Final answer:
To diagnose frozen shoulder syndrome, a physical therapist will test the range of motion and create a physical therapy plan.
Step-by-step explanation:
To diagnose frozen shoulder syndrome (adhesive capsulitis), a physical therapist would assess the functionality of the joint by testing the range of motion. They would ask the patient to perform movements like abduction, adduction, circumduction, and flexion and extension of the arm. Based on the assessment and the symptoms, the physical therapist would create an appropriate physical therapy plan, which may include exercises, heat packs, ice packs, and gradually increasing physical activity as the injury heals.
