RESUMO
OBJECTIVE: To identify the optimal dose and modality of exercise for treating major depressive disorder, compared with psychotherapy, antidepressants, and control conditions. DESIGN: Systematic review and network meta-analysis. METHODS: Screening, data extraction, coding, and risk of bias assessment were performed independently and in duplicate. Bayesian arm based, multilevel network meta-analyses were performed for the primary analyses. Quality of the evidence for each arm was graded using the confidence in network meta-analysis (CINeMA) online tool. DATA SOURCES: Cochrane Library, Medline, Embase, SPORTDiscus, and PsycINFO databases. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Any randomised trial with exercise arms for participants meeting clinical cut-offs for major depression. RESULTS: 218 unique studies with a total of 495 arms and 14 170 participants were included. Compared with active controls (eg, usual care, placebo tablet), moderate reductions in depression were found for walking or jogging (n=1210, κ=51, Hedges' g -0.62, 95% credible interval -0.80 to -0.45), yoga (n=1047, κ=33, g -0.55, -0.73 to -0.36), strength training (n=643, κ=22, g -0.49, -0.69 to -0.29), mixed aerobic exercises (n=1286, κ=51, g -0.43, -0.61 to -0.24), and tai chi or qigong (n=343, κ=12, g -0.42, -0.65 to -0.21). The effects of exercise were proportional to the intensity prescribed. Strength training and yoga appeared to be the most acceptable modalities. Results appeared robust to publication bias, but only one study met the Cochrane criteria for low risk of bias. As a result, confidence in accordance with CINeMA was low for walking or jogging and very low for other treatments. CONCLUSIONS: Exercise is an effective treatment for depression, with walking or jogging, yoga, and strength training more effective than other exercises, particularly when intense. Yoga and strength training were well tolerated compared with other treatments. Exercise appeared equally effective for people with and without comorbidities and with different baseline levels of depression. To mitigate expectancy effects, future studies could aim to blind participants and staff. These forms of exercise could be considered alongside psychotherapy and antidepressants as core treatments for depression. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42018118040.

BACKGROUND: Persistent pain is a highly prevalent, global cause of disability. Research suggests that many healthcare professionals are not well equipped to manage pain, and this may be attributable at least in part to undergraduate education. The primary aim of this study was to quantify and compare first and final year nursing, midwifery and allied health professional (NMAHP) students' pain related knowledge and attitudes. The secondary aim was to explore what factors influence students' pain related knowledge and attitudes. METHODS: In this cross-sectional study, 1154 first and final year healthcare students, from 12 universities in five different countries completed the Revised Neurophysiology of Pain Quiz (RNPQ) [knowledge] and the Health Care Providers Pain and Impairment Relationship Scale (HC-PAIRS) [attitudes]. RESULTS: Physiotherapy was the only student group with statistically and clinically improved pain related knowledge [mean difference, 95% CI] (3.4, 3.0 to 3.9, p = 0.01) and attitudes (-17.2, -19.2 to 15.2, p = 0.01) between first and final year. Pain education teaching varied considerably from course to course (0 to 40 h), with greater levels of pain related knowledge and attitudes associated with higher volumes of pain specific teaching. CONCLUSIONS: There was little difference in pain knowledge and attitudes between all first and final year NMAHP students other than physiotherapy. This suggests that for most NMAHP disciplines, undergraduate teaching has little or no impact on students' understanding of pain. There is an urgent need to enhance pain education provision at the undergraduate level in NMAHPs. TRIAL REGISTRATION: The study protocol was prospectively registered at ClinicalTrials.Gov NCT03522857 .

