Abstract

OBJECTIVE

This study compared the effects of 90 s of manual compressive therapy (MCT) on latent myofascial trigger points (LTPs) for 3 sessions per week for 4 weeks to determine changes in individual pressure pain threshold (PPT). A total of 30 (15 males, 15 females; age = 22 ± 4 y/o, height = 175 ± 18 cm, weight = 162.5 ± 57.5 kg) symptomatic subjects with LTPs volunteered for the study.

METHODS

PPT was measured at baseline and pre- and post-treatment for all 12 sessions with a pressure algometer across the 4-week treatment time frame. The MCT was applied to the control group on their LTP at pressure intended to provide a sham condition (1/10 on verbalized analog scale (VAS)). Two experimental groups had MCT applied either directly on the LTP (d-TP) or in close-proximity to their LTP (cp-TP) at moderate pressure (7/10 on VAS).

RESULTS

There was a significant increase in PPT from the first through twelfth treatment sessions (p < 0.001, partial η = 0.914). A significant increase in PPTs between treatment groups was acutely observed from pre- to post-therapy tests (p = 0.001, partial η = 0.146). The differences between pre- versus post-treatment PPT measures indicated significant differences (d-TP vs. control, p < 0.001; cp-TP vs. control, p = 0.007). No differences were observed between experimental groups (p = 0.215).

CONCLUSIONS

PPT continued to increase after several weeks of MCT when applied directly on or within 2.5 cm of an identified LTP compared to control.

摘要

目的

本研究比较了每周3次、共4周、每次90秒的手动压迫疗法(MCT)对潜在肌筋膜触发点(LTP)的影响,以确定个体压力疼痛阈值(PPT)的变化。共有30名有LTP症状的受试者(15名男性,15名女性;年龄=22±4岁,身高=175±18厘米,体重=162.5±57.5千克)自愿参加该研究。

方法

在为期4周的治疗时间内,使用压力痛觉计在基线以及所有12次治疗的治疗前和治疗后测量PPT。对对照组的LTP施加MCT,压力旨在提供一种假治疗条件(言语类比量表(VAS)评分为1/10)。两个实验组分别以中度压力(VAS评分为7/10)将MCT直接应用于LTP(d-TP)或紧邻LTP(cp-TP)。

结果

从第一次治疗到第十二次治疗,PPT显著增加(p<0.001,偏η=0.914)。在治疗前和治疗后测试中,急性观察到治疗组之间的PPT显著增加(p=0.001,偏η=0.146)。治疗前与治疗后PPT测量值之间的差异表明存在显著差异(d-TP与对照组相比,p<0.001;cp-TP与对照组相比,p=0.007)。实验组之间未观察到差异(p=0.215)。

结论

与对照组相比,当MCT直接应用于已识别的LTP上或其2.5厘米范围内时,数周后PPT持续增加。
