大于感觉阈值的电触觉（皮肤电）刺激引起感觉适应，从而暂时提高感觉阈值并降低刺激的感知强度。中等强度暴露于条件刺激15分钟后（开10秒，关10秒），根据条件刺激爆发结构中的电流、频率和脉冲数量，受试者的感觉阈值升高60-270%。这些参数中的任何一个增加都会增加感觉阈值的升高。适应和恢复各在大约15分钟内完成。
Electrotactile (electrocutaneous) stimulation at currents greater than sensation threshold causes sensory adaptation, which temporarily raises the sensation threshold and reduces the perceived magnitude of stimulation. After 15 min of moderately intense exposure to a conditioning stimulus (10 s on, 10 s off), the sensation threshold elevation for se, en observers was 60-270%, depending on the current, frequency, and number of pulses in the burst structure of the conditioning stimulus. Increases in any of these parameters increased the sensation threshold elevation. Adaptation and recovery were each complete in approximately 15 min.
