Abstract
The results of the study on conjugate reaction time (RT) of hands (the time of simple mental reaction) of 16 patients with Parkinsonism, cerebral palsy, and spastic torticollis before and after surgery are presented. Conjugation of the left hand and right hand RTs to sound and light modality signals with a warning signal has been analyzed to detect the morphological structures that influence the conjugate reaction. In some of the patients, no disturbance of RT conjugation was shown; in other patients, the coefficient of correlation used for assessment of the left and right hand RT conjugation significantly changed. The coefficient of correlation between the left hand and right hand RTs decreased in response either to the sound signal or simultaneously to the sound and light signals. Disturbances of the conjugate hand reaction were observed in the case of ventral-lateral thalamotomy, subthalamotomy, and pallidotomy.
