Vibrotactile thresholds for a 20Hz and a 150Hz stimulus were determined during high-frequency (100Hz) transcutaneous electrical nerve stimulation (TENS) of 13-minutes duration. TENS was applied either at a site proximal or distal to the probe of the vibrator at an intensity which was strong enough to elicit muscle activity. TENS applied at a distal site had no marked effect on vibrotactile thresholds either for a 20Hz or 150Hz stimulus. However, TENS applied at a proximal site caused a marked threshold elevation for both frequencies studied. Present results suggest that vibrotactile threshold elevation produced by high-frequency TENS is due to peripheral electrogenic blockade, presumably an antidromic invasion of vibration receptors.
在持续13分钟的高频（100Hz）经皮电神经刺激（TENS）过程中，测定了20Hz和150Hz刺激的振动触觉阈值。TENS以足以引发肌肉活动的强度施加于振动器探头近端或远端的部位。在远端部位施加TENS对20Hz或150Hz刺激的振动触觉阈值均无明显影响。然而，在近端部位施加TENS会导致所研究的两个频率的阈值显著升高。目前的结果表明，高频TENS引起的振动触觉阈值升高是由于外周电源性阻断，推测是振动感受器的逆向冲动入侵所致。
