Modified Constraint-Induced Movement Therapy Versus Traditional Rehabilitation in Patients With Upper-Extremity Dysfunction After Stroke: A Systematic Review and Meta-Analysis

High-frequency magnetic paired associated stimulation promotes motor function recovery in ischemic stroke patients: a study protocol for single-center, sham stimulation randomized controlled trials (H2MPAS)

BACKGROUND

Numerous studies have validated the clinical effectiveness of electromagnetic pairing-associated stimulation. Building upon this foundation, we have developed a novel approach involving high-frequency magnetic paired-associated stimulation, aiming to enhance clinical applicability and potentially improve efficacy. However, the clinical effectiveness of this approach remains unclear. Our objective is to demonstrate the therapeutic efficacy of this novel approach by employing high-frequency pairing to intervene in patients experiencing motor dysfunction following a stroke.

METHODS

This is a single-center, single-blind, sham stimulation controlled clinical trial involving patients with upper limb motor dysfunction post-stroke. The intervention utilizes paired magnetic stimulation, combining peripheral and central magnetic stimulation, in patients with Brunnstrom stage III-V stroke lasting from 3 months to 1 year. Evaluation of patients' upper limb motor function occurred before the intervention and after 3 weeks of intervention. Follow-up visits will be conducted after 5 weeks and 3 months of intervention. The primary outcome measure is the Action Research Arm Test, with secondary measures including the Fugl-Meyer Assessment-upper, Modified Barthel Index, modified Tardieu scale, functional near-infrared spectroscopy, and neuroelectrophysiology.

DISCUSSION

The high-frequency magnetic paired associative stimulation used in this study combined high-frequency magnetic stimulation with paired stimulation, potentially facilitating both cortical excitation through high-frequency stimulation and specific circuit enhancement through paired stimulation. As dual-coil magnetic stimulation equipment becomes increasingly popular, magnetic-magnetic paired associated stimulation may offer patients improved clinical outcomes at reduced costs.

This paper provides a thorough exploration of rehabilitation strategies in stroke management, focusing on diagnostic methods, acute management, and diverse modalities encompassing physical, occupational, speech, and cognitive therapies. Emphasizing the importance of early identification of rehabilitation needs and leveraging technological advancements, including neurostimulation techniques and assistive technologies, this manuscript highlights the challenges and opportunities in stroke rehabilitation. Additionally, it discusses future directions, such as personalized rehabilitation approaches, neuroplasticity concepts, and advancements in assistive technologies, which hold promise in reshaping the landscape of stroke rehabilitation. By delineating these multifaceted aspects, this manuscript aims to provide insights and directions for optimizing stroke rehabilitation practices and enhancing the quality of life for stroke survivors.

Bottom-up versus Top-down designed rehabilitation sessions in chronic stroke survivors: a pilot randomized controlled trial

PURPOSE

The present study aimed to compare the effectiveness of Top-down and Bottom-up approaches on levels of the International Classification of Functioning, Disability and Health Framework (ICF), including impairments, activities, and participation.

MATERIALS AND METHODS

Thirty-nine chronic stroke survivors were recruited for this single-blinded randomized clinical trial. Participants were assigned to Top-down, Bottom-up interventions, or control group, and received a 6-week intervention. They were assessed before/after treatments and at follow-up (6 weeks later). Impairments were measured through kinematic analysis, Trail Making Tests (TMT), and Fugl-Meyer Assessment (FMA). Activity and participation were evaluated via Box and Block Test, Motor Activity Log (MAL), and Canadian Occupational Performance Measure (COPM), respectively.

RESULTS

We found significant improvements in impairment (FMA) and participation (COPM) in all groups, however, COPM scores improved beyond the MCID only in the Top-down, and FMA scores exceeded the MCID in Top-down and Bottom-up groups. Use of the upper limb in daily activities (MAL) enhanced in the Top-down group, although was not clinically significant.

CONCLUSION

In most of the outcome measures, no significant difference was observed between groups. It seems that Top-down, Bottom-up, and traditional interventions have relatively comparable effectiveness in chronic stroke survivors.

Effectiveness of constraint-induced movement therapy (CIMT)-Telerehabilitation compared to traditional CIMT on upper extremity dysfunction of adult chronic stroke patients-A systematic review and meta-analysis

BACKGROUND/OBJECTIVE

Constraint-induced movement therapy (CIMT), a therapy that encourages the use of the affected upper limb through intensive functional tasks, effectively promotes upper limb function in patients with chronic stroke. This study determined the effectiveness of CIMT using telerehabilitation compared with traditional CIMT in improving mild to moderate upper limb motor function in adult patients with chronic stroke.

METHODS

Eligible studies were identified by searching electronic databases and scanning the reference lists of articles. Review Manager 5.4 was used to determine the pooled mean effect size of the standardized mean difference and 95% confidence interval for the group comparison. Visual heterogeneity, I2 statistic, and chi-square test were used to measure the heterogeneity between the included studies. We evaluated the quality of evidence using GRADEpro GDT, software for creating evidence summaries and healthcare recommendations.

RESULTS

Two randomized controlled trials were included in this review. A total of 109 participants (70 male, 39 female) were evaluated. The time since the stroke was ≥6 months in one study and ≥1 year in another study. Improvements in upper limb motor function while performing functional movements were measured using the Wolf Motor Function Test. The evidence for the effectiveness of CIMT using telerehabilitation compared with traditional CIMT in improving the upper extremity function in patients with chronic stroke is of moderate quality. This suggests no significant difference between the groups (mean difference [95% CI]: -0.04 [-0.42, 0.33]).

CONCLUSIONS

CIMT using telerehabilitation is not superior to traditional CIMT in improving patients' upper extremity motor function with chronic stroke. CIMT using telerehabilitation may improve access to treatment, minimize SARS-CoV-2 risk, and reduce travel in patients with chronic stroke.

Effects of modified-constraint induced movement therapy based telerehabilitation on upper extremity motor functions in stroke patients

INTRODUCTION

The aim of this study is to investigate the effects of Modified-Constraint Induced Movement Therapy (m-CIMT) based telerehabilitation on upper extremity motor functions in stroke patients.

METHODS

Eighteen stroke patients were included and randomly allocated into two groups. The Tele-CIMT (modified-constraint induced movement therapy-based telerehabilitation) (n = 10) group received m-CIMT based telerehabilitation for 90 min a day, 5 weekdays for 3 weeks at home. Additionally, both the Tele-CIMT group and the control group (CG) (n = 8) underwent the home exercise program aimed at improving range of motion, active movement, balance, and walking every weekday for 3 weeks at home. The outcome measures were the Stroke Rehabilitation Assessment of Movement Scale (STREAM), Fugl-Meyer Upper Extremity Motor Evaluation Scale (FM-UE), Wolf Motor Function Test (WMFT), 9-Hole Peg Test (9-HPT), grip strengths, pinch strengths, Motor Activity Log-28 (MAL-28), and Functional Independence Measure (FIM).

RESULTS

Significant group-by-time interactions on STREAM, FM-UE, WMFT, grip strength, pinch strengths, MAL-28, and FIM were found to be in favor of the Tele-CIMT group. Additionally, post hoc analyses revealed that the Tele-CIMT group significantly improved in terms of these parameters (p > .05).

CONCLUSION

This is the first randomized controlled trial showing that Tele-CIMT improved upper extremity motor functions and activities of daily living in stroke patients. Tele-CIMT can help improve the upper extremities in stroke survivors who have difficulties reaching rehabilitation clinics.

Effect of a restrictive orthosis on the paralyzed hand in combination with constraint-induced movement therapy in a patient with chronic stroke: a case report

PURPOSE

Many studies have reported the effects of constraint-induced movement therapy (CIMT) with an orthosis on the residual function of the impaired side of post-stroke patients. We encountered a case with left hemiparesis whose functioning of the impaired hand improved by CIMT with an orthosis not to assist as in the past but to restrict the residual function of the paralyzed fingers.

METHODS

The patient was a 46-year-old woman with left hemiparesis due to cerebral infarction 18 months ago. The patient had resumed work but would easily tire while typing the keyboard. We found that the extrinsic hand muscles were more engaged in compensatory movements than the intrinsic muscles. Therefore, we designed an orthosis that would extend and fixation the distal interphalangeal joint and proximal interphalangeal joint muscles to promote the engagement of the intrinsic muscles and restrict the compensatory movements of the extrinsic muscles.

RESULTS

The orthosis was used for 8 h/day for 2 weeks; CIMT were performed. Left hemiplegia improved from CIMT and the patient was able to handle the same amount of work as that before onset.

CONCLUSION

Restrictive orthosis on the paralyzed hand in combination with CIMT was found to be a beneficial rehabilitation approach.

