将针插入身体的特定部位显示出提供止痛和治疗效果。在这项研究中，我们测试了高强度红外激光对针刺样刺激的镇痛作用。将12只体重为230 - 250 g的成年Sprague-Dawley大鼠随机分配至激光、针刺或束缚组。刺激经太溪穴10 min。对于激光刺激，使用脉冲Er：YAG系统。调整激光设置，使皮肤温度集中升高至约45°C。用甩尾法评价其镇痛作用。针刺和激光刺激均显著延长甩尾潜伏期。针刺治疗后即刻达到峰值效应，而激光刺激治疗后即刻和45 min均有效。高强度激光刺激可以替代或结合传统针灸用于缓解疼痛。
The insertion of needles into specific parts of the body was shown to provide analgesic and therapeutic effects. In this study, we tested the analgesic effects of high-intensity infrared laser for acupuncture-like stimulation. Twelve adult Sprague–Dawley rats weighing 230 to 250 g were randomly assigned to laser, needle, or restraint groups. Stimulation was directed to the meridian point Taixi (KI 3) for 10 min. For laser stimulation, a pulsed Er:YAG system was used. The laser settings were adjusted to provide a focal raise in the skin temperature to about 45°C. The anti-nociceptive effect was evaluated by the tail-flick test. Both needling and laser stimulation significantly increased the tail-flick latency. Peak needling effect was observed immediately after treatment, while laser stimulation was effective both immediately and 45 min after treatment. High-intensity laser stimulation may be used alternatively or in combination with conventional acupuncture needling for pain relief.
