Effect of short-term spinal orthosis and insoles application on cobb angle, plantar pressure and balance in individuals with adolescent idiopathic scoliosis.

BACKGROUND: Spinal orthosis applications are preferred for conservative treatment of adolescent idiopathic scoliosis, and holistic biomechanical approaches are recommended. METHODS: This was single-blind, prospective, randomized, controlled study. It included 42 patients (29 females/13 males) aged 10-18 years with adolescent idiopathic scoliosis, Cobb angle of 20°-45°, who were deemed suitable for spinal orthosis use. Patients were randomly divided into two groups: control, spinal orthosis group (n = 21), and insoles and spinal orthosis group (n = 21). All participants used spinal orthoses for 3 months. This study evaluated the functional capacities, quality of life, balance, and plantar pressures of the participants. The evaluations were repeated after 1 week, and 3 months following spinal orthosis application. FINDINGS: Statistically significant difference and positive effect were observed in Cobb angle (p = 0.008; p = 0.878, respectively), right total (p = 0.037; p = 0.193, respectively), left total (p = 0.037; p = 0.193, respectively), left rearfoot (p = 0.002; p = 0.708, respectively), and right forefoot plantar pressure (p = 0.001; p = 0.739, respectively) in participants in insoles and spinal orthosis group compared with those in the control group. Statistically significant differences and positive effects were observed in swing length (p = 0.001; p = 0.053, respectively) and functional capacity (p = 0.005; p = 0.220, respectively), which are parameters related to postural balance. No change was found in quality of life of either group (p > 0.05). INTERPRETATION: Insoles may have positive impact on functional capacity, balance, and plantar pressure during long-term follow-up in individuals with scoliosis. Therefore, the evaluation of foot plantar pressure in individuals with scoliosis is recommended, and personalized insoles may be a beneficial option.

Continuous real-time biofeedback in orthosis improves partial weight bearing on stairs.

INTRODUCTION: Climbing up and down stairs with crutches is a particular challenge. The current study evaluates a commercially available insole orthosis device for weighing an affected limb and for biofeedback training of gait. This study was done on healthy, asymptomatic individuals before applying to the intended postoperative patient. The outcomes should demonstrate whether a continuous real-time biofeedback (BF) system is more effective on stairs than the current protocol involving a bathroom scale. MATERIALS AND METHODS: 59 healthy test subjects received both crutches and an orthosis and learned to apply a 3-point gait with a partial load of 20 kg using a bathroom scale. Thereafter, the participants were asked to complete an up-and-down course, first without (control group) and then with (test group) an audio-visual real-time biofeedback (BF). Compliance was evaluated using an insole pressure measurement system. RESULTS: Using the conventional therapy technique, 36.6% of the steps up and 39.1% of the steps down in the control group were loaded with < 20 kg. By activating continuous biofeedback, steps with < 20 kg could be increased significantly to 61.1% upstairs (p < 0.001) and 66.1% downstairs (p < 0.001). All subgroups profited from the BF system, independent of age, gender, side relieved, dominant or non-dominant side. CONCLUSIONS: Traditional training without biofeedback led to poor performance for partial weight bearing on stairs, even among young and healthy individuals. However, continuous real-time biofeedback clearly improved compliance, indicating its potential to enhance training and support future research in patient populations.

A hybrid orthosis combining functional electrical stimulation and soft robotics for improved assistance of drop-foot.

Drop-foot is characterised by an inability to lift the foot, and affects an estimated 3 million people worldwide. Current treatment methods include rigid splints, electromechanical systems, and functional electrical stimulation (FES). However, these all have limitations, with electromechanical systems being bulky and FES leading to muscle fatigue. This paper addresses the limitations with current treatments by developing a novel orthosis combining FES with a pneumatic artificial muscle (PAM). It is the first system to combine FES and soft robotics for application to the lower limb, as well as the first to employ a model of their interaction within the control scheme. The system embeds a hybrid controller based on model predictive control (MPC), which combines FES and PAM components to optimally balance gait cycle tracking, fatigue reduction and pressure demands. Model parameters are found using a clinically feasible model identification procedure. Experimental evaluation using the system with three healthy subjects demonstrated a reduction in fatigue compared with the case of only using FES, which is supported by numerical simulation results.

