Anyone tried taping to stop hyperextension, instead of expensive oval-8 or murphy ring splints?

[rowantree]

both my thumbs PIP joint (nearest nail) hyperextend a lot and are painful all the time. I looked at murphy ring splints and oval-8 splints but they're so expensive. I could wait to get some from surgeon or physio but to be honest it would take soo long! Anyone managed to find cheap splints or good taping techniques that help? What kind of tape? KT tape? Thanks
