RMQ scores. We categorized patient comments into the same constructs of satisfaction as those identified for the PSS: Quality of Care, Information, Effectiveness, and Caring. An additional construct (Quality of Care) and additional subcategories were identified. Satisfaction with care is not explained by outcome alone. The qualitative data collected from 2 different interviewers had few differences. Conclusion The results of this study suggest that it is feasible to use a mixed-method design to examine patient satisfaction. We were able to refine data collection and analysis procedures for the outcome measures and qualitative interview data. We identified limitations and offer recommendations for the next step: the implementation of a larger study. PMID:18984243

    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. PMID:26109371

    Abstract Objectives The objectives of this study were to determine factors that may affect satisfaction levels of participants in a nonclinic (sport) setting through participant observation and participation. Factors associated with general satisfaction (observed) were determined along with a participant demographic profile, participant knowledge about chiropractic, and satisfaction with treatment received from a chiropractic student. Thereafter, the relationships between the demographic factors, participant knowledge, and participant general satisfaction were determined. Lastly, factors affecting satisfaction levels were compared between the participants and the observers. Methods An exploratory mixed-method observational study that compared results reported by 30 participants and 2 observers, regarding the treatment process, by completion of a self-administered questionnaire. Statistical significance was set at P less than or equal to .05. Results Of the 30 participants, 83.3% were South African, 90% were white, and 63.3% were male, with a mean age of 35.6 years, who reported they were very satisfied with chiropractic care (P = .229). The only factor to produce a significant difference between participants and observers was communication (P = .082 with Spearman = .332). Conclusion In this study, communication had the greatest impact; therefore, it is suggested that positive verbal and nonverbal communication be emphasized in the training of future chiropractic professionals.

    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)

    The free evolution of a non-relativistic charged particle is manipulated using time-dependent magnetic fields. It is shown that the application of a programmed sequence of magnetic pulses can invert the free evolution process, forcing an arbitrary wave packet to 'go back in time' to recover its past shape. The possibility of more general operations upon the Schrodinger wave packet is discussed.

    Abstract Objective The purpose of this study was to determine the feasibility of a chiropractic practice-based research network to investigate the treatment of acute neck pain (ANP) and to report resulting findings. Methods Participating chiropractors recruited sequentially presenting ANP patients on their initial visit to the office. Patients were treated by the chiropractors using their usual methods. Data were prospectively collected by having patients complete the Neck Disability Index, Characteristic Pain Intensity score, and a patient satisfaction questionnaire. Questionnaires were completed during routine office visits at baseline and then at weeks 1, 2, 4, 8, and 26, either in the office or by mail. Results Ten chiropractors supplied data on 99 patients. The number of cases contributed by each of the participating chiropractors ranged from 1 to 54, with a mean (SD) of 9.2 (10.5). Mean (SD) Neck Disability Index scores were 36 (17.9) at baseline and 9.8 (12.2) at the final evaluation; the Characteristic Pain Intensity scores were initially 55.3 (20.4) and were 24.5 (21.5) at the final evaluation. Transient minimal adverse effects were reported by chiropractors for only 7 (7.8%) patients. No serious adverse reactions were reported. Conclusion The practice-based research methodology used in this study appears to be a feasible way to investigate chiropractic care for ANP, and its methodologies could be used to plan future research.

    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

    This paper reports findings of a research study undertaken to determine the attitudes and perceptions of acupuncture, chiropractic, and massage therapy faculty with regard to online learning within their respective disciplines, and to determine how they might be persuaded to teach online. The study surveyed faculty teaching at schools in these three fields and followed up with additional interviews. The study results indicate that, in general, acupuncture, chiropractic, and massage therapy faculty lack awareness of the capabilities of online education and the elements of good online learning. There is also a perception that what they teach cannot be taught online because of its kinesthetic requirements. The faculty hold this perception in spite of the success of medical science and related health care fields in the online environment, and they do not seem to separate the kinesthetic from the didactic. The present study indicates that faculty opinions about online instruction in this alternative type of education range from being willing to look at the potential of online education to outright dismissing it.

    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.

  9. 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

  10. A survey of accessibility and utilisation of chiropractic services for wheelchair-users in the United Kingdom: What are the issues?

    2011-01-01

    Background People with physical disabilities experience barriers to healthcare across all services despite a legal and moral obligation to the contrary. Complementary medicine is considered as supplementary to conventional care and integration of these approaches is essential to achieve optimal care. This paper explores the utilisation of chiropractic services and practitioner experiences of treating wheelchair-users which appears under-reported. Methods A 20 item questionnaire was posted to 250 randomly selected chiropractors registered with the General Chiropractic Council. Follow-up questionnaires were sent 7 days after the initial return date. Quantitative data were subjected to frequency analysis. Results The response rate was 64% (n = 161). The majority (66%) of chiropractors had been in practice less than 10 years and were practice owners (50%). Fifty-two percent of chiropractors sampled had treated a patient in a wheelchair in the previous 5 years. The majority (87%) had treated between 1 and 5 such patients. Patients with multiple sclerosis, stroke and cerebral palsy most commonly presented for treatment. The majority of patients' presenting complaint was musculoskeletal in origin, primarily for pain control. Only 13% of respondents worked in a fully accessible clinic. Impracticality of alterations was the most common reason for inaccessibility. Conclusions Wheelchair-users seem to be an underserved patient group in relation to chiropractic services. Chiropractic management is primarily utilised for pain control in patients with physical disabilities in which mobility may be improved or maintained. Co-management of wheelchair-users with GPs appears to be desirable in order to achieve optimal patient care however more research is required regarding the efficacy of chiropractic treatment for a range of disabling conditions. Physical access was identified as a key barrier to accessing care. PMID:21914167

    Objective The purpose of this case series is to report the effects of manipulation under anesthesia (MUA) for patients with lumbopelvic (lumbar spine, sacroiliac and/or pelvic, hip) pain in an outpatient ambulatory/hospital-based setting. Methods A retrospective chart review of cases treated at an outpatient ambulatory surgical center in New York and a general hospital in New York was performed. Patients with pre- and postintervention Oswestry Low Back Pain Disability Index (ODI) scores and lumbopelvic and hip complaints were included (N = 18). No intervention other than MUA was administered between the initial and follow-up ODI scoring. Scores on the ODI were assessed within 1 week prior to MUA and again within 2 weeks postprocedure. Results Patients underwent 2 to 4 chiropractic MUA procedures over the course of 7 to 8 days as per National Academy of Manipulation Under Anesthesia physicians' protocols. Preprocedure ODI scores ranged from 38 to 76, with an average score of 53.4. Postprocedure scores ranged from 0 to 66, with an average score of 32.8. For each patient, ODI scores were lower after MUA, with an average decrease of 20.6. Sixteen of 18 patients experienced a clinically meaningful improvement in ODI score. No adverse reactions were reported. Conclusions For 16 of the 18 patients with chronic lumbopelvic pain reported in this study, MUA showed clinically meaningful reduction in low back pain disability.

    Single-molecule manipulation studies open a door for a close-up investigation of complex biological interactions at the molecular level. In these studies, single biomolecules are pulled while their force response is being monitored. The process is often nonequilibrium, and interpretation of the results has been challenging. We used the atomic force microscope to pull proteins and DNA, and determined the equilibrium properties of the molecules using the recently derived nonequilibrium work theorem. I will present applications of the technique in areas ranging from fundamental biological problems such as DNA mechanics, to complex medical processes such as the mechanical activation of von Willebrand Factor, a key protein in blood coagulation.

    Biochemical gradients convey information through space, time, and concentration, and are ultimately capable of spatially resolving distinct cellular phenotypes, such as differentiation, proliferation, and migration. How these gradients develop, evolve, and function during development, homeostasis, and various disease states is a subject of intense interest across a variety of disciplines. Microfluidic technologies have become essential tools for investigating gradient sensing in vitro due to their ability to precisely manipulate fluids on demand in well-controlled environments at cellular length scales. This review will highlight their utility for studying gradient sensing along with relevant applications to biology. PMID:25905100

    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.

  15. 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

    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

    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.

    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.

    Agrobacterium species are plant-associated relatives of the rhizobia. Several species cause plant diseases such as crown gall and hairy root, although there are also avirulent species. A. tumefaciens is the most intensively studied species and causes crown gall, a neoplastic disease that occurs on a variety of plants. Virulence is specified by large plasmids, and in the case of A. tumefaciens, this is called the Ti (tumor-inducing) plasmid. During pathogenesis virulent agrobacteria copy a segment of the Ti plasmid and transfer it to the plant, where it subsequently integrates into the plant genome, and expresses genes that result in the disease symptoms. A. tumefaciens has been used extensively as a plant genetic engineering tool and is also a model microorganism that has been well studied for host-microbe associations, horizontal gene transfer, cell-cell communication, and biofilm formation. This unit describes standard protocols for genetic manipulation of A. tumefaciens. PMID:22549163

    1987-01-01

    The author presents a novel approach to adaptive control of manipulators to achieve trajectory tracking by the joint angles. The central concept in this approach is the utilization of the manipulator inverse as a feedforward controller. The desired trajectory is applied as an input to the feedforward controller which behaves as the inverse of the manipulator at any operating point; the controller output is used as the driving torque for the manipulator. The controller gains are then updated by an adaptation algorithm derived from MRAC (model reference adaptive control) theory to cope with variations in the manipulator inverse due to changes of the operating point. An adaptive feedback controller and an auxiliary signal are also used to enhance closed-loop stability and to achieve faster adaptation. The proposed control scheme is computationally fast and does not require a priori knowledge of the complex dynamic model or the parameter values of the manipulator or the payload.

