As a stroke survivor and an OT who specialized in stroke rehab, I am not impressed with most motion capture systems for stroke survivors. First, these systems create the impression that you need a computer to see and analyze movement. But analysts who watch ice skaking and diving demonstrate how accurate the human eye is when you know where to look. Slow motion replays have proven that experts can detect if a skater's foot did not land correctly after a quadruple jump or divers bent their hips slightly just before they entered the water. Second, most of these systems focus only on shoulder and elbow movements while the hand maintains a static grasp on a handle. Hello - all the arm does is deliver the hand to the target.
The one system that impresses me is Amadeo. It monitors each individual finger plus the thumb as the hand opens and closes. It provides biofeedback to help clients learn what their muscles are doing before they see visible motion. It can provide EMG stimulation if a client's muscles need assistance. The forearm can be placed in different positions to help the hand adjust to different positions that objects assume in the real world. It can be used in exercise mode or with video games. You can see a demonstration of Amadeo at youtube.com/watch?v=GM9HjI2OIrA. Of course, roll-out of this system is constrained by how many rehab centers can afford it. homeafterstroke.blogspot.com