Use of cast immobilization versus removable brace in adults with an ankle fracture: two-year follow-up of a multicentre randomized controlled trial.

The aim of this study was to compare the longer-term outcomes of operatively and nonoperatively managed patients treated with a removable brace (fixed-angle removable orthosis) or a plaster cast immobilization for an acute ankle fracture. This is a secondary analysis of a multicentre randomized controlled trial comparing adults with an acute ankle fracture, initially managed either by operative or nonoperative care. Patients were randomly allocated to receive either a cast immobilization or a fixed-angle removable orthosis (removable brace). Data were collected on baseline characteristics, ankle function, quality of life, and complications. The Olerud-Molander Ankle Score (OMAS) was the primary outcome which was used to measure the participant's ankle function. The primary endpoint was at 16 weeks, with longer-term follow-up at 24 weeks and two years. Overall, 436 patients (65%) completed the final two-year follow-up. The mean difference in OMAS at two years was -0.3 points favouring the plaster cast (95% confidence interval -3.9 to 3.4), indicating no statistically significant difference between the interventions. There was no evidence of differences in patient quality of life (measured using the EuroQol five-dimension five-level questionnaire) or Disability Rating Index. This study demonstrated that patients treated with a removable brace had similar outcomes to those treated with a plaster cast in the first two years after injury. A removable brace is an effective alternative to traditional immobilization in a plaster cast for patients with an ankle fracture.

Immediate effects of a buffered knee orthosis on gait in stroke patients with knee hyperextension.

BACKGROUND: Patients exhibit considerable variations in gait patterns especially in knee hyperextension in the stance phase after stroke. If knee hyperextension is untreated it may lead to pain, reduced independence in activities of daily living, deformities and instability. OBJECTIVE: The aim of this study was to investigate the immediate effects of a buffered knee orthosis on gait of stroke patients with knee hyperextension. METHODS: A total of nine patients with knee hyperextension after stroke were selected to wear buffered knee orthosis developed by Zhongshan Traditional Chinese Medicine Hospital and Ruike Medical Technology (Shanghai) Co., Ltd during walking training and daily walking. Then the gait analysis system of Motionanalysis was used to analyze and evaluate kinematic and spatiotemporal parameters of the gait in patients with independent walking or walking with a buffered knee orthosis. RESULTS: After wearing the buffered knee brace, initial contact, maximum and minimum angles of support phase, the toe off the ground, maximum and minimum angles of swing phase on the injured side of knee and ankle increased. Minimum angle of support phase and maximum angle of swing phase on the uninjured side of ankle decreased, while the toe off the ground and minimum angles of swing phase increased significantly (all P< 0.05); There was no significant difference in other kinematics, in parameters between time and space, in walking speed among subjective gait parameters (P> 0.05). Walking distance, confidence, sense of security, and the feeling of walking hyperextension were all improved. In addition, the number of asymmetric kinematic parameters and spatiotemporal parameters decreased. CONCLUSION: The buffered knee orthosis can effectively prevent knee hyperextension after stroke, improve the knee and ankle sagittal motion, gait asymmetry, gait subjective feeling, and does not affect gait space-time parameters.

Immediate Effect of Lumbosacral Orthosis and Abdominal Drawing-In Maneuver on Postural Control in Adults With Nonspecific Chronic Low Back Pain.

OBJECTIVE: The purpose of this study was to examine the immediate effects of lumbosacral orthosis and the abdominal drawing-in maneuver on the trunk postural control of adults with chronic low back pain compared with asymptomatic controls during 1-legged and semi-tandem stances. METHODS: An experimental and comparative study (cross-sectional design) was conducted in a laboratory setting. Twenty adults with chronic low back pain and 20 asymptomatic controls randomly performed 2 postural balance tasks over a force platform, considering 3 experimental conditions: (1) natural posture (baseline-control), (2) lumbosacral orthosis, and (3) abdominal drawing-in maneuver. Linear variables (mean amplitude, ellipse area, and sway velocity) derived from the center of pressure were computed, and 2-way analysis of variance (group × condition) for repeated measures were conducted. RESULTS: No group × condition interactions (.139 ≤ P ≤.938) were detected in any center of pressure parameters. No condition effect was detected, but a group effect (P = .042) was observed for 1 center of pressure parameter. The chronic low back pain group presented with a lower mean anteroposterior center of pressure amplitude than asymptomatic controls (∆ = 0.31 ± 0.66 cm [95% confidence interval, 0.05-0.56], P = .019) during the semi-tandem stance balance task. CONCLUSION: Neither lumbosacral orthosis nor the abdominal drawing-in maneuver showed immediate improvement in trunk postural control in any group. Thus, clinicians should not expect immediate benefits or improvements yielded by lumbosacral orthosis or the abdominal drawing-in maneuver when patients with chronic low back pain undergo these interventions.