    Summary of background data Cervical spine injuries sustained in rear-end crashes cost at least $7 billion in insurance claims annually in the United States alone. When positioned correctly, head restraint systems have been proven effective in reducing the risk of whiplash associated disorders. Chiropractors should be knowledgeable about the correct use of head restraint systems to educate their patients and thereby prevent or minimize such injuries. Objectives The primary objective of this study was to determine the prevalence of correct positioning of car seat head restraints among the interns at our institution. The secondary objective was to determine the same chiropractic interns’ knowledge of the correct positioning of car seat head restraints. It was hypothesized that 100 percent of interns would have their head restraint correctly positioned within an acceptable range and that all interns would possess the knowledge to instruct patients in the correct positioning of head restraints. Study Design Cross-sectional study of a convenient sample of 30 chiropractic interns from one institution. Methods Interns driving into the parking lot of our health center were asked to volunteer to have measurements taken and to complete a survey. Vertical and horizontal positions of the head restraint were measured using a beam compass. A survey was administered to determine knowledge of correct head restraint position. The results were recorded, entered into a spreadsheet, and analyzed. Results 13.3 percent of subjects knew the recommended vertical distance and only 20 percent of subjects knew the recommended horizontal distance. Chi Square analyses substantiated that the majority of subjects were unaware of guidelines set forth by the National Highway Traffic Safety Administration (NHTSA) for the correct positioning of the head restraint (χ2vertical = 16.13, χ2horizontal = 10.80, p <.05). Only 6.7 percent of the subjects positioned their head restraint at the vertical

    Purpose: Organic chemistry has been shown to correlate with academic success in the preclinical years of medicine, dentistry, and graduate physiology. The purpose of this study is to examine the relationship between undergraduate organic chemistry grades and first-semester biochemistry grades at a Midwest chiropractic doctoral program. Methods: Students enrolled in a first-semester biochemistry course who had completed the prerequisite courses in organic chemistry offered at this same institution were entered into the study. The total grade for each of the three courses was calculated using the midterm and final exam raw scores with a weighting of 50% each. Analysis consisted of obtaining correlation coefficients between the total grades of organic 1 with biochemistry and organic 2 with biochemistry. Using the biochemistry total grade, the students were divided into quartiles and course grades for both organic chemistry 1 and 2 were calculated. Results: For the 109 students in the study, the correlation coefficient between the biochemistry and organic chemistry 1 and biochemistry and organic chemistry 2 courses was r = 0.744 and r = 0.725, respectively. The difference in organic chemistry grades between those in the first and fourth quartiles was 63.2% and 86.9% for organic chemistry 1 (p < .001) and 60.9% and 79.4% for organic chemistry 2 (p < .001). Conclusion: This study shows that organic chemistry can be used as an indicator of future academic success in a chiropractic biochemistry course. Knowledge of such a relationship could prove useful to identify students who may potentially run into academic difficulty with first-year biochemistry PMID:20480012

    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

    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.

    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

    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

    Ghimire, Anil

    This dissertation describes progress made towards the control of emission direction and polarization from a single emitter using a sharp gold-coated atomic force microscope tip. When a metallic tip is scanned in the emitter near-field, the probe acts as a secondary emitter such that the superposition of electromagnetic fields from these two emitters modifies the emission polarization and pattern in the far-field. The physical mechanism underlying this ability to manipulate the emission polarization and direction is studied in detail using a unique data acquisition technique and finite-difference time domain (FDTD) simulations. This technique enables us to reveal how the polarization of emitted photons from a quantum dot (QD) is modified as a gold-coated tip is scanned laterally and vertically in its proximity, and the FDTD simulations are used to calculate the angular emission pattern. The simulated emission pattern at the back-focal plane enables us to identify how the direction of emitted photons is altered as the gold tip is scanned in the proximity of a dipole emitter. This dissertation also highlights a novel back-focal imaging technique correlated with the vertically oscillating probe. By pulsing the continuous-wave laser at various phases of tip oscillation and using the near-field interaction of the tip-sample, the exact tip-sample distance can be identified. Tip-induced modification of the angular emission pattern from an individual quantum dot is experimentally demonstrated. This work also includes the study of the emission properties of GaN nanowires. A hyper-spectral imaging technique combined with spectral center of mass (SCOM) analysis helps us to identify the spectral inhomogeneity within a nanowire. The spectral information within a diffraction-limited spot of a nanowire provides the insight regarding the distribution of mid-gap defect states within a nanowire.

    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

  1. Direct Manipulation in Virtual Reality

    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.

  2. 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

    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

    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

  5. Manipulability and object recognition: is manipulability a semantic feature?

    Several lines of evidence exist, coming from neuropsychology, neuroimaging and behavioural investigations on healthy subjects, suggesting that an interaction might exist between the systems devoted to object identification and those devoted to online object-directed actions and that the way an object is acted upon (manipulability) might indeed influence object recognition. In this series of experiments on speeded word-to-picture-matching tasks, it is shown how the presentation of pairs of objects sharing similar manipulation causes greater interference with respect to objects sharing only visual similarity (experiment 1). Moreover, (experiment 2) it is shown how the repeated presentation of pairs of objects sharing a similar type of manipulation leads to a 'negative' serial position effect, with the number of errors increasing across presentations, a behaviour that is typically found in patients with access deficits to semantic representations. By contrast, the repeated presentation of pairs of objects sharing only visual similarity leads to an opposite 'positive' serial position effect, with errors decreasing across presentations. It is argued that a negative serial position effect is linked to interference occurring within the semantic system, and therefore that the way an object is manipulated is indeed a semantic feature, critical in defining manipulable object properties at a semantic level. To our knowledge, this constitutes the first direct evidence of manipulability being a semantic dimension. The results are discussed in the light of current models of semantic memory organization.

    Trajectory planning and implementation forms a substantial part of current and future orthopaedic practice. This type of surgery is governed by a basic orthopaedic principle [1] which involves the placement of a surgical tool at a specific site within a region, via a trajectory which is planned from X-ray based 2D images and governed by 3D anatomical constraints. The accuracy and safety of procedures utilising the basic orthopaedic principle depends on the surgeon's judgement, experience, ability to integrate images, utilisation of intra-operative X-ray, knowledge of anatomical-biomechanical constraints and eye hand dexterity. The surgeon must remain as the responsible medical expert in charge of the overall system. At the same time the surgeon covets the accuracy offered by Computer Assisted Surgery including a manipulator. A summary of current inadequacies of manipulators indicates that the main drivers for future work are that accuracy is critical in close contact with the environment, safety concerns dictate manipulator geometry and technological limitations are many. In any effort to develop an optimal manipulator to guide surgical instruments and tools it is an obvious first step to review and categorise current manipulators. The aim of this paper is to review all aspects of manipulator design against the five main criteria of ergonomics; safety; accuracy; sterility and measurable benefits such as reduced operative time, reduced surgical trauma and improved clinical results.

    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

    Objective : Doctors of chiropractic (DCs) use manual cervical distraction to treat patients with neck pain. Previous research demonstrates variability in traction forces generated by different DCs. This article reports on a training protocol and monthly certification process using bioengineering technology to standardize cervical traction force delivery among clinicians. Methods : This longitudinal observational study evaluated a training and certification process for DCs who provided force-based manual cervical distraction during a randomized clinical trial. The DCs completed a 7-week initial training that included instructional lectures, observation, and guided practice by a clinical expert, followed by 3 hours of weekly practice sessions delivering the technique to asymptomatic volunteers who served as simulated patients. An instrument-modified table and computer software provided the DCs with real-time audible and visual feedback on the traction forces they generated and graphical displays of the magnitude of traction forces as a function of time immediately after the delivery of the treatment. The DCs completed monthly certifications on traction force delivery throughout the trial. Descriptive accounts of certification attempts are provided. Results : Two DCs achieved certification in traction force delivery over 10 consecutive months. No certification required more than 3 attempts at C5 and occiput contacts for 3 force ranges (0-20 N, 21-50 N, and 51-100 N). Conclusions : This study demonstrates the feasibility of a training protocol and certification process using bioengineering technology for training DCs to deliver manual cervical distraction within specified traction force ranges over a 10-month period.

    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

    A high precision redundant robotic manipulator for overcoming contents imposed by obstacles or imposed by a highly congested work space is disclosed. One embodiment of the manipulator has four degrees of freedom and another embodiment has seven degrees of freedom. Each of the embodiments utilize a first selective compliant assembly robot arm (SCARA) configuration to provide high stiffness in the vertical plane, a second SCARA configuration to provide high stiffness in the horizontal plane. The seven degree of freedom embodiment also utilizes kinematic redundancy to provide the capability of avoiding obstacles that lie between the base of the manipulator and the end effector or link of the manipulator. These additional three degrees of freedom are added at the wrist link of the manipulator to provide pitch, yaw and roll. The seven degrees of freedom embodiment uses one revolute point per degree of freedom. For each of the revolute joints, a harmonic gear coupled to an electric motor is introduced, and together with properly designed based servo controllers provide an end point repeatability of less than 10 microns. 3 figs.

    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.

    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.

  18. 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.

    The ability to manipulate small particles suspended in fluids has many practical applications, ranging from the mechanical testing of macromolecules like DNA to the controlled abrasion of brittle surfaces for precision polishing. A natural method is non-contact manipulation of particles through boundary excitations. Particle-manipulation via a vibrating cilia to establish controlled fluid flows with desired patterns of transport is one such bioinspired method. We show experimental results on the clustering and transport of finite-sized particles in the streaming flow set up by the oscillating cilia. We further show computations to explain the effects of hyperbolic structures in the four dimensional phase space of the dynamics of finite-sized particles.

    Nonverbal visual cues accompany speech to supplement the meaning of spoken words, signify emotional state, indicate position in discourse, and provide back-channel feedback. This visual information includes head movements, facial expressions and body gestures. In this article we describe techniques for manipulating both verbal and nonverbal facial gestures in video sequences of people engaged in conversation. We are developing a system for use in psychological experiments, where the effects of manipulating individual components of nonverbal visual behavior during live face-to-face conversation can be studied. In particular, the techniques we describe operate in real-time at video frame-rate and the manipulation can be applied so both participants in a conversation are kept blind to the experimental conditions.

    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. PMID:24088151

    The sexually transmitted pathogen, Neisseria gonorrhoeae, undergoes natural transformation at high frequency. This property has led to the rapid dissemination of antibiotic resistance markers and to the panmictic structure of the gonococcal population. However, high-frequency transformation also makes N. gonorrhoeae one of the easiest bacterial species to manipulate genetically in the laboratory. Techniques have been developed that result in transformation frequencies >50%, allowing the identification of mutants by screening and without selection. Constructs have been created to take advantage of this high-frequency transformation, facilitating genetic mutation, complementation, and heterologous gene expression. Techniques are described for genetic manipulation of N. gonorrhoeae, as well as for growth of this fastidious organism.

    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.

    For many years, experience has been accumulated on embryo and gamete manipulation in livestock animals. The present work is a review of these techniques and their possible application in human embryology in specific cases. It is possible to manipulate gametes at different levels, producing paternal or maternal haploid embryos (hemicloning), using different techniques including nuclear transfer. At the embryonic stage, considering practical, ethical and legal issues, techniques will be reviewed that include cloning and embryo splitting at the cleavage stage, morula, or blastocyst stage.

    In this paper, we propose a learning control scheme for direct trajectory control of robotic manipulators. The main features are that we use a priori structure knowledge of robot dynamics in the design and the neural networks are not used to learn inverse dynamic models. The neural network controller is utilized to compensate the deviation due to the approximate models of robotic manipulators. In addition, true teaching signals of the neural network compensators are employed in the learning phase. Simulations are conducted to show the feasibility of the proposed method.

