Background:Recent findings of clinical studies have demonstrated a significant positive relationship between Fugl–Meyer Assessment of upper extremity score and the action research arm test (ARAT) score in people with stroke. Although the motor activity log (MAL) can assess the self-perception of motor performance, which can affect the performance of the upper limb, the relationship between MAL score and ARAT score still remains unclear. The objective of this study is to quantify the independent contribution of MAL score and FMA-hand score on the ARAT score in people with stroke.MethodsThis is a cross-sectional study. There were a total of 87 subjects (50 males, 37 females; mean age = 61.12 ± 6.88 years, post-stroke duration=6.31 ± 2.84 years) included in this study. Self-perceived performance in using the paretic limb was measured by MAL, including subscale of the amount of usage (MAL-AOU) and quality of movement (MAL-QOM). Functional performance of the upper limb was measured by action research arm test (ARAT). Upper limb motor control of the hand was measured by hand section of Fugl–Meyer assessment (FMA-hand).ResultsThe result showed that MAL-QOM (r = 0.648, p < 0.001), MAL-AOU (r = 0.606, p < 0.001), FMA-hand scores (r = 0.663, p < 0.001), and the use of a walking aid (r = −0.422, p < 0.001) were significantly correlated with the ARAT scores. A total 66.9% of the variance in the ARAT scores was predicted by the final regression model including MAL-QOM, MAL-AOU, FMA-hand scores, and walking aid. The FMA-hand score was the best predictor of ARAT scores, which can predict a 36.4% variance of ARAT scores in people with stroke, which controlled the effect of using a walking aid. After controlling for use of a walking aid and FMA-hand scores, the multiple linear regression modeling showed that MAL-QOM and MAL-AOU scores could also independently predict an additional 10.4% of the variance in ARAT scores.ConclusionIn addition to the FMA-hand score, the MAL score was significantly correlated with the ARAT score. Improving self-perceived performance should be one goal of rehabilitation in people with stroke. Further work developing and testing techniques to do so is clearly warranted.

Background. Social support is important for stroke rehabilitation. Conventionally, social support is evaluated from the level of support received. However, the bidirectional support hypothesis postulated that self-perceived social support is optimized if individuals provide and receive social support in a balanced manner. The Brief 2-Way Social Support Scale (Brief 2-Way SSS) is a social support instrument measuring the reciprocity of receiving and giving emotional and instrumental social support. Objective. (1) To translate and culturally adapt the English version of the Brief 2-Way SSS into Chinese (Cantonese) (Brief 2-Way SSS-C), (2) to report the results of validation of the Brief 2-Way SSS-C, and (3) to investigate the level of social support in people with stroke in Hong Kong. Methods. The Brief 2-Way SSS-C was produced following the standard forward-backward translation model. People with stroke ( n = 109 ) and age-matched controls ( n = 53 ) were recruited through a university-affiliated neurorehabilitation laboratory. Results. The Brief 2-Way SSS-C demonstrated excellent content validity, acceptable to good internal consistency (Cronbach’s alpha of 0.74–0.88), and good test-retest reliability (intraclass correlation coefficient of 0.76–0.81). There were no ceiling or floor effects, and the MDC95 across all subscales was 4. The Brief 2-Way SSS-C subscales had significant correlations with various health-related outcome measures. People with stroke had a lower level of social support than the age-matched healthy controls. Conclusions. The Brief 2-Way SSS-C is a culturally relevant, reliable, and valid outcome measure for the level of social support in community-dwelling people with stroke.

Background and Purpose: Recent evidence has shown bilateral transcutaneous electrical nerve stimulation (Bi-TENS) combined with task-oriented training (TOT) to be superior to unilateral transcutaneous electrical nerve stimulation (Uni-TENS)+TOT in improving lower limb motor functioning following stroke. However, no research explored the effect of Bi-TENS+TOT in improving upper limb motor recovery. This study aimed to compare Bi-TENS+TOT with Uni-TENS+TOT, Placebo transcutaneous electrical nerve stimulation (Placebo-TENS)+TOT, and no treatment (Control) groups in upper limb motor recovery. Methods: This is a 4-group parallel design. One hundred and twenty subjects were given either Bi-TENS+TOT, Uni-TENS+TOT, Placebo-TENS+TOT, or Control without treatment in this randomized controlled trial. Twenty 60-minute sessions were administered 3× per week for 7 weeks. The outcome measure was the Fugl-Meyer Assessment of Upper Extremity, which was assessed at baseline, after 10 sessions (mid-intervention) and 20 sessions (post-intervention) of intervention, and at 1- and 3-month follow-up. Results: Patients in the Bi-TENS+TOT group showed greater improvement in the Fugl-Meyer Assessment of Upper Extremity scores than Uni-TENS+TOT (mean difference, 2.13; P =0.004), Placebo-TENS+TOT (mean difference, 2.63; P <0.001), and Control groups (mean difference, 3.11; P <0.001) at post-intervention. Both Bi-TENS+TOT (mean difference, 3.39; P <0.001) and Uni-TENS+TOT (mean difference, 1.26; P =0.018) showed significant within-group improvement in the Fugl-Meyer Assessment of Upper Extremity scores. Patients in the Bi-TENS+TOT group showed earlier within-group improvement in the Fugl-Meyer Assessment of Upper Extremity scores at mid-intervention than Uni-TENS+TOT. These improvements were maintained at the 3-month follow-up assessment. Conclusions: Bi-TENS combined with TOT is an effective therapy for improving upper limb motor recovery following stroke.

The Jacket Test is a reliable and valid measure tool in clinic to evaluate the upper extremity function in people with chronic stroke. Implication for rehabilitation The Jacket Test completion times has excellent intra-rater, inter-rater and test-retest reliabilities in patients with chronic stroke. The Jacket Test completion times significantly correlated with motor functions of the upper limbs. The Jacket Test completion times of 18.33s in affected side and 18.38s for unaffected side (sensitivity 96.7%; specificity 85.7%-96.4%) was found to be the most representative for discriminating chronic stroke survivors and healthy older adults. The Jacket Test is a reliable and valid measuring tool to evaluate the upper extremity function of people with chronic stroke.
