Abstract
The effect of physical exercise on compensation forlocomotor asymmetry after unilateral labyrinthcctomy was studied in squirrel monkeys. Five monkeys were assigned to the motor-driven rotating cage exercise. and another five. non-exercise control. Daily exercise (cumulative time of 2 1/2 hours) was given for tht-ee meeks pre-operatively and continuously (daily) post-operaitively.
The average number of calendar days to attain the locomotor balance compensation was 20 days in the exel-cise group, and 35 days in the non-exercise control group. Statictical analysis showed the former compensated (according to the presiously established criterion) significantly faster than the latter (p<0.05). Furthermore. faster reduction of gait deviation was foand in the exercise group. Therefore. when physical exercise was given extensively and continuously. and locomotor balance function was measured by the squirrel monkey platform runuap test (Igarashi. 1974). physical exercise application enhanced the locomotor equilibrium compensation.
