An evaluation method on movement function of human upper limb

Objective: To study the pointing movement characteristics of healthy human's upper limb when pointing the different targets on the front board, and to discuss the new method of evaluating upper limb movement function for movement disorder patients to provide the references for rehabilitation training and detection of movement disorder patients. Method: Twenty-one male healthy volunteers were chosen. The pointing experiment of human upper limb was designed and carried out. By the statistic analysis of experimental data, the characteristics of pointing movement time for different targets were discussed to use as the references for movement function evaluation on movement disorder patients. Result: The experimental data indicated the forefinger-tip's motion durations were obvious different, and showed possessing very strong regularity. Conclusion: Contrast with the upper limb pointing characteristics of healthy human, the forefinger-tip's motion duration can be used as movement function index on evaluating the movement function of movement disorder patients. The new method is easy and simple to implement.
