Hi all - I had l5/s1 fusion with rods in December. Sitting at work has been a challenge, so I tried wearing my brace during work hours and it's made a huge difference. I'm not as sore at the end of the day and my posture is better. I'm not sure if they recommend it or not, but it does help. I'm 52 and do my PT exercises, but this was my game changer. According to dr., I'm doing well and fusing, so I don't see how this can hurt.
