How is radial tunnel syndrome diagnosed?
Pain in the forearm and hand are usually the symptoms that send a person to the doctor. However, there are no tests to prove a person has radial tunnel syndrome. This makes the diagnosis difficult. The doctor must depend on the patient’s physical exam and the type and location of the pain. As part of the exam, the patient is asked to turn his or her palm up with a straight elbow while the doctor restricts arm and hand movement. If the patient feels pain while trying to move the arm or hands against resistance; it is a sign of radial tunnel syndrome. In another test, the patient is asked to point with his or her middle finger against resistance. Pain with this movement is another sign of radial tunnel syndrome.