Maternal obesity (MO) leads to offspring metabolic problems. The mechanisms involved are multifactorial. The small intestine plays an important role in the absorption of nutrients and is modified as we age. Few studies have explored MO programming effects on offspring (F1) small intestine morphology. The aim of this study was to investigate MO effects on old adult F1 intestinal morphology, and whether any F1 intestinal changes due to MO were modified by maternal resveratrol supplementation. From weaning throughout pregnancy and lactation, female Wistar rats (F0) ate standard chow (controls, C: 5%-fat) or high-fat diet (MO: 25%-fat). One month before mating at postnatal day (PND) 120 through lactation half of each group received 20 mg/kg/day of resveratrol orally (Cres or MOres). After weaning F1 were fed with chow diet until the end of the study at PND 650. Body weight, percent of fat, glucose, cholesterol and triglyceride serum concentrations were determined. F1 small intestinal samples were collected for histological analysis. Male F1 body weight was higher in MO and MOres compared with C and Cres. Female F1 body weight and percent of fat was higher in MO than C and MOres. Triglyceride concentrations were higher in MO and MOres male F1 compared with C and Cres. There were no differences among groups in female triglyceride concentrations. Male F1 duodenal villus height was smaller in MO compared with MOres. Female F1 duodenal and jejunal crypt depth was smaller in MO compared with C and was greater compared with MOres. Female F1 villus height in jejunum was greater in MO compared with MOres. In conclusion, exposure to the developmental challenge of MO changed the aged F1 intestinal morphological and metabolic profiles. Maternal resveratrol supplementation ameliorated these effects in an F1 sex dependent manner.

OBJECTIVES: To assess the feasibility of a multi-site randomised controlled trial to evaluate the effect of functional electrical stimulation on bradykinesia in people with Parkinson's disease. DESIGN: A two-arm assessor blinded randomised controlled trial with an 18 weeks intervention period and 4 weeks post-intervention follow-up. SETTING: Two UK hospitals; a therapy outpatient department in a district general hospital and a specialist neuroscience centre. PARTICIPANTS: A total of 64 participants with idiopathic Parkinson's disease and slow gait <1.25 ms-1. INTERVENTIONS: Functional electrical stimulation delivered to the common peroneal nerve while walking in addition to standard care compared with standard care alone. MAIN MEASURES: Feasibility aims included the determination of sample size, recruitment and retention rates, acceptability of the protocol and confirmation of the primary outcome measure. The outcome measures were 10 m walking speed, Unified Parkinson's Disease Rating Scale (UPDRS), Mini Balance Evaluation Systems Test, Parkinson's Disease Questionnaire-39, EuroQol 5-dimension 5-level, New Freezing of Gait questionnaire, Falls Efficacy Score International and falls diary. Participants opinion on the study design and relevance of outcome measures were evaluated using an embedded qualitative study. RESULTS: There was a mean difference between groups of 0.14 ms-1 (CI 0.03, 0.26) at week 18 in favour of the treatment group, which was maintained at week 22, 0.10 ms-1 (CI -0.05, 0.25). There was a mean difference in UPDRS motor examination score of -3.65 (CI -4.35, 0.54) at week 18 which was lost at week 22 -0.91 (CI -2.19, 2.26). CONCLUSION: The study design and intervention were feasible and supportive for a definitive trial. While both the study protocol and intervention were acceptable, recommendations for modifications are made.

The rehabilitation of patients with COVID-19 after prolonged treatment in the intensive care unit is often complex and challenging. Patients may develop a myriad of long-term multiorgan impairments, affecting the respiratory, cardiac, neurological, digestive and musculoskeletal systems. Skeletal muscle dysfunction of respiratory and limb muscles, commonly referred to as intensive care unit acquired weakness, occurs in approximately 40% of all patients admitted to intensive care. The impact on mobility and return to activities of daily living is severe. Furthermore, many patients experience ongoing symptoms of fatigue, weakness and shortness of breath, in what is being described as "long COVID". Neuromuscular electrical stimulation is a technique in which small electrical impulses are applied to skeletal muscle to cause contractions when voluntary muscle contraction is difficult or impossible. Neuromuscular electrical stimulation can prevent muscle atrophy, improve muscle strength and function, maintain blood flow and reduce oedema. This review examines the evidence, current guidelines, and proposed benefits of using neuromuscular electrical stimulation with patients admitted to the intensive care unit. Practical recommendations for using electrical muscle stimulation in patients with COVID-19 are provided, and suggestions for further research are proposed. Evidence suggests NMES may play a role in the weaning of patients from ventilators and can be continued in the post-acute and longer-term phases of recovery. As such, NMES may be a suitable treatment modality to implement within rehabilitation pathways for COVID-19, with consideration of the practical and safety issues highlighted within this review.

