Measurement of Glenohumeral Internal Rotation in Asymptomatic Tennis Players and Swimmers

摘要: BackgroundGlenohumeral internal rotation deficit, often diagnosed in players of overhead sports, has been associated with the development secondary shoulder lesions.HypothesisAsymptomatic different sports will exhibit variable degrees glenohumeral deficit.Study DesignCross-sectional study; Level evidence, 3.MethodsFifty-four asymptomatic male volunteers (108 shoulders) divided into 3 groups (tennis players, swimmers, control group) underwent measurements and external using clinical examination scapular stabilization. Measurements dominant nondominant shoulders were compared within between groups. Glenohumeral deficit (GIRD) was defined as difference shoulders.ResultsIn tennis mean GIRD 23.9° ± 8.4° (P < .001); 12° 6.8° group, 4.9° 7.4° = .035). Dominant showe...
