Motor Disability

A condition that affects a person's ability to control voluntary muscle movements, impacting mobility, dexterity, coordination, or speech production. Motor disabilities can result from neurological conditions (cerebral palsy, ALS, multiple sclerosis), spinal cord injuries, muscular disorders, or acquired brain injuries. In digital accessibility, motor disabilities may affect keyboard and mouse use, requiring alternative input methods such as switch access, voice recognition, eye tracking, or head pointing. Interface design considerations include adequate target sizes, reduced precision requirements, and accommodation for fatigue and variable motor control.
