Abstract |
In order to screen neurological patients for the presence or absence of functional impairment, we employed a simple loading task using an internal forward model of the motor system based on the computational theory of posture control. In the self-loading task, the patients were required to put an object on their left palm with their right hand while in the non-self-loading task, the examiner put the object on their palm. Since a motor command in a self- task accompanies its efferent copy, subjects with a normal, internal forward model should be able to predict the end result of the motor command; i.e. their hand does not move. However, patients with parietal and cerebellar lesions moved their hands during the self-task, suggesting that they have some functional impairment in the internal forward model of the motor system. We suggest these patients are candidates for rehabilitation of posture control. |
