Study to assess the effectiveness of modified constraint-induced movement therapy in stroke subjects: A randomized controlled trial

Background and Purpose:

The purpose of this study was to assess the effectiveness of modified constraint induced movement therapy (m-CIMT) in stroke subjects.

Materials and Methods:

A total of forty sub-acute stroke subjects were randomly assigned to either a m-CIMT (n = 20) or in a control group (n = 20). The m-CIMT group (14 men, 6 women; mean age = 55.2 years) consisted of structured 2 h therapy sessions emphasizing affected arm use, occurring 5 times/week for 2 weeks. A mitt was used to restrain the unaffected arm for 10 h/day for 2 week. The control group (11 men, 9 women; mean age = 56.4 years) consisted of conventional rehabilitation for time-matched exercise program. The outcome measures were evaluated at pre- and post-intervention by using the Wolf Motor Function Test (WMFT) and Fugl-Meyer assessment (FMA) of motor recovery after stroke.

Results:

After intervention significant effects were observed in m-CIMT group on WMFT (pre-test and post-test score was 28.04 ± 6.58, 13.59 ± 2.86; P =0.003). Similarly on FMA (pre- and post-test score was 31.15 ± 6.37, 55.7 ± 6.4; P = 0.00).

Conclusion:

There is a significant improvem ent in upper extremity function so it indicates that m-CIMT is effective in improving the motor function of the affected arm in stroke subjects. However, its long-term effect has not proved since there was no follow-up after intervention.     

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, Wan Fang, Weipu Information Resources System, Chinese Biomedical Literature Database, Pub Med, 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.     

Improvement of spontaneous language in stroke patients with chronic aphasia treated with music therapy: a randomized controlled trial

Aim of the study: The aim of this research is to evaluate the effects of active music therapy (MT) based on free-improvisation (relational approach) in addition to speech language therapy (SLT) compared with SLT alone (communicative-pragmatic approach: Promoting Aphasic's Communicative Effectiveness) in stroke patients with chronic aphasia. Materials and methods: The experimental group (n = 10) was randomized to 30 MT individual sessions over 15 weeks in addition to 30 SLT individual sessions while the control group (n = 10) was randomized to only 30 SLT sessions during the same period. Psychological and speech language assessment were made before (T0) and after (T1) the treatments. Results: The study shows a significant improvement in spontaneous speech in the experimental group (Aachener Aphasie subtest: p = 0.020; Cohen's d = 0.35); the 50% of the experimental group showed also an improvement in vitality scores of Short Form Health Survey (chi-square test = 4.114; p = 0.043). Conclusions: The current trial highlights the possibility that the combined use of MT and SLT can lead to a better result in the rehabilitation of patients with aphasia than SLT alone.     

Pilot randomized controlled trial to assess a physical therapy program on upper extremity function to counteract inactivity in chronic stroke

Background: In chronic stroke, feasible physical therapy (PT) programs are needed to promote function throughout life.

Objective: This randomized controlled pilot trial investigated the feasibility and effect of a PT program composed of strengthening exercises with elastic bands and bimanual functional training, with clearly defined doses based on the rate of perceived exertion (Borg scale), to counteract inactivity in chronic stroke.

Methods: Fifteen subjects > 6 month post-stroke were randomized to three-month of UE function training (UE group), or to lower extremity function training (LE group). At baseline (T0), post-intervention (T1) and three-month follow-up (T2) assessment included the Fugl-Meyer Assessment scale (FMA), Wolf Motor Function test (WMFT), grip strength, and muscle tone. Feasibility was also evaluated.

Results: The mixed-model ANOVAs revealed a significant interaction between the time and group factors for FMA (p < .001) and WMFT (p = .009). The UE group improved upper extremity function and motor recovery significantly more than the LE group. There was no significant interaction between treatment group and change in grip strength over time (p = .217). No between-group differences (p > .05) were found in muscle tone. In the UE group, the attendance rate was ≥85% for 71.4% of subjects and 85.7% showed high satisfaction. No adverse events were recorded. After treatment, adherence to the program was higher in the UE group.

Conclusions: The suggested PT program may be useful to improve the paretic UE function and motor recovery in chronic stroke. Moreover, it may be helpful to facilitate lifelong active involvement of stroke subjects in exercise.     

