ROLE OF PREOPERATIVE AND POSTOPERATIVE SENSORIMOTOR TRAINING ON RESTORATION OF THE EQUILIBRIUM BEHAVIOR IN ADULT MICE FOLLOWING CEREBELLECTOMY

The equilibrium behavior of cerebellectomized C57/BL6 adult mice was studied on a rota rod rotating at 20 revolutions per minute and the influence of preoperative or/and postoperative training on restoration of equilibrium capabilities investigated. The duration of the preoperative training was either short (1 day) or long (7 days). The postoperative training began either the day after cerebellectomy or was delayed by 7 days. The results demonstrate that postoperative training was efficient in restoring the equilibrium behavior in all cases, except for the animals which were trained for a long period (7 days) before the lesion. Preoperative training was also efficient providing it was long enough (7 days), except for the animals which postoperative training began the day after cerebellectomy. It can be stated that both preoperative and postoperative trainings influence the restoration of the equilibrium following a cerebellectomy and that, in some instances, preoperative training can be as efficient as postoperative.
