Robot-Assisted Therapy Combined with Trunk Restraint in Acute Stroke Patients: A Randomized Controlled Study

BACKGROUND

Reducing the compensatory mechanism by restraining unnecessary trunk movements may help enhance the effectiveness of robot-assisted therapy.

OBJECTIVE

This study aimed to investigate the effects of robot-assisted therapy in combination with trunk restraint on upper extremity function and on daily activities in patients with acute stroke (≤ 30days of onset).

METHODS

Thirty-six acute stroke patients were randomly assigned to an experimental (n=18) or control (n=18) group. The experimental group performed robot-assisted therapy combined with trunk restraint, while the control group performed only robot-assisted therapy. Both groups were treated for 30 min, 5 days a week, for a total of 3 weeks. The outcome measures included the Fugl-Meyer assessment upper extremity, wolf motor function test, motor activity log, upper extremity muscle strength, and modified Barthel index.

RESULTS

After the intervention, both groups showed significant improvements in Fugl-Meyer assessment upper extremity, wolf motor function test, motor activity log, elbow extensor muscle strength, and modified Barthel index (p < 0.05). Post-intervention, the experimental group exhibited greater changes in the Fugl-Meyer assessment upper extremity, motor activity log, and elbow extensor muscle strength (p < 0.05).

CONCLUSION

Our study suggests that robot-assisted therapy in combination with trunk restraint is more effective for improving upper extremity function than only robot-assisted therapy in acute stroke patients.

Prevalence and predictors of return to work among stroke survivors in Jordan

BACKGROUND

Returning to work (RTW) is an essential goal for many stroke survivors. Currently, the prevalence of RTW post stroke in developing countries such as Jordan is unknown. Additionally, more research is required to identify factors that contribute to RTW post stroke.

OBJECTIVES

This study aims to (1) determine the prevalence of RTW among stroke survivors in Jordan, and (2) determine the predictors of RTW from a holistic perspective using the Occupational Therapy Practice Framework (OTPF) 3rd edition.

METHODS

Recruitment was carried out from different Jordanian hospitals and rehabilitation centers. A complete battery of outcome measures was used to reflect OTPF domains. These included outcome measures of occupations, client factors, performance skills, and context and environment. Logistic regression was used to determine factors that predicted RTW.

RESULTS

69 participants were enrolled; 45 Males, 24 females; mean age±SD, 52.2±11.07 years. Only 29% succeeded in RTW during the first year after stroke onset. The highest percentage of RTW was among craft workers (40% ), and those who were self-employed (60% ). Of those who resumed work, 35% returned to their previous work, while 65% needed to make work modifications, or change positions or jobs. Factors that predicted higher rates of RTW were walking speed (Odds ratio (OR)=0.004, 95% confidence interval (CI)=0.00-0.55, P < 0.02), as well as absence of environmental restrictions (OR = 21.16, 95% CI = 1.91-233.5, P < 0.013).

CONCLUSIONS

The alarming low prevalence of RTW among stroke survivors in Jordan emphasizes the essential need to develop vocational rehabilitation programs. Clinicians should pay attention to enhancing walking abilities and reducing environmental restrictions post stroke, in order to improve the occurrence of RTW.

Machine-Learning-Based Rehabilitation Prognosis Prediction in Patients with Ischemic Stroke Using Brainstem Auditory Evoked Potential

To evaluate the feasibility of brainstem auditory evoked potential (BAEP) for rehabilitation prognosis prediction in patients with ischemic stroke, 181 patients were tested using the Korean version of the modified Barthel index (K-MBI) at admission (basal K-MBI) and discharge (follow-up K-MBI). The BAEP measurements were performed within two weeks of admission on average. The criterion between favorable and unfavorable outcomes was defined as a K-MBI score of 75 at discharge, which was the boundary between moderate and mild dependence in daily living activities. The changes in the K-MBI scores (discharge-admission) were analyzed by nonlinear regression models, including the artificial neural network (ANN) and support vector machine (SVM), with the basal K-MBI score, age, and interpeak latencies (IPLs) of the BAEP (waves I, I-III, and III-V). When including the BAEP features, the correlations of the ANN and SVM regression models increased to 0.70 and 0.64, respectively. In the outcome prediction, the ANN model with the basal K-MBI score, age, and BAEP IPLs exhibited a sensitivity of 92% and specificity of 90%. Our results suggest that the BAEP IPLs used with the basal K-MBI score and age can play an adjunctive role in the prediction of patient rehabilitation prognoses.

