Study Overview
Brief Summary
The hypothesis of this study is that thoracic spine manipulation would reduce pain in subjects with SIS and cause changes in scapular kinematics and muscle activity in subjects with impingement symptoms and in asymptomatic subjects. With this study, the investigators want to answer if possible changes in scapular motion and muscle activity following a TSM depend on the symptoms or if it is generic to individuals without shoulder dysfunction and not specific to subjects with shoulder impingement.
Detailed Description
Subjects with shoulder impingement signs will be evaluated and will be compared with subjects asymptomatic for shoulder symptoms. Both subjects will be randomly assigned to one of two intervention groups: thoracic spinal manipulation (TSM) or sham intervention. We want to know if possible changes in scapular motion and muscle activity following a TSM depend on the symptoms or if it is generic to everyone. Also, we want to know if TSM reduces shoulder pain immediately and in a short-therm period.

Outcomes
Primary Outcomes
Change in scapular orientation from first to third day
Time Frame: Day 1; day 2; day 3
3D scapular kinematic (upward/downward rotation; internal/external rotation; anterior/posterior tilt) was assessed pre- and-post thoracic spinal manipulation and sham interventions at first and second days. At the third day of evaluation the measure was assessed only once.
Secondary Outcomes
- Change in shoulder function from first to third day(Day 1; Day 2; Day 3)
- Change in scapular muscle activity from first to third day(Day 1; Day 2; Day 3)
- Change in shoulder pain from first to third day(Day 1; Day 2; Day 3)
