spina bifida research proposal

Hello all,

I am currently trying to research ideas for my research proposal. one idea im thinking of is to do with shoulder pain/ rotator cuff injury in spina bifida/ long term manual wheelchair users. i would really appreciate peoples opinion on what they think of this as a topic. i have done a brief(!) lit review on it this evening, and there does not seem to be a lot of research out there, especially in relation to spina bifida patients. i am not sure how i will focus in on this topic, but maybe something along the lines of "incidence of shoulder pain/ RC injury in SB patients," or " profile of SB patients with shoulder pain/ requirung shoulder surgery". very basic i know but you get the idea.
Advice appreciated please!!:)
