    Despite intensive neurorehabilitation, extensive functional recovery after spinal cord injury is unattainable for most individuals. Optimal recovery will likely depend on activity-based, task-specific training that personalizes the timing of intervention with the severity of injury. Exercise paradigms elicit both beneficial and deleterious biophysical effects after spinal cord injury. Modulating the type, intensity, complexity, and timing of training may minimize risk and induce greater recovery. This review discusses the following: (a) the biological underpinning of training paradigms that promote motor relearning and recovery, and (b) how exercise interacts with cellular cascades after spinal cord injury. Clinical implications are discussed throughout. PMID:21703584

  2. Exercise and spinal manipulation in the treatment of low back pain.

    Current research clearly indicates the importance of exercise and mobility in the treatment of low back pain and also that bed rest and inactivity should play a relatively small part in treatment. The use of intensive, physical exercise and "work hardening" routines have been shown to be necessary for treating chronic low back pain and returning individuals to work. Evidence derived from valid clinical studies of the use of manipulation in the treatment of low back pain shows a role for it in the acute treatment of "mechanical" low back disorders. These studies have demonstrated that manipulative procedures result in more rapid pain and functional relief compared with other conservative therapies. Over a longer time frame, this advantage disappears. PMID:7604333

    After spinal surgery, physiotherapeutic exercises are performed to achieve a rapid return to normal life. One important aim of treatment is to regain muscle strength, but it is known that muscle forces increase the spinal loads to potentially hazardous levels. It has not yet been clarified which exercises cause high spinal forces and thus endanger the surgical outcome. The loads on vertebral body replacements were measured in 5 patients during eleven physiotherapeutic exercises, performed in the supine, prone, or lateral position or on all fours (kneeling on the hands and knees). Low resultant forces on the vertebral body replacement were measured for the following exercises: lifting one straight leg in the supine position, abduction of the leg in the lateral position, outstretching one leg in the all-fours position, and hollowing the back in the all-fours position. From the biomechanical point of view, these exercises can be performed shortly after surgery. Implant forces similar or even greater than those for walking were measured during: lifting both legs, lifting the pelvis in the supine position, outstretching one arm with or without simultaneously outstretching the contralateral leg in the all-fours position, and arching the back in the all-fours position. These exercises should not be performed shortly after spine surgery. PMID:24999808

    Given that the spinal cord is capable of learning sensorimotor tasks and that dietary interventions can influence learning involving supraspinal centers, we asked whether the presence of omega-3 fatty acid docosahexaenoic acid (DHA) and the curry spice curcumin (Cur) by themselves or in combination with voluntary exercise could affect spinal cord learning in adult spinal mice. Using an instrumental learning paradigm to assess spinal learning we observed that mice fed a diet containing DHA/Cur performed better in the spinal learning paradigm than mice fed a diet deficient in DHA/Cur. The enhanced performance was accompanied by increases in the mRNA levels of molecular markers of learning, i.e., BDNF, CREB, CaMKII, and syntaxin 3. Concurrent exposure to exercise was complementary to the dietary treatment effects on spinal learning. The diet containing DHA/Cur resulted in higher levels of DHA and lower levels of omega-6 fatty acid arachidonic acid (AA) in the spinal cord than the diet deficient in DHA/Cur. The level of spinal learning was inversely related to the ratio of AA:DHA. These results emphasize the capacity of select dietary factors and exercise to foster spinal cord learning. Given the non-invasiveness and safety of the modulation of diet and exercise, these interventions should be considered in light of their potential to enhance relearning of sensorimotor tasks during rehabilitative training paradigms after a spinal cord injury.

    The H-reflex habituates at relatively low frequency (10 Hz) stimulation in the intact spinal cord, but loss of descending inhibition resulting from spinal cord transection reduces this habituation. There is a return towards a normal pattern of low-frequency habituation in the reflex activity with cycling exercise of the affected hind limbs. This implies that repetitive passive stretching of the muscles in spinalized animals and the accompanying stimulation of large (Group I and II) proprioceptive fibers has modulatory effects on spinal cord reflexes after injury. To test this hypothesis, we induced pyridoxine neurotoxicity that preferentially affects large dorsal root ganglia neurons in intact and spinalized rats. Pyridoxine or saline injections were given twice daily (IP) for 6 weeks and half of the spinalized animals were subjected to cycling exercise during that period. After 6 weeks, the tibial nerve was stimulated electrically and recordings of M and H waves were made from interosseous muscles of the hind paw. Results show that pyridoxine treatment completely eliminated the H-reflex in spinal intact animals. In contrast, transection paired with pyridoxine treatment resulted in a reduction of the frequency-dependent habituation of the H-reflex that was not affected by exercise. These results indicate that normal Group I and II afferent input is critical to achieve exercise-based reversal of hyper-reflexia of the H-reflex after spinal cord injury. PMID:19913536

  6. EMG Biofeedback and Exercise for Treatment of Cervical and Shoulder Pain in Individuals with a Spinal Cord Injury: A Pilot Study

    PubMed Central

    2013-01-01

    Background: Chronic or recurrent musculoskeletal pain in the cervical and shoulder region is a common secondary problem after spinal cord injury (SCI), reported by 30% to 70% of individuals. Objective: The purpose of this study was to investigate the effect of electromyographic (EMG) biofeedback training, in addition to a standard exercise program, on reducing shoulder pain in manual wheelchair users with SCI. Methods: Fifteen individuals with SCI, C6 or lower, who were manual wheelchair users with shoulder pain were randomly assigned to 1 of 2 interventions. The Exercise group (n = 7) received instruction on a standard home-based exercise program. The EMG Biofeedback plus Exercise group (n = 8) received identical exercise instruction plus EMG biofeedback training to improve muscle balance and muscle relaxation during wheelchair propulsion. Shoulder pain was assessed by the Wheelchair Users Shoulder Pain Index (WUSPI) at baseline, at posttest 10 weeks after the start of intervention, and at follow-up 16 weeks after posttest. Results: The number of participants per group allowed only within-group comparisons; however, the findings indicated a beneficial effect from EMG biofeedback training. Shoulder pain, as measured by WUSPI, decreased 64% from baseline to posttest for the EMG Biofeedback plus Exercise group (P = .02). Shoulder pain for the Exercise group decreased a nonsignificant 27%. At follow-up, both groups showed continued improvement, yet the benefit of EMG biofeedback training was still discernible. The EMG Biofeedback plus Exercise group had an 82% reduction in shoulder pain from baseline to follow-up (P = .004), while the Exercise group showed a 63% reduction (P = .03) over the same time period. Conclusions: This study provides preliminary evidence that EMG biofeedback has value when added to an exercise intervention to reduce shoulder pain in manual wheelchair users with SCI. These findings indicate that EMG biofeedback may be valuable in remediating

  7. Short term treatment versus long term management of neck and back disability in older adults utilizing spinal manipulative therapy and supervised exercise: a parallel-group randomized clinical trial evaluating relative effectiveness and harms

    PubMed Central

    2014-01-01

    Background Back and neck disability are frequent in older adults resulting in loss of function and independence. Exercise therapy and manual therapy, like spinal manipulative therapy (SMT), have evidence of short and intermediate term effectiveness for spinal disability in the general population and growing evidence in older adults. For older populations experiencing chronic spinal conditions, long term management may be more appropriate to maintain improvement and minimize the impact of future exacerbations. Research is limited comparing short courses of treatment to long term management of spinal disability. The primary aim is to compare the relative effectiveness of 12 weeks versus 36 weeks of SMT and supervised rehabilitative exercise (SRE) in older adults with back and neck disability. Methods/Design Randomized, mixed-methods, comparative effectiveness trial conducted at a university-affiliated research clinic in the Minneapolis/St. Paul, Minnesota metropolitan area. Participants Independently ambulatory community dwelling adults ≥ 65 years of age with back and neck disability of minimum 12 weeks duration (n = 200). Interventions 12 weeks SMT + SRE or 36 weeks SMT + SRE. Randomization Blocked 1:1 allocation; computer generated scheme, concealed in sequentially numbered, opaque, sealed envelopes. Blinding Functional outcome examiners are blinded to treatment allocation; physical nature of the treatments prevents blinding of participants and providers to treatment assignment. Primary endpoint 36 weeks post-randomization. Data collection Self-report questionnaires administered at 2 baseline visits and 4, 12, 24, 36, 52, and 78 weeks post-randomization. Primary outcomes include back and neck disability, measured by the Oswestry Disability Index and Neck Disability Index. Secondary outcomes include pain, general health status, improvement, self-efficacy, kinesiophobia, satisfaction, and medication use. Functional outcome assessment occurs

    Exercise is an essential element in managing several of the non-communicable diseases after spinal cord injury (SCI). Awareness of the importance of prescribing a customized exercise program that meets the goals of persons with SCI should be highly considered in the rehabilitation community. The barriers of implementing specific exercise program as well as the factors that may mask the outcomes of regular exercise regimen need to be continuously addressed as a part of patients' rehabilitation care. The focus of this editorial is to encourage the medical community to consider routine physical activity as one of the necessary vital signs that needs to be routinely checked in patients with SCI. Providing education tips, nutritional counseling and engaging in recreational programs may provide motivational route to the community of SCI. This may result in reinforcing active lifestyle in survivors with SCI as well as to reduce the impact of chronic life threatening medical disorders. PMID:25035817

    Locomotion recovery after a spinal cord injury (SCI) includes axon regeneration, myelin preservation and increased plasticity in propriospinal and descending spinal circuitries. The combined effects of tamoxifen and exercise after a SCI were analyzed in this study to determine whether the combination of both treatments induces the best outcome in locomotion recovery. In this study, the penetrating injury was provoked by a sharp projectile that penetrates through right dorsal and ventral portions of the T13-L1 spinal segments, affecting propriospinal and descending/ascending tracts. Intraperitoneal application of Tamoxifen and a treadmill exercise protocol, as rehabilitation therapies, separately or combined, were used. To evaluate the functional recovery, angular patterns of the hip, knee and ankle joints as well as the leg pendulum-like movement (PLM) were measured during the unrestricted gait of treated and untreated (UT) animals, previously and after the traumatic injury (15 and 30days post-injury (dpi)). A pattern (curve) comparison analysis was made by using a locally designed Matlab script that determines the Frechet dissimilarity. The SCI magnitude was assessed by qualitative and quantitative histological analysis of the injury site 30days after SCI. Our results showed that all treated groups had an improvement in hindlimbs kinematics compared to the UT group, which showed a poor gait locomotion recovery throughout the rehabilitation period. The group with the combined treatment (tamoxifen+exercise (TE)) presented the best outcome. In conclusion, tamoxifen and treadmill exercise treatments are complementary therapies for the functional recovery of gait locomotion in hemi-spinalized rats. PMID:27450566

    Background Context: Chronic low back pain (CLBP) is a prevalent disorder that has a significant burden to society in terms of loss of work time and increased economic cost. Two common treatment choices of intervention for CLBP are spinal manipulation and prescribed exercise. Purpose: The purpose of this systematic review was to examine the effectiveness of spinal manipulation vs prescribed exercise for patients diagnosed with CLBP. Studies that compared head-to-head spinal manipulation to an exercise group were included in this review. Methods: A search of the current literature was conducted using a keyword process in CINAHL, Cochrane Register of Controlled Trials Database, Medline, and Embase. The search was conducted on, and included studies available up to August 29th 2014. Studies were included based on PICOS criteria 1) individuals with CLBP defined as lasting 12 weeks or longer; 2) spinal manipulation performed by a health care practitioner; 3) prescribed exercise for the treatment of CLBP and monitored by a health care practitioner; 4) measurable clinical outcomes for reducing pain, disability or improving function; 5) randomized controlled trials. The quality of included articles was determined by the author using the criteria developed and used by the Physiotherapy Evidence Database (PEDro). Results: Three randomized controlled trials met the inclusion criteria of this systematic review and were included in this review. The outcomes used in these studies included Disability Indexes, Pain Scales and function improvement scales. The results included a mix of effects with one study finding spinal manipulation as more effective and another finding the exercises more so. The third study found both interventions offering equal effects in the long term. Conclusion: Based on the findings of this systematic review there is no conclusive evidence that clearly favours spinal manipulation or exercise as more effective in treatment of CLBP. More studies are needed to

    Neuropathy is a long-standing and hard to treat complication of diabetes that interferes almost 25-30% of diabetic patients and impacts the quality of life of the patients. Unforeseen side effects, dependency and addiction made the existing medical treatments comparatively ineffective. A number of studies indicate that moderate physical activity provides health-related advantages. However, existing data do not confirm whether regular physical activity would reduce the amount of inflammation in the nervous system of the subjects with Type 1 diabetes. This study reveals the significance of exercise to alleviate inflammation in the spinal cord of the nervous system and preserve sensory nerve function in animals with Type 1 diabetes after 6 weeks of exercise paradigm. Streptozotocin-diabetic animals were placed in motorized running wheels for sixty minutes per day, for five days a week for 6 weeks starting at one week after diabetes. Emerging evidence suggests that the increases in inflammatory mediators play an important role in the development of sensory neuropathy. This study shows that moderate exercise can reduce the release of a number of proinflammatory cytokines in the dorsal horn (DH) of spinal cord, subsequently delaying the development of neuropathy along with an increase in the anti-inflammatory mediator IL10 in the DH. In general, this study indicates that exercise may provide an alternative to the treatment for sensory neuropathy in Type 1 diabetic subjects via reducing the use of medication and providing an easier way to manage neuropathy.

    Context Due to advances in acute oncological treatment, patients with spinal cord tumors exhibit improved survival. However, these patients have not received the full benefits of rehabilitation services to address their neurological deficits and rehabilitation goals. Objective To evaluate the epidemiology and pathophysiology of spinal cord tumors, address methods of acute oncological management, review treatment for neurological sequelae, and understand the implications as they relate to rehabilitation. Methods An extensive literature review was performed regarding the epidemiology, pathophysiology, acute oncological management, neurological sequelae, and rehabilitation for patients with spinal cord tumors. Databases used included pubmed.gov and OVID, as well as individual journal and textbook articles. Results Access to treatment should be increased given improved survival and functional deficits for patients with spinal cord tumors. Individuals can benefit from inpatient rehabilitation programs, in spite of increased medical co-morbidity and neurological deficits. Specific areas of improvement include functionality, mood, quality of life, and survival. Adjustments to treatment plans must incorporate medical complications from cancer and its treatment, perceived quality of life, and prognosis. Conclusions Patients with spinal cord tumors who participate in rehabilitation programs show general improvement in function, mood, quality of life, and survival. Adaptations to care plans should be made to accommodate medical co-morbidities from cancer and its treatment, patient perceptions, and prognosis. PMID:23433329

  15. SPINAL SEROTONIN RECEPTOR ACTIVATION MODULATES THE EXERCISE VENTILATORY RESPONSE WITH INCREASED DEAD SPACE IN GOATS

    2008-01-01

    Small increases in respiratory dead space (VD) augment the exercise ventilatory response by a serotonin-dependent mechanism known as short-term modulation (STM). We tested the hypotheses that the relevant serotonin receptors for STM are in the spinal cord, and are of the 5-HT2-receptor subtype. After preparing adult female goats with a mid-thoracic (T6–T8) subarachnoid catheter, ventilation and arterial blood gases were measured at rest and during treadmill exercise (4.8 km/h; 5% grade) with and without an increased VD (0.2–0.3 L). Measurements were made before and after spinal or intravenous administration of a broad-spectrum serotonin receptor antagonist (methysergide, 1–2 mg total) and a selective 5-HT2-receptor antagonist (ketanserin, 5–12 mg total). Although spinal methysergide had no effect on the exercise ventilatory response in control conditions, the augmented response with increased VD was impaired, allowing PaCO2 to increase from rest to exercise. Spinal methysergide diminished both mean inspiratory flow and frequency responses to exercise with increased VD. Spinal ketanserin impaired PaCO2 regulation with increased VD, although its ventilatory effects were less clear. Intrathecal dye injections indicated CSF drug distribution was caudal to the upper cervical spinal cord and intravenous drugs at the same total dose did not affect STM. We conclude that spinal 5-HT2 receptors modulate the exercise ventilatory response with increased VD in goats. PMID:18396470

    Summary This study includes 20 patients with 21 spinal perimedullary fistulae. There were nine Type IVa (42.8%) lesions, ten Type IVb (47.6%) and two Type IVc (9.5%) lesions. The dominant arterial supply was from the anterior spinal artery (47.6%), posterior spinal artery (19%) and directly from the radiculomedullary artery (28.5%). Sixteen lesions in 15 patients were treated by endovascular route using n-butyl-2-cyanoacrylate. Endovascular treatment was not feasible in five patients. Of the ten patients with microfistulae, catheterization failed/was not attempted in 40%, complete obliteration of the lesion was seen in 60% but clinical improvement was seen in 40% of patients. Catheterization was feasible in all ten patients with macrofistulae (nine type IVb and two type IVc lesions). Complete obliteration of the lesions was seen in 60% and residue in 30%. Clinical improvement was seen in 80% and clinical deterioration in 10%. In conclusion, endovascular glue embolization is safe and efficacious in type IVb and IVc spinal perimedullary fistulae and should be considered the first option of treatment. It is also feasible in many of the type IVa lesions. PMID:24976100

    Current dogma states that meaningful recovery of function after spinal cord injury (SCI) will likely require a combination of therapeutic interventions comprised of regenerative/neuroprotective transplants, addition of neurotrophic factors, elimination of inhibitory molecules, functional sensorimotor training, and/or stimulation of paralyzed muscles or spinal circuits. We routinely use (1) peripheral nerve grafts to support and direct axonal regeneration across an incomplete cervical or complete thoracic transection injury, (2) matrix modulation with chondroitinase (ChABC) to facilitate axonal extension beyond the distal graft-spinal cord interface, and (3) exercise, such as forced wheel walking, bicycling, or step training on a treadmill. We and others have demonstrated an increase in spinal cord levels of endogenous neurotrophic factors with exercise, which may be useful in facilitating elongation and/or synaptic activity of regenerating axons and plasticity of spinal neurons below the level of injury.

    An increase in the prevalence of obesity in people with spinal cord injury can contribute to low-grade chronic inflammation and increase the risk of infection in this population. A decrease in sympathetic activity contributes to immunosuppression due to the lower activation of immune cells in the blood. The effects of physical exercise on inflammatory parameters in individuals with spinal cord injury have not been well described. We conducted a review of the literature published from 1974 to 2012. This review explored the relationships between low-grade inflammation, spinal cord injury, and exercise to discuss a novel mechanism that might explain the beneficial effects of exercise involving an increase in catecholamines and cytokines in people with spinal cord injury.

    Exercise-induced cortical plasticity is associated with improved functional outcome after brain or nerve injury. Exercise also improves functional outcomes after spinal cord injury, but its effects on cortical plasticity are not known. The goal of this investigation was to study the effect of moderate exercise (treadmill locomotion, 3 min/d, 5 d/week) on the somatotopic organization of forelimb and hindlimb somatosensory cortex (SI) after neonatal thoracic transection. We used adult rats spinalized as neonates because some of these animals develop weight-supported stepping, and, therefore, the relationship between cortical plasticity and stepping could also be examined. Acute, single-neuron mapping was used to determine the percentage of cortical cells responding to cutaneous forelimb stimulation in normal, spinalized, and exercised spinalized rats. Multiple single-neuron recording from arrays of chronically implanted microwires examined the magnitude of response of these cells in normal and exercised spinalized rats. Our results show that exercise not only increased the percentage of responding cells in the hindlimb SI but also increased the magnitude of the response of these cells. This increase in response magnitude was correlated with behavioral outcome measures. In the forelimb SI, neonatal transection reduced the percentage of responding cells to forelimb stimulation, but exercise reversed this loss. This restoration in the percentage of responding cells after exercise was accompanied by an increase in their response magnitude. Therefore, the increase in responsiveness of hindlimb SI to forelimb stimulation after neonatal transection and exercise may be due, in part, to the effect of exercise on the forelimb SI.

    We asked whether specific inspiratory muscle training (IMT) improves respiratory structure and function and peak exercise responses in highly trained athletes with cervical spinal cord injury (SCI). Ten Paralympic wheelchair rugby players with motor-complete SCI (C5-C7) were paired by functional classification then randomly assigned to an IMT or placebo group. Diaphragm thickness (B-mode ultrasonography), respiratory function [spirometry and maximum static inspiratory (PI ,max ) and expiratory (PE ,max ) pressures], chronic activity-related dyspnea (Baseline and Transition Dyspnea Indices), and physiological responses to incremental arm-crank exercise were assessed before and after 6 weeks of pressure threshold IMT or sham bronchodilator treatment. Compared to placebo, the IMT group showed significant increases in diaphragm thickness (P = 0.001) and PI ,max (P = 0.016). There was a significant increase in tidal volume at peak exercise in IMT vs placebo (P = 0.048) and a strong trend toward an increase in peak work rate (P = 0.081, partial eta-squared = 0.33) and peak oxygen uptake (P = 0.077, partial eta-squared = 0.34). No other indices changed post-intervention. In conclusion, IMT resulted in significant diaphragmatic hypertrophy and increased inspiratory muscle strength in highly trained athletes with cervical SCI. The strong trend, with large observed effect, toward an increase in peak aerobic performance suggests IMT may provide a useful adjunct to training in this population. PMID:23530708

    Our recent terminal experiments revealed that administration of a single train of repetitive spinal electromagnetic stimulation (sEMS; 35 min) enhanced synaptic plasticity in spinal circuitry following lateral hemisection spinal cord injury. In the current study, we have examined effects of repetitive sEMS applied as a single train and chronically (5 wk, every other day) following thoracic T10 contusion. Chronic studies involved examination of systematic sEMS administration alone and combined with exercise training and transgene delivery of neurotrophin [adeno-associated virus 10-neurotrophin 3 (AAV10-NT3)]. Electrophysiological intracellular/extracellular recordings, immunohistochemistry, behavioral testing, and anatomical tracing were performed to assess effects of treatments. We found that administration of a single sEMS train induced transient facilitation of transmission through preserved lateral white matter to motoneurons and hindlimb muscles in chronically contused rats with effects lasting for at least 2 h. These physiological changes associated with increased immunoreactivity of GluR1 and GluR2/3 glutamate receptors in lumbar neurons. Systematic administration of sEMS alone for 5 wk, however, was unable to induce cumulative improvements of transmission in spinomuscular circuitry or improve impaired motor function following thoracic contusion. Encouragingly, chronic administration of sEMS, followed by exercise training (running in an exercise ball and swimming), induced the following: 1) sustained strengthening of transmission to lumbar motoneurons and hindlimb muscles, 2) better retrograde transport of anatomical tracer, and 3) improved locomotor function. Greatest improvements were seen in the group that received exercise combined with sEMS and AAV-NT3. PMID:26424579

    We report the outcome of 30 patients with multilevel noncontiguous spinal fractures treated between 2000 and 2005. Ten cases were treated conservatively (group A), eight cases were operated on at only one level (group B), and 12 cases were treated surgically at both levels (group C). All cases were followed up for 14–60 months (mean 32 months). Initial mobilisation with a wheelchair or crutches in group A was 9.2±1.1 weeks, which was significantly longer than groups B and C with 6.8±0.7 weeks and 3.1±0.4 weeks, respectively. Operative time and blood loss in group C were significantly more than group B. The neurological deficit improved in six cases in group A (60%), six in group B (75%) and eight in group C (80%). Correction of kyphotic deformity was significantly superior in groups C and B at the operated level, and increasing deformity occurred in groups A and B at the non-operated level. From the results we believe that three treatment strategies were suitable for multilevel noncontiguous spinal fractures, and individualised treatment should be used in these patients. In the patients treated surgically, the clinical and radiographic outcomes are much better. PMID:17043863

Any intervention that: 1) reduces ventilatory demands; 2) reduces ventilatory impedance; or 3) improves inspiratory muscle function, may relieve dyspnoea. Reduced ventilatory demand may be obtained by reducing metabolic load. Supplemental oxygen during exercise reduces exertional breathlessness and improves exercise tolerance, the decrease in dyspnoea being proportional to decrease in minute ventilation. Reduced ventilatory demand may also be obtained by decreasing the central drive. Opiates have been shown to decrease minute ventilation at rest and during submaximal exercise. They can alter the central processing of neural signals within the central nervous system to reduce sensations associated with breathing. Contrastingly, no consistent improvement in dyspnoea (versus placebo) has been shown with anxolytics. Decreasing central drive may also be obtained by altering pulmonary afferent information. Interventions that alter transmittal of afferent information to the central controller, potentially reduce dyspnoea. Reduction of ventilatory impedance is obtained by administering B2, anticholinergics or theophylline. B2 and anticholinergics act by modulating the increase in operational lung volumes and the inspiratory muscle effort during exercise. The mechanism by which theophylline relieves dyspnoea is probably related to a mechanism other than its bronchodilation alone. Alterations in respiratory muscle function are currently being detected in patients with chronic obstructive pulmonary disease, due to alteration in respiratory muscle energy balance. Nutritional repletion may improve respiratory muscle function but uncertainty remains as to whether nutritional repletion may relieve dyspnoea. The cumulative benefit of interventions targeting the pathophysiologic mechanism of dyspnoea must be identified for optimum treatment of patients

    Purpose: To identify the prognostic factors for spinal cord astrocytoma and determine the effects of surgery and radiotherapy on outcome. Methods and Materials: This retrospective study reviewed the cases of consecutive patients with spinal cord astrocytoma treated at Mayo Clinic Rochester between 1962 and 2005. Results: A total of 136 consecutive patients were identified. Of these 136 patients, 69 had pilocytic and 67 had infiltrative astrocytoma. The median follow-up for living patients was 8.2 years (range, 0.08-37.6), and the median survival for deceased patients was 1.15 years (range, 0.01-39.9). The extent of surgery included incisional biopsy only (59%), subtotal resection (25%), and gross total resection (16%). Patients with pilocytic tumors survived significantly longer than those with infiltrative astrocytomas (median overall survival, 39.9 vs. 1.85 years; p < 0.001). Patients who underwent resection had a worse, although nonsignificant, median survival than those who underwent biopsy only (pilocytic, 18.1 vs. 39.9 years, p = 0.07; infiltrative, 19 vs. 30 months, p = 0.14). Postoperative radiotherapy, delivered in 75% of cases, gave no significant survival benefit for those with pilocytic tumors (39.9 vs. 18.1 years, p = 0.33) but did for those with infiltrative astrocytomas (24 vs. 3 months; Wilcoxon p = 0.006). On multivariate analysis, pilocytic histologic type, diagnosis after 1984, longer symptom duration, younger age, minimal surgical extent, and postoperative radiotherapy predicted better outcome. Conclusion: The results of our study have shown that histologic type is the most important prognostic variable affecting the outcome of spinal cord astrocytomas. Surgical resection was associated with shorter survival and thus remains an unproven treatment. Postoperative radiotherapy significantly improved survival for patients with infiltrative astrocytomas but not for those with pilocytic tumors.

    [Purpose] We examined the impact of exercise on the expression pattern of nerve growth factor in the spinal cord of rats with induced osteoarthritis of the knee joint. [Subjects and Methods] To produce monosodium iodoacetate-induced arthritis, rats were administered 3 mg/50 µL monosodium iodoacetate through the interarticular space of the right knee. The animals were randomly divided into four groups: rats sacrificed 3 weeks after 0.9% saline solution injection (shame group, n = 10), rats sacrificed 3 weeks after monosodium iodoacetate injection (control group, n = 10), rats with 4 weeks rest from 3 weeks after monosodium iodoacetate injection (no exercise group, n = 10), and rats with 4 weeks treadmill training from 3 weeks after monosodium iodoacetate injection (exercise group, n = 10). Serial coronal sections of the lumbar spine were cut and processed for immunohistochemistry. [Results] The expression of nerve growth factor was significantly increased in the EG compared with the SG, CG, and NEG. [Conclusion] Increased nerve growth factor expression in the spinal cord due to exercise-induced stimulation can be effective in treating chronic pain. Such treatment will contribute not only to improving the joint function of patients with chronic pain but also their quality of life. PMID:26357438

    The heat shock protein 72 (HSP 72) is a universal marker of stress protein whose expression can be induced by physical exercise. Here we report that, in a localized model of spinal cord injury (SCI), exercised rats (given pre-SCI exercise) had significantly higher levels of neuronal and astroglial HSP 72, a lower functional deficit, fewer spinal cord contusions, and fewer apoptotic cells than did non-exercised rats. pSUPER plasmid expressing HSP 72 small interfering RNA (SiRNA-HSP 72) was injected into the injured spinal cords. In addition to reducing neuronal and astroglial HSP 72, the (SiRNA-HSP 72) significantly attenuated the beneficial effects of exercise preconditioning in reducing functional deficits as well as spinal cord contusion and apoptosis. Because exercise preconditioning induces increased neuronal and astroglial levels of HSP 72 in the gray matter of normal spinal cord tissue, exercise preconditioning promoted functional recovery in rats after SCI by upregulating neuronal and astroglial HSP 72 in the gray matter of the injured spinal cord. We reveal an important function of neuronal and astroglial HSP 72 in protecting neuronal and astroglial apoptosis in the injured spinal cord. We conclude that HSP 72-mediated exercise preconditioning is a promising strategy for facilitating functional recovery from SCI. PMID:25334068

    Perineuronal nets (PNNs) are lattice like structures which encapsulate the cell body and proximal dendrites of many neurons and are thought to be involved in regulating synaptic plasticity. It is believed that exercise can enhance the plasticity of the Central Nervous System (CNS) in healthy and dysfunctional states by shifting the balance between plasticity promoting and plasticity inhibiting factors in favor of the former. Recent work has focused on exercise effects on trophic factors but its effect on other plasticity regulators is poorly understood. In the present study we investigated how exercise regulates PNN expression in the lumbar spinal cord and areas of the brain associated with motor control and learning and memory. Adult, female Sprague-Dawley rats with free access to a running wheel for 6 weeks had significantly increased PNN expression in the spinal cord compared to sedentary rats (PNN thickness around motoneurons, exercise=15.75±0.63μm, sedentary=7.98±1.29μm, p<0.01). Conversely, in areas of the brain associated with learning and memory there was a significant reduction in perineuronal net expression (number of neurons with PNN in hippocampus CA1-exercise 21±0.56 and sedentary 24±0.34, p<0.01, thickness-exercised=2.37±0.13μm, sedentary=4.27±0.21μm; p<0.01). Our results suggest that in response to exercise, PNNs are differentially regulated in select regions of the CNS, with a general decreased expression in the brain and increased expression in the lumbar spinal cord. This differential expression may indicate different regulatory mechanisms associated with plasticity in the brain compared to the spinal cord. PMID:25526898

    Objective The purpose of this study was to determine if thoracolumbar chiropractic manipulative therapy (CMT) had an immediate impact on exercise performance by measuring blood lactate concentration, exercise heart rate, and rating of perceived exertion during a treadmill-based graded exercise test (GXT). Methods Ten healthy, asymptomatic male and 10 female college students (age = 27.5 ± 3.7 years, height = 1.68 ± 0.09 m, body mass = 71.3 ± 11.6 kg: mean ± SD) were equally randomized into an AB:BA crossover study design. Ten participants were in the AB group, and 10 were in the BA group. The study involved 1 week of rest in between each of the 2 conditions: A (prone Diversified T12-L1 CMT) vs B (no CMT). Participants engaged in a treadmill GXT 5 minutes after each week's condition (A or B). Outcome measures were blood lactate concentration, exercise heart rate, and rating of perceived exertion monitored at the conclusion of each 3-minute stage of the GXT. The exercise test continued until the participant achieved greater than 8 mmol/L blood lactate, which correlates with maximal to near-maximal exercise effort. A dependent-samples t test was used to make comparisons between A and B conditions related to exercise performance. Results No statistically significant difference was shown among any exercise response dependent variables in this study. Conclusions The results of this research preliminarily suggest that CMT to T12-L1 does not immediately impact exercise performance during a treadmill-based GXT using healthy college students.