Sequential combination of robot-assisted therapy and constraint-induced therapy in stroke rehabilitation: a randomized controlled trial

Robot-assisted therapy (RT) and constraint-induced therapy (CIT) both show great promise to improve stroke rehabilitation outcomes. Although the respective treatment efficacy of RT and CIT has been validated, the additive effects of RT combined with CIT remain unknown. This study investigated the treatment effects of RT in sequential combination with a distributed form of CIT (RT + dCIT) compared with RT and conventional rehabilitation (CR). Forty-eight patients with stroke were enrolled and randomized to receive one of the three interventions for 4 weeks. Primary outcomes assessed the changes of motor impairment and motor function on the Fugl-Meyer Assessment (FMA) and Wolf Motor Function Test (WMFT). Secondary outcomes, including the Motor Activity Log (MAL) and accelerometers, examined functional performance during daily activities. The three treatment groups improved significantly on most primary and secondary outcomes over time. The combined RT + dCIT group exhibited significantly greater improvement on the FMA and functional ability subscale of the WMFT than the RT and CR groups. The improvements on the MAL and accelerometers were not significantly different among the three groups. RT in sequential combination with CIT led to additive effects on participants’ motor ability and functional ability to perform motor tasks after stroke, which support that combined therapy can be an effective means to intensify outcomes. Further research investigating the potential long-term effects of combination therapy, especially on real-life performance, would be valuable.     

A one-year follow-up after modified constraint-induced movement therapy for chronic stroke patients with paretic arm: a prospective case series study

Abstract

Background:

Despite the confirmed short-term effects of constraint-induced movement therapy, the long-term effects have not been sufficiently verified in terms of functional improvement of the affected arm.

Objective:

To evaluate the long-term effects and relationship between arm use in activities of daily living and arm improvement with modified constraint-induced movement therapy in chronic stroke patients.

Methods:

At 1 year after completing modified constraint-induced movement therapy, arm function (Fugl-Meyer Assessment) and amount of daily arm use (motor activity log) were assessed.

Results:

Fourteen post-stroke patients with mild to moderate impairment of arm function were analyzed. One year after completing modified constraint-induced movement therapy, participants consistently showed improvements in arm function and amount of daily arm use (analysis of variance: Fugl-Meyer Assessment, P?<?0.001; Motor Activity Log, P?<?0.001). For the Fugl-Meyer Assessment, post-hoc tests detected significant improvements (pre versus post, P?=?0.009; pre versus 1 year, P?<?0.0001; post versus 1 year, P?<?0.036). For the Motor Activity Log, post-hoc tests also detected significant improvements (pre versus post, P?=?0.0001; pre versus 1 year, P?<?0.0001; post versus 1 year, P?=?0.0014). The magnitude of the change in Fugl-Meyer Assessment score correlated significantly with the change in Motor Activity Log score (R?=?0.778, P?=?0.001).

Conclusions:

Among post-stroke patients with mild to moderate impairments of arm function, modified constraint-induced movement therapy without any other rehabilitation after intervention may improve arm function and increase arm use for 1 year. In addition, increasing arm use may represent an important factor in improving arm function, and vice versa.     

Improving balance with wobble board exercises in stroke patients: single-blind,randomized clinical trial

Background: A primary objective in stroke rehabilitation is to restore functional balance, in order to reduce falls.

Objectives: To identify the efficacy and safety of wobble board exercises when combined with conventional physiotherapy, in improving balance in hemiplegic patients following ischemic strokes.

Methods: A block-randomized, controlled, observer blinded, superiority trial was conducted on ambulatory hemiplegic patients following ischemic strokes of middle cerebral artery territory. Subjects in the control group received a conventional physiotherapy regime. Subjects in the intervention group received training on a wobble board combined with conventional physiotherapy. Main Outcome measures were the improvement of Four-Square Step Test (FSST) and the Berg Balance Scale (BBS), both of which assess functional balance at the end of 6 weeks.

Results: Thirty patients were randomly assigned for intervention (n = 15) and control (n = 15) groups. One patient dropped out from the study, leaving 29 eligible for the analysis. Intervention and control groups were comparable in sociodemographic characteristics and pre-test scores of balance. A repeated-measures MANOVA showed a significant difference in improvement of balance between the two study groups after 6 weeks [F(1,28) = 32.6,p = .000; Wilk’s lambda = .46]. The improvement of mean score of balance in interventional group was greater than in the control group [BBS:9.5 (intervention group),5.5 (control group); FSST:3.9 (intervention group),1.7 (control group)]. There were no injuries in both groups.

