Reliability, validity, and responsiveness of three scales for measuring balance in patients with chronic stroke

The effect of a motor relearning on balance and postural control in patients after stroke: An open-label randomized controlled trial

INTRODUCTION

Balance and postural control impairments are common in stroke patients, increasing fall risk and limiting their daily and social activities. Current research lacks comprehensive studies evaluating the efficacy and long-term effects of task-specific training on balance and postural control among stroke patients, especially when considering biomechanical and posturographic assessments.

PATIENTS AND METHODS

A randomized controlled trial included 63 subacute stroke patients recruited from the outpatient rehabilitation department. Participants were randomly assigned to the MRP group (n=32), receiving task-specific training based on MRP, or the CPT group (n=31), receiving conventional physical therapy. Both groups completed an 8-week intervention (3 sessions/week; 1 h./session). Balance and postural control were assessed at baseline, post-intervention, and 3-month follow-up using the Berg Balance Scale (BBS) and posturography.

RESULTS

The MRP group exhibited significantly larger improvements than the CPT group in both BBS scores (p=0.001, d=2.98, 95% CI [2.25, 3.70]) and Balance Index scores (p=0.001, d=2.83, 95% CI [2.12, 3.53]) after the intervention. These improvements were sustained at 3-month follow-up.

DISCUSSION

The findings suggest that task-specific training based on MRP is more effective than CPT for improving balance and postural control. The MRP intervention may enhance the motor learning and neural plasticity of the patients, leading to better functional outcomes. However, the study's open-label design represents a limitation, and further research with adequate blinding is needed.

CONCLUSION

Task-specific training based on MRP was superior to CPT for improving balance and postural control in subacute stroke patients. Participants undergoing MRP exhibited significant and clinically relevant improvements that were sustained at follow-up.

Parallel-Forms Reliability and Minimal Detectable Change of the Four Telerehabilitation Version Mobility-Related Function Scales in Stroke Survivors

OBJECTIVE

To investigate the parallel-forms reliability, minimal detectable change with 95% confidence interval (MDC95), and feasibility of the 4 telerehabilitation version mobility-related function scales: Fugl-Meyer Assessment-lower extremity subscale (Tele-FMA-LE), Berg Balance Scale (Tele-BBS), Tinetti Performance Oriented Mobility Assessment-Gait subscale (Tele-POMA-G), and Rivermead Mobility Index (Tele-RMI).

DESIGN

Reliability and agreement study and cross-sectional study.

SETTING

Medical center.

PARTICIPANTS

Stroke survivors' ability to independently walk 3 meters with assistive devices, age of ≥18 years for participants and their partners, stable physical condition, and absence of cognitive impairment (N=60).

INTERVENTIONS

Not applicable.

MAIN OUTCOMES MEASURES

Parallel-forms reliability and MDC95 of Tele-FMA-LE, Tele-BBS, Tele-POMA-G, and Tele-RMI.

RESULTS

No significant differences (P>.05) were observed among the mean scores of the telerehabilitation version and face-to-face version mobility-related function scales. Intraclass correlation coefficients (ICCs) indicated good reliability for most scales, with Tele-FMA-LE, Tele-BBS, and Tele-RMI scores achieving values of 0.81, 0.78, and 0.84. Tele-POMA-G scores demonstrated moderate reliability (ICC=0.72). Weighted kappa (κw) showed good-to-excellent reliability for most individual items (κw>0.60). The MDCs of the Tele-FMA-LE, Tele-BBS, Tele-POMA-G, and Tele-RMI were 5.84, 8.10, 2.74, and 1.31, respectively. Bland-Altman analysis showed adequate agreement between tele-assessment and face-to-face assessment for all scales. The 5 dimensions affirm the robust feasibility of tele-assessment: assessment time, subjective fatigue perception, overall preference, participant satisfaction, and system usability.

CONCLUSIONS

The study demonstrates good parallel-forms reliability, MDC, and promising feasibility of the 4 telerehabilitation version mobility-related function scales (Tele-FMA-LE, Tele-BBS, Tele-POMA-G, and Tele-RMI) in survivors of stroke.

Effects of Rehabilitation Robot Training on Physical Function, Functional Recovery, and Daily Living Activities in Patients with Sub-Acute Stroke

Stroke often results in sensory deficits, muscular weakness, and diminished postural control, thereby restricting mobility and functional capabilities. It is important to promote neuroplasticity by implementing task-oriented exercises that induce changes in patients. Therefore, this study aimed to investigate the effects of rehabilitation robot training on physical function, functional recovery, and activities of daily living (ADLs) in patients with subacute stroke. The study participants were patients with subacute stroke receiving treatment at Hospitals A and B. They were selected as research subjects based on selection and exclusion criteria. The experimental group received rehabilitation robot training in sessions of 30 min, five times weekly, for a total of 20 sessions over four weeks. Conversely, the control group underwent standard rehabilitation equipment training with an identical frequency, duration, and number of sessions. Measurements were taken before and after the training period to assess changes in physical function, functional recovery, and activities of daily living using tools such as the MMT, BBS, FBG, FAC, FIM, and MBI. The results were as follows: in the within-group comparison, the rehabilitation robot training group showed significant differences in MMT, BBS, FBG, FAC, FIM, and MBI (p < 0.05), while the control group showed significant differences in FIM (p < 0.05). Statistically significant differences were observed in the time, group, and time × group interaction effects among the MMT, static seated FBG, dynamic seated FBG, FIM, and MBI (p < 0.05). Based on these results, rehabilitation robotic training resulted in significant improvements in physical function, functional recovery, and activities of daily living in patients with subacute stroke. Based on these findings, providing a basic protocol for a rehabilitation program that applies rehabilitation robot training to patients with subacute stroke may offer more effective treatment and outcomes in the future.

Reliability and Validity of the Spanish Version of the Brief-BESTest in Stroke Patients

Background: Balance disorders and postural control treatments play an important role in fall prevention. The Brief-BESTest is a short-scale employed to evaluate balance and fall risk in different populations. Balance assessment is a fundamental element in patients with Acquired Brain Injury rehabilitation since postural alteration is one of the most frequent sequelae. The objective was to validate the Spanish version of the Brief-BESTest questionnaire in the stroke population. Methods: Subjects of both sexes aged over 18 years with a diagnosis of acute/chronic stroke were included. The BESTest, Mini-BESTest, Brief-BESTest, Berg Balance Scale, and Timed Up & Go Test were used to assess balance. The scales were implemented once. Cronbach's alpha coefficient was used to assess the internal consistency and confirmatory factorial analysis was employed to assess validity. Results: A total of 44 patients with a mean age of 65.35 years (SD = 10.665) participated. Cronbach's alpha coefficient showed a high internal consistency with a value of 0.839. In the criterion validity, there was a high positive correlation between the Brief-BESTest and BESTest (r = 0.879), Mini-BESTest (r = 0.808), and Berg Balance Scale (r = 0.711). Conclusion: The Spanish version of the Brief-BESTest scale is valid and reliable, showing adequate psychometric properties for balance assessment in patients with acute or chronic stroke.

Effect of adding systematic desensitization to goal-directed paradigm on risk of falling in patients with stroke: a randomized controlled trial

Background

Improvement in rehabilitation outcomes for patients suffering from chronic stroke can be attained through systematic desensitization of their fear of falling, which in turn reduces the risk of falling.

Purpose

This study aimed to examine the effect of adding systematic desensitization to a goal-directed paradigm on functional performance, balance, risk of falling, and fear of falling among chronic ischemic stroke patients.

Methodology

Two equally sized groups, each comprising 40 stroke patients of both sexes, were randomly divided. For 8 weeks, Group A received three sessions per week of combined treatment consisting of systematic desensitization and a goal-directed paradigm, while Group B received only the goal-directed paradigm. The Timed Up and Go (TUG) test and Dynamic Gait Index (DGI) were used to assess function performance; the Berg Balance Scale (BBS) and the Biodex Fall Risk Index (FRI) were used to evaluate balance; and the 16-item Fall Efficacy Scale-International (FES-I) was used to evaluate fear of falling. At baseline and after the treatment, all measurements were obtained.

Results

Both groups (A and B) revealed a substantial increase in functional performance through a decrease in TUG scores and an increase in DGI. Additionally, there was a decrease in the risk of falling through an increase in the BBS scores and a decrease in the FRI. Furthermore, there was a decrease in the fear of falling, as measured using the FES-I, after treatment, with superior improvement in Group A with a p-value of <0.001.

Conclusion

Systematic desensitization combined with a goal-directed paradigm has a superior effect on improving functional performance and reducing the risk of falling and the fear of falling in patients with stroke compared to a goal-directed paradigm alone.

Validity of an android device for assessing mobility in people with chronic stroke and hemiparesis: a cross-sectional study

BACKGROUND

Incorporating instrument measurements into clinical assessments can improve the accuracy of results when assessing mobility related to activities of daily living. This can assist clinicians in making evidence-based decisions. In this context, kinematic measures are considered essential for the assessment of sensorimotor recovery after stroke. The aim of this study was to assess the validity of using an Android device to evaluate kinematic data during the performance of a standardized mobility test in people with chronic stroke and hemiparesis.

METHODS

This is a cross-sectional study including 36 individuals with chronic stroke and hemiparesis and 33 age-matched healthy subjects. A simple smartphone attached to the lumbar spine with an elastic band was used to measure participants' kinematics during a standardized mobility test by using the inertial sensor embedded in it. This test includes postural control, walking, turning and sitting down, and standing up. Differences between stroke and non-stroke participants in the kinematic parameters obtained after data sensor processing were studied, as well as in the total execution and reaction times. Also, the relationship between the kinematic parameters and the community ambulation ability, degree of disability and functional mobility of individuals with stroke was studied.