Meta-analysis of neuroimaging results has proven to be a popular and valuable method to study human brain functions. A number of studies have used meta-analysis to parcellate distinct brain regions. A popular way to perform meta-analysis is typically based on the reported activation coordinates from a number of published papers. However, in addition to the coordinates associated with the different brain regions, the text itself contains considerably amount of additional information. This textual information has been largely ignored in meta-analyses where it may be useful for simultaneously parcellating brain regions and studying their characteristics. By leveraging recent advances in document clustering techniques, we introduce an approach to parcellate the brain into meaningful regions primarily based on the text features present in a document from a large number of studies. This new method is called MAPBOT (Meta-Analytic Parcellation Based On Text). Here, we first describe how the method works and then the application case of understanding the sub-divisions of the thalamus. The thalamus was chosen because of the substantial body of research that has been reported studying this functional and structural structure for both healthy and clinical populations. However, MAPBOT is a general-purpose method that is applicable to parcellating any region(s) of the brain. The present study demonstrates the powerful utility of using text information from neuroimaging studies to parcellate brain regions.

OBJECTIVE: To examine the evidence for a training effect on the lower limb of functional electrical stimulation. DESIGN: Cohort study. PATIENTS: A total of 133 patients >6 months post-stroke. METHODS: Training and orthotic effects were determined from walking speed over 10 m, associated minimal and substantial clinically important differences (i.e. >0.05 and >0.10 m/s), and Functional Ambulation Category (FAC), ranging from household walking to independent walking in the community. RESULTS: An overall significant (p < 0.01) training effect was found that was not a clinically important difference (0.02 m/s); however, "community" FAC (≥ 0.8 m/s) and "most limited community walkers" FAC (0.4-0.58 m/s), but not "household walkers" (< 0.4 m/s), benefitted from a clinically important difference. A highly significant (p< 0.001), substantial clinically important orthotic effect (0.10 m/s) was found. In terms of overall improvement of one or more FACs, 23% achieved this due to a training effect, compared with 43% due to an orthotic effect. CONCLUSION: The findings suggest that functional electrical stimulation provides a training effect in those who are less impaired. Further work, which optimizes the use of the device for restoration of function, rather than as an orthotic device, will provide greater clarity on the effectiveness of functional electrical stimulation for eliciting a training effect.

Various studies have indicated that the thalamus is involved in controlling both cortico-cortical information flow and cortical communication with the rest of the brain. Detailed anatomy and functional connectivity patterns of the thalamocortical system are essential to understanding the cortical organization and pathophysiology of a wide range of thalamus-related neurological and neuropsychiatric diseases. The current study used resting-state fMRI to investigate the topography of the human thalamocortical system from a functional perspective. The thalamus-related cortical networks were identified by performing independent component analysis on voxel-based thalamic functional connectivity maps across a large group of subjects. The resulting functional brain networks were very similar to well-established resting-state network maps. Using these brain network components in a spatial regression model with each thalamic voxel's functional connectivity map, we localized the thalamic subdivisions related to each brain network. For instance, the medial dorsal nucleus was shown to be associated with the default mode, the bilateral executive, the medial visual networks; and the pulvinar nucleus was involved in both the dorsal attention and the visual networks. These results revealed that a single nucleus may have functional connections with multiple cortical regions or even multiple functional networks, and may be potentially related to the function of mediation or modulation of multiple cortical networks. This observed organization of thalamocortical system provided a reference for studying the functions of thalamic sub-regions. The importance of intrinsic connectivity-based mapping of the thalamocortical relationship is discussed, as well as the applicability of the approach for future studies.

