WebbNerve conduction velocity between 50 to 60 meters per second is considered normal. A damaged nerve may send a slower and weaker signal than a healthy one. It is possible … WebbA nerve conduction velocity (NCV) test measures how fast an electrical impulse moves through your nerve. NCV can identify nerve damage. This test is also called a nerve conduction study (NCS). During the test, your …
WebbSensory nerve conduction studies usually demonstrate normal or slightly reduced amplitudes. 7, 522, 939, 1087, 1192 Sensory nerve conduction velocities are normal or only mildly slow. Motor nerve conduction studies demonstrate that the distal motor latencies are prolonged by about 10–30% above the upper limit of normal and that conduction …
