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.
