Preliminary Study of the Sagittal Alignment of the Lumbo-pelvic Complex in a Sitting Position

Completed

• Conditions: Back Pain; Low Back Pain

• Registration Number: NCT01323127
• Lead Sponsor: Centre Hospitalier Universitaire de Nīmes

Brief Summary

The main objective of this study is to investigate the influence of seat type (straight chair versus "ergonomic" chair) on the sagittal alignment of the lumbo-pelvic complex in two different postures compared to standing for each individual in both a chronic-back-pain and a non-chronic-back-pain population.
