Rehabilitation engineering

Rehabilitation engineering is the systematic application of engineering sciences to design, develop, adapt, test, evaluate, apply, and distribute technological solutions to problems confronted by individuals with disabilities. These individuals may have experienced a spinal cord injury, brain trauma, or any other debilitating injury or disease (such as multiple sclerosis, Parkinson's, West Nile, ALS, etc.).
