Racquet sports, especially lawn tennis and badminton have been gaining popularity in Asian countries like India. With this increase in popularity, the injury rate in the sport has also increased.
The study will help detect the presence of gleno-humeral movement dysfunction and scapular resting position abnormality in asymptomatic racquet players, thus providing basis for screening the players and allow the clinician to determine if the asymmetry is a normal adaptation in the player or an abnormal change associated with injury.
46 asymptomatic professional players were divided into a study group of 23 players (16 tennis and 7 badminton) and control group of 23 football players. Assessment of passive gleno-humeral range of motion and distance of spine and inferior angle of scapula from corresponding spinous process were measured bilaterally and between groups.
There was statistically significant reduction in range of internal rotation (62.17 ± 8.09), extension (39.78 ± 4.12) and an increase in the external rotation (106.95 ± 7.49) of dominant compared to non-dominant arm of racquet players and a statistically significant decrease in internal rotation (78.69 ± 10.24), extension (44.78 ± 3.19), adduction (37.39 ± 6.54) and an increase in external rotation (102.6 ± 5.19) of dominant arm of racquet players compared to football players. Study also showed statistically significant increase in the spino-scapular distance at the level of inferior angle of scapula (10.23 ± 1.43) on dominant side compared to non-dominant.
The dominant side scapula of asymptomatic racquet players showed increased external rotation and elevation as compared to the non-dominant side. Also, reduced shoulder internal rotation, extension and adduction and gain in shoulder external rotation was observed on the dominant side of racquet players when compared to the control group.
球拍类运动，尤其是草地网球和羽毛球，在印度等亚洲国家越来越受欢迎。随着这项运动受欢迎程度的提高，其受伤率也有所上升。
本研究将有助于检测无症状球拍类运动员是否存在盂肱关节运动功能障碍和肩胛骨静止位置异常，从而为运动员筛查提供依据，并让临床医生确定这种不对称是运动员的正常适应还是与损伤相关的异常变化。
46名无症状职业运动员被分为一个由23名运动员组成的研究组（16名网球运动员和7名羽毛球运动员）和一个由23名足球运动员组成的对照组。双侧测量并比较两组之间的被动盂肱关节活动范围以及脊柱与肩胛骨下角到相应棘突的距离。
与球拍类运动员的非优势手臂相比，优势手臂的内旋范围（62.17±8.09）、伸展范围（39.78±4.12）有统计学意义的降低，外旋范围（106.95±7.49）增加；与足球运动员相比，球拍类运动员优势手臂的内旋范围（78.69±10.24）、伸展范围（44.78±3.19）、内收范围（37.39±6.54）有统计学意义的降低，外旋范围（102.6±5.19）增加。研究还显示，与非优势侧相比，优势侧肩胛骨下角水平的棘突-肩胛骨距离（10.23±1.43）有统计学意义的增加。
与非优势侧相比，无症状球拍类运动员的优势侧肩胛骨外旋和抬高增加。此外，与对照组相比，球拍类运动员优势侧的肩部内旋、伸展和内收减少，肩部外旋增加。
