A randomized controlled trial compared live interactive videoconference training to pre-recorded video sessions in 94 individuals with chronic low back pain (CLBP) over a 12-week period. Of the participants, 57 (average age 48.4 ± 12.5 years, 36 women) completed the study with comparable attrition rates across groups. Both exercise modalities produced significant and clinically worthwhile (> 20%) reductions in pain intensity compared to a waitlist control, as well as decreases in movement-evoked pain. No differences were observed between live and pre-recorded formats for pain intensity, perceived difficulty, effort, fatigue, satisfaction, or training-related pain.
The therapeutic effects were moderated by sex, with women reporting less pain relief, and mediated by improvements in self-perceived general health, increased physical activity levels, and greater gait speed (4-meter gait task). These findings indicate that remote exercise training—regardless of delivery mode—is an accessible and effective alternative for alleviating CLBP symptoms.
The results support that both live interactive and pre-recorded remote physical exercise training are equally effective interventions for CLBP management, with clinical benefits stemming from enhanced physical activity engagement, improved gait speed, and better self-rated general health.
