Development and feasibility testing of a video-based exercise program for improving upper limb motor function among stroke survivors in a low-income setting.

The feasibility test had only one group, no control group, and no randomization, so the motor-score improvement cannot be shown to be caused by the intervention. Adherence and compliance relied on self-reported diaries without objective monitoring, so recall and social desirability bias are possible. Participants were selected purposively and many had college-level education and digital literacy, so results may not apply to lower-literacy or underserved communities. Rural scalability may be limited by poor mobile connectivity and unreliable electricity. One participant died from unrelated medical issues and was excluded, leaving 29 analysed. The intervention included several components delivered together, so the contribution of the video, manual, exercises, or constraint-induced movement therapy cannot be separated.

The authors declared no conflict of interest, and the research received no specific grant from any public, commercial, or not-for-profit funding agency.

Do not read the 8.8-point Wolf Motor Function Test gain as proof that the video caused upper-limb recovery. The study had no control group, no randomization, and self-reported adherence, and it combined the video with an instruction manual and five exercises, including constraint-induced movement therapy, so the effect of any single component cannot be separated.
