Abstract：
Background and Objectives: Neck and shoulder injuries are common in Brazilian ju-jitsu (BJJ) athletes, and scapular dyskinesis (SD) is associated with these injuries. This study aimed to investigate the prevalence of SD in BJJ athletes, their neck and shoulder function and strength, and the BJJ training period. Materials and Methods: Forty-eight BJJ athletes participated in the study. Years of experience with BJJ, belt, shoulder internal and external rotation strength, neck strength, neck disability index (NDI), and SD were measured. Results: Approximately 31 BJJ athletes (64.6%) showed SD, and the nondominant arm showed a more obvious SD (n = 22, 45.8%) than the dominant arm (n = 18, 37.5%). Those with over five years of BJJ training experience showed a significantly higher rate of SD (p = 0.006) than those with less than five years of experience. Shoulder isometric internal rotation strength was significantly weaker in the obvious SD group than in the normal SD group (p = 0.014). Neck isometric strength and NDI did not differ significantly between individuals with or without SD. Conclusions: SD was common among BJJ athletes, and more experienced BJJ athletes exhibited higher rates of SD. Shoulder rotational strength was weaker with SD. Further studies are necessary on the neck and shoulders of BJJ athletes with SD.
摘要：
背景和目的：颈部和肩部受伤在巴西柔术（BJJ）运动员中很常见，肩胛骨皮肤发育不良（SD）与这些损伤有关。本研究旨在调查BJJ运动员中SD的患病率，他们的颈部和肩部功能和力量，还有BJJ训练期.材料和方法：48名BJJ运动员参加了研究。多年的BJJ经验，腰带,肩部内部和外部旋转强度，颈部强度,颈部残疾指数（NDI），测量SD。结果：大约31名BJJ运动员(64.6%)表现出SD，非优势臂的SD（n=22，45.8％）比优势臂（n=18，37.5％）更明显。具有超过五年BJJ培训经验的人的SD率（p=0.006）明显高于具有少于五年经验的人。明显SD组肩等轴内旋强度明显弱于正常SD组(p=0.014)。有或没有SD的个体之间的颈部等距强度和NDI没有显着差异。结论：SD在BJJ运动员中很常见，更有经验的BJJ运动员表现出更高的SD率。肩关节旋转强度随SD而减弱。需要对患有SD的BJJ运动员的颈部和肩部进行进一步的研究。
