Background: Low-back pain (LBP) is common among office workers and can reduce productivity and quality of life. Lumbar support belts are commonly used to manage LBP, but their effectiveness specifically for office workers remains uncertain. Aim: This study investigates whether wearing a commercially available lumbar support belt (Guardner Belt) can reduce low-back pain, decrease physical fatigue during computer work, and improve perceived work performance among office workers with chronic low-back pain. Methods: Thirty office workers with chronic nonspecific low-back pain were randomly assigned to either wear the lumbar support belt during work hours for four weeks or continue usual activities without the belt. Participants' pain, fatigue, and work performance were assessed before and after the intervention period.
