Electromyography (EMG) is a diagnostic test that measures the electrical activity of muscles. We use it to evaluate muscle and nerve problems, such as muscle weakness, muscle twitching, and nerve damage.EMG is performed by placing surface electrodes on the skin over the muscle or inserting a thin needle electrode into a muscle. The electrodes detect the electrical signals produced by the muscle when it contracts or relaxes, and these signals are then displayed on a computer screen as a series of waves or spikes. The pattern of the electrical signals provides information about the health and function of the muscle and the nerve that
controls it.
We perform EMG in both outpatient and in-patient settings, and it is generally a safe and well-tolerated procedure. The results of the EMG can help us guide further medical evaluation and treatment for the underlying condition.In combination with nerve conduction studies, EMG can provide a comprehensive evaluation of nerve and muscle function, and is a valuable tool for diagnosing a variety of conditions, such as peripheral neuropathy, myasthenia gravis, and motor neuron diseases.
