If a claimant can achieve a WCA activity by licking his fingers first, I think in all probabilities he will not score points. Nevertheless, I would still put forward the difficulty faced.
I certainly could not say if he should be put in the support group. It's not possible to apply the WCA to somebody through a forum, and in any case, it would only be opinion.
My opinion on this would be, if he can manage to turn the pages only at the cost of pain for instance he could be classed as not being able to.
But, if he can sucessfully turn a page by first liking his fingers to do and not cause himself actual pain in doing this, then he would be classed as being able to turn the page.