[Measurement of dependence based on the care time and the dependency assessment scale]

AIMS

To assign care time to the activities collected in the Dependency Assessment Scale (BVD) and to analyse the relationship between care time and the score received on the BVD.

METHODS

A cross-sectional observational study of 148 dependent persons was carried out. Socioeconomic and clinical data, the BVD, the 6-dimensional dependency indicator (DEP-6D), as well as data from a diary with the time of care received, were collected. The median time needed to carry out the activities included in the BVD was estimated from the diary. Following the BVD methodology, those who had their mental functions affected were separated. Each person was assigned two scores, one based on BVD and the other based on the time that the caregivers spent to care for them. The correlation between the two was estimated, and a regression was performed to identify the main explanatory factors for the disparity between the two indicators.

RESULTS

BVD and hours of care show a moderate positive correlation. The mental impairment of the dependent person increased the time of care in most activities. The regression analysis suggests that while mental impairment is the main explanatory factor of obtaining a higher assessment with care time than with BVD, being bedridden is the main predictor of having a higher sore with the BVD.

CONCLUSIONS

The construct that underlies BVD is moderately related to care time. Future research must contrast the robustness of these results and address whether the normative criteria that underlie the BVD is aligned with the weights that characterise it.

Effects of modified constraint-induced movement therapy with trunk restraint in early stroke patients: A single-blinded, randomized, controlled, pilot trial

BACKGROUND

Reducing compensatory strategies during repetitive upper-limb training may be helpful in relearning motor skills.

OBJECTIVE

To explore the effects of modified constraint-induced movement therapy (mCIMT), additionally modified by adding trunk restraint (TR), on upper-limb function and activities of daily living (ADLs) in early post-stroke patients.

METHODS

Twenty-four participants with early stroke were randomly assigned to mCIMT combined with TR (mCIMT + TR) or mCIMT alone. Each group underwent twenty sessions (1 h/d, 5 d/wk for 4 weeks). Patients were assessed with the action research arm test (ARAT), the Fugl-Meyer Assessment-Upper extremity (FMA-UE), the Modified Barthel index (MBI), the Maximal elbow extension angle during reaching (MEEAR), and Motor Activity Logs (MAL-AOU and MAL-QOM).

RESULTS

The mCIMT + TR group exhibited greater improvement in the ARAT, FMA-UE, MBI, MEEAR, and MAL-AOU, and MAL-QOM than the mCIMT group. Statistical analyses showed significant differences in ARAT (P = 0.003), FMA-UE (P = 0.042), MBI (P = 0.001), MEEAR (P = 0.002), and MAL-AOU (P = 0.005) between the groups.

CONCLUSION

Modified CIMT combined with TR may be more effective than mCIMT alone in improving upper-limb function and ADLs in patients with early stroke.

Effect of combination of transcranial direct current stimulation and feedback training on visuospatial neglect in patients with subacute stroke: a pilot randomized controlled trial

[Purpose] To investigate the effects of a combination of transcranial direct current stimulation (tDCS) and feedback training (FT) on subacute stroke patients with unilateral visuospatial neglect. [Subjects] The subjects were randomly assigned to a tDCS + FT group (n=6) and a FT group (n=6). [Methods] Patients in the tDCS + FT group received tDCS for 20 minutes and then received FT for 30 minutes a day, 5 days a week for 3 weeks. The control group received FT for 30 minutes a day, 5 days a week for 3 weeks. [Results] After the intervention, both groups showed significant improvements in the Motor-Free Visual Perception Test (MVPT), line bisection test (LBT), and modified Barthel index (MBI) over the baseline results. The comparison of the two groups after the intervention revealed that the rDCS + FT group showed more significant improvements in MVPT, LBT, and MBI. [Conclusion] The results of this study suggest that tDCS combined with FT has a positive effect on unilateral visuospatial neglect in patients with subacute stroke.

