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

Effectiveness of modified constraint-induced movement therapy on upper limb function of stroke survivors in inpatient hospital settings: a systematic review and meta-analysis

PURPOSE

To synthesise evidence on the effectiveness of modified constraint-induced movement therapy on upper limb function in stroke survivors within inpatient hospital settings.

METHODS

A systematic review was pre-registered in PROSPERO (CRD42023421715b) and searched six databases (EMBASE, AMED, MEDLINE, CINAHL, Cochrane Library, OTseeker) up to November 2024.

Articles included adults with stroke undergoing modified constraint-induced movement therapy in inpatient hospital settings. Article quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. Homogenous data was synthesised in a meta-analysis and assessed using the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach. Remaining data was synthesised descriptively.

RESULTS

Ten randomised controlled trials (364 participants) were included. Four (191 participants) were analysed in a meta-analysis, showing modified constraint-induced movement therapy improved upper limb function (standardised mean difference (SMD) 0.94, 95% confidence interval (CI) 0.40 to 1.48), based on low-quality evidence. Five articles included follow-up, with two (90 participants) reporting sustained improvements. Five articles assessed activities of daily living, with two (136 participants) reporting positive effects.

CONCLUSION

Modified constraint-induced movement therapy improves upper limb function in the acute and sub-acute stages of stroke recovery within inpatient hospital settings. Sustainability of improvements and the impact on activities of daily living remains uncertain.

Progress in the application of motor imagery therapy in upper limb motor function rehabilitation of stroke patients with hemiplegia

Stroke is the leading cause of disability in Chinese adults. Upper limb motor dysfunction is a common manifestation of neurological dysfunction after stroke and can exert significant effects on a patient's daily living ability and quality-of-life. Therefore, it is crucial to provide appropriate rehabilitation treatment for upper limb motor function in stroke patients with hemiplegia. Currently, rehabilitation treatment for upper limb motor function in hemiplegic stroke patients in China includes motor therapy, neuro-promoting technology, occupational therapy, physical factor intervention, speech therapy, and swallowing therapy. Motor imagery therapy has also been shown to effectively promote the rehabilitation of upper limb function in stroke patients. Here, we review the concept, classification, mechanism of action, application, and effect of motor imagery therapy for the rehabilitation of upper limb motor function in stroke patients with hemiplegia in China. We summarize the available evidence, arising from Chinese experience, to support the implementation of this method in medical and rehabilitation institutions.

Transcutaneous electrical acupoint stimulation for upper limb motor recovery after stroke: a systematic review and meta-analysis

Background

Transcutaneous electrical acupoint stimulation (TEAS) is an innovative, non-invasive therapy that stimulates the contraction of paralyzed muscles in the upper limbs, promoting functional recovery. Several studies have demonstrated the efficacy of TEAS in restoring upper limb function. This study aims to evaluate the impact of TEAS on upper limb motor recovery after stroke.

Objectives

This study aims to evaluate the influence of TEAS on upper limb motor recovery after stroke and improve the quality of life in such patients.

Methods

Eight databases were systematically searched from inception to 1st October 2024. Two independent reviewers conducted the screening and data extraction of the study. The primary outcome measure was the Fugl Meyer Assessment of the Upper Extremity (FMA-UE), which evaluates upper extremity motor function in stroke patients. Secondary outcomes included the Modified Ashworth Scale (MAS) for assessing spasticity and the Modified Barthel Index (MBI) to evaluate patients' abilities to perform activities of daily living. Data synthesis was conducted using RevMan 5.4 and Stata 14.0. The GRADE method was employed to assess the quality of evidence.

