Motion Analysis Detects Joint Degeneration

If joints do no longer work as usual, humans tend to compensate this by unconsciously adapting their motions. In the case of knee arthrosis, or excessive joint wear, they shift the weight to the healthy leg. This relieves the worn knee joint, but also delays the pain that would indicate the start of...
