Effects of Modified Sleeper Stretch Versus Modified Cross-Body Stretch on Posterior Shoulder Pain and Performance Measures Among Badminton Players

Abstract

Introduction. Shoulder joint, being highly mobile, is particularly vulnerable to overuse injuries in overhead athletes. Posterior shoulder pain in these individuals is commonly associated with Glenohumeral Internal Rotation Deficit (GIRD), which can adversely affect performance and functional ability. The present study compared the effectiveness of the modified sleeper stretch (MSS) and the modified cross-body stretch (MCBS) on posterior shoulder pain and performance measures in amateur badminton players.

Material and Methods. Twenty-two amateur badminton players with posterior shoulder pain were allocated into two groups (n =11 each). Group A received MSS, while Group B performed MCBS. Each group received 3 sessions/week for 4 weeks. Outcome measures including pain, functional disability, internal rotation range of motion, handgrip strength, upper limb power, and coordination were noted at baseline and after 4 weeks of intervention.

Results. Both groups demonstrated statistically significant improvements across all outcome measures (p < 0.001). However, when compared, Group B showed significantly greater improvements than Group A (p < 0.05).

Conclusions. The findings suggest that while both stretching techniques are effective, MCBS may provide superior benefits improving pain and function in amateur badminton players.
