If you can't find one in your area, Dr. Subrarmanian at Hershey Medical Center in Hershey is on the list for post polio consultations. I have had to wait 5 months to see him having gotten a referral from my neurologist. You would have to get a referral to him. The contact is Penn State Neuroscience Institute 717-531-3828. I was 10 months old when I had complete paralysis except I could move my eyes. PT does not seem to help, I do take water exercise twice a week in deep water and had been a good lap swimmer for years plus yoga until hip replacements and broken wrists precluded continuing. I have been through multiple attempts to get a brace for my left leg with nothing satisfactory. My left foot is in collapse and the orthopedist said "you would not like me very much if I operated on that foot". I understand the recovery period is extensive with no assurance of success. I will take my chances at age 73.
I think you have to know your body and find a good physiatrist if you can locate one and persist in getting answers. That may be ideal in the absence of locating a post polio specialist. They are very rare.
I spelled the doctor's name incorrectly it is Thyagarajan Subramanian, MD.
