Final answer:
Pain, swelling, and decreased range of motion in the shoulder joint may indicate a shoulder injury. Inflammation and scar tissue formation can limit shoulder mobility. Physical therapy can help improve range of motion and function of the shoulder joint.
Step-by-step explanation:
Pain and swelling over the clavicle with decreased range of motion in the shoulder joint may indicate a shoulder injury. Inflammation and scar tissue formation due to an injury can lead to adhesive capsulitis, also known as a 'frozen shoulder,' which can limit shoulder mobility.
Common causes of shoulder injuries include repetitive use of the upper limb in activities like throwing, swimming, or racquet sports, which can result in inflammation, tears, or degeneration of the bursa, tendons, or rotator cuff in the shoulder joint.
To assess the functionality of the shoulder joint, a physical therapist may perform range of motion tests that involve abduction, adduction, circumduction, flexion, and extension of the arm.
Treatment for shoulder injuries may involve physical therapy, which includes applying heat and ice, performing exercises, and gradually improving range of motion and function of the shoulder joint.