RESULTS

Compared to controls, participants with chronic stroke showed a larger medial-lateral displacement (p = 0.022) in bipedal stance, a higher medial-lateral range (p < 0.001) and a lower cranio-caudal range (p = 0.024) when walking, and lower turn-to-sit power (p = 0.001), turn-to-sit jerk (p = 0.026) and sit-to-stand jerk (p = 0.001) when assessing turn-to-sit-to-stand. Medial-lateral range and total execution time significantly correlated with all the clinical tests (p < 0.005), and resulted significantly different between independent and limited community ambulation patients (p = 0.042 and p = 0.006, respectively) as well as stroke participants with significant disability or slight/moderate disability (p = 0.024 and p = 0.041, respectively).

CONCLUSION

This study reports a valid, single, quick and easy-to-use test for assessing kinematic parameters in chronic stroke survivors by using a standardized mobility test with a smartphone. This measurement could provide valid clinical information on reaction time and kinematic parameters of postural control and gait, which can help in planning better intervention approaches.

Absolute and relative intrarater reliability of the modified motor assessment scale according to Uppsala academic hospital -99

BACKGROUND

For some of the most commonly used motor measures, psychometric properties, and minimal detectable change (MDC95) remain largely unknown, limiting the interpretability of tests.

OBJECTIVE

The aim was to establish intrarater reliability, MDC95 and floor- and ceiling effects for a modified version of the Motor Assessment Scale (M-MAS UAS-99).

METHODS

Data was derived from an intervention study that enrolled 41 individuals with chronic stroke. Test scores from two subsequent assessments with 3 weeks apart were used for establishing the floor and ceiling effect, the intraclass correlation coefficient (ICC[2,1]), standard error mean (SEM) and the MDC95 for the total score, and subdomains of the M-MAS UAS-99.

RESULTS

The intrarater reliability was excellent with an ICC[2,1] between 0.970 and 0.995 for both total score and subdomains. The MDC95 for the M-MAS UAS-99 total score was 1.22 which means ≥ 2.0 points on an individual basis. For bed mobility subdomain, a ceiling effect was seen, but not for the total score of the test. No floor effect was seen for the test.

CONCLUSION

M-MAS UAS-99 has excellent intrarater reliability. Any individual increase in test scores must reach 2.0 to be considered a true change.

Clinical prediction rules for multi surfaces walking independence using the Berg Balance Scale or Mini-Balance Evaluation Systems Test in persons with stroke

BACKGROUND

A Clinical prediction rule (CPR) for determining multi surfaces walking independence in persons with stroke has not been established.

OBJECTIVES

To develop a CPR for determining multi surfaces walking independence in persons with stroke.

METHODS

This was a multicenter retrospective analysis of 419 persons with stroke. We developed a Berg Balance Scale (BBS)-model CPR combining the BBS, comfortable walking speed (CWS) and cognitive impairment, and a Mini-Balance Evaluation Systems Test (Mini-BESTest)-model CPR combining the Mini-BESTest, CWS, and cognitive impairment. A logistic regression analysis was conducted with multi surfaces walking independence as the dependent variable and each factor as an independent variable. The identified factors were scored (0, 1) based on reported cutoff values. The CPR's accuracy was verified by the area under the curve (AUC). We used a bootstrap method internal validation and calculated the CPR's posttest probability.

RESULTS

The logistic regression analysis showed that the BBS, CWS, and cognitive impairment were factors in the BBS model, and the Mini-BESTest was a factor in the Mini-BESTest model. The CPRs were 0-3 points for the BBS model and 0-1 points for the Mini-BESTest model. The AUCs (bootstrap mean AUC) of the CPR score were 0.89 (0.90) for the BBS model and 0.72 (0.72) for the Mini-BESTest model. The negative predictive value (negative likelihood ratio) was 97% (0.054) for CPR scores < 2 for the BBS model and 94% (0.060) for CPR scores < 1 for the Mini-BESTest model.

CONCLUSIONS

The CPR developed herein is useful for determining multi surfaces walking independence.

Robotic gait training and botulinum toxin injection improve gait in the chronic post-stroke phase: A randomized controlled trial

BACKGROUND

Improving walking ability is one of the main goals of rehabilitation after stroke. When lower limb spasticity increases walking difficulty, botulinum toxin type A (BTx-A) injections can be combined with non-pharmacologic interventions such as intensive rehabilitation using a robotic approach. To the best of our knowledge, no comparisons have been made between the efficacy of robotic gait training and conventional physical therapy in combination with BTx-A injections.

OBJECTIVE

To conduct a randomized controlled trial to compare the efficacy on gait of robotic gait training versus conventional physiotherapy after BTx-A injection into the spastic triceps surae in people after stroke.

METHOD

Thirty-three participants in the chronic stroke phase with triceps surae spasticity inducing gait impairment were included. After BTx-A injection, participants were randomized into 2 groups. Group A underwent robotic gait training (Lokomat®) for 2 weeks, followed by conventional physiotherapy for 2 weeks (n = 15) and Group B underwent the same treatment in reverse order (n = 18). The efficacy of these methods was tested using the 6-minute walk test (6MWT), comparing post-test 1 and post-test 2 with the pre-test.

RESULTS

After the first period, the 6MWT increased significantly more in Group A than in Group B: the mean difference between the interventions was 33 m (95%CI 9; 58 p = 0.007; g = 0.95), in favor of Group A; after the second period, the 6MWT increased in both groups, but the 30 m difference between the groups still remained (95%CI 5; 55 p = 0.019; g = 0.73).

CONCLUSION

Two weeks of robotic gait training performed 2 weeks after BTx-A injections improved walking performance more than conventional physiotherapy. Large-scale studies are now required on the timing of robotic rehabilitation after BTx-A injection.

Validity and intra- and inter-rater reliability of the Tinetti performance-oriented mobility assessment balance subscale using different tele-assessment methods in patients with chronic stroke

INTRODUCTION

Balance assessments are an important component of rehabilitation. Considering the increasing use of telemedicine to meet rehabilitation needs, it is important to examine the feasibility of such assessments. This study aimed to examine the reliability and validity of the Tinetti Performance-Oriented Mobility Assessment Balance Subscale (POMA-B) when applied via synchronous and asynchronous tele-assessment.

METHODS

Twenty-five patients with chronic stroke were included in the study. The first physiotherapist assessed the patients on the first day in a face-to-face clinical setting. Synchronous or asynchronous tele-assessment was applied the next day. The assessments were performed in the same time zone, with an interval of one day. The synchronous tele-assessment was done online in real time by the first and second physiotherapists. A reference assessment video was sent to the patients for asynchronous tele-assessment. They were asked to make a video recording while performing the evaluation activities according to the reference video. Then the first and second physiotherapists assessed these video recordings separately. All the tests were repeated 10 days later to determine the intra-rater reliability of the tele-assessment methods.

RESULTS

The intra-class correlation coefficients ranged from 0.96 to 0.98 for inter-rater reliability and from 0.97 to 0.98 for intra-rater reliability for both tele-assessment methods. Both asynchronous and asynchronous tele-assessment methods were medium correlated with the face-to-face versions.

CONCLUSIONS

We demonstrated the validity and reliability of the POMA-B in chronic stroke patients with different tele-assessment methods, typically using the internet and available devices.

Comparison of usefulness between the Mini-Balance Evaluation Systems Test and the Berg Balance Scale for measuring balance in patients with subacute stroke: a prospective cohort study

Introduction

The aim of this study was to compare the clinical applicability of the Mini-Balance Evaluation Systems Test and the Berg Balance Scale for measuring balance in inpatients with subacute stroke.

Methods

This was a prospective observational study which included 58 consecutive patients admitted to a convalescent rehabilitation hospital with a first-ever stroke and who met the inclusion/exclusion criteria. The Mini-Balance Evaluation Systems Test and the Berg Balance Scale were used to assess patient balance at admission and discharge. The ceiling and floor effects and responsiveness of each balance score were examined. In addition, receiver operating characteristic analysis based on each balance score at admission was used to examine its discriminative power to predict ambulatory independence and falls during hospitalization.

Results

The mean (standard deviation) change between admission and discharge for each balance scale was 4.4 (4.7) for the Mini-Balance Evaluation Systems Test and 8.3 (10.0) for the Berg Balance Scale, with standard response means, a measure of responsiveness of 0.9 (large) and 0.8 (medium), respectively. Each balance score at admission almost equally predicted gait independence and fallers during hospitalization. On the contrary, only the distribution of scores on the Berg Balance Scale at discharge showed a ceiling effect, with 25 patients (43%) obtaining a perfect score.

Discussion

The Mini-Balance Evaluation Systems Test may be useful as a balance measure for inpatients with subacute stroke because it is less susceptible to ceiling effects and more responsive than the Berg Balance Scale.

Comparison of a single session of tDCS on cerebellum vs. motor cortex in stroke patients: a randomized sham-controlled trial

OBJECTIVE

The purpose of this study was to determine whether a single session of trans-cranial direct current stimulation (tDCS) of the cerebellum and M1 has any advantages over one another or sham stimulation in terms of balance, gait and lower limb function.

