I'm new to this site and have some questions about recovery in regards to range of motion. I'm about 6 weeks post-op. Had a 2-level TLIF (L4-S1) after 2 failed discectomies. Recovery is going well, no back or leg pain. I just have minor soreness once in a while. A lot of walking and physical therapy seems to be helping. I noticed after the surgery my flexibility was pretty much shot. My main concern is range of motion. How long until I see improvements in that area? Range of motion and being able to perform my duties in the military is a big concern for me. I still can't tie my shoes but seems to be getting better everyday. I just started using a bone stimulator last week to help with the fusion process, mainly because I'm a light smoker. My doctor advised me not to bend or twist, but for how long? Any advise or recommendation in regards to recovery would be greatly appreciated....yes I know, stop smoking is one advise.
