Physical disabilities are often misinterpreted for something they are not. More times than not, a physical disability is mistaken for a mental disability. A physical disability is defined as a physical and/or motor impairment. A physical disorder like cerebral palsy is sometimes confused for a mental disorder because of the way it affects the body's muscle movement and mobility skills. Asking why someone with cerebral palsy can talk is like asking, "Why doesn't the arthritis in your wrists affect your speech?" neither is comparable and neither and has nothing to do with the other. In the United States alone, there are about 74.6 million people who have some sort of physical disability. This makes up the largest minority group in the U.S. Of that 74.6 million, 27 million are woman. When people think of physical disabilities, they do not take into consideration that these disabilities do not in fact affect the brain, but only the muscle movement in the body. It is very important to know the difference between physical and mental disabilities and to be aware that other around you may be suffering from either one, or possibly both.
