Thumb carpometacarpal osteoarthritis (CMC OA) is a common disorder that interferes with the ability to perform the activities of daily life. The purpose of this study was to investigate the immediate effects of ischemic compression on myofascial trigger points (MTrPs) in the first dorsal interosseous (FDI) muscle in patients with the diagnosis of thumb CMC OA.
In a quasi-experimental clinical trial, thirty-one patients, 87% female (age: 82 ± 9.4 years), with thumb CMC OA, were consecutively assigned to either an experimental treatment that included the ischemic compression of the FDI MTrP or a sham treatment of the FDI MTrP for one session. The main outcome considered in the study was the pressure pain threshold (PPT). Measurements were taken pre- and post-treatment and at a 1-week follow-up period.
The PPT over the right (affected) FDI muscle showed statistically significant differences between groups at 1-week follow up (F = 3.518; = 0.04) in favor of the experimental group.
The ischemic compression of FDI-MTrPs is an appropriate part of a multimodal treatment to decrease local pain sensitivity in patients with CMC OA.
拇指腕掌关节骨关节炎（CMC OA）是一种常见的疾病，会干扰日常生活活动的能力。本研究的目的是探讨缺血性压迫对诊断为拇指 CMC OA 患者第一背间骨间肌（FDI）肌筋膜触发点（MTrP）的即刻影响。
在一项准实验性临床试验中，连续纳入 31 名女性（87%，年龄：82 ± 9.4 岁）拇指 CMC OA 患者，将其分为实验组（接受 FDI MTrP 的缺血性压迫治疗）和对照组（接受 FDI MTrP 的假治疗），每组 16 人。研究的主要结局考虑是压力疼痛阈值（PPT）。在治疗前、治疗后和 1 周随访时进行测量。
在 1 周随访时，右侧（患侧）FDI 肌肉的 PPT 在组间存在统计学差异（F = 3.518；p = 0.04），实验组更优。
FDI-MTrP 的缺血性压迫是 CMC OA 患者多模式治疗中降低局部疼痛敏感性的一个合适部分。
