The Evaluation of Ankle Joint Braces Efficiency

Study Overview
=================
Brief Summary
-----------------
The project concerns the evaluation of commercially available ankle joint braces effectiveness used as orthopedic supply after ankle joint ligaments tear injury. Authors hypothesize that the restriction of range of motion may be not sufficient in the early healing process.
