Electromyography
Electromyography, commonly known as EMG, is an advanced diagnostic test that measures the electrical activity of muscles and the nerves that control them. It is used to identify the source of muscle weakness, pain, numbness, tingling, or other symptoms that may be related to nerve or muscle dysfunction.
Arlington PT is one of the few physical therapy clinics in the Arlington and DFW area to offer EMG testing in-house, allowing our team to gather critical diagnostic information and apply it directly to your treatment plan without the need for an additional specialist referral.

How EMG Works
An EMG test typically involves two components:
Nerve Conduction Study (NCS)
Small electrodes are placed on the skin over specific muscles and nerves. A mild electrical impulse is delivered to measure how quickly and effectively the nerve signals travel. This helps identify areas of nerve damage or compression.
Needle EMG
A small, thin needle electrode is inserted into specific muscles to measure their electrical activity at rest and during contraction. This helps identify whether the muscle itself or the nerve supplying it is the source of the problem.