METHODS

A total of 66 patients who had experienced their first ever stroke were recruited into three groups for this double-blinded, parallel, randomized, sham-controlled trial: cerebellar stimulation group (CbSG), M1 stimulation group (MSG) and sham stimulation group (SSG). A single session of anodal tDCS with an intensity of 2 mA for a duration of 20 min was administered in addition to gait and balance training based on virtual reality using an Xbox 360 with Kinect. Balance, gait, cognition and risk of fall were assessed using outcome measures before intervention (T0), immediately after intervention (T1) and an hour after intervention (T2).

RESULTS

Across group analysis of all outcome measures showed statistically non-significant results (p > .05) except for Six Minute Walk Test (p value T0 = .003, p value T1 = .025, p value T2 = .016). The training effect difference showed a significant difference in balance, gait and cognition, as well as cerebral and cerebellar stimulation, in comparison to sham stimulation (p < .05). The risk of falls remained unaffected by any stimulation (p > .05).

CONCLUSIONS

In addition to Xbox Kinect-based rehabilitation training, a single session of anodal tDCS to the M1 or cerebellum may be beneficial for improving lower limb function, balance and gait performance.

Accelerometry in the Functional Assessment of Balance in People with Stroke: A Systematic Review

Balance disturbances in people with lived experience of stroke affect activities of daily living and social participation, so assessing them is essential to know the level of functional independence. Accelerometers are electronic devices that allow kinematic variables of balance to be recorded and are a tool of great interest in the assessment of functional balance. To determine the validity and reliability of, as well as the most performed protocols using accelerometers in the functional assessment of balance in people with experience of stroke, a systematic search of articles published in the electronic databases PubMed, Scopus, the Web of Science, the Cochrane Library, the PEDro and the Virtual Health Library from Spain was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. We used QUADAS-2 to assess the quality of the included studies. Eight studies met the inclusion criteria, two studied reliability and validity, two studied reliability and four studied the validity of accelerometers in the assessment of balance in people with stroke. All studies indicated the kind of accelerometer, localization on the body, tests and outcome variables. The results indicate that accelerometers show excellent reliability values in the assessment of balance in people who had a prior stroke and disparate results in terms of validity. Triaxial accelerometers were most used, and the 4th and 5th lumbar and 1st and 2nd sacral vertebrae were the body areas most used for their placement.

Effect of tibial nerve mobilization on balance & gait functions in subjects with subclinical diabetic neuropathy: A randomized clinical trial

Introduction

With advancing age, balance control diminishes as a result of cognitive impairment, decreased muscle strength, and impairment in visual, vestibular, and somatosensory systems. Besides aforesaid factors, the addition of diabetes to all these leads to balance and gait-related issues such as falls and fall-related injuries. Impaired balance and gait performance in diabetics are primarily attributed to the diminished sensory function of the foot and ankle region owing to diabetic neuropathy. The purpose of this study was to explicitly examine the impact of neural mobilization on the balance & gait functions of subjects having subclinical diabetic neuropathy.

Methods

40 individuals with subclinical diabetic neuropathy, ranging in age from 50 to 75 years, were assigned to two groups at random: Group 1 received the concurrent application of Tibial nerve mobilization and Balance-Gait training whereas Group 2 received only Balance-Gait training. The therapy was administered five times each week, for four weeks. On the first and last day of treatment, measurements of VPT, BBS, TUG, and DGI were taken from each subject.

Results

The results of the study found that post neural mobilization and Balance-Gait training, scores of VPT, BBS, DGI, and TUG showed improvement but it was not significant. As it is evident that diabetic neuropathy is progressive in nature, even small changes can be helpful.

Conclusion

Neural mobilization integrated with balance-gait training of subclinical diabetic neuropathic individuals resulted in improved sensory functions along with enhanced balance-gait functions.

The Functional Balance Ability Measure: A Measure of Balance Across the Spectrum of Functional Mobility in Persons Post-Stroke

Objective

To determine whether the measurement properties of an instrument that combines items from the Berg Balance Scale (BBS) and the Functional Gait Assessment (FGA) called the Functional Balance Ability Measure (FBAM) supports measuring balance across the functional mobility spectrum.

Design

Retrospective cohort.

Setting

Item-level data were from an archival research database.

Participants

Ambulatory individuals (N=93, BBS=50 [29-56], FGA=16 [0-30], Fugl-Meyer Assessment of Lower Extremities=27 [14-34], self-selected walking speed=0.4±0.2 m/s, mean age ± SD, 61.7±11.3y; 30.1% female) with chronic stroke (≥6 months).

Interventions

Not applicable.

Main Outcome Measures

Unidimensionality was evaluated with a principal components analysis (PCA) of residuals. FBAM rating-scale characteristics, item hierarchy, item and person fit, and person separation were investigated using the Andrich Rating Scale Model.

Results

PCA findings indicate the FBAM is sufficiently unidimensional. Rating scale structure was appropriate without modifying the original BBS and FGA scoring systems. Item hierarchy aligned with clinical and theoretical predictions (hardest item: FGA-gait with narrow base of support, easiest item: BBS-sitting unsupported). One item (BBS-standing on 1 foot) misfit, however, removal marginally affected person measures and model statistics. The FBAM demonstrated high person reliability (0.9) and 6 people (∼6%) misfit the expected response pattern. The FBAM separated participants into 4 statistically distinct strata, without a floor or ceiling effect.

Conclusions

The FBAM is a unidimensional measure for balance ability across a continuum of functional tasks. Rating-scale characteristics, item hierarchy, item and person fit, and person separation support the FBAM's measurement properties in persons with chronic stroke. Future work should investigate measurement with fewer items and whether the FBAM addresses barriers to adoption of standardized balance measures in clinical practice.

Yoga in the Rehabilitation of Post-Stroke Sequelae: A Non-Inferiority Randomized Controlled Trial

Introduction: Stroke survivors can experience various consequences that affect their physical and psychological balance. Yoga seems to be relevant for this population as it allows to work on both the body and the mind. The first objective of this study was to investigate the non-inferiority of yoga compared with conventional physical activity in improving physical function in patients with chronic post-stroke sequelae. The secondary objective was to investigate the superiority of yoga in improving the mental health of these patients. Methods: A randomized controlled trial was conducted. Thirty-six patients were randomized into two groups to practice a yoga program (YOG'AVC) or the Fitness and Mobility Exercise (FAME) program. Patients were assessed in a blinding mode pre- (T0) and post-program (T1) and 3-4 months after completion (T2). The physical assessments were the Berg Balance Scale, timed up and go test, 6-minute walk test, and quadriceps strength measured by hand-held dynamometer. Questionnaire assessments were: Activities-specific Balance Confidence Scale-Simplified, State-Trait Anxiety Inventory, Beck's Depression Inventory, and the Reintegration to Normal Living Index. Results: The YOG'AVC program was not inferior to the FAME program in improving balance, functional mobility and muscle strength. Both groups showed significant improvement (p < 0.05) between T0 and T1 in their anxiety, depression, and reintegration to normal life scores, with no significant difference between groups. Discussion: Both programs seem to be valuable in improving the physical abilities and psychological well-being of chronic post-stroke patients. However, further studies are required to confirm the difference between these programs.

A systematic review examining the effect of vitamin D supplementation on functional outcomes post-stroke

OBJECTIVE

The objective of this systematic review was to explore the effect of vitamin D supplementation on functional outcomes (motor function, mobility, activities of daily living and stroke impairment) among individuals post-stroke (PROSPERO CRD42022296462).

DATA SOURCES

MEDLINE, PsycINFO, EMBASE, and CINAHL were searched for all articles published up to March 5, 2023.

METHODS

Only interventional studies assessing vitamin D supplementation compared to placebo or usual care in adult stroke patients were selected. After duplicate removal, 2912 studies were screened by two independent reviewers. A total of 43 studies underwent full text review; 10 studies met inclusion criteria (8 randomized controlled trials and 2 non-randomized studies of intervention). Data were extracted by two independent reviewers using Covidence software. Motor function (Brunnstrom Recovery Stage, Berg Balance Score), mobility (Functional Ambulation Category), activities of daily living (Barthel Index, Functional Independence Measure) and stroke impairment (modified Rankin Scale, National Institutes for Health Stroke Severity, Scandinavian Stroke Severity) were the outcome measures of interest reported in the included studies.

RESULTS

In total, 691 patients were studied for which 11 of 13 outcome measures showed improvement with vitamin D supplementation.

CONCLUSIONS

The majority of studies showed a statistical improvement in motor function, mobility, and stroke impairment with vitamin D supplementation; however, the evidence did not support an improvement in activities of daily living with treatment. Despite this, there may not be clinical significance. Strong, methodologically sound, randomized controlled trials are required to verify these findings.

Selective Tibial Neurotomy Outcomes for Spastic Equinovarus Foot: Patient Expectations and Functional Assessment

BACKGROUND

Spastic equinovarus foot (SEF) is a common dysfunctional foot posture after stroke that impairs balance and mobility. Selective tibial neurotomy (STN) is a simple but underutilized surgical option that can effectively address critical aspects of SEF and thereby provide enduring quality of life gains. There are few studies that examine both functional outcomes and patient satisfaction with this treatment option.

OBJECTIVE

To elucidate the patient goals that motivated their decision to undergo the procedure and compare subjective and objective changes in balance and functional mobility as a consequence of surgery.

METHODS

Thirteen patients with problematic SEF who had previously failed conservative measures were treated with STN. Preoperative and postoperative (on average 6 months) assessments evaluated gait quality and functional mobility. In addition, a custom survey was conducted to investigate patient perspectives on STN intervention.

