The objective of the proposed study is to assess how myofascial massage alters stiffness and microvascular perfusion of shoulder muscles and how these changes are influenced by patient-therapist interactions.

The primary hypothesis is that stiffness of shoulder muscles will be decreased, and microvascular perfusion will be increased after a 30-minute myofascial massage, and that the addition of patient-therapist communication levels will result in greater changes with certain levels.

Please note that there are certain details left off of this registration in order to collect information regarding certain aspects of the trial. These details (approved by the IRB) will be updated at the end of the trial.