OBJECTIVE: The objective of this study was to evaluate possible mechanisms for functional improvement and compare ambulation training with surface peroneal nerve stimulation vs. usual care via quantitative gait analysis. DESIGN: This study is a randomized controlled clinical trial. SETTING: The setting of this study is a teaching hospital of an academic medical center. PARTICIPANTS: One hundred ten chronic stroke survivors (>12 wks poststroke) with unilateral hemiparesis participated in this study. INTERVENTIONS: The subjects were randomized to a surface peroneal nerve stimulation device or usual care intervention. The subjects were treated for 12 wks and followed up for 6-mo posttreatment. MAIN OUTCOME MEASURES: Spatiotemporal, kinematic, and kinetic parameters of gait were the main outcome measures. RESULTS: Cadence (F3,153 = 5.81, P = 0.012), stride length (F3,179 = 20.01, P < 0.001), walking speed (F3,167 = 18.2, P < 0.001), anterior-posterior ground reaction force (F3,164 = 6.61, P = 0.004), peak hip power in preswing (F3,156 = 8.76, P < 0.001), and peak ankle power at push-off (F3,149 = 6.38, P = 0.005) all improved with respect to time. However, peak ankle ankle dorsiflexion in swing (F3,184 = 4.99, P = 0.031) worsened. In general, the greatest change for all parameters occurred during the treatment period. There were no significant treatment group × time interaction effects for any of the spatiotemporal, kinematic, or kinetic parameters. CONCLUSIONS: Gait training with peroneal nerve stimulation and usual care was associated with improvements in peak hip power in preswing and peak ankle power at push-off, which may have resulted in improved cadence, stride length, and walking speed; however, there were no differences between treatment groups. Both treatment groups also experienced a decrease in peak ankle ankle dorsiflexion in swing, although the clinical implications of this finding are unclear.

OBJECTIVE: To determine the effectiveness of functional electrical stimulation (FES) on drop foot in patients with multiple sclerosis (MS), using data from standard clinical practice. DESIGN: Case series with a consecutive sample of FES users collected between 2008 and 2013. SETTING: Specialist FES center at a district general hospital. PARTICIPANTS: Patients with MS who have drop foot (N=187) (117 women, 70 men; mean age, 55y [range, 27-80y]; mean duration since diagnosis, 11.7y [range, 1-56y]). A total of 166 patients were still using FES after 20 weeks, with 153 patients completing the follow-up measures. INTERVENTIONS: FES of the common peroneal nerve (178 unilateral, 9 bilateral FES users). MAIN OUTCOME MEASURES: Clinically meaningful changes (ie, >.05m/s and >0.1m/s) and functional walking category derived from 10-m walking speed. RESULTS: An increase in walking speed was found to be highly significant (P<.001), both initially where a minimum clinically meaningful change was observed (.07m/s) and after 20 weeks with a substantial clinically meaningful change (.11m/s). After 20 weeks, treatment responders displayed a 27% average improvement in their walking speed. No significant training effect was found. Overall functional walking category was maintained or improved in 95% of treatment responders. CONCLUSIONS: FES of the dorsiflexors is a well-accepted intervention that enables clinically meaningful changes in walking speed, leading to a preserved or an increased functional walking category.

