Veterans with spinal cord injury, amputation, or who for other reasons use a manual wheelchair are likely to experience chronic shoulder pain and loss of independence. Biomechanical analysis of wheelchair propulsion can determine the condi- tions likely to result in upper-limb damage and guide wheelchair design, propulsion technique, and recommendations for exercises to strengthen mus- culature around the shoulder joint. We have devel- oped a method for identifying the onset of fatigue in shoulder muscles during wheelchair propulsion. This method helps us identify ways to reduce mus- cle fatigue and overexertion and, therefore, reduce the conditions thought to contribute to degenerative changes in the shoulders of long-term wheelchair users.
