摘要

研究目的：本研究探討以波長830nm或980nm、持續性輸出、聚集式低能量雷射對大白兔骨骼肌肌筋膜激痛點之效應。研究方法：以37隻紐西蘭大白兔分為3組，分別給予波長830nm的雷射治療(6焦耳/腳/天)、波長980nm的雷射治療(6焦耳/腳/天)、對照組(0焦耳/腳/天)的治療共5天。在治療前、第一次及第五次治療後以肌電圖針測量每一肌筋膜激痛點的終板電板(endplate noise, EPN)的盛行率。研究結果：各組的終板電板盛行率隨時間而減少。但於第一次治療後或第五次治療後三組間並無差異。結論：三組的肌筋膜激痛點的盛行率於第一次治療後及第五次治療後都出現下降情形，但三組間並沒有統計上的差異。此結果表示，以此設定模式的叢集式低能量雷射對於大白兔骨骼肌肌筋膜激痛點抑制效應(inhibitory effect)，兩組實驗組均無法優於對照組。

Objective: This study investigated the effect of cluster probe low level laser therapy (LLLT) with a continuous wavelength of 830 nm or 980 nm on the myofascial trigger spot (MTrS) in rabbit skeletal muscle, an animal model of myofascial pain syndrome (MPS). Methods: Thirty-seven New Zealand rabbits with MTrSs in the thigh muscle were divided into three groups and were given placebo treatment (0 J/leg/day), 830 nm LLLT (6 J/leg/day), and 980 nm LLLT (6 J/leg/day), respectively, for 5 days. Electromyographic studies were used to evaluate the endplate noise (EPN) prevalence in each MTrS before treatment, on the first and fifth day after therapy. Results: EPN prevalences decreased in all groups over time (p＜0.05). However, there were no statistical differences among the three groups on the first or fifth day after therapy (p＞0.05). Conclusion: EPN in the rabbits' MTrSs in all three groups decreased on the first and fifth day after therapy but there were no statically significant differences among them. These results indicated that the cluster probe LLLT used in this study did not have a significantly better inhibitory effect on the rabbits' MTrSs than placebo therapy.