Modified-constraint movement induced therapy versus neuro-developmental therapy on reaching capacity in children with hemiplegic cerebral palsy

BACKGROUND AND OBJECTIVE

Upper extremity impairment is one of the complications in hemiplegic children. The purpose of modified constraint-induced movement therapy (mCIMT) is to improve the function of impaired arms and hands in these children. This study compared the efficacy of mCIMT and the approach of neurodevelopmental therapy (NDT) on reaching capacity in children with spastic hemiplegia.

METHODS

Fifty-two spastic hemiplegic children ranging in age from four to 6 years were selected for this study from an outpatient clinic and biomechanical lab (Prince Sattam bin Abdulaziz University, KSA). They were randomly divided into two experimental groups: group I received NDT and group II received mCIMT for the involved upper limb and restriction of the uninvolved arm movements for 12 weeks (three times per week). Both groups received a conventional exercise program in addition to experimental one. Active elbow extension range of motion and three-dimensional motion analysis of the reaching task were measured before and after 3 months of treatment.

RESULTS

Significant enhancement in all pre-treatment and post-treatment outcomes was observed in both groups by a two-way mixed MANOVA; furthermore, Group II (mCIMT) showed the most significant improvement (elbow extension, percentage of reach to peak velocity, movement time and movement units) when comparing the post-treatment outcomes between the two groups (p < 0.001).

IMPLICATION FOR PHYSIOTHERAPY PRACTICE

Addition of mCIMT to a conventional exercise was superior to adding NDT exercise therapy in promoting the performance of reaching pattern in hemiplegic children.

An Exploration of the Effectiveness of Different Intensity Protocols of Modified Constraint-Induced Therapy in Stroke: A Systematic Review

Purpose

To examine the effectiveness of different modified Constraint-Inuced Therapy (mCIMT) protocol intensities on upper extremity motor function in adults with hemiplegia.

Methods

A search was conducted in PubMed, Scopus, EBSCO, and Cochrane Library for articles published between April 2010 and December 2021. Only randomized controlled trials (RCTs) were included. Studies were excluded if they used a sample of less than five, mCIMT in combination with other therapy, and/or if they were not written in English. Methodologic quality was assessed using the Cochrane collaboration risk of bias tool-2.

Results

Thirty-six RCTs with a total of 721 participants were included. Most researchers followed a moderate to low protocol intensity in terms of total treatment time and moderate to high intensity with regard to restriction time. Almost all of the upper limb motor function measures showed statistically significant improvements (p < .05) after mCIMT, irrespective of the protocol's intensity, but there was lack of high-quality studies. Statistically significant improvements did not always translate to clinical importance.

Conclusions

Low-intensity CIMT protocols may result in comparable improvements to more intensive ones but caution has to be taken when drawing conclusions due to high risk of bias studies.

Timing and Dose of Constraint-Induced Movement Therapy after Stroke: A Systematic Review and Meta-Regression

The aim of this study is to investigate the effects of constraint-induced movement therapy on stroke patients who had intact cognition and some voluntary finger extension and to identify optimal protocols to apply this therapy method. We searched PubMed, Cochrane Library, and Embase for randomized controlled trials conducted prior to January 2022. The outcomes included the Motor Activity Log, Fugl-Meyer Assessment, and Wolf Motor Function Test. The inverse variance method fixed-effect model as well as the DerSimonian and Laird estimator random-effects model were applied, and the mean difference was calculated with 95% confidence interval to measure continuous outcomes. Six randomized controlled trials involving a total of 169 patients with stroke were enrolled. Compared with conventional rehabilitation methods, there was no significant effect of constraint-induced movement therapy when evaluated by the Motor Activity Log, including the amount of use (random-effect, standardized mean difference 0.65; 95%, confidence interval: −0.23–1.52) and quality of movement (random-effect, standardized mean difference 0.60; 95% confidence interval: −0.19–1.39). However, among patients with chronic stroke symptoms, meta-regression analyses showed better performance with a constraint time of at least 6 h per day and 6 h training per week when assessing the amount of use (p = 0.0035) and quality of movement (p = 0.0031). Daily intervention time did not lead to a significant difference in functional upper limb performance. An efficient protocol of constraint-induced movement therapy designed as 6 h of training per week with 6 h constraint per day could bring significant stroke symptom improvement to patients with chronic stroke.

The effect and safety of constraint-induced movement therapy for post-stroke motor dysfunction: a meta-analysis and trial sequential analysis

Background

Due to motor function insufficiency, patients with post-stroke motor dysfunction (PSMD) have limitations in performing an activity, feel restricted during social participation, and feel impaired in their quality of life. Constraint-induced movement therapy (CIMT) is a neurorehabilitation technique, but its effectiveness on PSMD after stroke still remains controversial.

Objective

This meta-analysis and trial sequential analysis (TSA) aimed to comprehensively evaluate the effect and safety of CIMT for PSMD.

Methods

Four electronic databases were searched from their inception to 1 January 2023 to identify randomized controlled trials (RCTs) investigating the effectiveness of CIMT for PSMD. Two reviewers independently extracted the data and assessed the risk of bias and reporting quality. The primary outcome was a motor activity log for the amount of use (MAL-AOU) and the quality of movement (MAL-QOM). RevMan 5.4, Statistical Package for Social Sciences (SPSS) 25.0, and STATA 13.0 software were used for statistical analysis. The certainty of the evidence was appraised using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. We also performed the TSA to assess the reliability of the evidence.

Results

A total of 44 eligible RCTs were included. Our results showed that CIMT combined with conventional rehabilitation (CR) was superior to CR in improving MAL-AOU and MAL-QOM scores. The results of TSA indicated that the above evidence was reliable. Subgroup analysis demonstrated that CIMT (≥6 h per day or duration ≤ 20 days) combined with CR was more effective than CR. Meanwhile, both CIMT and modified CIMT (mCIMT) combined with CR were more efficient than CR at all stages of stroke. No severe CIMT-related adverse events occurred.

Conclusion

CIMT may be an optional and safe rehabilitation therapy to improve PSMD. However, due to limited studies, the optimal protocol of CIMT for PSMD was undetermined, and more RCTs are required for further exploration.

Eylem Gözlem Terapisi ile Unilateral Serebral Palsili Çocuklarda Üst Ekstremite Fonksiyonelliğinin Geliştirilmesi

Eylem Gözlem Terapisi (EGT) hareketlerin izlenmesi sonrası aynı hareketlerin taklit edilmesi ile merkezi sinir sistemi restorasyonunu destekleyen nörorehabilitasyon temelli bir tedavi yaklaşımıdır. Serebral palsi, parkinson, inme, ortopedik yaralanmalar, alzheimer ve konuşma bozuklukları gibi pek çok hastalıkta, fonksiyonu gerçekleştiren nöral yapıları aktive etmek için nörofizyolojik mekanizmadan yararlanan yeni bir rehabilitasyon yaklaşımı olarak bilinir. Sağlıklı bireylerde ve nörolojik veya ortopedik etkilenimi olan bireylerde yapılan araştırmalar; EGT uygulamasının gözlemcinin motor sisteminde kolaylaştırmayı indüklediği ve eylem-algı eşleştirme mekanizmasını desteklediği bilinir. Bu derleme, Serebral Palsi (SP) tanılı çocuklarda üst ekstremiteye yönelik uygulanan EGT programlarının kullanımı ve etkinliği ile ilgili mevcut bilgileri gözden geçirmek amacıyla planlanmıştır. EGT kullanımının farklı koşullara kolayca adapte edilebilmesi, nöral plasitisiteyi destekleyerek motor öğrenmeyi fasilite etmesi ve ekonomik olması nedeniyle, SP’li çocukların üst ekstremite rehabilitasyonunda kullanımının uygun olduğu; ancak protokol, süre ve uygulama şekli açısından optimal uygulama prensiplerinin belirlenebilmesi için daha detaylı çalışmalara ihtiyaç olduğu düşünülmektedir.

Comparison of the Effects of Constraint-Induced Movement Therapy and Unconstraint Exercise on Oxidative Stress and Limb Function-A Study on Human Patients and Rats with Cerebral Infarction

Most conventional post-stroke rehabilitation treatments do not involve imposed constraints of the unaffected limb. In contrast, Constraint-Induced Movement Therapy (CIMT) is comprised of massed task practice with the affected limb and constraint of the unaffected limb. CIMT is a promising rehabilitation technique used for motor recovery of affected limbs after stroke, but its effectiveness and mechanism are not fully understood. We compared the effects of the two exercise modes on limb function post-stroke in animal models and human subjects, and investigated whether oxidative stress response was involved in regulating the effects. We first conducted a randomized controlled trial (RCT), in which 84 subjects with cerebral infarction were assigned to dose-matched constraint-induced movement therapy (CIMT), or unconstraint exercise (UE), or conventional rehabilitation treatment. Motor functions of the limb are primary outcomes of the RCT measured using Brief Fugl-Meyer upper extremity score (FMA-UE), Ashworth score, and Barthel scale. Psychological influence of CIMT and UE was also examined using Self-Rating Depression Scale (SDS). Next, we investigated the effects of CIMT and UE in rats undergoing middle cerebral artery occlusion and reperfusion (MCAO/R). Motor function, infarct volume, and pathohistological changes were investigated by mNSS, MRI, and histological studies. The role of Keap1-Nrf2-ARE was investigated using qRT-PCR, Western blot, immunochemistry, immunofluorescence, and ELISA experiments. In RCT, patients taking CIMT had a higher score in FMA-UE, Barthel index, and SDS, and a lower score in modified Ashworth, compared to those taking UE. In rats receiving CIMT, motor function was increased, and infarct volume was decreased compared to those receiving UE. The expression of Keap1 protein and mRNA in the peri-infarct tissue was decreased, and Nrf2 and ARE protein and mRNA were increased in rats receiving CIMT compared with UE. Nrf2 agonist t-BHQ increased the benefits of CIMT. In conclusion, CIMT is more effective than UE in improving upper limb motor function, reducing muscle spasm in patients with cerebral infarction compared to UE, but patients receiving CIMT may feel depressed. Moreover, both CIMT and UE are beneficial to limb function recovery and limit the infarct expansion in MCAO/R rats, but CIMT was more effective than UE. Oxidative stress reaction has an essential role in regulating the CIMT induced benefits.

