The following conditions can be detected with a nerve conduction velocity test: Because low body temperatures impair nerve conduction, a normal body temperature must be ensured for the nerve conduction velocity test. The nerve conduction velocity test can be used to diagnose actual nerve problems such as peripheral neuropathy and mononeuritis multiplex, as well as cases where nerves have been compressed mechanically. Numbness, burning sensations, or tingling are some of the symptoms that may trigger a health care expert to perform a nerve conduction velocity test. Electromyography is used to rule out or discover muscle disorders that may be present as a result of muscular or neurological disease.ĭoes persistent twitching in the calf indicate severe neurological condition? Why Is a Nerve Conduction Velocity Test Performed?

A nerve conduction velocity test is frequently performed in conjunction with an electromyography (EMG). Nerve disorders or increased stress on the nerve might cause a decrease in transmission speed. Speed of impulse transmission is calculated using the distance between the electrodes and the time taken for electrical impulses to pass between electrodes. The other electrodes record the electrical activity that results due to nerve stimuli. With a very small electrical impulse, one electrode activates the nerve. Surface patch electrodes similar to those used in an electrocardiogram are commonly utilized, and they are put on the skin surface over the nerve in various areas. The nerve is stimulated electrically, and the electrical impulse which goes downstream from the stimulus is assessed in this test. How Is the Nerve Conduction Velocity Test Performed? It is crucial to make these distinctions in order to get an accurate diagnosis and plan the patient's therapy. It can also assist the doctor in distinguishing between a neural disorder and a disorder in which the muscles have been damaged by a nerve injury. The nerve conduction velocity test helps the doctor distinguish between a nerve fiber injury and a myelin sheath injury, which is the protective coating that surrounds the nerve. Nerves that are healthy send electrical messages faster and with more strength than nerves that are injured.

These nerves allow one to regulate their muscles and detect their surroundings. The area where the nerve root exits the spinal cord is the area where the peripheral nerves begin.

The neurologist can evaluate if any nerve injury has occurred, where it has happened, and to what extent based on the results produced after the test. What Is the Nerve Conduction Velocity Test?Ī nerve conduction velocity test measures the velocity of electrical impulses as they travel through the nerves in the body.
