Tünde Szarka has posted some photos on her Facebook page showing her work with children in Nigeria.
Tunde has been to the Cerebral Palsy Center in Lagos before, but as far as I am aware this is the only such work in that part of Africa. Practice has been ongoing for some time in South Africa at the Sizanani Children’s Home but I do not know of any other.
