OBJECTIVES: To evaluate the effect of lumbopelvic belts on the thickness of
lateral abdominal muscles and the cross-sectional area (CSA) of lumbar multifidus
(LM) muscles. DESIGN: A single-blinded randomized controlled trial. SETTING: An
academic and tertiary care referral spine and sports medicine center.
PARTICIPANTS: Sixty healthy volunteers with no history of low back pain in the
previous year. METHODS: The subjects were allocated into belt and control groups.
Lumbar belts were given to the subjects in the belt group, and they were asked to
use the belts during the study period except during sleeping hours. The subjects
were assessed at baseline and at 4 and 8 weeks. MAIN OUTCOME MEASURES: The
thickness of lateral abdominal muscles and the CSA of the LM muscles were
measured by ultrasound with the patient in the hook-lying position on an
examination table. RESULTS: The thickness of lateral abdominal muscles and the
CSA of LM muscles on both sides decreased significantly among healthy subjects in
the belt group after 8 weeks. CONCLUSION:
The results of this study show that
lumbopelvic belts might influence the ultrasonographic measurements of lateral
abdominal and LM muscles and thereby spine stability.
