This family wanted the support of thermoplastic splint with the comfort of neoprene, so I combined both.
I made the custom splint in a traditional manner by tracing her hand, melting aquaplast, and forming it to her hand. I left the forearm trough as a plastic stay to keep the wrist straight.
I measured her forearm for the neoprene and sewed straps and d-rings to it. I attached the neoprene to the aquaplast with rivets because I thought it would be the most secure option. I lined the inside with padding to make it nice and comfortable.
I used 1/16″ aquaplast and there is a little give to them. I find a slight dynamic component is so important. The client tolerates them well and is maintaining her range of motion.