    2011-01-01

    Objective To characterize the types of control procedures used in controlled clinical trials of cervical spine manipulation and to evaluate the outcomes obtained by subjects in control groups so as to improve the quality of future clinical trials Methods A search of relevant clinical trials was performed in PubMed 1966-May 2010 with the following key words: "Chiropractic"[Mesh] OR "Manipulation, Spinal"[Mesh]) AND "Clinical Trial "[Publication Type]. Reference lists from these trials were searched for any additional trials. The reference lists of two prior studies, one review and one original study were also searched. Accepted reports were then rated for quality by 2 reviewers using the PEDro scale. Studies achieving a score of >50% were included for data extraction and analysis. Intra-group change scores on pain outcomes were obtained. For determining clinically important outcomes, a threshold of 20% improvement was used where continuous data were available; otherwise, an effect size of 0.30 was employed Results The PubMed search yielded 753 citations of which 13 were selected. Eight (8) other studies were identified by reviewing two systematic reviews and through reference searches. All studies scored >50% on the PEDro scale. There were 9 multi-session studies and 12 single-session studies. The most commonly used control procedure was "manual contact/no thrust". Four (4) studies used a placebo-control (patient blinded). For two of these studies with VAS data, the average change reported was 4.5 mm. For the other control procedures, variable results were obtained. No clinically important changes were reported in 57% of the paired comparisons, while, in 43% of these, changes which would be considered clinically important were obtained in the control groups. Only 15% of trials reported on post-intervention group registration. Conclusions Most control procedures in cervical manipulation trials result in small clinical changes, although larger changes are observed in

    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

    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.

    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.

    Objective : Doctors of chiropractic (DCs) use manual cervical distraction to treat patients with neck pain. Previous research demonstrates variability in traction forces generated by different DCs. This article reports on a training protocol and monthly certification process using bioengineering technology to standardize cervical traction force delivery among clinicians. Methods : This longitudinal observational study evaluated a training and certification process for DCs who provided force-based manual cervical distraction during a randomized clinical trial. The DCs completed a 7-week initial training that included instructional lectures, observation, and guided practice by a clinical expert, followed by 3 hours of weekly practice sessions delivering the technique to asymptomatic volunteers who served as simulated patients. An instrument-modified table and computer software provided the DCs with real-time audible and visual feedback on the traction forces they generated and graphical displays of the magnitude of traction forces as a function of time immediately after the delivery of the treatment. The DCs completed monthly certifications on traction force delivery throughout the trial. Descriptive accounts of certification attempts are provided. Results : Two DCs achieved certification in traction force delivery over 10 consecutive months. No certification required more than 3 attempts at C5 and occiput contacts for 3 force ranges (0-20 N, 21-50 N, and 51-100 N). Conclusions : This study demonstrates the feasibility of a training protocol and certification process using bioengineering technology for training DCs to deliver manual cervical distraction within specified traction force ranges over a 10-month period.

    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: 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

    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.

  9. An evolutionary resolution of manipulation conflict.

    PubMed

    González-Forero, Mauricio

    2014-07-01

    Individuals can manipulate the behavior of social partners. However, manipulation may conflict with the fitness interests of the manipulated individuals. Manipulated individuals can then be favored to resist manipulation, possibly reducing or eliminating the manipulated behavior in the long run. I use a mathematical model to show that conflicts where manipulation and resistance coevolve can disappear as a result of the coevolutionary process. I find that while manipulated individuals are selected to resist, they can simultaneously be favored to express the manipulated behavior at higher efficiency (i.e., providing increasing fitness effects to recipients of the manipulated behavior). Efficiency can increase to a point at which selection for resistance disappears. This process yields an efficient social behavior that is induced by social partners, and over which the inducing and induced individuals are no longer in conflict. A necessary factor is costly inefficiency. I develop the model to address the evolution of advanced eusociality via maternal manipulation (AEMM). The model predicts AEMM to be particularly likely in taxa with ancestrally imperfect resistance to maternal manipulation. Costly inefficiency occurs if the cost of delayed dispersal is larger than the benefit of exploiting the maternal patch. I discuss broader implications of the process.

    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 pipe manipulator is a developing mechatronic system to enhance productivity and protects workers from cave-ins in the trench while excavating and laying pipe. The pipe manipulator is for installing concrete pipe into the trench. It is an optical-electro-mechanical system. The mechanism is make up of two parts, the upside and underside. The upside is for lifting the equipment by backhoe and rotating the underside mechanism. It includes rigidity lift beams, holding pad, four-bar linkages, hydraulic cylinder, rotating support, and rotating mechanism. Holding pad will press the bucket back to keep the bucket hooking the pipe man safely and stably. The underside mechanism is for lifting, holding and adjusting the pipe section's stance. The underside mechanism includes support trolley, and lift fork. The support trolley is driven by hydraulic cylinder for moving the fork forward or backward while laying a pipe into trench. The fork is with a self-lock mechanism for preventing the pipe from slide out of the prongs. A new photoelectric locating system is developed for auto-measuring the installing pipe section's stance within the work area. The laser target has been developed as a key part in the photoelectric locating systems. The photoelectric target is a rotating polar coordinate. Photodiodes are used for making the polar radius. There is an angular displacement sensor sitting on the heart-axis of the target for measuring angle of the target rotating. The pipe manipulator can be located by the system, and the locating methods have been presented at last of the paper.

    As part of the Modular Intelligent Manipulation system with Intuitive Control program, industry is working with the U.S. Army to explore technologies that will allow a user to intuitively control multiple degree of freedom robotic arms and maintain better awareness of the operating environment through haptic feedback. In addition to reporting resistance, haptic feedback can help make operators feel like they are actually there with the robot, opening doors, unscrewing blast caps, cutting wires, or removing batteries. Coupled with intuitive controls and advanced video feedback, the goal of this project is to provide users with the sensation that the robot is an extension of their body, all from a safe distance.

    1994-01-01

    Algorithm for improved control of underactuated multiple-link robotic manipulators developed via spatial-algebra-operator approach. Aspects of this approach described in several previous articles in NASA Tech Briefs-most recently "Robot Control Based on Spatial-Operator Algebra" (NPO-17918). Underactuated manipulator has fewer actuators than it has degrees of freedom. Complexity of underactuated systems managed by unified analysis. It has implications for fault-tolerant control, and many practical manipulators underactuated. Examples include manipulators with flexible joints and/or flexible links; space/underwater robots; manipulators that operate with some actuators that turned off because of failure or because of need to conserve energy; manipulators that grasp objects loosely, and manipulators that grasp objects with internal degrees of freedom (e.g., plungers, rollers).

  19. Symbolic manipulation and transport benchmarks

    The establishment of reliable benchmark solutions is an integral part of the development of computational algorithms to solve the Boltzmann equation of particle motion. These solutions provide standards by which code developers can assess new numerical algorithms as well as ensure proper programming. A transport benchmark solution, as defined here, is the accurate numerical evaluation (3 to 5 digits) of an analytical solution to the transport equation. The basic elements of such a solution are an analytical representation free from discretization and a numerical evaluation for which an error estimate can be obtained. Symbolic manipulation software such as REDUCE, MACSYMA, and SMP can greatly aid in the generation of benchmark solutions. The benefit of these manipulators lies both in their ability to perform lengthy algebraic calculations and to write a code that can be incorporated directly into existing programs. Using two fundamental problems from particle transport theory, the author explores the advantages and limitations of the application of the REDUCE software package in generating time dependent benchmark solutions.

  20. Actuators for a space manipulator

    1987-01-01

    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.

    The discovery of the third domain of life, the Archaea, is one of the most exciting findings of the last century. These remarkable prokaryotes are well known for their adaptations to extreme environments; however, Archaea have also conquered moderate environments. Many of the archaeal biochemical processes, such as methane production, are unique in nature and therefore of great scientific interest. Although formerly restricted to biochemical and physiological studies, sophisticated systems for genetic manipulation have been developed during the last two decades for methanogenic archaea, halophilic archaea and thermophilic, sulfur-metabolizing archaea. The availability of these tools has allowed for more complete studies of archaeal physiology and metabolism and most importantly provides the basis for the investigation of gene expression, regulation and function. In this review we provide an overview of methods for genetic manipulation of Methanosarcina spp., a group of methanogenic archaea that are key players in the global carbon cycle and which can be found in a variety of anaerobic environments.

    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.

    1992-01-01

    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.

    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.

    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.

  6. The rationale for primary spine care employing biopsychosocial, stratified and diagnosis-based care-pathways at a chiropractic college public clinic: a literature review

    PubMed Central

    2013-01-01

    Current management practices for low back pain have led to rising costs without evidence of improvement in the quality of care. Low back pain remains a diagnostic and management challenge for practitioners of many types and is now thought to be a leading global cause of disability. Beyond many published clinical practice guidelines, there are emerging, evidence-based care-pathways including stratification according to the patient's prognosis, classification-based management, diagnosis-based clinical decision guides and biopsychosocial models of care. A proposed solution for successfully addressing low back pain is to train residents at a chiropractic college public clinic to function as primary spine care practitioners, employing evidence-based care-pathways. The rationale for such is described with expected benefits to patient care, improved financial health of medical delivery systems and the training of chiropractors to successfully fill a niche in the healthcare system.

    Objective This commentary discusses the evolving sociocultural roles and sociocultural authority of chiropractic. Discussion The complex interconnectivity of the biological, psychological, and social aspects of our individual and collective well-being has occupied centuries of “nature versus nurture” philosophical debate, creative art, and scientific work. What has emerged is a better understanding of how our human development is affected by the circumstances of what we are born with (ie, nature) and how we are shaped by the circumstances that we are born into (ie, nurture). Conclusion In the new millennium, a cumulative challenge to the emerging integrative biopsychosocial health care disciplines is one of reconciling “circumstance versus choice”; that is, advancing individually and collectively the fullest actualization of human potential through the philosophy, art, and science of autonomy and empowerment.

  8. The provision of chiropractic, physiotherapy and osteopathic services within the Australian private health-care system: a report of recent trends

    PubMed Central

    2014-01-01

    Background Chiropractors, physiotherapists, and osteopaths receive training in the diagnosis and management of musculoskeletal conditions. As a result there is considerable overlap in the types of conditions that are encountered clinically by these practitioners. In Australia, the majority of benefits paid for these services come from the private sector. The purpose of this article is to quantify and describe the development in service utilization and the cost of benefits paid to users of these healthcare services by private health insurers. An exploration of the factors that may have influenced the observed trends is also presented. Methods A review of data from the Australian Bureau of Statistics, Australian Health Practitioner Regulation Agency, and the Australian Government Private Health Insurance Administration Council was conducted. An analysis of chiropractic, physiotherapy and osteopathic service utilisation and cost of service utilisation trend was performed along with the level of benefits and services over time. Results In 2012, the number of physiotherapists working in the private sector was 2.9 times larger than that of chiropractic, and 7.8 times that of the osteopathic profession. The total number of services provided by chiropractors, physiotherapists, and osteopaths increased steadily over the past 15 years. For the majority of this period, chiropractors provided more services than the other two professions. The average number of services provided by chiropractors was approximately two and a half times that of physiotherapists and four and a half times that of osteopaths. Conclusions This study highlights a clear disparity in the average number of services provided by chiropractors, physiotherapists, and osteopaths in the private sector in Australia over the last 15 years. Further research is required to explain these observed differences and to determine whether a similar trend exists in patients who do not have private health insurance cover

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

    PubMed Central

    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

    1989-01-01

    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.