    Purpose Tuberculosis can be responsible for extensive spinal lesions. Despite the efficacy of medical treatment, surgery is indicated to avoid or correct significant deformity, treat spinal instability, prevent neurological compromise, and to eradicate an extensive tuberculous abscess. In this paper we present our experience in the surgical management of spinal tuberculosis complicated with large abscess. Patients and Methods Fifteen patients with spinal tuberculosis complicated with extensive abscess were identified; and nine of those patients had extension of the infection into the epidural space. The average age at treatment was 34 years old. Seven patients had thoracic infection, seven patients had lumbar infection and one had thoracolumbar infection. Six patients had neurological deficit at presentation. All patients were surgically treated with abscess debridement, spinal stabilization and concurrent antituberculous chemotherapy. A single anterior surgical approach was used in three cases, a posterior approach was used in four others and a combined approach was performed in eight patients. Results Surgical management allowed for effective abscess debridement and sspinal stabilization in this cohort. In combination with antituberculous drugs, surgical treatment resulted in infection eradication and bone fusion in all patients at 24 month average follow-up. Satisfactory neurological outcomes with improved American Spinal Injury Association (ASIA) scores were observed in 100% of patients. Conclusion Surgical treatment for spinal tuberculosis abscess can lead to satisfactory clinical outcomes. PMID:25328472

    Objectives. This systematic review was conducted to examine the effects of exercise on spinal deformities and quality of life in patients with adolescent idiopathic scoliosis (AIS). Data Sources. Electronic databases, including PubMed, CINAHL, Embase, Scopus, Cochrane Register of Controlled Trials, PEDro, and Web of Science, were searched for research articles published from the earliest available dates up to May 31, 2015, using the key words “exercise,” “postural correction,” “posture,” “postural curve,” “Cobb's angle,” “quality of life,” and “spinal deformities,” combined with the Medical Subject Heading “scoliosis.” Study Selection. This systematic review was restricted to randomized and nonrandomized controlled trials on AIS published in English language. The quality of selected studies was assessed by the PEDro scale, the Cochrane Collaboration's tool, and the Grading of Recommendations Assessment, Development, and Evaluation System (GRADE). Data Extraction. Descriptive data were collected from each study. The outcome measures of interest were Cobb angle, trunk rotation, thoracic kyphosis, lumbar kyphosis, vertebral rotation, and quality of life. Data Synthesis. A total of 30 studies were assessed for eligibility. Six of the 9 selected studies reached high methodological quality on the PEDro scale. Meta-analysis revealed moderate-quality evidence that exercise interventions reduce the Cobb angle, angle of trunk rotation, thoracic kyphosis, and lumbar lordosis and low-quality evidence that exercise interventions reduce average lateral deviation. Meta-analysis revealed moderate-quality evidence that exercise interventions improve the quality of life. Conclusions. A supervised exercise program was superior to controls in reducing spinal deformities and improving the quality of life in patients with AIS. PMID:26583083

    Maximum oxygen consumption, maximum heart rate and maximum ventilation during cycle ergometer exercise were studied in individuals with spinal muscular atrophy (N = 8) and limb-girdle dystrophy (N = 8). The limiting factors in aerobic power may be related to loss of functional muscular mass rather than to changes in the oxygen transport system. There was no correlation between VO2 max values and muscle strength as determined by a manual test of the affected muscles recruited for bicycle exercise. The results, therefore, do not support the possibility of a correlation between these indices previously proposed on the basis of clinical evidence. PMID:3452446

    Further progress in the treatment of the longitudinal spinal cord injury has been made. In an inverted translational study, it has been demonstrated that return of sensory function can be achieved by bypassing the avulsed dorsal root ganglion neurons. Dendritic growth from spinal cord sensory neurons could replace dorsal root ganglion axons and re-establish a reflex arch. Another research avenue has led to the development of adjuvant therapy for regeneration following dorsal root to spinal cord implantation in root avulsion injury. A small, lipophilic molecule that can be given orally acts on the retinoic acid receptor system as an agonist. Upregulation of dorsal root ganglion regenerative ability and organization of glia reaction to injury were demonstrated in treated animals. The dual effect of this substance may open new avenues for the treatment of root avulsion and spinal cord injuries. PMID:27602018

    Study Design Retrospective review. Purpose We retrospectively reviewed our patients with ankylosing spondylitis (AS) to identify their patterns of spinal fractures to help clarify management strategies and the morbidity and mortality rates associated with this group of patients. Overview of Literature Because of the brittleness of bone and long autofused spinal segments in AS, spinal fractures are common even after minor trauma and often associated with overt instability. Methods Between January 1, 1998 and March 2011, 30 patients (23 males, 7 females; mean age, 70.43 years; range, 45 to 95 years) with the radiographic diagnosis of AS of the spinal column had 42 fractures. Eight patients presented with significant trauma, 17 after falls, and 5 after minor falls or no recorded trauma. Eleven patients presented with a neurological injury, ranging from mild sensory loss to quadriplegia. Results There were 16 compression and 10 transverse fractures, two Jefferson's fractures, one type II and two type III odontoid process fractures, and five fractures of the posterior spinal elements (including lamina and/or facet, three spinous process fractures, three transverse process fractures). Twenty-four fractures affected the craniocervical junction and/or cervical vertebrae, 17 were thoracic, and one involved the lumbar spine. The most affected vertebrae were C6 and T10. The mean follow-up was 29.9 months. One patient was lost to follow-up. Eighteen patients were treated conservatively with bed rest and bracing. Twelve patients underwent surgery for spinal stabilization either with an anterior, posterior or combined approach. Conclusions Nonsurgical treatment can be considered especially in the elderly patients with AS and spinal trauma but without instability or major neurological deficits. The nonfusion rate in conservatively treated patients is low. When treatment is selected for patients with spinal fractures and AS, the pattern of injury must be considered and the need

    This review aims to provide a comprehensive overview of the literature on the use of exercise for migraine treatment with regard to its efficacy, mechanism of action and role in practice. Many randomized studies have reported the efficacy of prophylactic treatment of migrane with medications such as beta blockers or antiepileptic drugs. Studies on alternative approaches, like aerobic exercise and biofeedback, are however limited but also considered to be effective. Scientific databases were searched with keywords "exercise" and "migraine". The resulting publications were gathered, examined and discussed throughly. Past studies had limitations and were few in number, but more recent randomized controlled studies have concretely provided level of evidence about the effectiveness of exercise in prophylactic treatment of migraine. Core properties of exercise like intensity, duration, frequency, type and warming up period are required to be monitored while treating migraine to increase the beneficial effects and, also to prevent injuries and side effects which may include exertional headache. Isometric neck exercise is helpful when the migraine is accompanied by neck pain. Patient population with low beta endorphin level in blood, high physical fitness and high motivation receives significant benefits from the exercise treatment. The action of exercise on migraine is in general related to neurochemical factors, psychological states and increase in cardivascular and cerebrovascular fitness. Considering its effectiveness and minimal side effects, migraine patients should often be encouraged to practice physical exercise with intensity, frequency and duration that should be carefully instituted to achieve the most beneficial outcome while preventing potential injuries and side effects.

    2010-01-01

    Abstract The highly debilitating nature of spinal cord injuries has provided much inspiration for the design of novel biomaterials that can stimulate cellular regeneration and functional recovery. Many experts agree that the greatest hope for treatment of spinal cord injuries will involve a combinatorial approach that integrates biomaterial scaffolds, cell transplantation, and molecule delivery. This manuscript presents a comprehensive review of biomaterial-scaffold design strategies currently being applied to the development of nerve guidance channels and hydrogels that more effectively stimulate spinal cord tissue regeneration. To enhance the regenerative capacity of these two scaffold types, researchers are focusing on optimizing the mechanical properties, cell-adhesivity, biodegradability, electrical activity, and topography of synthetic and natural materials, and are developing mechanisms to use these scaffolds to deliver cells and biomolecules. Developing scaffolds that address several of these key design parameters will lead to more successful therapies for the regeneration of spinal cord tissue. PMID:19698073

    The interactions between a prior program of regular exercise and the development of experimental autoimmune encephalomyelitis (EAE)-mediated responses were evaluated. In the exercised EAE mice, although there was no effect on infiltrated cells, the cytokine and derived neurotrophic factor (BDNF) levels were altered, and the clinical score was attenuated. Although, the cytokine levels were decreased in the brain and increased in the spinal cord, BDNF was elevated in both compartments with a tendency of lesser demyelization volume in the spinal cord of the exercised EAE group compared with the unexercised.

    Exercise training is an underused intervention in paediatric healthcare. This is surprising, since initial evidence demonstrates its effectiveness and safety; furthermore it confers socioeconomic benefits for healthcare systems. Pilot studies have assessed and confirmed the feasibility of exercise training in many paediatric disease settings. However, more research is needed to understand the pathophysiology, quantify treatment effects and monitor outcomes. A concerted effort from researchers, health professionals and police makers will be necessary to make exercise training an evidence-based and cost-effective intervention in paediatric care.

    Objective: To provide a systematic review of the studies assessing exercise training and inspiratory muscle training (IMT) in individuals for the improved respiratory function of patients with spinal cord injury (SCI). Methods: Thirteen studies (5 exercise training, 8 IMT) were identified. Articles were scored for their methodological quality using the Physiotherapy Evidence Database scores and Downs and Black tools for randomized and nonrandomized studies, respectively. Conclusions were based on the most rigorously executed studies using Sackett's levels of evidence. Results: Study comparison was compromised by diverse research designs; small sample sizes; and heterogeneity of studied populations, protocols, and outcome measures. Based on current literature, there is level 2 evidence supporting exercise training as an intervention to improve respiratory strength and endurance and level 4 evidence to support exercise training as an intervention that might improve resting and exercising respiratory function in people with SCI. There is level 4 evidence to support IMT as an intervention that might decrease dyspnea and improve respiratory function in people with SCI. Conclusions: There are insufficient data to strongly support the use of exercise training or IMT for improved respiratory function in people with SCI. There is some evidence of efficacy of both regimens; however, the evidence is not of the best possible quality. PMID:19086707

    Previous studies found that prostaglandins in skeletal muscle play a role in evoking the exercise pressor reflex; however the role played by prostaglandins in the spinal transmission of the reflex is not known. We determined, therefore, whether or not spinal blockade of cyclooxygenase (COX) activity and/or spinal blockade of endoperoxide receptor (EP) 2 or EP4 receptors attenuated the exercise pressor reflex in decerebrate rats. We first established that intrathecal doses of a non-specific COX inhibitor Ketorolac (100ug in 10ul), a COX-2 specific inhibitor Celecoxib (100μg in 10μl), an EP2 antagonist PF-04418948 (10μg in 10μl), and an EP4 antagonist L-161,982 (4μg in 10μl) effectively attenuated the pressor responses to intrathecal injections of Arachidonic Acid (100μg in 10μl), EP2 agonist Butaprost (4ng in 10 μl), and EP4 agonist TCS 2510 (6.25μg in 2.5 μl), respectively. Once effective doses were established, we statically contracted the hindlimb before and after intrathecal injections of Ketorolac, Celecoxib, the EP2 antagonist and the EP4 antagonist. We found that Ketorolac significantly attenuated the pressor response to static contraction (before Ketorolac: 23±5 mmHg, after Ketorolac 14±5 mmHg; p<0.05) whereas Celecoxib had no effect. We also found that 8μg of L-161,982, but not 4 μg of L-161,982, significantly attenuated the pressor response to static contraction (before L-161,982: 21±4 mmHg, after L-161,982 12±3 mmHg; p<0.05), whereas PF-04418948 (10μg) had no effect. We conclude that spinal COX-1, but not COX-2, plays a role in evoking the exercise pressor reflex, and that the spinal prostaglandins produced by this enzyme are most likely activating spinal EP4 receptors, but not EP2 receptors.

    Purpose: As the spinal cord tolerance often precludes reirradiation with conventional techniques, local recurrence within a previously irradiated field presents a treatment challenge. Methods and Materials: We retrospectively reviewed 51 lesions in 42 patients treated from 2002 to 2008 whose spinal metastases recurred in a previous radiation field (median previous spinal cord dose of 40 Gy) and were subsequently treated with stereotactic radiosurgery (SRS). Results: SRS was delivered to a median marginal dose of 20 Gy (range, 10-30 Gy) in 1-5 fractions (median, 2), targeting a median tumor volume of 10.3 cm{sup 3} (range, 0.2-128.6 cm{sup 3}). Converting the SRS regimens with the linear quadratic model ({alpha}/{beta} = 3), the median spinal cord maximum single-session equivalent dose (SSED) was 12.1 Gy{sub 3} (range, 4.7-19.3 Gy{sub 3}). With a median follow-up of 7 months (range, 2-47 months), the Kaplan-Meier local control and overall survival rates at 6/12 months were 87%/73% and 81%/68%, respectively. A time to retreatment of {<=}12 months and the combination of time to retreatment of {<=}12 months with an SSED of <15 Gy{sub 10} were significant predictors of local failure on univariate and multivariate analyses. In patients with a retreatment interval of <12 months, 6/12 month local control rates were 88%/58%, with a SSED of >15 Gy{sub 10}, compared to 45%/0% with <15 Gy{sub 10}, respectively. One patient (2%) experienced Grade 4 neurotoxicity. Conclusion: SRS is safe and effective in the treatment of spinal metastases recurring in previously irradiated fields. Tumor recurrence within 12 months may correlate with biologic aggressiveness and require higher SRS doses (SSED >15 Gy{sub 10}). Further research is needed to define the partial volume retreatment tolerance of the spinal cord and the optimal target dose.

    Postoperative pain relief has the aim to provide patient subjective comfort, to inhibit neuroendocrine and metabolic responses to surgical injury and to enhance restoration of function by allowing the patient to breathe, cough, move more easily and to begin enteral nutrition. Opioid analgesics, independently from the route of administration, are unable to provide all this. In addition to spinal opioids other drugs, such as local anesthetics, alpha 2-agonists and cholinergic drugs, may produce an antinociceptive effect when administered by spinal route. All these drugs may be administered in combination between them, realising the so called "balanced spinal analgesia". The aim of this study is to analyse the available methods for the evaluation of pharmacological interactions, the types of interaction among different spinal antinociceptive drugs and the role of balanced spinal analgesia in the treatment of postoperative pain. Analysis of the presented data shows that the spinal synergism between opioids-local anesthetics and opioids-alpha 2-agonists can be useful in the treatment of postoperative pain, because these drug combinations are able to provide a satisfactory pain control at low doses with a reduction of the adverse effects. Furthermore, the combined use of opioids-local anesthetics proved to be effective also in abolishing postoperative incident pain and in inhibiting neuroendocrine and metabolic responses to surgical injury. Especially in high risk patients this is related to a better outcome. Finally, even if the synergism between cholinergic drugs with opioids or a2-agonists have been proved, at the moment their use in man by spinal route in the treatment of postoperative pain is not advisable.

    [Purpose] The purpose of this study was to collect basic data regarding the prevention of spinal and pelvic deformities by investigating the spinal shape and muscular function characteristics of imbalance reduction and functional improvement following asymmetric activities. [Subjects and Methods] The subjects were 14 archery athletes who mostly perform unilateral motion with spinal and pelvic pain, and 19 healthy subjects. All the participants were evaluated using spinal structure analysis and for 60°/sec isokinetic muscular strength of the trunk. [Results] Between the two groups, there were significant differences in the interaction effect of trunk inclination deformities, and flexor and extensor 60°/sec isokinetic muscular strength of the trunk. Also, the main effects of gender comparison showed significant differences in the trunk inclination deformities, pelvic rotation deformities, lordosis angles, and flexor and extensor 60 ˚/sec isokinetic muscular strengths of the trunk. [Conclusion] The basic data obtained in this study can be used to help develop a strategic exercise program for improving unilateral movement and malalignment of the spine and pelvis. PMID:27134369

    The authors describe the changes occurring in the spinal cord of rats subjected to crush injury of the sciatic nerve followed by low-power laser irradiation of the injured nerve. Such laser treatment of the crushed peripheral nerve has been found to mitigate the degenerative changes in the corresponding neurons of the spinal cord and induce proliferation of neuroglia both in astrocytes and oligodendrocytes. This suggests a higher metabolism in neurons and a better ability for myelin production under the influence of laser treatment.

    [Purpose] This study examined spinal shape in professional golfers with chronic back pain, and analyzed the effects of a 4-week regimen of semi-weekly manipulation and corrective core exercises on spinal shape. [Subjects] Two golfers with chronic back pain. [Methods] The pelvis and spinal vertebrae were corrected using the Thompson “drop” technique. Angle and force were adjusted to place the pelvis, lumbar spine, and thoracic vertebrae in neutral position. The technique was applied twice weekly after muscle massage in the back and pelvic areas. The golfers performed corrective, warmup stretching exercises, followed by squats on an unstable surface using the Togu ball. They then used a gym ball for repetitions of hip rotation, upper trunk extension, sit-ups, and pelvic anterior-posterior, pelvic left-right, and trunk flexion-extension exercises. The session ended with cycling as a cool-down exercise. Each session lasted 60 minutes. [Results] The difference in height was measured on the left and right sides of the pelvic bone. The pelvic tilt changed significantly in both participants after the 4-week program. [Conclusion] In golfers, core muscles are critical and are closely related to spinal deformation. Core strengthening and spinal correction play a pivotal role in the correction of spinal deformation. PMID:26504350

    Over the past 2 decades, great strides have been made in the field of exercise-oncology research, particularly with breast cancer. This area of research is particularly important since there are >2.8 million breast cancer survivors who are in need of an intervention that can offset treatment-related side effects. Noticeable reductions in physical fitness (ie, cardiopulmonary fitness and muscular strength), negative changes in body composition (ie, increase in body mass, decrease in lean body mass, and increase in fat mass), increased fatigue, depression, or anxiety are some of the common side effects of cancer treatments that negatively impact overall quality of life and increase the risk for the development of comorbidities. Exercise plays a vital role in improving cardiopulmonary function, psychological events, muscular strength, and endurance in breast cancer survivors, and thus should be considered as a key factor of lifestyle intervention to reverse negative treatment-related side effects. The purpose of this review is to address current perspectives on the benefits of aerobic and resistance exercise after breast cancer treatments. This review is focused on the well-established benefits of exercise on physical and emotional well-being, bone health, lymphedema management, and the postulated benefits of exercise on risk reduction for recurrence of breast cancer.

    Physical exercise promotes neural plasticity in the brain of healthy subjects and modulates pathophysiological neural plasticity after sensorimotor loss, but the mechanisms of this action are not fully understood. After spinal cord injury, cortical reorganization can be maximized by exercising the non-affected body or the residual functions of the affected body. However, exercise per se also produces systemic changes - such as increased cardiovascular fitness, improved circulation and neuroendocrine changes - that have a great impact on brain function and plasticity. It is therefore possible that passive exercise therapies typically applied below the level of the lesion in patients with spinal cord injury could put the brain in a more plastic state and promote cortical reorganization. To directly test this hypothesis, we applied passive hindlimb bike exercise after complete thoracic transection of the spinal cord in adult rats. Using western blot analysis, we found that the level of proteins associated with plasticity - specifically ADCY1 and BDNF - increased in the somatosensory cortex of transected animals that received passive bike exercise compared to transected animals that received sham exercise. Using electrophysiological techniques, we then verified that neurons in the deafferented hindlimb cortex increased their responsiveness to tactile stimuli delivered to the forelimb in transected animals that received passive bike exercise compared to transected animals that received sham exercise. Passive exercise below the level of the lesion, therefore, promotes cortical reorganization after spinal cord injury, uncovering a brain-body interaction that does not rely on intact sensorimotor pathways connecting the exercised body parts and the brain.

    Objective To determine the safety and efficacy of a home-based functional exercise program in spinal and bulbar muscular atrophy (SBMA). Methods Subjects were randomly assigned to participate in 12 weeks of either functional exercises (intervention) or a stretching program (control) at the National Institutes of Health in Bethesda, MD. A total of 54 subjects enrolled, and 50 completed the study with 24 in the functional exercise group and 26 in the stretching control group. The primary outcome measure was the Adult Myopathy Assessment Tool (AMAT) total score, and secondary measures included total activity by accelerometry, muscle strength, balance, timed up and go, sit-to-stand test, health-related quality of life, creatine kinase, and insulin-like growth factor-1. Results Functional exercise was well tolerated but did not lead to significant group differences in the primary outcome measure or any of the secondary measures. The functional exercise did not produce significantly more adverse events than stretching, and was not perceived to be difficult. To determine whether a subset of the subjects may have benefited, we divided them into high and low functioning based on baseline AMAT scores and performed a post hoc subgroup analysis. Low-functioning individuals receiving the intervention increased AMAT functional subscale scores compared to the control group. Interpretation Although these trial results indicate that functional exercise had no significant effect on total AMAT scores or on mobility, strength, balance, and quality of life, post hoc findings indicate that low-functioning men with SBMA may respond better to functional exercises, and this warrants further investigation with appropriate exercise intensity.

    Isometric muscle contraction (static exercise) induces circulatory response. Static exercise in individuals with thoracic spinal cord injury (TSCI) induces cardiovascular response and blood redistribution to the non-exercising muscles. The aim of our study was to determine the circulatory response during arm static exercise in individuals with TSCI and able-bodied (AB) controls. Mean blood pressure (MBP), heart rate (HR), cardiac output (CO), leg skin blood flow (SBF), and leg muscle blood flow (MBF) were recorded noninvasively, total peripheral resistance (TPR) was estimated by dividing MBP by CO, and hormonal changes were measured before, during and after static 35% maximal voluntary contraction (MVC) of the arm flexor muscles in seven male individuals with TSCI (T7-T11) and seven age-comparable AB control (32.2 ± 7.6 and 31.0 ± 4.7 years, respectively). The 35% MVC was similar in TSCI and AB individuals (107.3 ± 28.2 and 101.0 ± 22.5 N, respectively). HR, CO, MBP, TPR, SBF and MBF increased in both groups during arm static exercise. Plasma epinephrine concentration increased during arm static exercise in AB controls only (P < 0.05). Circulation to leg muscles was similar in TSCI and AB individuals and the lack of sympathetic vasoconstriction in the paralyzed leg area did not alter the cardiovascular responses during 35% MVC of arm static exercise. We conclude that sympathetic vasoconstriction in the resting leg area did not contribute to the pressor reflex during 35% MVC of arm static exercise. PMID:21656231

[Subjects] The subjects were randomly allocated to an aqua group (n=10) and a land group (n=10). [Methods] Both groups trained for 60 minutes, 3 times a week for 8 weeks. Pulmonary function was assessed by measuring the forced vital capacity (FVC), forced expiratory flow rate (FER), force expiratory volume at one second (FEV1) and force expiratory volume at one second/forced vital capacity (FEV1/FVC). [Results] Following the intervention, the aqua group showed significant changes in FVC, FER, FEV1, and FEV1/FVC. The land group showed only significant differences FER. [Conclusion] The results of this study suggest the effects on the aqua group were significantly higher than those on the land group in patients with spinal cord injury. PMID:24926136

    In a 43-yr-old male subject with a chronic T3 AIS A spinal cord injury, the acute cardiorespiratory responses to active upper-extremity exercise alone and combined active-arm passive-leg exercise (AAPLE) were investigated, along with the cardiorespiratory, cardiac, vascular, and body composition responses to a 6-wk AAPLE interval training intervention. AAPLE elicited superior acute maximal cardiorespiratory responses compared with upper-extremity exercise alone. In response to a 6-wk interval training regimen, AAPLE caused a 25% increase in peak oxygen uptake, a 10% increase in resting stroke volume, and a 4-fold increase in brachial artery blood flow. Conversely, there were no changes in femoral arterial function, body composition, or bone mineral density in response to training. As a potential clinical intervention, AAPLE may be advantageous over other forms of currently available exercise, owing to the minimal setup time and cost involved and the nonreliance on specialized equipment that is required for other exercise modalities.

    Spinal cord injury (SCI) impaired sensory fiber transmission leads to chronic, debilitating neuropathic pain. Sensory afferents are responsive to neurotrophic factors, molecules that are known to promote survival and maintenance of neurons, and regulate sensory neuron transduction of peripheral stimuli. A subset of primary afferent fibers responds only to the glial cell-line derived neurotrophic factor (GDNF) family of ligands (GFLs) and are non-peptidergic. In peripheral nerve injury models, restoration of GDNF or artemin (another GFL) to pre-injury levels within the spinal cord attenuates neuropathic pain. One noninvasive approach to increase the levels of GFLs in the spinal cord is through exercise (Ex), and to date exercise training is the only ameliorative, nonpharmacological treatment for SCI-induced neuropathic pain. The purpose of this study was three fold: 1) to determine whether exercise affects the onset of SCI-induced neuropathic pain; 2) to examine the temporal profile of GDNF and artemin in the dorsal root ganglia and spinal cord dorsal horn regions associated with forepaw dermatomes after SCI and Ex; and 3) to characterize GFL-responsive sensory fiber plasticity after SCI and Ex. Adult, female, Sprague-Dawley rats received a moderate, unilateral spinal cord contusion at C5. A subset of rats was exercised (SCI+Ex) on automated running wheels for 20 minutes, 5d/week starting at 5 days post injury (dpi), continuing until 9 or 37 dpi. Hargreaves' and von Frey testing was performed preoperatively and weekly post SCI. Forty-two percent of rats in the unexercised group exhibited tactile allodynia of the forepaws while the other 58% retained normal sensation. The development of SCI-induced neuropathic pain correlated with a marked decrease in the levels of GDNF and artemin in the spinal cord and DRGs. Additionally, a dramatic increase in the density and the distribution throughout the dorsal horn of GFL-responsive afferents was observed in rats with SCI

    Spinal cord injury (SCI) causes dramatic changes in the quality of life, including coping with bladder dysfunction which requires repeated daily and nightly catheterizations. Our laboratory has recently demonstrated in a rat SCI model that repetitive sensory information generated through task-specific stepping and/or loading can improve nonlocomotor functions, including bladder function (Ward PJ, Herrity AN, Smith RR, Willhite A, Harrison BJ, Petruska JC, Harkema SJ, Hubscher CH. J Neurotrauma 31: 819-833, 2014). To target potential underlying mechanisms, the current study included a forelimb-only exercise group to ascertain whether improvements may be attributed to general activity effects that impact target organ-neural interactions or to plasticity of the lumbosacral circuitry that receives convergent somatovisceral inputs. Male Wistar rats received a T9 contusion injury and were randomly assigned to three groups 2 wk postinjury: quadrupedal locomotion, forelimb exercise, or a nontrained group. Throughout the study (including preinjury), all animals were placed in metabolic cages once a week for 24 h to monitor water intake and urine output. Following the 10-wk period of daily 1-h treadmill training, awake cystometry data were collected and bladder and kidney tissue harvested for analysis. Metabolic cage frequency-volume measurements of voiding and cystometry reveal an impact of exercise training on multiple SCI-induced impairments related to various aspects of urinary tract function. Improvements in both the quadrupedal and forelimb-trained groups implicate underlying mechanisms beyond repetitive sensory information from the hindlimbs driving spinal network excitability of the lumbosacral urogenital neural circuitry. Furthermore, the impact of exercise training on the upper urinary tract (kidney) underscores the health benefit of activity-based training on the entire urinary system within the SCI population.

    Spinal arteriovenous malformation (AVM) is a broad term that constitutes diverse vascular pathologies. To date, various classification schemes for spinal AVM have been proposed in literature, which helped neurosurgeons understand the pathophysiology of the disease and determine an optimal treatment strategy. To discuss indications and results of surgical and endovascular interventions for spinal AVM, this article refers to the following classification proposed by Anson and Spetzler in 1992: type I, dural arteriovenous fistula (AVF); type II, glomus intramedullary AVM; type III, juvenile malformations; and type IV, perimedullary AVF. In general, complete obliteration of the fistula is a key for better outcome in type I dural and type IV perimedullary AVFs. On the other hand, in type II glomus and type III juvenile malformations, functional preservation, instead of pursuing angiographical cure, is the main goal of the treatment. In such cases, reduction of the shunt flow can alleviate clinical symptoms. Proper management of spinal AVM should start with neurological examination and understanding of angioarchitectures, which provide critical information that guides the indication and modality of intervention. Finally, close collaboration of the microsurgical and endovascular teams are mandatory for successful treatment. PMID:26948701

    Purpose: Spinal cord ependymomas are rare tumors, accounting for <2% of all primary central nervous system tumors. This study assessed the treatment outcomes for patients diagnosed with spinal cord ependymomas within the Southern California Kaiser Permanente system. Methods and Materials: We studied 23 patients treated with surgery with or without external beam radiotherapy (EBRT). The local and distant control rates and overall survival rates were determined. Results: The overall local control, overall recurrence, and 9-year overall survival rate was 96%, 17.4%, and 63.9%, respectively. Conclusions: The results of our study indicate that en bloc gross total resection should be the initial treatment, with radiotherapy reserved primarily for postoperative cases with unfavorable characteristics such as residual tumor, anaplastic histologic features, or piecemeal resection. Excellent local control and overall survival rates can be achieved using modern microsurgical techniques, with or without local radiotherapy.

    Neurological injury, such as spinal cord injury, has a secondary injury associated with it. The secondary injury results from the biological cascade after the primary injury and affects previous uninjured, healthy tissue. Therefore, the mitigation of such a cascade would benefit patients suffering a primary injury and allow the body to recover more quickly. Unfortunately, the delivery of effective therapeutics is quite limited. Due to the inefficient delivery of therapeutic drugs, nanoparticles have become a major field of exploration for medical applications. Based on their material properties, they can help treat disease by delivering drugs to specific tissues, enhancing detection methods, or a mixture of both. Incorporating nanomedicine into the treatment of neuronal injury and disease would likely push nanomedicine into a new light. This review highlights the various pathological issues involved in secondary spinal cord injury, current treatment options, and the improvements that could be made using a nanomedical approach.

