We hypothesized that latent MTrPs might decrease gluteus medius muscle strength in healthy individuals. This study aimed to investigate the relationship between latent MTrPs and gluteus medius muscle strength in a group of healthy adults.
Forty-eight healthy men were included in the study. Trigger point examination for the gluteus medius was performed bilaterally. Subjects with one or more trigger points on the dominant side and those without any trigger point were assigned to two groups. Muscle strength for the gluteus medius was assessed with a manual muscle tester using the "break test" technique on both sides. For statistical analysis, the independent sample t-test was used to compare the intergroup differences.
The latent MTrP group demonstrated lower abduction muscle strength in the dominant gluteus medius. Moreover, the latent MTrP group showed higher abduction muscle strength in the non-dominant gluteus medius (p < 0.05). Intergroup comparison revealed that gluteus medius abduction muscle strength on the dominant side was higher in the non-latent MTrP group (p < 0.05).
Latent MTrP may cause joint movement limitation, overload by affecting motor activation patterns and reciprocal inhibition mechanisms. Outcomes of the current study revealed that gluteus medius abduction strength values below 9.7 kg could be associated with latent MTrP with high sensitivity and low specificity. It is imperative to note that the latent MTrP of gluteus medius muscle, which has a critical role in the lumbopelvic junction, should not be ignored in clinical practice, and treatment should be applied when detected.
我们假设潜在的肌筋膜触发点可能会降低健康个体的臀中肌力量。本研究旨在调查一组健康成年人中潜在的肌筋膜触发点与臀中肌力量之间的关系。
研究纳入了 48 名健康男性。对臀中肌进行触诊检查，双侧均进行。将优势侧有一个或多个触发点和没有触发点的受试者分为两组。使用手动肌肉测试器，采用“断裂测试”技术评估臀中肌的肌肉力量，双侧均进行。为了进行统计分析，使用独立样本 t 检验比较组间差异。
潜在的肌筋膜触发点组在优势侧的臀中肌外展力量较低。此外，潜在的肌筋膜触发点组在非优势侧的臀中肌外展力量较高（p<0.05）。组间比较显示，非潜在的肌筋膜触发点组在优势侧的臀中肌外展力量较高（p<0.05）。
潜在的肌筋膜触发点可能通过影响运动激活模式和交互抑制机制导致关节运动受限和过载。本研究的结果表明，臀中肌外展力量值低于 9.7kg 可能与潜在的肌筋膜触发点高度相关，具有较高的敏感性和较低的特异性。需要注意的是，在临床实践中，不应忽视在腰骶关节中起关键作用的臀中肌的潜在肌筋膜触发点，当检测到触发点时应进行治疗。
