A physician places a shock-emitting electrode directly over the nerve to be studied, and a recording electrode over the muscles supplied by that nerve. Nerve conduction studies: These tests measure how well individual nerves can send an electrical signal from the spinal cord to the muscles. Imaging studies: The physician may order an X-ray, ultrasound or MRI to check for broken bones, cysts and other masses in the arm. It can confirm the presence of nerve damage and assess its severity. Diagnostic procedures may include:Įlectromyogram (EMG): This test measures the electrical activity of a muscle in response to stimulation, as well as the nature and speed of the conduction of electrical impulses along a nerve.
