- Abstract
- The purpose of this study is to investigate the angular rate during motor examination of Parkinson's disease patients, as a quantitative measure of the severity. 14 Parkinson's disease patients, 36 healthy elderly subjects and 13 healthy young subjects participated in the experiments. Three different movements selected from the motor examination category of UPDRS i.e. Finger Taps, Rapid Alternating Movements of Hands and Leg Agility test were performed. Frequency and peak angular velocity of swing were derived from the experimental angular rate. Both the frequency and peak velocity showed negative correlation with the clinical score. This suggests that the angular rate can be used for a quantitative measurement of severity in Motor Examination.
