Effects of Shoulder Rehabilitation Exercise on Range of Motion, Muscle Activity, Muscle Tone and Manual Muscle Strength after Arthroscopic Bankart Repair in Elite Collegiate Rowing Athlete: Case Report

OBJECTIVES The purpose of this study was to evaluate the effects of shoulder rehabilitation exercise on range of motion (ROM), muscle activity, muscle tone and manual muscle strength after arthroscopic bankart repair in elite collegiate rowing athlete.METHODS A 22-year-old elite collegiate rowing athlete with nerve decompression surgery for scapular entrapment syndrome in 2019, and arthroscopic bankart repair in 2021 was enrolled in this case study. Shoulder rehabilitation exercise program was received weight bearing and elastic band exercises, and was performed for 50 min/day, and 3 day/week for 8 weeks. ROM (flexion, extension, abduction, internal rotation, external rotation), muscle activity, muscle tone and manual muscle strength (infraspinatus; IFP, teres minor; TM, biceps; BI, lateral deltoid; LD, supraspinatus; SSP, upper trapezius; UT) were measured before, after 4 and 8 weeks of shoulder rehabilitation exercise.RESULTS Shoulder ROM increased at flexion, extension, abduction, internal rotation, external rotation after shoulder rehabilitation exercise. Muscle tone increased at IFP, TM, LD, SSP, and UT, but BI decreased after shoulder rehabilitation exercise. Muscle activity and manual muscle strength increased at IFP, TM, BI, LD, SSP, UT after shoulder rehabilitation exercise.CONCLUSIONS The results of this case report confirmed that shoulder rehabilitation exercise had a positive effect on the muscular physiological indices after arthroscopic bankart repair in elite collegiate rowing athlete.
