I completely agree my mother has MS and I have my own autoimmune issues. Something like this would be extremely helpful for people with debilitating diseases that cause muscle deterioration.

Maybe you can checkout the Dephy Exoboot: https://www.dephy.com No idea how far along they are though, but looks like they are open for early access.

I'm sure you've already seen https://eu.hypershell.tech

I'm hopeful these get cheaper, smaller and lighter, and more powerful. Would be great to have these accessible to a lot of people.

Wow, that's awful. Have you looked into the existing powered exoskeletons? Or are those too hip/thigh focused to help?

Are you using something like this? Do you get back most of your previous functionality?
