What to Expect with EMG Testing. The doctor performing your EMG test will briefly discuss your symptoms and examine your strength, reflexes and sensation .

An electromyography (EMG) is used to help diagnose nerve or muscle disorders. Electrodiagnostic exams typically consist of two distinct tests: a needle electromyogram to assess nerve activity within the muscles, and a nerve conduction study that evaluates the motor neurons controlling muscle movement. The nerve conduction study is usually the first portion of the EMG, and uses small sensors on the surface of the skin. Electromyograms (also known as EMGs) are tests to help distinguish whether muscle weakness is purely muscular or neuromuscular in nature. In an EMG, a needle electrode is inserted into the muscle to measure the electrical activity of muscles. Both procedures are considered non-invasive and carry very little risk associated with them.
