Locomotion and motion sickness during reversed vision were studied in ten normal subjects and a patient with bilateral labyrinthine loss. Whereas horizontal reversal produced moderate to severe gait disturbances as well as motion sickness in all normal subjects, vertical reversal failed to induce such symptoms. The patient, being free of motion sickness during both reversals, could not walk straight during horizontal reversal. The difference in the strength of sensory mismatch between both directions seemed to result from a difference in the role of vision for spatial orientation which is produced by the proprioceptive as well as otolithic inputs of gravity.
对10名正常受试者和1名双侧迷路丧失患者在视觉颠倒时的运动和晕动病情况进行了研究。水平颠倒会在所有正常受试者中产生中度至重度的步态障碍以及晕动病,而垂直颠倒则不会引发此类症状。该患者在两次颠倒过程中均未出现晕动病,但在水平颠倒时无法直走。两个方向上感觉不匹配强度的差异似乎源于视觉在空间定向中所起作用的不同,而这种不同是由重力的本体感受以及耳石输入所产生的。
