Videoconference-Supervised Group Exercise Reduces Low Back Pain in Eldercare Workers: Results from the ReViEEW Randomised Controlled Trial.

Only 130 of 436 eligible workers were enrolled, a 30% participation rate, and the exercise sessions were outside working hours, which may have selected more motivated workers. Participants and the instructor were not blinded, which can bias subjective pain reporting. Mean adherence was 67%, and the per-protocol analysis excluded participants with less than 50% adherence, so its additional benefits are not randomised evidence. The trial was powered for the primary low back pain outcome, but secondary outcomes may not have had enough power for reliable conclusions. The sample was almost entirely women and only included eldercare workers, so results may not apply to male workers or other occupations. The subgroup without baseline low back pain was small, so the study cannot show whether the exercise prevents new low back pain. The single-item sleep quality scale had not been cross-culturally validated in Spanish. The model requires access to internet and videoconference technology, which may not be available in all settings.

Do not conclude that videoconference exercise alone caused the improvement. The experimental group received the videoconference sessions in addition to routine workplace prevention programs, while the control group also received those routine programs.
