Physical disabilities arise as a result of congenital defects, accidents or a progressive neuromuscular disease like Lou Gehrig's Disease, stroke, Parkinson's Disease, multiple sclerosis or muscular dystrophy. These workers often require the use of a wheelchair, adaptive seating or other reasonable accommodations. Assuming the worker otherwise qualifies for the position in terms of education, certification and experience, the employer must make reasonable accommodations for the disabled person. People with physical disabilities can secure employment in information technology, engineering, accounting and finance, and other professional fields.
