어깨관절 내적 충돌증후군을 가진 청소년기 야구선수들의 ROM, 근력, 기능수행정도에 미치는 운동과 도수치료를 혼합한 중재들의 효과 비교 = Comparison of Effects of Manual Therapy Interventions Combined with Exercise on Range of Motion, Muscle Strength, and Functional Performance in Adolescent Baseball Players with Internal Impingement of Shoulder Joint

다국어 초록 (Multilingual Abstract)

Purpose : The purpose of this study was to identify the comparison of the effects of manual therapy combined with exercise on range of motion (ROM), muscle strength, and functional performance in adolescent baseball players with internal impingement syndrome of the shoulder.
Methods : The subjects were 30 patients diagnosed with impingement syndrome of the shoulder. Thirty subjects are randomly assigned to each 3 different groups; Group 1. (exercise group), Group 2. (exercise+mobilization; EMOB group), Group 3. (exercise+mobilization with movement; EMWM group). The interventions were performed three times a week for 4 weeks. The main outcome measures were goniometer, Biodex dynamometer, and Korean Kerlan Jobe shoulder-elbow (K-KJOC) scores. The ROM (external and internal rotation), muscle strength (external and internal rotation: 60 °/sec., 180 °/sec.), and functional performance were compared among the groups.
Results : No significant difference was observed among the groups in the range of external rotation of the shoulder before and after the intervention, but the range of internal and total rotation was significantly increased in Group 2, 3 compared to Groups 1. Muscle strength of external and internal rotation (60 °/sec., 180 °/sec.) was not significantly different among Group 1, 2, 3, and functional performance was significantly increased in Group 2, 3 compared to Group 1. However, there was no significant difference between Group 2 and Group 3 in all measurements.
Conclusion : An intervention with manual therapy such as EMOB and EMWM was more effective than exercise alone for rapid recovery from shoulder injury and improvement in functional performance. However, further efforts are needed to identify effects of specific interventions with manual therapy.
