Upper-Limb Impairment

A physical disability affecting the arms, hands, or fingers that limits a person's ability to perform fine motor tasks such as typing, using a mouse, or operating touchscreen devices. Upper-limb impairments can result from conditions including spinal cord injury, stroke, repetitive strain injury, cerebral palsy, amputation, or neuromuscular diseases. In digital accessibility, upper-limb impairments are significant because most computing interfaces rely on keyboard and mouse input. Alternative input methods include speech recognition, eye tracking, head tracking, switch access, and adaptive keyboards or pointing devices.
