Upper Limb Motor Impairment

A condition affecting movement, strength, coordination, or fine motor control in the hands, wrists, arms, or shoulders that impacts a person's ability to use standard computer input devices. Causes include cerebral palsy, spinal cord injury, stroke, multiple sclerosis, Ehlers-Danlos syndrome, arthrogryposis, chronic pain conditions, and repetitive strain injuries. People with upper limb motor impairments may experience limited range of motion, reduced grip strength, imprecise fine motor skills, tremors, pain during use, or inability to perform multi-key combinations. These impairments require adaptations ranging from software accessibility settings to alternative input devices and customized workarounds.
