There may be weakness of wrist and hand flexion and difficulty moving the fingers. Severe cases may display wasting of the hand muscles, or a characteristic "claw-like" deformity. A detailed history may be needed to determine the possible cause of the neuropathy. Tests that reveal ulnar nerve dysfunction may include an EMG (a recording of electrical activity in muscles) and nerve conduction tests. Testing is guided by the suspected cause of the dysfunction, which in turn is suggested by the history, symptoms, and pattern of symptom development. Tests may include various blood tests, x-rays, scans, or other tests and procedures.
