This device works surprisingly well. It actually stimulates muscles causing them to contract and relax.I had fusion surgery on my neck following a collision where I was struck at 35 to 40 mph from behind by another driver while sitting at a stop light.  After the fusion failed, they discovered a pinched nerve that goes from my neck down my left arm.  I continue to have muscle spasm from this and I find that turning this up to a high level on one of the &#34;pulse&#34; setting such as message, manipulation or acupuncture does relax the neck and cause nearby muscles to relax as well. It beats taking muscle relaxers!  It doesn't respond well to jewelry so I would advise taking any necklaces off before use. Maybe they can come up with one that covers the shoulders too?