RESULTS

The survey showed that participants who opted for STN were dissatisfied with their previous spasticity management. The most common preoperative expectation for STN treatment was to improve walking, followed by improving balance, brace comfort, pain, and tone. Postoperatively, participants rated the improvement in their expectations and were, on average, 71 on a 100-point scale, indicating high satisfaction. The gait quality, assessed with the Gait Intervention and Assessment Tool, improved significantly between preoperative and postoperative assessment (M = -4.1, P = .01) with a higher average difference in stance of -3.3 than in swing -0.5. Improvement in both gait endurance (M = 36 m, P = .01) and self-selected gait speed (M = .12 m/s, P = .03) was statistically significant. Finally, static balance (M = 5.0, P = .03) and dynamic balance (M = 3.5, P = .02) were also significantly improved.

CONCLUSION

STN improved gait quality and functional mobility and was associated with high satisfaction in patients with SEF.

[Incidence, circumstances and consequences of falls in subjects with stroke: One year of follow-up]

INTRODUCTION

Falls are among the most frequent complications following stroke (CVA), and have a negative impact on rehabilitation.

OBJECTIVES

To study the incidence, circumstances, and consequences of falls in stroke patients up to 12months after starting outpatient kinetic treatment.

MATERIALS AND METHODS

Prospective design, case series. Consecutive sampling. Patients admitted to the day hospital between June 2019 and May 2020. Included: adults with a diagnosis of first supratentorial stroke and functional ambulatory category score ≥3.

EXCLUSION CRITERIA

other condition affecting locomotion.

MAIN VARIABLES

number of falls, circumstances, and consequences. Clinical, demographic, and functional characteristics were measured.

RESULTS

Twenty-one subjects were included, 13 suffered at least one fall. The subjects reported 41 falls: 15 were to the most affected side, 35 inside the home, 28 without the indicated equipment, they were alone when the event occurred on 29 occasions, and in two situations medical assistance was required. There were statistically significant differences (P<.05) in functional performance (balance, gait velocity) between those who fell and those who did not. No significant differences were found between gait endurance and falls.

CONCLUSION

More than half suffered a fall, alone, to the weaker side, and without the appropriate equipment. With this information the incidence could be reduced by preventive measures.

Effects of Power Training on Functional Capacity Related to Fall Risk in Older Adults: A Systematic Review and Meta-analysis

OBJECTIVE

Functional capacity is 1 of the main risk factors for falls among older adults. The aim of this systematic review and meta-analysis was to determine the effect of power training on functional capacity test (FCT) related to fall risk in older adults.

DATA SOURCES

Systematic searches were conducted in 4 databases, including PubMed, Web of Science, Scopus, and SPORTDiscus, from inception to November 2021.

STUDY SELECTION

Randomized controlled trials (RCTs) assessing the effect of power training on functional capacity compared with another type of training program or control group in older adults with the ability to exercise independently.

DATA EXTRACTION

Two independent researchers evaluated eligibility and used the PEDro scale to assess risk of bias. The information extracted was related to article identification (authors, country and year of publication), participant characteristics (sample, sex, and age), strength training protocols (exercises/intensity/weeks), and the outcome of the FCT used related to fall risk. The Cochran Q statistic and I2 statistics was used to assess heterogeneity. Random-effects model were conducted to pool the effect sizes expressed as mean differences (MD).

DATA SYNTHESIS

Twelve studies (478 subjects) were selected for systematic review. A meta-analysis comprised 6 studies (217 subjects) where the outcome measure was the 30-second Sit to Stand (30s-STS) test, and another comprised 4 studies (142 subjects) where the outcome measure was the timed Up and Go (TUG) test. There was an improvement in performance in favor of the experimental group in both the TUG subgroup (MD -0.31 s; 95% CI -0.63, 0.00 s; P=.05), and the 30s-STS subgroup (MD 1.71 reps; 95% CI -0.26, 3.67 reps; P=.09).

CONCLUSIONS

In conclusion, power training increases functional capacity related to fall risk further than other types of exercise in older adults.

Reliability, Concurrent Validity, and Minimal Detectable Change of Timed Up and Go Obstacle Test in People With Stroke

OBJECTIVE

The aims of this study were to investigate the psychometric property of the timed Up and Go Obstacle (TUGO) test in people with stroke.

DESIGN

Cross-sectional design.

SETTING

University based neurorehabilitation laboratory.

PARTICIPANTS

Twenty-eight people with stroke and 30 healthy older adults.

INTERVENTION

Not Applicable.

OUTCOME MEASURES

The TUGO (obstacle heights: 0, 5, 17 cm) test completion times, Fugl-Meyer Assessment (FMA) score, ankle dorsiflexor and plantarflexor muscle strength, Berg Balance Scale (BBS) score, Narrow Corridor Walking Test (NCWT) completion time, timed Up and Go (TUG) test completion time, and Community Integrated Measure.

RESULTS

Excellent inter-rater (intraclass correlation coefficient [ICC]=0.999-1.000) and test-retest reliabilities (ICC=0.917-0.975) were found for TUGO test completion times for all obstacle heights. The TUGO test completion times for all obstacle heights were significantly correlated with NCWT and TUG test completion times (r=0.817-0.912). Only TUGO test completion times for 0 and 5 cm obstacle heights showed significant correlations with BBS scores (r=-0.518 to -0.534), while the TUGO test completion time for the 17 cm obstacle height correlated significantly with FMA scores. The minimal detectable change and optimal cut-off values for TUGO test completion times for the 0, 5, and 17 cm obstacle heights were 2.54, 3.60, and 3.07 s, and 14.69, 14.76, and 16.10 s, respectively.

CONCLUSION

The TUGO test is a reliable, valid, and easy-to-administer clinical measure to discriminate between people with stroke and healthy older adults.

Intrarater and interrater reliability of the dynamic gait index in post stroke patients with eye movement disorders

BACKGROUND

The Dynamic Gait Index (DGI) is a useful tool that has been evaluated for its reliability in patients with vestibular disorders, elderly people and, in chronic stroke population. Present study was aimed to evaluate the intrarater and interrater reliability of the DGI to measure dynamic balance and gait performance in stroke patients with eye movement disorders.

METHODS

A sample of 30 stroke patients suffering from eye movement disorders were recruited. Two Physical therapists assessed the intrarater and interrater reliability of the DGI in two testing sessions three days apart. In the later session, two raters assessed the patients' performance simultaneously on the DGI. The reliability was calculated using the intra-class correlation coefficient (ICC2, 1). Standard error of measurement (SEM) and minimal detectable change (MDC95) at 95% confidence interval were also calculated. A significance level was set at p-value <0.05.

RESULTS

The (ICC2, 1) for intrarater and interrater reliability of total DGI scores was 0.86 and 0.91 respectively. While (ICC2, 1) for intrarater and interrater reliability of individual items ranged from 0.73 to 0.91 to 0.73-0.93, respectively. The (SEM) and (MDC95) for intrarater reliability of total DGI scores were 0.76 and 2.10, respectively. Corresponding values for interrater reliability were 0.62 and 1.71, respectively.

CONCLUSIONS

The DGI is a reliable tool for evaluating the dynamic balance and gait performance in stroke patients with eye movement disorders. This tool showed good to excellent intrarater and interrater reliability of total DGI scores and moderate to good intrarater and interrater reliability of individual items of the DGI.

Validity, reliability and minimal detectable change of Mini-BESTest Turkish version in neurological disorders

AIMS

It is aimed to investigate the psychometric properties of Mini-BESTestTR in Turkish patients with neurological disorders.

METHODS

A total of 61 people between the ages of 42 and 80, who were patients with Parkinson's disease, stroke or multiple sclerosis for more than 1 year, were included in the study. For inter-rater reliability, two independent researchers applied the scale two times within 5 days for test-retest reliability. The relationship of mini-BESTestTR with Berg Balance Scale (BBS) to assess concurrent validity, and Timed Get up and Go (TUG), Functional Reach Test (FRT) and Functional Ambulation Classification (FAC) for convergent validity was investigated.

RESULTS

The scores of the two evaluators were within the range of agreement (mean = - 0.278 ± 1.484, p > 0.05), and the Mini-BESTestTR had excellent inter-rater reliability [ICC (95% CI) = 0.989 (0.981-0.993)] and test-retest reliability [ICC (95% CI) = 0.998 (0.996-0.999)]. Mini-BESTestTR had a strong correlation with BBS (r = 0.853, p < 0.001) and TUG (r =  - 0.856, p < 0.001), had a moderate correlation with FAC (r = 0.696, p < 0.001) and FRT (r = 0.650, p < 0.001).

CONCLUSIONS

Mini-BESTestTR showed significant correlations with other balance assessment measures, and concurrent and convergent validity of Mini-BESTestTR was demonstrated when administered to a sample of patients with chronic stroke, Parkinson's disease and multiple sclerosis.

Effect of physical exercise on fear of falling in patients with stroke: A systematic review and meta-analysis

OBJECTIVE

To consolidate the evidence on the effect of physical exercise on fear of falling in individuals with stroke.

DATA SOURCES

PubMed, CINAHL, Cochrane Database and MEDLINE.

METHODS

An extensive database search was conducted to identify the randomised controlled trials that examined the effect of physical exercise on fear of falling post-stroke. Grading of Recommendation, Assessment, Development and Evaluation (GRADE) was used to assess the quality of evidence for each meta-analysis.

