探討以叢集式低能量雷射對於大白兔肌筋膜激痛點之效應：個案控制型研究
Abstract
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.
