Review on American Heritage Industries Contractures Relief by Craig Lovro

I am paralyzed on the left side of my body which causes my arm to be badly cramped before bedtime. I've tried a few different brands, I had high hopes for this one. But after using it every night for 1 month the fabric and straps became slippery and my hand/arm started to slip out of the brace. I tightened them with all my might, but the same thing happened to no avail. The straps seemed to keep my arm and hand in place, but it got worse and worse. And note that due to my disability I can only sleep on my back, so not because I move around in bed a lot. I put my hand on the pillow and at the slightest change in pressure it starts to slip, then I squeeze my hand and can't relax. I don't put on lotion before bed, so it's not that.
