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.

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.

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?
