Effectiveness of modified sleeper stretch with strengthening exercise to reduce pain and increase the internal rotation of shoulder joint among volleyball players

BACKGROUND : The volleyball players need pain free and muscular strength for their playing games. The stretching and strengthening exercise for high school male volleyball players is important to maintain healthy body and it will improve the playing level. OBJECTIVES : To assess the effects of modified sleeper stretch and strengthening exercise to reduce pain and increase internal rotation of shoulder joint among volleyball players performance among male high school students. METHODS : Asymptomatic subjects 20 male athlete participated in the study. The control group (n-10) is only for screening and experimental group (n-10) underwent stretch and strengthening exercise. Shoulder internal rotation ROM, with the arm abducted to 90 degree and scapula prevented, was measured before and after 6 weeks intervention period. while subjects in the experimental group were asked to perform stretching exercise with strengthening exercise on the more limited side only, once daily for 3 repitations, holding each stretch for 30 seconds. RESULTS : The improvements in internal rotation for the subjects in the experimental group were significantly greater than for the subjects in the control group. CONCLUSION : The modified sleeper stretch with strengthening exercise in individual with limited pain and shoulder internal rotation ROM appears to be more effective than no stretching in control without internal rotational asymmetry to improve shoulder internal rotation ROM.
