What this trial studies

This study recruits overweight or obese individuals aged 18 to 65 who suffer from chronic nonspecific low back pain. Participants will be randomly assigned to one of two groups for a 10-week intervention, combining online education and face-to-face sessions with a physical therapist. The experimental group will receive a behavioral weight reduction program alongside pain neuroscience education and cognition-targeted exercise therapy, while the control group will only receive pain education and exercise therapy. The primary outcome measured will be pain intensity, with secondary outcomes including body composition and physical activity levels.

Why it matters

Potential benefit: If successful, this program could significantly reduce pain and improve quality of life for patients with chronic low back pain who are overweight or obese.

How similar studies have gone: Other studies have shown promising results with similar approaches combining weight management and pain education, suggesting potential for success in this trial.
