People who have physical disabilities may require wheelchairs, crutches, braces or walkers. Some people may make involuntary movements or experience sensory losses. Never assume that people with physical disabilities, including speech and language disorders, are cognitively disabled. A communication disorder is not an indication of intelligence. The limited vision of a person who is blind or visually impaired may interfere with activities, but with understanding, adaptations and accommodations, the individual is capable of performing most expected activities.
Mobility is probably the biggest concern for individuals who are blind or visually impaired.
Hard of hearing individuals often utilize their remaining hearing with the help of amplification. Their ability to understand spoken communication varies. Remember, if someone has difficulty verbalizing, it is not indicative of low intelligence. These terms are no longer considered appropriate in most settings. A person with a cognitive disability is characterized by a below average I.Q. and by problems in adaptive behavior.
