  Purpose
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.

Condition Intervention
Back Pain Low Back Pain Procedure: Sagital xrays

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective

Groups/Cohorts Assigned Interventions
Chronic back pain
This group of patients has had chronic back pain for longer than 3 months.
Procedure: Sagital xrays
5 xrays will be taken: (1) Upright standing position; (2) Upright, straight chair position; (3) Slouching, straight chair position; (4) Upright, ergonomic chair position; (5) Slouching, ergonomic chair position.
Non chronic back pain
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.
Procedure: Sagital xrays
5 xrays will be taken: (1) Upright standing position; (2) Upright, straight chair position; (3) Slouching, straight chair position; (4) Upright, ergonomic chair position; (5) Slouching, ergonomic chair position.
