Descripción: This physical therapist is assisting two polio-stricken children holding on to a rail while they exercise their lower limbs. In the early 1950s there were more than 20,000 cases of polio each year. After the polio vaccination was introduced in 1955 that figure dropped to about 3,000 per year by 1960.
