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.

Shoulder impingement_TSMShoulder impingement_TSMFor the manipulation intervention, the subjects were in a seated position and a thrust technique was performed. If no cavitation was detected with the manipulation, the thrust was repeated up to 3 times.
Asymptomatic_shamAsymptomatic_shamFor the sham intervention, the subjects were positioned in the same seated position with the therapist holding the patient in the same position as for the thrust manipulation. In this position, the therapist applied all the same forces as done for a thrust-manipulation and held that position for a few seconds, but a thrust was not used.

In this position, the therapist applied all the same forces as done for a thrust-manipulation and held that position for a few seconds, but a thrust was not used.

Primary Outcome Measures
NameTimeMethod
Change in scapular orientation from first to third dayDay 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 Outcome Measures
NameTimeMethod
Change in shoulder function from first to third dayDay 1; Day 2; Day 3

Shoulder function was assessed at the beginning of each data collection day (days 1 to 3) using Disabilities of the Arm, Shoulder and Hand (DASH) and Western Ontario Rotator Cuff Index (WORC) questionnaires.

Change in scapular muscle activity from first to third dayDay 1; Day 2; Day 3

3D scapular kinematic 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.

Change in shoulder pain from first to third dayDay 1; Day 2; Day 3

Shoulder pain 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.