Nonpharmacologic and Rehabilitative Strategies to Address Chronic Pain.

With benefits on pain and pain-related outcomes and low-risk profile, there has been an emphasis on nonpharmacologic management of chronic pain. Physical therapy uses exercises, manual therapies, and electrotherapy. Exercises include aerobic, strengthening, and flexibility exercises. Aquatic exercises have similar efficacy to land-based exercises. Multidisciplinary care uses a biopsychosocial approach. All are effective for pain-related outcomes. Occupational therapy focuses on ergonomics, joint protection, orthoses, and assistive devices. Limited evidence exists for taping, orthoses, assistive devices, thermotherapy, and education on pain-related outcomes. Weight loss in patients who are overweight or obese is effective for pain reduction in knee arthritis.

Patient Compliance With Wearing Lower Limb Assistive Devices: A Scoping Review.

OBJECTIVE: The aim of this scoping review was to identify information on compliance with wearing orthoses and other supportive devices, to discuss the barriers to adherence, and to suggest strategies for improvement based on these findings. METHODS: Online databases of PubMed, Web of Science, and the Cochrane Library were searched for articles about patients' compliance with regard to lower limb assistive devices. In addition, a methodological quality control process was conducted. Studies were included if in the English language and related to compliance and adherence to the lower limb assistive device. Exclusion was based on first reading the abstract and then the full manuscript confirming content was not related to orthotic devices and compliance. RESULTS: Twelve studies were included. The data revealed between 6% and 80% of patients were not using a prescribed device. Barriers to the use of the orthotic device included medical, functional, device properties and lack of proper fit. Strategies for improved compliance included better communication between patient and clinician, patient education, and improved comfort and device esthetics. CONCLUSIONS: Individualized orthotic adjustments, rehabilitation, and patient education were promising for increasing adherence. Despite positive aspects of improvements in gait, balance in elderly, and a sense of security produced by using assistive devices, compliance remains less than ideal due to barriers. As compliance in recent studies has not improved, continued work in this area is essential to realize the benefits of technological advances in orthotic and assistive devices.

Effect of Compression Therapy in the Treatment of Tibial Stress Syndrome in Military Service Members.

CONTEXT: Tibial stress syndrome (TSS) is an overuse injury of the lower extremities. There is a high incidence rate of TSS among military recruits. Compression therapy is used to treat a wide array of musculoskeletal injuries. The purpose of this study was to investigate the use of compression therapy as a treatment for TSS in military service members. DESIGN: A parallel randomized study design was utilized. METHODS: Military members diagnosed with TSS were assigned to either a relative rest group or compression garment group. Both groups started the study with 2 weeks of lower extremity rest followed by a graduated running program during the next 6 weeks. The compression garment group additionally wore a shin splints compression wrap during the waking hours of the first 2 weeks and during activity only for the next 6 weeks. Feelings of pain, TSS symptoms, and the ability to run 2 miles pain free were assessed at baseline, 4 weeks, and 8 weeks into the study. RESULTS: Feelings of pain and TSS symptoms decreased during the 8-week study in both groups (P < .05), but these changes were not significantly different between groups (P > .05). The proportion of participants who were able to run 2 miles pain free was significantly different (P < .05) between the 2 groups at the 8-week time point with the compression garment group having a significantly increased ability to complete the run without pain. CONCLUSIONS: Although perceptions of pain at rest were not different between groups, the functional ability of running 2 miles pain free was significantly improved in the compression garment group. These findings suggest that there is a moderate benefit to using compression therapy as an adjunct treatment for TSS, promoting a return to training for military service members.

Treatment of knee hyperextension in post-stroke gait. A systematic review.

