Abstract
A system and method are disclosed for measuring range of motion of a body joint formed between a first body portion and a second body portion. The system includes a range of motion sensor comprising a support linkage having a first link joined to a second link for relative movement therebetween. The first link is adapted to be retained for movement with the first body portion and the second link is adapted to be retained for movement with the second body portion. An angular sensing device senses angular displacement of the second link relative to the first link and provides a representative indication thereof. A force sensing device joined to the support linkage senses the applied force to the first body portion and provides a representative indication thereof. Output signals from the angular sensing device and the force sensing device are provided to a signal processor for recording and analysis.