    Cortical reorganization can be induced by exercise below the level of the lesion after spinal cord injury (SCI). The aim of the present study was to investigate the effect of passive and active pedaling exercise on leg motor cortical area excitability of subjects with traumatic SCI. Ten subjects with chronic cervical or thoracic SCI were enrolled in the study. We found a significant effect of pedaling on short-interval intracortical inhibition (SICI), which did not interact with the experimental condition (active vs. passive). This corresponded to a significant reduction of SICI in the subjects with SCI, together with no evidence that this pattern differed for passive vs. active pedaling. We found no significant effect of pedaling on intracortical facilitation. Our results showed that also passive cycling may be beneficial in activating motor cortical regions and possibly also facilitating motor recovery after SCI. The present study confirms and extends the findings of previous studies that have observed task-specific cortical activation during passive pedaling. Therefore passive exercise therapies when applied below the level of the lesion in subjects with SCI could promote cortical neuroplastic reorganization. PMID:27108543

    Abstract Evaluation of locomotor training after spinal cord injury (SCI) has primarily focused on hind limb recovery, with evidence of functional and molecular changes in response to exercise. Since trauma at a cervical (C) level is common in human SCI, we used a unilateral C4 contusion injury model in rats to determine whether forced exercise (Ex) would affect spinal cord biochemistry, anatomy, and recovery of fore and hind limb function. SCI was created with the Infinite Horizon spinal cord impactor device at C4 with a force of 200 Kdyne and a mean displacement of 1600–1800 μm in adult female Sprague-Dawley rats that had been acclimated to a motorized exercise wheel apparatus. Five days post-operatively, the treated group began Ex on the wheel for 20 min per day, 5 days per week for 8 weeks. Wheel speed was increased daily according to the abilities of each animal up to 14 m/min. Control rats were handled daily but were not exposed to Ex. In one set of animals experiencing 5 days of Ex, there was a moderate increase in brain-derived neurotrophic factor (BDNF) and heat shock protein–27 (HSP-27) levels in the lesion epicenter and surrounding tissue. Long-term (8 weeks) survival groups were exposed to weekly behavioral tests to assess qualitative aspects of fore limb and hind limb locomotion (fore limb scale, FLS and BBB [Basso, Beattie, and Bresnahan locomotor rating scale]), as well as sensorimotor (grid) and motor (grip) skills. Biweekly assessment of performance during wheel walking examined gross and fine motor skills. The FLS indicated a significant benefit of Ex during weeks 2–4. The BBB test showed no change with Ex at the end of the 8-week period, however hind limb grid performance was improved during weeks 2–4. Lesion size was not affected by Ex, but the presence of phagocytic and reactive glial cells was reduced with Ex as an intervention. These results suggest that Ex alone can influence the evolution of the injury and transiently

    Background Rapid muscle fatigue during functional electrical stimulation (FES)-evoked muscle contractions in individuals with spinal cord injury (SCI) is a significant limitation to attaining health benefits of FES-exercise. Delaying the onset of muscle fatigue is often cited as an important goal linked to FES clinical efficacy. Although the basic concept of fatigue-resistance has a long history, recent advances in biomedical engineering, physiotherapy and clinical exercise science have achieved improved clinical benefits, especially for reducing muscle fatigue during FES-exercise. This review evaluated the methodological quality of strategies underlying muscle fatigue-resistance that have been used to optimize FES therapeutic approaches. The review also sought to synthesize the effectiveness of these strategies for persons with SCI in order to establish their functional impacts and clinical relevance. Methods Published scientific literature pertaining to the reduction of FES-induced muscle fatigue was identified through searches of the following databases: Science Direct, Medline, IEEE Xplore, SpringerLink, PubMed and Nature, from the earliest returned record until June 2015. Titles and abstracts were screened to obtain 35 studies that met the inclusion criteria for this systematic review. Results Following the evaluation of methodological quality (mean (SD), 50 (6) %) of the reviewed studies using the Downs and Black scale, the largest treatment effects reported to reduce muscle fatigue mainly investigated isometric contractions of limited functional and clinical relevance (n = 28). Some investigations (n = 13) lacked randomisation, while others were characterised by small sample sizes with low statistical power. Nevertheless, the clinical significance of emerging trends to improve fatigue-resistance during FES included (i) optimizing electrode positioning, (ii) fine-tuning of stimulation patterns and other FES parameters, (iii) adjustments to the mode and

    This qualitative study used focus groups to identify meaningful components of exercise and active recreation (E/AR) related to consistent participation for those with spinal cord injury (SCI). Transcripts from each focus group were analyzed with classical content analysis, grounded theory coding, and meaning condensation using the International Classification of Function, Disability and Health (ICF). Variables within each of the ICF domains (body structures and functions, activities/participation, and environment) were indicated as meaningful components leading to increased participation, independence, and reasons why people consistently participated in E/AR. Occupational therapists can utilize these components to implement therapeutic intervisions, which provide clients with a sense of purpose and being, thus improving outcomes in meaningful occupations.

    We asked whether elastic binding of the abdomen influences respiratory mechanics during wheelchair propulsion in athletes with cervical spinal cord injury (SCI). Eight Paralympic wheelchair rugby players with motor-complete SCI (C5-C7) performed submaximal and maximal incremental exercise tests on a treadmill, both with and without abdominal binding. Measurements included pulmonary function, pressure-derived indices of respiratory mechanics, operating lung volumes, tidal flow-volume data, gas exchange, blood lactate, and symptoms. Residual volume and functional residual capacity were reduced with binding (77 ± 18 and 81 ± 11% of unbound, P < 0.05), vital capacity was increased (114 ± 9%, P < 0.05), whereas total lung capacity was relatively well preserved (99 ± 5%). During exercise, binding introduced a passive increase in transdiaphragmatic pressure, due primarily to an increase in gastric pressure. Active pressures during inspiration were similar across conditions. A sudden, sustained rise in operating lung volumes was evident in the unbound condition, and these volumes were shifted downward with binding. Expiratory flow limitation did not occur in any subject and there was substantial reserve to increase flow and volume in both conditions. V̇o2 was elevated with binding during the final stages of exercise (8–12%, P < 0.05), whereas blood lactate concentration was reduced (16–19%, P < 0.05). V̇o2/heart rate slopes were less steep with binding (62 ± 35 vs. 47 ± 24 ml/beat, P < 0.05). Ventilation, symptoms, and work rates were similar across conditions. The results suggest that abdominal binding shifts tidal breathing to lower lung volumes without influencing flow limitation, symptoms, or exercise tolerance. Changes in respiratory mechanics with binding may benefit O2 transport capacity by an improvement in central circulatory function. PMID:24855136

    We asked whether elastic binding of the abdomen influences respiratory mechanics during wheelchair propulsion in athletes with cervical spinal cord injury (SCI). Eight Paralympic wheelchair rugby players with motor-complete SCI (C5-C7) performed submaximal and maximal incremental exercise tests on a treadmill, both with and without abdominal binding. Measurements included pulmonary function, pressure-derived indices of respiratory mechanics, operating lung volumes, tidal flow-volume data, gas exchange, blood lactate, and symptoms. Residual volume and functional residual capacity were reduced with binding (77 ± 18 and 81 ± 11% of unbound, P < 0.05), vital capacity was increased (114 ± 9%, P < 0.05), whereas total lung capacity was relatively well preserved (99 ± 5%).

    Previous studies have shown increased fatigue in paralyzed muscle of spinal cord-injured (SCI) patients (Castro M, Apple D Jr, Hillegass E, and Dudley GA. Eur J Appl Physiol 80: 373-378, 1999; Gerrits H, Hopman MTE, Sargeant A, and de Haan A. Clin Physiol 21: 105-113, 2001). Our purpose was to determine whether the increased muscle fatigue could be due to a delayed rise in blood flow at the onset of exercise in SCI individuals. Isometric electrical stimulation was used to induce fatigue in the quadriceps femoris muscle of seven male, chronic (>1 yr postinjury), complete (American Spinal Injury Association, category A) SCI subjects. Cuff occlusion was used to elevate blood flow before electrical stimulation, and the magnitude of fatigue was compared with a control condition of electrical stimulation without prior cuff occlusion. Blood flow was measured in the femoral artery by Doppler ultrasound. Prior cuff occlusion increased blood flow in the first 30 s of stimulation compared with the No-Cuff condition (1,350 vs. 680 ml/min, respectively; P < 0.001), although blood flow at the end of stimulation was the same between conditions (1,260 +/- 140 vs. 1,160 +/- 370 ml/min, Cuff and No-Cuff condition, respectively; P = 0.511). Muscle fatigue was not significantly different between prior cuff occlusion and the control condition (32 +/- 13 vs. 35 +/- 10%; P = 0.670). In conclusion, increased muscle fatigue in SCI individuals is not associated with the prolonged time for blood flow to increase at the onset of exercise. PMID:14506095

    The application of electrical current to injured tissue is known to promote healing. The use of this modality in healing the injured spinal cord to promote neurologic recovery has been introduced as a potential treatment for patients who previously had minimal hope of recovery. In in vitro and in vivo experiments, neural regeneration has been seen to occur, especially when an oscillating field is used. With this modality, an electrical current is applied in which the polarity changes direction on a periodic basis, preventing the "die-back" phenomenon of severed neural pathways. This mechanism of recovery has been demonstrated in several species in which sacrifice has been undertaken and spinal cords examined. In a study of humans, a small number of patients participated in a single phase Ia trial in which the safety of an implantable device was demonstrated, with indications of probable benefit, consistent with laboratory and animal studies. In addition, a number of additional patients were treated, and their results were examined along with the original cohort and were compared with historical control subjects. The device used in this mode of treatment has not been approved for use in the general spinal cord-injured population, pending further study. A larger multi-institutional trial needs to be done to further demonstrate efficacy and effectiveness, and outcomes will need to be agreed upon by spinal cord injury researchers, patients, and regulators before widespread use will be permitted. Unfortunately, some subtle changes experienced and valued by patients are not recognized as important or desirable by regulators or by all researchers. PMID:21172690

    This study investigated the effects of acute hypoxia on spinal reflexes and soleus muscle function after a sustained contraction of the plantar flexors at 40% of maximal voluntary isometric contraction (MVC). Fifteen males (age 25.3 ± 0.9 year) performed the fatigue task at two different inspired O₂ fractions (FiO₂ = 0.21/0.11) in a randomized and single-blind fashion. Before, at task failure and after 6, 12 and 18 min of passive recovery, the Hoffman-reflex (H max) and M-wave (M max) were recorded at rest and voluntary activation (VA), surface electromyogram (RMSmax), M-wave (M sup) and V-wave (V sup) were recorded during MVC. Normalized H-reflex (H max/M max) was significantly depressed pre-exercise in hypoxia compared with normoxia (0.31 ± 0.08 and 0.36 ± 0.08, respectively, P < 0.05). Hypoxia did not affect time to task failure (mean time of 453.9 ± 32.0 s) and MVC decrease at task failure (-18% in normoxia vs. -16% in hypoxia). At task failure, VA (-8%), RMSmax/M sup (-11%), H max/M max (-27%) and V sup/M sup (-37%) decreased (P < 0.05), but with no FiO2 effect. H max/M max restored significantly throughout recovery in hypoxia but not in normoxia, while V sup/M sup restored significantly during recovery in normoxia but not in hypoxia (P < 0.05). Collectively, these findings indicate that central adaptations resulting from sustained submaximal fatiguing contraction were not different in hypoxia and normoxia at task failure. However, the FiO₂-induced differences in spinal loop properties pre-exercise and throughout recovery suggest possible specific mediation by the hypoxic-sensitive group III and IV muscle afferents, supraspinal regulation mechanisms being mainly involved in hypoxia while spinal ones may be predominant in normoxia.

    Pain is a common consequence of a spinal cord injury (SCI) and has a major impact on quality of life through its impact on physical function, mood and participation in work, recreational and social activities. Several types of pain typically present following SCI with central neuropathic pain being a frequent and difficult to manage occurrence. Despite advances in our understanding of the mechanisms contributing to this type of pain and an increasing number of trials examining treatment efficacy, our ability to relieve neuropathic SCI pain is still very limited. Optimal management relies upon an integrated approach that uses a combination of pharmacological and nonpharmacological options. PMID:26402151

    Duchenne muscular dystrophy is a progressive disease with loss of ambulation at around 9-10 years of age, followed, if untreated, by development of scoliosis, respiratory insufficiency, and death in the second decade of life. This review highlights the natural history of the disease, in particular, with regard to the development of the spinal deformity and how this complication has been modified by surgical interventions and overall by corticosteroid treatment. The beneficial effect of corticosteroids may have also an impact on the clinical trial design of the new emerging causative therapies.

    Spinal pathology resulting in cerebrospinal fluid (CSF) leak and intracranial hypotension is an infrequently reported and a potentially severe cause of headaches. We present a case of cerebrospinal fluid (CSF) leak caused by a thoracic disk herniation successfully treated with two targeted epidural blood patches. Although patients typically present with orthostatic headaches, the imaging findings of intracranial hypotension should prompt investigation of the spine for site and cause of the CSF leakage. Treatment includes autologous blood patch and surgery in refractory cases. PMID:26914140

    Background While enhancing physical activity has been an essential goal of public health officials, people with physical impairments such as spinal cord injury (SCI) are more likely to live a sedentary lifestyle. Exercise has been shown to decrease the risk for many of the secondary conditions associated with SCI, including osteoporosis, cardiovascular disease, pressure ulcers, urinary tract infections, diabetes and arthritis, yet this population is rarely a target for health promotion efforts. This paper examines the self-reported exercise experiences of people with SCI using a qualitative-exploratory design. Methods We enrolled 26 individuals with SCI (15 self-described 'exercisers' and 11 'non-exercisers') from a non-random pool of survey responders. Semi-structured phone interviews were conducted to record participants' experiences with exercise pre/post injury, barriers and facilitators to being active and perceived health impact. Results Regardless of exercise status, all participants reported physical activity prior to injury and expressed interest in becoming active or maintaining an active lifestyle. Participants identified a range of both motivational and socio-environmental factors that were either facilitating or constraining of such a lifestyle. Non-exercisers identified barriers to exercise, including a perceived low return on physical investment, lack of accessible facilities, unaffordable equipment, no personal assistance and fear of injury. Exercisers identified facilitators, including personal motivation, independence, availability of accessible facilities and personal assistants, fear of health complications, and weight management. Exercisers associated a greater range of specific health benefits with being active than non-exercisers. Conclusion Despite motivation and interest in being exercise active, people with SCI face many obstacles. Removal of barriers coupled with promotion of facilitating factors, is vital for enhancing opportunities for

    Exercise and sports activity are beneficial both physically and psychologically but excessive exercise may have adverse physiological and psychological effects. There are methodological issues in the definition, diagnosis and etiology of exercise addiction. Several questionnaires and diagnostic tools have been developed and validated and they show high validity and reliability. Exercise addiction has been suggested as having an obsessive-compulsive dimension as well as rewarding aspects that may include it among the behavioral addictions. Biological studies show that in rodents, exercise such as wheel running activates the dopamine reward system and thus contributing to stress reduction. Further evidence suggests that running is associated with endorphins and cannabinoids thus explaining the "runners high" or euphoric feelings that may lead to exercise addiction. Genetic studies suggest that genes which control preference for drugs also control the preference for naturally rewarding behaviors such as exercise. Psychological studies also explain exercise addiction in terms of reward, habituation, social support, stress-relief, avoidance of withdrawal and reduction of anxiety. It has been suggested that exercise addiction is a part of a continuum of sportive activity that develops in stages from the recreational exercise to at-risk exercise, problematic exercise and finally into exercise addiction. Assessment and treatment should take into account the various stages of exercise addiction development, its comorbidity with other psychiatric disorders such as eating disorders or substance use and alcohol disorders. Treatment approaches for exercise addiction are based on the cognitive-behavioral approach but little is known about their effectiveness. A single-case study shows promise of pharmacological treatment for exercise addiction and further studies are required. This review summarizes diagnostic and phenomenology of exercise addiction with emphasis on

  1. Comparison of non-surgical treatment methods for patients with lumbar spinal stenosis: protocol for a randomized controlled trial

    2014-01-01

    Background Lumbar spinal stenosis is the most common reason for spinal surgery in older adults. Previous studies have shown that surgery is effective for severe cases of stenosis, but many patients with mild to moderate symptoms are not surgical candidates. These patients and their providers are seeking effective non-surgical treatment methods to manage their symptoms; yet there is a paucity of comparative effectiveness research in this area. This knowledge gap has hindered the development of clinical practice guidelines for non-surgical treatment approaches for lumbar spinal stenosis. Methods/design This study is a prospective randomized controlled clinical trial that will be conducted from November 2013 through October 2016. The sample will consist of 180 older adults (>60 years) who have both an anatomic diagnosis of stenosis confirmed by diagnostic imaging, and signs/symptoms consistent with a clinical diagnosis of lumbar spinal stenosis confirmed by clinical examination. Eligible subjects will be randomized into one of three pragmatic treatment groups: 1) usual medical care; 2) individualized manual therapy and rehabilitative exercise; or 3) community-based group exercise. All subjects will be treated for a 6-week course of care. The primary subjective outcome is the Swiss Spinal Stenosis Questionnaire, a self-reported measure of pain/function. The primary objective outcome is the Self-Paced Walking Test, a measure of walking capacity. The secondary objective outcome will be a measurement of physical activity during activities of daily living, using the SenseWear Armband, a portable device to be worn on the upper arm for one week. The primary analysis will use linear mixed models to compare the main effects of each treatment group on the changes in each outcome measure. Secondary analyses will include a responder analysis by group and an exploratory analysis of potential baseline predictors of treatment outcome. Discussion Our study should provide evidence

    Sweat production is crucial for thermoregulation. However, sweating can be problematic for individuals with spinal cord injuries (SCI), as they display a blunting of sudomotor and vasomotor responses below the level of the injury. Sweat gland density and eccrine gland metabolism in SCI are not well understood. Consequently, this study examined sweat lactate (S-LA) (reflective of sweat gland metabolism), active sweat gland density (SGD), and sweat output per gland (S/G) in 7 SCI athletes and 8 able-bodied (AB) controls matched for arm ergometry VO2peak. A sweat collection device was positioned on the upper scapular and medial calf of each subject just prior to the beginning of the trial, with iodine sweat gland density patches positioned on the upper scapular and medial calf. Participants were tested on a ramp protocol (7 min per stage, 20 W increase per stage) in a common exercise environment (21±1°C, 45-65% relative humidity). An independent t-test revealed lower (p<0.05) SGD (upper scapular) for SCI (22.3 ±14.8 glands · cm−2) vs. AB. (41.0 ± 8.1 glands · cm−2). However, there was no significant difference for S/G between groups. S-LA was significantly greater (p<0.05) during the second exercise stage for SCI (11.5±10.9 mmol · l−1) vs. AB (26.8±11.07 mmol · l−1). These findings suggest that SCI athletes had less active sweat glands compared to the AB group, but the sweat response was similar (SLA, S/G) between AB and SCI athletes. The results suggest similar interglandular metabolic activity irrespective of overall sweat rate. PMID:26424929

    Presurgical devascularization of hypervascular spinal metastases has been shown to be effective in preventing major blood loss during open surgery. Most often, embolization can be performed using polyvinyl alcohol (PVA) microparticles. However, in some cases, the close relationship between the feeders of the metastases and the feeders of the anterior spinal artery (ASA) poses a risk of spinal cord ischemia when PVA microparticle embolization is performed. The authors present their early experience in the treatment of spinal metastases close to the ASA; in 2 cases they injected Onyx-18, by direct puncture, into hypervascular posterior arch spinal metastases situated close to the ASA. Two women, one 36 and the other 55 years of age, who presented with spinal lesions (at the posterior arch of C-4 and T-6, respectively) from thyroid and a kidney tumors, were sent to the authors' department to undergo presurgical embolization. After having performed a complete spinal digital subtraction angiography study, a regular angiography catheter was positioned at the ostium of the artery that mainly supplied the lesion. Then, with the patient in the left lateral decubitus position, direct puncture with 18-gauge needles of the lesion was performed using roadmap guidance. Onyx-18 was injected through the needles under biplanar fluoroscopy. Satisfactory devascularization of the lesions was obtained; the ASA remained patent in both cases. The metastases were surgically removed in both cases within the 48 hours after the embolization and major blood loss did not occur. Presurgical devascularization of hypervascular spinal metastases close the ASA by direct puncture with Onyx-18 seems to be an effective technique and appears to be safe in terms of the preserving the ASA's patency.

    Background Exercise has been shown to reduce symptoms of anxiety, but few studies have studied exercise in individuals pre-selected because of their high anxiety. Purpose To review and critically evaluate studies of exercise training in adults with either high levels of anxiety or an anxiety disorder. Methods We conducted a systematic review of randomized clinical trials (RCTs) in which anxious adults were randomized to an exercise or non-exercise control condition. Data were extracted concerning anxiety outcomes and study design. Existing meta-analyses were also reviewed. Results Evidence from 12 RCTs suggested benefits of exercise, for select groups, similar to established treatments and greater than placebo. However, most studies had significant methodological limitations, including small sample sizes, concurrent therapies, and inadequate assessment of adherence and fitness levels. Conclusions Exercise may be a useful treatment for anxiety, but lack of data from rigorous, methodologically sound RCTs precludes any definitive conclusions about its effectiveness. PMID:25697132

    Spinal dural arteriovenous fistulas (DAVFs) are the most commonly encountered vascular malformation of the spinal cord and a treatable cause of progressive para- or tetraplegia. It is an elusive pathology that tends to be under-diagnosed, due to lack of awareness among clinicians, and affects males more commonly than females, typically between the fifth and eighth decades. Early diagnosis and treatment may significantly improve outcome and prevent permanent disability and even mortality. The purpose of our retrospective, single-center study was to determine the long-term clinical and radiographic outcome of patients who have received endovascular or surgical treatment of a spinal DAVF. In particular, during a 6-year period (2009–2014) 14 patients with a spinal DAVF were treated at our department either surgically (n = 4) or endovascularly (n = 10) with detachable coils and/or glue. There was no recurrence in the follow-up period (mean: 36 months, range 3–60 months) after complete occlusion with the endovascular treatment (n = 9; 90%), while only one patient (10%) had residual flow both post-treatment and at 3-month follow-up. All four surgically treated patients (100%) had no signs of residual DAVF on follow-up magnetic resonance angiography (MRA) and/or angiography (mean follow-up period of 9 months). Since improvement or stabilization of symptoms may be seen even in patients with delayed diagnosis and substantial neurological deficits, either endovascular or surgical treatment is always justified.

    Update on pathologies of adult spinal deformity (ASD): With advancement of aging society, ASD has become one of the most notable topics of spinal disorders owing to its significant impact on health related quality of life. Treatment for ASD is challenging due to complex nature of deformity and high prevalence of comorbidities. Spino-pelvic harmony that is evaluated by pelvic incidence (PI) minus lumbar lordosis (LL) is the most important concept, which allows us to understand pathology of ASD more deeply. Proposed optimum "PI minus LL" is within ±10°. However, according to analysis of patients having good surgical outcomes, minimum requirement of postoperative "PI minus LL" is calculated by following equation: "PI minus LL" = 0.41PI - 11.12 (r = 0.45, p = 0.0059). "PI minus LL" is not fixed but flexible value reflecting the specific setting of the individual PI. To date, little is known about dynamic global sagittal alignment that is susceptible to compensatory mechanisms. Gait analysis revealed that compensated sagittal balance by pelvic retroversion in static standing was lost immediately after walking due to alignment change of the pelvis and worsened over time. Dynamic assessment of sagittal balance is recommended. Update on surgical strategies for ASD: We classified ASD into following 5 types in terms of curve patterns, global balance, and curve flexibility: Type 1, well-balanced scoliosis with flexible kyphosis is indicated for corrective posterior spinal fusion (PSF) without any release procedures; Type 2, poor-balanced scoliosis with flexible kyphosis is well corrected by aggressive intervertebral release with PSF; Type 3, fixed sagittal imbalance without coronal deformity is candidate for pedicle subtraction osteotomy; Type 4, fixed sagittal imbalance with coronal deformity is indicated for vertebral column resection; and Type 5, severe scoliosis without marked global sagittal malalignment can be treated by corrective anterior spinal fusion

    Neuropathic pain is a debilitating consequence of spinal cord injury (SCI) that correlates with sensory fiber sprouting. Recent data indicate that exercise initiated early after SCI prevents the development of allodynia and modulated nociceptive afferent plasticity. This study determined if delaying exercise intervention until pain is detected would similarly ameliorate established SCI-induced pain. Adult, female Sprague-Dawley rats with a C5 unilateral contusion were separated into SCI allodynic and SCI non-allodynic cohorts at 14 or 28 days postinjury when half of each group began exercising on automated running wheels. Allodynia, assessed by von Frey testing, was not ameliorated by exercise. Furthermore, rats that began exercise with no allodynia developed paw hypersensitivity within 2 weeks. At the initiation of exercise, the SCI Allodynia group displayed marked overlap of peptidergic and non-peptidergic nociceptive afferents in the C7 and L5 dorsal horn, while the SCI No Allodynia group had scant overlap. At the end of 5 weeks of exercise both the SCI Allodynia and SCI No Allodynia groups had extensive overlap of the 2 c-fiber types. Our findings show that exercise therapy initiated at early stages of allodynia is ineffective at attenuating neuropathic pain, but rather that it induces allodynia-aberrant afferent plasticity in previously pain-free rats. These data, combined with our previous results, suggest that there is a critical therapeutic window when exercise therapy may be effective at treating SCI-induced allodynia and that there are postinjury periods when exercise can be deleterious.

    Traditional palliative treatment of metastatic cancer to the vertebral bodies often results in doses to the spinal cord that are higher than the dose prescribed to the target, or gross tumor volume (GTV). This study compares traditional techniques of spine palliation with intensity-modulated radiation therapy (IMRT). The purpose of the study is 2-fold: first, the study demonstrates the benefits of using IMRT to lower the dose to the organs at risk (OAR), particularly for the spinal cord and other nonspecified normal tissues; second, the article provides information regarding the advantages and disadvantages of commonly used conventional techniques for treating the vertebral bodies based on patient anatomy. Because the use of IMRT or other advanced techniques may be prohibitive because of insurance issues, treatment plans were created that compared optimal coverage vs. optimal sparing for single-field, wedged-pair, and opposed-beam arrangements. Fifty-five patients were selected and divided by location of target (cervical, thoracic, and lumbar spine) and also by the measured separation between the anterior and posterior surface of the patient at the level of mid-GTV. Within each anatomic category the patients again were divided into the categories of small, medium, and large based on separation. The patient dataset that most closely represented the average separation within each category was selected, resulting in a total of 9 patients, and the appropriate treatment plan techniques were calculated for each of the 9 patients. The results of the study do show that the use of IMRT is far superior when compared with other techniques, both for coverage and for sparing of the surrounding tissue, regardless of patient size and the section of spine being treated. Based on a combination of both target coverage and sparing of normal tissues, the conventional plan of choice may vary by both the section of spine to be treated and by the size of the patient.