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

BACKGROUND

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

Effects of body awareness training on mild visuospatial neglect in patients with acute stroke: a pilot randomized controlled trial

[Purpose] This study aimed to investigate the effects of body awareness training (BAT) on mild visuospatial neglect in patients following acute stroke. [Subjects] The subjects were 12 stroke patients randomly assigned to either the experimental group (n₁=6) or control group (n₂=6). [Methods] The experimental group underwent BAT for 15 minutes and then task-oriented training for 30 minutes a day, five times a week for three weeks. The control group underwent task-oriented training for 30 minutes a day, five times a week for three weeks. Assessments were made using the Motor-free Visual Perception Test (MVPT), Line Bisection Test (LBT), and modified Barthel index (MBI). [Results] Following the interventions, the experimental group showed a significant change in MVPT, LBT, and MBI scores. [Conclusion] The results of this study suggest the feasibility and suitability of BAT with task-oriented training for mild visuospatial neglect in patients with acute stroke.

The effects of modified constraint-induced movement therapy combined with trunk restraint in subacute stroke: a double-blinded randomized controlled trial

OBJECTIVE

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

DESIGN

Double-blind, randomized controlled trial.

SETTING

Rehabilitation clinic.

PARTICIPANTS

Eighteen subacute stroke patients with moderate motor impairment.

INTERVENTIONS

The patients were treated with either mCIMT combined with trunk restraint or mCIMT for 5 days per week for 4 weeks. The mCIMT combined with trunk restraint group participated in structured intervention sessions for use of the more affected upper-extremity in task-oriented activities with trunk restraint for 1 hour per day, and with the less affected upper-extremity restrained for 5 hours per day weeks. The mCIMT group followed the same protocol without trunk restraint.

MAIN OUTCOME MEASURES

The outcome measures included the action research arm test (ARAT), the Fugl-Meyer assessment (FMA), the modified Barthel index (MBI), the motor activity log (MAL) and the maximal elbow extension angle during reaching (MEEAR) were completed at baseline and post intervention.

RESULTS

The mCIMT combined with trunk restraint group exhibited more improved in the ARAT, FMA, MBI, MAL and MEEAR compared with the mCIMT group. Statistical analyses showed significantly different in ARAT (P = 0.046), FMA (P = 0.008), MBI (P = 0.001), MAL-AOU (P = 0.024), MAL-QOM (P = 0.010) and MEEAR (P = 0.001) between groups.

CONCLUSIONS

These results suggest that mCIMT combined with trunk restraint is more helpful to improve upper-extremity function than mCIMT only in subacute stroke patients with moderate motor impairment.

Allocation and preference of patients for domiciliary or institutional rehabilitation after a stroke

On discharge from an acute-care hospital after a stroke, 191 patients were told that they needed rehabilitation and were offered the option of receiving care in an institution or in their homes. One hundred and one (52.4%) patients chose an institution and 91 (47.6%) preferred rehabilitation in their own home. A higher number of women than men chose to be rehabilitated at home. Multivariate logistic regression showed that odds for being included in the home rehabilitation group were higher for women and for those who had a stroke in the past. Odds for being included in the institutional rehabilitation group were individuals with diabetes and difficulty in ambulating and those who had a longer stay in the acute-care hospital. Findings of the study suggest that in Israel there is a sub-population of acute stroke survivors who may be appropriate for rehabilitation at home and accept the option when they are offered it.
