Quantitative thermal sensory and pain threshold testing (QST) was performed in 29 adult healthy volunteers (mean age 24.2 +/- 2.7 years; range: 18-29 years; 20 females, 9 males) using the Thermal Sensory Analyser TSA-II (Medoc Advanced Medical Systems, Ramat Yishai, Israel, and Minneapolis, Minnesota, USA) before and after laser needle acupuncture and placebo stimulation, respectively. Significant (p < or = 0,001; t-test) gender-specific differences were seen on cold pain threshold analysis. No significant changes in parameters of thermal sensory and pain thresholds were found before and after laser needle or placebo stimulation at acupuncture points for acute pain. However, a trend towards change in the median value of cold pain sensation after laser needle stimulation (p = 0.479; paired t-test; n.s.) was seen within the group of healthy females. The influence of stimulation of acupuncture points for chronic pain on the various parameters needs to be clarified in future studies.
分别在29名成年健康志愿者（平均年龄24.2±2.7岁；范围：18 - 29岁；20名女性，9名男性）身上，于激光针刺和安慰剂刺激前后，使用热感觉分析仪TSA-II（Medoc Advanced Medical Systems，以色列拉马特伊沙伊以及美国明尼苏达州明尼阿波利斯）进行定量热感觉和疼痛阈值测试（QST）。在冷痛阈值分析中观察到显著的（p≤0.001；t检验）性别特异性差异。在急性疼痛的穴位进行激光针刺或安慰剂刺激前后，热感觉和疼痛阈值参数未发现显著变化。然而，在健康女性组中，激光针刺刺激后冷痛感觉的中位数有变化趋势（p = 0.479；配对t检验；无统计学意义）。针刺穴位对慢性疼痛各种参数的影响有待未来研究阐明。
