@Gramma,
I am predominently motor in both legs with my right calf getting noticably smaller than my left from not using it. I also have foot drop on the right. I saw a physical therapist for eval last week and will start regular sessions. She told me I needed stretching and strength building. We all are different, so what is prescribed for me, may not be right for you. At home I am going to be using the pedals that are not attached to a bike to help build up my leg strength. Some models allow for both arms and legs. I was assisting my legs by lifting the into the car, onto the bed, putting on slacks etc which is not good. So I am making them work. I also stretch my calves using a towel around my foot and pulling back. I have large exercise elastics to work on my toes and feet with resistance. I had to get off my butt!

I have to wear my AFO braces all the time during the day, but I find now that the reduced fatigue I have from them allows me to be more mobile and do more. Water exercise was recommended and we have an above the ground pool but I cannot negotiate the ladder to get in. I am thinking of the town pool, maybe you have one in your area you can use. Us seniors (I am 63) get lots of extras here.

My balance is off also and I am better with the brace, but I have to use a cane to help me steady myself. I will be getting gait training in my PT. What was advised to me was not to over do it and increase gradually.
