Abstract

BACKGROUND: Posterior shoulder tightness as demonstrated by glenohumeral internal rotation deficit (GIRD) is a common contributor to many shoulder pathologies in overhead throwing athletes. PURPOSE: This study aimed to assess immediate effect of combining glenohumeral and scapulothoracic mobilization with stretching on improving internal rotation range of motion (ROM) in overhead athletes with GIRD METHODS: This study was a single-blind randomized controlled trial with parallel groups. The participants were 30 asymptomatic male volleyball players who had a loss of shoulder internal rotation ROM of 15 degrees or more on their dominant compared to their nondominant side. They were randomly assigned to 1 of 2 groups: stretching only (n = 15) or stretching plus joint mobilization (n = 15). Participants in the stretching group performed cross-body stretches, and those in stretching plus mobilization group were treated with both cross-body stretching and mobilization techniques for the glenohumeral and scapulothoracic joints. Both groups received the intervention every other day for 1 week. Shoulder internal and external ROM were measured before and after the intervention. RESULTS: Before the intervention, dominant-side deficits in internal rotation ROM compared to the nondominant side were 20.11±5.27 degrees in the stretching group and 21.87±8.06 degrees in the stretching plus mobilization group. After the intervention, internal rotation ROM deficit between the dominant and nondominant side decreased to 11.28±5.82 in the stretching group (P <  0.001) and 10.85±9.19 in the stretching plus mobilization group (P <  0.001). However, the between-group difference was not statistically significant (P = 0.389). External rotation ROM remained unchanged in both groups (P >  0.05). CONCLUSION: Both interventions (stretching and stretching plus mobilization) can have the same beneficial effect in decreasing GIRD in asymptomatic overhead athletes.
联合肩胛肱部和肩胛骨胸部活动与伸展对改善肩胛肱部内旋转缺陷的头顶投掷运动员肩部内旋转的直接效果:一项随机临床试验研究
背景:肩关节内旋缺陷(GIRD)所表现出的后肩紧绷是头顶投掷运动员许多肩部病变的常见原因。目的:本研究旨在评估肩胛骨和肩胛骨联合活动与拉伸对改善GIRD头顶运动员内旋活动范围(ROM)的直接效果。方法:该研究是一项平行组的单盲随机对照试验。参与者是30名无症状的男子排球运动员,他们的主侧与非主侧相比,肩部内旋ROM损失15度或更多。他们被随机分配到两组中的一组:仅拉伸(n = 15)或拉伸加关节活动(n = 15)。拉伸组的参与者进行了跨体拉伸,拉伸加活动组的参与者进行了肩关节和肩胛骨关节的跨体拉伸和活动技术治疗。两组均每隔一天进行干预,持续1周。干预前后分别测量肩关节内外ROM。结果:干预前,与非优势侧相比,拉伸组的内旋ROM优势侧缺损为20.11±5.27度,拉伸+活动组的优势侧缺损为21.87±8.06度。干预后,拉伸组主侧和非主侧的内旋ROM缺损降至11.28±5.82 (P < 0.001),拉伸+活动组为10.85±9.19 (P < 0.001)。但组间差异无统计学意义(P = 0.389)。两组外旋ROM保持不变(P < 0.05)。结论:两种干预措施(拉伸和拉伸+活动)对降低无症状头顶运动员的GIRD具有相同的有益效果。
