Vascular Studies screen for blood flow restrictions, including blockages, due to diabetes, high blood pressure, high cholesterol, smoking, obesity, as well as other systemic issues. These restrictions can cause pain and weakness along with peripheral artery disease. It is a non-invasive test of the extremities to calculate the blood flow from the heart utilizing ultrasound examinations and Doppler pressure studies.
A nerve conduction velocity (NCV) screening measures how fast an electrical impulse moves through your nerve. NCV screening allows us to identify any nerve damage.
During the test, nerves are stimulated, usually with electrode patches attached to your skin. Two electrodes are placed on the skin over your nerve. One electrode stimulates your nerve with a very mild electrical impulse. The other electrode records it. The resulting electrical activity is recorded by another electrode. This is repeated for each nerve being tested.
The speed is then calculated by measuring the distance between electrodes and the time it takes for electrical impulses to travel between electrodes.
A related test that may be done is an electromyography (EMG). This measures the electrical activity in your muscles. It is often done at the same time as an NCV. Both tests help find the presence, location and extent of diseases that damage the nerves and muscles.
