I am not fully recovered yet–my accident happened early September. But I am feeling much, much better. And like you love hearing “success” stories of people who are back riding after these injuries. There are lots of them–go to a horse show or a busy barn with your brace on and you’ll make tons of new friends . . .
Anyway, for me, it was helpful to think about the demands of my life and ask the Dr directly about them. So, for work I needed to drive 25 minutes each way, and sit in an office chair for 8 hours. To fully take care of the horses, I needed to be able to lift 50 lb feed bags and hay bales, push a wheelbarrow, lead the horses, etc.
For the first 6 weeks I had to wear the brace whenever I was up. I was encouraged to wear it sleeping too, but had trouble with that. I could not put it on myself. For the first 2-3 weeks of that I was in too much pain to try to do anything at all. It hurt to sit in my chair, it hurt to lie in bed. I alternated between the 2, very unhappily. I broke some ribs, too, though, and I think it was those and not the spine that hurt so much.
After that I walked around a little more (in and around the house, even short walks toward the end). I also rode in the car a few times.
I was completely off work for 2 weeks, then started work back from home, at 4 weeks went back. (My Dr wanted me to be completely off for 6 weeks but that was not possible for my job)
After the brace came off I was able to take care of the horses day to day–feed them, lead them in and out, but I still am not supposed to do the hay/feed bags myself.
I am lucky not to live alone, so I didn’t have to drive, carry groceries, etc though I did have to hire some help with the horses. FWIW I did not feel like I lost much core strength in the brace. My biggest PT challenge has been my neck which is very stiff after the accident/brace. But the lifting and core exercises are pretty easy.
I wish you luck with your Dr and recovery. If you are in the DC/NoVA area feel free to PM me and I can tell you who I have been seeing.
