The document discusses locomotor disabilities, which refer to restrictions in limb movement that cause problems moving from place to place. Locomotor disabilities can be caused by conditions like cerebral palsy, polio, amputation, spinal or head injuries, strokes, and other illnesses. They are characterized by poor motor control, coordination issues, awkward or limping gaits, pain with exercise, and frequent falling. Teachers should provide accommodations like accessible classrooms and notes, seating, scribes, and extra time on exams to support students with locomotor disabilities.
