Using the thermal sense as a model for nociception, the effects of conventional and acupuncture-like transcutaneous nerve stimulation (TNS) were tested on thresholds for warm and cold sensation in 8 healthy subjects. Photic stimulation did not change the thermically neutral zone (the warm-cold difference limen) from that seen under baseline conditions. However, the thermal difference limen usually increased with both types of TNS. The effect was ipsi- as well as contralateral, implying that a central inhibitory mechanism is activated by conventional and acupuncture-like TNS.
以热觉作为痛觉感受的模型,对8名健康受试者进行常规经皮神经电刺激(TNS)和类针刺经皮神经电刺激,测试其对冷热感觉阈值的影响。光刺激并未改变热中性区(冷热辨别阈),与基线条件下所见无异。然而,两种类型的TNS通常都会使冷热辨别阈升高。这种效应在同侧和对侧均有出现,这意味着常规经皮神经电刺激和类针刺经皮神经电刺激激活了一种中枢抑制机制。