Network Meta-Analysis of Non-Conventional Therapies for Improving Upper Limb Motor Impairment Poststroke

BACKGROUND

Network meta-analysis is a method that can estimate relative efficacy between treatments that may not have been compared directly within the literature. The purpose of this study is to present a network meta-analysis of non-conventional interventions to improve upper extremity motor impairment after stroke.

METHODS

A literature search was conducted in 5 databases from their inception until April 1, 2021. Terms were used to narrow down articles related to stroke, the upper extremity, and interventional therapies. Randomized controlled trials written in English were eligible if; 50% poststroke patients; ≥18 years old; applied an intervention for the upper extremity, and/or used the Fugl-Meyer upper extremity scale as an outcome measure; the intervention had ≥3 randomized controlled trials with comparisons against a conventional care group; conventional care groups were dose matched for therapy time. A Bayesian network meta-analysis approach was taken to estimate mean difference (MD) and 95% CI.

RESULTS

One hundred seventy-six randomized controlled trials containing 6781 participants examining 20 non-conventional interventions were identified for inclusion within the final model. Eight of the identified interventions proved significantly better than conventional care, with modified constraint induced movement therapy (MD, 6.7 [95% CI, 4.3-8.9]), high frequency repetitive transcranial magnetic stimulation (MD, 5.4 [95% CI, 1.9-8.9]), mental imagery (MD, 5.4 [95% CI, 1.8-8.9]), bilateral arm training (MD, 5.2 [95% CI, 2.2-8.1]), and intermittent theta-burst stimulation (MD, 5.1 [95% CI, 0.62-9.5]) occupying the top 5 spots according to the surface under the cumulative ranking curve.

CONCLUSIONS

Overall, it would seem that modified constraint induced movement therapy has the greatest probability of being the most effective intervention, with high-frequency repetitive transcranial magnetic stimulation, mental imagery, and bilateral arm training all having similar probabilities of occupying the next spot in the rankings. We think this analysis can provide a guide for where future resources and clinical trials should be directed, and where a clinician may begin when considering alternative therapeutic interventions.

Effect of Transcranial Direct Current Stimulation Augmented with Motor Imagery and Upper-Limb Functional Training for Upper-Limb Stroke Rehabilitation: A Prospective Randomized Controlled Trial

BACKGROUND

Combining transcranial direct current stimulation (tDCS) with other therapies is reported to produce promising results in patients with stroke. The purpose of the study was to determine the effect of combining tDCS with motor imagery (MI) and upper-limb functional training for upper-limb rehabilitation among patients with chronic stroke.

METHODS

A single-center, prospective, randomized controlled trial was conducted among 64 patients with chronic stroke. The control group received sham tDCS with MI, while the experimental group received real tDCS with MI. Both groups performed five different upper-limb functional training exercises coupled with tDCS for 30 min, five times per week for two weeks. Fugl-Meyer's scale (FMA) and the Action Research Arm Test (ARAT) were used to measure the outcome measures at baseline and after the completion of the 10th session.

RESULTS

Analysis of covariance showed significant improvements in the post-test mean scores for FMA (F (414.4) = 35.79, p < 0.001; η² = 0.37) and ARAT (F (440.09) = 37.46, p < 0.001; η² = 0.38) in the experimental group compared to the control group while controlling for baseline scores.

CONCLUSIONS

Anodal tDCS stimulation over the affected primary motor cortex coupled with MI and upper-limb functional training reduces impairment and disability of the upper limbs among patients with chronic stroke.

A novel sensor-embedded holding device for monitoring upper extremity functions

There are several causes that can lead to functional weakness in the hands or upper extremities (UE), such as stroke, trauma, or aging. Therefore, evaluation and monitoring of UE rehabilitation have become essential. However, most traditional evaluation tools (TETs) and assessments require clinicians to assist or are limited to specific clinical settings. Several novel assessments might apply to wearable devices, yet those devices will still need clinicians or caretakers to help with further tests. Thus, a novel UE assessment device that is user-friendly and requires minimal assistance would be needed. The cylindrical grasp is one of the common UE movements performed in daily life. Therefore, a cylindrical sensor-embedded holding device (SEHD) for training and monitoring was developed for a usability test within this research. The SEHD has 14 force sensors with an array designed to fit holding positions and a six-axis inertial measurement unit (IMU) to monitor grip strength, hand dexterity, acceleration, and angular velocity. Six young adults, six healthy elderly participants, and three stroke survivors had participated in this study to see if the SEHD could be used as a reference to TETs. During result analyses, where the correlation coefficient analyses were applied, forearm rotation smoothness and the Purdue Pegboard Test (PPT) showed a moderate negative correlation [r (16) = −0.724, p < 0.01], and the finger independence showed a moderate negative correlation with the PPT [r (10) = −0.615, p < 0.05]. There was also a highly positive correlation between the maximum pressing task and Jamar dynamometer in maximum grip strength [r (16) = 0.821, p < 0.01]. These outcomes suggest that the SEHD with simple movements could be applied as a reference for users to monitor their UE ability.

Proprioceptive based training or modified constraint-induced movement therapy on upper extremity motor functions in chronic stroke patients: A randomized controlled study

BACKGROUND: The Modified Constraint-Induced Movement Therapy (mCIMT) method is a unilateral training that respectively avoids and activates less affected and affected sides of upper extremities; however, the selected options are not typically ideal. Proprioceptive based training (PT) includes bilateral training methods and influencing proprioceptive receptors. OBJECTIVE: The primary purpose was to determine if conventional therapy and PT or conventional therapy and mCIMT therapy show similar improvement in patients with chronic stroke. The secondary purpose was to investigate the effectiveness of conventional therapy and PT or mCIMT therapy in patients with chronic stroke and to compare which of the two interventions is more effective. METHODS: Forty patients with chronic stroke were randomly allocated to only conventional therapy (PTR, n = 14), conventional therapy plus proprioception training (PTR-PT, n = 13), and mCIMT (PTR-mCIMT, n = 13) groups. Evaluations were assessed before and 6 weeks after treatment. RESULTS: Intragroup evaluations revealeda significant improvement in the all scores in the PTR-PT and PTR-mCMIT groups (p = 0.006 < 0.001). Intergroup comparisons demonstrated that the PTR-mCIMT group had a significant improvement in spasticity and motor function scores compared to the PTR (p < 0.001) and the PTR-PT groups (p = 0.006–0.015). CONCLUSIONS: PT and mCMIT applied in addition to conventional therapy in patients with chronic stroke were more effective than only conventional therapy. Additionally, mCMIT showed greater improvement in spasticity and motor function scales than PT.

Revisiting dose and intensity of training: Opportunities to enhance recovery following stroke

PURPOSE

Stroke is a global leading cause of adult disability with survivors often enduring persistent impairments and loss of function. Both intensity and dosage of training appear to be important factors to help restore behavior. However, current practice fails to achieve sufficient intensity and dose of training to promote meaningful recovery. The purpose of this review is to propose therapeutic solutions that can help achieve a higher dose and/or intensity of therapy. Raising awareness of these intensive, high-dose, treatment strategies might encourage clinicians to re-evaluate current practice and optimize delivery of stroke rehabilitation for maximal recovery.

METHODS

Literature that tested and evaluated solutions to increase dose or intensity of training was reviewed. For each therapeutic strategy, we outline evidence of clinical benefit, supporting neurophysiological data (where available) and discuss feasibility of clinical implementation.

RESULTS

Possible therapeutic solutions included constraint induced movement therapy, robotics, circuit therapy, bursts of training, gaming technologies, goal-oriented instructions, and cardiovascular exercise.

CONCLUSION

Our view is that clinicians should evaluate current practice to determine how intensive high-dose training can be implemented to promote greater recovery after stroke.

