: Suprascapular neuropathy is more frequent in volleyball as compared to other overhead sports. This study aims to report the actual prevalence of suprascapular neuropathy among elite volleyball players. The hypothesis is that becoming jump topspin serves the most common serving technique, suprascapular neuropathy reduced its frequency. : A total of 82 professional players were enrolled in the study. The presence of symptoms and the type of serve preferably performed were investigated. The strength and trophicity of the supraspinatus and infraspinatus muscles were evaluated. Patients with positive clinical findings underwent MRI of the shoulder. : The jump topspin serve was found to be the most popular type of serve both in males and females. At physical examination, 9% of the males and 12% of the females presented with infraspinatus muscle hypotrophy. Each case was accompanied by external rotation weakness. None of them complained of pain or reduced performance when they played. MRI confirmed infraspinatus muscle atrophy in all subjects. : A lower prevalence of suprascapular neuropathy was found as compared with that previously reported in the 1980s and 1990s. A reduction in the popularity of the float serve seems to be a possible explanation. Thus, the jump topspin serve could be safe for suprascapular neuropathy and associated injuries in volleyball. The findings of this study should be considered by athletes and coaches for the prevention of activity-related injuries.
: 与其他过顶运动相比，排球运动员更容易发生肩胛上神经病变。本研究旨在报告精英排球运动员中肩胛上神经病的实际患病率。假设是，作为最常见的发球技术之一的跳起上手发球，其使用频率会因肩胛上神经病变而降低。 : 共有 82 名职业运动员参与了这项研究。研究调查了症状的存在和首选的发球类型。评估了冈上肌和冈下肌的力量和营养状况。有阳性临床发现的患者接受了肩部 MRI 检查。 : 跳起上手发球是男性和女性中最受欢迎的发球类型。在体格检查中，9%的男性和 12%的女性出现冈下肌萎缩。每个病例均伴有外旋肌无力。他们在打球时都没有抱怨疼痛或表现下降。MRI 证实所有受试者均存在冈下肌萎缩。 : 与 20 世纪 80 年代和 90 年代报道的患病率相比，肩胛上神经病的患病率较低。浮动发球的流行度降低似乎是一个可能的解释。因此，跳起上手发球可能对排球中的肩胛上神经病和相关损伤是安全的。本研究的发现应引起运动员和教练的重视，以预防与活动相关的损伤。
