Spontaneous nystagmus and locomotor equilibrium function were repeatedly tested before and after unilateral labyrinthectomy in 12 squirrel monkeys in order to study the effect of physical exercise on the vestibulo-oculomotor and vestibulo-locomotor compensation. Post-operatively, 6 of the monkeys received forced physical exercise in the rotating cage, while the other 6 did not. The provocation of post-operative spontaneous nystagmus was less in the exercise group. The statistical studies showed a certain contribution of physical exercise toward the oculomotor balance compensation and maintenance, probably at the level of the brain stem. Statistical comparison of the locomotor equilibrium performance did not depict a significant difference between the exercise and non-exercise groups; however, there was a possibility that the present testing maneuver which involves physically advanced tasks might have concealed the effect of the physical exercise.
