How much walking do you do, Geo.? While the suggestion given prairie ghost may also have some application, I cannot imagine that slowly increased amounts of walking, eventually in uneven ground, and even in some ground cover, wouldn't help some.

My Grandad had a stroke in his mid 70s, leaving him with limited usefulness on one side. He was a very determined man and exercised and walked until he got back so much of his lost function that you couldn't tell it had ever happened.

All cases are different, but walking a lot is great for many aspects of our health and well being. Walking a mile around fields on the uneven end rows, etc. carrying a gun might even better in your case than walking 4 miles of sidewalks.

May God bless America and those who defend her.
