Résumé : |
Background Subacromial space (SS) narrowing may result in unsafe contact of rotator cuff tendons and bursa with the acromion, possibly promoting rotator cuff pathologies and pain. We measured SS in asymptomatic subjects after three movements employed for shoulder muscles training. Participants and main outcome measures Twenty-five males (age 24+5years; stature 175+8 cm; body mass 74+12 kg) underwent SS ultrasound evaluation while executing with (WL) and without (NL) 4-kg load: 90° shoulder abduction (SA) without humerus rotation (90°neutral); 90° SA maximal humeral external rotation (90°er); maximum SA (above 90°) during upright row (UR). For inter-operator reliability analysis, a subset of 12 subjects was assessed by two operators. Results Intra/inter-operator reliability coefficients were high (ICC>0.87; standard error of measurement range: 0.230.51 mm; minimum detectable change range: 0.611.79 mm). ANOVA revealed significant differences between loads (p = 0.003, η2 = 0.37) and angles (p Conclusions When holding a 4-kg load, SS is larger at 90°er than at 90°neutral and UR shoulder abduction positions. In unloaded condition, SS at 90°neutral is reduced compared to 90°er and UR. |
