Objectives. To (1) translate and culturally adapt the English version Community Integration Measure into Chinese (Cantonese), (2) report the results of initial validation of the Chinese (Cantonese) version of CIM (CIM-C) including the content validity, internal consistency, test-retest reliability, and factor structure of CIM-C for use in stroke survivors in a Chinese community setting, and (3) investigate the level of community integration of stroke survivors living in Hong Kong.Design. Cross-sectional study.Setting. University-based rehabilitation centre.Participants. 62 (n=62) subjects with chronic stroke.Methods. The CIM-C was produced after forward-backward translation, expert panel review, and pretesting. 25 (n=25) of the same subjects were reassessed after a 1-week interval.Results. The items of the CIM-C demonstrated high internal consistency with a Cronbach’sαof 0.84. The CIM-C showed good test-retest reliability with an intraclass correlation coefficient (ICC) of 0.84 (95% confidence interval, 0.64–0.93). A 3-factor structure of the CIM-C including “relationship and engagement,” “sense of knowing,” and “independent living,” was consistent with the original theoretical model. Hong Kong stroke survivors revealed a high level of community integration as measured by the CIM-C (mean (SD): 43.48 (5.79)).Conclusions. The CIM-C is a valid and reliable measure for clinical use.

Background: 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 Oxford Participation and Activities Questionnaire was developed for generic use in the assessment of participation and activity levels. However, it is not available in Chinese and has not been tested in the stroke population. The Oxford Participation and Activities Questionnaire was translated into Chinese and culturally adapted. Its psychometric properties were examined in 100 people with stroke. The participation and activity levels of people with stroke and healthy people were also compared. Content validity and internal consistency (Cronbach’s α = 0.86–0.91) were excellent. The test–retest reliability (intraclass correlation coefficient = 0.91–0.94) was also satisfactory. The standard error of the measurement was 4.10–5.31, and the minimal detectable change was 11.37–14.71. Convergent and divergent validity were supported by hypothesis testing. The instrument had a five-factor structure without a ceiling effect. Its routine activity and social engagement scores discriminated people with stroke from healthy people. In conclusion, the Chinese version of the Oxford Participation and Activities Questionnaire is reliable and valid for assessing participation and activity levels in the stroke population.

Yoga is a popular training practice that enhances women’s physical activity level and modifies the major risk factors contributing to noncommunicable diseases. This study aimed to compare general health and cardiovascular health, musculoskeletal health, psychological health, and health-related quality of life between aged women with and without long-term yoga practice. Thirty-two female yoga practitioners (mean age 56 years) with ≥ 2 years experience in regular yoga practice and 32 age-matched women without yoga experience participated in the study. Between-group comparisons was performed to explore the differences in various health outcomes, including body build indices, exercise endurance, blood pressure, and heart rate variability; hamstring flexibility, upper-limb muscle strength, shoulder range of motion, and upper-limb function; and the symptoms of anxiety and depression, sleep quality, and fatigue. Our findings revealed that yoga practitioners demonstrated greater hamstring flexibility, shoulder ROM on the non-dominant side, and hand-grip strength; a higher heart rate variability parameter value (RMSSD); and shorter sleep latency than those who did not practice yoga. In view of the encouraging results of the long-term benefits of yoga practice, it warrants being promoted among aged women to enhance their physical and mental well-being.

The Falls Risk for Older People in the Community assessment (FROP-Com) was originally developed using 13 risk factors to identify the fall risks of community-dwelling older people. To suit the practical use in busy clinical settings, a brief version adopting 3 most fall predictive risk factors from the original FROP-Com, including the number of falls in the past 12 months, assistance required to perform domestic activities of daily living and observation of balance, was developed for screening purpose (FROP-Com screen). The objectives of this study were to investigate the inter-rater and test-retest reliability, concurrent and convergent validity, and minimum detectable change of the FROP-Com screen in community-dwelling people with stroke. Community-dwelling people with stroke (n = 48) were recruited from a local self-help group, and community-dwelling older people (n = 40) were recruited as control subjects. The FROP-Com screen exhibited moderate inter-rater (Intraclass correlation coefficient [ICC]2,1 = 0.79, 95% confidence interval [CI]: 0.65–0.87) and test-retest reliability (ICC3,1 = 0.70, 95% CI: 0.46–0.83) and weak associations with two balance measures, the Berg Balance Scale (BBS) (rho = -0.38, p = 0.008) and the Timed “Up & Go” (TUG) test (rho = 0.35, p = 0.016). The screen also exhibited a moderate association with the Chinese version of the Activities-specific Balance Confidence Scale (ABC-C) (ABC-C; rho = -0.65, p<0.001), a measure of subjective balance confidence. The FROP-Com screen is a reliable clinical tool with convergent validity paralleled with subjective balance confidence measure that can be used in fall risk screening of community-dwelling people with stroke. However, one individual item, the observation of balance, will require additional refinement to improve the potential measurement error.
