Clinical Measures of Shoulder Mobility in the Professional Baseball Player.

摘要: Context: Professional baseball players must achieve a delicate balance between shoulder mobility and stability to attain optimal sports performance. The sport-specific demands of repetitive overhead throwing may result in an altered mobility-stability relationship.Objective: To evaluate clinical measures professional order examine differences the nonthrowing shoulders describe chronic adaptations throwing.Design: Descriptive.Setting: athletic training room at Maryvale Baseball Park, Phoenix, AZ.Patients or Other Participants: Twenty-seven (20 pitchers, 7 position players; age = 20 +/- 1.6 years, height 190.5 4.8 cm, mass 91.6 9.6 kg) with no previous history elbow injury.Main Outcome Measure(s): We recorded scapular upward rotation 4 levels humeral elevation plane (rest, 60 degrees , 90 120 ); posterior tightness; passive, isolated glenohumeral joint internal external range motion.Results: Scapular was significantly greater (14.2 6.5 ) than (10.6 6.1 (P .04). observed statistically significant difference tightness (30.2 4.6 cm) (28.0 .09). In addition, exhibited decrease (56.6 12.5 compared (68.6 12.6 .001), concomitant increase (throwing 108.9 9.0 101.9 5.9 P .0014). An analysis total arc motion (internal + rotation) revealed sides .15).Conclusions: shoulder. Further research is necessary determine relation these adaptive changes, if any, injury disability.
