Returning to work

I'm wondering if anyone has successfully gone back to work in a physically demanding job after they have found a treatment that would allow them to return to work? Did you return to work in your previous job or were you accommodated in a less physical job?

What procedures did you go through to return to work? Was there a Physical Demands Analysis? Did you work with an occupational therapist to see what you could and couldn't do?

Thank you,