Conclusions: Wobble board exercises, when combined with the conventional physiotherapy, are safe and effective in restoring functional balance in patients with hemiplegia following ischemic strokes.     

Effects of group musical therapy on inpatients with chronic psychoses: a controlled study

The objective of the present study was to examine the efficacy of group musical therapy for inpatients with DSM-IV schizophrenia or schizoaffective psychosis. Thirty-four therapy group subjects in a ward for long-stay female patients received 15 group musical therapy sessions over 4 months, while 32 waiting group subjects from another ward with the same function were to wait for the sessions until the studied course was completed. The assessment included measures of psychotic symptoms, objective quality of life and subjective musical experiences. Comparison of the groups indicated that significant advantages in the therapy group subjects were detected in some measures concerning personal relations and a subjective sense of participation in a chorus activity. However, the follow-up evaluation suggested that the improvement might not be durable. These findings suggested that the musical therapy had some, but possibly only short-lived, effects on personal relations and musical experiences of chronic psychotic patients.     

The effect of a whole-body vibration therapy on the sitting balance of subacute stroke patients: a randomized controlled trial

Background: The use of a whole-body vibration (WBV) therapy has recently been applied and investigated as a rehabilitation method for subacute stroke patients.

Objective: To evaluate the effects of a WBV therapy on recovery of balance in subacute stroke patients who were unable to gain sitting balance.

Methods: The conventional rehabilitation group (CG) received conventional physical therapy, including sitting balance training by a physical therapist, for 30 min a one session, for twice a day for five days a week for two weeks. The whole-body vibration group (VG) received one session of conventional physical therapy, and received WBV therapy instead of conventional physical therapy for 30 min a day for five days a week for two weeks.

Results: There were 15 patients in the CG and 15 patients in the VG who completed the two-week therapy. After the two-week therapy, both groups showed functional improvement. Patients in the VG improved functional ambulation categories, Berg balance scale, trunk impairment scale scores. But, no statistically significant correlations between the therapeutic methods and outcomes were observed in either group.

Conclusion: Our results suggest that WBV therapy led to improvement of the recovery in balance recovery for subacute stroke patients. Because the WBV therapy was as effective as conventional physical therapy, we can consider a WBV therapy as a clinical method to improve the sitting balance of subacute stoke patients.     

Effects of trunk rehabilitation with kinesio and placebo taping on static and dynamic sitting postural control in individuals with chronic stroke: A randomized controlled trial

ABSTRACT

Background: Impaired trunk postural control is common after stroke. Combining kinesio taping with trunk rehabilitation has been shown to enhance the recovery of postural control ability in patients with stroke.

Objective: We investigated whether the combination of kinesio taping with trunk rehabilitation would improve dynamic and static sitting stability after stroke.

Methods: Twenty-eight patients with stroke were recruited and randomly assigned to one of the two 8-week trunk rehabilitation programs with kinesio (experimental group) or placebo taping (control group). Outcome measures were dynamic forward, dynamic backward, affected-side, and unaffected-side sway areas, static sway area and length, and the total limit of stability (LOS) area. The variables were measured using the BioRescue analysis system. All outcome measures were assessed at baseline and after 8 weeks of trunk rehabilitation.

Results: Significant increases were observed in the dynamic forward, dynamic backward, affected-side, and unaffected-side sway areas, and the total LOS area, in the experimental and control groups, whereas decreases were observed in the static sway area and length. The dynamic forward sway area was significantly higher in the experimental group than in the control group, but there were no significant differences between the groups in the other variables.

Conclusions: Trunk rehabilitation is effective for improving dynamic and static sitting stability after stroke. The addition of kinesio taping to the back muscles further increases forward mobility.     

