To determine if a glenohumeral joint internal rotation range of motion difference (IRD) and external rotation difference (ERD) exists between dominant and non-dominant shoulders of cricketers as demonstrated in other overhead sports, and, if present, to establish if differences exist between cricketers with and without a history of gradual onset non-specific shoulder pain.
An observational study.
Non-clinical, at national cricket indoor training venues.
One hundred and nine elite male and female cricketers (11-35 years), representing 97% of the England and Wales national and West of England regional Under 13 teams, consented. The final number included for data analysis was 133.
Data relating to playing position, cricket exposure, shoulder pain and demographic details collected using a questionnaire. Passive isolated glenohumeral rotation measured in 90 degrees shoulder abduction using an inclinometer.
Cricketers who regularly bowl or throw overarm had significantly less internal (-7.9 degrees , p<0.001) and greater external (8.6 degrees , p<0.001) dominant to non-dominant glenohumeral rotation. Wicket-keepers had tendencies for smaller differences that were still statistically significant [mean IRD -5.9 degrees (p<0.001); ERD 5.0 degrees (p=0.002)]. Cricketers who experienced shoulder pain demonstrated a significantly greater IRD [mean 3.2 degrees (p=0.032)] than those who did not.
The results of this study support measurement of passive glenohumeral joint rotation during musculoskeletal profiling and indicate that a possible link between increased IRD and non-specific shoulder pain warrants further investigation.
确定板球运动员优势肩和非优势肩之间是否存在盂肱关节内旋活动度差异(IRD)和外旋差异(ERD),正如在其他过头运动中所表现的那样;如果存在差异,则确定有和没有逐渐起病的非特异性肩痛病史的板球运动员之间是否存在差异。
一项观察性研究。
在国家板球室内训练场地进行的非临床研究。
109名精英男女板球运动员(11 - 35岁),代表了英格兰和威尔士国家及英格兰西部地区13岁以下球队的97%,他们同意参与研究。纳入数据分析的最终人数为133人。
使用问卷收集与比赛位置、板球运动经历、肩部疼痛和人口统计学细节相关的数据。使用倾角仪在肩部外展90度时测量被动孤立的盂肱关节旋转。
经常投球或进行过肩投掷的板球运动员,其优势肩与非优势肩的内旋活动度明显更小(-7.9度,p<0.001),外旋活动度明显更大(8.6度,p<0.001)。守门员的差异较小,但仍具有统计学意义[平均IRD -5.9度(p<0.001);ERD 5.0度(p = 0.002)]。经历过肩部疼痛的板球运动员的IRD明显更大[平均3.2度(p = 0.032)],高于未经历过肩部疼痛的运动员。
本研究结果支持在肌肉骨骼评估过程中测量被动盂肱关节旋转,并表明IRD增加与非特异性肩痛之间可能存在联系,值得进一步研究。
