Nonparetic knee extensor strength is the determinant of exercise capacity of community-dwelling stroke survivors.

ABSTRACT: To investigate the relationship among walking speed, exercise capacity, and leg strength in community dwelling stroke subjects and to evaluate which one was the leading determinant factor of them.This is a descriptive, cross-sectional study. Thirty-five chronic stroke patients who were able to walk independently in their community were enrolled. Walking speed was evaluated by using the 12-meter walking test. A maximal exercise test was used to determine the stroke subjects' exercise capacity. Knee extensor strength, measured as isokinetic torque, was assessed by isokinetic dynamometer.The main walking speed of our subjects was 0.52 m/s. Peak oxygen uptake (VO₂ peak) was 1.21 ± 0.43 L/min. Knee extensor strength, no matter whether paretic or nonparetic side, was significantly correlated to 12-meter walking speed and exercise capacity. Linear regression also showed the strength of the affected knee extensor was the determinant of walking speed and that of the nonparetic knee extensor was the determinant of exercise capacity in community dwelling stroke subjects.Walking speed and peak oxygen uptake were markedly decreased after stroke. Knee extensor strength of nonparetic leg was the most important determinant of exercise capacity of the community-dwelling stroke subjects. Knee extensor strengthening should be emphasized to help stroke patient to achieve optimal community living.

Project description:BackgroundStroke survivors constantly feel helpless and unprepared after discharge from hospitals. More flexible and pragmatic support are needed for their optimized recovery. We examined the effects of a virtual multidisciplinary stroke care clinic on survivors' health and self-management outcomes.MethodsA randomized controlled trial was conducted. Survivors were recruited from 10 hospitals and randomized at 1:1 ratio into the intervention or the control groups. Intervention group participants received the Virtual Multidisciplinary Stroke Care Clinic service (monthly online consultations with a nurse, follow-up phone calls, and access to an online platform). Control group participants received the usual care. Outcomes of self-efficacy (stroke self-efficacy questionnaire; primary), self-management behaviors (Stroke Self-Management Behaviors Performance Scale), social participation (reintegration to normal living index), and depression (Geriatric Depression Scale; secondary) were measured at baseline, and 3 and 6 months after commencing the intervention (post-randomization). A generalized estimating equations model was used to compare the differential changes in outcomes at 3 and 6 months with respect to baseline between 2 groups.ResultsBetween July 2019 and June 2022, 335 eligible participants were enrolled in the study. Participants (intervention group; n=166) showed significantly greater improvements in outcomes of self-efficacy (group-by-time interaction regression coefficient, B=4.60 [95% CI, 0.16 to 9.05]), social participation (B=5.07 [95% CI, 0.61 to 9.53]), and depression (B=-2.33 [95% CI, -4.06 to -0.61]), and no significant improvement in performance of self-management behaviors (B=3.45, [95% CI, -0.87 to 7.77]), compared with the control group (n=169) right after the intervention (6 months after its commencement). Hedges' g effect sizes of the intervention on outcomes: 0.19 to 0.36.ConclusionsThe results provide some positive evidence on the usefulness of the Virtual Multidisciplinary Stroke Care Clinic service. The effect sizes are regarded as small to medium, which may not be of clinical relevance. The baseline levels in outcomes were in favor of the control group, the intervention effects might be overestimated. The service must be tested further to determine its effectiveness.RegistrationURL: https://www.chictr.org.cn; Unique identifier: ChiCTR1800016101.
