Gait re-education programmes

Hello

I have been going through the journey of trying to fix what I suspect is CECS via private healthcare in the UK. I am going through insurance, so first had to go through their online physio people with them. Finally I managed to get referred to see a sports medicine consultant at hospital. He has done an MRI to rule out other stuff, which was normal, and is now pretty confident it's CECS. He said before compartment testing and surgery (if required) he first recommends doing a gait re-education programme with physiotherapy. He said these are very successful and many patients need not have surgery. Does anyone have any experience of these programmes? Did they work for anyone? He said if it doesn't work, he can still refer me to the surgeon so I am going to try it out, but would love to hear some thoughts.

Thanks!
