Definition
Hypotonia means low muscle tone, where muscles feel softer or looser and take more effort to hold steady. It is common among autistic children and can affect posture, sitting upright, grip, and stamina. A child with hypotonia may tire quickly, slump, or seek support to stay stable. It reflects how the muscles rest, not their strength or determination.
Why It Matters
Knowing about hypotonia helps you understand why sitting still, handwriting, or long activities can be exhausting for your child. Supportive seating, movement breaks, and patience with fatigue honor their body instead of reading tiredness as laziness or a lack of trying.
Common Misconception
Low tone is often mistaken for weakness, clumsiness, or being unmotivated. Tone and strength are not the same thing. A child can work very hard and still slump, and pushing them to just sit up straight ignores the real physical effort involved.
