9. Diagnostic and Management Tests

Several tests help with preliminary diagnosis and disease management. An electromyogram or EM measures electrical activity in muscle cells. Nerve conduction studies measure how fast nerves transmit impulses. An electrocardiogram or ECG shows a graphic representation of heartbeats as electrical activity and patterns. An echocardiogram records the motion of the heart muscle. Doctors can view images of the brain and spinal cord using MRI or CT scans.