BACKGROUND: Post-stroke, patients exhibit considerable variations in gait patterns. One of the variations that can be present in post-stroke gait is knee hyperextension in the stance phase. RESEARCH QUESTION: What is the current evidence for the effectiveness of the treatment of knee hyperextension in post-stroke gait? METHODS: MEDLINE, EMBASE, PEDro, CINAHL, and the Cochrane library were searched for relevant controlled trials. Two researchers independently extracted the data and assessed the methological quality. A best evidence synthesis was conducted to summarize the results. RESULTS: Eight controlled trials (5 RCTs, 3 CCTs) were included. Three types of interventions were identified: proprioceptive training, orthotic treatment, and functional electrostimulation (FES). In the included studies, the time since the stroke occurrence varied from the (sub)acute phase to the chronic phase. Only short-term effects were investigated. The adjustment from a form of proprioceptive training to physiotherapy training programs seems to be effective (moderate evidence) for treating knee hyperextension in gait, as applied in the subacute phase post-stroke. Neither evidence for effects on gait speed nor gait symmetry were found as a result of proprioceptive training. Orthoses that cover the knee have some effects (limited evidence) on knee hyperextension and gait speed. No evidence was found for FES. SIGNIFICANCE: This is the first systematic literature review on the effectiveness of interventions on knee hyperextension in post-stroke gait. We found promising results (moderate evidence) for some "proprioceptive approaches" as an add-on therapy to physiotherapy training programs for treating knee hyperextension during the subacute phase post-stroke, in the short-term. Therefore, initially, clinicians should implement a training program with a proprioceptive approach in order to restore knee control in these patients. Because only studies reporting short-term results were found, more high-quality RCTs and CCTs are needed that also study mid- and long-term effects.

[Physiotherapeutic and rehabilitative options for neuromuscular scolioses : Areas of physiotherapy techniques in the field of tension between hypertonic and hypotonic forms of neuromuscular scoliosis]. / Physiotherapeutische und rehabilitative Möglichkeiten bei neuromuskulären Skoliosen : Arbeitsfelder krankengymnastischer Techniken im Spannungsfeld hypertoner und hypotoner Formen neuromuskulärer Skoliosen.

Conservative treatment and physiotherapy (PT) of neuromuscular scoliosis and its underlying systemic causes is dominated by a pragmatic approach. In the choice of treatment, the observance of the underlying muscle tone sets the essential course to select an appropriate PT technique. Hypertonic forms need the reflex-modulation techniques included in Bobath or Vojta programmes. They sometimes necessitate tone-reducing medication and additional orthotics with a likely risk of pressure sores. In hypotonic forms of scoliosis on the other hand, gravity and spine collapse with pulmonal dysfunction are the key issues addressed by conservative treatment. Sustained quality of life and supported partaking in social life through maintenance of pulmonary function and upright sitting ability are of continuing concern. PT programmes with a neurophysiologic background such as those of Bobath and Vojta are of central significance.

Vertebral fracture during one repetition maximum testing in a breast cancer survivor: A case report.

RATIONALE: One repetition maximum (1-RM) testing is a standard strength assessment procedure in clinical exercise intervention trials. Because no adverse events (AEs) are published, expert panels usually consider it safe for patient populations. However, we here report a vertebral fracture during 1-RM testing. PATIENT CONCERNS: A 69-year-old breast cancer survivor (body-mass-index 31.6 kg/m2), 3 months after primary therapy, underwent 1-RM testing within an exercise intervention trial. At the leg press, she experienced pain accompanied by a soft crackling. DIAGNOSIS: Imaging revealed a partially unstable cover plate compression fracture of the fourth lumbar vertebra (L4) with a vertical fracture line to the base plate, an extended bone marrow edema and a relative stenosis of the spinal canal. INTERVENTIONS: It was treated with an orthosis and vitamin D supplementation. Another imaging to exclude bone metastases revealed previously unknown osteoporosis. OUTCOMES: The patient was symptom-free 6.5 weeks after the event but did not return to exercise. CONCLUSION: This case challenges safety of 1-RM testing in elderly clinical populations. LESSONS: Pre-exercise osteoporosis risk assessment might help reducing fracture risk. However, changing the standard procedure from 1-RM to multiple repetition maximum (x-RM) testing in studies with elderly or clinical populations would be the safest solution.

Telehealth in Pediatric Rehabilitation.