Results

A total of 16 trials involving 1,218 stroke patients were included in this meta-analysis. Meta-analysis showed that the TEAS significantly improved upper limb function (SMD = 1.70, 95CI% = 1.09 to 2.31, p < 0.00001, I 2 = 93%; low certainty of evidence), reduced spasticity (SMD = -1.18, 95CI% = -1.79 to -0.58, p < 0.00001, I 2 = 90%; very low certainty of evidence), and enhanced the ability to perform daily activities (SMD = 1.53, 95CI% = 0.85 to 2.20, p < 0.00001, I 2 = 95%; low certainty of evidence).

Conclusion

Our results indicated that TEAS improved motor function and functional activities and reduced muscle tone in the upper limbs after stroke. However, these results should be interpreted with caution due to the limited strength of the evidence. High-quality, larger sample, multi-center studies are needed to validate these preliminary findings.

Research trends and hotspots of post-stroke upper limb dysfunction: a bibliometric and visualization analysis

Background

The global prevalence of stroke has been increasing. Motor dysfunction is observed in approximately 55 to 75% of stroke patients, with upper limb impairment affecting around 85% of them. Following upper limb dysfunction, the body's recovery time is not only slower compared to the lower limbs, but the restoration of its fine motor skills is significantly more challenging, greatly impacting the daily lives of patients. Consequently, there is an increasing urgency for study on the upper limb function in stroke.

Methods

A search was conducted in the Web of Science Core Collection: Science Citation Index Expanded (SCI-Expanded) database for material published from January 1, 2004 to December 31, 2023. We included all relevant literature reports and conducted an analysis of annual publications, countries/regions, institutions, journals, co-cited references, and keywords using the software packages CiteSpace, VOSviewer, and Bibliometrix R. Next, we succinctly outlined the research trends and hotspots in post-stroke upper limb dysfunction.

Results

This analysis comprised 1,938 articles from 1,897 institutions, 354 journals, and 53 countries or regions. A yearly rise in the production of publications was noted. The United States is the foremost nation on the issue. Northwestern University has the most amounts of papers compared to all other institutions. The journal Neurorehabilitation and Neural Repair is a highly significant publication in this field, with Catherine E. Lang serving as the principal author. The majority of the most-cited references focus on subjects such as the reliability and validity of assessment instruments, RCT of therapies, systematic reviews, and meta-analyses. The intervention measures primarily comprise three types of high-frequency phrases that are related, as determined by keyword analysis: intelligent rehabilitation, physical factor therapy, and occupational therapy. Current areas of focus in research include randomized clinical trials, neurorehabilitation, and robot-assisted therapy.

Conclusion

Current research has shown a growing interest in studying upper limb function assessment, occupational therapy, physical therapy, robot-assisted therapy, virtual reality, brain-computer interface, telerehabilitation, cortical reorganisation, and neural plasticity. These topics have become popular and are expected to be the focus of future research.

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.

Additional therapy promotes a continued pattern of improvement in upper-limb function and independence post-stroke

BACKGROUND

Upper-limb motor impairment after stroke is common and disabling. Growing evidence suggests that rehabilitation is effective in the chronic period. However, there is limited knowledge on the effects of ongoing targeted rehabilitation programs on patient outcomes.

OBJECTIVES

This study investigated the effects of delivering two programs of dose-matched evidence-based upper-limb rehabilitation to community-dwelling post-acute stroke patients with low, moderate and high motor-function.

MATERIALS AND METHODS

12 patients (2 female) aged 50.5±18.2 years and 13.8±10.8 months post-stroke completed 2-weeks of modified-Constraint-Induced Movement Therapy followed by 2-weeks of Wii-based Movement Therapy after a mean interval of 9.6±1.1 months (range 6-19months). Function was assessed at 6 time points (i.e. before and after each therapy program and 6-month follow-up after each program). Primary outcome measures were the Wolf Motor Function Test timed-tasks (WMFT-tt), upper-limb Fugl-Meyer Assessment (F-M) and the Motor Activity Log Quality of Movement Scale (MALQOM). Improvement and maintenance was analyzed using Paired T-Tests and Wilcoxon Signed Rank Tests.