    Stenotrophomonas maltophilia is a Gram-negative, aerobic, motile, environmental bacterium that is emerging as an important nosocomial pathogen (Brooke, 2012; Looney, Narita, & Mühlemann, 2009) with high rates of attributable mortality in severely ill patients (Falagas et al., 2009; Paez & Costa, 2008; Sattler, Mason, & Kaplan, 2000; Senol, DesJardin, Stark, Barefoot, & Snydman, 2002; Weber et al., 2007). S. maltophilia is of particular concern to patients suffering from cystic fibrosis (CF) as it has been shown to colonize airway epithelial and establish a chronic infection (Goncalves-Vidigal et al., 2011). Here we describe several molecular techniques for the genetic manipulation of this bacterium, including DNA extraction, RNA extraction, conjugation of plasmids from E. coli and allelic exchange.

    A generalized precompiler for systems performing algebraic manipulation of Poisson series has been written. It accepts a trigonometric superset of FORTRAN IV similar to Jefferys' TRIGRUN language (Jefferys, 1972) and generates a valid FORTRAN IV program which drives an abstract formula manipulation machine. This machine is designed to be generally compatible with any manipulation system, and has been implemented with two such systems. The precompiler is written in standard FORTRAN IV and was designed to allow simple conversion for use on most computers.

    This paper proposes a bracing strategy for micro/macro manipulators. The bracing micro/macro manipulator can provide advantages in accurate positioning, large work-space, and contact-task capability however, in exchange for improvement in performance one must accept the complex control problem along wit the complex dynamics. This research develops a control scheme for a bracing manipulator which makes multiple contacts with the environment. Experimental results show the feasibility of the proposed ideas for real world applications.

    2015-01-01

    Background: There appears to be very little in the research literature on the safety of thrust joint manipulation (TJM) when applied to the thoracic spine. Purpose: To retrospectively analyze all available documented case reports in the literature describing patients who had experienced severe adverse events (AE) after receiving TJM to their thoracic spine. Data Sources: Case reports published in peer reviewed journals were searched in Medline (using Ovid Technologies, Inc.), Science Direct, Web of Science, PEDro (Physiotherapy Evidence Database), Index of Chiropractic literature, AMED (Allied and Alternative Medicine Database), PubMed and the Cumulative Index to Nursing and Allied Health (CINHAL) from January 1950 to February 2015. Study Selection: Case reports were included if they: (1) were peer-reviewed; (2) were published between 1950 and 2015; (3) provided case reports or case series; and (4) had TJM as an intervention. Articles were excluded if: (1) the AE occurred without TJM (e.g. spontaneous); (2) the article was a systematic or literature review; or (3) it was written in a language other than English or Spanish. Data Extraction: Data extracted from each case report included: gender; age; who performed the TJM and why; presence of contraindications; the number of manipulation interventions performed; initial symptoms experienced after the TJM; as well as type of severe AE that resulted. Results: Ten cases, reported in 7 case reports, were reviewed. Cases involved females (8) more than males (2), with mean age being 43.5 years (SD=18.73, Range = 17 -71). The most frequent AE reported was injury (mechanical or vascular) to the spinal cord (7/10), with pneumothorax and hematothorax (2/10) and CSF leak secondary to dural sleeve injury (1/10). Limitations: There were only a small number of case reports published in the literature and there may have been discrepancies between what was reported and what actually occurred, since physicians dealing with the

    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

  18. Research on reconfigurable and reliable manipulators

    NASA Astrophysics Data System (ADS)

    Khosla, P. K.; Kanade, T.

    We have proposed the concept of reconfigurable manipulators as a solution to tasks that require varied configurations of manipulators. Using modules of varying sizes and performance specifications, it is possible to build manipulators to suit the task at hand. Our research is not only addressing the issue of creating such manipulators but also the interesting theoretical challenges posed in mapping tasks to manipulators. We have developed strategies that allow us to determine the kinematic and dynamic configuration of a non-redundant manipulator from task specifications such as reachability, obstacle avoidance, manipulability, joint, limits, and joint velocities and accelerations. We are presently extending this design methodology for design of redundant and fault tolerant manipulator systems. Further, we are also addressing issues in automatic generation of software for kinematics, dynamics, and controllers for the configured manipulators. During the next year, we will be demonstrating automatic generation of software on the prototype system that we are building. We expect to have 4 joint and link modules available for this demonstration. The joint and link modules will also incorporate concepts for making power and data connections when the mechanical connection is made. Further, they will also include electronics, housed within the module, for communication and real-time control.

    The performance of an orbital teleoperator system which includes small dextrous servicing manipulators to be used in satellite servicing was examined. System/operator performance testing was implemented and the results of a fine positioning control test using two different manipulator systems varying widely in manipulator configuration and control systems are presented. Fine position control is viewed as representing a fundamental requirement placed on manipulator control. The relationship of position control to more complex tasks which directly represent on-orbit servicing operations are also presented.

  20. 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

    2009-11-01

    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.

    2015-01-01

    Significant inter- and intraspecific genetic variation exists in duckweed, thus the potential for genome plasticity and manipulation is high. Polyploidy is recognised as a major mechanism of adaptation and speciation in plants. We produced several genome-duplicated lines of Landoltia punctata (Spirodela oligorrhiza) from both whole plants and regenerating explants using a colchicine-based cocktail. These lines stably maintained an enlarged frond and root morphology. DNA ploidy levels determined by florescence-activated cell sorting indicated genome duplication. Line A4 was analysed after 75 biomass doublings. Frond area, fresh and dry weights, rhizoid number and length were significantly increased versus wild type, while the growth rate was unchanged. This resulted in accumulation of biomass 17-20% faster in the A4 plants. We sought to determine if specific differences in gene products are found in the genome duplicated lines. Non-targeted ultra performance LC-quadrupole time of flight mass spectrometry was employed to compare some of the lines and the wild type to seek identification of up-regulated metabolites. We putatively identified differential metabolites in Line A65 as caffeoyl hexoses. The combination of directed genome duplication and metabolic profiling might offer a path for producing stable gene expression, leading to altered production of secondary metabolites. PMID:25040392

    2012-05-01

    The distribution of nutrients and assimilates in different organs and tissues is in a constant state of flux throughout the growth and development of a plant. At key stages during the life cycle profound changes occur, and perhaps one of the most critical of these is during seed filling. By restricting the competition for reserves in Arabidopsis plants, the ability to manipulate seed size, seed weight, or seed content has been explored. Removal of secondary inflorescences and lateral branches resulted in a stimulation of elongation of the primary inflorescence and an increase in the distance between siliques. The pruning treatment also led to the development of longer and larger siliques that contained fewer, bigger seeds. This seems to be a consequence of a reduction in the number of ovules that develop and an increase in the fatty acid content of the seeds that mature. The data show that shoot architecture could have a substantial impact on the partitioning of reserves between vegetative and reproductive tissues and could be an important trait for selection in rapid phenotyping screens to optimize crop performance.

    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.

    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. PMID:23793156

    Significant inter- and intraspecific genetic variation exists in duckweed, thus the potential for genome plasticity and manipulation is high. Polyploidy is recognised as a major mechanism of adaptation and speciation in plants. We produced several genome-duplicated lines of Landoltia punctata (Spirodela oligorrhiza) from both whole plants and regenerating explants using a colchicine-based cocktail. These lines stably maintained an enlarged frond and root morphology. DNA ploidy levels determined by florescence-activated cell sorting indicated genome duplication. Line A4 was analysed after 75 biomass doublings. Frond area, fresh and dry weights, rhizoid number and length were significantly increased versus wild type, while the growth rate was unchanged. This resulted in accumulation of biomass 17-20% faster in the A4 plants. We sought to determine if specific differences in gene products are found in the genome duplicated lines. Non-targeted ultra performance LC-quadrupole time of flight mass spectrometry was employed to compare some of the lines and the wild type to seek identification of up-regulated metabolites. We putatively identified differential metabolites in Line A65 as caffeoyl hexoses. The combination of directed genome duplication and metabolic profiling might offer a path for producing stable gene expression, leading to altered production of secondary metabolites.

    Pacific Northwest Laboratory (PNL) has developed a manipulator workcell to load and unload nuclear weapon pit assemblies from a cart. To develop this workcell, PNL procured a commercially available manipulator, equipped it with force-sensing and vision equipment, and developed manipulator control software. Manipulator workcell development demonstrated that commercially available manipulator systems can successfully perform this task if the appropriate manipulator is selected and the manipulator workcell tooling and software are carefully designed.

    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

  13. Fuzzy logic control of telerobot manipulators

    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.

  14. 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

    Huang, Jen-Kuang; Yang, Li-Farn

    1988-01-01

    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 within the inertia matrix. Then a feedback 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.

  16. Dynamically consistent Jacobian inverse for mobile manipulators

    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.

    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.

    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 micromillimeters 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 group 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.

    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.

    2010-11-01

    Recently we developed an opto-electrokinetic method for manipulating particles and cells called Rapid Electrokinetic Patterning (REP). REP is a very fast method for manipulating thousands of particles simultaneously and controllably owing to the creation of an electrothermal vortex that transports particles rapidly and in parallel to a site determined by the focal point of a laser beam. Whether particles are trapped at the center of the vortex or not is determined by their electrical properties (conductivity and permittivity). In this talk we demonstrate that REP can be used to manipulate the bacterium Shewanella oneidensis MR-1. The bacteria are assembled into large planar arrays of organisms. The dependence of this assembly process on voltage and frequency is quantified. REP can even be used to selectively manipulate and collect live or dead bacteria.

    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

  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

    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 definition of manipulability ellipsoids for dual robot systems is given. A suitable kineto-static formulation for dual cooperative robots is adopted which allows for a global task space description of external and internal forces, and relative velocities. 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.

    Surgical treatment options for patients with colonic inertia are costly and do not always relieve the pain associated with the condition. The author describes a case of a 41-year-old woman with colonic inertia who received osteopathic manipulative treatment targeted at the neuromusculoskeletal and gastrointestinal systems. The patient reported temporary improvement in pain and bowel function without pharmacotherapy or surgical intervention. Osteopathic manipulative treatment should be considered in patients with visceral as well as neuromusculoskeletal symptoms.

  11. 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

    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.

