- Abstract
Purpose: The purpose of the present study was to investigate acute effects of muscle energy technique (MET) for the posterior shoulder on glenohumeral joint (GHJ) range of motion (ROM) and isokinetic peak torque values of GHJ rotators. Methods: The study was designed as double blinded randomized controlled trial. 18 male volleyball players volunteered to participate. All participants attended both, muscle energy technique trial for the glenohumeral joint horizontal abductors and sham trial. Pre-intervention and post-intervention internal rotation and external rotation ROM and GHJ rotators isokinetic peak tork values were measured. Repeated measures one-way ANOVA and Bonferroni correction were used for analyzing the differences in the ROM and isokinetic parameters among the trials. Significance was defined as p ≤ 0.05. Results: The experimental group had a significantly greater increase in GHJ internal rotation ROM post intervention compared to control group (p=.005). No significant difference among experimental group and control group were found for external rotation ROM (p>.05). However, a significant increase between the control/experimental and sham trials were found for external rotation ROM post intervention (p=.005). Besides, 60o internal rotator (p=.001) and external rotator (p=.008), and 180o internal rotator (p=.019) and external rotator (p=.049) peak torque values showed significant increase between the experimental and control/sham trials. Conclusions: A single application of an MET for the posterior shoulder provides immediate improvement in GHJ internal rotation ROM and isokinetic peak torque values of both GHJ internal and external rotators in asymptomatic volleyball players.
