Hypotonia

A condition characterized by decreased muscle tone, resulting in reduced resistance to passive movement and often affecting posture and motor control. Hypotonia is common in many developmental disabilities including Down syndrome, cerebral palsy, and various genetic conditions. In the context of computer accessibility, low muscle tone affects the ability to maintain posture while using devices, sustain repetitive motions like typing, grip input devices firmly, and apply consistent pressure for clicking or key presses. Children with hypotonia may fatigue quickly when using standard keyboards and mice, making alternative input devices, ergonomic supports, or frequent rest breaks important accommodations.