OBJECTIVE: To examine the effect of Functional Electrical Stimulation (FES) for dropped foot and hip instability in combination with physiotherapy core stability exercises. METHODS: Twenty-eight people with secondary progressive multiple sclerosis and unilateral dropped foot participated in a randomized crossover trial. Group1 received FES for correction of dropped foot for six weeks with the addition of hip extension for a further six weeks. In weeks 12-18, FES was continued with the addition of eight sessions of core stability physiotherapy with home-based exercise. FES and home-based exercise were continued until weeks 19-24. Group 2 received the same physiotherapy intervention over the first 12 weeks, adding FES in the second 12 weeks. RESULTS: FES improved walking speed and Rivermead Observational Gait Analysis (ROGA) score, whereas physiotherapy did not. Adding gluteal stimulation further improved ROGA score. Both interventions reduced falls, but adding FES to physiotherapy reduced them further. FES had greater impact on Multiple Sclerosis Impact Scale, MSIS-29. CONCLUSION: The intervention was feasible. FES for dropped foot may improve mobility and quality of life and may reduce falls. Adding gluteal stimulation further improved gait quality. Adding physiotherapy may have enhanced the effect of FES, but FES had the dominant effect.

Telehealth can be viewed as an intervention in the established and stable clinician-patient system with outcomes that are not always predictable. The success of a new telehealth service depends far more on changing the clinicians and patient's expectations and patterns of behaviour than on technology. Success in telehealth projects is critically dependent on understanding how the new telehealth offering changes the distinct value proposition for each of the parties - clinicians, patients and administrators. As with any intervention, design is the key to ensuring more predictable outcomes. An approach to the design of telehealth services is described that takes a holistic view of telehealth by acknowledging the multiple and interdependent dimensions of telehealth services (clinical process change, clinical risk and governance, adoption and change management, clinician and patient experience, operational sustainability, support, and least of all, technology). The approach draws on current themes in design including 'design thinking' and service design.

OBJECTIVE: To compare the motor relearning effect of a surface peroneal nerve stimulator (PNS) versus usual care on lower limb motor impairment, activity limitation, and quality of life among chronic stroke survivors. DESIGN: Single-blinded randomized controlled trial. SETTING: Teaching hospital of academic medical center. PARTICIPANTS: Chronic stroke survivors (N=110; >12wk poststroke) with unilateral hemiparesis and dorsiflexion strength of ≤4/5 on the Medical Research Council scale. INTERVENTIONS: Subjects were stratified by motor impairment level and then randomly assigned to ambulation training with either a surface PNS device or usual care (ankle-foot orthosis or no device) intervention. Subjects were treated for 12 weeks and followed up for 6 months posttreatment. MAIN OUTCOME MEASURES: Lower limb portion of the Fugl-Meyer (FM) Assessment (motor impairment), the modified Emory Functional Ambulation Profile (mEFAP) performed without a device (functional ambulation), and the Stroke Specific Quality of Life (SSQOL) scale. RESULTS: There was no significant treatment group main effect or treatment group by time interaction effect on FM, mEFAP, or SSQOL raw scores (P>.05). The time effect was significant for the 3 raw scores (P<.05). However, when comparing average change scores from baseline (t1) to end of treatment (t2, 12wk), and at 12 weeks (t3) and 24 weeks (t4) after end of treatment, significant differences were noted only for the mEFAP and SSQOL scores. The change in the average scores for both mEFAP and SSQOL occurred between t1 and t2, followed by relative stability thereafter. CONCLUSIONS: There was no evidence of a motor relearning effect on lower limb motor impairment in either the PNS or usual-care groups. However, both the PNS and usual-care groups demonstrated significant improvements in functional mobility and quality of life during the treatment period, which were maintained at 6-month follow-up.