Combining Action Observation Treatment with a Brain-Computer Interface System: Perspectives on Neurorehabilitation

Action observation treatment (AOT) exploits a neurophysiological mechanism, matching an observed action on the neural substrates where that action is motorically represented. This mechanism is also known as mirror mechanism. In a typical AOT session, one can distinguish an observation phase and an execution phase. During the observation phase, the patient observes a daily action and soon after, during the execution phase, he/she is asked to perform the observed action at the best of his/her ability. Indeed, the execution phase may sometimes be difficult for those patients where motor impairment is severe. Although, in the current practice, the physiotherapist does not intervene on the quality of the execution phase, here, we propose a stimulation system based on neurophysiological parameters. This perspective article focuses on the possibility to combine AOT with a brain–computer interface system (BCI) that stimulates upper limb muscles, thus facilitating the execution of actions during a rehabilitation session. Combining a rehabilitation tool that is well-grounded in neurophysiology with a stimulation system, such as the one proposed, may improve the efficacy of AOT in the treatment of severe neurological patients, including stroke patients, Parkinson’s disease patients, and children with cerebral palsy.

Modified Constraint-Induced Movement Therapy for persons with unilateral upper extremity amputation: A case report

STUDY DESIGN

Pretest/posttest case series design.

INTRODUCTION

Rates of prosthetic device abandonment are highest among persons with upper extremity (UE) amputation. Modified Constraint-Induced Movement Therapy (mCIMT), which has been extensively studied in patients with chronic, subacute, and acute stroke, is an under-utilized approach to treat persons with UE amputation.

PURPOSE OF THE STUDY

To present an mCIMT intervention for prosthetic device training after a unilateral UE amputation.

METHODS

The two cases from an advanced rehabilitation center herein described followed a standard UE amputation rehabilitation program used in conjunction with a home training program using mCIMT 3 hours a day, 5 days a week, for 3 weeks. Progress was evaluated weekly using the Activities Measure for Upper Limb Amputees (AM-ULA); Disabilities of the Arm, Shoulder, and Hand; Trinity Amputation and Prosthesis Experience Scales-Revised.

RESULTS

Both the cases exhibited an increase in observable and objective functional use with a UE prosthetic device, as indicated by the AM-ULA.

CONCLUSIONS

To our knowledge, this is the first description of mCIMT as part of a unilateral UE amputee rehabilitation program. The AM-ULA results show meaningful change, whereas Disabilities of the Arm, Shoulder, and Hand and Trinity Amputation and Prosthesis Experience Scales-Revised show mixed results.

Constraint-induced movement therapy protocols using the number of repetitions of task practice: a systematic review of feasibility and effects

BACKGROUND

High repetitions of task practice is required for the recovery of the motor function during constraint-induced movement therapy (CIMT). This can be achieved into ways: when the task practice is measured in hours of practice or when the number of repetitions is counted. However, it has been argued that using hours of task practice as a measure of practice does not provide a clear instruction on the dose of practice.

AIM

The aim of this study is to determine the feasibility and effects of the CIMT protocol that uses the number of repetitions of task practice.

MATERIALS/METHOD

The study was a systematic review registered in PROSPERO (CRD42020142140). Five databases, PubMED, CENTRAL, PEDro, OTSeeker and Web of Science, were searched. Studies of any designs in adults with stroke were included if they used the number of repetitions of task practice as a measure of dose. The methodological quality of the included studies was assessed using Modified McMaster critical review form. The results were analysed using qualitative synthesis.

RESULTS

Eight studies (n = 205) were included in the study. The number of task repetitions in the studies ranges between 45 and 1280 per day. The results showed that CIMT protocol using the number of repetitions of task practice was feasible and improved outcomes such as motor function, quality of life, functional mobility and spasticity.

CONCLUSION

The number of repetitions of task practice as a measure of CIMT dose can be used in place of the existing protocol that uses the number of hours of task practice.

Combined effects of Telehealth and Modified Constraint-Induced Movement Therapy for Individuals with Chronic Hemiparesis

Telehealth use allows improved access to services and results in potential cost savings. The purpose of this study was to examine the effectiveness of a combined modified Constrained Induced Movement Therapy (mCIMT) program using telehealth and in-person sessions, for participants with higher (Group 1) and lower (Group 2) functional ability of the hemiparetic upper extremity. Using a pre-experimental design with a 6-week intervention, 28 participants were assessed twice on use of upper extremity via subjective and objective measures. For the Motor Activity Log, the amount of use and quality of use were significant for Groups 1 and 2. Significant improvements were shown on the Wolf Motor Function Test (WMFT), the Fugl-Meyer UE, and the Functional Independence Measure (FIM) for both groups except for the strength subtest on the WMFT and the timed portion for Group 1. Percentages of attendance for telehealth and in-person sessions were also compared. Telehealth sessions had a higher attendance rate (84.5%) than in-person sessions (75.3%) (p=.004). The combined mCIMT program of telerehabilitation and in-person group sessions was effective in improving functional ability after a stroke.

Effectiveness of interventions to improve hand motor function in individuals with moderate to severe stroke: a systematic review protocol

INTRODUCTION

The human hand is extremely involved in our daily lives. However, the rehabilitation of hand function after stroke can be rather difficult due to the complexity of hand structure and function, as well as neural basis that supports hand function. Specifically, in individuals with moderate to severe impairment following a stroke, previous evidence for effective treatments that recover hand function in this population is limited, and thus has never been reviewed. With the progress of rehabilitation science and tool development, results from more and more clinical trials are now available, thereby justifying conducting a systematic review.

METHODS AND ANALYSIS

This systematic review protocol is consistent with the methodology recommended by the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols and the Cochrane handbook for systematic reviews of interventions. Electronic searches will be carried out in the PubMed, CINAHL, Physiotherapy Evidence Database and Cochrane Library databases, along with manual searches in the reference lists from included studies and published systematic reviews. The date range parameters used in searching all databases is between January 1999 and January 2019. Randomised controlled trials (RCTs) published in English, with the primary outcome focusing on hand motor function, will be included.

Effectiveness of a multifactorial context-enhancing functional therapy to promote functional arm use and recovery of stroke survivors: study protocol for a clinical trial

INTRODUCTION

After a stroke, 55% of survivors do not regain the ability to completely use their arm in daily life functioning. Currently, evidence-based guidelines recommend functional training for improving the affected hand after stroke. However, promoting an optimal quantity and quality of functional training is influenced by personal and environmental contextual factors. Studies that comprehensively target multiple factors regulating arm use are limited. This study compares the effects of functional training to multifactorial context-enhancing functional training program for improving functional arm use and recovery after stroke.

METHODS AND ANALYSIS

This is a protocol for an observer-blinded, two parallel groups, randomised controlled trial. A total of 126 community-dwelling subacute and chronic stroke survivors will be included in the study. A tailor-made multifactorial context-enhancing intervention-incorporating education, environmental enrichment and behaviour change techniques to reinforce functional training will be provided to the experimental group. The functional training group will be provided with functional exercises. The intervention will be delivered for 2 months. The primary outcomes of functional arm use and recovery will be measured using Motor Activity Log, Goal Attainment Scale and Rating of Everyday Arm-use in the Community and Home scale. The secondary outcomes of arm motor impairment and function will be measured using Fugl-Meyer upper limb score, Action Research Arm Test, ABILHAND questionnaire and Stroke Impact Scale. These will be measured at three points in time: before, after 2 months and after 1-month follow-up. The outcome measures will be analysed using one-way analysis of variance and regression analysis will be performed to identify factors limiting optimal task practice.

ETHICS AND DISSEMINATION

The study has been approved by the Institutional Ethics Committee of Kasturba Hospital, Manipal, India. Participants will sign a written informed consent prior to participation. The results will be published on completion of the trial and communicated to community-dwelling stroke survivors.

Is there a dose-dependent effect of modified constraint-induced movement therapy in patients with hemiplegia?

BACKGROUND

Impairment of upper extremity function is a common sequelae of stroke. It has been reported that modified constraint-induced movement therapy (mCIMT) could prove to be effective.

OBJECTIVE

To investigate the relationship between the intensity of rehabilitation such as treatment and constraining time, and the functional outcome for the paretic upper extremity in stroke patients through mCIMT.

METHODS

We conducted an observational prospective study of 31 patients with hemiplegia and subacute or chronic stroke. The mCIMT was performed for two weeks. Rehabilitation time and constraining time were variable among patients. The rehabilitation time included an individualized task-oriented program and conventional occupation treatment with an individualized therapist. The constraining time, with mit or splint, was also asked to self-record individually. The outcome was evaluated on the more affected side by the Wolf Motor Function Test, Fugl-Meyer Assessment, Motor Activity Log 14, and Functional Independence Measure for self-care tasks after the therapy.

