It is important to identify the most effective therapeutic modality in the management of myofascial trigger points (MTPt). Thus we aimed to study the effect of therapeutic ultrasound, laser and ischemic compression in reducing pain and improving cervical range of motion among patients with MTPt. Experimental study comparing three groups was designed as a 5 days trial, a co-relational design was considered.
VAS for pain, provocative pain test using "soft tissue tenderness grading scheme" and active cervical lateral flexion using inch tape. Methods- Patients were divided into 3 groups, Gr 1 underwent treatment using therapeutic ultrasound, Gr 2 with therapeutic laser and Gr 3 with ischemic compression. Assessments were done on day 1 and day 5 of treatment respectively.
ANOVA revealed improvement among all 3 groups as statistically significant difference (p<0.05) between the start and end of trial. Analysis using Chi square test shows a statistically significant difference in the improvement between laser and the other 2 groups. Mean difference in the change of scores between the assessments showed laser therapy to have a tendency towards progressive improvement over the treatment period and a better improvement than the other 2 groups. We conclude that laser can be used as an effective treatment regimen in the management of myofascial trigger points thereby reducing disability caused due to musculoskeletal pathology.
确定治疗肌筋膜触发点(MTPt)最有效的治疗方式很重要。因此,我们旨在研究治疗性超声、激光和缺血性按压对减轻MTPt患者疼痛及改善颈椎活动范围的效果。将比较三组的实验研究设计为一项为期5天的试验,并采用相关性设计。
疼痛视觉模拟评分(VAS)、使用“软组织压痛分级方案”的激发性疼痛测试以及用卷尺测量的颈椎主动侧屈。方法:将患者分为3组,第1组采用治疗性超声治疗,第2组采用治疗性激光治疗,第3组采用缺血性按压治疗。分别在治疗的第1天和第5天进行评估。
方差分析显示,所有3组均有改善,试验开始和结束之间存在统计学显著差异(p<0.05)。使用卡方检验分析表明,激光治疗与其他两组之间在改善情况上存在统计学显著差异。评估之间分数变化的平均差异表明,激光治疗在治疗期间有逐渐改善的趋势,且比其他两组改善得更好。我们得出结论,激光可作为治疗肌筋膜触发点的有效治疗方案,从而减少因肌肉骨骼病变引起的功能障碍。
