TRACKING improvement
FIRST STEP: a UPDRS test, a push test with video, a walking and turning test with video, a talking test with video and possibly a writing test with video, standing from seated on hard back chair video with your arms crossed. These videos are kept on file to be used for comparison with future videos. This is a fairly accurate means of documenting improvements over time as it is actually fairly easy for some people to not realize how much they have improved over time.
