Shoulder injuries account for up to 17% of all golf related musculoskeletal injuries. One cause may be the repetitive stresses applied to the lead shoulder during the backswing and follow-through phases, which may contribute to the frequency of these injuries. The "elite" golfer may be pre-disposed to developing a shoulder injury based upon the reported adaptations to the glenohumeral joint.
To examine and compare bilateral glenohumeral joint rotational range of motion in elite golfers using standard goniometric procedures.
Twenty-four "elite" male golfers were recruited for this study. Glenohumeral internal (IR) and external rotation (ER) passive range of motion was measured bilaterally at 90° of abduction using a standard universal goniometer. Paired t-tests were utilized to statistically compare the rotational range of motion patterns between the lead and the trailing shoulder.
No statistical differences existed between each shoulder for mean IR or mean ER measures. This finding was consistent throughout different age groups. External rotation measurements were greater than IR measurements in both extremities.
Unlike other sports requiring repetitive shoulder function, the "elite" golfers sampled in this pilot investigation did not demonstrate a unique passive range of motion pattern between the lead and trailing shoulders. Factors, including subjects' age, may have confounded the findings. Further studies are warranted utilizing cohorts of golfers with matching age and skill levels. Additional shoulder range of motion measures should be evaluated.
肩部损伤占所有与高尔夫相关的肌肉骨骼损伤的比例高达17%。一个原因可能是在挥杆上杆和随挥阶段施加于主导肩部的反复应力，这可能导致这些损伤的频发。根据报道的盂肱关节适应性变化，“精英”高尔夫球手可能更容易发生肩部损伤。
使用标准测角程序检查和比较精英高尔夫球手双侧盂肱关节的旋转运动范围。
本研究招募了24名“精英”男性高尔夫球手。使用标准通用测角仪在90°外展位双侧测量盂肱关节内旋（IR）和外旋（ER）的被动运动范围。采用配对t检验对主导肩和非主导肩之间的旋转运动模式进行统计学比较。
各肩部的平均IR或平均ER测量值之间不存在统计学差异。这一发现在不同年龄组中均一致。两侧肢体的外旋测量值均大于内旋测量值。
与其他需要反复使用肩部功能的运动不同，在本次初步调查中抽样的“精英”高尔夫球手在主导肩和非主导肩之间未表现出独特的被动运动范围模式。包括受试者年龄在内的因素可能混淆了研究结果。有必要利用年龄和技能水平匹配的高尔夫球手队列进行进一步研究。还应评估其他肩部运动范围测量指标。