  13. Optimal and robust control of robot manipulators

    NASA Astrophysics Data System (ADS)

    Grabbe, Michael Thomas

    1992-01-01

    The problem of controlling a robot manipulator typically requires determining the actuating torques at each joint, in the form of a feedback control law, which force the manipulator joint angles to follow a prescribed trajectory. This problem is often referred to as the trajectory tracking problem, and is difficult to solve due to the highly nonlinear dynamics associated with the robot manipulator and the time variance of the system induced by the prescribed trajectory. The complexity of the problem is compounded in cases where the manipulator end effector is constrained by contact with a surface, there are modeling or parametric uncertainties in the manipulator dynamics, or there are disturbances to the system. The trajectory tracking problem is addressed in two distinct cases. The first case involves the ideal situation in which the manipulator is unconstrained in its motion and there are no uncertainties or disturbances in the system. Optimal control theory is used to develop a class of feedback control laws which produce a globally uniformly asymptotically stable (GUAS) system. The second case involves both constrained motion and the possibilities of uncertainties and disturbances in the system. Two feedback control laws are developed which are robust with respect to uncertainties and disturbances, provide globally exponentially stable (GES) position tracking error, and provide a means of regulating the force applied.

    2009-01-01

    Purpose: The theory of reasoned action is a health behavioral theory that has been used to predict personal health behaviors and intentions as well as those of providers delivering health care. The purpose of this study was to determine interns' future practices regarding the use of health promotion using this model to develop survey questions and to determine attitudes and perceived influences on their prospective behaviors in general, toward the use of health promotion once in practice. Methods: Across the course of one year, all graduating interns at a chiropractic college were queried with a 20 question survey designed using the theory of reasoned action. Frequencies and inferential statistics were performed including prediction modeling using logistic regression. Results: A majority (>85%) of interns indicated they would use health promotion in practice. Differences were noted based on perceived skill levels, perception of educational emphasis, various normative beliefs, and gender. Conclusion: Most interns will use some form of health promotion in practice. Normative influences including those seen as key influencers are as powerful a predictor as perceived education or skill levels on future practice of health promotion. PMID:19390679

    ABSTRACT Purpose: This practice survey describes how Fellows of the Canadian Academy of Manipulative Physiotherapy (FCAMPT) use spinal manipulation and mobilization and how they perceive their competence in performing spinal assessment; it also quantifies relationships between clinical experience and use of spinal manipulation. Methods: A cross-sectional survey was designed based on input from experts and the literature was administered to a random sample of the FCAMPT mailing list. Descriptive (including frequencies) and inferential statistical analyses (including linear regression) were performed. Results: The response rate was 82% (278/338 eligible FCAMPTs). Most (99%) used spinal manipulation. Two-thirds (62%) used clinical presentation as a factor when deciding to mobilize or manipulate. The least frequently manipulated spinal region was the cervical spine (2% of patients); 60% felt that cervical manipulation generated more adverse events. Increased experience was associated with increased use of upper cervical manipulation among male respondents (14% more often for every 10 years after certification; β, 95% CI=1.37, 0.89–1.85, p<0.001) but not among female respondents. Confidence in palpation accuracy decreased in lower regions of the spine. Conclusion: The use of spinal manipulation/mobilization is prevalent among FCAMPTs, but is less commonly used in the neck because of a perceived association with adverse events. PMID:24403681

    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

    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.

    The creation of dynamic manipulation behaviors for high degree of freedom, mobile robots will allow them to accomplish increasingly difficult tasks in the field. We are investigating how the coordinated use of the body, legs, and integrated manipulator, on a mobile robot, can improve the strength, velocity, and workspace when handling heavy objects. We envision that such a capability would aid in a search and rescue scenario when clearing obstacles from a path or searching a rubble pile quickly. Manipulating heavy objects is especially challenging because the dynamic forces are high and a legged system must coordinate all its degrees of freedom to accomplish tasks while maintaining balance. To accomplish these types of manipulation tasks, we use trajectory optimization techniques to generate feasible open-loop behaviors for our 28 dof quadruped robot (BigDog) by planning trajectories in a 13 dimensional space. We apply the Covariance Matrix Adaptation (CMA) algorithm to solve for trajectories that optimize task performance while also obeying important constraints such as torque and velocity limits, kinematic limits, and center of pressure location. These open-loop behaviors are then used to generate desired feed-forward body forces and foot step locations, which enable tracking on the robot. Some hardware results for cinderblock throwing are demonstrated on the BigDog quadruped platform augmented with a human-arm-like manipulator. The results are analogous to how a human athlete maximizes distance in the discus event by performing a precise sequence of choreographed steps.

  20. Blade manipulators in turbulent channel flow

    We report here the results of a series of careful experiments in turbulent channel flow, using various configurations of blade manipulators suggested as optimal in earlier boundary layer studies. The mass flow in the channel could be held constant to better than 0.1%, and the uncertainties in pressure loss measurements were less than 0.1 mm of water; it was therefore possible to make accurate estimates of the global effects of blade manipulation of a kind that are difficult in boundary layer flows. The flow was fully developed at the station where the blades were mounted, and always relaxed to the same state sufficiently far downstream. It is found that, for a given mass flow, the pressure drop to any station downstream is always higher in the manipulated than in the unmanipulated flow, demonstrating that none of the blade manipulators tried reduces net duct losses. However the net increase in duct losses is less than the drag of the blade even in laminar flow, showing that there is a net reduction in the total skin friction drag experienced by the duct, but this relief is only about 20% of the manipulator drag at most.

    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. PMID:26298610

    A number of diseases are associated with alterations in the composition of the microbiota of various niches of the human body. Although, in most cases, it is unclear if these alterations are the cause or the consequence of disease, they provide a rationale for therapeutic or prophylactic manipulation of a dysbiotic microbiota. Approaches to manipulate the microbiome include administration of either live bacteria, which are underrepresented in the diseased individual, substances that aim at increasing the populations of these bacteria, or a combination of the two. This chapter summarizes the available data in therapeutic manipulation of a various diseased states including irritable bowel syndrome, inflammatory bowel disease, necrotizing enterocolitis, atopic and allergic diseases, and antibiotic-associated and infectious diarrhoea.

    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.

    Attenuating start-up and stopping vibrations when maneuvering large payloads attached to flexible manipulator systems is a great concern for many space missions. To address this concern, it was proposed that the use of smart materials, and their applications in smart structures, may provide an effective method of control for aerospace structures. In this paper, a modified finite element model has been developed to simulate the performance of piezoelectric ceramic actuators, and was applied to a flexible two-arm manipulator system. Connected to a control voltage, the piezoelectric actuators produce control moments based on the optimal control theory. The computer simulation modeled the end-effector vibration suppression of the NASA manipulator testbed for berthing operations of the Space Shuttle to the Space Station. The results of the simulation show that the bonded piezoelectric actuators can effectively suppress follow-up vibrations of the end-effector, stimulated by some external disturbance.

    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.

    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.

    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.

  11. Planning Robotic Manipulation Strategies for Sliding Objects

    NASA Astrophysics Data System (ADS)

    Peshkin, Michael A.

    Automated planning of grasping or manipulation requires an understanding of both the physics and the geometry of manipulation, and a representation of that knowledge which facilitates the search for successful strategies. We consider manipulation on a level conveyor belt or tabletop, on which a part may slide when touched by a robot. Manipulation plans for a given part must succeed in the face of two types of uncertainty: that of the details of surfaces in contact, and that of the initial configuration of the part. In general the points of contact between the part and the surface it slides on will be unknown, so the motion of the part in response to a push cannot be predicted exactly. Using a simple variational principle (which is derived), we find the set of possible motions of a part for a given push, for all collections of points of contact. The answer emerges as a locus of centers of rotation (CORs). Manipulation plans made using this locus will succeed despite unknown details of contact. Results of experimental tests of the COR loci are presented. Uncertainty in the initial configuration of a part is usually also present. To plan in the presence of uncertainty, configuration maps are defined, which map all configurations of a part before an elementary operation to all possible outcomes, thus encapsulating the physics and geometry of the operation. The configuration map for an operation sequence is a product of configuration maps of elementary operations. Using COR loci we compute configuration maps for elementary sliding operations. Appropriate search techniques are applied to find operation sequences which succeed in the presence of uncertainty in the initial configuration and unknown details of contact. Such operation sequences may be used as parts feeder designs or as manipulation or grasping strategies for robots. As an example we demonstrate the automated design of a class of passive parts feeders consisting of multiple sequential fences across a conveyor

    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

    Aquaculture is one of the fastest developing agricultural industries worldwide. One of the most important factors for sustainable aquaculture is the development of high performing culture strains. Genome manipulation offers a powerful method to achieve rapid and directional breeding in fish. We review the history of fish breeding methods based on classical genome manipulation, including polyploidy breeding and nuclear transfer. Then, we discuss the advances and applications of fish directional breeding based on transgenic technology and recently developed genome editing technologies. These methods offer increased efficiency, precision and predictability in genetic improvement over traditional methods.

    A control hierarchy for a robotic manipulator is described. The hierarchy includes perception and robot/environment interaction, the latter consisting of planning, path control, and terminal guidance loops. Environment-sensitive features include the provision of control governed by proximity, tactile, and visual sensors as well as the usual kinematic sensors. The manipulator is considered as part of an overall robot system. 'Adaptive control' in the present context refers to both the hierarchical nature of the control system and to its environment-responsive nature.

    We report a simple but straightforward approach to fabricate magnetic nanofiber segments for cell manipulation. Electrospinning was used to produce nanofibers from a magnetic nanoparticles containing polymethylglutarimide (PMGI) precursor solution. After sonication, the fabricated nanofibers were uniformly segmented. When dispersed in an aqueous solution, the orientation of the fiber segments could easily be controlled by an external magnetic field. NIH 3T3 cells were then cultured in a medium containing magnetic fibers, resulting in stable cell-nanofiber hybrids which can be conveniently manipulated with a magnet.

    Four tasks (docking, coupling, manipulation, and transportation), stressing work volume and element relationships, are outlined to test a video system for remote manipulation in space. A 4 degree of freedom motion frame was used to evaluate operating parameters, which grouped the visual dimensions into major areas of influence, e.g., depth precision, object differentiation, reference, dynamics, and resolution. 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. The two-view system was found best suited for the operations described.

    A manipulator which provides fast, accurate rotational positioning of a small sphere, such as an inertial confinement fusion target, which allows inspecting of the entire surface of the sphere. The sphere is held between two flat, flexible tips which move equal amounts in opposite directions. This provides rolling of the ball about two orthogonal axes without any overall translation.

    Improved method of controlling mechanical impedance of end effector of redundant robotic manipulator based on adaptive-control theory. Consists of two subsystems: adaptive impedance controller generating force-control inputs in Cartesian space of end effector to provide desired end-effector-impedance characteristics, and subsystem implementing algorithm that maps force-control inputs into torques applied to joints of manipulator. Accurate control of end effector and effective utilization of redundancy achieved simultaneously by use of method. Potential use to improve performance of such typical impedance-control tasks as deburring edges and accommodating transitions between unconstrained and constrained motions of end effectors.