    Neuroimaging studies for persons in the National Collaborative Chicago-Based Congenital Toxoplasmosis Study (NCCCTS) with symptoms and signs referable to the spinal cord were reviewed. Three infants had symptomatic spinal cord lesions, another infant a Chiari malformation, and another infant a symptomatic peri-spinal cord lipoma. One patient had an unusual history of prolonged spinal cord symptoms presenting in middle age. Neuroimaging was used to establish her diagnosis and response to treatment. This 43 year-old woman with congenital toxoplasmosis developed progressive leg spasticity, weakness, numbness, difficulty walking, and decreased visual acuity and color vision without documented re-activation of her chorioretinal disease. At 52 years of age, spinal cord lesions in locations correlating with her symptoms and optic atrophy were diagnosed with 3 Tesla MRI scan. Treatment with pyrimethamine and sulfadiazine decreased her neurologic symptoms, improved her neurologic examination, and resolved her enhancing spinal cord lesions seen on MRI. PMID:23487348

    Spinal Traumas have been categorized as disabling diseases that cause irretrievable personal and social problems. Having conducted a rather comprehensive diagnosis of the anatomy of the backbone and spinal cord as well as their functions, Avicenna (Ibn Sina, 980-1037) stated the levels and kinds of spinal impairments that are caused by spinal traumas in his great masterpiece Al-Qanun fi al-Tibb (The Canon of Medicine). He also based his treatment process on his etiological diagnosis of such impairments. Avicenna had used the following methods to treat spinal traumas: food and drug therapy and regimental therapies such as massage, phlebotomy, cupping, dry sauna, and surgery. The authors of the present article review the bases of Avicenna's viewpoints regarding spinal traumas and their treatment. PMID:25772611

    The authors report their experiences based on 41 cases operated on for lumbar spinal stenosis between 1981 and 1988. The series included 28 men and 13 women aged between 23 and 63 years (mean age: 48 years). Neurogenic intermittent claudication was the presenting symptom in only 12% of the cases, as opposed to lumbago-sciatica in 78%. Clinical examination did not provide any specific elements. The key to diagnosis was lumbar myelography. Laminectomy was the most important aspect of treatment which, in certain cases, was associated with vertebral stabilization by arthrodesis (3 cases). There were ten minor operative complications. Further surgery was necessary in five cases (12%). Therapeutic results in patients followed from one to eight years (35 cases) were satisfactory. The discussion covers nosologic, clinicoradiologic and therapeutic aspects. PMID:2142258

    The bones are the most common location for metastases, which may cause severe pain and damage, including osteolytic destruction and fractures. Pathological fractures of the spine are extremely painful and cause significant disability and morbidity in patients. Traditional open surgery has numerous complications, and radiation therapy may take weeks to become effective. To avoid the trauma and complication of open surgery, percutaneous kyphoplasty (PKP) is a minimally invasive procedure that has played a great role in the treatment of spinal metastases over the past several years. To evaluate the efficacy and safety of the treatment of spinal metastasis using PKP, the present study evaluated 282 patients who had received PKP between April 2009 and June 2014. The efficacy of PKP was evaluated using the visual analog scale for pain (VAS), Karnofsky performance score (KPS) and quality of life (QOL) score (short form with 36 questions). The KPS and QOL were measured pre-operatively and 3 months post-operatively. In addition, radiographical data, including the degree of restoration of the kyphotic angle and the anterior vertebral height, and leakage of bone cement, were measured. The safety of the surgery was assessed by complications and side effects reported during or subsequent to surgery. The present study measured the parameters prior to the surgery and at 24 h, 3 months, 6 months and 1 year post-surgery, as well as at the last follow-up date. The range of the follow-up time was between 105 days and 15 months (mean, 401 days). The 282 patients underwent successful operations and the pain felt by the patients prior to the surgery was significantly alleviated. In addition, the analgesic intake of patients greatly decreased following PKP. KPS improved prior to and 3 months after the surgery. QOL also improved prior to and 3 months after the surgery. Radiographical data demonstrated that the kyphotic angle decreased following PKP, and the anterior vertebral height

    The purpose of this study was to determine the validity of the 6-min arm ergometry test (6MAT) in predicting peak oxygen consumption (V̇O2peak) in individuals with chronic spinal cord injury (SCI). Fifty-two individuals with chronic SCI (age, 38 ± 10 years; American Spinal Injury Association Impairment Scale (AIS), A-D; neurological level of injury (NLI), C1-L2; years post-injury (YPI), 13 ± 10 years) completed an incremental arm ergometry V̇O2peak test and a submaximal 6MAT. Oxygen consumption (V̇O2) data from both tests were used to create a predictive equation with regression analysis. Subsequently, a cross-validation group comprising an additional 10 individuals with SCI (age, 39 ± 13 years; AIS, A-D; NLI, C3-L3; YPI, 9 ± 9 years) were used to determine the predictive power of the equation. All participants were able to complete both the V̇O2peak and 6MAT assessments. Regression analysis yielded the following equation to predict V̇O2peak from end-stage 6MAT V̇O2: V̇O2peak (mL·kg(-1)·min(-1)) = 1.501(6MAT V̇O2) - 0.940. Correlation between measured and predicted V̇O2peak was excellent (r = 0.89). No significant difference was found between measured (17.41 ± 7.44 mL·kg(-1)·min(-1)) and predicted (17.42 ± 6.61 mL·kg(-1)·min(-1)) V̇O2peak (p = 0.97). When cross-validated with a sample of 10 individuals with SCI, correlation between measured and predicted V̇O2peak remained high (r = 0.89), with no differences between measured (18.81 ± 8.35 mL·kg(-1)·min(-1)) and predicted (18.73 ± 7.27 mL·kg(-1)·min(-1)) V̇O2peak (p = 0.75). Results suggest that 6MAT V̇O2 can be used to predict V̇O2peak among individuals with chronic SCI. The 6MAT should be used as a clinical tool for assessing aerobic capacity when peak exercise testing is not feasible. PMID:27363732

    Long-term functional impairments due to spinal cord injury (SCI) in the rat result from secondary apoptotic death regulated, in part, by SCI-induced decreases in protein levels of the antiapoptotic protein Bcl-xL. We have shown that exogenous administration of Bcl-xL spares neurons 24 h after SCI. However, long-term effects of chronic application of Bcl-xL have not been characterized. To counteract SCI-induced decreases in Bcl-xL and resulting apoptosis, we used the TAT protein transduction domain fused to the Bcl-xL protein (Tat-Bcl-xL), or its antiapoptotic domain BH4 (Tat-BH4). We used intrathecal delivery of Tat-Bcl-xL, or Tat-BH4, into injured spinal cords for 24 h or 7 days, and apoptosis, neuronal death and locomotor recovery were assessed up to 2 months after injury. Both, Tat-Bcl-xL and Tat-BH4, significantly decreased SCI-induced apoptosis in thoracic segments containing the site of injury (T10) at 24 h or 7 days after SCI. However, the 7-day delivery of Tat-Bcl-xL, or Tat-BH4, also induced a significant impairment of locomotor recovery that lasted beyond the drug delivery time. We found that the 7-day administration of Tat-Bcl-xL, or Tat-BH4, significantly increased non-apoptotic neuronal loss and robustly augmented microglia/macrophage activation. These results indicate that the antiapoptotic treatment targeting Bcl-xL shifts neuronal apoptosis to necrosis, increases the inflammatory response and impairs locomotor recovery. Our results suggest that a combinatorial treatment consisting of antiapoptotic and anti-inflammatory agents may be necessary to achieve tissue preservation and significant improvement in functional recovery after SCI.

    Previous findings suggest that exercise is a safe and efficacious means of improving physiological and psychosocial outcomes in female breast cancer survivors. To date, most research has focused on post-treatment interventions. However, given that the type and severity of treatment-related adverse effects may be dependent on the type of treatment, and that the effects are substantially more pronounced during treatment, an assessment of the safety and efficacy of exercise during treatment is warranted. In this review, we present and evaluate the results of randomized controlled trials (RCTs) conducted during breast cancer treatment. We conducted literature searches to identify studies examining exercise interventions in breast cancer patients who were undergoing chemotherapy or radiation. Data were extracted on physiological and psychosocial outcomes. Cohen's d effect sizes were calculated for each outcome. A total of 17 studies involving 1,175 participants undergoing active cancer therapy met the inclusion criteria. Findings revealed that, on average, exercise interventions resulted in moderate to large improvements in muscular strength: resistance exercise (RE, = 0.86), aerobic exercise (AE, = 0.55), small to moderate improvements in cardiovascular functioning (RE, = 0.45; AE, = 0.17, combination exercise (COMB, = 0.31) and quality of life (QoL; RE, = 0.30; AE, = 0.50; COMB, = 0.63). The results of this review suggest that exercise is a safe, feasible, and efficacious intervention in breast cancer patients who are undergoing different types of treatment. Additional research addressing the different modes of exercise during each type of treatment is warranted to assess the comparable efficacy of the various exercise modes during established breast cancer treatments.

    Spinal cord stimulation (SCS) is a well known method of treatment used worldwide since the 80's of the last century. High efficiency of SCS was observed in the treatment of various types of pain. Promising clinical results were observed in the treatment of patients with refractory angina (RA). Reduction of angina attacks reduces doses of medications and improves quality of life. SCS efficacy in RA is comparable to that observed among patients treated with cardiac surgery (CABG) and percutaneous coronary intervention (PCI), with lower risk of complications and rehospitalisation. SCS is more cost effective compared to CABG and PCI. SCS might be considered for patients who did not respond to reperfusion therapy. The mechanism of action in RA is not well understood. It is known that SCS reduces the activity of the sympathetic nervous system, by which improves the coronary perfusion and oxygenation of the heart muscle. It is important that SCS does not mask the pain related to the infarct. PMID:21523677

    Current treatment for spinal cord injury (SCI) is supportive at best; despite great efforts, the lack of better treatment solutions looms large on neurological science and medicine. Curcumin, the active ingredient in turmeric, a spice known for its medicinal and anti-inflammatory properties, has been validated to harbor immense effects for a multitude of inflammatory-based diseases. However, to date there has not been a review on curcumin's effects on SCI. Herein, we systematically review all known data on this topic and juxtapose results of curcumin with standard therapies such as corticosteroids. Because all studies that compare the two show superior results for curcumin over corticosteroids, it could be true that curcumin better acts at the inflammatory source of SCI-mediated neurological injury, although this question remains unanswered in patients. Because curcumin has shown improvements from current standards of care in other diseases with few true treatment options (e.g., osteoarthritis), there is immense potential for this compound in treating SCI. We critically and systematically summarize available data, discuss clinical implications, and propose further testing of this well-tolerated compound in both the preclinical and the clinical realms. Analyzing preclinical data from a clinical perspective, we hope to create awareness of the incredible potential that curcumin shows for SCI in a patient population that direly needs improvements on current therapy.

    A retrospective review of thirty-eight patients (16 males and 22 females) with spinal infection between 1993 and 1998 revealed that the mean age was 39.9 years and the peak incidence was in the 5th decade of life. Infections in thirty-two patients (84.2%) were tuberculous in origin, 13.2% were pyogenic and 2.6% were fungal. Back pain was a symptom in 94.7% while 55.8% had neurological deficits, of which two-thirds were tuberculous in origin. Twenty-two patients (57.9%) had an impaired immune status secondary to pulmonary either tuberculosis, diabetes mellitus, intravenous drug abuse, prolonged steroid treatment, malnutrition, or advanced age. History of contact with tuberculous patients was elicited in 31.3%, extraskeletal tuberculosis was found in 28.1%, while Mantoux test was only positive in 53.1% of tuberculous patients. Majority of the cases (57.9%) involved lumbar vertebra. The histopathological examination was only positive in 22.2% from material taken via CT guided biopsy but 93.3% were found to be conclusive from open biopsy. 4 out of 5 patients who had a pyogenic infection were treated conservatively and produced a good result. There was no difference in outcome for tuberculosis patients treated with either the 3 drug or 4 drug regimen. Anterior decompression and bone grafting in tuberculous patients was superior in terms of a faster fusion rate, early pain relief and prevention of kvphotic deformity. The initial neurological deficit did not reflect the future prognosis of patients with spinal infection. PMID:11200039

    China ranks second among the 22 countries with the highest burden of tuberculosis. The goals of this study were to evaluate the clinical outcomes of treatment of skipped multisegmental spinal tuberculosis and to investigate the selection strategy for the optimal procedure based on focal characteristics. From March 1999 to December 2013, 24 patients with skipped multisegmental spinal tuberculosis were enrolled in this study. Ten patients underwent an anterior procedure (anterior group). Four patients underwent a combined anterior and posterior procedure (combined anterior and posterior group). Ten patients underwent a posterior procedure (posterior group). All patients were evaluated according to clinical presentation and radiographic, computed tomography, and magnetic resonance imaging findings. The focal tissues of all patients underwent drug susceptibility testing. The patients underwent clinical and radiologic follow-up an average of 18.6 months post-operatively. The cohort included 13 male and 11 female patients (age range, 15-69 years). The patients showed significant improvement in deformity and neurologic deficits. All patients had graft union 6 to 12 months postoperatively. No patient had surgical complications. Postoperative recurrence occurred in 1 patient in the combined anterior and posterior group. Two patients had strains that were resistant to at least 1 anti-tuberculosis drug. One patient had multidrug-resistant strains. All 24 patients had achieved cure at final follow-up. This study showed that the 3 procedures can safely and effectively achieve nerve decompression, graft fusion, and kyphosis correction. The procedure should be chosen according to the patient's general condition, focal characteristics, and type of complication, and the surgeon's experience. PMID:26709565

    Objective: The purpose of this pilot study was to investigate the effectiveness of a mixed-reality (MR) exercise environment on engagement and enjoyment levels of individuals with spinal cord injury (SCI) and intellectual and developmental disabilities (IDD). Methods: Six people participated in this cross-sectional, observational pilot study involving one MR exercise trial. The augmented reality environment was based on a first-person perspective video of a scenic biking/walking trail in Colorado. Males and females (mean age, 43.3 ± 13.7 years) were recruited from a research database for their participation in previous clinical studies. Of the 6 participants, 2 had SCI, 2 had IDD, and 2 were without disability. The primary outcome measurement of this pilot study was the self-reported engagement and enjoyment level of each participant after the exercise trial. Results: All participants reported increased levels of engagement, enjoyment, and immersion involving the MR exercise environment as well as positive feedback recommending this type of exercise approach to peers with similar disabilities. All the participants reported higher than normal levels of enjoyment and 66.7% reported higher than normal levels of being on a real trail. Conclusion: Participants’ feedback suggested that the MR environment could be entertaining, motivating, and engaging for users with disabilities, resulting in a foundation for further development of this technology for use in individuals with cognitive and physical disabilities.

    Most men with spinal cord injury (SCI) are infertile. Erectile dysfunction, ejaculatory dysfunction and semen abnormalities contribute to the problem. Treatments for erectile dysfunction include phosphodiesterase type 5 inhibitors, intracavernous injections of alprostadil, penile prostheses, and vacuum constriction devices. In anejaculatory patients who wish to father children, semen retrieval is necessary. Penile vibratory stimulation is recommended as the first line of treatment. Patients who fail penile vibratory stimulation can be referred for electroejaculation. If this approach is not possible, prostate massage is an alternative. Surgical sperm retrieval should be considered as a last resort when other methods fail. Most men with SCI have a unique semen profile characterized by normal sperm count but abnormally low sperm motility. Scientific investigations indicate that accessory gland dysfunction and abnormal semen constituents contribute to the problem. Despite abnormalities, sperm from men with SCI can successfully induce pregnancy. In selected couples, the simple method of intravaginal insemination is a viable option. Another option is intrauterine insemination. The efficacy of intrauterine insemination increases as the total motile sperm count inseminated increases. In vitro fertilization and intracytoplasmic sperm injection are options in cases of extremely low total motile sperm count. Reproductive outcomes for SCI male factor infertility are similar to outcomes for general male factor infertility. PMID:20157304

    2012-01-01

    Spinal cord injury (SCI) occurs most often to young men. Following SCI, most men are infertile due to a combination of erectile dysfunction, ejaculatory dysfunction and semen abnormalities. Erectile dysfunction may be treated by the same therapies that are used in the general population. Similarly, the same treatments that are effective to assist conception in couples with non-SCI male factor patients are effective in assisting conception in SCI male-factor patients. The most apparent differences in male-factor symptoms between SCI and non-SCI patients are the high occurrences of anejaculation and atypical semen profiles in men with SCI. Methods available to assist ejaculation in men with SCI include penile vibratory stimulation and EEJ. Use of surgical sperm retrieval as the first line of treatment for anejaculation in men with SCI is controversial. Most men with SCI have a unique semen profile characterized by normal sperm concentration, but abnormally low sperm motility. Toxic substances in the semen contribute to this problem. Despite impaired sperm parameters, pregnancy outcomes using sperm from men with SCI are similar to pregnancy outcomes using sperm from non-SCI men. Future studies should focus on improving natural ejaculation and improving semen quality in these men. PMID:24278717

    Certain types of cancer pain fail to respond well either to systemic drug therapy or to spinal opioids because of the occurrence of intolerable adverse effects. In addition to spinal opioids other drugs may produce an antinociceptive effect when administered by the spinal route, such as local anesthetics, NSAID, alpha 2-agonists, calcium-channel blockers, NMDA antagonists, cholinergic drugs, peptides such as somatostatin, octreotide or calcitonin, adenosine agonists, benzodiazepines, neurokinin and cholecystokinin antagonists, nitric oxide synthase inhibitors, corticosteroids, and enkephalinase inhibitors. All these drugs may be administered in combination between them, realising the so called balanced spinal analgesia. The aim of this study is to analyse: the available methods for the evaluation of pharmacological interactions, the types of interaction between different spinal antinociceptive drugs and the role of balanced spinal analgesia in the treatment of cancer pain. Analysis of the presented data shows that the spinal synergism between opioids-local anesthetics and opioids-alpha 2-agonists can be useful in the treatment of opioid refractory cancer pain. Furthermore, the use of cholinergic drugs combined with opioids and alpha 2-agonists may be promising. Finally, even if the synergism between NSAID or NMDA antagonists with opioids or alpha 2-agonists have been proved, at the moment their use in man by the spinal route is not advisable because of the absence of adequate studies on their neurotoxicity and adverse effects.

    The deep cervical extensor, semispinalis cervicis, displays changes in behaviour and structure in people with chronic neck pain yet there is limited knowledge on how activation of this muscle can be emphasized during training. Using intramuscular electromyography (EMG), this study investigated the activity of the deep semispinalis cervicis and the superficial splenius capitis muscle at two spinal levels (C2 and C5) in ten healthy volunteers during a series of neck exercises: 1. Traction and compression, 2. Resistance applied in either flexion or extension at the occiput, at the level of the vertebral arch of C1 and of C4, and 3. Maintaining the neck in neutral while inclined on the elbows, with and without resistance at C4. The ratio between semispinalis cervicis and the splenius capitis EMG amplitude was quantified as an indication of whether the exercise could emphasize the activation of the semispinalis cervicis muscle relative to the splenius capitis. Manual resistance applied in extension over the vertebral arch emphasized the activation of the semispinalis cervicis relative to the splenius capitis at the spinal level directly caudal to the site of resistance (ratio: 2.0 ± 1.1 measured at C5 with resistance at C4 and 2.1 ± 1.2 measured at C2 with resistance at C1). This study confirmed the possibility of emphasizing the activation of the semispinalis cervicis relative to the splenius capitis which may be relevant for targeted exercise interventions for this deep extensor muscle. Further studies are required to investigate the clinical efficacy of these exercises for people with neck pain. PMID:25935795

    Patients with vertebral osteomyelitis may require instrumentation for spinal stabilization. Determining the optimal duration and type of antimicrobial therapy for these patients is challenging. The aim of this study was to examine risk factors for treatment failure, in particular antimicrobial duration, in a cohort of patients requiring spinal instrumentation for vertebral osteomyelitis. We conducted a retrospective cohort study of all patients with vertebral osteomyelitis who had spinal instrumentation between January 2002 and January 2012 at the University of Maryland Medical Center. The primary outcome measure was treatment failure >4 weeks postoperatively. We identified 131 patients with vertebral osteomyelitis requiring spinal instrumentation, 94 of whom had >4 weeks of follow-up and were included in the primary analysis. Treatment failure occurred in 22 of the 94 patients (23%) at a median of 4 months after surgery. Among patients who failed therapy, 20 of 22 failed within 1 year of surgery. Cervical and thoracic infection sites and the presence of negative cultures were associated with fewer treatment failures. Addition of rifampin and the use of chronic suppressive antimicrobials did not affect treatment failure rate. Twenty-three percent of patients with spinal instrumentation for vertebral osteomyelitis experienced treatment failure. Treatment failure almost always occurred within the first year of spinal instrumentation. PMID:24277039

    Objective The aim of this review is to elucidate the biochemical, molecular, immunological, and pharmaceutical mechanisms of action of ozone dissolved in biological fluids. Studies performed during the last two decades allow the drawing of a comprehensive framework for understanding and recommending the integration of ozone therapy for spinal pain. Methods An in-depth screening of primary sources of information online – via SciFinder Scholar, Google Scholar, and Scopus databases as well as Embase, PubMed, and the Cochrane Database of Systemic Reviews – was performed. In this review, the most significant papers of the last 25 years are presented and their proposals critically evaluated, regardless of the bibliometric impact of the journals. Results The efficacy of standard treatments combined with the unique capacity of ozone therapy to reactivate the innate antioxidant system is the key to correcting the oxidative stress typical of chronic inflammatory diseases. Pain pathways and control systems of algesic signals after ozone administration are described. Conclusion This paper finds favors the full insertion of ozone therapy into pharmaceutical sciences, rather than as either an alternative or an esoteric approach. PMID:26028964

    Excessive alcohol use can cause harmful effects on the human body, which are associated with serious health problems, and it can also lead to the development of alcohol use disorders (AUDs). There is certain evidence that physical exercise positively affects excessive alcohol use and the associated problems by leading to reduced alcohol intake. A literature search was conducted using the databases PubMed, Medline and Web of Science. The search terms used as keywords were: Addiction, abuse, alcohol use disorders, exercise training, β-endorphin, opioids, brain, ethanol and alcohol. The current study presents the studies that reported on the use of exercise in the treatment of AUDs between 1970 and 2015. The potential psychological and physiological mechanisms that contribute to the action of exercise were also reviewed, highlighting the role of β-endorphin and the hypothalamic-pituitary-adrenal axis in AUDs and the possible association among physical activity, the endogenous opioid system and the desire for alcohol. Only 11 studies were identified that refer to the effect of exercise on alcohol consumption and/or the associated outcomes. Six of those studies concluded that exercise may have a positive impact towards alcohol consumption, abstinence rates or the urge to drink. One of those studies also indicated that a bout of exercise affects the endogenous opioids, which may be associated with the urge to drink. Another 3 studies indicated that responses to acute exercise in individuals with AUDs are different compared to those in healthy ones. Generally, despite limited research data and often contradictory results, there is certain early promising evidence for the role of exercise as an adjunctive tool in the treatment of AUDs. Physiological and biochemical parameters that would confirm that exercise is safe for individuals with AUDs should be examined in future studies. PMID:27123244

  13. Silk peptide treatment can improve the exercise performance of mice

    2014-01-01

    Background We previously reported that silk peptide (SP) treatment led to increased resting fat oxidation in exercised mice. However, it was not known whether SP treatment could effectively increase exercise capacity. Accordingly, this study aimed to examine whether SP treatment affected energy metabolism during exercise in addition to exercise performance. Methods We randomized 36 7-week-old male ICR mice into 2 groups: the control (n = 18) and SP (n = 18) groups. All mice were trained by treadmill running 5 times per week for 2 weeks. SP was dissolved in distilled water and daily 800-mg/kg body weight doses before the running exercise were oral administered intraperitoneally to the SP group for 2 weeks. V˙O2max was measured before and after the 2 weeks training period. We also assessed energy metabolism during exercise for 1 h after the 2 week training period. In addition to blood samples, liver glycogen and gastrocnemius-white and gastrocnemius-red muscle was obtained at the following 3 time points: at rest, immediately after exercise, and 1-hour post exercise. Results The V˙O2 max after 2 weeks of training was significantly increased (8%) in the SP group compared to the baseline; a similar result was not observed in the CON group. The sum of fat oxidation during a 1-h period tended to be 13% higher in the SP group than in the CON group (P < 0.077). In particular, the sum of fat oxidation was significantly higher in the SP group during the initial 20-min phase than that in the CON group (P < 0.05). The glycogen concentration in the white gastrocnemius muscle did not differ between the groups either rest or after 1 h of exercise but was significantly higher in the SP group than in the CON group during the recovery period (1 h post-exercise completion). Conclusions These results suggest that SP treatment can improve the exercise performance. Therefore, SP is considered to confer beneficial effects upon athletes, in whom exercise abilities

    Tissue engineering approaches to spinal cord injury (SCI) treatment are attractive because they allow for manipulation of native regeneration processes involved in restoration of the integrity and function of damaged tissue. A clinically relevant spinal cord regeneration animal model requires that the model mimics specific pathologic processes that occur in human SCI. This manuscript discusses issues related to preclinical testing of tissue engineering spinal cord regeneration strategies from a number of perspectives. This discussion includes diverse causes, pathology and functional consequences of human SCI, general and species related considerations, technical and animal care considerations, and data analysis methods.

    The practical importance, prevalence, typical features, physiopathology and therapy of exercise-induced bronchospasm (E.I.B.) are briefly reviewed. The condition is common, especially in children. Prevalence is influenced by the mode, intensity and duration of exercise, the age and possibly the sex of the subjects, the number of test repetitions, and the criterion for presence of spasm. The main site of obstruction is in the large airways. Symptoms appear a few minutes post-effort, peaking 10-15 minutes after exercise. At different times, spasm may arise in the vagal reflex arc, from alterations of sympathetic balance, prostaglandin release, and sensitization of the mast cell. Until recently, the main basis of prophylaxis has been inhalation of sodium cromoglycate (20 mg, 60 minutes prior to competition). Beta agonists have until recently been prohibited in international competitions. However, the use of selective beta agonists such as salbutamol and terbutaline was allowed in the 1978 World Swimming Championship and the 1980 World Cross-Country Championship with a supporting medical letter. The Medical Commission of the International Olympic Committee has also moved recently to sanction the use of salbutamol and terbutaline. Future prophylaxis will thus be based on combinations of selective beta agonists and sodium cromoglycate. PMID:6794921

    This study examined the effect of a 1 h, self-paced handcycling time trial on blood leukocytes, mucosal immunity, and markers of stress in paraplegic athletes. Nine male paraplegic athletes (spinal injury level thoracic 4-lumbar 2) performed 1 h of handcycling exercise on a standard 400 m athletics track. Heart rate (HR) was measured continuously during exercise, and a retrospective rating of perceived exertion (RPE) was obtained immediately after. Venous blood and saliva samples were collected immediately before exercise (Pre-Ex), after exercise (End-Ex), and 1 h postexercise (1-h Post). The athletes completed mean +/- standard error of mean 22.4 +/- 1.1 km cycling at HR 165 +/- 2 beats/min, RPE 15 +/- 1, and blood lactate 7.9 +/- 2.5 mmol/L. Total leukocytes increased 72% and neutrophils increased 74% End-Ex; both remained elevated at 1-h Post (both p < 0.05). Lymphocytes increased 53% and natural killer cells increased 175% End-Ex (both p < 0.05), but returned to near baseline levels 1-h Post. Increases (p < 0.05) were observed End-Ex in alpha-amylase activity (p < 0.05), which returned to baseline at 1-h Post, but there was no significant change in saliva flow rate, salivary immunoglobulin A, or cortisol. These data confirm that 1 h of handcycling exercise elevated circulating leukocytes but had a minimal effect on mucosal immunity. These changes appear to be associated with alpha-amylase rather than cortisol. PMID:23299262

    Knockdown of spinal metabotropic glutamate 5 (mGlu5) receptor was shown to inhibit the development of intrathecal morphine antinociceptive tolerance. The present work was designed to evaluate the expression of spinal G-protein during morphine tolerance and knockdown of spinal mGlu5 receptor with antisense oligonucleotide (ODN). Rats were treated with saline, morphine, mGlu5 receptor antisense or mismatch ODN intrathecally. Behavioral tests were employed to test the thermal and mechanical pain thresholds. Five days later, rats were scarified and spinal expression of spinal Gαi, Gαo, Gαq and Gβ were detected. Consistent with the previous results, knockdown of spinal mGlu5 receptor could inhibit spinal morphine antinociceptive tolerance in behavioral tests (P<0.05). The mGlu5 receptor antisense ODN produced a significant reduction in mGlu5 receptor protein of about 56.6% compared with the control group (P<0.05). Expression of spinal Gαi, Gαo, Gαq and Gβ were up-regulated while morphine tolerance developed (P<0.05). Antisense ODN of spinal mGlu5 receptor, but not mismatched ODN, reduced the spinal dorsal horn levels of Gαi, Gαo, Gαs, Gαq and Gβ (P<0.05). We conclude that expression of spinal G (αi, αo, αs, αq and β) protein may be up-regulated after chronic morphine treatment which could be attenuated by knockdown of spinal mGlu5 receptor with antisense ODN.

    [Purpose] The purpose of this study was to measure and observe the changes in dynamic plantar pressures when school children carried specific bag loads, and to determine whether improved physical balance after an eight-week spinal stabilization exercise program can influences plantar pressures. [Subjects] The subjects were 10 school students with Cobb angles of 10° or greater. [Methods] Gait View Pro 1.0 (Alfoots, Korea) was were based on to measure the pressure of the participants' feet. Spinal stabilization exercises used TOGU Multi-roll Functional (TOGU, Germany) training. Dynamic plantar pressures were measured with bag loads of 0% no bag and 15% of subjects' body weight. The independent t test was performed to analyze changes in plantar pressures. [Results] The plantar pressure measurements of bag load of 0% of subjects' body weight before and after the spinal stabilization exercise program were not significantly different, but those of two foot areas with a 15% load were statistically significant (mt5, 67.32±24.25 and 51.77±25.52 kPa; lat heel, 126.00±20.46 and 102.08±23.87 kPa). [Conclusion] After performance of the spinal stabilization exercises subjects' overall plantar pressures were reduced, which may suggest that physical balance improved. PMID:26311964

    Objective To test the effectiveness of a high-dose home exercise/telerehabilitation program for manual wheelchair users who have a spinal cord injury (SCI) and determine whether the intervention would reduce pain and increase function, as we hypothesized. Design A pre-post trial with outcomes measured at 3 time points: baseline, postintervention (12wk), and follow-up (24+ weeks). Setting Subjects performed an exercise program at their homes using telerehabilitation for therapist monitoring of technique and exercise advancement. Baseline and postintervention data were collected at a motion analysis laboratory in a tertiary medical center. Participants A convenience sample of manual wheelchair users (N = 16, 3 women; average age, 41y; average time in a wheelchair, 16y) with shoulder pain (average pain duration, 9y) and mechanical impingement signs on physical examination. Interventions A 12-week home exercise program of rotator cuff and scapular stabilization exercises was given to each participant. The program included a high dose of 3 sets of 30 repetitions, 3 times weekly, and regular physical therapist supervision via videoconferencing. Main Outcome Measures Primary outcomes of pain and function were measured with the Wheelchair User's Shoulder Pain Index (WUSPI), Disabilities of Arm, Shoulder, and Hand (DASH) Index, and Shoulder Rating Questionnaire (SRQ). Secondary outcomes of strength were measured with isometric strength tests of scapulothoracic and glenohumeral muscles, and a static fatigue test of the lower trapezius. Results Pain was reduced and function improved after the intervention. There was a significant main effect for pain and function between the 3 time points based on the Friedman signed-ranked test, WUSPI (χ22 = 5.10, P = .014), DASH Index (χ22 = 5.41, P = .012), and SRQ (χ22 = 23.71, P ≤.001).

