Scientists have found that the appearance of a child’s backside may reveal a hidden sign of autism or attention-deficit hyperactivity disorder (ADHD).
Multiple studies over the last decade have examined a peculiar change in the posture of children under ten years old, which makes their backside look bigger or more prominent, like a ‘duck butt,’ even though it’s not actually larger.
According to observations of kids with autism spectrum disorder (ASD), these children often exhibited a more forward-tilted pelvis while walking, about five degrees more on average, compared to children without the condition.
Autism is a condition that affects social skills, communication, and behavior, often leading to repetitive actions or sensitivities to sound, light, or smell.
The condition can also lead to behaviors such as toe-walking or spending long periods sitting in repetitive positions, which tighten the hip flexor muscles and contribute to this pelvic tilt.
All of this makes it harder to maintain a balanced posture, causing children with autism to compensate awkwardly in how they stand and walk.
