Abstract

Objectives

The objective of this cross-sectional study was to determine the association between lateral epicondylalgia (LE) and trigger points (TrPs) in the supraspinatus, infraspinatus, and triceps muscles.

Methods

A total of 26 subjects, aged 18-60 years, diagnosed with LE, were included in the study. The presence of TrPs in the supraspinatus, infraspinatus, and triceps muscles on both the affected and unaffected sides was assessed. The association and strength of the association between LE and TrPs were analyzed using the chi-square test and Cramer's V criteria, respectively.

Results

Significant associations were observed between LE and TrPs in the triceps muscle (LE-R / TTrPs-R chi-square (X2): 4.625, P - .032, Cramer's V: 0.422; LE-L / TTrPs-L X2: 16.611, p-<.001, Cramer's V: 0.799), the infraspinatus muscle (LE-R / ITrPs-R X2: 6.406, P - .011, Cramer's V: 0.496; LE-L / ITrPs-L X2: 3.630, P - .057, Cramer's V: 0.374).the supraspinatus muscle (LE-R / STrPs-R X2: 3.957, P - .047, Cramer's V: 0.390; LE-L / STrPs-L X2: 6.851, P - .009, Cramer's V: 0.513). The unaffected side showed a negative association of TrPs.

Conclusions

Lateral epicondylalgia was associated with infraspinatus, triceps and, supraspinatus TrPs. There was no association with TrPs on the unaffected side.

外上髁痛患者冈上肌、冈下肌和三头肌触发点的关联：一项横断面研究

目的：本横断面研究的目的是确定外侧上髁痛（LE）与冈上肌、冈下肌和三头肌的触发点（TrPs）之间的关系。方法选取年龄在18 ~ 60岁的LE患者26例进行研究。评估了患侧和未患侧冈上肌、冈下肌和三头肌中TrPs的存在。分别采用卡方检验和Cramer's V标准分析LE与TrPs之间的关联及其强度。结果LE和TrPs在肱三头肌中存在显著相关性(LE- r / TTrPs-R卡方（X2）： 4.625, P - 0.032, Cramer’s V: 0.422；LE-L / ITrPs-L X2: 16.611, p- 0.01, Cramer's V: 0.799)，冈下肌（LE-R / ITrPs-R X2: 6.406, p- 0.011, Cramer's V: 0.496; LE-L / ITrPs-L X2: 3.630, p- 0.057, Cramer's V: 0.374）。冈上肌（LE-R / STrPs-R X2: 3.957, P - 0.047, Cramer's V: 0.390; LE-L / STrPs-L X2: 6.851, P - 0.009, Cramer's V: 0.513）。未受影响的一侧显示TrPs呈负相关。结论侧上髁痛与冈下肌、肱三头肌和冈上肌trp有关。在未受影响的一侧，与trp无关。
