Motor Impairment

A condition that affects a person's ability to control physical movements, including fine motor skills (precise movements of hands and fingers) and gross motor skills (larger movements involving arms, legs, and trunk). Motor impairments can result from conditions such as stroke, cerebral palsy, multiple sclerosis, Parkinson's disease, arthritis, or injury. In digital accessibility, motor impairments affect keyboard use, mouse control, touchscreen interaction, and gesture input. Accessible design accommodates motor impairments through keyboard alternatives, larger click targets, adjustable timing, voice control, and switch access compatibility.
