Evaluation eines feedbackbasierten trainings zerebraler handfunktionsstörungen mittels kinematischer bewegungsanalyse

Purpose: To evaluate whether a feedback-based training of repetitive joint movements can reduce hand function deficits following brain damage. To analyse whether three-dimensional motion recording is a suitable method for the evaluation of the training. Material and method: Eight patients practised pronation and supination movements or wrist movements using a commercially available device providing video-game-like tasks during ten sessions. The effects of the training and the transfer was analysed in normalized movement tasks using three-dimensional movement analysis. Results: All patients improved in the training tasks. In addition, kinematic analysis manifested a moderate improvement during independent movements of the joint that was trained. No further transfer was obvious. Conclusion: In conjunction with occupational therapy and physiotherapy, a feedback-based repetitive training can reduce motor deficits and can take advantage of the patient's motivation and temporal resources. However, further controlled modification of the training seems desirable to increase efficiency and transfer. Kinematic analysis can support objective and precise evaluation of the training and its modifications.
