胸锁乳突肌扳机点疼痛部位及其性别因素分析

Pain sites in the sternocleidomastoid muscle trigger points and the gender-related factors

目的研究胸锁乳突肌乳突部扳机点疼痛分布特征及其性别因素。方法采用定量按压法,按其乳突附着部的前、中、后三部分,对不同年龄段男女健康受试者胸锁乳突肌乳突部的扳机点进行检查,采取VAS疼痛量化评分评定疼痛程度。结果(1)老年男性组VAS疼痛评分为5.226±0.331,老年女性组VAS疼痛评分为5.531±0.379;组别间差异无显著性(P>0.05);(2)青年男性组VAS疼痛评分为2.940±0.331,青年女性组VAS疼痛评分为3.982±0.405;组别间差异无显著性(P>0.05);(3)胸锁乳突肌在乳突前与乳突中、乳突中与乳突后的疼痛比较差异有显著性(P<0.05);乳突前与乳突后差异无显著性(P>0.05)。结论胸锁乳突肌乳突部扳机压痛在性别间差异无显著性,胸锁乳突肌乳突部扳机点疼痛以乳突前和乳突后最为明显。

Objective To study gender-related factors in the painful sites and degree of pains in the trigger points of the sternocleidomastoid muscle. Methods The trigger points of the sternocleidomastoid muscle of healthy volunteers of either gender with different ages were examined by measurable pressure using the right thumb, and the pain degree was assessed with visual analog scale (VAS). Result The VAS score was 5.226±0.331 in senior male subjects and 5.531±0.379 in senior female subjects, without significant differences between them (P>0.05). Nor was significant difference detected between the scores of young male and female subjects (2.940±0.331 vs 3.982±0.405, P>0.05). In terms of the pain severity, the difference was significant between the medial and anterior areas and between the medial and posterior areas of the mastoid process (P<0.05), but not between the anterior and posterior areas of the mastoid process (P>0.05). Conclusion There is no significant gender-related difference in the pain in the trigger points of the sternocleidomastoid muscle elicited by compression with the right thumb. The anterior and posterior areas of the mastoid process are relatively sensitive to compression pain.
