Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Primary purpose: PREVENTION

Brief summary: The purpose of this study is to determine if stabilizing the scapula (shoulder blade) during a common shoulder stretch is more effective at improving shoulder range of motion than not stabilizing the scapula. Investigators hypothesize that scapular stabilization during horizontal adduction stretching will demonstrate greater gains in shoulder range of motion than stretching without scapular stabilization.


Eligibility criteria: Inclusion Criteria:

* athletes with at least two years of volleyball experience
* athletes with no current shoulder pain
* athletes between the ages of 15 and 21
* athletes with a 10 degree or greater difference in internal rotation between shoulders

Exclusion Criteria:

* athletes currently experiencing shoulder pain
* athletes having less than two years of volleyball experience
* athletes not meting inclusion criteria

Primary outcomes:
measure: Change in Posterior Shoulder Tightness
timeFrame: Change from baseline posterior shoulder tightness to immediately following manual stretching. The baseline is measured, followed by 3 stretches held for 25 seconds and then the follow up measure is taken. This is the conclusion of this measure.
Secondary outcomes:
measure: Change in Internal Rotation
timeFrame: Change from baseline internal rotation to immediately following manual stretching. The baseline is measured, followed by 3 stretches held for 25 seconds and then the follow up measure is taken. This is the conclusion of this measure.