RESULTS

All participants after the modified constraint-induced movement therapy program for two weeks improved on the evaluated outcome measures (P < 0.05). No significant correlation was found between the dose-dependent treatment or constraining time and outcomes. Comparisons improvement with subgroups based on the duration from onset, constraining component, dominant hand consistent with lesion side of stroke, and initial medical research council score for muscle strength, also showed no significant differences.

CONCLUSIONS

This is the first study on the effects of intensity of mCIMT with respect to time-dosage. Although all patients in this study showed improved functional status, no significant correlation between dose-dependent rehabilitation or constraining time and outcomes was seen.

Unilateral vs Bilateral Hybrid Approaches for Upper Limb Rehabilitation in Chronic Stroke: A Randomized Controlled Trial

OBJECTIVE

To investigate the effects of unilateral hybrid therapy (UHT) and bilateral hybrid therapy (BHT) compared with robot-assisted therapy (RT) alone in patients with chronic stroke.

DESIGN

A single-blind, randomized controlled trial.

SETTING

Four hospitals.

PARTICIPANTS

Outpatients with chronic stroke and mild to moderate motor impairment (N=44).

INTERVENTION

UHT combined unilateral RT (URT) and modified constraint-induced therapy. BHT combined bilateral RT (BRT) and bilateral arm training. The RT group received URT and BRT. The intervention frequency for the 3 groups was 90 min/d 3 d/wk for 6 weeks.

MAIN OUTCOME MEASURES

Fugl-Meyer Assessment (FMA, divided into the proximal and distal subscale) and Stroke Impact Scale (SIS) version 3.0 scores before, immediately after, and 3 months after treatment and Wolf Motor Function Test (WMFT) and Nottingham Extended Activities of Daily Living (NEADL) scale scores before and immediately after treatment.

RESULTS

The results favored BHT over UHT on the FMA total score and distal score at the posttest (P=.03 and .04) and follow-up (P=.01 and .047) assessment and BHT over RT on the follow-up FMA distal scores (P=.03). At the posttest assessment, the WMFT and SIS scores of the 3 groups improved significantly without between-group differences, and the RT group showed significantly greater improvement in the mobility domain of NEADL compared with the BHT group (P<.01).

CONCLUSIONS

BHT was more effective for improving upper extremity motor function, particularly distal motor function at follow-up, and individuals in the RT group demonstrated improved functional ambulation post intervention.

Subacute stroke physical rehabilitation evidence in activities of daily living outcomes: A systematic review of meta-analyses of randomized controlled trials

BACKGROUND

Stroke is a leading cause of disabilities worldwide. One of the key disciplines in stroke rehabilitation is physical therapy which is primarily aimed at restoring and maintaining activities of daily living (ADL). Several meta-analyses have found different interventions improving functional capacity and reducing disability.

OBJECTIVES

To systematically evaluate existing evidence, from published systematic reviews of meta-analyses, of subacute physical rehabilitation interventions in (ADLs) for stroke patients.

METHODS

Umbrella review on meta-analyses of RCTs ADLs in MEDLINE, Web of Science, Scopus, Cochrane, and Google Scholar up to April 2018. Two reviewers independently applied inclusion criteria to select potential systematic reviews of meta-analyses of randomized controlled trials (RCTs) of physical rehabilitation interventions (during subacute phase) reporting results in ADLs. Two reviewers independently extracted name of the 1st author, year of publication, physical intervention, outcome(s), total number of participants, and number of studies from each eligible meta-analysis. The number of subjects (intervention and control), ADL outcome, and effect sizes were extracted from each study.

RESULTS

Fifty-five meta-analyses on 21 subacute rehabilitation interventions presented in 30 different publications involving a total of 314 RCTs for 13,787 subjects were identified. Standardized mean differences (SMDs), 95% confidence intervals (fixed and random effects models), 95% prediction intervals, and statistical heterogeneity (I and Q test) were calculated. Virtual reality, constraint-induced movement, augmented exercises therapy, and transcranial direct current stimulation interventions resulted statistically significant (P < .05) with moderate improvements (0.5 ≤ SMD ≤ 0.8) and no heterogeneity (I = 0%). Moxibustion, Tai Chi, and acupuncture presented best improvements (SMD > 0.8) but with considerable heterogeneity (I2 > 75%). Only acupuncture reached "suggestive" level of evidence.

CONCLUSION

Despite the range of interventions available for stroke rehabilitation in subacute phase, there is lack of high-quality evidence in meta-analyses, highlighting the need of further research reporting ADL outcomes.

Constraint-induced movement therapy in a patient with ataxia after cerebellar tumor resection

Abstract Introduction: Constraint-induced movement therapy (CIMT) is a very modern method used in rehabilitation to treat individuals with functional impairment of the upper limbs. Objective: To apply the CIMT method and evaluate its effects in a patient with ataxia after removal of a cerebellar tumor. Method: This is a longitudinal interventional study of the case report type. The participant complained of tremors and difficulty writing and typing with the right hand as a result of the cerebellar tumor’s removal. She was subjected to CIMT daily in three-hour sessions for 10 days. The participant was evaluated with the Motor Activity Log (MAL) and the Wolf Motor Function Test (WMFT). Results: There was an improvement in the quantity, quality, speed, accuracy and strength with which the participant performed the tasks according to the MAL and WMFT scales. Improvement in writing was also identified and the report of better use of the member for daily tasks demonstrated the patient’s satisfaction after the end of therapy. Conclusion: This case report demonstrated the benefits of the application of the CIMT method in a patient with ataxia as a consequence of a rare cerebellar tumor, improving task execution time, strength and functional improvement of the affected upper limb.

Project Star Catcher

Modern immersive virtual reality experiences have the unique potential to motivate patients undergoing physical therapy for performing intensive repetitive task-based treatment and can be utilized to collect real-time user data to track adherence and compliance rates. This article reports the design and evaluation of an immersive virtual reality game using the HTC Vive for upper limb rehabilitation, titled “Project Star Catcher” (PSC), aimed at users with hemiparesis. The game mechanics were adapted from modified Constraint Induced Therapy (mCIT), an established therapy method where users are asked to use the weaker arm by physically binding the stronger arm. Our adaptation changes the physical to psychological binding by providing various types of immersive stimulation to influence the use of the weaker arm. PSC was evaluated by users with combined developmental and physical impairments as well as stroke survivors. The results suggest that we were successful in providing a motivating experience for performing mCIT as well as a cost-effective solution for real-time data capture during therapy. We conclude the article with a set of considerations for immersive virtual reality therapy game design.

Nonsurgical Treatment Options for Upper Limb Spasticity

Effects of 8-week sensory electrical stimulation combined with motor training on EEG-EMG coherence and motor function in individuals with stroke

The peripheral sensory system is critical to regulating motor plasticity and motor recovery. Peripheral electrical stimulation (ES) can generate constant and adequate sensory input to influence the excitability of the motor cortex. The aim of this proof of concept study was to assess whether ES prior to each hand function training session for eight weeks can better improve neuromuscular control and hand function in chronic stroke individuals and change electroencephalography-electromyography (EEG-EMG) coherence, as compared to the control (sham ES). We recruited twelve subjects and randomly assigned them into ES and control groups. Both groups received 20-minute hand function training twice a week, and the ES group received 40-minute ES on the median nerve of the affected side before each training session. The control group received sham ES. EEG, EMG and Fugl-Meyer Assessment (FMA) were collected at four different time points. The corticomuscular coherence (CMC) in the ES group at fourth weeks was significantly higher (p = 0.004) as compared to the control group. The notable increment of FMA at eight weeks and follow-up was found only in the ES group. The eight-week rehabilitation program that implemented peripheral ES sessions prior to function training has a potential to improve neuromuscular control and hand function in chronic stroke individuals.

Interventions to Improve Movement and Functional Outcomes in Adult Stroke Rehabilitation: Review and Evidence Summary

Background

Patients who have had a stroke may not be familiar with the terminology nor have the resources to efficiently search for evidence-based rehabilitation therapies to restore movement and functional outcomes. Recognizing that a thorough systematic review on this topic is beyond the scope of this article, we conducted a rapid review evidence summary to determine the level of evidence for common rehabilitation interventions to improve movement/motor and functional outcomes in adults who have had a stroke.

Objective

The objective of this study was to find evidence for common rehabilitation interventions to improve movement/motor and functional outcomes in adults who have had a stroke.

Methods

Medline Complete, PubMed, CINAHL Complete, Cochrane Database, Rehabilitation and Sports Medicine Source, Dissertation Abstracts International, and National Guideline Clearinghouse, from 1996 to April of 2016, were searched. From 348 articles, 173 met the following inclusion criteria: (1) published systematic reviews or meta-analyses, (2) outcomes target functional movement or motor skills of the upper and lower limbs, (3) non-pharmacological interventions that are commonly delivered to post-stroke population (acute and chronic), (4) human studies, and (5) English. Evidence tables were created to analyze the findings of systematic reviews and meta-analyses by category of interventions and outcomes.