RESULTS

Upper-limb function significantly improved on all primary outcome measures with the first therapy program (WMFT-tt p=0.008, F-M p=0.007 and MALQOM p<0.0001). All scores continued to improve with the second therapy program with significant improvements in the F-M (p=0.048) and the MALQOM (p=0.001).

CONCLUSIONS

All patients showed a pattern of continued improvement in upper-limb motor-function and independence in activities of daily living. These improvements demonstrate the benefit of ongoing post-stroke rehabilitation for community-dwelling stroke survivors for individuals of varying baseline functional status.

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.

Early transcranial direct current stimulation with modified constraint-induced movement therapy for motor and functional upper limb recovery in hospitalized patients with stroke: A randomized, multicentre, double-blind, clinical trial

BACKGROUND

Constraint-induced movement therapy (CIMT) and transcranial direct current stimulation (tDCS) are used to reduce interhemispheric imbalance after stroke, which is why the combination of these therapies has been used for neurological recovery, but not in the acute phase.

OBJECTIVES

To evaluate the effectiveness of combining active or sham bihemispheric tDCS with modified CIMT (mCIMT) for the recovery of the Upper Limb (UL) in hospitalized patients with acute and subacute stroke.

METHODS

This randomized controlled, double-blind, placebo-controlled, parallel group clinical trial was executed between September 2018 to March 2021 recruited 70 patients. The patients were randomized to one of two groups to receive treatment for 7 consecutive days, which included 20 min of active or sham bihemispheric tDCS daily (anodal ipsilesional and cathodal contralesional), with an mCIMT protocol. The primary outcome was the difference in the evolution of motor and functional upper limb recovery with assessment on days 0, 5, 7, 10 and 90. The secondary outcomes were independence in activities of daily living (ADL) and quality of life.

RESULTS

The active group presented a statistically significant gap compared to the simulated group throughout the trend in the scores of the FMA (motor function and joint pain) and WMFT (functional ability and weight to box) (p < 0.05) and showed a minimal clinically important difference (FMA: difference between groups of 4.9 points [CI: 0.007- 9.799]; WMFT: difference between groups of 6.54 points [CI: 1.10-14.15]). In the secondary outcomes, there was a significant difference between the groups in ADL independence (Functional Independence Measure: difference of 8.63 [CI: 1.37-18.64]) and perceived recovery of quality of life evaluated at 90 days (p = 0.0176).

CONCLUSIONS

Combining mCIMT with bihemispheric tDCS in patients hospitalized with acute-subacute stroke allows us to maximize the motor and functional recovery of the paretic upper limb in the early stages and independence in ADL, maintaining the effects over time.

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.

Brazilian practice guidelines for stroke rehabilitation: Part II

The Brazilian Practice Guidelines for Stroke Rehabilitation - Part II, developed by the Scientific Department of Neurological Rehabilitation of the Brazilian Academy of Neurology (Academia Brasileira de Neurologia, in Portuguese), focuses on specific rehabilitation techniques to aid recovery from impairment and disability after stroke. As in Part I, Part II is also based on recently available evidence from randomized controlled trials, systematic reviews, meta-analyses, and other guidelines. Part II covers disorders of communication, dysphagia, postural control and balance, ataxias, spasticity, upper limb rehabilitation, gait, cognition, unilateral spatial neglect, sensory impairments, home rehabilitation, medication adherence, palliative care, cerebrovascular events related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the future of stroke rehabilitation, and stroke websites to support patients and caregivers. Our goal is to provide health professionals with more recent knowledge and recommendations for better rehabilitation care after stroke.

The clinical effect of Kinesio taping and modified constraint-induced movement therapy on upper extremity function and spasticity in patients with stroke: a randomized controlled pilot study

BACKGROUND

Spasticity and impaired hand function are common complication in patients with stroke, and it pose negative impact on quality of life.

