* Bonferroni correction p < 0.005 for within-group differences.
† Bonferroni correction p < 0.005 for time factor. EBG: elastic band exercise group; EB-DOG: elastic band plus double oscillation exercise group; H-ABD: horizontal abduction; H-ADD: horizontal adduction; ER: external rotation; IR: internal rotation.