Results

This rapid review found that the following interventions possess credible evidence to improve functional movement of persons with stroke: cardiorespiratory training, therapeutic exercise (ie, strengthening), task-oriented training (task-specific training), constraint-induced movement therapy (CIMT), mental practice, and mirror therapy. Neuromuscular electrical stimulation (NMES) (ie, functional electrical stimulation) shows promise as an intervention for stroke survivors.

Conclusions

Most commonly delivered therapeutic interventions to improve motor recovery after a stroke possess moderate quality evidence and are effective. Future research recommendations, such as optimal timing and dosage, would help rehabilitation professionals tailor interventions to achieve the best outcomes for stroke survivors.

Comparison of the effects of bilateral and unilateral training after stroke: A meta-analysis

BACKGROUND

The differential effects of bilateral and unilateral training on upper extremity (UE) function remain unclear.

OBJECTIVE

To compare the effectiveness of bilateral and unilateral training on UE function and activities of daily living (ADL) after stroke.

METHODS

Randomized controlled trials (RCTs) were selected for inclusion by two reviewers after searching the following databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and KoreaMed. Methodological qualities were assessed using the PEDro scale. Effect size was estimated by calculating the standardized mean difference (SMD).

RESULTS

Eleven RCTs of sufficient quality were included in our meta-analysis. The effect size on UE capacity was statistically significant in favor of the Constraint-Induced Movement Therapy (CIMT) groups (SMD [fixed], g: - 0.34; 95% CI: - 0.59-0.08; p = 0.01; I2 = 0%). No other SMDs were significant.

CONCLUSION

The CIMT tasks were more effective than bilateral training with regard to increased UE capacity; however, this result should be cautiously interpreted since the evaluation tools were designed for assessment of unilateral UE function, not bilateral UE function. Further, the effect of the CIMT tasks on UE capacity was not translated into ADL. Considering the disadvantages of CIMT such as fatigue, bilateral training may be more appropriate for improving ADL.

[The optimization of restoration approaches of advanced hand activity using the sensorial glove and the mCIMT method]

AIM

To reason the choice of methods of restoration of advanced hand activity depending on severity of motor disturbance in the top extremity.

MATERIAL AND METHODS

Eighty-eight patients were randomized into 3 groups: 1) the mCIMT group, 2) the 'touch glove' group, 3) the control group. For assessment of physical activity of the top extremity Fugl-Meyer Assessment Upper Extremity, Nine-Hole Peg Test, Motor Assessment Scale were used. Assessment of non-use phenomenon was carried out with the Motor Activity Log scale.

RESULTS AND CONCLUSION

At a stage of severe motor dysfunction, there was a restoration of proximal departments of a hand in all groups, neither method was superior to the other. In case of moderate severity of motor deficiency of the upper extremity the most effective was the method based on the principle of biological feedback - 'a touch glove'. In the group with mild severity of motor dysfunction, the best recovery was achieved in the mCIMT group.

The effects of mental practice combined with modified constraint-induced therapy on corticospinal excitability, movement quality, function, and activities of daily living in persons with stroke

PURPOSE

Studies on to what extent the combined therapy of modified constraint-induced movement therapy and mental practice is more effective than modified constraint-induced movement therapy alone are lacking. This study aims to compare the effects of the combined therapy with modified constraint-induced movement therapy alone on corticospinal excitability, quality of the movement of the affected upper extremity, upper motor functions, and performance of the affected arm in daily life of hemiplegic stroke patients.

METHODS

The participants comprised 14 people who had suffered stroke and were randomly divided into two groups. All participants participated in modified constraint-induced movement therapy, while only the experimental group partook in additional mental practice. Both groups were tested for corticospinal excitability, quality of movement, hand function, and activities of daily living.

RESULTS

Both groups showed significant improvement in the movement quality of reaching and performance of activities of daily living. In the experimental group, functional improvement of the upper limb was also observed. The improvements in corticospinal excitability, upper extremity function, and performance in daily activities were significantly greater in the experimental group compared to the control group.

CONCLUSIONS

This study confirmed that the combined therapy produces more effective improvement in corticospinal excitability, upper limb function, and performance in daily activities. The combined therapy of mental practice and modified constraint-induced movement therapy could be used as a clinically useful intervention. Implications for rehabilitation Modified constraint-induced movement therapy could be used as an intervention method for people with stroke to make improvements in the quality of movement and performance in activities of daily livings with the affected side. With additional mental practice, upper extremity functions improve, and changes in neurological, functional and performance in daily lives are greater compared to modified constraint-induced movement therapy without mental practice. Impact of mental practice has on rehabilitation should not be underestimated.

Video Game Rehabilitation for Outpatient Stroke (VIGoROUS): protocol for a multi-center comparative effectiveness trial of in-home gamified constraint-induced movement therapy for rehabilitation of chronic upper extremity hemiparesis

Background

Constraint-Induced Movement therapy (CI therapy) is shown to reduce disability, increase use of the more affected arm/hand, and promote brain plasticity for individuals with upper extremity hemiparesis post-stroke. Randomized controlled trials consistently demonstrate that CI therapy is superior to other rehabilitation paradigms, yet it is available to only a small minority of the estimated 1.2 million chronic stroke survivors with upper extremity disability. The current study aims to establish the comparative effectiveness of a novel, patient-centered approach to rehabilitation utilizing newly developed, inexpensive, and commercially available gaming technology to disseminate CI therapy to underserved individuals. Video game delivery of CI therapy will be compared against traditional clinic-based CI therapy and standard upper extremity rehabilitation. Additionally, individual factors that differentially influence response to one treatment versus another will be examined.

Methods

This protocol outlines a multi-site, randomized controlled trial with parallel group design. Two hundred twenty four adults with chronic hemiparesis post-stroke will be recruited at four sites. Participants are randomized to one of four study groups: (1) traditional clinic-based CI therapy, (2) therapist-as-consultant video game CI therapy, (3) therapist-as-consultant video game CI therapy with additional therapist contact via telerehabilitation/video consultation, and (4) standard upper extremity rehabilitation. After 6-month follow-up, individuals assigned to the standard upper extremity rehabilitation condition crossover to stand-alone video game CI therapy preceded by a therapist consultation. All interventions are delivered over a period of three weeks. Primary outcome measures include motor improvement as measured by the Wolf Motor Function Test (WMFT), quality of arm use for daily activities as measured by Motor Activity Log (MAL), and quality of life as measured by the Quality of Life in Neurological Disorders (NeuroQOL).

Discussion

This multi-site RCT is designed to determine comparative effectiveness of in-home technology-based delivery of CI therapy versus standard upper extremity rehabilitation and in-clinic CI therapy. The study design also enables evaluation of the effect of therapist contact time on treatment outcomes within a therapist-as-consultant model of gaming and technology-based rehabilitation.

Development of a tool to facilitate real life activity retraining in hand and arm therapy

Introduction

Successful recovery of upper extremity function after stroke is more likely when the affected limb is used regularly in daily life. We developed an iPad (Apple) application called the ‘Aid for Decision-Making in Occupation Choice for Hand’ to facilitate daily upper extremity use. This study examined the suitability of items and pictures in the Aid for Decision-Making in Occupation Choice for Hand, and tested a paper prototype of the application (which has since been produced).

Method

We used a Delphi method with 10 expert occupational therapists to refine the items in the aid. Next, we prepared pictures of items in the aid and confirmed their suitability by testing them with 10 patients (seven stroke, three cervical spondylotic myelopathy). Nine occupational therapists conducted field tests with a paper prototype of the aid in clinical practice to examine its utility.

Results

After four Delphi rounds, we selected 130 items representing activities of daily living, organized into 16 categories. Of 130 pictures, 128 were recognizable to patients as representing the intended activities. Based on testing of the paper prototype, we found the Aid for Decision-Making in Occupation Choice for Hand process was suitable for clinical practice, and could be organized into six steps.

Conclusion

The Aid for Decision-Making in Occupation Choice for Hand process may promote daily upper extremity use. This application, since developed, now needs to be clinically tested in its digital form.

Constraint-induced movement therapy as a rehabilitation intervention for upper extremity in stroke patients: systematic review and meta-analysis

Constraint-induced movement therapy (CIMT) is a neurorehabilitation technique designed to improve upper extremity motor functions after stroke. This review aimed to investigate evidence of the effect of CIMT on upper extremity in stroke patients and to identify optimal methods to apply CIMT. Four databases (MEDLINE, EMBASE, CINHAL, and PEDro) and reference lists of relevant articles and reviews were searched. Randomized clinical trials that studied the effect of CIMT on upper extremity outcomes in stroke patients compared with other rehabilitative techniques, usual care, or no intervention were included. Methodological quality was assessed using the PEDro score. The following data were extracted for each trial: patients' characteristics, sample size, eligibility criteria, protocols of CIMT and control groups, outcome measurements, and the PEDro score. A total of 38 trials were identified according to the inclusion criteria. The trials included were heterogeneous in CIMT protocols, time since stroke, and duration and frequency of treatment. The pooled meta-analysis of 36 trials found a heterogeneous significant effect of CIMT on upper extremity. There was no significant effect of CIMT at different durations of follow-up. The majority of included articles did not fulfill powered sample size and quality criteria. The effect of CIMT changed in terms of sample size and quality features of the articles included. These meta-analysis findings indicate that evidence for the superiority of CIMT in comparison with other rehabilitative interventions is weak. Information on the optimal dose of CIMT and optimal time to start CIMT is still limited.