    Vascular improvements in the nonactive regions during exercise are likely primarily mediated by increased shear rate (SR). Individuals with spinal cord injury (SCI) experience sublesional vascular deconditioning and could potentially benefit from upper body exercise-induced increases in lower body SR. The present study utilized a single bout of incremental arm-crank exercise to generate exercise-induced SR changes in the superficial femoral artery in an effort to evaluate the acute postexercise impact on superficial femoral artery endothelial function via flow-mediated dilation (FMD), and determine regulatory factors in the nonactive legs of individuals with and without SCI. Eight individuals with SCI and eight age, sex, and waist-circumference-matched able-bodied (AB) controls participated. Nine minutes of incremental arm-crank exercise increased superficial femoral artery anterograde SR (P = 0.02 and P < 0.01), retrograde SR (P < 0.01 and P < 0.01), and oscillatory shear index (OSI) (P < 0.001 and P < 0.001) in both SCI and AB, respectively. However, these SR alterations resulted in acute postexercise increases in FMD in the AB group only (SCI 6.0 ± 1.2% to 6.3 ± 2.7%, P = 0.74; AB 7.5 ± 1.4% to 11.2 ± 1.4%, P = 0.03). While arm exercise has many cardiovascular benefits and results in changes in SR patterns in the nonactive legs, these changes are not sufficient to induce acute changes in FMD among individuals with SCI, and therefore are less likely to stimulate exercise training-associated improvements in nonactive limb endothelial function. Understanding the role of SR patterns on FMD brings us closer to designing effective strategies to combat impaired vascular function in both healthy and clinical populations. PMID:25847920

    Scoliosis is the abnormal lateral curvature and rotation of the spine. In the past this deformity has been linked with moral depravity, as in the case of Richard III. Treatment for scoliosis began with Hippocrates's use of boards and axial distortion. Today, bracing and surgery are used either to correct the deformity or to prevent further progression. In the past, however, exercise regimens have been used in the belief that strengthening back muscles would reduce curvature progression. This approach was pioneered by Per Henrik Ling in the early nineteenth century and was continued by his followers Mathius Roth and Franz Berwald and, most notably, by Gustav Zander. Even today a few clinics, particularly in Eastern Europe, still use exercise in the treatment of scoliosis. Whether it is effective remains debatable, but even if progression is not prevented the patient's general health will benefit from an exercise regimen. PMID:25318403

    Purpose: Spinal stereotactic body radiation therapy (SBRT) continues to emerge as an effective therapeutic approach to spinal metastases; however, treatment planning and delivery remain resource intensive at many centers, which may hamper efficient implementation in clinical practice. We sought to develop a generalizable class solution approach for spinal SBRT treatment planning that would allow confidence that a given plan provides optimal target coverage, reduce integral dose, and maximize planning efficiency. Methods and Materials: We examined 91 patients treated with spinal SBRT at our institution. Treatment plans were categorized by lesion location, clinical target volume (CTV) configuration, and dose fractionation scheme, and then analyzed to determine the technically achievable dose gradient. A radial cord expansion was subtracted from the CTV to yield a planning CTV (pCTV) construct for plan evaluation. We reviewed the treatment plans with respect to target coverage, dose gradient, integral dose, conformality, and maximum cord dose to select the best plans and develop a set of class solutions. Results: The class solution technique generated plans that maintained target coverage and improved conformality (1.2-fold increase in the 95% van't Riet Conformation Number describing the conformality of a reference dose to the target) while reducing normal tissue integral dose (1.3-fold decrease in the volume receiving 4 Gy (V{sub 4Gy}) and machine output (19% monitor unit (MU) reduction). In trials of planning efficiency, the class solution technique reduced treatment planning time by 30% to 60% and MUs required by {approx}20%: an effect independent of prior planning experience. Conclusions: We have developed a set of class solutions for spinal SBRT that incorporate a pCTV metric for plan evaluation while yielding dosimetrically superior treatment plans with increased planning efficiency. Our technique thus allows for efficient, reproducible, and high-quality spinal

    Following central motor lesions, two forms of adaptation can be observed which lead to improved mobility: (1) the development of spastic muscle tone, and (2) the activation of spinal locomotor centers induced by specific treadmill training. Tension development during spastic gait is different from that during normal gait and appears to be independent of exaggerated monosynaptic stretch reflexes. Exaggerated stretch reflexes are associated with an absence or reduction of functionally essential polysynaptic reflexes. When supraspinal control of spinal reflexes is impaired, the inhibition of monosynaptic reflexes is missing in addition to a reduced facilitation of polysynaptic reflexes. Therefore, overall leg muscle activity becomes reduced and less well modulated in patients with spasticity. Electrophysiologicai and histological studies have shown that a transformation of motor units takes place following central motor lesions with the consequence that regulation of muscle tone is achieved at a lower level of neuronal organization which in turn enables the patient to walk. Based on observations of the locomotor capacity of the spinal cat, recent studies have indicated that spinal locomotor centers can be activated and trained in patients with complete or incomplete paraplegia when the body is partially unloaded. However, the level of electromyographic activity in the gastrocnemius (the main antigravity muscle during gait) is considerably lower in the patients compared to healthy subjects. During the course of a daily locomotor training program, the amplitude of gastrocnemius, electromyographic activity increases significantly during the stance phase, while inappropriate tibialis anterior activation decreases. Patients with incomplete paraplegia benefit from such training programs such that their walking ability on a stationary surface improves.

    Spinal cord injury (SCI) often results in some form of paralysis. Recently, SCI therapy has been focused on preventing secondary injury to reduce both neuroinflammation and lesion size so that functional outcome after an SCI may be improved. Previous studies have shown that adenosine receptors (AR) are a major regulator of inflammation after an SCI. The current study was performed to examine the effect of caffeine, a pan-AR blocker, on spontaneous functional recovery after an SCI. Animals were assigned into 3 groups randomly, including sham, PBS and caffeine groups. The rat SCI was generated by an NYU impactor with a 10 g rod dropped from a 25 mm height at thoracic 9 spinal cord level. Caffeine and PBS were injected daily during the experiment period. Hind limb motor function was evaluated by the Basso, Beattie, Bresnahan (BBB) locomotor rating scale at 1 week and 4 weeks after the SCI. Spinal cord segments were collected after final behavior evaluation for morphological analysis. The tissue sparing was evaluated by luxol fast blue staining. Immunofluorescence stain was employed to assess astrocyte activation and neurofilament positioning, while microglia activation was examined by immunohistochemistry stain.The results showed that spontaneous functional recovery was blocked after the animals were subjected caffeine daily. Moreover, caffeine administration increased the demyelination area, promoted astrocyte and microglia activation and decreased the quantity of neurofilaments. These findings suggest that the neurotoxicity effect of caffeine may be associated with the inhibition of neural repair and the promotion of neuroinflammation. PMID:26746340

Overview of Literature Snowboarding-related spinal or spinal cord injury have a great impact on social and sporting activities. Methods A retrospective review of 19 cases of surgically treated snowboard-related injury was done. Analyzed parameters included site of injury, type of fracture, peri- and postoperative complications, pre- and postoperative neurological status, activities of daily living, and participation in sports activities at the final follow-up. Results The major site of injury was the thoracolumbar junction caused by fracture-dislocation (13/19 cases). The remaining 6 cases had cervical spine injuries. Over 60% of the patients had Frankel A and B paralysis. All patients were surgically treated by posterior fusion with instrumentation. Five underwent additional anterior fusion. Surgical outcome was restoration of ambulatory capacity in 12 patients (63.2%). Ultimately, 15 patients (78.9%) could return to work. Patients with complete paralysis upon admission showed reduced ambulatory capacity compared to those with incomplete paralysis. None of the patients again participated in any sports activities, including snowboarding. Conclusions Snowboarding-related spinal or spinal cord injury has a great impact on social as well as sports activities. It is necessary to enhance promotion of injury prevention emphasizing the snowboarders' responsibility code. PMID:25705340

    OBJECTIVE The microvascular anatomy of spinal perimedullary arteriovenous fistulas (AVFs) is more complicated than that of dural AVFs, and occlusion rates of AVF after open microsurgery or endovascular embolization are lower in patients with perimedullary AVFs (29%-70%) than they are in those with dural AVF (97%-98%). Reports of intraoperative blood flow assessment using indocyanine green (ICG) video angiography in spinal arteriovenous lesions have mostly been for spinal dural AVFs. No detailed reports on spinal perimedullary AVFs are available. METHODS Participants were 11 patients with spinal perimedullary AVFs (Type IVa in 5 patients, Type VIb in 4, and Type IVc in 2). Intraoperative ICG video angiography was assessed by measuring the number of cases in which this modality was judged essential by the surgeon to correctly occlude the fistula. RESULTS In all patients, arterial feeders were identified and intravenous ICG video angiography was performed before and after blocking the feeders. In one patient, selective intraarterial ICG video angiography was also performed. The findings provided by ICG video angiography significantly changed the surgical procedure in 4 of 11 patients (36%). Postoperatively, complete occlusion of the AVF was achieved in 10 of the 11 patients (91%). CONCLUSIONS Intraoperative ICG video angiography can have a significant impact on deciding surgical strategy in the microsurgical treatment of spinal perimedullary AVF. PMID:26926050

    Study Design Single group, pretest-posttest study. Objectives To determine the effects of a non-task-specific, voluntary, progressive aerobic exercise training (AET) intervention on fitness and walking-related outcomes in ambulatory adults with chronic motor-incomplete SCI. Setting Rehabilitation research center. Methods Ten ambulatory individuals (50% female; 57.94 ± 9.33 years old; 11.11 ± 9.66 years post injury) completed voluntary, progressive moderate-to-vigorous intensity AET on a recumbent stepper three days per week for six weeks. The primary outcome measures were aerobic capacity (VO2peak) and self-selected overground walking speed (OGWS). Secondary outcome measures included: walking economy, six-minute walk test (6MWT), daily step counts, Walking Index for Spinal Cord Injury (WISCI-II), Dynamic Gait Index (DGI), and Berg Balance Scale (BBS). Results Nine participants completed all testing and training. Significant improvements in aerobic capacity (P=0.011), OGWS (P=0.023), the percentage of VO2peak utilized while walking at self-selected speed (P=0.03), and daily step counts (P=0.025) resulted following training. Conclusions The results indicate that total-body, voluntary, progressive AET is safe, feasible, and effective for improving aerobic capacity, walking speed, and select walking-related outcomes in an exclusively ambulatory SCI sample. This study suggests the potential for non-task-specific aerobic exercise to improve walking following incomplete SCI and builds a foundation for further investigation aimed at the development of exercise based rehabilitation strategies to target functionally limiting impairments in ambulatory individuals with chronic SCI.

    Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tuberculosis. However, high risk of structural damage might relate with anterior surgery, such as damage in lungs, heart, kidney, ureter and bowel, and the deformity correction is also limited. Due to the organs are in the front of spine, there are less complications in posterior approach. Spinal pedicle screw passes through the spinal three-column structure, which provides more powerful orthopedic forces compared with the vertebral body screw, and the kyphotic deformity correction effect is better in posterior approach. In this paper, we report a 68-year-old male patient with thoracic tuberculosis who underwent surgical treatment by debridement, interbody fusion and internal fixation via posterior approach only. The patient was placed in prone position under general anesthesia. Posterior midline incision was performed, and the posterior spinal construction was exposed. Then place pedicle screw, and fix one side rod temporarily. Make the side of more bone destruction and larger abscess as lesion debridement side.

    Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tuberculosis. However, high risk of structural damage might relate with anterior surgery, such as damage in lungs, heart, kidney, ureter and bowel, and the deformity correction is also limited. Due to the organs are in the front of spine, there are less complications in posterior approach. Spinal pedicle screw passes through the spinal three‐column structure, which provides more powerful orthopedic forces compared with the vertebral body screw, and the kyphotic deformity correction effect is better in posterior approach. In this paper, we report a 68‐year‐old male patient with thoracic tuberculosis who underwent surgical treatment by debridement, interbody fusion and internal fixation via posterior approach only. The patient was placed in prone position under general anesthesia. Posterior midline incision was performed, and the posterior spinal construction was exposed. Then place pedicle screw, and fix one side rod temporarily. Make the side of more bone destruction and larger abscess as lesion debridement side. Resect the unilateral facet joint, and retain contralateral structure integrity. Protect the spinal cord, nerve root. Clear sequestrum, necrotic tissue, abscess of paravertebral and intervertebral space. Specially designed titanium mesh cages or bone blocks were implanted into interbody.

    Context: Lumbar central spinal stenosis is common and often results in chronic persistent pain and disability, which can lead to multiple interventions. After the failure of conservative treatment, either surgical or nonsurgical modalities such as epidural injections are contemplated in the management of lumbar spinal stenosis. Evidence Acquisition: Recent randomized trials, systematic reviews and guidelines have reached varying conclusions about the efficacy of epidural injections in the management of central lumbar spinal stenosis. The aim of this systematic review was to determine the efficacy of all three anatomical epidural injection approaches (caudal, interlaminar, and transforaminal) in the treatment of lumbar central spinal stenosis. A systematic review was performed on randomized trials published from 1966 to July 2014 of all types of epidural injections used in the management of lumbar central spinal stenosis. Methodological quality assessment and grading of the evidence was performed. Results: The evidence in managing lumbar spinal stenosis is Level II for long-term improvement for caudal and lumbar interlaminar epidural injections. For transforaminal epidural injections, the evidence is Level III for short-term improvement only. The interlaminar approach appears to be superior to the caudal approach and the caudal approach appears to be superior to the transforaminal one. Conclusions: The available evidence suggests that epidural injections with local anesthetic alone or with local anesthetic with steroids offer short- and long-term relief of low back and lower extremity pain for patients with lumbar central spinal stenosis. However, the evidence is Level II for the long-term efficacy of caudal and interlaminar epidural injections, whereas it is Level III for short-term improvement only with transforaminal epidural injections.

    Spinal cord injury in DCS after air diving is relatively frequent and often has late sequelae. U.S. Navy oxygen tables are sometimes not satisfactory. The advantage of using helium in these cases is based theoretically on its physical properties and has been demonstrated in animal models. We have introduced the Comex-30 (CX-30) oxy-helium table as an integral part of our treatment protocol for severe spinal DCS. We summarize here our clinical experience with seven cases. A case was considered severe if clinical assessment suggested progressive neurologic injury to the spinal cord or roots. Except for one case, the initial treatment was CX-30 followed by HBO sessions as indicated. Of the seven patients treated, five made a full recovery and the remaining two were left with mild neurologic sequelae. PMID:8329941

    Histone acetylation plays an important role in regulation of transcription in eukaryotic cells by promoting a more relaxed chromatin structure necessary for transcriptional activation. Histone deacetylases (HDACs) remove acetyl groups and suppress gene expression. HDAC inhibitors (HDACIs) are a group of small molecules that promote gene transcription by chromatin remodeling and have been extensively studied as potential drugs for treating of spinal muscular atrophy. Various drugs in this class have been studied with regard to their efficacy in increasing the expression of survival of motor neuron (SMN) protein. In this review, we discuss the current literature on this topic and summarize the findings of the main studies in this field. PMID:24130434

    Mitochondrial myopathies are caused by genetic mutations that directly influence the functioning of the electron transport chain (ETC). It is estimated that 1 of 8,000 people have pathology inducing mutations affecting mitochondrial function. Diagnosis often requires a multifaceted approach with measurements of serum lactate and pyruvate, urine organic acids, magnetic resonance spectroscopy (MRS), muscle histology and ultrastructure, enzymology, genetic analysis, and exercise testing. The ubiquitous distribution of the mitochondria in the human body explains the multiple organ involvement. Exercise intolerance is a common but often an overlooked hallmark of mitochondrial myopathies. The muscle consequences of ETC dysfunction include increased reliance on anaerobic metabolism (lactate generation, phosphocreatine degradation), enhanced free radical production, reduced oxygen extraction and electron flux through ETC, and mitochondrial proliferation or biogenesis (see article by Hood in current issue). Treatments have included antioxidants (vitamin E, alpha lipoic acid), electron donors and acceptors (coenzyme Q10, riboflavin), alternative energy sources (creatine monohydrate), lactate reduction strategies (dichloroacetate) and exercise training. Exercise is a particularly important modality in diagnosis as well as therapy (see article by Taivassalo in current issue). Increased awareness of these disorders by exercise physiologists and sports medicine practitioners should lead to more accurate and more rapid diagnosis and the opportunity for therapy and genetic counseling.

    Tumours of the spinal cord, although rare, are associated with high morbidity. Surgical resection remains the primary treatment for patients with this disease, and offers the best chance for cure. Such surgical procedures, however, carry substantial risks such as worsening of neurological deficit, paralysis and death. New therapeutic avenues for spinal cord tumours are needed, but genetic studies of the molecular mechanisms governing tumourigenesis in the spinal cord are limited by the scarcity of high-quality human tumour samples. Many spinal cord tumours have intracranial counterparts that have been extensively studied, but emerging data show that the tumours are genetically and biologically distinct. The differences between brain and spine tumours make extrapolation of data from one to the other difficult. In this Review, we describe the demographics, genetics and current treatment approaches for the most commonly encountered spinal cord tumours—namely, ependymomas, astrocytomas, haemangioblastomas and meningiomas. We highlight advances in understanding of the biological basis of these lesions, and explain how the latest progress in genetics and beyond are being translated to improve patient care.

    Background. Spinal metastases frequently arise in patients with cancer. Modern oncology provides numerous treatment options that include effective systemic, radiation, and surgical options. We delineate and provide the evidence for the neurologic, oncologic, mechanical, and systemic (NOMS) decision framework, which is used at Memorial Sloan-Kettering Cancer Center to determine the optimal therapy for patients with spine metastases. Methods. We provide a literature review of the integral publications that serve as the basis for the NOMS framework and report the results of systematic implementation of the NOMS-guided treatment. Results. The NOMS decision framework consists of the neurologic, oncologic, mechanical, and systemic considerations and incorporates the use of conventional external beam radiation, spinal stereotactic radiosurgery, and minimally invasive and open surgical interventions. Review of radiation oncology and surgical literature that examine the outcomes of treatment of spinal metastatic tumors provides support for the NOMS decision framework. Application of the NOMS paradigm integrates multimodality therapy to optimize local tumor control, pain relief, and restoration or preservation of neurologic function and minimizes morbidity in this often systemically ill patient population. Conclusion. NOMS paradigm provides a decision framework that incorporates sentinel decision points in the treatment of spinal metastases. Consideration of the tumor sensitivity to radiation in conjunction with the extent of epidural extension allows determination of the optimal radiation treatment and the need for surgical decompression. Mechanical stability of the spine and the systemic disease considerations further help determine the need and the feasibility of surgical intervention. PMID:23709750

    STUDY DESIGN Single-blind randomized trial. OBJECTIVES To compare the effects of cervical and shoulder thrust manipulation (TM) and exercise on pain sensitivity, and to explore associations with clinical outcomes in patients with shoulder pain. BACKGROUND Experimental studies indicate that spinal TM has an influence on central pain processes, supporting its application for treatment of extremity conditions. Direct comparison of spinal and peripheral TM on pain sensitivity has not been widely examined. METHODS Seventy-eight participants with shoulder pain (36 female; mean ± SD age, 39.0 ± 14.5 years) were randomized to receive 3 treatments of cervical TM (n = 26), shoulder TM (n = 27), or shoulder exercise (n = 25) over 2 weeks. Twenty-five healthy participants (13 female; mean ± SD age, 35.2 ± 11.1 years) were assessed to compare pain sensitivity with that in clinical participants at baseline. Primary outcomes were changes in local (eg, shoulder) and remote (eg, tibialis anterior) pressure pain threshold and heat pain threshold occurring over 2 weeks. Secondary outcomes were shoulder pain intensity and patient-rated function at 4, 8, and 12 weeks. Analysis-of-variance models and partial-correlation analyses were conducted to examine comparative effects and the relationship between measures. RESULTS At baseline, clinical participants demonstrated lower local (mean difference, −1.63 kg; 95% confidence interval [CI]: −2.40, −0.86) and remote pressure pain threshold (mean difference, −1.96 kg; 95% CI: −3.09, −0.82) and heat pain threshold (mean difference, −1.15°C; 95% CI: −2.06, −0.24) compared to controls, suggesting enhanced pain sensitivity. Following intervention, there were no between-group differences in pain sensitivity or clinical outcome (P>.05). However, improvements were noted, regardless of intervention, for pressure pain threshold (range of mean differences, 0.22–0.32 kg; 95% CI: 0.03, 0.43), heat pain threshold (range of mean

    We examined the effect of high-load fly-wheel (targeting the lower-limb musculature and concurrent loading of the spine via shoulder restraints) and spinal movement countermeasures against lumbar spine muscle atrophy, disc and spinal morphology changes and trunk isokinetic torque loss during prolonged bed-rest. Twenty-four male subjects underwent 90 d head-down tilt bed-rest and performed either fly-wheel (FW) exercises every three days, spinal movement exercises in lying five times daily (SpMob), or no exercise (Ctrl). There was no significant impact of countermeasures on losses of isokinetic trunk flexion/extension ( p≥0.65). Muscle volume change by day-89 of bed-rest in the psoas, iliacus, lumbar erector spinae, lumbar multifidus and quadratus lumborum, as measured via magnetic resonance imaging (MRI), was statistically similar in all three groups ( p≥0.33). No significant effect on MRI-measures of lumbar intervertebral disc volume, spinal length and lordosis ( p≥0.09) were seen either, but there was some impact ( p≤0.048) on axial plane disc dimensions (greater reduction than in Ctrl) and disc height (greater increases than in Ctrl). MRI-data from subjects measured 13 and 90-days after bed-rest showed partial recovery of the spinal extensor musculature by day-13 after bed-rest with this process complete by day-90. Some changes in lumbar spine and disc morphology parameters were still persistent 90-days after bed-rest. The present results indicate that the countermeasures tested were not optimal to maintain integrity of the spine and trunk musculature during bed rest.

    Background Interspinous distraction devices (IPDD) are indicated as stand-alone devices for the treatment of spinal stenosis. The purpose of this study is to evaluate the results of patients undergoing surgery for spinal stenosis with a combination of unilateral microdecompression and interspinous distraction device insertion. Methods This is a prospective clinical and radiological study of minimum 2 years follow-up. Twenty-two patients (average age 64.5 years) with low-back pain and unilateral sciatica underwent decompressive surgery for lumbar spinal stenosis. Visual Analogue Scale, Oswestry Disability Index and walking capacity plus radiologic measurements of posterior disc height of the involved level and lumbar lordosis Cobb angle were documented both preoperatively and postoperatively. One-sided posterior subarticular and foraminal decompression was conducted followed by dynamic stabilization of the diseased level with an IPDD (X-STOP). Results The average follow-up time was 27.4 months. Visual Analogue Scale and Oswestry Disability Index improved statistically significantly (p < 0.001) in the last follow-up exam. Also, the walking distance increased in all patients but two. Posterior intervertebral disc height of the diseased level widened average 1.8 mm in the postoperative radiograph compared to the preoperative. No major complication, including implant failure or spinous process breakage, has been observed. Conclusions The described surgical technique using unilateral microdecompression and IPDD insertion is a clinically effective and radiologically viable treatment method for symptoms of spinal stenosis resistant to non-operative treatment.

    With no currently available drug treatment for spinal cord injury, there is a need for additional therapeutic candidates. We took the approach of repositioning existing pharmacological agents to serve as acute treatments for spinal cord injury and previously found imatinib to have positive effects on locomotor and bladder function in experimental spinal cord injury when administered immediately after the injury. However, for imatinib to have translational value, it needs to have sustained beneficial effects with delayed initiation of treatment, as well. Here, we show that imatinib improves hind limb locomotion and bladder recovery when initiation of treatment was delayed until 4 h after injury and that bladder function was improved with a delay of up to 24 h. The treatment did not induce hypersensitivity. Instead, imatinib-treated animals were generally less hypersensitive to either thermal or mechanical stimuli, compared with controls. In an effort to provide potential biomarkers, we found serum levels of three cytokines/chemokines--monocyte chemoattractant protein-1, macrophage inflammatory protein (MIP)-3α, and keratinocyte chemoattractant/growth-regulated oncogene (interleukin 8)--to increase over time with imatinib treatment and to be significantly higher in injured imatinib-treated animals than in controls during the early treatment period. This correlated to macrophage activation and autofluorescence in lymphoid organs. At the site of injury in the spinal cord, macrophage activation was instead reduced by imatinib treatment. Our data strengthen the case for clinical trials of imatinib by showing that initiation of treatment can be delayed and by identifying serum cytokines that may serve as candidate markers of effective imatinib doses.

    Spinal muscular atrophy (SMA), one of the most frequent and devastating genetic disorders causing neuromuscular degeneration, has reached the forefront of clinical translation. The quite unique genetic situation of SMA patients, who lack functional SMN1 but carry the misspliced SMN2 copy gene, creates the possibility of correcting SMN2 splicing by antisense oligonucleotides or drugs. Both strategies showed impressive results in pre-clinical trials and are now in Phase II-III clinical trials. SMN gene therapy approaches using AAV9-SMN vectors are also highly promising and have entered a Phase I clinical trial. However, careful analysis of SMA animal models and patients has revealed some limitations that need to be taken very seriously, including: i) a limited time-window for successful therapy delivery, making neonatal screening of SMA mandatory; ii) multi-organ impairment, requiring systemic delivery of therapies; and iii) a potential need for combined therapies that both increase SMN levels and target pathways that preserve/rescue motor neuron function over the lifespan. Meeting these challenges will likely be crucial to cure SMA, instead of only ameliorating symptoms, particularly in its most severe form. This review discusses therapies currently in clinical trials, the hopes for SMA therapy, and the potential limitations of these new approaches. PMID:25920617

    Thirty years ago, patients with spinal cord injury (SCI) and their families were told "nothing can be done" to improve function. Since the SCI patient population is reaching normal life expectancy through better health care, it has become an obviously worthwhile enterprise to devote considerable research effort to SCI. Targets for intervention in SCI toward improved function have been identified using basic research approaches and can be simplified into a list: (1) reduction of edema and free-radical production, (2) rescue of neural tissue at risk of dying in secondary processes such as abnormally high extracellular glutamate concentrations, (3) control of inflammation, (4) rescue of neuronal/glial populations at risk of continued apoptosis, (5) repair of demyelination and conduction deficits, (6) promotion of neurite growth through improved extracellular environment, (7) cell replacement therapies, (8) efforts to bridge the gap with transplantation approaches, (9) efforts to retrain and relearn motor tasks, (10) restoration of lost function by electrical stimulation, and (11) relief of chronic pain syndromes. Currently, over 70 clinical trials are in progress worldwide. Consequently, in this millennium, unlike in the last, no SCI patient will have to hear "nothing can be done." PMID:12443996

    Novel approaches to the treatment of stimulant abuse and dependence are needed. Clinical data examining the use of exercise as a treatment for the abuse of nicotine, alcohol, and other substances suggest that exercise may be a beneficial treatment for stimulant abuse. In addition, exercise has been associated with improvements in many other health-related areas that may be adversely affected by stimulant use or its treatment, such as sleep disturbance, cognitive function, mood, weight, quality of life, and anhedonia. Neurobiological evidence provides plausible mechanisms by which exercise could positively affect treatment outcomes in stimulant abuse. The National Institute on Drug Abuse (NIDA) Clinical Trials Network (CTN) CTN-0037 Stimulant Reduction Intervention using Dosed Exercise (STRIDE) study is a multisite randomized clinical trial that compares exercise to health education as potential treatments for stimulant abuse or dependence. If effective, exercise may provide an additional approach to the treatment of stimulant use disorders. PMID:25364477

    The study was to investigate the feasibility and effectiveness of posterior-only approach combining with puncture drainage under CT-guide in staged treatment of thoracic and lumbar spinal tuberculosis with flow injection abscess. We retrospectively analyzed 15 patients (came from 72 cases with thoracic and lumbar spinal tuberculosis) with flow injection abscesses underwent surgery from January 2007 to February 2009, and evaluated the American Spinal Injury Association (ASIA) scoring system of nerve function, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), abscess absorption time and the Oswestry Disability Index (ODI), preoperatively and postoperatively. 15 patients were followed up for 13-37 months, no recurrence of tuberculosis, no fixation loosening and neurologic symptoms aggravated. The flow injection abscesses are absorbed within 3-6 months postoperative operation. In final follow-up, ESR went down to 5.2±2.1 mm/h from preoperative 79.6±14.8 mm/h, CRP decreased from preoperative 49.3±7.5 mg/L to 1.8±0.7 mg/L, ODI changed from 75.13±20.15 to 16.72±8.62, all of them changed significantly (P<0.05). In conclusions, one-stage posterior debridement, interbody fusion, pedicle screw fixation and two-stage CT-guided interventional therapy were safe and effective in treatment of the thoracic and lumbar spinal tuberculosis with flow injection abscess.

    Peroxisome Proliferator Activated Receptor (PPAR)-α is a key regulator of lipid metabolism and recent studies reveal it also regulates inflammation in several different disease models. Gemfibrozil, an agonist of PPAR-α, is a FDA approved drug for hyperlipidemia and has been shown to inhibit clinical signs in a rodent model of multiple sclerosis. Since many studies have shown improved outcome from spinal cord injury (SCI) by anti-inflammatory and neuroprotective agents, we tested the efficacy of oral gemfibrozil given before or after SCI for promoting tissue preservation and behavioral recovery after spinal contusion injury in mice. Unfortunately, the results were contrary to our hypothesis; in our first attempt, gemfibrozil treatment exacerbated locomotor deficits and increased tissue pathology after SCI. In subsequent experiments, the behavioral effects were not replicated but histological outcomes again were worse. We also tested the efficacy of a different PPAR-α agonist, fenofibrate, which also modulates immune responses and is beneficial in several neurodegenerative disease models. Fenofibrate treatment did not improve recovery, although there was a slight trend for a modest increase in histological tissue sparing. Based on our results, we conclude that PPAR-α agonists yield either no effect or worsen recovery from spinal cord injury, at least at the doses and the time points of drug delivery tested here. Further, patients sustaining spinal cord injury while taking gemfibrozil might be prone to exacerbated tissue damage. PMID:21963672

    Cancer often metastasizes to the vertebra, and such metastases can be treated successfully using simple, static posterior or opposed-pair radiation fields. However, in some cases, including when re-irradiation is required, spinal cord avoidance becomes necessary and more complex treatment plans must be used. This study evaluated 16 sample intensity-modulated radiation therapy (IMRT) and volumetric-modulated arc therapy (VMAT) treatment plans designed to treat 6 typical vertebral and paraspinal volumes using a standard prescription, with the aim of investigating the advantages and limitations of these treatment techniques and providing recommendations for their optimal use in vertebral treatments. Treatment plan quality and beam complexity metrics were evaluated using the Treatment And Dose Assessor (TADA) code. A portal-imaging-based quality assurance (QA) system was used to evaluate treatment delivery accuracy, and radiochromic film measurements were used to provide high-resolution verification of treatment plan dose accuracy, especially in the steep dose gradient regions between each vertebral target and spinal cord. All treatment modalities delivered approximately the same doses and the same levels of dose heterogeneity to each planning target volume (PTV), although the minimum PTV doses in the vertebral plans were substantially lower than the prescription, because of the requirement that the plans meet a strict constraint on the dose to the spinal cord and cord planning risk volume (PRV). All plans met required dose constraints on all organs at risk, and all measured PTV-cord dose gradients were steeper than planned. Beam complexity analysis suggested that the IMRT treatment plans were more deliverable (less complex, leading to greater QA success) than the VMAT treatment plans, although the IMRT plans also took more time to deliver. The accuracy and deliverability of VMAT treatment plans were found to be substantially increased by limiting the number of monitor

    Cervical spinal cord injury (CSCI) results in a decrease in the capacity of the lungs and chest wall for pressure, volume, and airflow generation. We asked whether such impairments might increase the potential for exercise-induced diaphragmatic fatigue and mechanical ventilatory constraint in this population. Seven Paralympic wheelchair rugby players (mean + or - SD peak oxygen uptake = 16.9 + or - 4.9 ml x kg(-1) x min(-1)) with traumatic CSCI (C(5)-C(7)) performed arm-crank exercise to the limit of tolerance at 90% of their predetermined peak work rate. Diaphragm function was assessed before and 15 and 30 min after exercise by measuring the twitch transdiaphragmatic pressure (P(di,tw)) response to bilateral anterolateral magnetic stimulation of the phrenic nerves. Ventilatory constraint was assessed by measuring the tidal flow volume responses to exercise in relation to the maximal flow volume envelope. P(di,tw) was not different from baseline at any time after exercise (unpotentiated P(di,tw) = 19.3 + or - 5.6 cmH(2)O at baseline, 19.8 + or - 5.0 cmH(2)O at 15 min after exercise, and 19.4 + or - 5.7 cmH(2)O at 30 min after exercise; P = 0.16). During exercise, there was a sudden, sustained rise in operating lung volumes and an eightfold increase in the work of breathing. However, only two subjects showed expiratory flow limitation, and there was substantial capacity to increase both flow and volume (<50% of maximal breathing reserve). In conclusion, highly trained athletes with CSCI do not develop exercise-induced diaphragmatic fatigue and rarely reach mechanical ventilatory constraint. PMID:20489038

    Spinal ependymomas are rare tumours, with total resection favoured where possible. Several case series assessing the outcome following neurosurgical treatment for spinal ependymoma advocate the usage of adjuvant radiotherapy in cases of subtotal resection, or in unencapsulated tumours. We assessed the outcome of 61 consecutive cases of spinal ependymoma in a single centre over a 20year period using a variety of outcome measures. Sex distribution was equal, with a mean age at surgery of 43.6years (range 5-76years). Overall, most tumours occurred in the lumbosacral region (70.5%), with fewer in the thoracic (27.9%) and cervical regions (18.0%). Myxopapillary features were seen in 41.0% of tumours, and were more common when occurring in the lumbar region (51.2%). Gross total resection was achieved in 52.5%, subtotal resection in 37.7% and biopsy alone in 9.8% of patients and 31.1% received adjuvant radiotherapy. Two-thirds of patients achieved an excellent post-operative neurological outcome (Frankel grade E). Tumour recurrence was rare. Gross total resection and good preoperative neurological condition were most strongly predictive of good outcome. Post-operative radiotherapy did not seem to confer survival benefit in this case series, even in cases of incomplete resection, leading us to question its utility for all cases of spinal cord ependymoma.

