An Alternative Approach to Distinguish Movements of Parkinson Disease Patients

The set of the motion mass parameters, describing the amount and smoothness of movements, is employed as a main tool to demonstrate the differences between the patients with Parkinson disease and the group of healthy individuals, performing the Up-and-Go test. Unlike many existing results in this area, which are based on some features associated to the particular time instance, motion mass parameters are computed for the certain time interval and therefore describe movement in general. The main goal of the present study is to demonstrate that the motion mass parameters associated with the segments of the Up-and-Go test significantly differ between patients with Parkinson disease and healthy individuals.