RESULTS

Fourteen trials totalling 1211 participants were included in this review. Thirteen of these (1180 participants) were included in the meta-analyses. In the primary analysis, very low-quality evidence suggested that exercise reduced fear of falling post-stroke (standardized mean difference (SMD) 0.48; 95% confidence interval (CI) 0.23 to 0.72). The effect was diminished at three- to six-month follow-up after exercise training ended (SMD -0.09; 95% CI -0.27 to 0.10; high-quality evidence). In the sensitivity analyses, the treatment effect was more pronounced in individuals with a lower baseline Berg balance score (BBS ≤45; SMD 0.53; 95%CI 0.17 to 0.88) and for those trials with exercise frequency of ≥3 sessions per week (SMD 0.70; 95%CI 0.39 to 1.01). Compared with circuit-based training consisting of a combination of walking, balance and strengthening exercises (SMD 0.27; 95% CI -0.09 to 0.63), walking programmes seemed to generate a larger effect on fear of falling (SMD 1.06; 95%CI 0.43 to 1.70).

CONCLUSION

Physical exercise was beneficial for reducing fear of falling in individuals with stroke, particularly those with poorer balance ability.

Overestimation associated with walking and balance function in individuals diagnosed with a stroke

BACKGROUND

An estimation error is the difference between motor imagery and actual motor time. Previous studies have reported that overestimation (motor imagery time < actual motor time) is related to physical functions in healthy individuals. However, this finding is unclear among individuals diagnosed with a stroke.

OBJECTIVE

We investigated whether overestimation is related to physical function in individuals diagnosed with a stroke.

METHODS

This study included 71 individuals diagnosed with a stroke (mean age, 67.2 ± 13.4 years; mean time since stroke, 68.4 ± 44.7 days). Imagined timed up and go test (iTUGT) was performed to assess the estimation error. First, the iTUGT was performed; subsequently, the TUGT was performed. The estimation error was calculated by subtracting the TUGT from the iTUGT, with two standard deviations (2 SDs) being calculated. Furthermore, patients were classified into appropriate estimation (AE, within ±2 SD) and overestimation (OE, over -2 SD) groups. Both groups were tested using the estimation error, iTUGT, TUGT, Berg Balance Scale (BBS), and Brunnstrom Recovery Stage (BRS). Subsequently, a correlation analysis was performed.

RESULTS

The OE group had a significantly higher estimation error than the AE group (OE: -7.08 ± 6.87 s, AE: -0.29 ± 1.53 s, P < .001). Moreover, the OE group had significantly lower TUGT and BBS than the AE group. The estimation error was correlated with the TUGT, BBS, and lower-limb BRS (ρ = -0.454, 0.431, 0.291, respectively; P < .05).

CONCLUSIONS

Overestimation was associated with TUGT and balance function in individuals diagnosed with a stroke.

Using the RE-AIM framework to evaluate physical activity-based fall prevention interventions in older adults with chronic conditions: A systematic review

Falls are a serious public health problem, especially for older adults with chronic conditions. The purpose of this systematic review was to evaluate the translational potential of physical activity-based balance interventions for older adults with common chronic conditions guided by the Reach, Effectiveness/Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework. Databases were searched (2011-2021) to identify studies with physical activity-based fall prevention interventions for older adults with chronic conditions. Data were collected using the RE-AIM coding guide and Mixed Methods Appraisal Tool for evidence quality. The search yielded 122 articles, of which 14 distinct studies were included. The most reported RE-AIM dimensions across the studies were Reach (46.2%) and Implementation (40.5%), with Effectiveness/Efficacy (29.4%), Adoption (2.0%), and Maintenance (5.4%) being the least reported. Studies were largely conducted in controlled research environments with minimal staff involvement and without long-term follow-up periods. While studies found that physical activity-based programs were effective in improving balance, information on representativeness and adoption/maintenance of programs was lacking. Studies included sufficient details about the intervention (content, dosage, progression). External validity RE-AIM indicators were reported less frequently than internal validity indicators. The studies were of moderate quality overall. Studies often lacked information on indicators critical for understanding how to implement these programs. This review signals the need to investigate the translation of these interventions from controlled research settings to clinical settings to improve the public impact of fall prevention for this population.

Fallers after stroke: a retrospective study to investigate the combination of postural sway measures and clinical information in faller's identification

Background

Falls can have devastating effects on quality of life. No clear relationships have been identified between clinical and stabilometric postural measures and falling in persons after stroke.

Objective

This cross-sectional study investigates the value of including stabilometric measures of sway with clinical measures of balance in models for identification of faller chronic stroke survivors, and the relations between variables.

Methods

Clinical and stabilometric data were collected from a convenience sample of 49 persons with stroke in hospital care. They were categorized as fallers (N = 21) or non-fallers (N = 28) based on the occurrence of falls in the previous 6 months. Logistic regression (model 1) was performed with clinical measures, including the Berg Balance scale (BBS), Barthel Index (BI), and Dynamic Gait Index (DGI). A second model (model 2) was run with stabilometric measures, including mediolateral (SwayML) and anterior-posterior sway (SwayAP), velocity of antero-posterior (VelAP) and medio-lateral sway (VelML), and absolute position of center of pressure (CopX abs). A third stepwise regression model was run including all variables, resulting in a model with SwayML, BBS, and BI (model 3). Finally, correlations between independent variables were analyzed.

Results

The area under the curve (AUC) for model 1 was 0.68 (95%CI: 0.53-0.83, sensitivity = 95%, specificity = 39%) with prediction accuracy of 63.3%. Model 2 resulted in an AUC of 0.68 (95%CI: 0.53-0.84, sensitivity = 76%, specificity = 57%) with prediction accuracy of 65.3%. The AUC of stepwise model 3 was 0.74 (95%CI: 0.60-0.88, sensitivity = 57%, specificity = 81%) with prediction accuracy of 67.4%. Finally, statistically significant correlations were found between clinical variables (p < 0.05), only velocity parameters were correlated with balance performance (p < 0.05).

Conclusion

A model combining BBS, BI, and SwayML was best at identifying faller status in persons in the chronic phase post stroke. When balance performance is poor, a high SwayML may be part of a strategy protecting from falls.

Enhancing patient self-management after a first stroke: An application of the wearable devices and the health management platform

BACKGROUND

Post-stroke disability restricts a patient's physical activity, affects the patient's quality of life, and leads to higher medical costs. Therefore, it is essential to promote patients' continuous exercise during this period of recovery.

OBJECTIVE

This study aimed to verify the effectiveness of applying a health management platform combined with wearable devices to enhance stroke patients' self-management of recovery and to allow comparisons with active care intervention management.

METHOD

This quasi-experimental study aimed at examining those participants who had sustained a stroke for the first time. A 90-day experiment was implemented with the intervention of monitoring and active care from the researchers who also interviewed the selected participants at the end of the study. A total of 26 participants were examined (14 in the experimental group and 12 in the control group).

RESULT

The participants in the experimental group made significant progress between the pre- and post-tests. Firstly, their six-minute walking distance improved by 89.5 m (p < 0.001). Secondly, their sit-to-stand transfers in 60 s improved 2.85 times (p = 0.017), and their Berg balance test improved by 6.36 points (p = 0.003). Finally, the Partners in Health scale (PIH) scores also improved. According to the data collected in the interviews, the researchers' intervention improved the patients' self-management ability.

CONCLUSION

The short-term physical performance in the experimental group after the intervention was better than that in the control group. In clinical practice, it is suggested that continuous interaction between medical staff and patients be sustained while applying wearable devices to promote the patient's self-management ability.

The impact of visuospatial and executive function on activity performance and outcome after robotic or conventional gait training, long-term after stroke-as part of a randomized controlled trial

INTRODUCTION

Visuospatial and executive impairments have been associated with poor activity performance sub-acute after stroke. Potential associations long-term and in relation to outcome of rehabilitation interventions need further exploration.

AIMS

To explore associations between visuospatial and executive function and 1) activity performance (mobility, self-care and domestic life) and 2) outcome after 6 weeks of conventional gait training and/or robotic gait training, long term (1-10 years) after stroke.

METHODS

Participants (n = 45), living with stroke affecting walking ability and who could perform the items assessing visuospatial/executive function included in the Montreal Cognitive Assessment (MoCA Vis/Ex) were included as part of a randomized controlled trial. Executive function was evaluated using ratings by significant others according to the Dysexecutive Questionnaire (DEX); activity performance using 6-minute walk test (6MWT), 10-meter walk test (10MWT), Berg balance scale, Functional Ambulation Categories, Barthel Index and Stroke Impact Scale.

RESULTS

MoCA Vis/Ex was significantly associated with baseline activity performance, long-term after stroke (r = .34-.69, p < .05). In the conventional gait training group, MoCA Vis/Ex explained 34% of the variance in 6MWT after the six-week intervention (p = 0.017) and 31% (p = 0.032) at the 6 month follow up, which indicate that a higher MoCA Vis/Ex score enhanced the improvement. The robotic gait training group presented no significant associations between MoCA Vis/Ex and 6MWT indicating that visuospatial/executive function did not affect outcome. Rated executive function (DEX) presented no significant associations to activity performance or outcome after gait training.

CONCLUSION

Visuospatial/executive function may significantly affect activity performance and the outcome of rehabilitation interventions for impaired mobility long-term after stroke and should be considered in the planning of such interventions. Patients with severely impaired visuospatial/executive function may benefit from robotic gait training since improvement was seen irrespective of visuospatial/executive function. These results may guide future larger studies on interventions targeting long-term walking ability and activity performance.

