EMG NCV Testing

EMG & NCV tests assess muscle & nerve function, aiding diagnosis & treatment.

Electromyography (EMG) and nerve conduction velocity (NCV) testing are diagnostic procedures commonly used to evaluate the health and function of muscles and nerves. During an EMG test, small needles are inserted into specific muscles to record their electrical activity at rest and during contraction. This helps identify any abnormalities in muscle function, such as weakness or spasticity, and can aid in diagnosing conditions such as neuropathy, myopathy, or radiculopathy.

NCV testing, on the other hand, measures the speed at which electrical impulses travel along nerves. Electrodes are placed on the skin overlying the nerves, and small electrical impulses are applied to stimulate the nerves. The time it takes for the impulses to travel between electrodes is recorded, providing information about the integrity and function of the nerves. NCV testing can help diagnose conditions such as carpal tunnel syndrome, peripheral neuropathy, and nerve compression or injury.

Together, EMG and NCV testing provide valuable information to healthcare providers about the health and function of the neuromuscular system. These tests are often used in conjunction to help diagnose a variety of neurological and musculoskeletal conditions, guide treatment decisions, and monitor disease progression. They are typically performed by neurologists, physiatrists, or trained technicians in specialized medical facilities.
