Jake, I also came out of a coma. I believe the brain continues to learn. At first I was in a wheel chair. Walking was impossible with my imbalance. I kept doing exercises and slowly progressed to where now I can walk on even surfaces without any device. For the grass and gravel outdoors I use a quad cane. Have you used physical therapy? It was a great help to me. I tried both home health for physical therapy only and then out patient services. The latter provided more exercises with the equipment available. At each session I began with their stationary bicycle for 10 minutes. I did a weekly session through PT outpatient to continue what I learned at home(otherwise PT was too expensive under Medicare- 80% coverage). At home I use a mini cycle machine everyday. I provide my own chair to cycle with the machine. I believe it is important to strengthen the core and limb muscles to prevent any falls. In the last few weeks diet and routine exercises have made a significant improvement for me. I will continue to increase my exercise duration. The brain can’t learn if it is not challenged. It is never too late. Toni