Usability Evaluation of a VibroTactile Feedback System in Stroke Subjects

Background

To increase the functional capabilities of stroke subjects during activities of daily living, patients receive rehabilitative training to recover adequate motor control. With the goal to motivate self-training by use of the arm in daily life tasks, a sensor system (Arm Usage Coach, AUC) was developed that provides VibroTactile (VT) feedback if the patient does not move the affected arm above a certain threshold level. The objective of this study is to investigate the usability of this system in stroke subjects.

Method

The study was designed as a usability and user acceptance study of feedback modalities. Stroke subjects with mild to moderate arm impairments were enrolled. The subjects wore two AUC devices one on each wrist. VT feedback was given by the device on the affected arm. A semi-structured interview was performed before and after a measurement session with the AUC. In addition, the System Usability Scale (SUS) questionnaire was given.

Results

Ten ischemic chronic stroke patients (39 ± 38 months after stroke) were recruited. Four out of 10 subjects have worn the VT feedback on their dominant, affected arm. In the pre-measurement interview, eight participants indicated a preference for acoustic or visual over VT feedback. In the post evaluation interview, nine of 10 participants preferred VT over visual and acoustic feedback. On average, the AUC gave VT feedback six times during the measurement session. All participants, with the exception of one, used their dominant arm more then the non-dominant. For the SUS, eight participants responded above 80%, one between 70 and 80%, and one participant responded below 50%.

Discussion

More patients accepted and valued VT feedback after the test period, hence VT is a feasible feedback modality. The AUC can be used as a telerehabilitation device to train and maintain upper extremity use in daily life tasks.

Constraint-induced movement therapy in treatment of acute and sub-acute stroke: a meta-analysis of 16 randomized controlled trials

OBJECTIVE:

The aim of this meta-analysis was to evaluate the clinical efficacy of constraint-induced movement therapy in acute and sub-acute stroke.

DATA SOURCES:

The key words were stroke, cerebrovascular accident, constraint-induced therapy, forced use, and randomized controlled trial. The databases, including China National Knowledge Infrastructure, WanFang, Weipu Information Resources System, Chinese Biomedical Literature Database, PubMed, Medline, Embase, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews, were searched for studies on randomized controlled trials for treating acute or sub-acute stroke published before March 2016.

DATA SELECTION:

We retrieved relevant randomized controlled trials that compared constraint-induced movement therapy in treatment of acute or sub-acute stroke with traditional rehabilitation therapy (traditional occupational therapy). Patients were older than 18 years, had disease courses less than 6 months, and were evaluated with at least one upper extremity function scale. Study quality was evaluated, and data that met the criteria were extracted. Stata 11.0 software was used for the meta-analysis.

OUTCOME MEASURES:

Fugl-Meyer motor assessment of the arm, the action research-arm test, a motor activity log for amount of use and quality of movement, the Wolf motor function test, and a modified Barthel index.

RESULTS:

A total of 16 prospective randomized controlled trials (379 patients in the constraint-induced movement-therapy group and 359 in the control group) met inclusion criteria. Analysis showed significant mean differences in favor of constraint-induced movement therapy for the Fugl–Meyer motor assessment of the arm (weighted mean difference (WMD) = 10.822; 95% confidence intervals (95% CI): 7.419–14.226), the action research-arm test (WMD = 10.718; 95% CI: 5.704–15.733), the motor activity log for amount of use and quality of movement (WMD = 0.812; 95% CI: 0.331–1.293) and the modified Barthel index (WMD = 10.706; 95% CI: 4.417–16.966).

CONCLUSION:

Constraint-induced movement therapy may be more beneficial than traditional rehabilitation therapy for improving upper limb function after acute or sub-acute stroke.

Can Short-Term Constraint-Induced Movement Therapy Combined With Visual Biofeedback Training Improve Hemiplegic Upper Limb Function of Subacute Stroke Patients?

Objective

To Investigate the synergic effects of short-term constraint-induced movement therapy (CIMT) and visual biofeedback training (VBT) in subacute stroke patients.

Methods

Thirty-two subacute stroke patients were enrolled and randomly assigned to one of three groups: short-term CIMT with VBT, VBT only, and control groups. We applied CIMT for an hour daily during VBT instead of the ordinary restraint time, referred to as 'short-term' CIMT. Short-term CIMT with VBT group received simultaneous VBT with CIMT, whereas the VBT the only group received VBT without CIMT for an hour a day for 2 weeks. The control group received conventional occupational therapy (OT) alone. Patients underwent the Purdue Pegboard Test, the JAMAR grip strength test, the Wolf Motor Function Test, the Fugl-Meyer Assessment (upper extremity), Motricity index and the Korean version of Modified Barthel Index test to evaluate motor functions of the hemiplegic upper limb at baseline, post-treatment, and 2 weeks after treatment.

Results

No significant differences were observed between short-term CIMT with VBT and VBT only groups. Both groups showed significantly higher scores compared to the control group in the WMFT and FMA tests. However, the short-term CIMT with VBT group showed significant improvement (p<0.05) compared with the control group in both grasp and pad pinch at post-treatment and 2 weeks after treatment while the VBT only group did not.

Conclusion

Short-term CIMT with VBT group did not show significant improvement of hemiplegic upper limb function of subacute stroke patients, compared to VBT only group. Larger sample sizes and different restraint times would be needed to clarify the effect.

Efficacy of Modified Constraint Induced Movement Therapy in the Treatment of Hemiparetic Upper Limb in Stroke Patients: A Randomized Controlled Trial

INTRODUCTION

Paretic upper limb in stroke patients has a significant impact on the quality of life. Modified Constraint Induced Movement Therapy (mCIMT) is one of the treatment options used for the improvement of the function of the paretic limb.

AIM

To investigate the efficacy of four week duration mCIMT in the management of upper extremity weakness in hemiparetic patients due to stroke.

MATERIALS AND METHODS

Prospective single blind, parallel randomized controlled trial in which 30 patients received conventional rehabilitation programme (control group) and 30 patients participated in a mCIMT programme in addition to the conventional rehabilitation programme (study group). The mCIMT included three hours therapy sessions emphasizing the affected arm use in general functional tasks, three times a week for four weeks. Their normal arm was also constrained for five hours per day over five days per week. All the patients were assessed at baseline, one month and three months after completion of therapy using Fugl-Meyer Assessment (FMA) score for upper extremity and Motor Activity Log (MAL) scale comprising of Amount of Use (AOU) score and Quality of Use (QOU) score.

RESULTS

All the 3 scores improved significantly in both the groups at each follow-up. Post-hoc analysis revealed that compared to conventional rehabilitation group, mCIMT group showed significantly better scores at 1 month {FMA1 (p-value <0.0001, es0.2870), AOU1 (p-value 0.0007, es0.1830), QOU1 (p-value 0.0015, es0.1640)} and 3 months {FMA3 (p-value <.0001, es0.4240), AOU3 (p-value 0.0003, es 0.2030), QOU3 (p-value 0.0008, es 0.1790)}.

CONCLUSION

Four weeks duration for mCIMT is effective in improving the motor function in paretic upper limb of stroke patients.

Constraining movement reveals motor capability in chronic stroke: an initial study

OBJECTIVE

To determine if persons with chronic stroke and decreased hip and knee flexion during swing can walk with improved swing-phase kinematics when the task demands constrained gait to the sagittal plane.

DESIGN

A one-day, within-subject design comparing gait kinematics under two conditions: Unconstrained treadmill walking and a constrained condition in which the treadmill walking space is reduced to limit limb advancement to occur in the sagittal plane.

SETTING

Outpatient physical therapy clinic.

SUBJECTS

Eight individuals (mean age, 64.1 ±9.3, 2 F) with mild-moderate paresis were enrolled.

MAIN MEASURES

Spatiotemporal gait characteristics and swing-phase hip and knee range of motion during unconstrained and constrained treadmill walking were compared using paired t-test and Cohen's d ( d) to determine effect size.

RESULTS

There was a significant, moderate-to-large effect of the constraint on hip flexion ( p < 0.001, d = -1.1) during initial swing, and hip ( p < 0.05, d = -0.8) and knee ( p < 0.001, d = -1.1) flexion during midswing. There was a moderate effect of constraint on terminal swing knee flexion ( p = 0.238, d = -0.6). Immediate and significant changes in step width ( p < 0.05, d = 0.9) and paretic step length ( p < 0.05, d = -0.5) were noted in the constrained condition compared with unconstrained.