Efficacy of constraint-induced therapy on functional performance and health-related quality of life for children with cerebral palsy: a randomized controlled trial

To better generalize training effects to the context of daily living, home-based constraint-induced therapy has been proposed. Therapeutic success of constraint-induced therapy is limited as to whether the improvements in functional performance can be transferred to quality of life. This randomized controlled trial aimed to investigate the efficacy of home-based constraint-induced therapy on functional performance and health-related quality of life. Twenty-two children with spastic unilateral cerebral palsy (6-8 years, 10 boys) were randomly assigned to receive constraint-induced therapy or traditional rehabilitation. Home-based constraint-induced therapy had immediate and maintaining effects on motor efficacy and functional performance and induced greater gains in health-related quality of life in the long run than in the short term. The home-based constraint-induced therapy protocol (relatively moderate intensity and shortened constraint time), which might balance the effectiveness and compliance of participants and caregivers, may be an effective alternative to conventional constraint-induced therapy.     

Mirror therapy and treadmill training for patients with chronic stroke: a pilot randomized controlled trial

Background: Previous lower-limb mirror therapy research has focused on non-weight bearing interventions.

Objectives: The primary aim of this study was to investigate the effect and feasibility of a combination of mirror therapy and treadmill training on post-stroke lower-limb recovery compared to a placebo intervention.

Methods: All patients (N = 30) walked on a treadmill for 30 min per day, 3 days per week, for 4 weeks. The mirror therapy and treadmill training group (n = 15) walked on the treadmill while viewing a reflection of their non-paretic limb in a mirror positioned in their mid-sagittal plane. The placebo group (n = 15) received no mirror visual feedback due to an altered mirror position. Primary outcome measures: Ten Metre Walk Test (10MWT) and Six Minute Walk Test (6MWT). Secondary outcome measures: Modified Ashworth Scale (MAS) and Fugl-Meyer Assessment-Lower Extremity (FMA-LE). Feasibility was appraised by examining participant compliance and any adverse events.

Results: No significant between group differences were demonstrated for the 10MWT, 6MWT or FMA-LE at post-training or 3-month follow-up assessment. A significant between group difference on the MAS was demonstrated in the reduction of ankle dorsiflexion muscle tone (p = 0.006) and ankle plantarflexion muscle tone (p = 0.01) in the mirror therapy group compared to the placebo group at post-training assessment but not at 3-month follow-up.

Conclusion: Our study reveals that in our group of patients with chronic stroke, mirror therapy combined with treadmill training facilitated significant reductions in ankle muscle tone (p < 0.05) compared to a placebo intervention.     

Effectiveness of therapeutic massage for generalized anxiety disorder: a randomized controlled trial

Background: Although massage is one of the most popular complementary and alternative medical (CAM) treatments for anxiety, its effectiveness has never been rigorously evaluated for a diagnosed anxiety disorder. This study evaluates the effectiveness of therapeutic massage for persons with generalized anxiety disorder (GAD). Methods: Sixty‐eight persons with GAD were randomized to therapeutic massage (n=23), thermotherapy (n=22), or relaxing room therapy (n=23) for a total of 10 sessions over 12 weeks. Mean reduction in anxiety was measured by the Hamilton Anxiety Rating Scale (HARS). Secondary outcomes included 50% reduction in HARS and symptom resolution of GAD, changes in depressive symptoms (Patient Health Questionnaire (PHQ‐8)), worry and GAD‐related disability. We compared changes in these outcomes in the massage and control groups posttreatment and at 6 months using generalized estimating equation (GEE) regression. Results: All groups had improved by the end of treatment (adjusted mean change scores for the HARS ranged from −10.0 to −13.0; P<.001) and maintained their gains at the 26‐week followup. No differences were seen between groups (P=.39). Symptom reduction and resolution of GAD, depressive symptoms, worry and disability showed similar patterns. Conclusions: Massage was not superior to the control treatments, and all showed some clinically important improvements, likely due to some beneficial but generalized relaxation response. Because the relaxing room treatment is substantially less expensive than the other treatments, a similar treatment packaged in a clinically credible manner might be the most cost effective option for persons with GAD who want to try relaxation‐oriented CAM therapies.

Effectiveness of mirror therapy on lower extremity motor recovery,balance and mobility in patients with acute stroke: A randomized sham-controlled pilot trial

Objective:

To evaluate the effectiveness of mirror therapy on lower extremity motor recovery, balance and mobility in patients with acute stroke.

Design:

A randomized, sham-controlled, assessor blinded, pilot trial.

Setting:

Inpatient stroke rehabilitation unit.

Subjects:

First time onset of stroke with mean post-stroke duration of 6.41 days, able to respond to verbal instructions, and Brunnstrom recovery stage 2 and above were enrolled.

