The diagnosis of a frozen shoulder usually involves a physical examination and imaging tests such as X-rays and MRI. During the physical examination, your doctor may look for signs of pain, restricted movement, and tenderness around the shoulder joint.
Diagnostic Imaging Tests
X-Rays: X-rays of the shoulder can help your doctor identify any structural abnormalities or signs of degeneration.
MRI: Magnetic resonance imaging (MRI) is a type of imaging that uses radio waves and a strong magnet to create detailed images of the soft tissues in the shoulder, such as the muscles, tendons, and ligaments. It can also detect bone spurs, fluid buildup, and other signs of frozen shoulder.
Tests for Pain and Range of Motion
A doctor may also use tests to measure the range of motion in the shoulder, as well as the degree of pain. These tests help the doctor assess the severity of the condition and determine the best course of treatment.
Shoulder Abduction Test: This test measures the ability of the shoulder to raise the arm out to the side. To perform the test, the doctor will ask the patient to lift their arm out to the side while the doctor monitors the amount of pain and range of motion.
Flexion Test: This test measures the ability of the shoulder to bend forward. The doctor will ask the patient to bend their elbow and bring their hand up to their shoulder. The doctor will then measure the amount of pain and range of motion.
Internal Rotation Test: This test measures the ability of the shoulder to rotate internally. To perform the test, the doctor will ask the patient to rotate their arm inward while the doctor monitors the amount of pain and range of motion.
External Rotation Test: This test measures the ability of the shoulder to rotate externally. The doctor will ask the patient to rotate their arm outward while the doctor monitors the amount of pain and range of motion.
The results of these tests can help diagnose a frozen shoulder and help the doctor determine the best course of treatment.
