Failure at hand resting on leg

When I drive one of the positions I try to do is rest my open palm on my left leg.

Multiple failure points:

1. Bicep spasticity puls arm off of leg.

1. 4 finger spasticity requires all my strength in my good hand to straighten. Dangerous while driving.

1. Thumb spasticity is not possible to control at the same time as straightening the fingers.

1. Wrist spasticity curls the wrist off the leg almost immediately.

In summer this sometimes works.

I expect that every stroke doctor and therapist in the world should have a protocol, not a guideline, to correct these problems. There are hundreds of thousands of stroke survivors every year needing these solutions and I bet your doctor has not done ONE DAMN THING to address any of those problems.  I don't care how hard it is to solve, at least try something.