Intervention:

Mirror therapy group performed 30 minutes of functional synergy movements of non-paretic lower extremity, whereas control group underwent sham therapy with similar duration. In addition, both groups were administered with conventional stroke rehabilitation regime. Altogether 90 minutes therapy session per day, six days a week, for two weeks duration was administered to both groups.

Outcome Measures:

Lower extremity motor subscale of Fugl Meyer Assessment (FMA), Brunnel Balance Assessment (BBA) and Functional Ambulation Categories (FAC).

Results:

Amongst the 22 patients included, equal number of patients participated in mirror group (N = 11) and control group (N = 11). Baseline variables were similar in both groups, except for Brunnstrom recovery stage. There was no statistical difference between groups, except for FAC. (FMA: P = 0.894; BBA: P = 0.358; FAC: P = 0.02). Significance was set at P < 0.05.

Conclusion:

Administration of mirror therapy early after stroke is not superior to conventional treatment in improving lower limb motor recovery and balance, except for improvement in mobility.Key Words: Acute stroke, balance, mobility, mirror therapy, motor recovery     

Four-week training involving ankle mobilization with movement versus static muscle stretching in patients with chronic stroke: a randomized controlled trial

Background: Patients with stroke generally have diminished balance and gait. Mobilization with movement (MWM) can be used with manual force applied by a therapist to enhance talus gliding movement. Furthermore, the weight-bearing position during the lunge may enhance the stretch force.

Objectives: This study aimed to compare the effects of a 4-week program of MWM training with those of static muscle stretching (SMS). Ankle dorsiflexion passive range of motion (DF-PROM), static balance ability (SBA), the Berg balance scale (BBS), and gait parameters (gait speed and cadence) were measured in patients with chronic stroke.

Methods: Twenty patients with chronic stroke participated in this study. Participants were randomized to either the MWM (n = 10) or the SMS (n = 10) group. Patients in both groups underwent standard rehabilitation therapy for 30 min per session. In addition, MWM and SMS techniques were performed three times per week for 4 weeks. Ankle DF-PROM, SBA, BBS score, and gait parameters were measured after 4 weeks of training.

Results: After 4 weeks of training, the MWM group showed significant improvement in all outcome measures compared with baseline (p < 0.05). Furthermore, SBA, BBS, and cadence showed greater improvement in the MWM group compared to the SMS group (p < 0.05).

Conclusions: This study demonstrated that MWM training, combined with standard rehabilitation, improved ankle DF-PROM, SBA, BBS scores, and gait speed and cadence. Thus, MWM may be an effective treatment for patients with chronic stroke.     

Motor learning curve and long-term effectiveness of modified constraint-induced movement therapy in children with unilateral cerebral palsy: A randomized controlled trial

The goal of this study was to determine the progression of manual dexterity during 6 weeks (54 h) (modified) constraint-induced movement therapy ((m)CIMT) followed by 2 weeks (18 h) bimanual training (BiT) in children with unilateral spastic cerebral palsy (CP), to establish whether and when a maximal training effect was reached and which factors might influence the motor learning curve. In addition, long-term retention of effects was determined. In a randomized controlled trial of 52 children with CP, aged 2.5–8 years, comparing mCIMT-BiT to conventional therapy, 28 children were allocated to the mCIMT-BiT group. This group was assessed weekly with the Box and Block test. Long-term effectiveness was determined by collecting follow-up data of the primary (Assisting Hand Assessment, ABILHAND-Kids) and secondary (Melbourne, COPM) outcomes at six months and one year after intervention. Fifteen children (53.6%) reached a maximum training effect within the mCIMT period. This group differed from others with respect to age, but not gender, affected side or manual ability. Children younger than five years had a greater chance to reach a maximum score within 6 weeks mCIMT (OR = 6.67, 95%CI = 1.24–35.71) that stabilized already after four weeks; older children showed a longer progression and tended to decline afterwards. In both age groups, beneficial effects were retained in the long term. The findings suggest that children of 5 years and older might profit from a longer period of mCIMT than 54 h to reach their maximum unimanual capacity and to retain this capacity during subsequent bimanual training.     

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

BackgroundConstraint-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.ObjectivesTo 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.MethodsThis 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.ResultsThe 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).ConclusionsCombining 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.