Effects of Gaze Stabilization Exercises on Gait, Plantar Pressure, and Balance Function in Post-Stroke Patients: A Randomized Controlled Trial

This study aims to explore the effects of gaze stabilization exercises (GSEs) on gait, plantar pressure, and balance function in post-stroke patients (≤6 months). Forty post-stroke patients were randomly divided into an experimental group (n = 20) and a control group (n = 20). The experimental group performed GSEs combined with physical therapy, while the control group only performed physical therapy, once a day, 5 days a week, for 4 weeks. The Berg Balance Scale (BBS) was used to test the balance function and the risk of falling, which was the primary outcome. The Timed Up and Go test (TUGT) evaluated the walking ability and the fall risk. The envelope ellipse area and the plantar pressure proportion of the affected side were used to measure the patient’s supporting capacity and stability in static standing. The anterior−posterior center of pressure displacement velocity was used to test the weight-shifting capacity. Compared to the control group, the swing phase of the affected side, swing phase’s absolute symmetric index, envelope ellipse area when eyes closed, and TUGT of the experimental group had significantly decreased after GSEs (p < 0.05); the BBS scores, TUGT, the anterior−posterior COP displacement velocity, and the plantar pressure proportion of the affected side had significantly increased after 4 weeks of training (p < 0.05). In conclusion, GSEs combined with physical therapy can improve the gait and balance function of people following stroke. Furthermore, it can enhance the weight-shifting and one-leg standing capacity of the affected side, thus reducing the risk of falling.

Berg Balance Scale is a Valid Measure for Plan Interventions and for Assessing Changes in Postural Balance in Patients with Stroke

OBJECTIVES

After confirming the measurement properties of the Berg Balance Scale (BBS) in patients with stroke by conducting a Rasch analysis, this study sought: (i) to generate a keyform as a tool for goal-setting and intervention-planning; and (ii) to determine the appropriate strata for separating patients' postural balance ability.

DESIGN

Methodological analyses of cross-sectional study data.

PATIENTS

A pooled sample of 156 patients with stroke: mean (standard deviation) age 74.4 (12.9) years.

METHODS

This study evaluated the BBS's rating scale structure, unidimensionality, and measurement accuracy (0: unable to perform or requiring help, to 4: normal performance) and then generated a keyform and strata.

RESULTS

The BBS rating scale fulfilled the category functioning criteria. Principal component analysis of standardized residuals confirmed the unidimensionality of the test. All items fit the Rasch analysis. Person ability-item difficulty matching was good. Person reliability was 0.96, and the patients were divided into 9 strata. The keyform for the BBS will enable clinicians and investigators to estimate patients' postural balance ability and monitor their progress.

CONCLUSION

The BBS has strong measurement properties. This study generated both a keyform that can contribute to clinicians' decision-making in goalsetting and intervention-planning and strata that can facilitate understanding of patients' abilities.

Augmented reality for stroke rehabilitation during COVID-19

BACKGROUND

The lack of the rehabilitation professionals is a global issue and it is becoming more serious during COVID-19. An Augmented Reality Rehabilitation System (AR Rehab) was developed for virtual training delivery. The virtual training was integrated into the participants' usual care to reduce the human trainers' effort so that the manpower scarcity can be eased. This also resulted in the reduction of the contact rate in pandemics.

OBJECTIVE

To investigate the feasibility of the AR Rehab-based virtual training when integrated into the usual care in a real-world pandemic setting, by answering questions of whether the integrated trials can help fulfill the training goal and whether the trials can be delivered when resources are limited because of COVID-19.

METHODS

Chronic stroke participants were randomly assigned to either a centre-based group (AR-Centre) or a home-based group (AR-Home) for a trial consisting of 20 sessions delivered in a human-machine integrated intervention. The trial of the AR-Centre was human training intensive with 3/4 of each session delivered by human trainers (PTs/OTs/Assistants) and 1/4 delivered by the virtual trainer (AR Rehab). The trial of the AR-Home was virtual training intensive with 1/4 and 3/4 of each session delivered by human and virtual trainers, respectively. Functional assessments including Fugl-Meyer Assessment for Upper Extremity (FMA-UE) and Lower Extremity (FMA-LE), Functional Ambulation Category (FAC), Berg Balance Scale (BBS), Barthel Index (BI) of Activities of Daily Living (ADL), and Physical Component Summary (SF-12v2 PCS) and Mental Component Summary (SF-12v2 MCS) of the 12-Item Short Form Health Survey (SF-12v2), were conducted before and after the intervention. User experience (UX) using questionnaires were collected after the intervention. Time and human resources required to deliver the human and virtual training, respectively, and the proportion of participants with clinical significant improvement were also used as supplementary measures.

RESULTS

There were 129 patients from 10 rehabilitation centres enrolled in the integrated program with 39 of them were selected for investigation. Significant functional improvement in FMA-UE (AR-Centre: p = 0.0022, AR-Home: p = 0.0043), FMA-LE (AR-Centre: p = 0.0007, AR-Home: p = 0.0052), SF-12v2 PCS (AR-Centre: p = 0.027, AR-Home: p = 0.036) were observed in both groups. Significant improvement in balance ability (BBS: p = 0.0438), and mental components (SF-12v2 MCS: p = 0.017) were found in AR-Centre group, while activities of daily living (BI: p = 0.0007) was found in AR-Home group. Contact rate was reduced by 30.75-72.30% within AR-All, 0.00-60.00% within AR-Centre, and 75.00-90.00% within AR-Home.

CONCLUSION

The human-machine integrated mode was effective and efficient to reduce the human rehabilitation professionals' effort while fulfilling the training goals. It eased the scarcity of manpower and reduced the contact rate during the pandemics.

Effects of Compression Stockings on Body Balance in Hemiplegic Patients with Subacute Stroke

(1) Background: Stroke patients with hemiplegia have an increased risk of developing deep vein thrombosis (DVT). DVT increases the risk of life-threatening pulmonary embolism and is associated with poor prognosis. The early wearing of compression stockings can help prevent DVT. This study aimed to assess the impact of compression stockings on body balance in stroke patients with unilateral lower extremity muscle weakness; (2) Methods: Hemiplegic stroke patients in the subacute phase who were able to walk with assistance were recruited. The patients were divided into two groups: one group received rehabilitation treatment with compression stockings, and the other received treatment without compression stockings. The rehabilitation treatment involved hospitalization for 4 weeks, the Trunk Control Test (TCT), the Trunk Impairment Scale (TIS), and the Berg Balance Scale (BBS). The patients were evaluated before and 4 weeks after the start of treatment. The differences in BBS, TCT, and TIS before and after treatment between the two groups were compared; (3) Results: Altogether, 236 hemiplegic stroke patients were recruited. There was an improvement in body balance after treatment in both groups, and BBS, TCT, and TIS scores significantly increased in the group that received rehabilitation treatment with compression stockings; (4) Conclusions: In patients with hemiplegic stroke in the subacute period, rehabilitation while wearing compression stockings appears to improve body balance.

Validity and reliability of center of pressure measures to quantify trunk control ability in individuals after stroke in subacute phase during unstable sitting test

Objective

The objective of this study was to assess, for individuals with hemiparesis after a stroke in subacute phase, the validity and reliability of center of pressure (CoP) parameters measured during sitting balance on an unstable support.

Materials and methods

Thirty-two individuals after stroke were included in this observational study for validity and reliability (mean age: 64.34 ± 9.30y, 23 men, mean post-stroke duration: 55.64 ± 27days). Intra-Class Correlation (ICC) and Bland Altman plot assessed intra-rater reliability and inter-rater reliability of CoP parameters during unstable sitting balance test (anteroposterior or mediolateral imbalance). Validity was established by correlating CoP parameters with the Modified Functional Reach Test, trunk strength, Balance Assessment in Sitting and Standing and Timed Up and Go tests.

Results

The findings highlighted significant correlations between CoP parameters and trunk strength for anteroposterior seated destabilization. Good to excellent intra and inter-rater reliability (0.87 ≤ ICC ≤ 0.95) was observed for all CoP length parameters and CoP mean velocity in both mediolateral and anteroposterior imbalance conditions. CoP parameters for mediolateral unstable sitting condition were more reliable than for anteroposterior instability.

Conclusion

Trunk control assessment during unstable sitting position on a seesaw is a reliable test for assessing trunk control ability in individuals after a stroke. CoP length and mean velocity are found to be the best parameters.

•

Center of pressure values during anteroposterior perturbation is related to trunk strength.

•

Center of pressure length parameters have excellent intra-rater and inter-rater reliability in individuals after a stroke in subacute phase.

•

The reliability is better when the sitting instability is in mediolateral direction.

Potential of Whole-Body Vibration in Parkinson’s Disease: A Systematic Review and Meta-Analysis of Human and Animal Studies

Simple Summary

Exercise has shown to have a positive impact on both motor and non-motor functions in Parkinson’s Disease patients. However, particularly in later stages of the disease, reduced cognitive function and motor capacity may lead to an inability to stay physically active. Therefore, alternative strategies for patients with Parkinson’s Disease are necessary to minimize burden for patients, their families and public health care. Whole-Body Vibration could be such an alternative. Whole-Body Vibration is an exercise or treatment method in which subjects are exposed to a mechanical vibration while sitting, standing or exercising on a vibrating platform. Whole-Body Vibration is currently used for physiotherapy, sports and rehabilitation purposes. Whole-Body Vibration treatment is interesting because it affects both the body and brain. The potential of Whole-Body Vibration for, specifically, Parkinson’s Disease patients should be clarified for further application. For this purpose, we conducted an extensive systematic review of the articles investigating the effects of Whole-Body Vibrations (1) on animals and humans with Parkinson’s Disease and (2) on neuropathological Parkinson’s Disease mechanisms. The results show some potential of Whole-Body Vibration for Parkinson’s Disease patients. The recommendations provided by this review can be used by researchers and rehabilitative practitioners implementing Whole-Body Vibration as a treatment for Parkinson’s Disease patients.