    Objective: We developed an adjusting bench with a force plate supporting the lumbar portion to measure loads transmitted during lumbar manual adjustment. It will be used to provide force-feedback to enhance student learning in technique labs. The study goal is to define the learning target loads and speeds, with instructors as expert models. Methods: A total of 11 faculty members experienced in teaching Gonstead technique methods performed 81 simulated adjustments on a mannequin on the force plate. Adjustments were along 9 lumbopelvic “listings” at 3 load levels: light, normal, and heavy. We analyzed the thrusts to find preload, peak load, duration, and thrust rate. Results: Analysis of 891 thrusts showed wide variations between doctors. Peak loads ranged from 100 to 1400 N. All doctors showed clear distinctions between peak load levels, but there was overlap between high and low loads. Thrust rates were more uniform across doctors, averaging 3 N/ms. Conclusion: These faculty members delivered a range of thrusts, not unlike those seen in the literature for high velocity, low amplitude manipulation. We have established at least minimum force and speed targets for student performance, but more work must be done to create a normative adjustment to guide refinement of student learning.

  2. Intelligent Behaviour Modelling and Control for Mobile Manipulators

    Elkady, Ayssam; Mohammed, Mohammed; Gebriel, Eslam; Sobh, Tarek

    In the last several years, mobile manipulators have been increasingly utilized and developed from a theoretical viewpoint as well as for practical applications in space, underwater, construction and service environments. The work presented in this chapter deals with the problem of intelligent behaviour modelling and control of a mobile manipulator for the purpose of simultaneously following desired end-effector and platform trajectories. Our mobile manipulator comprised a manipulator arm mounted on a motorized mobile base wheelchair. The need for accurate modelling of the mobile manipulator is crucial in designing and controlling the motion of the robot to achieve the target precision and manipulability requirements. In this chapter, we propose a new method for measuring the manipulability index used for serial manipulators. Furthermore, we provide some simulations that are implemented on different serial manipulators, such as the Puma 560 manipulator, a six degrees of freedom (DOF) manipulator and the Mitsubishi Movemaster manipulator. We then extend the manipulability concept commonly used for serial manipulators to general mobile manipulator systems.

    2010-01-01

    Purpose: To compare the effect of two learning opportunities, clinician feedback and video self-assessment, on 5th-year chiropractic students' patient communication skills, specifically those required for history taking. Methods: A cohort of 51 final-year students was divided into two groups. The first group received immediate feedback from a clinical supervisor following a history-taking encounter with a patient. The second group performed self-assessments of their videotaped history-taking encounter. An end-of-year Viva Voce examination was used to measure the effectiveness of the students' history-taking skills, using two subscores, one for behavior and another for content, as well as an overall total score. An unpaired t-test was performed to determine whether any significant difference occurred between the two groups of students. Each group was then subdivided into two subgroups based on gender, and a two-way analysis of variance was performed to determine whether the type of feedback or the students' gender had any significant effect on the outcome of the Viva Voce. Results: There were no significant differences between the two groups of students in terms of their final scores in the Viva Voce. After dividing each group into their gender subgroups and further analysis of the results, neither the mode of feedback nor the students' gender had any significant effect on the outcome of the Viva Voce. Conclusion: This study suggests that, for a mixed cohort, video self-assessment and clinician feedback are equivalent in their ability to enhance students' communication skills relating to history taking.

    1999-01-01

    The authors are interested in using low-degree-of-freedom robots to perform complex tasks by nonprehensile manipulation (manipulation without a form- or force-closure grasp). By not grasping, the robot can use gravitational, centrifugal, and Coriolis forces as virtual motors to control more degrees of freedom of the part. The part`s extra motion freedoms are exhibited as rolling, slipping, and free flight. This paper describes controllability, motion planning, and implementation of planar dynamic nonprehensile manipulation. The authors show that almost any planar object is controllable by point contact, and the controlling robot requires only two degrees of freedom (a point translating in the plane). They then focus on a one-joint manipulator (with a two-dimensional state space), and show that even this simplest of robots, by using slipping and rolling, can control a planar object to a full-dimensional subset of its six-0dimensional state space. The authors have developed a one-joint robot to perform a variety of dynamic tasks, including snatching an object from a table, rolling an object on the surface of the arm, and throwing and catching. Nonlinear optimization is used to plan robot trajectories that achieve the desired object motion via coupling forces through the nonprehensile contact.

    Modeling and control design for flexible manipulators, both from an experimental and analytical viewpoint, are described. From the application perspective, an ongoing effort within the laboratory environment at the Ohio State University, where experimentation on a single link flexible arm is underway is described. Several unique features of this study are described here. First, the manipulator arm is slewed by a direct drive dc motor and has a rigid counterbalance appendage. Current experimentation is from two viewpoints: (1) rigid body slewing and vibration control via actuation with the hub motor, and (2) vibration suppression through the use of structure-mounted proof-mass actuation at the tip. Such an application to manipulator control is of interest particularly in design of space-based telerobotic control systems, but has received little attention to date. From an analytical viewpoint, parameter estimation techniques within the closed-loop for self-tuning adaptive control approaches are discussed. Also introduced is a control approach based on output feedback and frequency weighting to counteract effects of spillover in reduced-order model design. A model of the flexible manipulator based on experimental measurements is evaluated for such estimation and control approaches.

    1984-07-01

    The problem of automatic camera tracking of mobile objects is addressed with specific reference to remote manipulators and using either fixed or mobile cameras. The technique uses a kinematic approach employing 4 x 4 coordinate transformation matrices to solve for the needed camera PAN and TILT angles. No vision feedback systems are used, as the required input data are obtained entirely from position sensors from the manipulator and the camera-positioning system. All hardware requirements are generally satisfied by currently available remote manipulator systems with a supervisory computer. The system discussed here implements linear plus on/off (bang-bang) closed-loop control with a +-2-deg deadband. The deadband area is desirable to avoid operator seasickness caused by continuous camera movement. Programming considerations for camera control, including operator interface options, are discussed. The example problem presented is based on an actual implementation using a PDP 11/34 computer, a TeleOperator Systems SM-229 manipulator, and an Oak Ridge National Laboratory (ORNL) camera-positioning system. 3 references, 6 figures, 2 tables.

    2012-06-01

    The creation of high degree of freedom dynamic mobile manipulation techniques and behaviors will allow robots to accomplish difficult tasks in the field. We are investigating the use of the body and legs of legged robots to improve the strength, velocity, and workspace of an integrated manipulator to accomplish dynamic manipulation. This is an especially challenging task, as all of the degrees of freedom are active at all times, the dynamic forces generated are high, and the legged system must maintain robust balance throughout the duration of the tasks. To accomplish this goal, we are utilizing trajectory optimization techniques to generate feasible open-loop behaviors for our 28 dof quadruped robot (BigDog) by planning the trajectories in a 13 dimensional space. Covariance Matrix Adaptation techniques are utilized to optimize for several criteria such as payload capability and task completion speed while also obeying constraints such as torque and velocity limits, kinematic limits, and center of pressure location. These open-loop behaviors are then used to generate feed-forward terms, which are subsequently used online to improve tracking and maintain low controller gains. Some initial results on one of our existing balancing quadruped robots with an additional human-arm-like manipulator are demonstrated on robot hardware, including dynamic lifting and throwing of heavy objects 16.5kg cinder blocks, using motions that resemble a human athlete more than typical robotic motions. Increased payload capacity is accomplished through coordinated body motion.

  3. The evolution of teleoperated manipulators at ORNL

    1996-12-31

    ORNL has made significant contributions to teleoperator and telerobotics technology for two decades and continues with an aggressive program today. Examples of past projects are: (1) the M2 servomanipulator, which was the first digitally controlled teleoperator; (2) the Advanced Servomanipulator (ASM), which was the first remotely maintainable teleoperator; (3) the CESARm/Kraft dissimilar teleoperated system; and (4) the Laboratory Telerobotic Manipulator (LTM), a 7-Degree-of-Freedom (7-DOF) telerobot built as a prototype for work in space. More recently, ORNL has become heavily involved with Environmental Restoration and Waste Management (ERWM) robotics programs funded by the Department of Energy (DOE). The ERWM program requires high payloads and high dexterity. As a result, a hydraulically actuated, dual-arm system comprised of two 6-DOF arms mounted on a 5-DOF base has been constructed and is being used today for various research tasks and for decontamination and dismantlement activities. All of these teleoperated manipulator systems build upon the experiences gained throughout the almost two decades of development. Each system incorporates not only the latest technology in computers, sensors, and electronics, but each new . system also adds at least one new feature to the technologies already developed and demonstrated in the previous system(s). As a result of this process, a serious study of these manipulator systems is a study in the evolution of teleoperated manipulator the systems in general. This provides insight not only into the research and development paths chosen in the past, but also into the appropriate directions for future teleoperator and telerobotics research. This paper examines each of the teleoperated/telerobotic systems developed at ORNL, summarizes their features and capabilities, examines the state of the most current telerobotic system (the Dual Arm Work Module), PM provides direction for a Next Generation Telerobotic Manipulator system.

  4. Ultrafast optical manipulation of magnetic order

    2010-07-01

    The interaction of subpicosecond laser pulses with magnetically ordered materials has developed into a fascinating research topic in modern magnetism. From the discovery of subpicosecond demagnetization over a decade ago to the recent demonstration of magnetization reversal by a single 40fs laser pulse, the manipulation of magnetic order by ultrashort laser pulses has become a fundamentally challenging topic with a potentially high impact for future spintronics, data storage and manipulation, and quantum computation. Understanding the underlying mechanisms implies understanding the interaction of photons with charges, spins, and lattice, and the angular momentum transfer between them. This paper will review the progress in this field of laser manipulation of magnetic order in a systematic way. Starting with a historical introduction, the interaction of light with magnetically ordered matter is discussed. By investigating metals, semiconductors, and dielectrics, the roles of (nearly) free electrons, charge redistributions, and spin-orbit and spin-lattice interactions can partly be separated, and effects due to heating can be distinguished from those that are not. It will be shown that there is a fundamental distinction between processes that involve the actual absorption of photons and those that do not. It turns out that for the latter, the polarization of light plays an essential role in the manipulation of the magnetic moments at the femtosecond time scale. Thus, circularly and linearly polarized pulses are shown to act as strong transient magnetic field pulses originating from the nonabsorptive inverse Faraday and inverse Cotton-Mouton effects, respectively. The recent progress in the understanding of magneto-optical effects on the femtosecond time scale together with the mentioned inverse, optomagnetic effects promises a bright future for this field of ultrafast optical manipulation of magnetic order or femtomagnetism.

