The significance to human postural control of pressor information from the feet was investigated during vestibular disturbance in seven normal subjects who were exposed to bipolar biaural galvanic stimulation of the vestibular nerves before and after their feet were anaesthetized with hypothermia. The increase in body sway in the lateral plane induced by the galvanic stimulus was enhanced when the feet were anaesthetized, and adaptation of postural control to the galvanic stimulus was delayed. It is concluded that pressor information from the feet contributes significantly to postural control in humans and is important in compensating for vestibular disturbance.
在七名正常受试者中，研究了足部压力信息对人体姿势控制的意义。这些受试者在足部经低温麻醉前后，接受了前庭神经的双极双耳电刺激，以模拟前庭干扰。当足部麻醉后，电刺激引起的身体在侧平面的摆动增加，并且姿势控制对电刺激的适应延迟。结论是，来自足部的压力信息对人类的姿势控制有显著贡献，并且在补偿前庭干扰方面很重要。