Abstract

(1) Background: When the severity of Parkinson’s Disease (PD) increases, patients often have difficulties in performing exercises. Whole-Body Vibration (WBV) may be a suitable alternative. This systematic review aims to clarify if WBV shows potential as rehabilitative therapy for PD patients. (2) Methods: We searched several databases for controlled trials investigating the effects of WBV (1) on PD populations and (2) PD neuropathological mechanisms. We included both human and animal studies and performed meta-analyses. (3) Results: The studies on PD populations (14 studies) show an overall significant, but small, effect in favor of WBV (Hedges’ g = 0.28), for which the effects on stability (Hedges’ g = 0.39) and balance (Hedges’ g = 0.30) are the most prominent. The studies on the neuropathological mechanisms (18 studies) show WBV effects on neuroinflammation (Hedges’ g = –1.12) and several specific WBV effects on neurotransmitter systems, growth factors, neurogenesis, synaptic plasticity and oxidative stress. (4) Conclusions: The effects of WBV on human PD patients remains inconclusive. Nevertheless, WBV protocols with sufficient duration (≥3 weeks), session frequency (≥3 sessions/week) and vibration frequency (≥20 Hz) show potential as a treatment method, especially for motor function. The potential of WBV for PD patients is confirmed by the effects on the neuropathological mechanisms in mostly non-PD populations. We recommend high-quality future studies on both PD patients and PD mouse models to optimize WBV protocols and to examine the neuropathological mechanisms in PD populations.

Effects of constraint-induced movement therapy for the lower extremity among individuals post-stroke: A randomized controlled clinical trial

BACKGROUND: Stroke often leads to lower extremity impairments that significantly hinders functional recovery. OBJECTIVE: To investigate the effectiveness of constraint-induced movement therapy for the lower extremity (CIMT-LE) for improving balance and ambulation among people post-stroke. METHODS: A randomized controlled, single-blinded clinical trial was conducted. Participants were recruited and randomized into one of two groups: CIMT-LE group and control. Outcome measures were the Fugl-Meyer assessment of lower extremity, Berg balance scale, ten-meter walk test and six-minute walk test. Outcome measures were collected at baseline, following the conclusion of the therapeutic programs and after three months. RESULTS: 38 participants were enrolled in the study (19 in each group). No significant differences were found between groups at baseline. At the conclusion of therapeutic programs, both groups showed significant changes compared to baseline. However, changes seen in the CIMT-LE were clinically significant. Further, at three months following the conclusion of the program, the recorded improvements were retained by participants. CONCLUSION: A CIMT-LE program compared to an intensity-matched conventional program yielded significant clinical improvements among people post-stroke. These improvements were seen in lower extremity motor recovery, postural balance and gait speed. Furthermore, these improvements were retained three months following the conclusion of the therapeutic program.

Balance impairment in patients with moderate-to-severe traumatic brain injury: Which measures are appropriate for assessment?

Left untreated, balance impairment following moderate-to-severe traumatic brain injury (TBI) can be highly debilitating and hinder activities of daily life. To detect impairments, clinicians need appropriate assessment tools. The objective of this study was to evaluate the feasibility and utility of a battery of clinical balance assessments in adults with moderate-to-severe TBI within 6-months of injury. Thirty-seven adults with TBI [Glasgow Coma Scale score ≤ 12 (33 M/4 F) age 18–50 years] participated in balance testing. Assessments included the Balance Error Scoring System (BESS), National Institutes of Health Standing Balance Test (NIH-SBT), Functional Gait Assessment (FGA), Advanced Functional Gait Assessment (FGA-A), Tandem Gait Test (TGT), Berg Balance Scale (BBS), and Walking While Talking Test (WWTT). We identified pronounced ceiling effects on the BBS and FGA, two widely used clinical balance assessments. The NIH-SBT, WWTT, and FGA used in conjunction with the FGA-A, offered versatility in their capacity to assess patients across the balance severity spectrum. This study provides evidence to support a stepwise approach to balance assessment that can be adapted to the broad range of balance ability found in moderate-to-severe TBI.

Both diffusion and lobule magnetic resonance imaging analyses and common clinical measures of motor and cognitive function were used to examine structure-function relationships in the cerebellum.

RESULTS

PwMS demonstrate significantly worse motor and cognitive function than controls, including weaker strength, slower walking, and poorer performance on the Symbol Digit Modalities Test, but demonstrate no differences in cerebellar volume. However, PwMS demonstrate significantly worse diffusivity (mean diffusivity: P=.0003; axial diffusivity: P=.0015; radial diffusivity: P=.0005; fractional anisotropy: P=.016) of the superior cerebellar peduncle, the primary output of the cerebellum. Increased volume of the motor lobules (I-V, VIII) was significantly related to better motor (P<.022) and cognitive (P=.046) performance, and increased volume of the cognitive lobules (VI-VII) was also related to better motor (P<.032) and cognitive (P=.008) performance, supporting the role of the cerebellum in both motor and cognitive functioning.

CONCLUSIONS

These data highlight the contributions of the cerebellum to both motor and cognitive function in PwMS. Using novel neuroimaging techniques to examine structure-function relationships in PwMS improves our understanding of individualized differences in this heterogeneous group and may provide an avenue for targeted, individualized rehabilitation aimed at improving cerebellar dysfunction in MS.

Effect of Robot-Assisted Training on Unilateral Spatial Neglect After Stroke: Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Several studies have shown that robotic devices can effectively improve motor function in stroke patients through limb activation. However, the effects of robot-assisted therapy on perceptual deficits after stroke is unclear.

OBJECTIVE

This review aimed to evaluate the effectiveness of robotic limb activation in patients with unilateral spatial neglect (USN) after stroke.

METHODS

In this systematic review, a literature search was performed using MEDLINE, EMBASE, CENTRAL, CINAHL, and LILACS databases without language restrictions. Randomized controlled trials (RCTs) and quasi-RCTs of robot-assisted therapy for USN after stroke were selected. Two reviewers independently assessed the risk of bias and certainty of the evidence of the included studies.

RESULTS

A total of 630 studies were identified, including five studies for qualitative synthesis and four meta-analyses. The results of RCTs comparing robotic limb activation with a control group suggested an improvement in the degree of USN measured by the line bisection test (standardized mean difference [SMD], -0.64; 95% confidence interval [CI], -1.13 to -0.15; P = .01). There were no differences between the groups in the motor-free visual perception test 3rd edition (SMD, 0.27; 95% CI, -0.25-0.79; P = .31), star cancellation test (SMD, 0.26; 95% CI, -0.42-0.94; P = .54), Albert's test (SMD, -0.67; 95% CI, -2.01-0.66; P = .32), and Catherine Bergego Scale (SMD, -0.81; 95% CI, -2.07-0.45; P = .21).

CONCLUSION

The study demonstrated that limb activation through robotic therapy can improve midline perception. However, there was no impact on tasks assessing visual scanning, functionality, or activities of daily living.

Interactive Videogame Improved Rehabilitation Motivation and Walking Speed in Chronic Stroke Patients: A Dual-Center Controlled Trial

Objective: This study aimed to evaluate the effectiveness of interactive video games (IVGs) in rehabilitation motivation and walking and balance abilities in chronic stroke patients. Materials and Methods: In this dual-center controlled trial, 24 chronic stroke patients from rehabilitation centers A and B were randomly assigned to an experimental (IVGs + traditional neurodevelopment treatment [TNT], n = 12) or a control group (walking training + TNT, n = 12). The patients in both the groups underwent TNT for 4 weeks (5 days/week) before undergoing either IVGs or walking training (4 weeks, 3 days/week) depending on the group. The primary and secondary outcomes were rehabilitation motivation and the Berg Balance Scale (BBS) score, Functional Reach Test (FRT) performance, and walking speed (WS), respectively. Results: The patients in both the groups showed significant increase in the BBS score, FRT performance, and WS; however, the experimental group showed more significant improvements in rehabilitation motivation (P = 0.02, η² = 0.415) and WS (P = 0.05, η² = 0.333) than the patients in the control group. Conclusion: This study suggests that the IVGs in combination with TNT provide effective rehabilitation motivation in chronic stroke patients. Clinical Trial Registration number: KCT0003408.

Effects of Robot-Assisted Gait Training with Body Weight Support on Gait and Balance in Stroke Patients

This study investigated the effects of robot-assisted gait training with body weight support on gait and balance in stroke patients. The study participants comprised 24 patients diagnosed with stroke. Patients were randomly assigned to four groups of six: robot A, B, C, and non-robot. The body weight support (BWS) for the harness of the robot was set to 30% of the patient’s body weight in robot group A, 50% in robot group B, and 70% in robot group C. All experimental groups received robot-assisted gait training and general physical therapy. The non-robot group underwent gait training using a p-bar, a treadmill, and general physical therapy. The intervention was performed for 30 min a day, five times a week, for 6 weeks. All participants received the intervention after the pre-test. A post-test was performed after all of the interventions were completed. Gait was measured using a 10 m Walking test (10MWT) and the timed up and go (TUG) test. Balance was assessed using the Berg Balance Scale (BBS). Robot groups A, B, and C showed significantly better 10MWT results than did the non-robot group (p < 0.5). TUG was significantly shorter in robot groups A, B, and C than in the non-robot group (p < 0.5). The BBS scores for robot group A improved significantly more than did those for robot groups B and C and the non-robot group (p < 0.5), indicating that robot-assisted gait training with body weight support effectively improved the gait of stroke patients.

