Background We examined what muscles were related to the Elbow Push Test (EPT). The results of the EPT may have reflected the strength of the serratus anterior muscle. Validation of the timing of the contraction of these muscles may be important diagnostic factors for individuals with shoulder disorders. Methods For 21 healthy individuals, the muscular force required to perform the EPT, as well as the strength of the trunk rotators, serratus anterior muscle, and external and internal rotators were measured using a hand-held dynamometer. We evaluated the relationship between the results of the EPT and the strength of each muscle. Results The results of the EPT may have reflected the strength of the serratus anterior muscle. Conclusions Validation of the timing of the contraction of these muscles may be important diagnostic factors for individuals with shoulder disorders.