    Genetic alterations in the cells of intradural spinal tumors can have a significant impact on the treatment options, counseling, and prognosis for patients. Although surgery is the primary therapy for most intradural tumors, radiochemothera-peutic modalities and targeted interventions play an ever-evolving role in treating aggressive cancers and in addressing cancer recurrence in long-term survivors. Recent studies have helped delineate specific genetic and molecular differences between intradural spinal tumors and their intracranial counterparts and have also identified significant variation in therapeutic effects on these tumors. This review discusses the genetic and molecular alterations in the most common intradural spinal tumors in both adult and pediatrie patients, including nerve sheath tumors (that is, neurofibroma and schwannoma), meningioma, ependymoma, astrocytoma (that is, low-grade glioma, anaplastic astrocytoma, and glioblastoma), hemangioblastoma, and medulloblastoma. It also examines the genetics of metastatic tumors to the spinal cord, arising either from the CNS or from systemic sources. Importantly, the impact of this knowledge on therapeutic options and its application to clinical practice are discussed. PMID:26235020

    2010-01-01

    Scoliosis is a common deformity in children and adolescents with cerebral palsy. This is usually associated with pelvic obliquity due to extension of the curve to the sacrum. Sagittal plane deformity is less common and often develops along with scoliosis. Spinal deformity in patients with severe neurological handicaps can affect their ability to sit and cause significant back pain or pain due to rib impingement against the elevated side of the pelvis on the concavity of the curvature. Surgical correction followed by spinal arthrodesis is indicated in patients with progressive deformities which interfere with their level of function and quality of life. Spinal deformity correction is a major task in children with multiple medical co-morbidities and can be associated with a high risk of complications including death. A well-coordinated multidisciplinary approach is required in the assessment and treatment of this group of patients with the aim to minimize the complication rate and secure a satisfactory surgical outcome. Good knowledge of the surgical and instrumentation techniques, as well as the principles of management is needed to achieve optimum correction of the deformity and balancing of the spine and pelvis. Spinal fusion has a well-documented positive impact even in children with quadriplegia or total body involvement and is the only surgical procedure which has such a high satisfaction rate among parents and caregivers.

    Study Design Case series. Background Low back pain (LBP) is an increasing problem in health care. The evidence for the use of spinal manipulative therapy to treat pediatric patients with LBP is minimal. The treatment of pediatrics with manual therapy, particularly spinal manipulation, is controversial within the medical community, primarily with respect to adverse events. The purpose of this case series was to illustrate the feasibility and safety of lumbar manipulation plus exercise in the adolescent population with mechanical LBP. Case Description Three patients-a 13-year-old adolescent girl, 15-year-old adolescent girl, and 13-year-old adolescent boy-were treated in an outpatient physical therapy setting for mechanical LBP. All 3 patients were assessed using a lumbar manipulation clinical prediction rule and treated with sidelying lumbar manipulation and exercise. Outcomes Patients were treated for a total of 10 to 14 visits over a course of 8 to 9 weeks. Pain (measured by a numeric pain-rating scale) and disability (measured by the modified Oswestry Disability Index) improved to 0/10 and 0%, respectively, in each patient. No adverse reactions to manipulation were reported. Discussion The results of this case series describe the use of lumbar thrust manipulation and exercise for the treatment of mechanical LBP in adolescents. The positive results indicate that lumbar manipulation may be a safe adjunct therapy. Further studies, including randomized controlled trials, are needed to determine effectiveness.

    Spinal cord injury (SCI) is a severe condition leading to enduring motor deficits. When lesions are incomplete, promoting spinal cord plasticity might be a useful strategy to elicit functional recovery. Here we investigated whether long-term fluoxetine administration in the drinking water, a treatment recently demonstrated to optimize brain plasticity in several pathological conditions, promotes motor recovery in rats that received a C4 dorsal funiculus crush. We show that fluoxetine administration markedly improved motor functions compared to controls in several behavioral paradigms. The improved functional effects correlated positively with significant sprouting of intact corticospinal fibers and a modulation of the excitation/inhibition balance. Our results suggest a potential application of fluoxetine treatment as a non invasive therapeutic strategy for SCI-associated neuropathologies. PMID:23860568

    With the progress of image-guided localization, body immobilization system, and computerized delivery of intensity-modulated radiation delivery, it became possible to perform spine radiosurgery. The next question is how to translate the high technology treatment to the clinical application. Clinical trials have been performed to demonstrate the feasibility of spine radiosurgery and efficacy of the treatment in the setting of spine metastasis, leading to the randomized trials by a cooperative group. Radiosurgery has also demonstrated its efficacy to decompress the spinal cord compression in selected group of patients. The experience indicates that spine radiosurgery has a potential to change the clinical practice in the management of spine metastasis and spinal cord compression. PMID:25874172

    We have tested the erectile effect of a topical applied drug (Minoxidil) in 15 spinal cord injured men. Minoxidil exerts a direct relaxant effect on arterial smooth muscles. This topical vasodilatory agent (1 ml of a 2% solution) was applied on the skin of the penile shaft. Increases in diameter and rigidity were measured with the RigiScan device (Dacomed Minneapolis, Minnesota). A total of 4 paraplegic men with a complete dorsal level lesion reported a positive erectile response. 3 of these 4 patients preferred to continue with this noninvasive treatment compared to prostaglandin E1 intracavernous injections. In our study no side effects were emerged and minoxidil proved to be well tolerated at the cutaneous level of the penis. Our results indicate that this treatment should be tested in spinal cord injured men before a invasive therapy is initiated. PMID:8303971

    To investigate the effects of probucol on the treatment of spinal cord injury in rat, 80 rats were randomly divided into two groups of 40: a group treated with probucol and a control group. Allen's method was used to establish a rat model of spinal cord injury. After establishment, probucol (500 mg·kg(-1)·day(-1)) was intraperitoneally injected into the treatment group rats for 1 week, while the same amount of saline was used to treat the control group. On days 1, 7, 14, 21, and 28 after treatment, the function of rats' spinal cord was evaluated according to the Bresnahan locomotor rating scale. Serum protein and mRNA levels of the cytokines [interferon (IFN)-γ, tumor necrosis factor (TNF)-α, and interleukin (IL)-17] were measured using enzyme-linked immunosorbent assay and quantitative polymerase chain reaction, respectively. Protein levels of IFN-γ, TNF-α, IL-17, and the downstream markers signal transducer and activator of transcription (STAT)-1 and STAT-3 were measured using western blot. In addition, the oxidative stress-related parameters, superoxide dismutase (SOD) and malondialdehyde (MDA), were also measured. It was found that compared to control group, rats from the treatment group had significantly lower levels of IFN-γ, TNF-α, and IL-17 (P < 0.05) on days 1 and 7, as well as lower MDA levels and higher SOD activity on days 7, 21, and 28 (P < 0.05). In summary, probucol improved the recovery of locomotion function after spinal cord injury in rats through downregulation of inflammation and upregulation of anti-oxidative activity. PMID:26214485

    The effect of delayed 2-amino-6-trifluoromethoxy-benzothiazole (riluzole) treatment on injured motoneurons was studied. The L4 ventral root of adult rats was avulsed and reimplanted into the spinal cord. Immediately after the operation or with a delay of 5, 10, 14 or 16 days animals were treated with riluzole (n=5 in each group) while another four animals remained untreated. Three months after the operation the fluorescent dye Fast Blue was applied to the proximal end of the cut ventral ramus of the L4 spinal nerve to retrogradely label reinnervating neurons. Three days later the spinal cords were processed for counting the retrogradely labeled cells and choline acetyltransferase immunohistochemistry was performed to reveal the cholinergic cells in the spinal cords. In untreated animals there were 20.4+/-1.6 (+/-S.E.M.) retrogradely labeled neurons while in animals treated with riluzole immediately or 5 and 10 days after ventral root avulsion the number of labeled motoneurons ranged between 763+/-36 and 815+/-50 (S.E.M.). Riluzole treatment starting at 14 and 16 days after injury resulted in significantly lower number of reinnervating motoneurons (67+/-4 and 52+/-3 S.E.M., respectively). Thus, riluzole dramatically enhanced the survival and reinnervating capacity of injured motoneurons not only when treatment started immediately after injury but also in cases when riluzole treatment was delayed for up to 10 days. These results suggest that motoneurons destined to die after ventral root avulsion are programmed to survive for some time after injury and riluzole is able to rescue them during this period of time.

    Stereotactic radiosurgery (SRS) is the accurate, conformal delivery of high-dose radiation to well-defined targets while minimizing normal structure doses via steep dose gradients. While inverse treatment planning (ITP) with computerized optimization algorithms are routine, many aspects of the planning process remain user-dependent. We performed an international, multi-institutional benchmark trial to study planning variability and to analyze preferable ITP practice for spinal robotic radiosurgery. 10 SRS treatment plans were generated for a complex-shaped spinal metastasis with 21 Gy in 3 fractions and tight constraints for spinal cord (V14Gy < 2 cc, V18Gy < 0.1 cc) and target (coverage > 95%). The resulting plans were rated on a scale from 1 to 4 (excellent-poor) in five categories (constraint compliance, optimization goals, low-dose regions, ITP complexity, and clinical acceptability) by a blinded review panel. Additionally, the plans were mathemati-cally rated based on plan indices (critical structure and target doses, conformity, monitor units, normal tissue complication probability, and treatment time) and compared to the human rankings. The treatment plans and the reviewers' rankings varied substantially among the participating centers. The average mean overall rank was 2.4 (1.2-4.0) and 8/10 plans were rated excellent in at least one category by at least one reviewer. The mathematical rankings agreed with the mean overall human rankings in 9/10 cases pointing toward the possibility for sole mathematical plan quality comparison. The final rankings revealed that a plan with a well-balanced trade-off among all planning objectives was preferred for treatment by most par-ticipants, reviewers, and the mathematical ranking system. Furthermore, this plan was generated with simple planning techniques. Our multi-institutional planning study found wide variability in ITP approaches for spinal robotic radiosurgery.

    Using a guinea pig model of lumbar myelopathy, various factors affecting the tolerance of spinal cord to irradiation were assessed: (a) extent of initial injury; (b) time interval between priming and test doses; and (c) animal age at the time of initial radiation treatment. A 3 cm section of lumbar spinal cord of guinea pigs was irradiated with fractionated doses of 4.5 Gy gamma rays given as 9 fractions per week. Guinea pigs were primed with 9 x 4.5 Gy in 7 days which is 60% of the ED[sub 50] for a continuous course of treatment. After 28 or 40 weeks, animal were retreated with 6-14 fractions of 4.5 Gy. Animals were observed for 2 years following the priming dose and both the incidence and latency of myelopathy recorded. Young adult guinea pigs (8 wk old) showed both a decreased radiation tolerance and latency compared to old individuals (40 wk old). At 28 or 40 wk after 9 x 4.5 Gy, only about 8% of the initial injury was remembered in young adult guinea pigs. The amount of residual injury was dependent on the initial damage as a proportion of the tolerance dose. The spinal cord shows a greater capacity for long-term recovery than generally appreciated and re-treatment doses clinically prescribed may be lower than necessary. 8 refs., 3 figs., 2 tabs.

    Background Minocycline, a second-generation tetracycline antibiotic, exhibits anti-inflammatory and neuroprotective effects in various experimental models of neurological diseases, such as stroke, Alzheimer’s disease, amyotrophic lateral sclerosis and spinal cord injury. However, conflicting results have prompted a debate regarding the beneficial effects of minocycline. Methods In this study, we analyzed minocycline treatment in organotypic spinal cord cultures of neonatal rats as a model of motor neuron survival and regeneration after injury. Minocycline was administered in 2 different concentrations (10 and 100 µM) at various time points in culture and fixed after 1 week. Results Prolonged minocycline administration decreased the survival of motor neurons in the organotypic cultures. This effect was strongly enhanced with higher concentrations of minocycline. High concentrations of minocycline reduced the number of DAPI-positive cell nuclei in organotypic cultures and simultaneously inhibited microglial activation. Astrocytes, which covered the surface of the control organotypic cultures, revealed a peripheral distribution after early minocycline treatment. Thus, we further analyzed the effects of 100 µM minocycline on the viability and migration ability of dispersed primary glial cell cultures. We found that minocycline reduced cell viability, delayed wound closure in a scratch migration assay and increased connexin 43 protein levels in these cultures. Conclusions The administration of high doses of minocycline was deleterious for motor neuron survival. In addition, it inhibited microglial activation and impaired glial viability and migration. These data suggest that especially high doses of minocycline might have undesired affects in treatment of spinal cord injury. Further experiments are required to determine the conditions for the safe clinical administration of minocycline in spinal cord injured patients. PMID:23967343

    Administration of the ovarian steroid estradiol in male and female animals has been shown to have neuromodulatory and neuroprotective effects in a variety of experimental models. In the present study, spinal tissues from dermatomes just above (T5–T7, at level) a severe chronic spinal cord injury (SCI) at T8 were analyzed for expression levels of prodynorphin (PRDN) and phospho-(serine 369) κ-opioid receptor (KOR-P) in 17 β estradiol (EB)- and placebo-treated adult male rats. Dynorphin was targeted since (1) it has previously been shown to be elevated post-SCI, (2) intrathecal injection of dynorphin produces several of the same adverse effects seen with a SCI, and (3) its increased expression is known to occur in a variety of different experimental models of central neuropathic pain. A significant elevation of extracellular levels of both PRDN and KOR-P in the placebo-treated SCI group relative to uninjured surgical sham controls was found in spinal tissues above the injury level, indicating increased dynorphin levels. Importantly, the EB-treated SCI group did not show elevations of PRDN levels at 6 weeks post-injury. Immunohistochemical analysis of at level tissues revealed that EB treatment significantly prevented a post-SCI increase in expression of PRDN puncta co-labeling synapsin I, a nerve terminal marker. The dynorphin-containing terminals co-labeled vesicular glutamate receptor-2 (a marker of glutamatergic terminals), a finding consistent with a non-opioid basis for the adverse effects of dynorphin. These results support a beneficial role for EB treatment post-SCI through a reduction in excessive spinal cord levels of dynorphin. Studies manipulating the timing of the EB treatment post-injury along with specific functional assessments will address whether the beneficial effects are due to EB’s potential neuromodulatory or neuroprotective action.

    Modern technologies allow the delivery of high radiation doses to intramedullary spinal cord metastases while lowering the dose to the neighboring organs at risk. Whether this dosimetric advantage translates into clinical benefit is not well known. This study evaluates the acute and late toxicity outcomes in a patient treated with robotic radiosurgery for an intramedullary spinal cord metastasis. A 50-year-old woman diagnosed in May 2006 with invasive ductal carcinoma of the right breast T2N3M1 (two liver metastases) received chemotherapy with a complete response. Subsequently, she underwent adjuvant whole-breast radiotherapy, along with tamoxifen. After several distant relapses, treated mainly with systemic therapy, the patient developed an intramedullary lesion at the C3-C4 level and was referred to our CyberKnife unit for assessment. A total dose of 14 Gy prescribed to the 74% isodose line was administered to the intramedullary lesion in one fraction. One hundred and two treatment beams were used covering 95.63% of the target volume. The mean dose was 15.93 Gy and the maximum dose, 18.92 Gy. Maximum dose to the spinal cord was 13.96 Gy, V12 ~ 0.13 cc and V8 ~ 0.43 cc. Three months after treatment, magnetic resonance imaging showed a reduction in size and enhancement of the intramedullary lesion with no associated toxicity. During this period, the patient showed a good performance status without neurological deficits. Currently, with a follow-up of 37 months, the patient has the ability to perform activities of daily life. Intramedullary spinal cord metastases is a rare and aggressive disease, often treatment-refractory. Our case demonstrates that radiation therapy delivery with robotic radiosurgery allows the achievement of a high local control without adding toxicity. PMID:27330877

    The physiological assessment of highly-trained athletes is a cornerstone of many scientific support programs. In the present article, we provide original data followed by our perspective on the topic of laboratory-based incremental exercise testing in elite athletes with cervical spinal cord injury. We retrospectively reviewed our data on Great Britain Wheelchair Rugby athletes collected during the last two Paralympic cycles. We extracted and compared peak cardiometabolic (heart rate and blood lactate) responses between a standard laboratory-based incremental exercise test on a treadmill and two different maximal field tests (4 min and 40 min maximal push). In the nine athletes studied, both field tests elicited higher peak responses than the laboratory-based test. The present data imply that laboratory-based incremental protocols preclude the attainment of true peak cardiometabolic responses. This may be due to the different locomotor patterns required to sustain wheelchair propulsion during treadmill exercise or that maximal incremental treadmill protocols only require individuals to exercise at or near maximal exhaustion for a relatively short period of time. We acknowledge that both field- and laboratory-based testing have respective merits and pitfalls and suggest that the choice of test be dictated by the question at hand: if true peak responses are required then field-based testing is warranted, whereas laboratory-based testing may be more appropriate for obtaining cardiometabolic responses across a range of standardized exercise intensities.

  13. Diagnosis and Treatment of Bone Disease in Multiple Myeloma: Spotlight on Spinal Involvement

    PubMed Central

    Tosi, Patrizia

    2013-01-01

    Bone disease is observed in almost 80% of newly diagnosed symptomatic multiple myeloma patients, and spine is the bone site that is more frequently affected by myeloma-induced osteoporosis, osteolyses, or compression fractures. In almost 20% of the cases, spinal cord compression may occur; diagnosis and treatment must be carried out rapidly in order to avoid a permanent sensitive or motor defect. Although whole body skeletal X-ray is considered mandatory for multiple myeloma staging, magnetic resonance imaging is presently considered the most appropriate diagnostic technique for the evaluation of vertebral alterations, as it allows to detect not only the exact morphology of the lesions, but also the pattern of bone marrow infiltration by the disease. Multiple treatment modalities can be used to manage multiple myeloma-related vertebral lesions. Surgery or radiotherapy is mainly employed in case of spinal cord compression, impending fractures, or intractable pain. Percutaneous vertebroplasty or balloon kyphoplasty can reduce local pain in a significant fraction of treated patients, without interfering with subsequent therapeutic programs. Systemic antimyeloma therapy with conventional chemotherapy or, more appropriately, with combinations of conventional chemotherapy and compounds acting on both neoplastic plasma cells and bone marrow microenvironment must be soon initiated in order to reduce bone resorption and, possibly, promote bone formation. Bisphosphonates should also be used in combination with antimyeloma therapy as they reduce bone resorption and prolong patients survival. A multidisciplinary approach is thus needed in order to properly manage spinal involvement in multiple myeloma. PMID:24381787

Methods: We identified patients with traumatic spinal cord injury for whom consent and detailed data were available from among patients recruited (2004–2013) at any of the 31 acute care and rehabilitation hospitals participating in the Rick Hansen Spinal Cord Injury Registry. Patients were assessed by age group (< 70 v. ≥ 70 yr). The primary outcome was the rate of acute surgical treatment. We used bivariate and multivariate regression models to assess patient and injury-related factors associated with receiving surgical treatment and with the timing of surgery after arrival to a participating centre. Results: Of the 1440 patients included in our study cohort, 167 (11.6%) were 70 years or older at the time of injury. Older patients were more likely than younger patients to be injured by falling (83.1% v. 37.4%; p < 0.001), to have a cervical injury (78.0% v. 61.6%; p = 0.001), to have less severe injuries on admission (American Spinal Injury Association Impairment Scale grade C or D: 70.5% v. 46.9%; p < 0.001), to have a longer stay in an acute care hospital (median 35 v. 28 d; p < 0.005) and to have a higher in-hospital mortality (4.2% v. 0.6%; p < 0.001). Multivariate analysis did not show that age of 70 years or more at injury was associated with a decreased likelihood of surgical treatment (adjusted odds ratio [OR] 0.48, 95% confidence interval [CI] 0.22–1.07). An unplanned sensitivity analysis with different age thresholds showed that a threshold of 65 years was associated with a decreased chance of surgical treatment (OR 0.39, 95% CI 0.19–0.80). Older patients who underwent surgical treatment had a significantly longer wait time from admission to surgery than younger patients (37 v. 19 h; p < 0.001). Interpretation: We found chronological age to be a factor influencing

    Based on previous experimental investigations which indicated that low-power laser irradiation has a significant therapeutic effect and treatment potential on the injured nerve tissue, the authors began using this method in clinical practice. This data represents the first clinical results in the treatment of four patients with tethered spinal cord resulting from fibrous adhesions at the site of previous myelomeningocele and lypomyelomeningocele repair, thickened filum terminale and spinal lipoma. After surgical release of the tethered spinal cord, stable evoked responses were recorded and the conus medullaris was subjected to direct laser irradiation (CW He-Ne laser, 632.8nm, 7Jcm2). The findings show intraoperative laser treatment increases evoked responses from 15-52% (mean 26.7%). In a previous work, it was shown that direct laser irradiation promotes restoration of the electrophysiological activity of the severely injured peripheral nerve, prevents degenerative changes in neurons of the spinal cord and induces proliferation of astrocytes and oligodendrocytes. This suggested a higher metabolism in neurons and improved ability for myelin production under the influence of laser treatment. It is well known that tethering of the spinal cord causes mechanical damage to neuronal cell membranes leading to metabolic disturbances in the neurons. For this reason, the authors believe that using low-power laser irradiation may improve neuronal metabolism, prevent neuronal degeneration and promote improved spinal cord function and repair.

    OBJECTIVES: To evaluate the effects of monosialoganglioside (GM1) administered transdermally with laser in the recovery of spinal cord injury in rats. METHODS: Forty male Wistar rats underwent spinal cord contusion using the NYU Impactor. In Group 1, the rats received 0,2 ml of saline intraperitoneally daily; in Group 2, GM1 was administered intraperitoneally at a concentration of 30 mg/kg per day; in Group 3, rats were treated daily with laser at low temperature on the skin, and in Group 4, the daily laser session also contained GM1. All the groups were treated for 42 days. The animals were evaluated by the Basso, Baettie and Bresnahan (BBB) functional scale on days 7, 14, 21, 28, 35 and 42 after the injury, and by histopathology and motor evoked potential after 42 days of injury. RESULTS: The animals in Group 4 had higher BBB scores compared with the other groups. There were no differences between the groups, or in the comparisons over time. Histological evaluation showed no differences, and no differences were found in the motor evoked potential tests either. CONCLUSION: GM1 associated with the use of low-temperature laser shows no superior functional, neurological or histological results in the treatment of spinal cord lesions in rats.

    We performed a double-blinded, randomized, controlled trial in 15 patients to determine the efficacy of intrathecal morphine or clonidine, alone or combined, in the treatment of neuropathic pain after spinal cord injury. The combination of morphine and clonidine produced significantly more pain relief than placebo 4 h after administration; either morphine or clonidine alone did not produce as much pain relief. In addition, lumbar and cervical cerebrospinal fluid (CSF) concentrations, sampled at these levels at different times after administration were examined for a relationship between pain relief and CSF drug concentration. Lumbar CSF drug concentrations were initially several orders of magnitude larger than those in cervical CSF. After 1-2 h, the concentrations of morphine in cervical CSF markedly exceeded those of clonidine. The concentration of morphine in the cervical CSF and the degree of pain relief correlated significantly. We conclude that intrathecal administration of a mixture of clonidine and morphine is more effective than either drug administered alone and is related to the CSF-borne drug concentration above the level of spinal cord injury. If there is pathology that may restrict CSF flow, consideration should be given to intrathecal administration above the level of spinal cord damage to provide an adequate drug concentration in this region.

    Poly(3, 4-ethylenedioxythiophene)-coated carbon microfibers (PEDOT-MFs) hold promise for developing advanced neuroprostheses and neural repair devices. We investigated the chronic cellular responses to PEDOT-MFs implanted into the uninjured and the transected rat spinal cord, and compared the effects of polymer surface biofunctionalization with covalently attached polylysine (PLL) or a multimolecular complex of PLL, heparin, basic fibroblast growth factor (bFGF), and fibronectin. An alginate gel was used to facilitate microfiber implantation and reduce connective tissue scarring after spinal cord injury (SCI). PLL/heparin/bFGF/fibronectin-functionalized PEDOT-MFs showed excellent integration within the uninjured and injured spinal cord, frequently establishing contact with neuronal somas, axons, dendrites and glial cells, accompanied by very little or absent scarring response. On the contrary, non-functionalized and PLL-functionalized microfibers provoked inflammation and fibrosis with loss of neural elements in the surrounding tissue. Within the lesion, the PEDOT-MFs by themselves facilitated longitudinal alignment of migratory cells and growing axons, and their modification with PLL/heparin/bFGF/fibronectin promoted tissue healing, enhancing blood vessel formation and axonal regeneration without increasing inflammation. These results support the incorporation of biofunctionalized electroconducting microfibers in neuro-electronic interfaces and lesion-bridging systems for the treatment of SCI. PMID:26963900

    Malignant spinal cord compression (MSCC) is a common complication of cancer. Paraspinal neuroblastoma (NB) in the thoracic, abdominal and pelvic regions may extend into the neural foramina causing compression of nerve roots and even the spinal cord. The prompt initiation of specific treatment can improve the neurological outcome. The aim of the present study was to review the clinical features, the management received and the factors that may affect the outcome of patients with MSCC caused by paraspinal NB. During a period between July 2007 and December 2012, a total of 576 NB patients were treated at the Children’s Cancer Hospital (Cairo, Egypt). Intraspinal disease extension was present in 51 patients (9%). The children with intraspinal disease extension were reviewed for disease pattern, neurological manifestations and treatment outcome. Children with intraspinal disease extension had an equal male to female ratio (1:1), and approximately two-thirds of patients (34/51) had a clinically manifested cord compression. The duration of neurological manifestations was >4 weeks in 58.8% (20/34) of symptomatic patients and ≤4 weeks in 41.2% (14/34). Subsequent to starting treatment, neurological manifestations showed a complete recovery in 16 patients (47.1%), partial in 11 (32.4%), and stationary course was found in 7 (20.6%). Manifestations of ≤4 weeks in duration carried an improved outcome compared with longer time compression, with a complete recovery in 78.6%, versus 25% for patients with a longer symptom duration (P=0.008). The upfront treatment, patient age and site of the primary tumor did not significantly affect the neurological outcome. Spinal cord compression in NB can be effectively managed with upfront chemotherapy. Initial surgical decompression should be reserved for benign variants only, including ganglioneuroma. Neurological manifestations of <4 weeks duration upon presentation are usually reversible. PMID:25624912

    Objective. Spinal cord injury (SCI) is a devastating neurological disorder caused by trauma. Pathophysiological events occurring after SCI include acute, subacute, and chronic phases, while complex mechanisms are comprised. As an abundant source of natural drugs, Traditional Chinese Medicine (TCM) attracts much attention in SCI treatment recently. Hence, this review provides an overview of pathophysiology of SCI and TCM application in its therapy. Methods. Information was collected from articles published in peer-reviewed journals via electronic search (PubMed, SciFinder, Google Scholar, Web of Science, and CNKI), as well as from master's dissertations, doctoral dissertations, and Chinese Pharmacopoeia. Results. Both active ingredients and herbs could exert prevention and treatment against SCI, which is linked to antioxidant, anti-inflammatory, neuroprotective, or antiapoptosis effects. The detailed information of six active natural ingredients (i.e., curcumin, resveratrol, epigallocatechin gallate, ligustrazine, quercitrin, and puerarin) and five commonly used herbs (i.e., Danshen, Ginkgo, Ginseng, Notoginseng, and Astragali Radix) was elucidated and summarized. Conclusions. As an important supplementary treatment, TCM may provide benefits in repair of injured spinal cord. With a general consensus that future clinical approaches will be diversified and a combination of multiple strategies, TCM is likely to attract greater attention in SCI treatment. PMID:27118982

    Intramedullary spinal cord tumors have low incidence rates but are associated with difficult treatment options. The majority of patients with these tumors can be initially treated with an attempted resection. Unfortunately, those patients who cannot undergo gross-total resection or have subtotal resection are left with few treatment options, such as radiotherapy and chemotherapy. These adjuvant treatments, however, are associated with the potential for significant adverse side effects and still leave patients with a poor prognosis. To successfully manage these patients and improve both their quality of life and prognosis, novel treatment options must be developed to supplement subtotal resection. New research is underway investigating alternative therapeutic approaches for these patients, including directed, localized drug delivery and nanomedicine techniques. These and other future investigations will hopefully lead to promising new therapies for these devastating diseases. PMID:26235012

    patients were treated by posterior approach surgery and combined anterior and posterior approach surgery was performed in a single sitting on 28 patients. Results: All patients were followed for 0.5-18 years (mean 11.8 years). At least one Frankel grade improvement was observed in 178 (60.3%) patients. In the anterior surgery group, the best results were observed in the cases with slight compressive fracture with disc herniation (44/50 patients, 88.0%). In the posterior surgery group, one Frankel grade improvement was observed in the cases with developmental spinal canal stenosis with trauma, lamina fractures, ligament injuries and hematoma (27/31, 87.1%). Most of the patients in the Frankel D group recovered normal neurological function after surgery. The majority of the patients with Frankel C neurological deficit (102/124) had the ability to walk postoperatively, while most of the seriously injured patients (Frankel A and B) had no improvement in their neurological function. Radiolographic fusion of the operated segments occurred in most patients within three months. Loss of intervertebral height and cervical physiological curvature was observed to varying degrees in 30.1% (71/236) of the cases in the anterior surgery group. Conclusion: First aid measures of early closed reduction or realignment and immobilization of the cervical spine, breathing support and high-dose methylprednisolone were most important in the treatment for traumatic spinal cord injury. Surgery should be performed as soon as the indications of spinal injury appear. The choice of the approach—anterior, posterior or both, should be based on the type of the injury and the surgeon's experience. Any complications should be actively prevented and treated.

