The effects of continuous segmental vibration on the biceps femoris (BF) nociceptive flexor reflexes elicited by painful electrical stimulation of the sural nerve at the ankle were investigated in 25 normal subjects. During vibration of 100 Hz frequency, applied either on ipsilateral or contralateral foot skin, the nociceptive BF flexor reflexes increased in amplitude. Marked facilitation was prolonged even 20 minutes after vibration ceased. Pain sensation described by subjects did not change significantly except that radiation of pain was reduced in some cases. The results could not be explained by current views of reflex sensitisation, dishabituation, or the gate control theory.
在25名正常受试者中，研究了连续节段性振动对踝关节处腓肠神经疼痛性电刺激所引发的股二头肌（BF）伤害性屈肌反射的影响。在同侧或对侧足部皮肤施加100Hz频率的振动时，伤害性BF屈肌反射的幅度增加。即使在振动停止20分钟后，明显的易化作用仍持续存在。除了在某些情况下疼痛的放射范围减小外，受试者描述的疼痛感觉没有明显变化。目前关于反射致敏、去习惯化或闸门控制理论的观点无法解释这些结果。
