简要总结
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.
详细描述
Study Design:
A single-centre, open-label, parallel-group randomised controlled trial conducted at a logistics company in Okinawa, Japan.
Participants:
Inclusion criteria: full-time office workers aged 20 to 65 years, chronic nonspecific low-back pain intensity ≥ 30 mm (100-mm visual analogue scale; VAS).
Exclusion criteria: prior lumbar surgery, ongoing pharmacologic treatment for low-back pain, anticipated changes in job duties during the trial period.

结局指标
主要结局
Low Back Pain Intensity (VAS)
时间窗: Baseline and Week 4
Low back pain intensity assessed using a 100-mm Visual Analogue Scale (0 mm = no pain, 100 mm = worst imaginable pain).
Physical Fatigue During Computer Work (VAS)
时间窗: Baseline and Week 4
Physical fatigue during computer work assessed using a 100-mm Visual Analogue Scale (0 mm = no fatigue, 100 mm = extreme fatigue).
Self-rated Work Performance (SPQ)
时间窗: Baseline and Week 4
Self-rated work performance assessed using the Single-Item Presenteeism Question (0% = no productivity, 100% = full productivity).