  5. Manipulator Performance Evaluation Using Fitts' Taping Task

    1999-04-25

    Metaphorically, a teleoperator with master controllers projects the user's arms and hands into a re- mote area, Therefore, human users interact with teleoperators at a more fundamental level than they do with most human-machine systems. Instead of inputting decisions about how the system should func- tion, teleoperator users input the movements they might make if they were truly in the remote area and the remote machine must recreate their trajectories and impedance. This intense human-machine inter- action requires displays and controls more carefully attuned to human motor capabilities than is neces- sary with most systems. It is important for teleoperated manipulators to be able to recreate human trajectories and impedance in real time. One method for assessing manipulator performance is to observe how well a system be- haves while a human user completes human dexterity tasks with it. Fitts' tapping task has been, used many times in the past for this purpose. This report describes such a performance assessment. The International Submarine Engineering (ISE) Autonomous/Teleoperated Operations Manipulator (ATOM) servomanipulator system was evalu- ated using a generic positioning accuracy task. The task is a simple one but has the merits of (1) pro- ducing a performance function estimate rather than a point estimate and (2) being widely used in the past for human and servomanipulator dexterity tests. Results of testing using this task may, therefore, allow comparison with other manipulators, and is generically representative of a broad class of tasks. Results of the testing indicate that the ATOM manipulator is capable of performing the task. Force reflection had a negative impact on task efficiency in these data. This was most likely caused by the high resistance to movement the master controller exhibited with the force reflection engaged. Measurements of exerted forces were not made, so it is not possible to say whether the force reflection helped partici- pants

    The manipulator systems tested included the Meidensha BILARM 83A, the Central Research Laboratories Model M-2, and the GCA PaR Systems Model 6000. Six manipulator and control mode combinations were evaluated: (1) the BILARM in master/slave mode without force reflection, (2) the BILARM in master/slave mode with force reflection, (3) the Model M-2 in master/slave mode without force reflection, (4) the Model M-2 in master/slave mode with force reflection, (5) the BILARM with switchbox controls, and (6) the PaR 6000 with switchbox controls. The experiments examined differences between master/slave systems with and without force reflection and differences between master/slave systems and switchbox-controlled systems. A fourth experiment examined the relative contributions of the remote viewing system and the manipulator system to the performance of remote handling tasks. Results of the experiments showed that operators using the Model M-2 in master/slave mode had significantly faster times to completion than operators using the BILARM in master/slave mode, with about the same error rate per trial. Operators were slower using the BILARM with force reflection than without it, and they committed more errors. There was no statistically significant difference between force-reflection and nonforce-reflection conditions for the M-2 manipulator for any of the performance criteria. Tasks and procedures used in this testing were not sensitive to differences within any single system. No inferences about the effect of force reflection on remote task performance should be made from these data. The two manipulator systems in switchbox mode had significantly slower times to completion than any system in master/slave mode, with approximately the same error rate per trial. There were no significant differences between the BILARM in switchbox mode and the PaR arm.

  7. Graphene plasmonic lens for manipulating energy flow

    2014-02-01

    Manipulating the energy flow of light is at the heart of modern information and communication technologies. Because photons are uncharged, it is still difficult to effectively control them by electrical means. Here, we propose a graphene plasmonic (GP) lens to efficiently manipulate energy flow by elaborately designing the thickness of the dielectric spacer beneath the graphene sheet. Different from traditional metal-based lenses, the proposed graphene plasmonic lens possesses the advantages of tunability and excellent confinement of surface plasmons. It is found that the proposed lens can be utilized to focus and collimate the GP waves propagating along the graphene sheet. Particularly, the lens is dispersionless over a wide frequency range and the performance of lens can be flexibly tuned by adjusting the bias voltage. As an application of such a lens, the image transfer of two point sources with a separation of λ0/30 is demonstrated.

    In the United States, candidemia is one of the most common hospital-acquired infections and is estimated to cause 10,000 deaths per year. The species Candida albicans is responsible for the majority of these cases. As C. albicans is capable of developing resistance against the currently available drugs, understanding the molecular basis of drug resistance, finding new cellular targets, and further understanding the overall mechanism of C. albicans pathogenesis are important goals. To study this pathogen it is advantageous to manipulate its genome. Numerous strategies of C. albicans gene manipulation have been introduced. This review evaluates a majority of these strategies and should be a helpful guide for researchers to identify gene targeting strategies to suit their requirements. PMID:21511047

    The use of dental implants for the rehabilitation of missing teeth has broadened the treatment options for patients and clinicians equally. As a result of advances in research in implant design, materials, and techniques, the use of dental implants has increased dramatically in the past two decades and is expected to expand further in the future. Success of dental implants depends largely on the quality and quantity of the available bone in the recipient site. This however may be compromised or unavailable due to tumor, trauma, periodontal disease, etc., which in turn necessitates the need for additional bone manipulation. This review outlines the various bone manipulation techniques that are used to achieve a predictable long-term success of dental implants. PMID:27433052

    The Bergman cyclization is one of the most fascinating rearrangements in chemistry, with important implications in organic synthesis and pharmacology. Here we demonstrate a reversible Bergman cyclization for the first time. We induced the on-surface transformation of an individual aromatic diradical into a highly strained ten-membered diyne using atomic manipulation and verified the products by non-contact atomic force microscopy with atomic resolution. The diyne and diradical were stabilized by using an ultrathin NaCl film as the substrate, and the diyne could be transformed back into the diradical. Importantly, the diradical and the diyne exhibit different reactivity, electronic, magnetic and optical properties associated with the changes in the bond topology, and spin multiplicity. With this reversible, triggered Bergman cyclization we demonstrated switching on demand between the two reactive intermediates by means of selective C-C bond formation or cleavage, which opens up the field of radical chemistry for on-surface reactions by atomic manipulation.

    Typically, metal particles are difficult to manipulate with conventional optical vortex (OV) tweezers, because of their strong absorption and scattering. However, it has been shown that the vortex field of surface plasmonic polaritons, called plasmonic vortex (PV), is capable of stable trapping and dynamic rotation of metal particles, especially those of mesoscopic and Mie size. To uncover the different physical mechanisms of OV and PV tweezers, we investigated the force distribution and trapping potential of metal particles. In OV tweezers the stronger scattering force causes a positive potential barrier that repels particles, whereas in PV tweezers the dominant gradient force contributes to a negative potential well, resulting in stably trapped particles. Compared with OV, the orbital angular momentum of PV produces an azimuthal scattering force that rotates the trapped particles with more precise radius and position. Our results demonstrate that PV tweezers are superior in manipulation of metal particles. PMID:26481689

  13. Acoustic Resonator Optimisation for Airborne Particle Manipulation

    Devendran, Citsabehsan; Billson, Duncan R.; Hutchins, David A.; Alan, Tuncay; Neild, Adrian

    Advances in micro-electromechanical systems (MEMS) technology and biomedical research necessitate micro-machined manipulators to capture, handle and position delicate micron-sized particles. To this end, a parallel plate acoustic resonator system has been investigated for the purposes of manipulation and entrapment of micron sized particles in air. Numerical and finite element modelling was performed to optimise the design of the layered acoustic resonator. To obtain an optimised resonator design, careful considerations of the effect of thickness and material properties are required. Furthermore, the effect of acoustic attenuation which is dependent on frequency is also considered within this study, leading to an optimum operational frequency range. Finally, experimental results demonstrated good particle levitation and capture of various particle properties and sizes ranging to as small as 14.8 μm.

    2014-01-01

    We explore a transformational approach to the problem of verifying simple array-manipulating programs. Traditionally, verification of such programs requires intricate analysis machinery to reason with universally quantified statements about symbolic array segments, such as "every data item stored in the segment A[i] to A[j] is equal to the corresponding item stored in the segment B[i] to B[j]." We define a simple abstract machine which allows for set-valued variables and we show how to translate programs with array operations to array-free code for this machine. For the purpose of program analysis, the translated program remains faithful to the semantics of array manipulation. Based on our implementation in LLVM, we evaluate the approach with respect to its ability to extract useful invariants and the cost in terms of code size.

QX MAN combines many of the features frequently encountered in grid generation, grid refinement, the setting-up of initial conditions, and post processing. QX MAN allows the user to manipulate single block and multi-block grids (and their accompanying solution files) by splitting, concatenating, rotating, translating, re-scaling, and stripping or adding points. In addition, QX MAN can be used to generate an initial solution file for the PARC code. The code was written to provide several formats for input and output in order for it to be useful in a broad spectrum of applications.

We used a Bluetooth module to send the commands to control the moving of the manipulator. The system is formed by three parts: the first part, the program made in Android. It is run on the Smartphone that controls the position of the robot. The second part is the reception board based in the PIC18F4550 that energizes the joints of the manipulator. The last part is the driver. It use an integrated circuit L293D that is configured in two full bridges H. This system is a good tool for learning of programing, sensors, actuators, robotic, electronic and design electronic.

    To manipulate large payloads typical of space construction, the concept of a small arm mounted on the end of a large arm is introduced. The main purposes of such a configuration are to increase the structural stiffness of the robot by bracing against or locking to a stationary frame, and to maintain a firm position constraint between the robot's base and workpieces by grasping them. Possible topologies for a combination of disparate large and small arms are discussed, and kinematics, dynamics, controls, and coordination of the two arms, especially when they brace at the tip of the small arm, are developed. The feasibility and improvement in performance are verified, not only with analytical work and simulation results but also with experiments on the existing arrangement Robotic Arm Large and Flexible and Small Articulated Manipulator.

    A payload lifter/manipulator module includes a rotatable joint supporting spreader arms angularly spaced with respect to one another. A rigid arm is fixedly coupled to the joint and extends out therefrom to a tip. A tension arm has a first end and a second end with the first end being fixedly coupled to the tip of the rigid arm. The tension arm incorporates pivots along the length thereof. Each pivot can be engaged by or disengaged from the outboard end of a spreader arm based on a position of the spreader arm. A hoist, positioned remotely with respect to the module and coupled to the second end of the tension arm, controls the position of the spreader arms to thereby control the position of the rigid arm's tip. Payload lifter/manipulator assemblies can be constructed with one or more of the modules.

  19. Extended SQL for manipulating clinical warehouse data.

    Johnson, S B; Chatziantoniou, D

    1999-01-01

    Health care institutions are beginning to collect large amounts of clinical data through patient care applications. Clinical data warehouses make these data available for complex analysis across patient records, benefiting administrative reporting, patient care and clinical research. Data gathered for patient care purposes are difficult to manipulate for analytic tasks; the schema presents conceptual difficulties for the analyst, and many queries perform poorly. An extension to SQL is presented that enables the analyst to designate groups of rows. These groups can then be manipulated and aggregated in various ways to solve a number of useful analytic problems. The extended SQL is concise and runs in linear time, while standard SQL requires multiple statements with polynomial performance. The extensions are extremely powerful for performing aggregations on large amounts of data, which is useful in clinical data mining applications.

    Dacryostenosis is an obstruction of the nasolacrimal duct and is the most common cause of epiphora and ocular discharge in newborns. Whereas most cases resolve spontaneously, invasive treatment may become necessary if symptoms persist past age 6 to 12 months. In the present case, a 9-month-old boy with persistent dacryostenosis was scheduled for lacrimal duct probing after first-line treatments failed. After a single session of osteopathic manipulative treatment, the patient's epiphora and other symptoms resolved, and he no longer needed surgical probing. A review of the literature highlights key pathophysiologic processes, management options, and musculoskeletal aspects of dacryostenosis. Physicians should consider osteopathic manipulative treatment in the management of dacryostenosis.

