The purpose of the present study was to establish the use of the power flow analysis and the subsequent phase breakdown of the movement pattern as an objective and reliable tool to document in detail movement disabilities observed in Parkinson's disease. Movement was reflected in a series of functional phases responsible for detailed muscle function around the joint as the result of the kinematic output. / The results revealed the importance of the power flow analysis as a sensitive tool for describing coordination disabilities. Similar muscle phenomena were reflected through the functional movement phases of both ability groups. However, the variability in the number of phases increased as a function of the task complexity. The statistical comparison of selected kinematic and dynamic parameters revealed significantly higher peaks for the able-bodied movement profiles. The analysis also demonstrated that the movement deficiencies observed in Parkinson's Disease cannot simply be attributed to the pure force production by the joint musculature. It seems that there is also a problem in managing and organizing the active and passive forces acting at the joint. (Abstract shortened by UMI.)
