The Technology Related Assistance to Individuals with Disabilities Act of 1988 described an assistive technology device as "any item, piece of equipment, or product system, whether acquired commercially off the shelf, modified, or customized, that is used to increase, maintain, or improve functional capabilities of individuals with disabilities."
Assistive technologies can be "high tech" and "low tech:" from canes and lever doorknobs to voice recognition software and augmentative communication devices (speech generating devices).
People who have lower limb differences may need assistance with mobility. Some mobility aids include:
Mobility varies with each person. Some people with a lower limb difference may be able to walk with the assistance of crutches or a prosthetic, while some may use a wheelchair.
There are many types of prosthetic limbs. They vary based on what limb the prosthetic is for, what the person using it's needs are, and what kind of limb difference they have. Some prosthetics are built for specific physical activities, such as running, walking, biking, grasping, or hooking. Some are powered by the bodies movement and some may have an extra power source. Some prosthetics may be purely cosmetic. Some common types of prosthetic include:
Leg prostheses are categorized as transtibial or transfemoral.
Arm prostheses are categorized as transradial or transhumeral.