    1994-01-01

    The work reported deals with the problem of operating a robot manipulator under a rate control mode while the end effector is not in contact with the external environment, and then switching to a force control mode when contact is made. The paper details how the modal changeover may be accomplished in a manner transparent to the operator, and will allow operator applied forces to be reflected at the robot end effector. A one degree of freedom demonstration system is used to illustrate the concept, which is then applied to a PUMA manipulator. Sample code for the implementation of the control is provided, experimental results show that the optimum setting for the gain is a function of the compliance of the end effector, and the compliance of the external constraint.

    This paper describes an acalculic patient (B.A.L.) with an unusual selective deficit in manipulating arabic numerals. The patient was unimpaired in reading aloud letters, words and written number names but unable to read aloud single arabic numerals. Furthermore, his ability to produce the next number in the sequence and his ability to produce answers to simple addition and subtraction was relatively spared when the stimuli were presented as number names but impaired when the stimuli were presented as arabic numerals. Using magnitude comparison tasks it was demonstrated that his knowledge of cardinal values of arabic numerals was preserved.

    A certain number of considerations should be taken into account in the dynamic control of robot manipulators as highly complex non-linear systems. In this article, we provide a detailed presentation of the mechanical and electrical implications of robots equipped with DC motor actuators. This model takes into account all non-linear aspects of the system. Then, we develop computational algorithms for optimal control based on dynamic programming. The robot's trajectory must be predefined, but performance criteria and constraints applying to the system are not limited and we may adapt them freely to the robot and the task being studied. As an example, a manipulator arm with 3 degress of freedom is analyzed.

    We previously demonstrated that disrupting reconsolidation by pharmacological manipulations "deleted" the emotional expression of a fear memory in humans. If we are to target reconsolidation in patients with anxiety disorders, the disruption of reconsolidation should produce content-limited modifications. At the same time, the fear-erasing effects should not be restricted to the feared cue itself considering that fear generalization is a main characteristic of anxiety disorders. In Experiment I and Experiment I(b), we addressed these issues using a within-subject differential startle fear conditioning paradigm and a test of fear generalization. In Experiment II, we tested whether a behavioral approach targeting the reconsolidation through extinction learning was also effective in weakening the original fear memory. A behavioral procedure is evidently preferred over drug manipulations provided that similar effects can be obtained. Here, the extinction procedure subsequent to retrieval did not "erase" the emotional expression of the fear memory as the retrieval techniques (i.e., reminder shocks and reacquisition) unveiled a return of the startle fear response to the fear-relevant stimuli. In contrast, β-adrenergic receptor blockade during reconsolidation selectively deleted the fear-arousing aspects of the memory (i.e., startle fear response) along with its category-related information. The pharmacological manipulation rendered the core memory trace too weak to observe fear generalization after successful reacquisition. Hence, relearning following the disruption of reconsolidation seems to be qualitatively different from initial learning. Our findings demonstrate that disrupting reconsolidation by pharmacological manipulations, although selective, undermines the generalization of fear, a key feature of anxiety disorders.

    The effect of the Magnus force in optical micromanipulation has been observed. An ad hoc experiment has been designed based on a one-dimensional optical trap that carries angular momentum. The observed particle dynamics reveals the occurrence of this hydrodynamic force, which is neglected in the common approach. Its measured value is larger than the one predicted by the existing theoretical models for micrometric particles and low Reynolds number, showing that the Magnus force can contribute to unconventional optohydrodynamic trapping and manipulation.

    The Space Station Remote Manipulator System (SSRMS), Canadarm2, was launched in 2001 and deployed on the International Space Station (ISS). The Canadarm2 has been instrumental in ISS assembly and maintenance. Canadarm2 shares its heritage with the Space Shuttle Arm (Canadarm). This article explores the evolution from the Shuttle Canadarm to the Space Station Canadarm2 design, which incorporates a 7 degree of freedom design, larger joints, and changeable operating base. This article also addresses phased design, redundancy, life and maintainability requirements. The design of Canadarm2 meets unique ISS requirements, including expanded handling capability and the ability to be maintained on orbit. The size of ISS necessitated a mobile manipulator, resulting in the unique capability of Canadarm2 to relocate by performing a walk off to base points located along the Station, and interchanging the tip and base of the manipulator. This provides the manipulator with reach and access to a large part of the Station, enabling on-orbit assembly of the Station and providing support to Extra-Vehicular Activity (EVA). Canadarm2 is evolving based on on-orbit operational experience and new functionality requirements. SSRMS functionality is being developed in phases to support evolving ISS assembly and operation as modules are added and the Station becomes more complex. Changes to sustaining software, hardware architecture, and operations have significantly enhanced SSRMS capability to support ISS mission requirements. As a result of operational experience, SSRMS changes have been implemented for Degraded Joint Operations, Force Moment Sensor Thermal Protection, Enabling Ground Controlled Operations, and Software Commutation. Planned Canadarm2 design modifications include: Force Moment Accommodation, Smart Safing, Separate Safing, and Hot Backup. In summary, Canadarm2 continues to evolve in support of new ISS requirements and improved operations. It is a tribute to the design that

    Mycobacterium tuberculosis (MTB) is one of the most successful pathogens in human history and remains a global health challenge. MTB has evolved a plethora of strategies to evade the immune response sufficiently to survive within the macrophage in a bacterial-immunological equilibrium, yet causes sufficient immunopathology to facilitate its transmission. This review highlights MTB as the driver of disease pathogenesis and presents evidence of the mechanisms by which MTB manipulates the protective immune response into a pathological productive infection.

    We review our investigations of the use of static magnetic fields, B, for manipulating cells and cellular processes. We describe how B fields modify the cell division pattern of frog embryos and consequently can be used to probe the pattern determinants. We also observe that magnetic fields modify the swimming behavior of Paramecium Caudatum. We describe these modifications and their potential application to investigations of their swimming behavior.

    This paper discusses a new telerobotic control concept and its implementation using a PUMA-560 robot manipulator. The control concept couples human supervisory commands with computer reasoning. The control system is responsive and accomplishes an operator's commands while providing obstacle avoidance and controlled interactions with the environment where desired. This provides a system which not only assists the operator in accomplishing tasks but modifies inappropriate operator commands which can result in safety hazards and/or equipment damage. 15 refs., 6 figs.

    Blair, John [Kansas State University; Fay, Phillip [USDA-ARS; Knapp, Alan [Colorado State University; Collins, Scott [University of New Mexico; Smith, Melinda [Yale University

    Rainfall Manipulation Plots facility (RaMPs) is a unique experimental infrastructure that allows us to manipulate precipitation events and temperature, and assess population community, and ecosystem responses in native grassland. This facility allows us to manipulate the amount and timing of individual precipitation events in replicated field plots at the Konza Prairie Long-Term Ecological Research (LTER) site. Questions we are addressing include: • What is the relative importance of more extreme precipitation patterns (increased climatic variability) vs. increased temperatures (increased climatic mean) with regard to their impact on grassland ecosystem structure and function? Both projected climate change factors are predicted to decrease soil water availability, but the mechanisms by which this resource depletion occurs differ. • Will altered precipitation patterns, increased temperatures and their interaction increase opportunities for invasion by exotic species? • Will long-term (6-10 yr) trajectories of community and ecosystem change in response to more extreme precipitation patterns continue at the same rate as initial responses from years 1-6? Or will non-linear change occur as potential ecological thresholds are crossed? And will increased temperatures accelerate these responses? Data sets are available as ASCII files, in Excel spreadsheets, and in SAS format. (Taken from http://www.konza.ksu.edu/ramps/backgrnd.html

  18. Optogenetic Glia Manipulation: Possibilities and Future Prospects

    Cho, Woo-Hyun; Barcelon, Ellane

    2016-01-01

    Our brains are composed of two distinct cell types: neurons and glia. Emerging data from recent investigations show that glial cells, especially astrocytes and microglia, are able to regulate synaptic transmission and thus brain information processing. This suggests that, not only neuronal activity, but communication between neurons and glia also plays a key role in brain function. Thus, it is currently well known that the physiology and pathophysiology of brain function can only be completely understood by considering the interplay between neurons and glia. However, it has not yet been possible to dissect glial cell type-specific roles in higher brain functions in vivo. Meanwhile, the recent development of optogenetics techniques has allowed investigators to manipulate neural activity with unprecedented temporal and spatial precision. Recently, a series of studies suggested the possibility of applying this cutting-edge technique to manipulate glial cell activity. This review briefly discusses the feasibility of optogenetic glia manipulation, which may provide a technical innovation in elucidating the in vivo role of glial cells in complex higher brain functions.

    2016-02-01

    We report a manipulation of biological cells (erythrocytes) by magnetite (Fe3O4) nanoparticles in the presence of a magnetic field. The experiment was accomplished on the top of a micro-electromagnet consisting of two magnetic field generating contours. An electric current flowing through the contour(s) produces a non-uniform magnetic field, which is about 1.4 mT/μm in strength at 100 mA current in the vicinity of the current-carrying wire. In responses to the magnetic field, magnetic nanoparticles move towards the systems energy minima. In turn, magnetic nanoparticles drag biological cells in the same direction. We present experimental data showing cell manipulation through the control of electric current. This technique allows us to capture and move cells located in the vicinity (10-20 microns) of the current-carrying wires. One of the most interesting results shows a periodic motion of erythrocytes between the two conducting contours, whose frequency is controlled by an electric circuit. The obtained results demonstrate the feasibility of non-destructive cell manipulation by magnetic nanoparticles with micrometer-scale precision.

  20. Genetic Manipulation of Human Embryonic Stem Cells.

    Eiges, Rachel

    2016-01-01

    One of the great advantages of embryonic stem (ES) cells over other cell types is their accessibility to genetic manipulation. They can easily undergo genetic modifications while remaining pluripotent, and can be selectively propagated, allowing the clonal expansion of genetically altered cells in culture. Since the first isolation of ES cells in mice, many effective techniques have been developed for gene delivery and manipulation of ES cells. These include transfection, electroporation, and infection protocols, as well as different approaches for inserting, deleting, or changing the expression of genes. These methods proved to be extremely useful in mouse ES cells, for monitoring and directing differentiation, discovering unknown genes, and studying their function, and are now being extensively implemented in human ES cells (HESCs). This chapter describes the different approaches and methodologies that have been applied for the genetic manipulation of HESCs and their applications. Detailed protocols for generating clones of genetically modified HESCs by transfection, electroporation, and infection will be described, with special emphasis on the important technical details that are required for this purpose. All protocols are equally effective in human-induced pluripotent stem (iPS) cells.