CONCLUSION

Constraining the treadmill walking path altered the gait patterns among the study's participants. The immediate change during constrained walking suggests that patients with chronic stroke may have underlying movement capability that they do not preferentially utilize.

Guidelines for Adult Stroke Rehabilitation and Recovery: A Guideline for Healthcare Professionals From the American Heart Association/American Stroke Association

PURPOSE

The aim of this guideline is to provide a synopsis of best clinical practices in the rehabilitative care of adults recovering from stroke.

METHODS

Writing group members were nominated by the committee chair on the basis of their previous work in relevant topic areas and were approved by the American Heart Association (AHA) Stroke Council's Scientific Statement Oversight Committee and the AHA's Manuscript Oversight Committee. The panel reviewed relevant articles on adults using computerized searches of the medical literature through 2014. The evidence is organized within the context of the AHA framework and is classified according to the joint AHA/American College of Cardiology and supplementary AHA methods of classifying the level of certainty and the class and level of evidence. The document underwent extensive AHA internal and external peer review, Stroke Council Leadership review, and Scientific Statements Oversight Committee review before consideration and approval by the AHA Science Advisory and Coordinating Committee.

RESULTS

Stroke rehabilitation requires a sustained and coordinated effort from a large team, including the patient and his or her goals, family and friends, other caregivers (eg, personal care attendants), physicians, nurses, physical and occupational therapists, speech-language pathologists, recreation therapists, psychologists, nutritionists, social workers, and others. Communication and coordination among these team members are paramount in maximizing the effectiveness and efficiency of rehabilitation and underlie this entire guideline. Without communication and coordination, isolated efforts to rehabilitate the stroke survivor are unlikely to achieve their full potential.

CONCLUSIONS

As systems of care evolve in response to healthcare reform efforts, postacute care and rehabilitation are often considered a costly area of care to be trimmed but without recognition of their clinical impact and ability to reduce the risk of downstream medical morbidity resulting from immobility, depression, loss of autonomy, and reduced functional independence. The provision of comprehensive rehabilitation programs with adequate resources, dose, and duration is an essential aspect of stroke care and should be a priority in these redesign efforts.

Effectiveness of interventions to improve occupational performance of people with motor impairments after stroke: an evidence-based review

We conducted a review to determine the effectiveness of interventions to improve occupational performance in people with motor impairments after stroke as part of the American Occupational Therapy Association's Evidence-Based Practice Project. One hundred forty-nine studies met inclusion criteria. Findings related to key outcomes from select interventions are presented. Results suggest that a variety of effective interventions are available to improve occupational performance after stroke. Evidence suggests that repetitive task practice, constraint-induced or modified constraint-induced movement therapy, strengthening and exercise, mental practice, virtual reality, mirror therapy, and action observation can improve upper-extremity function, balance and mobility, and/or activity and participation. Commonalities among several of the effective interventions include the use of goal-directed, individualized tasks that promote frequent repetitions of task-related or task-specific movements.

Constraint-induced movement therapy for upper extremities in people with stroke

BACKGROUND

In people who have had a stroke, upper limb paresis affects many activities of daily life. Reducing disability is therefore a major aim of rehabilitative interventions. Despite preserving or recovering movement ability after stroke, sometimes people do not fully realise this ability in their everyday activities. Constraint-induced movement therapy (CIMT) is an approach to stroke rehabilitation that involves the forced use and massed practice of the affected arm by restraining the unaffected arm. This has been proposed as a useful tool for recovering abilities in everyday activities.

OBJECTIVES

To assess the efficacy of CIMT, modified CIMT (mCIMT), or forced use (FU) for arm management in people with hemiparesis after stroke.

SEARCH METHODS

We searched the Cochrane Stroke Group trials register (last searched June 2015), the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library Issue 1, 2015), MEDLINE (1966 to January 2015), EMBASE (1980 to January 2015), CINAHL (1982 to January 2015), and the Physiotherapy Evidence Database (PEDro; January 2015).

SELECTION CRITERIA

Randomised control trials (RCTs) and quasi-RCTs comparing CIMT, mCIMT or FU with other rehabilitative techniques, or none.

DATA COLLECTION AND ANALYSIS

One author identified trials from the results of the electronic searches according to the inclusion and exclusion criteria, three review authors independently assessed methodological quality and risk of bias, and extracted data. The primary outcome was disability.

MAIN RESULTS

We included 42 studies involving 1453 participants. The trials included participants who had some residual motor power of the paretic arm, the potential for further motor recovery and with limited pain or spasticity, but tended to use the limb little, if at all. The majority of studies were underpowered (median number of included participants was 29) and we cannot rule out small-trial bias. Eleven trials (344 participants) assessed disability immediately after the intervention, indicating a non-significant standard mean difference (SMD) 0.24 (95% confidence interval (CI) -0.05 to 0.52) favouring CIMT compared with conventional treatment. For the most frequently reported outcome, arm motor function (28 studies involving 858 participants), the SMD was 0.34 (95% CI 0.12 to 0.55) showing a significant effect (P value 0.004) in favour of CIMT. Three studies involving 125 participants explored disability after a few months of follow-up and found no significant difference, SMD -0.20 (95% CI -0.57 to 0.16) in favour of conventional treatment.

AUTHORS' CONCLUSIONS

CIMT is a multi-faceted intervention where restriction of the less affected limb is accompanied by increased exercise tailored to the person's capacity. We found that CIMT was associated with limited improvements in motor impairment and motor function, but that these benefits did not convincingly reduce disability. This differs from the result of our previous meta-analysis where there was a suggestion that CIMT might be superior to traditional rehabilitation. Information about the long-term effects of CIMT is scarce. Further trials studying the relationship between participant characteristics and improved outcomes are required.

Effects of modified constraint-induced movement therapy combined with trunk restraint in chronic stroke: A double-blinded randomized controlled pilot trial

BACKGROUND

Reducing the compensatory mechanism by restraining the unnecessary movement may be helpful in relearning the upper-limb movement.

OBJECTIVE

To investigate the effects of a modified constraint-induced movement therapy (mCIMT) with trunk restraint (TR) in chronic stroke patients with moderate impairment.

METHODS

Eighteen participants with hemiparesis were randomly assigned to mCIMT + TR or mCIMT. Each group underwent 20 (1 h/d) intervention session (5 d/wk for 4 weeks). Patients were assessed with the action research arm test (ARAT), the Fugl-Meyer assessment upper extremity (FMA-UE), the modified Barthel index (MBI), and the motor activity log (MAL-AOU and MAL-QOM).

RESULTS

The mCIMT combined with trunk restraint group exhibited greater changes in the ARAT, FMA, MBI, and MAL (MAL-AOU and MAL-QOM) compared with the mCIMT group. Statistical analyses showed significantly different in ARAT (Z = -2.17, P = 0.03), FMA-UE (Z = -2.49, P = 0.01), MBI (Z = -2.44, P = 0.02), MAL-AOU (Z = -2.17, P = 0.03), and MAL-QOM (Z = -2.17, P = 0.03) between groups.

CONCLUSION

These finding suggest that mCIMT combined with trunk restraint is more helpful to improve upper-extremity function than mCIMT only in patient with chronic stroke.

Effect of Traditional Chinese Exercise on Gait and Balance for Stroke: A Systematic Review and Meta-Analysis

OBJECTIVE

A systematic review is conducted to determine the effect of traditional Chinese exercise for patients with stroke.

METHODS

Studies are obtained from PubMed, Embase, Cochrane Library, EBSCO, Web of Science, and CNKI. Only randomized controlled trials were left to evaluate the effects of traditional Chinese exercise for patients with stroke, and with no limits on study data or language. The primary outcome was the Berg balance score (BBS), Functional walking scale. And a random-effects model was used to calculate the pooled mean difference (MD) with 95% confidence interval (CI).

RESULTS

A total of 9 studies on 820 participants conform to the inclusion criteria, whereas eight studies on 704 participants are used as data sources for the meta-analysis, all trials were published between 2004 and 2013. The BBS indicates that the efficacy of traditional Chinese exercise on balance of patients with stroke is better than that of other training or no training in short term [MD (95%CI) = 11.85 [5.41, 18.30], P < 0.00001]. And the short physical performance battery, Functional walking scale, limit of stability were observed significant differences on balance (p<0.05) and gait (p<0.05) between traditional Chinese exercise and other exercises or no exercise. In addition, there is an article showed that some other form (physiotherapy exercises focused on balance) significantly improved balance ability for stroke patients compared to tai chi chuan practice (Berg test = 0.01, Romberg, and standing on one leg).

CONCLUSION

In our meta analysis, the positive findings of this study suggest traditional Chinese exercise has beneficial effects on the balance ability in short term. However, we drew the conclusion according to the extreme heterogeneity, and evidence of better quality and from a larger sample size is required. Because of the inconsistent outcomes, there are short of enough good evidence for patients with stroke to prove the effects of traditional Chinese exercise on gait.