Pediatric rehabilitation focuses on optimizing function and quality of life of children through a holistic and transdisciplinary patient-centered team approach. This article describes the incorporation of telehealth in pediatric rehabilitation and its growth over the past decade. It also reviews the experience of practitioners using telehealth by necessity during the 2020 COVID-19 pandemic. Evidence suggests many applications where telehealth can appropriately substitute for traditional in-person visits, and there are many potential applications of telehealth to be explored as a means to enhance connectivity of the interdisciplinary rehabilitation team and the outreach to patients in remote and underserved areas.

Passive Knee Orthoses Assistance in Functional Electrical Stimulation Cycling in an Individual With Spinal Cord Injury.

Functional Electrical Stimulation (FES) may be used in rehabilitation and assistance of people with Spinal Cord Injury (SCI). One significant application is facilitating physical exercise, mainly when combining FES with mechanical platforms, such as tricycles. However, there are still technical challenges in FES cycling protocols, such as improving control and cycling performance. Here we show how passive elements in knee orthoses during FES cycling could increase the average cadence, taking advantage of the cycling movement. Our approach is twofold. First, we simulated the forward dynamics of a detailed musculoskeletal model with passive elements over the knees. Simulations showed that specific spring stiffness ranges increased the crankset speed during cycling by more than 50%. Using parameters found in simulations, we built a pair of passive orthoses and performed experiments with one individual with SCI. During two days, the volunteer cycled with similar stimulation magnitude with and without the passive elements. We observed that the average crankset speed was higher by more than 10% when the springs were attached to the passive orthoses. These results show the potential of using passive elements to increase cycling speed for FES cycling with similar or even lower stimulation magnitude, leading to longer exercise duration.

Rehabilitation regimen for non-surgical treatment of Achilles tendon rupture: A systematic review and meta-analysis of randomised controlled trials.

OBJECTIVES: To compare re-rupture rate, functional and quality-of-life outcomes, return to sports and work, complications, and resource use in patients treated non-surgically with different rehabilitation regimens for Achilles tendon rupture. DESIGN: Systematic review and meta-analysis. METHODS: We performed a systematic literature search in PubMed, Embase, Scopus and the Cochrane Library through May 2020 to identify randomized controlled trials (RCTs) that included patients treated non-surgically for Achilles tendon rupture. All analyses were stratified according to rehabilitation protocols. RESULTS: Eight RCTs with a total of 978 patients were included. There was no significant difference about re-rupture rate (P=0.38), return to sports (P=0.85) and work (P=0.33), functional outcome (P=0.34), quality of life (P=0.50), and complication rate (P=0.29) between early weight bearing with functional ankle motion and traditional ankle immobilisation with non-weight bearing. Similarly, no significant difference in re-rupture rate (P=0.88), return to sports (P=0.45) and work (P=0.20), functional outcome (P=0.26), and complication rate (P=0.49) was seen between ankle immobilisation with non-weight bearing and early weight bearing without functional ankle motion. CONCLUSIONS: Traditional ankle immobilisation with non-weight bearing was not found to be superior to early weight bearing with or without functional ankle motion for patients treated non-surgically for Achilles tendon rupture. Clinicians may consider early weight bearing in functional brace as a safe and cost-effective alternative to non-weight bearing with plaster casting.

The Effect of Scapular Muscle Strengthening on Functional Recovery in Patients With Lateral Elbow Tendinopathy: A Pilot Randomized Controlled Trial.

