摘要

Background and purpose: The elbow related sports injuries were often taken place on baseball players. Most of reasons were overuse, insufficient flexibility, or muscle tightness. Those reasons may influence joint range of motion of elbow in baseball players. So it is necessary to evaluate the elbow range of motion for baseball players during clinician were involved with the care of the athletes. Therefore, the purpose of this study was to compare the difference of the elbow range of motion between baseball players and normal subjects. Methods: Forty-four subjects (22 baseball players and 22 normal subjects) were participated in the study. The measurement of elbow range of motions including flexion/extension, pronation/supination, and valgus was used by a goniometer. The flexion-extension total range and pronation-supination total range were calculated from the flexion degree subtract the extension degree and pronation degree plus the supination degree, separately. Both of sides of elbows were evaluated. The independent T-test was used to compare the difference of elbow range of motion between baseball players and normal subjects. Results and Discussion: The result was showed that the significantly different between baseball players and normal subjects in elbow flexion, extension, supination, and pronation-supination total range at dominated-side (p＜.05). There was no significant difference between baseball players and normal subjects in elbow pornation, valgus, and flexion-extension total range at dominated-side (p＞.05). All of elbow data measured from non-dominated side of elbow were found no significantly difference between baseball players and normal population (p＞.05). It revealed that baseball players had insufficient range of motion in elbow flexion, extension, and supination that resulted in poor flexibility in dominated elbow. It would raise higher elbow injuries incidence when the flexibility of elbow decreased. Conclusion: The baseball players had found poor flexibility in dominated elbow. It needed to stretch more and soften the muscle tightness of the dominated elbow to prevent the elbow injuries occurring in baseball players.
