Background
People use lumbar supports to prevent low back pain. Secondary analyses from primary preventive studies suggest benefit among workers with previous low back pain, but definitive studies on the effectiveness of supports for the secondary prevention of low back pain are lacking.

Objective
To determine the effectiveness of lumbar supports in the secondary prevention of low back pain.

Design
Randomized, controlled trial.

Setting
Home care organization in the Netherlands.

Patients
360 home care workers with self-reported history of low back pain.

Intervention
Short course on healthy working methods, with or without patient-directed use of 1 of 4 types of lumbar support.

Measurements
Primary outcomes were the number of days of low back pain and sick leave over 12 months. Secondary outcomes were the average severity of low back pain and function (Quebec Back Pain Disability scale) in the previous week.

Results
Over 12 months, participants in the lumbar support group reported an average of −52.7 days (CI, −59.6 to −45.1 days) fewer days with low back pain than participants who received only the short course. However, the total sick days in the lumbar support group did not decrease (−5 days [CI, −21.1 to 6.8 days]). Small but statistically significant differences in pain intensity and function favored lumbar support.

Limitations
Study participants were unblinded, and a substantial amount of missing data required imputation. Objective data on sick days due to low back pain were not available.

Conclusion
Adding patient-directed use of lumbar supports to a short course on healthy working methods may reduce the number of days when low back pain occurs, but not overall work absenteeism, among home care workers with previous low back pain. Further study of lumbar supports is warranted.
