Iron Crush Hand Grippers, $14.99 on Amazon: http://amzn.to/2sRArGY
My occupational therapist doesn’t like these. She said that there was a danger that they would make my grip even stronger, which is not what I need right now because I have a problem with spasticity. However, I have found just the opposite to be true. When I can’t get my hand to relax due to spasticity, I do a bunch of squeezing reps until my gripping muscles fatigue. After a couple of dozen repetitions, the spasticity goes away and I can work on my other hand muscles, like extensors muscles and those used for picking up objects.
It comes in three different grip strengths; 30, 40 & 50 lbs. I can only manage the 30 lb on my weak affected side, but I use the 40 & 50 pound to work out my unaffected side simultaneously. My therapist tells me that by doing my exercises on both sides of my body simultaneously, some of the brain signal (as much as 15%) gets through to the affected side as well.
Why did I pick this particular item when there are several other similar and slightly cheaper products? Because of the 2-year money-back warranty. They must have confidence that the product will not crack or split during that period. Mine are going on 2 years old now, and they are good as new despite daily use.
