经皮电刺激镇痛疗法(Transcutaneous Electrical Stimulation简称TES),是通过皮肤电极,将特定的低频脉冲输入人体以治疗疼痛。此疗法目前在美国应用较广泛。近年来在国内也开始应用。本文应用低频方波经皮电刺激作用于健康成年人的脊髓部及双前臂屈指肌,测定作用前后的痛阈及耐痛阈值的变化。以观察低频方波对正常人痛阈 Transcutaneous electrical stimulation (Transcutaneous Electrical Stimulation referred to as TES) is through the skin electrode, the specific low-frequency pulse input to the body to treat pain. This therapy is currently more widely used in the United States. In recent years in China also began to apply. In this paper, low frequency square wave percutaneous electrical stimulation in healthy adult spinal cord and dorsal forearm flexor, measured before and after the pain threshold and pain threshold changes. To observe the low frequency square wave of normal pain threshold
