Adaptive Physical Activity for Stroke: An Early-Stage Randomized Controlled Trial in the United States.

The trial was too small to test the main between-group question: 76 subjects were randomized and 48 completed, while the authors estimated that 310 subjects would be needed for 80% power. The APA-Stroke group received walking, bar-supported standing exercises, seated upper-limb exercises, homework, instructor encouragement, and peer interaction, while Sittercise received supervised seated exercise with instructor encouragement and peer interaction; this design cannot separate the contribution of any single APA component. Dropout was common and uneven: 58% of APA and 70% of Sittercise participants completed, and higher-functioning Sittercise participants dropped out more often, which changed the baseline comparison between groups. The groups were well matched except for the Short Physical Performance Battery walking subscale at baseline. No post-study follow-up was done to see whether gains persisted. Stroke Impact Scale changes differed by site, with all participants at MedStar National Rehabilitation Hospital improving more than Howard County participants. Recruitment took 52 months, and transportation barriers were prominent at the Washington, DC site.

Do not conclude that the adaptive walking program was better than the seated control. The main between-group comparison was not significant, and the trial was too small to prove superiority. The APA group's improvement occurred in a package of walking, bar-supported standing exercises, seated upper-limb exercises, homework, instructor encouragement, and peer interaction, so no single component can be credited.