    A randomized clinical trial of 15 patients with acute spinal cord injuries was performed to test the hypothesis that rotating treatment tables prevent deep venous thrombosis in this population. Four of 5 control (nonrotated) patients developed distal and proximal thrombi, assessed by /sup 125/I fibrinogen leg scans and impedance plethysmography. In comparison, only 1 of 10 treated (rotated) patients developed both distal and proximal thrombosis. These results suggest but do not prove that rotating treatment tables prevent the development of proximal deep venous thrombosis in spinal cord-injured patients. Larger clinical trials are needed to confirm this heretofore undocumented benefit of rotating treatment tables.

    Assessment of improved treatment of neurotrauma presents two basic challenges: 1) measurement of the medical effects of treatment, and 2) evaluation of these effects in socioeconomic terms. A nationwide survey was conducted in 1988 to estimate the prevalence of persons in the United States who suffered traumatic spinal cord injury and to calculate its economic consequences. Seven hundred fifty-eight persons weighted to be representative of the spinal cord injury population were interviewed. The prevalence rate was found to be 721 cases per million people. Conservative calculations for 1988 showed that the average direct costs per person were $103,000 for hospitalization and home modifications during the first 2 years postinjury and $14,000 per year thereafter for medical care. Losses in earnings and homemaker services averaged $12,726 per year. Total aggregate costs for 1 year were estimated at $5.6 billion. Lifetime costs for a representative person with complete paraplegia injured at age 33 were estimated to be $500,000. For a representative person with complete quadriplegia injured at age 27, these costs amounted to $1 million. These data can be used to estimate cost savings related to decreased disability resulting from improved treatment. PMID:8445206

    Spinal deformity is a relatively common disorder, particularly in teenage girls. Early detection is possible by a simple, quick visual inspection that should be a standard part of the routine examination of all preteen and teenage patients. Follow-up observation will reveal those curvatures that are progressive and permit orthotic treatment to prevent further increase in the deformity. Spinal fusion offers correction and stabilization of more severe degrees of scoliosis. PMID:3786010

    This retrospective cohort study was conducted to evaluate the clinical outcomes of radical anterolateral debridement and autogenous ilium with rib or titanium cage interbody autografting with transpedicle fixation for the treatment of thoracolumbar tuberculosis. Spinal tuberculosis operation aims to remove the lesions and necrotic tissues, remove spinal cord compression, and reconstruct spinal stability. However, traditional operation methods cannot effectively correct cyrtosis or stabilize the spine. In addition, the patient needs to stay in bed for a long time and may have many complications. So far, the best surgical method and fixation method for spinal tuberculosis remain controversial. There were a total of 43 patients, 16 involving spinal cord injury, from January 2004 to January 2011. The patients were surgically treated for radical anterolateral debridement via posterolateral incision and autogenous ilium with rib or titanium cage interbody autografting and single-stage transpedicle fixation. All the patients were followed up to determine the stages of intervertebral bone fusion and the corrections of spinal kyphosis with the restoration of neurological deficit. The erythrocyte sedimentation rate (ESR) of these patients decreased to normal levels for a mean of 2.8 months. The function of feeling, motion, and sphincter in 16 paraplegia cases gradually recovered after 1 week to 3 months postoperatively, and the American Spinal Injury Association scores significantly increased at the final follow-up. Intervertebral bone fusions were all achieved postoperatively. No internal fixation devices were loose, extracted, or broken. There was no correction degree loss during the follow-up. The method of radical anterolateral debridement and autogenous ilium with rib or titanium cage interbody autografting and single-stage transpedicle fixation was effective for the treatment of thoracolumbar tuberculosis, correcting kyphotic deformity, and reconstructing spinal

    Objective To investigate the effects of early tamsulosin treatment on changes in bladder characteristics after a spinal cord injury. Methods We divided 45 rats into three groups: the control (CON) group, the spinal cord injury (SCI) group, and the SCI+tamsulosin treatment (SCI+TAM) group. Spinal cord transection was performed in the SCI and SCI+TAM groups. Tamsulosin was injected for 7 days in the SCI+TAM group. Intravesical and intra-abdominal catheters were implanted before cord injury. Basal pressure (BP), maximal vesical pressure (MVP), micturition volume (MV), and voiding interval time (VIT) were measured at 7 days after SCI. The bladder was then removed and used for an in vitro organ bath study and Western blot analysis. The percentage changes in contractility from baseline after acetylcholine alone, pretreatment with a muscarinic 2 (M2) receptor blocker (AQ-RA741), and pretreatment with a M3 receptor blocker (4-DAMP) were compared among the groups. Western blot analyses were performed to determine expression levels of pERK1/2 and rho-kinase. Results In cystometry, MVP, BP, MV, and VIT showed changes in the SCI and SCI+TAM groups versus the CON group (p<0.05). In the organ bath study, acetylcholine-induced contractility in the three groups differed significantly (p<0.05). Additionally, acetylcholine-induced contractility with 4-DAMP pretreatment was reduced significantly in the SCI+TAM group versus the SCI group. In Western blotting, pERK1/2 expression was stronger (p<0.05) and rho-kinase expression was weaker in the SCI+TAM group than the SCI group (p<0.05). Conclusion These results suggest that the bladder contraction due to acetylcholine after SCI can be decreased by tamsulosin in the acute stage and this involves changes in pERK1/2 and rho-kinase.

    2012-01-01

    Cervical radiculopathy (CR), while less common than conditions with neck pain alone, can be a significant cause of neck pain and disability; thus the determination of adequate treatment options for patients is essential. Currently, inadequate scientific literature restricts specific conservative management recommendations for CR. Despite a paucity of evidence for high-velocity low-amplitude (HVLA) spinal manipulation in the treatment for CR, this strategy has been frequently labeled as contraindicated. Scientific support for appropriate outcome measures for CR is equally deficient. While more scientific data is needed to draw firm conclusions, the present review suggests that spinal manipulation may be cautiously considered as a therapeutic option for patients suffering from CR. With respect to outcome measures, the Neck Disability Index appears well-suited for spinal manipulative treatment of CR. PMID:22457538

    Background Low back pain has major health and social implications. Although there have been many randomised controlled trials of manipulation and exercise for the management of low back pain, the role of these two treatments in its routine management remains unclear. A previous trial comparing private chiropractic treatment with National Health Service (NHS) outpatient treatment, which found a benefit from chiropractic treatment, has been criticised because it did not take treatment location into account. There are data to suggest that general exercise programmes may have beneficial effects on low back pain. The UK Medical Research Council (MRC) has funded this major trial of physical treatments for back pain, based in primary care. It aims to establish if, when added to best care in general practice, a defined package of spinal manipulation and a defined programme of exercise classes (Back to Fitness) improve participant-assessed outcomes. Additionally the trial compares outcomes between participants receiving the spinal manipulation in NHS premises and in private premises. Design Randomised controlled trial using a 3 × 2 factorial design. Methods We sought to randomise 1350 participants with simple low back pain of at least one month's duration. These came from 14 locations across the UK, each with a cluster of 10–15 general practices that were members of the MRC General Practice Research Framework (GPRF). All practices were trained in the active management of low back pain. Participants were randomised to this form of general practice care only, or this general practice care plus manipulation, or this general practice care plus exercise, or this general practice care plus manipulation followed by exercise. Those randomised to manipulation were further randomised to receive treatment in either NHS or private premises. Follow up was by postal questionnaire one, three and 12 months after randomisation. The primary analysis will consider the main treatment

    Oncological treatments can lead to acute and chronic cancer related toxicities. In recent years, a large number of clinical studies have reported positive effects of exercise to the bio-psycho-social regeneration of cancer patients. However, very few evidence-based programs have been implemented into practice with little opportunity for cancer patients to engage in such programs. Reviews and RCT studies on exercise and cancer are showing that specific exercise programs have a positive impact on fatigue syndrome, urinary incontinence, lymphedema, polyneuropathy, arthralgia, and androgen deprivation related toxicities. With the increasing evidence for exercise oncology interventions, recommendations arising from clinical trials should be translated into clinical practice and this should be viewed as an important next step in this fast moving field of exercise oncology. For that the personalized treatment concept "Oncologic clinical exercise" (OTT) was developed. PMID:26402184

  18. Sustained release of estrogens from PEGylated nanoparticles for treatment of secondary spinal cord injury

    NASA Astrophysics Data System (ADS)

    Barry, John

    Spinal Cord Injury (SCI) is a debilitating condition which causes neurological damage and can result in paralysis. SCI results in immediate mechanical damage to the spinal cord, but secondary injuries due to inflammation, oxidative damage, and activated biochemical pathways leading to apoptosis exacerbate the injury. The only currently available treatment, methylprednisolone, is controversial because there is no convincing data to support its therapeutic efficacy for SCI treatment. In the absence of an effective SCI treatment option, 17beta-estradiol has gained significant attention for its anti-oxidant, anti-inflammatory, and anti-apoptotic abilities, all events associated with secondary. Sadly, 17beta-estradiol is associated with systemic adverse effects preclude the use of free estrogen even for local administration due to short drug half-life in the body. Biodegradable nanoparticles can be used to increase half-life after local administration and to bestow sustained release. Sustained release using PEGylated biodegradable polymeric nanoparticles constructed from poly(lactic-co-glycolic acid) (PLGA) will endow a consistent, low, but effective dose to be delivered locally. This will limit systemic effects due to local administration and low dose, sustained release. PLGA was chosen because it has been used extensively for sustained release, and has a record of safety in humans. Here, we show the in vitro efficacy of PEGylated nanoparticles loaded with 17beta-estradiol for treatment of secondary SCI. We achieved a high loading efficiency and controlled release from the particles over a several day therapeutic window. The particles also show neuroprotection in two in vitro cell culture models. Both the dose and pretreatment time with nanoparticles was evaluated in an effort to translate the treatment into an animal model for further study.

    Context Over the last four decades, the focus of spinal cord injury (SCI) rehabilitation has shifted from medical management to issues that affect quality of life and community participation. Physical therapists (PTs) need to design and implement interventions that result in maximal participation to provide an individual with SCI an effective rehabilitation program. Objective The aim of this review is to assess the extent, content, and outcomes of physical therapy (PT) interventions focused on improving the participation of individuals with SCI. Methods A search was conducted in Medline, Embase, CENTRAL, CINAHL, PEDro, and PsycINFO. We included studies, of all designs, focused on improving the participation of individuals with SCI using PT interventions.The primary author and a reviewer independently selected articles for inclusion, assessed articles quality, and extracted the data. Results Five studies met the inclusion criteria. The interventions applied were 9- and 12-month body weight-supported treadmill training in two studies, a supervised 9-month exercise program, a 12-week home exercise program, and a 10-week multidisciplinary cognitive behavioral program for coping with chronic neuropathic pain. Four of five PT interventions positively impacted the individual's perceived participation and satisfaction with participation. Conclusion The body of research by PTs on interventions to improve participation is limited. PTs must document the effects of interventions with a valid outcome tool to enable more research that examines participation. Expanding participation research will allow PTs to meet the needs of individuals with SCI and identify what interventions best facilitate integration into the community. PMID:24621042

    Abstract Surgical intervention is an important option for treating spinal tuberculosis. Previous studies have reported different surgical procedures and bone grafts for it. To our knowledge, few studies demonstrated the clinical results of using nonstructural autogenous bone graft in surgical treatment of spinal tuberculosis. The purpose of this study is to compare the clinical outcomes of surgical management lumbar spinal tuberculosis by one-stage posterior debridement with nonstructural autogenous bone grafting and instrumentation versus anterior debridement, strut bone grafting combined with posterior instrumentation. A total of 58 consecutive patients who underwent surgical treatment due to lumbar spinal tuberculosis from January 2011 to December 2013 were included. A total of 22 patients underwent one-stage posterior debridement, nonstructural autogenous bone grafting, and instrumentation (group A), and 36 patients received anterior debridement, strut bone grafting combined with posterior instrumentation (group B). The operative duration, total blood loss, perioperative transfusion, length of hospital stay, hospitalization cost, and complications were recorded. The bony fusion of the graft was assessed by computed tomography scans. American Spinal Injury Association (ASIA) Impairment Scale was used to evaluate the neurological function of patients in the 2 groups. All the patients were followed up, with a mean follow-up duration of 21.6 ± 5.7 months in group A and 22.3 ± 6.2 months in group B (P = 0.47). The average operative duration was 257.5 ± 91.1 minutes in group A and 335.7 ± 91.0 minutes in group B (P = 0.002). The mean total blood loss was 769.6 ± 150.9 mL in group A and 1048.6 ± 556.9 mL in group B (P = 0.007). Also, significant differences were found between the 2 groups in perioperative transfusion volumes, length of hospital stay, and hospitalization cost (P < 0.05), which were less in group A

    The neural degeneration caused by spinal cord injury leaves a cavity at the injury site that greatly inhibits repair. One approach to promoting repair is to fill the cavity with a scaffold to limit further damage and encourage regrowth. Injectable materials are advantageous scaffolds because they can be placed as a liquid in the lesion site then form a solid in vivo that precisely matches the contours of the lesion. Fibrin is one type of injectable scaffold, but risk of infection from blood borne pathogens has limited its use. We investigated the potential utility of salmon fibrin as an injectable scaffold to treat spinal cord injury since it lacks mammalian infectious agents and encourages greater neuronal extension in vitro than mammalian fibrin or Matrigel®, another injectable material. Female rats received a T9 dorsal hemisection injury and were treated with either salmon or human fibrin at the time of injury while a third group served as untreated controls. Locomotor function was assessed using the BBB scale, bladder function was analyzed by measuring residual urine, and sensory responses were tested by mechanical stimulation (von Frey hairs). Histological analyses quantified the glial scar, lesion volume, and serotonergic fiber density. Rats that received salmon fibrin exhibited significantly improved recovery of both locomotor and bladder function and a greater density of serotonergic innervation caudal to the lesion site without exacerbation of pain. Rats treated with salmon fibrin also exhibited less autophagia than those treated with human fibrin, potentially pointing to amelioration of sensory dysfunction. Glial scar formation and lesion size did not differ significantly among groups. The pattern and timing of salmon fibrin's effects suggest that it acts on neuronal populations but not by stimulating long tract regeneration. Salmon fibrin clearly has properties distinct from those of mammalian fibrin and is a beneficial injectable scaffold for treatment

    The authors describe the case of a 6.6-cm symptomatic spinal aneurysmal bone cyst (ABC) in a 17-year-old athlete treated percutaneously. Surgical treatment was not considered as the first option owing to its invasiveness and associated morbidity. CT-guided cryoablation of the expansile part of the ABC was performed for tumour shrinkage and nerve decompression. Thermal insulation, temperature monitoring and functional control/electrostimulation of the neural structures at risk were applied. Finally, the bony defect was cemented. No complications occurred during the procedure. Complete resolution of the ABC on imaging and clinical improvement were achieved. Percutaneous cryoablation should be considered as an alternative treatment option, especially when tumour size reduction is desired. PMID:25091121

    Effective treatment of Major Depressive Disorder (MDD) will require the development of alternative treatments and the ability for clinicians to match patients with the treatment likely to produce the greatest effect. We examined atypical depression subtype as a predictor of treatment response to aerobic exercise augmentation in persons with non-remitted MDD. Our results revealed a small-to-moderate effect, particularly in a group assigned to high-dose exercise (semi-partial eta-squared =0.0335, p=0.0735), indicating that those with atypical depression tended to have larger treatment response to exercise. Through this hypothesis-generating analysis, we indicate the need for research to examine depression subtype, along with other demographic, clinical and biological factors as predictors of treatment response to exercise.

    Physical activity potentially encourages a healthy lifestyle and it could have a more direct preventive effect on certain forms of carcinogenesis (for instance, by speeding gastrointestinal transit, or by moderating sex hormone levels). However, there are also potential negative effects, particularly an excessive exposure to ultraviolet light in certain water sports. The many types of neoplasm and the equally varied sources of physical activity militate against finding any simple relationship between the risk of malignancy and the individual's physical activity history. Nevertheless, evidence that physical activity protects against certain forms of cancer can be deduced from studies of experimental animals, former athletes, people employed in active occupations, and those with an active recreational lifestyle. Many occupational surveys and a number of studies of recreational activity show an association between sedentary living and a risk of colon cancer, both in men and in women. Moreover, an application of Bradford Hill's criteria gives some support to the causal nature of the association. More limited data suggest that a history of active leisure is associated with a reduced risk of all-cause cancer and in women of breast and reproductive system cancers. The last observation must still be reconciled with an apparent increase in the risk of prostatic cancer in active men. Since moderate exercise elevates mood and helps to conserve lean tissue, it may finally be a helpful component of treatment after a neoplasm has been diagnosed. PMID:8460289

    Background Few studies have assessed whether treatment of acute cervical spinal cord injury (SCI) patients contributes to depression. Methods Using an administrative database, we assessed patients for whom the diagnosis was unspecified injuries of cervical spinal cord (International Classification of Diseases and Injuries-10th (ICD-10) code; S14.1). We categorized patients with codes for depressive episode (ICD-10 code; F32) or recurrent depressive disorder (F33), or those prescribed antidepressants (tricyclic, tetracyclic, Selective Serotonin Reuptake Inhibitors, Serotonin Noradrenaline Reuptake Inhibitors, Trazodone, Sulpiride, or Mirtazapine) as having a depressive state. We compared the rate of each acute treatment between the depressive state group and the non-depressive state group using chi-square tests, and a multiple logistic regression model was used to identify the association between the acute treatment and depressive state. Results There were 151 patients who were judged to be in a depressive state, and the other 2115 patients were categorized into the non-depressive state group. Intervention of intravenous anesthesia, tracheostomy, artificial respiration, and gastrostomy had a significant positive correlation with depressive state. Multiple logistic regression analysis showed that tracheostomy (odds ratio [OR] 2.18; 95% confidence interval [CI], 1.09–4.38) and artificial respiration (OR 2.28; 95% CI, 1.32–3.93) were significantly associated with depressive state, and men had a 36% reduction in the risk of depressive state compared with women (OR 0.64; 95% CI, 0.44–0.94), whereas age, wound-treatment, all of the orthopedic procedures, intravenous anesthesia, and gastrostomy were not associated with depressive state. Conclusions These findings suggest that tracheostomy, artificial respiration and female gender in the acute phase after cervical SCI might be associated with the development of depression.

    Advances made in recent times in spinal cord injury repair research will soon take us toward a cure in paraplegics. But what are the prospects for quadriplegics? Certain fundamental issues make treatment approaches to quadriplegia different and difficult. Injury at cervical region poses additional problems for any surgical intervention with life-threatening risks of i) endangering respiratory function, ii) cavitation, cysts, and syringomyelia formation extending cephalad to the injury, and iii) mid-lower cervical injuries, lower motor neuron death, and the resultant degeneration of brachial plexus axons would still leave the upper limbs denervated and paralyzed even as treatment procedures might successfully salvage the lower limbs. With these apparently insurmountable impediments in quadriplegic cord repair, it would be wise to turn to alternative treatment strategies. Conventional treatment models since the days of Ralph Gerard (1940) have all used intra-vertebral procedures. We present here a plausible extra-vertebral repair model suitable for incomplete cord injuries at cervical, thoracic, and lumbar levels. The procedure consists of identifying the extent of viable grey-white matter in the injured area and to utilize it efficiently as a "neural tissue bridge." Next, labile state is induced by using botulinum toxin/colchicine (Krishnan, 1983, 1991; Krishnan et al., 2001 a,b) and Ca+ channel blockers in the motorsensory nerve terminals of polisegmentally innervated skeletal muscles that "bridge" the injured cord segments. This would retrogradely induce a redundant state of intra-spinal growth of nerve terminals and new synaptic connections within those viable neural tissues, as well as promote effective relinking of the injured cord ends and enhance motor-sensory recovery.

    Study Strategy A retrospective clinic study. Purpose To evaluate the efficacy of conservative and surgical treatment for lumbosacral tuberculosis. Methods This study retrospectively reviewed 53 patients with lumbosacral tuberculosis who were treated in our institution between January 2005 and January 2011. There were 29 males and 24 females with average ages of 37.53 ± 17.28 years (range 6–72 years). 11 patients were given only anti-TB drugs; the remainder underwent anterior debridement, interbody fusion with and without instrumentation, or one-stage anterior debridement combined with posterior instrumentation. Outcome data for these patients included neurologic status, lumbosacral angle, erythrocyte sedimentation rate value(ESR) and C-reactive protein value(CRP) were assessed before and after treatment. Results The mean lumbosacral angles were 23.00°± 2.90°in the conservatively treated patients and 22.36°± 3.92o in the surgically treated patients. At the final follow-up, this had improved to 24.10o ± 2.96°in the conservatively treated patients and 28.13° ± 1.93°in the surgically treated patients (all P < 0.05). There were statistically significant differences before and after treatment in terms of ESR and CRP (all P < 0.05). All patients achieved bone fusion. The mean follow-up period was 32.34 ± 8.13 months (range 18 to 55 months). The neurological deficit did not worsen in any of the patients. Conclusions It has been proven that conservative and surgical treatments are safe and effective and produce good clinical outcomes for patients with lumbosacral tuberculosis. The advantages of operation include thoroughness of debridement, decompression of the spinal cord, and adequate spinal stabilization. PMID:26121685

    2016-01-01

    Background Physical exercise effectively attenuates neuropathic pain, and multiple events including the inhibition of activated glial cells in the spinal dorsal horn, activation of the descending pain inhibitory system, and reductions in pro-inflammatory cytokines in injured peripheral nerves may contribute to exercise-induced hypoalgesia. Since fewer GABAergic hypoalgesic interneurons exist in the dorsal horn in neuropathic pain model animals, the recovery of impaired GABAergic inhibition in the dorsal horn may improve pain behavior. We herein determined whether the production of gamma-aminobutyric acid (GABA) and glutamic acid decarboxylase (GAD) in the dorsal horn is restored by treadmill running and contributes to exercise-induced hypoalgesia in neuropathic pain model mice. C57BL/6 J mice underwent partial sciatic nerve ligation (PSL). PSL-Runner mice ran on a treadmill at 7 m/min for 60 min/day, 5 days/week, from two days after PSL. Results Mechanical allodynia and heat hyperalgesia developed in PSL-Sedentary mice but were significantly attenuated in PSL-Runner mice. PSL markedly decreased GABA and GAD65/67 levels in neuropils in the ipsilateral dorsal horn, while treadmill running inhibited these reductions. GABA+ neuronal nuclei+ interneuron numbers in the ipsilateral dorsal horn were significantly decreased in PSL-Sedentary mice but not in PSL-Runner mice. Pain behavior thresholds positively correlated with GABA and GAD65/67 levels and GABAergic interneuron numbers in the ipsilateral dorsal horns of PSL-Sedentary and -Runner mice. Conclusions Treadmill running prevented PSL-induced reductions in GAD65/67 production, and, thus, GABA levels may be retained in interneurons and neuropils in the superficial dorsal horn. Therefore, improvements in impaired GABAergic inhibition may be involved in exercise-induced hypoalgesia. PMID:27030712

    Neuroinflammation plays an important role in the secondary pathophysiological mechanisms of spinal cord injury (SCI) and can exacerbate the primary trauma and thus worsen recovery. Although some aspects of the immune response are beneficial, it is thought that leukocyte recruitment and activation in the acute phase of injury results in the production of cytotoxic substances that are harmful to the nervous tissue. Therefore, suppression of excessive inflammation in the spinal cord could serve as a therapeutic strategy to attenuate tissue damage. The immunosuppressant methylprednisolone has been used in the setting of SCI, but there are complications which have attenuated the initial enthusiasm. Hence, there is interest in other immunomodulatory approaches, such as intravenous Immunoglobulin G (IVIg). Importantly, IVIg is used clinically for the treatment of several auto-immune neuropathies, such as Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy (CIPD) and Kawasaki disease, with a good safety profile. Thus, it is a promising treatment candidate for SCI. Indeed, IVIg has been shown by our team to attenuate the immune response and result in improved neurobehavioral recovery following cervical SCI in rats through a mechanism that involves the attenuation of neutrophil recruitment and reduction in the levels of cytokines and cytotoxic enzymes Nguyen et al. (J Neuroinflammation 9:224, 2012). Here we review published data in the context of relevant mechanisms of action that have been proposed for IVIg in other conditions. We hope that this discussion will trigger future research to provide supporting evidence for the efficiency and detailed mechanisms of action of this promising drug in the treatment of SCI, and to facilitate its clinical translation.

    Intervention to increase exercise in drug dependent patients represents a potentially useful yet unexplored strategy for preventing relapse. However, there are currently no established exercise interventions for use with this population. The purpose of this pilot study was to examine the feasibility of aerobic exercise as an adjunct to substance abuse treatment among drug dependent patients. Participants included 16 (31% female, 38.3 years old) drug dependent patients who participated in a 12-week, moderate-intensity aerobic exercise intervention. Participants attended a mean of 8.6 sessions (out of 12). Participants demonstrated a significant increase in percent days abstinent for both alcohol and drugs at the end of treatment, and those who attended at least 75% of the exercise sessions had significantly better substance use outcomes than those who did not. In addition, participants showed a significant increase in their cardiorespiratory fitness by the end of treatment. While preliminary, this study is one of the first to demonstrate the feasibility of incorporating aerobic exercise during drug abuse treatment. Future randomized control trials are a necessary next step to test the efficacy of a moderate-intensity aerobic exercise intervention as an adjunct to drug abuse treatment in this patient population.

    Purpose: To observe the therapeutic effect of folic acid in combination with adult neural stem cells on spinal cord injury and to investigate the possible mechanism. Methods: A total of 120 Wistar rats were randomly assigned to six groups: normal, model, sham-surgery, folic acid injection, adult neural stem cell transplantation, and combination (folic acid injection + adult neural stem cells transplantation) groups. Morphology of neural stem cells was observed by inverted microscopy. Expression of CD105, CD45, CD44, and CD29 were detected by flow cytometry; expression of neuron-specific enolase and glial fibrillary acidic protein were determined by immunofluorescence. Motor coordination and integration capabilities were assessed using BBB scores; Morphology of spinal cord tissues was observed by hematoxylin-eosin staining and 5-bromodeoxyuridine immunohistochemistry. GDNF, BDNF and NT-3 expression in spinal cord tissues were determined by ELISA; while expression of the apoptosis-related proteins BCL-2, Bax and caspase-3 was detected using western blotting. Results: Flow cytometry showed that the isolated cells were positive for CD44 and CD29 and negative for CD105 and CD45. Combination treatment significantly improved the behavior of model rats with spinal cord injury, attenuated inflammatory reaction of spinal cord tissues, restored injured nerve cells, and increased expression of GDNF, BDNF and NT-3 in spinal cord tissues, up regulated BCL-2 expression, and down regulated Bax and caspase-3 expression. Conclusions: Folic acid in combination with adult neural stem cells significantly improved nerve function and plays a key role in maintaining microenvironment homeostasis in the neurons of rats with spinal cord injury.

  18. Spinal cord stimulation as a treatment for refractory neuropathic pain in tethered cord syndrome: a case report

    PubMed Central

    2010-01-01

    Introduction The spinal cord is a target for many neurosurgical procedures used to treat chronic severe pain. Neuromodulation and neuroablation are surgical techniques based on well-known specific anatomical structures. However, anatomical and electrophysical changes related to the tethered spinal cord make it more difficult to use these procedures. Case presentation We report the case of a 37-year-old Caucasian woman who had several surgical interventions for tethered cord syndrome. These interventions resulted in severe neuropathic pain in her lower back and right leg. This pain was treated by spinal cord stimulation using intra-operative sensory mapping, which allowed the cord's optimal placement in a more caudal position. Conclusion The low-voltage and more caudally placed electrodes are specific features of this treatment of tethered cord syndrome. PMID:20184768

    Phantom limb pain (PLP) is a chronic condition experienced by about 80% of patients who have undergone amputation. In most patients, both the frequency and the intensity of pain attacks diminish with time, but severe pain persists in about 5-10%. Probably, factors in both the peripheral and central nervous system play a role in the occurrence and persistence of pain in the amputated lower limb. The classical treatment of PLP can be divided into pharmacologic, surgical, anesthetic, and psychological modalities. Spinal cord stimulation (SCS) does not represent a new method of treatment for this condition. However, the concomitant treatment of PLP and critical lower limb ischemia by using SCS therapy has not yet been described in the current literature. The aim of the present article is to highlight the possibility of apply SCS for the simultaneous treatment of PLP and critical lower limb ischemia on the contralateral lower limb after failure of medical therapy in a group of 3 patients, obtaining pain relief in both lower limbs, delaying an endovascular or surgical revascularization. After SCS implantation and test stimulation, the pain was reduced by 50% on both the right and the left side in all our patients. The main indications for permanent SCS therapy after 1 week of test stimulation were represented by transcutaneous oxygen (TcPO2) increase >75%, decrease of opioids analgesics use of at least 50% and a pain maintained to within 20-30/100 mm on visual analog scale.

    For patients of type 2 decompression sickness, recompression therapy using U.S. Navy Treatment Table 6 (TT6) and its extensions is the most common means of treatment. However, some cases are resistant to the recompression therapy, and the outcome of TT6 is not always satisfactory. Although a new table, the U.S. Navy Treatment Table 7 (TT7) was described in 1985 in the U.S. Navy Diving Manual, to date few cases who were treated using TT7 have been reported. Here, we report three cases of spinal decompression sickness who received treatment according to TT7. Two were sports scuba divers, and the other a commercial diver. TT7 was applied later than 4 d after onset in all three cases; two patients were remarkably improved during the recompression therapy, while the other improved to a certain extent after additional repetitive TT6. Mild impairment of lung function, probably due to pulmonary oxygen toxicity, was observed on lung function testing in one case. In all cases, after additional TT6 and/or rehabilitation, patients were able to return to active daily living. PMID:10206933

    This work aimed to investigate the therapeutic effect of curcumin on sublesional bone loss induced by spinal cord injury (SCI) in rats. SCI model in this work was generated in rats by surgical transaction of the cord at the T10-12 level. After the surgery, animals were treated with curcumin (110 mg/kg body mass/day, via oral gavages) for 2 weeks. Treatment of SCI rats with curcumin prevented the reduction of bone mass in tibiae and femurs, preserved bone microstructure including trabecular bone volume fraction, trabecular number, and trabecular thickness in proximal tibiae, and preserved mechanical properties of femoral midshaft. Treatment of SCI rats with curcumin increased osteoblast surface and reduced osteoclast surface in proximal tibiae. Treatment of SCI rats with curcumin increased osteocalcin mRNA expression and reduced mRNA levels of tartrate-resistant acid phosphatase and mRNA ratio of receptor activator of NF-κB ligand/osteoprotegerin in distal femurs. Treatment of SCI rats with curcumin reduced serum and femoral levels of thiobarbituric acid reactive substances. Treatment of SCI rats with curcumin had no significant effect on serum 25(OH)D, but enhanced mRNA and protein expression of vitamin D receptor (VDR) in distal femurs. Treatment of SCI rats with curcumin enhanced mRNA levels of Wnt3a, Lrp5, and ctnnb1 and upregulated protein expression of β-catenin in distal femurs. In conclusions, treatment with curcumin abated oxidative stress, activated VDR, and enhanced Wnt/β-catenin pathway, which might explain its beneficial effect against sublesional bone loss following SCI in rats, at least in part.