CONTEXT: There is a lack of consensus on the best management approach for lateral elbow tendinopathy (LET). Recently, scapular stabilizer strength impairments have been found in individuals with LET. OBJECTIVE: The purpose of this study was to compare the effectiveness of local therapy (LT) treatment to LT treatment plus a scapular muscle-strengthening (LT + SMS) program in patients diagnosed with LET. DESIGN: Prospective randomized clinical trial. SETTING: Multisite outpatient physical therapy. PATIENTS: Thirty-two individuals with LET who met the criteria were randomized to LT or LT + SMS. INTERVENTIONS: Both groups received education, a nonarticulating forearm orthosis, therapeutic exercise, manual therapy, and thermal modalities as needed. Additionally, the LT + SMS group received SMS exercises. MAIN OUTCOME MEASURE: The primary outcome measure was the patient-rated tennis elbow evaluation; secondary outcomes included global rating of change (GROC), grip strength, and periscapular muscle strength. Outcomes were reassessed at discharge, 6, and 12 months from discharge. Linear mixed-effect models were used to analyze the differences between groups over time for each outcome measure. RESULTS: The average duration of symptoms was 10.2 (16.1) months, and the average total number of visits was 8.0 (2.2) for both groups. There were no significant differences in gender, age, average visits, weight, or height between groups at baseline (P > .05). No statistical between-group differences were found for any of the outcome measures. There were significant within-group improvements in all outcome measures from baseline to all follow-up points (P < .05). CONCLUSION: The results of this pilot study suggest that both treatment approaches were equally effective in reducing pain, improving function, and increasing grip strength at discharge as well as the 6- and 12-month follow-ups. Our multimodal treatment programs were effective at reducing pain and improving function up to 1 year after treatment in a general population of individuals with LET.

Trends and Technologies in Rehabilitation of Foot Drop: A Systematic Review.

INTRODUCTION: Foot Drop (FD) is a condition, which is very commonly found in post-stoke patients; however it can also be seen in patients with multiple sclerosis, and cerebral palsy. It is a sign of neuromuscular damage caused by the weakness of the muscles. There are various approaches of FD's rehabilitation, such as physiotherapy, surgery, and the use of technological devices. Recently, researchers have worked on developing various technologies to enhance assisting and rehabilitation of FD. AREAS COVERED: This review analyzes different types of technologies available for FD. This include devices that are available commercially or still under research. 101 studies published between 2015 and 2020 were identified for the review, many were excluded due to various reasons, e.g., were not robot-based devices, did not include FD as one of the targeted diseases, or was insufficient information. 24 studies that met our inclusion criteria were assessed. These studies were further classified into two different categories: robot-based ankle-foot orthosis (RAFO) and Functional Electrical Stimulation (FES) devices. EXPERT OPINION: Studies included showed that both RAFO and FES showed considerable improvement in the gait cycle of the patients. Future trends are inclining towards integrating FES with other neuro-concepts such as muscle-synergies for further developments.

Electromechanical-assisted training for walking after stroke.

BACKGROUND: Electromechanical- and robot-assisted gait-training devices are used in rehabilitation and might help to improve walking after stroke. This is an update of a Cochrane Review first published in 2007 and previously updated in 2017. OBJECTIVES: Primary • To determine whether electromechanical- and robot-assisted gait training versus normal care improves walking after stroke Secondary • To determine whether electromechanical- and robot-assisted gait training versus normal care after stroke improves walking velocity, walking capacity, acceptability, and death from all causes until the end of the intervention phase SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (last searched 6 January 2020); the Cochrane Central Register of Controlled Trials (CENTRAL; 2020 Issue 1), in the Cochrane Library; MEDLINE in Ovid (1950 to 6 January 2020); Embase (1980 to 6 January 2020); the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to 20 November 2019); the Allied and Complementary Medicine Database (AMED; 1985 to 6 January 2020); Web of Science (1899 to 7 January 2020); SPORTDiscus (1949 to 6 January 2020); the Physiotherapy Evidence Database (PEDro; searched 7 January 2020); and the engineering databases COMPENDEX (1972 to 16 January 2020) and Inspec (1969 to 6 January 2020). We handsearched relevant conference proceedings, searched trials and research registers, checked reference lists, and contacted trial authors in an effort to identify further published, unpublished, and ongoing trials. SELECTION CRITERIA: We included all randomised controlled trials and randomised controlled cross-over trials in people over the age of 18 years diagnosed with stroke of any severity, at any stage, in any setting, evaluating electromechanical- and robot-assisted gait training versus normal care. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion, assessed methodological quality and risk of bias, and extracted data. We assessed the quality of evidence using the GRADE approach. The primary outcome was the proportion of participants walking independently at follow-up. MAIN RESULTS: We included in this review update 62 trials involving 2440 participants. Electromechanical-assisted gait training in combination with physiotherapy increased the odds of participants becoming independent in walking (odds ratio (random effects) 2.01, 95% confidence interval (CI) 1.51 to 2.69; 38 studies, 1567 participants; P < 0.00001; I² = 0%; high-quality evidence) and increased mean walking velocity (mean difference (MD) 0.06 m/s, 95% CI 0.02 to 0.10; 42 studies, 1600 participants; P = 0.004; I² = 60%; low-quality evidence) but did not improve mean walking capacity (MD 10.9 metres walked in 6 minutes, 95% CI -5.7 to 27.4; 24 studies, 983 participants; P = 0.2; I² = 42%; moderate-quality evidence). Electromechanical-assisted gait training did not increase the risk of loss to the study during intervention nor the risk of death from all causes. Results must be interpreted with caution because (1) some trials investigated people who were independent in walking at the start of the study, (2) we found variation between trials with respect to devices used and duration and frequency of treatment, and (3) some trials included devices with functional electrical stimulation. Post hoc analysis showed that people who are non-ambulatory at the start of the intervention may benefit but ambulatory people may not benefit from this type of training. Post hoc analysis showed no differences between the types of devices used in studies regarding ability to walk but revealed differences between devices in terms of walking velocity and capacity. AUTHORS' CONCLUSIONS: People who receive electromechanical-assisted gait training in combination with physiotherapy after stroke are more likely to achieve independent walking than people who receive gait training without these devices. We concluded that eight patients need to be treated to prevent one dependency in walking. Specifically, people in the first three months after stroke and those who are not able to walk seem to benefit most from this type of intervention. The role of the type of device is still not clear. Further research should consist of large definitive pragmatic phase 3 trials undertaken to address specific questions about the most effective frequency and duration of electromechanical-assisted gait training, as well as how long any benefit may last. Future trials should consider time post stroke in their trial design.

