Overhead athletes are subject to adaptations in the shoulder including glenohumeral internal rotation deficit (GIRD). It has been documented that this alteration is more evident in overhead athletes with pain. Our objective was to compare glenohumeral rotation motion between symptomatic and asymptomatic handball players.
Glenohumeral rotation range of motion, GIRD, external rotation gain (ERG), and total rotation motion were determined with a standard goniometer in 30 handball players with pain and 27 without pain. Differences between the throwing and non-throwing shoulder were determined in each group.
Handball players with pain had significantly greater GIRD (P = .002), ERG (P = .027), and external rotation in the throwing arm (P = .042) and lesser internal rotation in the throwing arm (P = .029) in comparison to the athletes without pain. Comparisons between limbs exhibited a significant difference in the 2 groups regarding internal and external rotation (P < .02), but differences within the group with pain were greater. Differences were not found in the total rotation motion between the 2 groups.
Handball players showed specific adaptations in the throwing shoulder; in particular, handball players with pain have greater GIRD, ERG, and external rotation and lesser internal rotation of the throwing shoulder.
过顶运动员的肩部会发生适应变化,包括肩盂肱关节内旋不足(GIRD)。有文献记载,疼痛的过顶运动员这种改变更为明显。我们的目的是比较有症状和无症状手球运动员的肩肱关节旋转运动。
使用标准量角器测量 30 名有疼痛的手球运动员和 27 名无症状运动员的肩肱关节旋转活动范围、GIRD、外旋增益(ERG)和总旋转运动。在每组中确定投掷肩和非投掷肩之间的差异。
与无症状运动员相比,有疼痛的手球运动员的 GIRD(P=.002)、ERG(P=.027)和投掷臂的外旋(P=.042)明显更大,而投掷臂的内旋(P=.029)明显更小。两组之间的肢体比较显示在内外旋转方面存在显著差异(P<.02),但疼痛组的差异更大。两组之间的总旋转运动无差异。
手球运动员在投掷肩表现出特定的适应性;特别是,有疼痛的手球运动员的 GIRD、ERG 和外旋更大,而投掷肩的内旋更小。
