Here is a link to one with an arm flap! This brand has several styles and should give you a good idea of what to look for. I think this is one of the brands my orthotist gave me when I started out. Initially it’s definitely a learning curve but eventually she’ll figure out what works for her and what doesn’t. And feel free to PM if you have other little questions. I was braced for five years and am happy to offer what advice I can.
