Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Chronic back pain

This group of patients has had chronic back pain for longer than 3 months.

Sagital xrays

Intervention Type PROCEDURE

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.

Sagital xrays

Intervention Type PROCEDURE

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.
