My father is 89 and has post-polio syndrome. He had polio in his 20s, recovered well and led an active adult life (tennis and skiing) but since his 60s, he's been getting weaker and weaker. His legs are very weak now and he's falling down more and more. He lives in an independent living retirement home in 2-bedroom apartment with my mother. He uses a walker which is sort of a combo as it has a seat he can sit in once he uses it to as a walker to get somewhere but he still tries to walk and he has little strength. And what he has is not a self-propel wheel chair, it's more walker than wheel chair.... I wonder what you'd recommend in terms of transitioning him to something that was self-propelling but had the option of being used as a walker... Also, what kind of person could help him make this transition.. An occupational therapist? They live in a small city of 24,000 that has limited resources.. Appreciate any thoughts you have.