Influence of Core-Stability Exercises Guided by a Telerehabilitation App on Trunk Performance, Balance and Gait Performance in Chronic Stroke Survivors: A Preliminary Randomized Controlled Trial

Stroke is one of the main causes of disability. Telerehabilitation could face the growing demand and a good strategy for post-stroke rehabilitation. The aim of this study is to examine the possible effects of therapeutic exercises performed by an App on trunk control, balance, and gait in stroke survivors. A preliminary 12-week randomized controlled trial was developed. Thirty chronic stroke survivors were randomly allocated into two groups. Both groups performed conventional physiotherapy, in addition to, the experimental group (EG) had access to a telerehabilitation App to guide home-based core-stability exercises (CSE). Trunk performance was measured with the Spanish-Trunk Impairment Scale (S-TIS 2.0) and Spanish-Function in Sitting Test. Balance and gait were measured with Spanish-Postural Assessment Scale for Stroke patient, Berg Balance Scale and an accelerometer system. In EG was observed an improvement of 2.76 points in S-TIS 2.0 (p = 0.001). Small differences were observed in balance and gait. Adherence to the use of the App was low. CSE guided by a telerehabilitation App, combined with conventional physiotherapy, seem to improve trunk function and sitting balance in chronic post-stroke. Active participation in the rehabilitation process should be increased among stroke survivors. Further confirmatory studies are necessary with a large sample size.

Dance as an Intervention to Reduce Fall Risk in Older Adults: A Systematic Review With a Meta-Analysis

The purpose of this study was to summarize the evidence from randomized clinical trials on the effects of dance on fall risk in older adults through a systematic review with meta-analysis. Fall risk was assessed through timed up and go, Berg Balance Scale, or one-leg stand tests. Data are presented as mean differences for timed up and go test and standardized mean differences for Berg Balance Scale and one-leg stand tests between treatments with 95% confidence intervals, and calculations were performed using random effects models. Significance was accepted when p < .05. A significant difference was found between dance interventions and the control groups in the general analysis of fall risk assessed by timed up and go (mean differences: -1.446 s; 95% confidence interval [-1.586, -1.306]; p < .001) and Berg Balance Scale and one-leg stand tests (standardized mean differences: 0.737; 95% confidence interval [0.508, 0.966]; p < .001) in favor of the intervention group. Different dance interventions decreased the fall risk in older practitioners.

A randomized sham-controlled trial on the effects of dual-tDCS "during" physical therapy on lower limb performance in sub-acute stroke and a comparison to the previous study using a "before" stimulation protocol

Background

Dual-transcranial direct current stimulation (tDCS) has been used to rebalance the cortical excitability of both hemispheres following unilateral-stroke. Our previous study showed a positive effect from a single-session of dual-tDCS applied before physical therapy (PT) on lower limb performance. However, it is still undetermined if other timings of brain stimulation (i.e., during motor practice) induce better effects. The objective of this study was to examine the effect of a single-session of dual-tDCS “during” PT on lower limb performance in sub-acute stroke and then compare the results with our previous data using a “before” stimulation paradigm.

Method

For the current “during” protocol, 19 participants were participated in a randomized sham-controlled crossover trial. Dual-tDCS over the M1 of both cortices (2 mA) was applied during the first 20 min of PT. The Timed Up and Go and Five-Times-Sit-To-Stand tests were assessed at pre- and post-intervention and 1-week follow-up. Then, data from the current study were compared with those of the previous “before” study performed in a different group of 19 subjects. Both studies were compared by the difference of mean changes from the baseline.

Results

Dual-tDCS “during” PT and the sham group did not significantly improve lower limb performance. By comparing with the previous data, performance in the “before” group was significantly greater than in the “during” and sham groups at post-intervention, while at follow-up the “before” group had better improvement than sham, but not greater than the “during” group.

Conclusion

A single-session of dual-tDCS during PT induced no additional advantage on lower limb performance. The “before” group seemed to induce better acute effects; however, the benefits of the after-effects on motor learning for both stimulation protocols were probably not different.

Effectiveness of Constraint-Induced Movement Therapy (CIMT) on Balance and Functional Mobility in the Stroke Population: A Systematic Review and Meta-Analysis

Constraint-induced movement therapy (CIMT) is one of the most popular treatments for enhancing upper and lower extremity motor activities and participation in patients following a stroke. However, the effect of CIMT on balance is unclear and needs further clarification. The aim of this research was to estimate the effect of CIMT on balance and functional mobility in patients after stroke. After reviewing 161 studies from search engines including Google Scholar, EBSCO, PubMed, PEDro, Science Direct, Scopus, and Web of Science, we included eight randomized controlled trials (RCT) in this study. The methodological quality of the included RCTs was verified using PEDro scoring. This systematic review showed positive effects of CIMT on balance in three studies and similar effects in five studies when compared to the control interventions such as neuro developmental treatment, modified forced-use therapy and conventional physical therapy. Furthermore, a meta-analysis indicated a statistically significant effect size by a standardized mean difference of 0.51 (P = 0.01), showing that the groups who received CIMT had improved more than the control groups. However, the meta-analysis results for functional mobility were statistically insignificant, with an effect size of −4.18 (P = 0.16), indicating that the functional mobility improvements in the investigated groups were not greater than the control group. This study’s findings demonstrated the superior effects of CIMT on balance; however, the effect size analysis of functional mobility was statistically insignificant. These findings indicate that CIMT interventions can improve balance-related motor function better than neuro developmental treatment, modified forced-use therapy and conventional physical therapy in patients after a stroke.

Psychometric Properties of the Trail Walking Test for People With Stroke

Objective

To investigate (i) the inter-rater and test–retest reliability of the trail walking test (TWT) and the minimum detectable change in the TWT completion time; (ii) the correlations between the TWT completion time and stroke-specific impairments; and (iii) the cutoff TWT completion time to distinguish between people with stroke and healthy older adults according to dual-tasking ambulation ability.

Design

Cross-sectional study.

Setting

University-based rehabilitation center.

Participants

In total, 104 people with stroke and 53 healthy older adults.

Main Outcome Measures

The TWT, the Fugl–Meyer Assessment of Lower Extremity (FMA-LE), the ankle muscle strength test, the limit of stability (LOS) test, the Berg Balance Scale (BBS), the Timed Up and Go test (TUG), and the Community Integration Measure (CIM).

Results

The mean TWT completion time in subjects with stroke was 124.906 s. The TWT demonstrated excellent inter-rater reliability [intraclass correlation (ICC) = 0.999] and good test–retest reliability (ICC = 0.876) in people with stroke. The TWT performance demonstrated significant negative correlations with the FMA-LE scores (r = −0.409), LOS movement velocity (affected and unaffected sides; r = −0.320 and −0.388, respectively), and LOS endpoint excursion (affected and unaffected sides; r = −0.357 and −0.394, respectively); a significant positive correlation with the LOS reaction time (affected side; r = 0.256); a moderate negative correlation with the BBS scores (r = −0.72); and an excellent positive correlation with the TUG completion time (r = 0.944). The receiver operating characteristic curve analysis revealed that an optimal cutoff of 69.61 s for the TWT completion time had an outstanding diagnostic power to distinguish between people with stroke and healthy older adults (area under the curve = 0.919) with high sensitivity (88.5%) and specificity (83.0%).

Conclusion

Results of our preliminary study demonstrated that the TWT is a reliable, valid, sensitive, and specific clinical test for evaluating dual-tasking ambulation ability in people with stroke aged 45 years or above and without cognitive impairments. It can differentiate the dual-tasking ambulation ability between people with stroke and healthy older adults.

The effect of motor relearning on balance, mobility and performance of activities of daily living among post-stroke patients: Study protocol for a randomised controlled trial

BACKGROUND

Balance and gait impairments are the most common motor deficits due to stroke, limiting the patients' daily life activities and participation in society. Studies investigating effect of task-specific training using biomechanical balance and gait variables (i.e. kinetic and kinematic parameters) as well as posturography after stroke are scarce.

OBJECTIVES

The primary aim of this study is to assess the efficacy and long-term outcome of task-specific training based on motor relearning program (MRP) on balance, mobility and performance of activities of daily living among post-stroke patients.

METHODS

In this two-armed randomised controlled clinical trial, a total of 66 sub-acute stroke patients who meet the trial criteria will be recruited. The patients will randomly receive task-specific training based on MRP or a conventional physical therapy program (CPT). Twenty-four physiotherapy sessions will be conducted, divided into three training sessions per week, 1 h per session, for 8 weeks, followed by an analysis of changes in patient's balance, gait and performance of activates of daily living at three time periods; baseline, post-intervention and follow-up after 3-months, using clinical outcome measures and instrumental analysis of balance and gait.

DISCUSSION

The results of this study can guide to better understanding and provide an objective clinical basis for the use of task-specific training in stroke rehabilitation. Also, it intends to help bridge the current knowledge gap in rehabilitation and training recommendations to provide a therapeutic plan in post-stroke rehabilitation.
