使用阻尼摆动旋转表，它提供了一个振荡的15.5秒，旋转性眼球震颤，进行了评价，在6只松鼠猴进行了单侧椎板切除术和5个进行了单侧外半规管阻滞，术前和术后。在单侧前庭切除术后和单侧外半规管阻滞后，眼球震颤慢相眼速的双向总和显示出类似的减少，约为术前状态下获得的值的60%。在本实验条件下，单侧外半规管阻滞后，向壶腹刺激引起的慢相眼速和眼震搏动数均大于离壶腹刺激。单侧外半规管阻滞组和术前对照组慢相眼速与搏动数的关系具有相似的趋势，而单侧外半规管阻滞组慢相眼速与搏动数的关系则不同。
Using a damped pendular rotation table, which provided an oscillation of 15.5 sec, per-rotatory nystagmus, was evaluated in six squirrel monkeys that underwent unilateral labyrinthectomy and five that underwent unilateral lateral semicircular canal block, both pre- and postoperatively. The bidirectional summation of the nystagmic slow-phase eye speed after unilateral labyrinthectomy and after unilateral lateral semicircular canal block showed similar reduction to about 60 per cent of the values obtained in the pre-operative status. Under the present test situation, both slow-phase eye speed and number of nystagmic beats in the monkeys after unilateral lateral semicircular canal block were larger by the ampullopetal stimulation than those evoked by ampullofugal stimulation. The relation between slow-phase eye speed and number of beats showed similar tendency when we compared pre-operative controls and the group after unilateral lateral semicircular canal block, but the monkeys after unilateral labyrinthectomy depicted different tendencies.
