5. Study Description
Brief Summary
Interventions including glenohumeral mobilization, sleeper stretches, and thoracic manipulation have been proposed for individuals with loss of shoulder range of motion (ROM). However, the effect of these interventions on shoulder ROM, joint translation, and muscular activity have not been studied in combination.
Detailed Description
Forty individuals with a loss of internal rotation (IR) ROM will be recruited and randomized to one of two interventions at the first session: either posterior glenohumeral mobilization or internal rotation "sleeper" stretching. At the second visit, all participants will undergo a thoracic manipulation (T3-4 segment) followed by a repeat of either the sleeper stretch or glenohumeral mobilization.

Interventional Study Model
Sequential Assignment
Model Description
All participants will undergo a single intervention during the first session, and then combined thoracic manipulation and a repeat of the prior intervention at the second session.
Masking
Outcomes Assessor
Masking Description
Assessment of electromyographic (EMG) activity, IR ROM pre-post intervention, and glenohumeral translation via ultrasound will be performed by a blinded assessor.

8. Arms, Groups, and Interventions
Arm Title
sleeper stretch + thoracic manipulation
Arm Type
Experimental
Arm Description
The group will receive the sleeper stretch at session #1, and a thoracic manipulation followed by the sleeper stretch at session #2.
Arm Title
posterior glenohumeral (PG) mobilization + thoracic manipulation
Arm Type
Experimental
Arm Description
The group will receive a posterior glide mobilization at session #1, and a thoracic manipulation followed by posterior glide mobilization at session #2.
Intervention Type
Other
Intervention Name(s)
posterior glide mobilization
Intervention Description
The participant will be positioned supine on a plinth, with their scapula stabilized against a firm wedge on the table, and the shoulder joint in the resting position (approx. 55 degrees abduction, 30 degrees horizontal adduction, and slight external rotation). With the extremity held in the same position, the researcher will then apply a grade III (into tissue stretch) PG mobilization. This will consist of five 30-second bouts of sustained gr III posterior glide mobilizations.
Intervention Type
Other
Intervention Name(s)
Sleeper stretch
Intervention Description
All participants randomized to the stretching group will perform five 30-second holds of the sleeper stretch. This is performed by lying on the side to be stretched, elevating the upper arm to 90° on the support surface with the elbow bent 90°, then passively internally rotating the shoulder with force provided by with the opposite arm.
Intervention Type
Other
Intervention Name(s)
thoracic manipulation
Intervention Description
Individuals will then undergo a single supine grade V thrust manipulation. All manipulations will take place at the T3-4 segment. If a cavitation ("pop") is not heard or felt by either the subject or examiner, a second thrust will be performed.
