Adding a third stimulation site to the two normally used increased the sensitivity of the test from 80 to 96 percent. In one study, researchers used the NCV test to examine damage to the ulnar nerve, which provides sensation to the hands. The test is done along the path of the nerves on an arm or a leg, depending on the condition being investigated. Your doctor may want to perform the test in more than one location. The sensation may be uncomfortable, but it typically isn’t painful. If all limbs are tested, then it will be more than 1 hour. The entire test takes 20 to 30 minutes on one limb. One common test, for example, stimulates nerves in the finger and records the stimulus with two or more electrodes near the wrist. The nerve will be stimulated by a mild and brief electrical shock from the stimulating electrode.They may use a jelly or some kind of paste to help the electrode stick to the skin.
Your doctor will place two electrodes on your skin, one that stimulates the nerve and one that records the stimulation.Your doctor will find the nerve to be tested.You may need to remove some clothing and wear a gown.You’ll be asked to remove any metal objects, such as jewelry, that could interfere with the procedure.But it was worth it to get my diagnosis and start medication (for bfs and willis ekbom).The particulars of nerve conduction studies can vary, but they follow the same general process: It flared up my trigger toe also (tendonitis). I took a lot of warm epsom salts baths and used heating pads to calm the muscles down. Even having falls becuase of the jerking muscles in my legs and lower back.
But at that point I was having trouble walking some times before the test. The lower body one I had trouble walking for a few days after becuase of spasms, jerking, and cramps. It also confirmed the carpal tunnel diagnosis I had gotten a decade before. I almost had an accident driving home from the upper body one, my left arm suddenly jerked to the outside, keep both hands on the wheel at all times if you get jerks in your arms. It made my spasms, twitching, cramps, and especially the myoclonic jerks worse. If you've ever accidentally touched the metal part of a plug while pulling it out, that's the feeling. A lot of it I didn't feel as pain, but like a current feeling. It wasn't painful during most of the testing. Emg doesn't just test for als if that's what you are concerned you have (and you probably don't have that).
