Web4 jul. 2024 · A nerve conduction velocity (NCV) test — also called a nerve conduction study (NCS) — measures how fast an electrical impulse moves through your nerve. NCV can identify nerve damage. During the test, your nerve is stimulated, usually with electrode patches attached to your skin. How does the H-reflex work?

WebStandard H reflex conduction studies were followed by monopolar needle stimulation of the first sacral spinal nerve. The ratio of the spinal nerve latency to the H reflex latency (S1 ratio) was calculated. The abnormal S1 ratio seen in 77% of the subjects suggested relative slowing within the spinal segment of the nerve.
