Secondary Outcome Variables Secondary outcome variables were joint rangeof- motion limitations, Constant-Murley score for pain and function, and number of active MTrPs. Active articular limitation of the glenohumeral joint was measured in degrees, using a digital inclinometer (Acumar Digital Inclinometer; Lafayette Instrument Company, Lafayette, IN) for flexion and abduction motion. For internal and external rotation, a subscale of the functional Constant- Murley score was used to determine rotation based on functional movement (APPENDIX A).
