Multicomponent telerehabilitation program for veterans with multimorbidity: A randomized controlled feasibility study.

Sample size was 50, and the authors state the study was not powered to detect differences in secondary outcomes, so the null findings on most measures do not rule out a real effect. The inclusion criterion for physical function was lowered mid-study from fewer than 15 repetitions to 10 or fewer on the 30-second sit-to-stand, after 15 veterans had already enrolled, creating a baseline difference between groups on that test. Actigraphy data collection was problematic: only 36 of 50 participants had valid data at both pre- and post-program timepoints, and the authors identified delays in returning the device as a key issue. The MCTR group showed worsening social disengagement while the EDU group improved, which contradicts the program's social support goal and is unexplained. The program had four components (exercise, coaching, social support, technology) delivered together, so the contribution of any single component cannot be separated.

The REDCap infrastructure was supported by NIH/NCRR Colorado CTSI Grant Number UL1 RR025780. No specific conflicts of interest declaration is visible in the provided text.

Do not read the 2-minute step test improvement as proof the program improves physical function. This was a feasibility study with 50 participants, explicitly not powered to detect differences in secondary outcomes, and most other measures showed no significant difference between groups. The four program components were delivered together, so you cannot attribute the finding to the exercise, the coaching, the group sessions, or the technology alone.
