Hi, welcome to the NeuroTalk Support Groups.

Check out the Myasthenia Gravis Forum

I ran a quick search just using the word "brace" and a lot of older posts came up on the MG forum. It's a fairly quiet forum lately, but there is a lot of older information there that may be helpful. I posted one of the threads below. There were others related to the neck etc.. If you ever need any help with finding things, just post and someone will help you out.

Another thought is asking advice of a physio.

Take care there and please make sure that you talk to your doctor about this issue.
