My left hand likes to curl as well, but I straighten my hand (I hold it down & strap it- w/the 2 Velcro strips that are attached to my chair, 1 at the wrist & one at the knuckles) everytime I get in my chair.
Let me explain: years ago, my “paralyzed” (my hand feels stuff, but it can’t move voluntarily) left hand was annoying me, so as a joke, mk strapped it down. but I loved it, so I always do it now! It’s probably bad that I can’t use it’ but ii has it’s pros & cons, & for me, the pros outweigh that 1 con!
Then when I was getting my permobile w/c, the sales guy saw my Velcro strap, & said he could put a permanent one on my new w/c, cuz the w/c company sells these Velcro straps that attach to the chair (though thx goodness my mom sews so well & was able to switch to some heavy duty Velcro, cuz I put a LOT of strain on these little straps!)
Anyway, here’s my pros for using a Velcro strap on my ?paralyzed? hand::
1. It’s such a headache having to constantly guard my left hand everytime I laugh & sneeze (cuz my arm contracts into my body, & falls off the armrest)!
2. It does allow me to use what left side strength I have (think in the left shoulder). With it, I can straighten my arms to lift my butt & move it right, forward, & back. But w/o it, my hand falls off of the armrest, so I don’t have the leverage to lift myself!
3. It also allows me to lean forward (say to scratch my foot) & “catch myself” so I don’t fall out of my chair.
