Motor
Mobility impairment is a broad category of physical disabilities that include upper limb and manual dexterity disabilities, loss of fine-motor control, and disabling conditions such as cerebral palsy and carpal tunnel syndrome. The disabilities may be temporary or permanent; they may range in severity from mild loss of fine-motor control to quadriplegia; they may be the consequence of aging, accident, heredity, disease. Users may have limited arm or hand movement, use just one hand, have a tremor, have difficulty with fine movements, or be unable to hold a mouse.
