description | Background: Posterior capsule tightness (PCT), commonly seen in overhead athletes, is a
soft tissue adaptation that is also noted in non-throwers. PCT is associated with scapular and
humeral kinematic alterations, significant restriction of shoulder internal rotation (IR) range of
motion (ROM), and significant scapular anterior tilting. Sleeper and cross-body stretches (CBS)
are suggested for PCT and IR deficits, and have been modified since introduction. A novel
modified sleeper stretch (NMSS) was designed in this study to prevent the risk of anterior
translation of the humeral head. Though the effects of posterior shoulder stretching exercise
have been widely studies, to the best of our knowledge, no previous studies have investigated
the effectiveness of posterior shoulder exercises in decreasing scapular anterior tilting.
Objects: To compare the immediate effects of two posterior shoulder stretching exercises
(NMSS and CBS) on scapular anterior tilting and shoulder IR ROM.
Methods: Thirty-two subjects with anteriorly tilted scapula and IR deficits [mean age: 24.3
± 2.5 years; 15 males and 17 females] participated in this study. Subjects were randomly
assigned to either the NMSS or CBS groups. Scapular anterior tilting (at rest and at shoulder
60° active IR) and shoulder IR ROM were measured before and immediately after intervention.
Results: Scapular anterior tilting significantly decreased, while the shoulder IR ROM significantly
increased in both groups. However, there was no significant group-by-time interaction
effect or significant difference between the groups.
Conclusion: Both stretching exercises were effective in restoring shoulder IR ROM and decreasing
scapular anterior tilting. |
