Sue - That is why I specfcally mentioned CT when referring to the CT brace: 'A specific C.T. wrist brace' - or, if you like: 'A brace 'specific' to CT' *for CT. Yes, better to be more specific 'smile'.
Mind you, I did not find any impediment to blood flow whilst wearing the brace. The brace keeps the hand in neutral - which is what it is meant to do - thereby 'not' impeding blood flow. Stops one bending the hand, clenching fist, curling fingers etc etc. A 'neutral' hand, blood flow not impeded. Must not pull the fastenings too tight of course...just comfortable just secure. Think people might have a tendency to over-tighten the fastenings!
Hope you can sort the problem Mathie -
Oh yes. Can also be elbows at fault. IF you have a trapped ulnar nerve then can also have hand problems - I also have entrapped ulnar nerves (both elbows) with osteophytes. Great - don't weaken! <LOL>