    Abstract In prior analyses of the effectiveness of methylprednisolone for the treatment of patients with acute traumatic spinal cord injuries (TSCIs), the prognostic importance of patients' neurological levels of injury and their baseline severity of impairment has not been considered. Our objective was to determine whether methylprednisolone improved motor recovery among participants in the Rick Hansen Spinal Cord Injury Registry (RHSCIR). We identified RHSCIR participants who received methylprednisolone according to the Second National Spinal Cord Injury Study (NASCIS-II) protocol and used propensity score matching to account for age, sex, time of neurological exam, varying neurological level of injury, and baseline severity of neurological impairment. We compared changes in total, upper extremity, and lower extremity motor scores using the Wilcoxon signed-rank test and performed sensitivity analyses using negative binomial regression. Forty-six patients received methylprednisolone and 1555 received no steroid treatment. There were no significant differences between matched participants for each of total (13.7 vs. 14.1, respectively; p=0.43), upper extremity (7.3 vs. 6.4; p=0.38), and lower extremity (6.5 vs. 7.7; p=0.40) motor recovery. This result was confirmed using a multivariate model and, as predicted, only cervical (C1–T1) rather than thoracolumbar (T2–L3) injury levels (p<0.01) and reduced baseline injury severity (American Spinal Injury Association [ASIA] Impairment Scale grades; p<0.01) were associated with greater motor score recovery. There was no in-hospital mortality in either group; however, the NASCIS-II methylprednisolone group had a significantly higher rate of total complications (61% vs. 36%; p=0.02) NASCIS-II methylprednisolone did not improve motor score recovery in RHSCIR patients with acute TSCIs in either the cervical or thoracic spine when the influence of anatomical level and severity of injury were included in the analysis.

    The United States is in the midst of a significant public health problem that relates to obesity and inactivity. This epidemic has far-ranging consequences for our workforce and our children and shows no signs of slowing in the near future. Significant research has been performed on the effects of exercise for the reduction of body weight; results of most studies indicate that exercise alone has a small effect on body-weight reduction independent of caloric restriction. However, when combined with dietary restriction, exercise has a synergistic effect and enhances weight loss beyond the effect of diet alone. In addition, exercise has been shown to have significant beneficial effects on cardiovascular and metabolic risk factors independent of actual weight loss, and losing just a small amount of weight can have a significant beneficial effect on these parameters. Genetic factors related to obesity have been found to be positively modified when persons incorporate physical activity into their lifestyle. Sitting time appears to be an independent risk factor for the development of metabolic risk factors; persons who spend more time sitting and watching television have worse metabolic profiles, even if they achieve the recommended amount of physical activity per week, than do those who move about throughout the day. Exercise also is essential for the prevention of weight gain over a life span, although the amount required to prevent weight gain may be closer to twice the amount of exercise recommended by the current Physical Activity Guidelines for Americans (www.health.gov/paguidelines). In many ways, the physiatrist is the most well prepared of all the specialists to address the complex, multidimensional problems of obesity and inactivity. PMID:23174547

    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

    2016-07-01

    There is growing evidence to support the safety and efficacy of exercise in patients with adult and juvenile idiopathic inflammatory myopathies. Five randomized controlled trials including adult patients with polymyositis and dermatomyositis (DM) and additional open studies have demonstrated reduced impairment and activity limitation as well as improved quality of life. In addition, recent studies have shown reduced disease activity assessed by consensus disease activity measures and reduced expression of genes regulating inflammation and fibrosis. Furthermore, exercise could improve muscle aerobic capacity as shown by increased mitochondrial enzyme activity. These data suggest that intensive aerobic exercise and resistance training could reduce disease activity and inflammation and improve muscle metabolism. Encouraging results have been reported from available open studies including patients with inclusion body myositis (IBM) and juvenile DM, indicating reduced impairment, activity limitation and improved quality of life also in these patients. Larger studies are needed to increase understanding of the effects of exercise in patients with active, recent-onset polymyositis and DM as well as in patients with IBM and juvenile DM.

    The effects of exercise on depression have been a source of contentious debate. Meta-analyses have demonstrated a range of effect sizes. Both inclusion criteria and heterogeneity may influence the effect sizes reported. The extent and influence of publication bias is also unknown. Randomized controlled trials (RCTs) were identified from a recent Cochrane review and searches of major electronic databases from 01/2013 to 08/2015. We included RCTs of exercise interventions in people with depression (including those with a diagnosis of major depressive disorder (MDD) or ratings on depressive symptoms), comparing exercise versus control conditions. A random effects meta-analysis calculating the standardized mean difference (SMD, 95% confidence interval; CI), meta-regressions, trim and fill and fail-safe n analyses were conducted. Twenty-five RCTs were included comparing exercise versus control comparison groups, including 9 examining participants with MDD. Overall, exercise had a large and significant effect on depression (SMD adjusted for publication bias = 1.11 (95% CI 0.79-1.43)) with a fail-safe number of 1057. Most adjusted analyses suggested publication bias led to an underestimated SMD. Larger effects were found for interventions in MDD, utilising aerobic exercise, at moderate and vigorous intensities, in a supervised and unsupervised format. In MDD, larger effects were found for moderate intensity, aerobic exercise, and interventions supervised by exercise professionals. Exercise has a large and significant antidepressant effect in people with depression (including MDD). Previous meta-analyses may have underestimated the benefits of exercise due to publication bias. Our data strongly support the claim that exercise is an evidence-based treatment for depression. PMID:26978184

  10. Neuropathic Pain Post Spinal Cord Injury Part 1: Systematic Review of Physical and Behavioral Treatment

    PubMed Central

    2013-01-01

    Background: Neuropathic pain has various physiologic and psychosocial aspects. Hence, there is a growing use of adjunct nonpharmacological therapy with traditional pharmacotherapy to reduce neuropathic pain post spinal cord injury (SCI). Objective: The purpose of this study was to conduct a systematic review of published research on nonpharmacological treatment of neuropathic pain after SCI. Methods: MEDLINE, CINAHL, EMBASE, and PsycINFO databases were searched for articles addressing nonpharmacological treatment of pain post SCI. Articles were restricted to the English language. Article selection was conducted by 2 independent reviewers with the following inclusion criteria: the subjects participated in a treatment or intervention for neuropathic pain; at least 50% of the subjects had an SCI; at least 3 subjects had an SCI; and a definable intervention was being studied. Data extracted included study design, study type, subject demographics, inclusion and exclusion criteria, sample size, outcome measures, and study results. Randomized controlled trials (RCTs) were assessed for quality using the Physiotherapy Evidence Database (PEDro) assessment scale. Levels of evidence were assigned to each intervention using a modified Sackett scale. Results: The 16 articles selected for this review fell into 1 of 2 categories of nonpharmacological management of pain after SCI: physical and behavioral treatments. The pooled sample size of all studies included 433 participants. Of the 16 studies included, 7 were level 1, 3 were level 2, and 6 were level 4 studies. Conclusions: Physical interventions demonstrated the strongest evidence based on quality of studies and numbers of RCTs in the nonpharmacological treatment of post-SCI pain. Of these interventions, transcranial electrical stimulation had the strongest evidence of reducing pain. Despite a growing body of literature, there is still a significant lack of research on the use of nonpharmacological therapies for SCI pain

    Radiotherapy has been the primary therapy for managing metastatic spinal disease; however, surgery that decompresses the spinal cord circumferentially, followed by reconstruction and immediate stabilization, has also proven effective. We provide a quantitative comparison between the “new” surgery and radiotherapy, based on articles that report on ambulatory status before and after treatment, age, sex, primary neoplasm pathology, and spinal disease distribution. Ambulation was categorized as “success” or “rescue” (proportion of patients ambulatory after treatment and proportion regaining ambulatory function, respectively). Secondary outcomes were also analyzed. We calculated cumulative success and rescue rates for our ambulatory measurements and quantified heterogeneity using a mixed-effects model. We investigated the source of the heterogeneity in both a univariate and multivariate manner with a meta-regression model. Our analysis included data from 24 surgical articles (999 patients) and 4 radiation articles (543 patients), mostly uncontrolled cohort studies (Class III). Surgical patients were 1.3 times more likely to be ambulatory after treatment and twice as likely to regain ambulatory function. Overall ambulatory success rates for surgery and radiation were 85% and 64%, respectively. Primary pathology was the principal factor determining survival. We present the first known formal meta-analysis using data from nonrandomized clinical studies. Although we attempted to control for imbalances between the surgical and radiation groups, significant heterogeneity undoubtedly still exists. Nonetheless, we believe the differences in the outcomes indicate a true difference resulting from treatment. We conclude that surgery should usually be the primary treatment with radiation given as adjuvant therapy. Neurologic status, overall health, extent of disease (spinal and extraspinal), and primary pathology all impact proper treatment selection. PMID:15701283

    Pyogenic vertebral osteomyelitis (PVO) is still a rare pathology. However, its incidence is on the rise. This is due to an increasing population with predisposing factors. Also, the availability of more effective diagnostic tools has brought it increasingly to the surgeon's attention. In this study the patients were treated in the Neurosurgery Division of the Department of Neurological Sciences and Psychiatry of the Sapienza University of Rome, between 2001 and 2009. They had thoracolumbar pyogenic spondylitis. This study was undertaken in order to identify the correct diagnostic and therapeutic treatment needed in such cases. From the cases studied here, it is evident that spinal infections can be extremely insidious and that diagnosis tends to be reached late. Surgery, along with the antibiotic treatment, allows for eradication of the causes of the pathology by the reclamation of the affected region. Surgery is also fundamental in helping to recover vital functions and in restoring as much as possible the correct curvature of the rachises. The use of an anterolateral approach is dictated by the necessity of obtaining 360° stability as well as by the need to clear away extensive infections, which are not always reachable using a posterior approach.

    Vertebral metastases are a common manifestation of many cancers, potentially leading to vertebral collapse and neurological complications. Conventional treatment often involves percutaneous vertebroplasty/kyphoplasty followed by external beam radiation therapy. As a more convenient alternative, we have introduced radioactive bone cement, i.e. bone cement incorporating a radionuclide. In this study, we used a previously developed Monte Carlo radiation transport modeling method to evaluate dose distributions from phosphorus-32 radioactive cement in simulated clinical scenarios. Isodose curves were generally concentric about the surface of bone cement injected into cadaveric vertebrae, indicating that dose distributions are relatively predictable, thus facilitating treatment planning (cement formulation and dosimetry method are patent pending). Model results indicated that a therapeutic dose could be delivered to tumor/bone within ∼4 mm of the cement surface while maintaining a safe dose to radiosensitive tissue beyond this distance. This therapeutic range should be sufficient to treat target volumes within the vertebral body when tumor ablation or other techniques are used to create a cavity into which the radioactive cement can be injected. With further development, treating spinal metastases with radioactive bone cement may become a clinically useful and convenient alternative to the conventional two-step approach of percutaneous strength restoration followed by radiotherapy.

    Purpose. The purpose of this study was to evaluate the effectiveness of a new pedicle screw-based posterior dynamic stabilization device PDS Percudyn System Trade-Mark-Sign Anchor and Stabilizer (Interventional Spine Inc., Irvine, CA) as alternative minimally invasive treatment for patients with lumbar spine stenosis. Methods. Twenty-four consecutive patients (8 women, 16 men; mean age 61.8 yr) with lumbar spinal stenosis underwent implantation of the minimally invasive pedicle screw-based device for posterior dynamic stabilization. Inclusion criteria were lumbar stenosis without signs of instability, resistant to conservative treatment, and eligible to traditional surgical posterior decompression. Results. Twenty patients (83 %) progressively improved during the 1-year follow-up. Four (17 %) patients did not show any improvement and opted for surgical posterior decompression. For both responder and nonresponder patients, no device-related complications were reported. Conclusions. Minimally invasive PDS Percudyn System Trade-Mark-Sign has effectively improved the clinical setting of 83 % of highly selected patients treated, delaying the need for traditional surgical therapy.

    Spinal cord ischemia (SCI) is one of the most devastating complications undergoing surgical or endovascular repair of the thoracic aorta. The incidence of SCI after thoracic aorta open repair varies from 2% to 21%, depending on the extent of the descending thoracic aorta replacement compared with as high as 12% of cases after endovascular aortic repair. Endoluminal repair allows the avoidance of aortic cross clamping and its sequelae; however, the intercostal arteries covered by the stent graft cannot be reimplanted. Perioperative risk factors contributing to SCI have been reported to include length of aortic coverage, prior abdominal aortic aneurysm (AAA) repair, hypotension, and left subclavian artery coverage. Although the putative mechanism of loss of lumbar collateral perfusion in those who had prior aortic repairs appears reasonable, occurrence of SCI in this subset of patients has not been consistent. Spinal cord perfusion is dependent on the net pressure of the mean arterial pressure minus the mean intrathecal pressure. Systemic pressure can be maximized by volume resuscitation and vasopressors. Intrathecal spinal pressure can be minimized by drainage of the spinal cord, although this is not without its potential risks. More recently, there have been attempts at attenuating the cellular damage caused by SCI, either with systemic or intrathecal administration of pharmacologic agents, which attempt to mitigate the inflammatory response of cellular reperfusion. This is a review of the risk factors for SCI during TEVAR in patients with previous or concomitant treatment for aortic aneurysm. PMID:20354486

    The authors report the case of a 12-year-old boy with spinal cord arteriovenous malformation (AVM) and an associated anterior spinal artery (ASA) aneurysm treated with selective coil placement in the context of subarachnoid hemorrhage (SAH). The patient presented with headache. Head computed tomography scanning revealed no abnormal findings. The cerebrospinal fluid was sampled and analyzed and a diagnosis of SAH was established. Investigation, including magnetic resonance imaging of the cord as well as cerebral and spinal angiography, revealed a conus medullaris AVM and a saccular aneurysm located on the ASA at the T-11 level. The aneurysm was thought to be responsible for the bleeding. Superselective ASA angiography showed that the aneurysm was at the bifurcation between a large coronal artery supplying the AVM and the ASA. The relation of the aneurysm's neck to the main spinal axis and the aneurysm's morphological features indicated that the lesion was suited for endosaccular coil therapy. The aneurysm was selectively occluded, using electrodetachable bare platinum coils. Follow-up angiography immediately after surgery and at 6 months thereafter demonstrated complete occlusion of the aneurysm and a perfectly patent anterior spinal axis. On clinical follow-up examination, the patient remained neurologically intact. When the morphological features of a spinal aneurysm and its relation with the anterior spinal axis are favorable, selective endosaccular coil placement can successfully be achieved. PMID:17542515

    After spinal cord injury (SCI), poor regeneration of damaged axons of the central nervous system (CNS) causes limited functional recovery. This limited spontaneous functional recovery has been attributed, to a large extent, to the plasticity of propriospinal neurons, especially the descending propriospinal neurons (dPSNs). Compared with the supraspinal counterparts, dPSNs have displayed significantly greater regenerative capacity, which can be further enhanced by glial cell line-derived neurotrophic factor (GDNF). In the present study, we applied a G-mutated rabies virus (G-Rabies) co-expressing green fluorescence protein (GFP) to reveal Golgi-like dendritic morphology of dPSNs. We also investigated the neurotransmitters expressed by dPSNs after labeling with a retrograde tracer Fluoro-Gold (FG). dPSNs were examined in animals with sham injuries or complete spinal transections with or without GDNF treatment. Bilateral injections of G-Rabies and FG were made into the 2nd lumbar (L2) spinal cord at 3 days prior to a spinal cord transection performed at the 11th thoracic level (T11). The lesion gap was filled with Gelfoam containing either saline or GDNF in the injury groups. Four days post-injury, the rats were sacrificed for analysis. For those animals receiving G-rabies injection, the GFP signal in the T7-9 spinal cord was visualized via 2-photon microscopy. Dendritic morphology from stack images was traced and analyzed using a Neurolucida software. We found that dPSNs in sham injured animals had a predominantly dorsal-ventral distribution of dendrites. Transection injury resulted in alterations in the dendritic distribution with dorsal-ventral retraction and lateral-medial extension. Treatment with GDNF significantly increased the terminal dendritic length of dPSNs. The density of spine-like structures was increased after injury, and treatment with GDNF enhanced this effect. For the group receiving FG injections, immunohistochemistry for glutamate, choline

    Narrowing of the spinal canal or foramina is a common finding in spine imaging of the elderly. Only when symptoms of neurogenic claudication and/or cervical myelopathy are present is a spinal stenosis diagnosis made, either of the lumbar spine, cervical spine or both (only very rarely is the thoracic spine involved). Epidemiological data suggest an incidence of 1 case per 100 000 for cervical spine stenosis and 5 cases per 100 000 for lumbar spine stenosis. Cervical myelopathy in patients over 50 years of age is most commonly due to cervical spine stenosis. Symptomatic spinal narrowing can be congenital, or, more frequently, acquired. The latter may be the result of systemic illneses, namely endocrinopathies (such as Cushing disease or acromegaly), calcium metabolism disorders (including hyporarthyroidism and Paget disease), inflammatory diseases (such as rheumathoid arthritis) and infectious diseases. Physical examination is more often abnormal in cervical spondylotic myeloptahy whereas in lumbar spinal stenosis it is typically normal. Therefore spinal stenosis diagnosis relies on the clinical picture corresponding to conspicuous causative changes identified by imaging techniques, most importantly CT and MRI. Other ancillary diagnostic tests are more likely to be yielding for establishing a differential diagnosis, namely vascular claudication. Most patients have a progressive presentation and are offered non operative management as first treatment strategy. Surgery is indicated for progressive intolerable symptoms or, more rarely, for the neurologically catastrophic initial presentations. Surgical strategy consists mainly of decompression (depending on the anatomical level and type of narrowing: laminectomy, foraminotomy, discectomy, corporectomy) with additional instrumentation should spinal stability and sagittal balance be at risk. For cervical spine stenosis the main objective of surgery is to halt disease progression. There is class 1b evidence that surgery

    Spinal cord injury (SCI) often represents a condition of permanent neurologic deficit. It has been possible to understand and delineate the mechanisms contributing to loss of function following primary injury. The clinicians might hope to improve the outcome in SCI injury by designing treatment strategies that could target these secondary mechanisms of response to injury. However, the approaches like molecular targeting of the neurons or surgical interventions have yielded very limited success till date. In recent times, a great thrust is put on to the cellular transplantation mode of treatment strategies to combat SCI problems so as to gain maximum functional recovery. In this review, we discuss about the various cellular transplantation strategies that could be employed in the treatment of SCI. The success of such cellular approaches involving Schwann cells, olfactory ensheathing cells, peripheral nerve, embryonic CNS tissue and activated macrophage has been supported by a number of reports and has been detailed here. Many of these cell transplantation strategies have reached the clinical trial stages. Also, the evolving field of stem cell therapy has made it possible to contemplate the role of both embryonic stem cells and induced pluripotent stem cells to stimulate the differentiation of neurons when transplanted in SCI models. Moreover, the roles of tissue engineering techniques and synthetic biomaterials have also been explained with their beneficial and deleterious effects. Many of these cell-based therapeutic approaches have been able to cause only a little change in recovery and a combinatorial approach involving more than one strategy are now being tried out to successfully treat SCI and improve functional recovery.

    Context Pressure ulcers are especially difficult to treat in patients with spinal cord injury (SCI) and recurrence rates are high. Prompted by encouraging results obtained using bone marrow stem cells to treat several diseases including chronic wounds, this study examines the use of autologous stem cells from bone marrow to promote the healing of pressure ulcers in patients with SCI. Objective To obtain preliminary data on the use of bone marrow mononuclear cells (BM-MNCs) to treat pressure ulcers in terms of clinical outcome, procedure safety, and treatment time. Participants Twenty-two patients with SCI (19 men, 3 women; mean age 56.41 years) with single type IV pressure ulcers of more than 4 months duration. Interventions By minimally invasive surgery, the ulcers were debrided and treated with BM-MNCs obtained by Ficoll density gradient separation of autologous bone marrow aspirates drawn from the iliac crest. Results In 19 patients (86.36%), the pressure ulcers treated with BM-MNCs had fully healed after a mean time of 21 days. The number of MNCs isolated was patient dependent, although similar clinical outcomes were observed in each case. Compared to conventional surgical treatment, mean intra-hospital stay was reduced from 85.16 to 43.06 days. Following treatment, 5 minutes of daily wound care was required per patient compared to 20 minutes for conventional surgery. During a mean follow-up of 19 months, none of the resolved ulcers recurred. Conclusions Our data indicate that cell therapy using autologous BM-MNCs could be an option to treat type IV pressure ulcers in patients with SCI, avoiding major surgical intervention. PMID:21756569

Methods On separate days, nine individuals with a motor complete paraplegia or tetraplegia (eight men, age 40 ± 13 years, time since injury 12 ± 10 years) performed 5-minute bouts of hybrid cycling (day 1) and handcycling (day 2) at moderate (level 3 on a 10-point rating of perceived exertion (RPE) scale) and vigorous (RPE level 6) subjective exercise intensity, while respiratory gas exchange was measured by open-circuit spirometry and heart rate was monitored using radiotelemetry. Outcome measures Metabolic rate (calculated with the Weir equation) and cardiorespiratory response (heart rate, oxygen pulse, and ventilation). Results Overall, the metabolic rate during hybrid cycling was 3.4 kJ (16%) higher (P = 0.006) than during handcycling. Furthermore, compared with handcycling, the overall heart rate and ventilation during hybrid cycling was 11 bpm (11%) and 5.3 l/minute (18%) higher (P = 0.004 and 0.024), respectively, while the oxygen pulse was the same (P = 0.26). Conclusion Hybrid cycling induces a higher metabolic rate and cardiorespiratory response at equal RPE levels than handcycling, suggesting that hybrid cycling is more suitable for fighting obesity and increasing cardiorespiratory fitness in individuals with SCI.

    Interest in Central Nervous System (CNS) inflammation has rapidly grown over the past decade driven by the increasing evidence indicating that chronic inflammation and neuroinflammation in the brain may play an important role in the progressive neuronal cell death in many chronic CNS diseases, such as Alzheimer and Parkinson's diseases, traumatic brain injury, spinal cord injury (SCI), as well as pathologies associated with CNS infections. In peripheral tissues, generally inflammation has a protective role limiting the survival and proliferation of invading pathogens, promoting tissue repair and recovery. This innate response normally resolves over a few weeks, accompanyied by tissue repair aided by macrophages recruited to the site. However, when the inflammatory response does not undergo resolution, it might turn into chronic inflammation. Any chronic inflammatory process can damage healthy tissue and the brain may be particularly vulnerable, since destroyed neurons can not be replaced. Recently, several reports have suggested that phosphodiesterases (PDEs) are new targets for central nervous system (CNS) diseases. All the PDEs are expressed in the CNS, making this gene family a particularly attractive source of new targets for the treatment of psychiatric and neurodegenerative disorders. Significantly, all neurons express multiple PDEs, which differ in cyclic nucleotide specificity, affinity, regulatory control and subcellular compartmentalization. Therefore, PDEs inhibition represents a mechanism through which it could be possible to precisely modulate neuronal activity. In this article, we review the current state of art of PDEs in the CNS diseases associated with neuroinflammation. PMID:24533816

    Electrical stimulation for bladder control is an alternative to traditional methods of treating neurogenic lower urinary tract dysfunction (NLUTD) resulting from spinal cord injury (SCI). In this review, we systematically discuss the neurophysiology of bladder dysfunction following SCI and the applications of electrical stimulation for bladder control following SCI, spanning from historic clinical approaches to recent pre-clinical studies that offer promising new strategies that may improve the feasibility and success of electrical stimulation therapy in patients with SCI. Electrical stimulation provides a unique opportunity to control bladder function by exploiting neural control mechanisms. Our understanding of the applications and limitations of electrical stimulation for bladder control has improved due to many pre-clinical studies performed in animals and translational clinical studies. Techniques that have emerged as possible opportunities to control bladder function include pudendal nerve stimulation and novel methods of stimulation, such as high frequency nerve block. Further development of novel applications of electrical stimulation will drive progress towards effective therapy for SCI. The optimal solution for restoration of bladder control may encompass a combination of efficient, targeted electrical stimulation, possibly at multiple locations, and pharmacological treatment to enhance symptom control.

    Summary: Spinal cord injury (SCI) often leads to an impairment of the respiratory system. The more rostral the level of injury, the more likely the injury will affect ventilation. In fact, respiratory insufficiency is the number one cause of mortality and morbidity after SCI. This review highlights the progress that has been made in basic and clinical research, while noting the gaps in our knowledge. Basic research has focused on a hemisection injury model to examine methods aimed at improving respiratory function after SCI, but contusion injury models have also been used. Increasing synaptic plasticity, strengthening spared axonal pathways, and the disinhibition of phrenic motor neurons all result in the activation of a latent respiratory motor pathway that restores function to a previously paralyzed hemidiaphragm in animal models. Human clinical studies have revealed that respiratory function is negatively impacted by SCI. Respiratory muscle training regimens may improve inspiratory function after SCI, but more thorough and carefully designed studies are needed to adequately address this issue. Phrenic nerve and diaphragm pacing are options available to wean patients from standard mechanical ventilation. The techniques aimed at improving respiratory function in humans with SCI have both pros and cons, but having more options available to the clinician allows for more individualized treatment, resulting in better patient care. Despite significant progress in both basic and clinical research, there is still a significant gap in our understanding of the effect of SCI on the respiratory system. PMID:17853653

    Spontaneous spinal subdural haematoma (SSDH) with no underlying pathology is a very rare condition. Only 20 cases have been previously reported. It can be caused by abnormalities of coagulation, blood dyscrasia, or trauma, underlying neoplasm, and arteriovenous malformation. It occurs most commonly in the thoracic spine and presents with sudden back pain radiating to the arms, legs or trunk, and varying degrees of motor, sensory, and autonomic disturbances. Although the main approach to management is surgical decompression, conservative management is used as well. We report the case of a 57-year-old man who presented with sudden severe low back pain followed by rapid onset of complete paraplegia. Magnetic resonance imaging (MRI) revealed an anterior subdural haematoma from T9 to L1 with cord compression. Corticosteroid treatment was administered. The patient showed substantial clinical improvement after 7 days of bed rest and an intense rehabilitation programme. An MRI scan and a computed tomography angiogram did not reveal any underlying pathology to account for the subdural haematoma. PMID:22065983

    Research in spine surgery has proposed new soft and less invasive techniques. These are the results of our experience with oxygen-ozone therapy, which we could experiment within the Italian National Health System over 3 years. A total of 1,920 patients were admitted on the basis of unselected enrolment because of lumbosciatic pain. Patients were divided into three groups: (A) Patients with degenerative disc disease and arthropathy: 509 (26.5%), (B) Patients with failed back surgery syndrome (FBSS): 1,027 (53.489%), and (C) Patients with pure herniated lumbar disc: 384 (20%). The rationale of the treatment for all these different pathologies we have taken into consideration is the biochemical mechanism by which they can engender pain and dysfunction. Treatment for group A: paravertebral injection and phleboclysis (two cycles of 6 sessions, one each 3 days) +endoscopic neurolysis. Treatment for group B: paravertebral injection and phleboclysis (two cycles of 6 sessions, one each 3 days) + endoscopic neurolysis with intradiscal procedure (named percutaneous peridurodiscolysis). Treatment for group C: paravertebral injection (two cycles of 6 sessions, one each 3 days) + percutaneous discolysis.The perceived quality of result for this minimally invasive procedure makes oxygen-ozone therapy an interesting weapon in the hands of doctors. Furthermore, if the technique loses its clinical effectiveness, it can be repeated without harm for the patient, and costs for the health organization are notably very low, above all if compared to surgical procedures.We underline the need that this treatment should be performed in protected structures, in operative rooms, under anesthesiologic control, and in the hands of specialists.

    Cervical somatosensory evoked potentials, brainstem evoked potentials, visual evoked potentials, and the cerebral contingent negative variation were recorded in patients with definite multiple sclerosis before, during, and after spinal cord stimulation. Improvements were seen in the cervical somatosensory and brainstem evoked potentials but neither the visual evoked potential nor the contingent negative variation changed in association with spinal cord stimulation. The results indicate that spinal cord stimulation acts at spinal and brainstem levels and that the clinical improvements seen in patients are caused by an action at these levels rather than by any cerebral arousal or motivational effect. The evoked potentials were not useful in predicting which patients were likely to respond to stimulation. PMID:7354352

    Intramedullary spinal cord metastasis of non-small cell lung cancer is rare, and it has a short prognosis. We report a 53-year-old man diagnosed with cT4N0M0, stage IIIA squamous cell lung cancer. Ten months after left pneumonectomy (pT4N0M0), an intramedullary spinal cord tumor developed at the axis level. The intramedullary spinal cord tumor was resected, and he was diagnosed with metastatic squamous cell lung cancer. Radiotherapies and another tumor resection were conducted, as he had a good performance status and the discrete lesion was associated with the risk of brain stem compression. Multimodal local treatments for intramedullary spinal cord metastasis caused the tumor to shrink, and he lived for 25 months after the spinal metastasis occurred. PMID:27621899

    [Purpose] The aim of this study was to analyze the effectiveness of conservative treatment of patellofemoral pain syndrome with physical exercise. [Subjects and Methods] A computer-based review conducted of four databases (PubMed, the Cochrane Library, PEDro, and the University Library) was completed based on the inclusion criteria of patellofemoral pain syndrome patients treated with physical exercise methods and examination with self-reported pain and/or functional questionnaires. [Results] The findings of ten clinical trials of moderate to high quality were evaluated to determine the effectiveness of physical exercise as conservative management for patellofemoral pain syndrome. [Conclusion] The intervention programs that were most effective in relieving pain and improving function in patellofemoral pain syndrome included proprioceptive neuromuscular facilitation stretching and strengthening exercises for the hip external rotator and abductor muscles and knee extensor muscles.
