Disability is not always restricted to the senses. Limbs that do not work or have been lost often cause a person to change their life. A walk in the park is a pleasant way to spend a sunny day unless walking cannot be done because of a lost leg. For these people, it is a struggle to be able to move around. They are disabled in a profound way. Fortunately, modern technology offers assistance to those with missing legs.
Prosthetics have long been available, and they are used in place of missing legs. In previous centuries, these items were made of wood. They were often very heavy and painful to use. Modern technology has combined plastics and lightweight metal to create limbs that are approximately the same weight as a normal leg. These artificial limbs are now made in various configurations for the many activities enjoyed by the user.
