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

Purpose To assess the effects of a group exercise intervention conducted by real-time videoconference on the low back pain of eldercare workers. Methods We randomly assigned 130 eldercare workers to an experimental group (EG: n = 65) or control group (CG: n = 65). Participants from both groups took part in routine prevention programs carried out in their workplace, and participants from the EG received an additional 12-week resistance-exercise intervention supervised by real-time videoconference. Assessments were conducted before and after the intervention, and the primary outcome was average low back pain intensity during the last 7 days, measured by the 0–10 numerical rating scale. Secondary outcomes included additional measures of low back, neck, shoulder and hand/wrist pain, as well as psycho-affective parameters, medication consumption and muscle performance. Both intention-to-treat and per-protocol analyses were applied with a group-by-time ANCOVA including baseline measurements as covariates. Results 125 participants completed post-intervention assessments (EG: n = 63, CG: n = 62). The intention-to-treat analysis showed an effect favouring the EG on average low back pain intensity ( p = 0.034). Improvements in additional low back and hand/wrist pain outcomes were also observed, as well as on upper limb muscle performance ( p < 0.05). The per-protocol analysis demonstrated additional benefits in depression, quality of life, hypnotic/anxiolytic medication consumption and lower limb and trunk muscle performance in participants with ≥ 50% adherence ( p < 0.05). Conclusions The intervention was effective for reducing the low back and hand/wrist pain of eldercare workers and increasing upper limb muscle performance. The per-protocol analysis showed additional benefits in psycho-affective parameters, medication consumption and muscle performance. Trial registration: ClinicalTrials.gov, NCT05050526.
