The Effect of a New Biomechanical Device

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to examine (retrospectively) the effect of a new biomechanical device on gait patterns of patients suffering from musculoskeletal disorders. The analysis is conducted on an existing database of the therapy center.

Detailed Description
-----------------
Patients treated in the therapy center undergo a computerized gait test and complete several pain and function questionnaires at fixed time point. We examined the effect of the treatment on the level of pain, function and quality of life as well as on the gait patterns of these patients. Measurements were taken at baseline, after 3 months, and after 6 months.

Conditions
-----------------
Osteoarthritis, Joint Replacement, Fractures

Intervention / Treatment
-----------------
* Device: APOS biomechanical gait system