Physical therapy for tendinopathy: An umbrella review of systematic reviews and meta-analyses.

OBJECTIVE: To summarize evidence in the last decade regarding the efficacy of physical therapy interventions to treat tendinopathy, as a single disease entity, as determined in systematic reviews (SRs) and/or meta-analyses (MAs). METHODS: Electronic search of PubMed, PEDro, and Scopus database was performed from year 2010 to January 2020. The methodological quality of the identified studies was assessed using the AMSTAR 2 tool. Studies scoring 9 points or higher were further analyzed using GRADE principles. RESULTS: 40 SRs and/or MAs were included in qualitative synthesis, whereas only 5 MAs were included in quantitative synthesis. Low-level laser therapy (LLLT) intervention showed a pooled improvement in pain reduction of 1.53 cm; 95% CI, [1.14, 1.91] (I2 = 1.9%, p = 0.361) on visual analogue scale, and grip strength of 9.59 kg; 95% CI, [5.90, 13.27]. CONCLUSIONS: Moderate-quality evidence may support these following interventions: LLLT revealed a statistically and potentially clinically significant improvement in pain and function on the short-term. Extracorporeal shockwave therapy showed a statistically significant enhancement in pain and function at all follow-up durations; however, its clinical significance was undetermined. Eccentric exercise was supported by qualitative evidence only. Caution is advised when interpreting results due to possible pathological differences in tendinopathy at each region.

The Effect of the Powerball Gyroscope as a Treatment Device for Nonspecific Wrist Pain.

OBJECTIVE: The aim of this study was to determine the effect of using the Powerball gyroscope as a treatment device on pain and change in endurance in nonspecific wrist pain. METHODS: This study was a within-participants pre- and postintervention study consisting of 40 participants between ages 18 and 35 with an equal male-to-female ratio. The participants used the Powerball gyroscope for 5 minutes per treatment session. Treatment comprised 12 sessions carried out 3 × per week over a 4-week period. Participants completed objective and subjective data before the first, seventh, and 12th sessions. Objective data were recorded using the Jamar dynamometer to measure grip strength. Subjective data were gathered using the Patient-Rated Wrist Evaluation Questionnaire. Participants then used the Powerball gyroscope in the hand with the affected wrist. The Wilcoxon signed rank test and 1-way repeated-measures analysis of variance were used to analyze the changes. RESULTS: A significant decrease in pain was noted throughout the study, but the most significant changes occurred between the seventh and 12th treatment sessions (P < .01). A significant increase in grip strength was also noted throughout the study, with the greater increase in grip strength occurring during the first 7 treatments (P < .02). CONCLUSION: The Powerball gyroscope showed a change in outcome regarding nonspecific wrist pain and grip strength.
