Electrodiagnostic Medicine is the best way that modern medicine has of adequately assessing the function of muscles and nerves. EMG is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph, to produce a record called an electromyogram.
An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, recruitment order or to analyze the biomechanics of human movement. Examinations usually take approximately 20 minutes and there are no restrictions on activity before or after the testing. There are no lasting after affects.