AIM

We aimed to assess the effect of the combined administration of kinesio taping (KT) and modified constraint-induced movement therapy (mCIMT) on upper extremity function and spasticity in hemiplegic patients with stroke.

DESIGN

A randomized controlled pilot study.

SETTING

A hospital center.

POPULATION

Patient of stroke with hemiplegia for 3-12 months.

METHODS

Thirty-five patients were enrolled and allocated into three groups, including the sham KT and mCIMT group, KT group, or KT and mCIMT group. The KT, sham KT, and mCIMT serve as additional therapies (5 days/week for 3 weeks) besides regular rehabilitation (5 days/week for 6 weeks). KT was applied over the dorsal side of the affected hand, while mCIMT was applied to restrain the unaffected upper extremity. The outcomes included the modified Tardieu scale (mTS), Brunnstrom stage, Box and Block Test (BBT), Fugl-Meyer assessment for the upper extremity (FMA-UE), and Stroke Impact Scale version 3.0. Measurements were taken at baseline, immediately after intervention (third week), and 3 weeks later (sixth week).

RESULTS

Between baseline and the third week, within-group comparisons yielded significant improvement in the wrist and hand parts of the FMA and BBT of the Sham KT and mCIMT group (P=0.007-0.035); in the hand part of the FMA, BBT, and mTS degree (P=0.005-0.024) of the KT group; and in the Brunnstrom stage of the wrist, FMA-UE, BBT, and mTS degrees (P=0.005-0.032) of the KT and mCIMT group. Between baseline and the sixth week, there was significant difference in the proximal part of the FMA and mTS degree in groups with KT, but an additional improvement on the Brunnstrom stage of the wrist was noted in the KT and mCIMT group.

CONCLUSIONS

KT benefits patients with stroke in spasticity reduction and upper extremity function. The combination of KT and mCIMT provides extra benefit in motor performance with a more long-lasting effect.

CLINICAL REHABILITATION IMPACT

Kinesio taping could act as potential adjuvant therapy in patient of stroke with hemiplegia.

Forced forelimb use following stroke enhances oligodendrogenesis and functional recovery in the rat

Forced limb use, which forces the use of the impaired arm following stroke, improves functional recovery. The study was designed to investigate the mechanisms of recovery underlying forced impaired limbuse. Furthermore, forced unimpaired arm use was also performed in order to explore its effect on functional behavior. We hypothesized that forced forelimb use could improve functional recovery in rats that have had an experimentally induced ischemic stroke, through promoting the recruitment and differentiation of the oligodendrocyte progenitor cells (OPCs). Indeed the proliferation of Olig2 and NG2 positive cells, as well as the expression of myelin basic protein (MBP)were increased in the perilesional striatum, whereas quantitative changes of Olig2+ and NG2+ oligodendrocyte progenitor cells was not observed in the subventricular zone. Through comparing rats forced to rely on affected or unaffected forelimb, the results demonstrated that forced impaired limb use boosted functional recovery. At the same time forced unimpaired limb use deteriorated limb movement of injured side. In addition, the expression of NogoA is reduced, when the injured limb was used more, suggesting that it played a role in the repair of white matter.

Early non-invasive brain stimulation with modified constraint-induced movement therapy for motor and functional upper limb recovery in stroke patients: Study protocol

Introduction

Upper limb motor impairment after a stroke is an important sequela. Constraint-induced movement therapy is a rehabilitation approach that has strong evidence. The incorporation of transcranial direct-current stimulation has been proposed; however, there is a lack of studies that confirm its benefits. The principal aim is to compare the effectiveness of 7 days of active versus sham bi-hemispheric transcranial direct-current stimulation, combined with modified constraint-induced movement therapy, for motor and functional recovery of the hemiparetic upper limb in subacute stroke patients.

