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

Completed

• Conditions: Back Pain; Low Back Pain
• Interventions: Procedure: Sagital xrays

• 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.

Arm && Interventions

Group	Intervention	Description
Chronic back pain	Sagital xrays	This group of patients has had chronic back pain for longer than 3 months.
Non chronic back pain	Sagital xrays	This group of patients is hospitalized for cardio physical therapy, and has no lumbar-pelvic complications. Patients are selected from the hospitalized population according to age, sex, and BMI in order to match chronic back pain patients.
