Effects of a lumbar support on spine posture and motion assessed by electrogoniometer and continuous recording.

OBJECTIVE: To determine whether belt wearing causes changes in lumbar posture and motion during standing and work-related activities. DESIGN: The lumbar spine sagittal kinematics of healthy subjects were assessed with an electrogoniometer during a dynamic test and continuous recording with and without a lumbar support. Correlation between data from electrogoniometer and X-ray was established in preliminary experiments.