Method/design

Randomized, double blind, sham-controlled, parallel group clinical trial in two stroke units. Participants: adults over 18 years, at least 2 days post unihemispheric stroke event, with hemiparesis, and without severe pain, aphasia or cognitive impairment. Intervention: Patients will receive 7 days of continuous therapy and be assigned to one of the treatment groups: active bi-hemispheric transcranial direct-current stimulation or sham bi-hemispheric transcranial direct-current stimulation. Measurement: Evaluations will take place at days 0, 5, 7 and 10, and at 3rd months. The Fugl-Meyer Assessment – Upper Extremity, Wolf Motor Function Test, Functional Independence Measure and Stroke Impact Scale are considered.

Discussion

Modified constraint-induced movement therapy plus transcranial direct-current stimulation in subacute stroke patients with hemiparesis could maximize motor and functional recovery. Trial registration: ClinicalTrials.gov identifier NCT03452254.

Predictors of Arm Nonuse in Chronic Stroke: A Preliminary Investigation

Background. Nonuse (NU) after stroke is characterized by failure to use the contralesional arm despite adequate capacity. It has been suggested that NU is a consequence of the greater effort and/or attention required to use the affected limb, but such accounts have not been directly tested, and we have poor understanding of the predictors of NU. Objective. We aimed to provide preliminary evidence regarding demographic, neuropsychological (ie, apraxia, attention/arousal, neglect), and psychological (ie, self-efficacy) factors that may influence NU in chronic stroke. Methods. Twenty chronic stroke survivors with mild to moderate sensory-motor impairment characterized by the Upper-Extremity Fugl-Meyer (UEFM) were assessed for NU with a modified version of the Actual Amount of Use Test (AAUT), which measures the disparity between amount of use in spontaneous versus forced conditions. Participants were also assessed with measures of limb apraxia, spatial neglect, attention/arousal, and self-efficacy. Using stepwise multiple regression, we determined which variables predicted AAUT NU scores. Results. Scores on the UEFM as well as attention/arousal predicted the degree of NU (P < .05). Attention/arousal predicted NU above and beyond UEFM (P < .05). Conclusions. The results are consistent with the importance of attention and engagement necessary to fully incorporate the paretic limb into daily activities. Larger-scale studies that include additional behavioral (eg, sensation, proprioception, spasticity, pain, mental health, motivation) and neuroanatomical measures (eg, lesion volume and white matter connectivity) will be important for future investigations.

Rehabilitation in acute stroke from the point of view of evidence-based medicine: possibilities of drug treatment

The review highlights the fundamental principles of early rehabilitation in ischemic stroke, the benefits and risks of early and very early patient mobilization. It presents data on the efficiency of CIMT-kinesiotherapy and mirror therapy in restoring upper extremity function, as well as procedures for nonpharmacological correction of spatial neglect syndrome. The effect on the rehabilitation of concomitant Alzheimer's disease is analyzed. The areas of pharmacological potentiation of poststroke rehabilitation, the efficiency of cerebrolysin in particular, are considered.

Strength training protocols in hemiparetic individuals post stroke: a systematic review

Abstract Introduction: Hemiparesis is one of the main sequels of stroke. Evidence suggests that muscle strength exercises are important in rehabilitation programs for hemiparetic patients, but wide variation in previously studied protocols makes the most suitable choice difficult in clinical practice. Objective: The aim of this study was to investigate strength training protocols for people with hemiparesis after stroke. Methods: A systematic review of literature was performed in the PubMed, PEDro (Physiotherapy Evidence Database), SciELO (Scientific Electronic Library Online), and LILACS (Latin American and Caribbean Literature in Health Science) databases. Only controlled clinical studies that contained strength training protocols for hemiparesis after stroke were selected. Results: In total, 562 articles were found. Of them, 12 were accepted for the systematic review. Although strength training protocols are effective in hemiparetic patients, we did not found a standard method for strength training. Conclusion: This systematic revision highlights the lack of a standard protocol for strength training, considering the following training parameters: volume, intensity, frequency, series, and repetitions. Isotonic exercises are most commonly used.
