Table 1 outlines a comprehensive scoring system to assist in the diagnosis and staging of adhesive capsulitis, commonly known as frozen shoulder. The system integrates various factors including comorbidities, clinical evaluation criteria, range of motion measurements, and ultrasound findings. Each parameter is assigned a score that collectively determines the diagnosis: a total score greater than 7 indicates a definitive phase 2 diagnosis (Yes), scores between 6 and 2 suggest an uncertain status (phase 1 or phase 3), and scores less than 2 are indicative of the absence of the condition (No). Negative scores are attributed to conditions that typically rule out adhesive capsulitis, while positive scores reflect characteristics commonly associated with the condition. This scoring approach aims to provide a nuanced assessment, promoting targeted treatment strategies based on the identified phase of adhesive capsulitis