OBJECTIVE: Functional Electrical Stimulation (FES) for correction of dropped foot has been shown to increase mobility, reduce the incidence of falls and to improve quality of life. This study aimed to determine how long the intervention is of benefit, and the total cost of its provision. DESIGN: Retrospective review of medical records. PARTICIPANTS: One hundred and twenty-six people with spastic dropped foot (62 stroke, 39 multiple sclerosis, 7 spinal cord injury, 3 cerebral palsy, 15 others) who began treatment in the year 1999. METHOD: All received common peroneal nerve stimulation, producing dorsiflexion and eversion time to the swing phase of gait using a heel switch. Device usage, 10 m walking speed and Functional Walking Category (FWC) were recorded. RESULTS: The median time of FES use was 3.6 years (mean 4.9, standard deviation 4.1, 95% confidence interval 4.2-5.6) with 33 people still using FES after a mean of 11.1 years. People with stroke walked a mean of 45% faster overall, including a 24% training effect with 52% improving their FWC. People with multiple sclerosis did not receive a consistent training effect but walked 29% faster when FES was used with 40% increasing their FWC. The average treatment cost was £3,095 per patient resulting in a mean cost per Quality Adjusted Life Years of £15,406. CONCLUSION: FES is a practical, long-term and cost-effective treatment for correction of dropped foot.

OBJECTIVES: To investigate in people with spastic paraparesis (SP): 1) the factors contributing to foot drop and reduced toe clearance while walking; 2) short-term effects of bilateral functional electrical stimulation (FES) of the common peroneal nerve. MATERIALS AND METHODS: Long term (>0.5 years) users of FES with SP were compared to matched controls (N = 11 per group). Ankle strength and plantarflexor stiffness and walking kinematics were objectively recorded. The effects of FES on: 1) perceived efficacy; 2) muscle torque and ankle motion; 3) clinical outcome measures and walking kinematics were assessed. Results were compared using an analysis of covariance. RESULTS: Ankle weakness and stiffness is higher among people with SP. Higher plantarflexor stiffness is associated with reduced swing phase dorsiflexion; higher toe clearance while walking is associated with increased hip flexion. FES increases dorsiflexor torque, improves toe clearance and dorsiflexion in swing phase, and significantly improves walking speed (p < 0.05). CONCLUSIONS: There are multiple causes of tripping in people with SP; FES reduces foot drop and improves walking speed.

BACKGROUND: An inflammatory component is present in the microenvironment of most neoplastic tissues. Inflammation and elevated C-reactive protein (CRP) are associated with poor prognosis and decreased survival in many types of cancer.Vitamin C has been suggested as having both a preventative and therapeutic role in a number of pathologies when administered at much higher-than-recommended dietary allowance levels.Since in vitro studies demonstrated inhibition of pro-inflammatory pathways by millimolar concentrations of vitamin C, we decided to analyze the effects of high dose IVC therapy in suppression of inflammation in cancer patients. METHODS: 45 patients with prostate cancer, breast cancer, bladder cancer, pancreatic cancer, lung cancer, thyroid cancer, skin cancer and B-cell lymphoma were treated at the Riordan Clinic by high doses of vitamin C (7.5 g -50 g) after standard treatments by conventional methods.CRP and tumor markers were measured in serum or heparin-plasma as a routine analysis. In addition, serum samples were collected before and after the IVCs for the cytokine kit tests. RESULTS: According to our data positive response to treatment, which was demonstrated by measurements of C- reactive protein, was found in 75% of patients and progression of the inflammation in 25% of patients. IVC treatments on all aggressive stage cancer patients showed the poor response of treatment.There was correlation between tumor markers (PSA, CEA, CA27.29 and CA15-3) and changes in the levels of C-reactive protein.Our test of the effect of IVC on pro-inflammatory cytokines demonstrated that inflammation cytokines IL-1α, IL-2, IL-8, TNF-α, chemokine eotaxin and CRP were reduced significantly after treatments. CONCLUSIONS: The high dose intravenous ascorbic acid therapy affects C-reactive protein levels and pro-inflammation cytokines in cancer patients. In our study, we found that modulation of inflammation by IVC correlated with decreases in tumor marker levels.In summary, our data support the hypothesis that high dose intravenous ascorbate treatments may reduce inflammation in cancer patients. Our results suggest that further investigations into the use of IVC to reduce inflammation in diseases where inflammation is relevant are warranted.

