WebThe test can identify the onset of LMN involvement before symptoms are obvious. A common abnormal result in ALS patients is spontaneous electrical activity when the muscle is at rest. A normal EMG result will often result in a diagnosis of primary lateral sclerosis (PLS), but does not rule out the possibility of ALS developing later. WebElectromyography measures the electrical impulses of the muscles at rest and when contracted. Electromyography is usually done with nerve conduction studies. Nerve conduction studies measure how well individual nerves transmit electrical signals to the muscles. Diagnose diseases that damage muscle tissue, nerves or the points where …
