Effects of postural restoration therapy compared to traditional therapy on internal rotation in collegiate overhead athletes.
Glenohumeral internal rotation deficit (GIRD) is a condition characterized by a decrease in internal rotation when compared bilaterally (Lintner, Mayol. Uzodinma, Jones, Labossiere, 2007). The purpose of this study was to evaluate the efficacy of differing rehabilitation programs on internal rotation in athletes who commonly present with Glenohumeral Internal Rotation Deficit. Participants were randomly assigned to a treatment group, Postural Restoration or Thrower’s Ten and Sleeper Stretch, and asked to perform the respective rehabilitation program three times a week, at home. Glenohumeral internal rotation was measured prior to beginning the exercise protocol as well as, once a week for four weeks following the initiation of exercises. There were no statistically significant differences between the two groups in how they affect glenohumeral internal rotation. It cannot be concluded that the groups are different across time, between groups, or that there is an interaction between the two groups.
