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).Function was measured with the Constant- Murley score,2,38 which ranges from 0 to 100 and includes subscales for subjective pain (0-15 points), everyday activities (0-20 points), and objective subscales on mobility (40 points) and strength (25 points), with higher scores indicating greater functionality. The Constant-Murley score has been shown to have good reliability13,55 and is one of the most frequently used measures in clinics.13,55