Boehringer Ingelheim's Automated Liquids Processing System (ALPS) in Ridgefield, Connecticut, was built to accommodate all compound solution-based operations following dissolution in neat DMSO. Process analysis resulted in the design of two nearly identical conveyor-based subsystems, each capable of executing 1400 × 384-well plate or punch tube replicates per batch. Two parallel-positioned subsystems are capable of independent execution or alternatively executed as a unified system for more complex or higher throughput processes. Primary ALPS functions include creation of high-throughput screening plates, concentration-response plates, and reformatted master stock plates (e.g., 384-well plates from 96-well plates). Integrated operations included centrifugation, unsealing/piercing, broadcast diluent addition, barcode print/application, compound transfer/mix via disposable pipette tips, and plate sealing. ALPS key features included instrument pooling for increased capacity or fail-over situations, programming constructs to associate one source plate to an array of replicate plates, and stacked collation of completed plates. Due to the hygroscopic nature of DMSO, ALPS was designed to operate within a 10% relativity humidity environment.

Calcific uremic arteriolopathy (calciphylaxis) is a devastating but rare complication seen predominantly in dialysis patients that often is fatal. Because of the rarity of the disease and the multifactorial nature of its cause, no clinical trials have been conducted to date to determine the best therapy for the condition. We report a case series of 7 patients at a single institution in whom a systematic multi-interventional treatment strategy was implemented, consisting of trigger-agent cessation (calcium-based phosphate binders, alphacalcidol, and warfarin), wound management, and antibiotic therapy, supplemented by intensified hemodialysis (4 hours daily for 7 days followed by 5-6 times weekly), intravenous sodium thiosulfate (12.5-25 g intravenously 3 times a week), and attempted oxygen therapy (given through a face mask or hyperbaric chamber as tolerated by patient circumstance). Treatments selected were based on literature review, consensus discussion, and attempts to address the physiologic disturbances that underlie the condition. All 7 patients identified with biopsy-proven calcific uremic arteriolopathy were treated with this regimen in 2007-2010, with 6 of 7 showing complete recovery. We suggest that consistent implementation of a multi-interventional approach may alter the course of this devastating disease. Further studies are needed to confirm and extend these findings.

BACKGROUND: Electrical stimulation of the upper extremity may reduce impairment in patients following stroke. Stimulation triggered on demand combined with task practice may be an effective means of promoting recovery of function. OBJECTIVE: The authors investigated the feasibility of using accelerometer-controlled electrical stimulation for the elbow, wrist, and finger extensors to enable functional task practice in patients with chronic hemiparesis. METHODS: Following a 4-week baseline, participants received 2 weeks of cyclic stimulation exercise to elbow and forearm extensor muscles, followed by 10 weeks of triggered stimulation to practice functional reaching. Participants were reassessed 12 weeks later as well. Outcome measures were the Action Research Arm Test (ARAT), Modified Ashworth Scale (MAS), Canadian Occupational Performance Measure (COPM), Psychosocial Impact of Assistive Devices Scale (PIADS), and Use of Device Questionnaire (UDQ). RESULTS: Fifteen volunteers who had at least 45° of forward shoulder flexion and could initiate elbow extension and grasp completed the study. The ARAT score improved from 19 to 32 (P = .002); the MAS score for elbow, wrist, and finger flexor spasticity was reduced from 2 each to 1, 0, and 1 (P < .05); the COPM performance and satisfaction scores improved (P = .001); and the PIADS became positive for competence (P = .005), adaptability (P = .008), and self-esteem (P = .008). Gains were maintained 12 weeks later. CONCLUSIONS: Accelerometer-triggered electrical stimulation to augment task training for the hemiplegic arm is feasible and may improve functional ability and quality of life which may be maintained 12 weeks after treatment. A randomized trial design is required to evaluate efficacy and cost benefit.
