Back Pain, Low Back Pain
Conditions
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.
Interventions
PROCEDURESagital 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.
