I had a massive stroke 6 years ago and my hand that's paralyzed gripped very tightly as a reflex. I used many braces for trying to keep the pain and spasms. There are SO MANY braces I have used and many more available. None I have encountered had the aspect of holding each finger individually, something that completely prevents my fingers from contracting in any way, when my fingers go to tighten and squeeze with this it only squeezes a stress ball. Ingenious really. If I were to put a ball in my hand without this brace, my knuckles would fold into a position that would ignore the ball. I tried so many things to stop this qnd my fingers were too strong that anything trying to force my knuckles into a solid position it's very painful because my knuckles don't care if something tries to stop it. It will break my fingers out of the force. With the fact each finger is separately held onto a different position on the stress ball prevents my knuckles from curling but the ball pushes back in a non painful Manner. I don't usually feel compelled to write review like this, but it really needs your attention. If you know someone with spastic painful fingers that are paralyzed get them this. I have such relief from constant pain.
