Because FD Roosevelt was stricken with polio at a young age, he could not walk. He had to have braces strapped to his legs to support when he stood. This meant the arduous task of putting on the braces, followed by the shoes, then finally his pants over the braces and shoes. The procedure took about an hour. The next step was to make it look he could walk. He held onto his son with one hand and had a cane in the other. He could not move his legs and therefore threw his shoulders forward one at a time in alternate movements. This made his body move forward, giving the illusion he was walking.
