Electromyography is a testing method used to measure the functionality of your muscles individually, between several points – or in comparison (right arm compared to left arm, etc.) It’s a very effective test, but is not a whole lot of fun. The premise is simple. The technician takes a needle. A L.O.N.G. needle – up to 5″ long – and taps it into your skin directly above the muscle they want to test first. Then the tech taps on the top of the needle, causing it to penetrate further and further into the muscle, until the desired reading is obtained. Then – here’s the fun part – then you have to flex this muscle so they can measure the difference between this muscle at rest and in flexion.
Rinse and repeat.
My most recent EMG was to rule out carpal tunnel in my right hand (I could have told them it wasn’t - and I did…) In this case, this test was repeated from the web between my thumb and forefinger, all the way up my arm to the back of my neck – roughly 6-8 testing intersections.
