A variety of physical disabilities result from congenital conditions, accidents, or progressive neuromuscular diseases and may limit mobility and/or energy. These disabilities may include such musculoskeletal disabilities such as partial or total paralysis, amputation or severe injury, arthritis, spinal cord injury (paraplegia or quadriplegia), spina bifida, cerebral palsy, active sickle cell disease, muscular dystrophy, multiple sclerosis, polio/post polio, and stroke. Additionally, respiratory and cardiac diseases which are debilitating, may affect mobility. Any of these disabilities may also impair the strength, speed, endurance, coordination, or dexterity necessary for college life. While the degree of disabilities varies, it is important to recognize that for many reasons, some students may have difficulty getting to and from class, performing in class, taking notes, and managing out-of-class assignments and tests.
