I have had 7 major spine surgeries for congenital spinal stenosis and two major fracture dislocations of L3 and L2. Now fused from T9 to S2 and using a body brace. In my right leg, there is no sensation, no proprioception and loss of quad and hip flexion power. I was able to walk using Activator poles for 3 hours per day at 14 months post op. With a body brace leaning over a walker or to one side with a cane doesn't make sense. The upright posture and off loading with poles is also better for hip and knee OA and ankle injuries.
