Medical Tests A variety of methods may be used to diagnose<unk> . The health practitioner may examine the shoulder for muscle atrophy of the deltoid muscle. Furthermore, a patient can also be tested for weakness when asked to raise the arm. The deltoid extension lag sign test is one way to evaluate the severity of the muscle weakness. During this test, the physician stands behind the patient and uses the patient's wrist to elevate the arm. Then, the patient is told to hold this position without the doctor's assistance. If the patient cannot hold this position on their own and an angular drop occurs, the angular lag is observed as an indicator of<unk> . When the shoulder is at its maximum extension, only the posterior area of the deltoid muscle and the axillary nerve are working to raise the arm. Therefore, no other muscles can provide compensation, which allows the test to be an accurate measure of the axillary nerve’s dysfunction. Additional testing includes electromyography (EMG) and nerve conduction tests. However, these should not be done right after the injury because results will be normal. These tests must be executed weeks after the initial injury and onset of symptoms. An MRI (magnetic resonance imaging) or X-Ray may also be done by a doctor.
