Autism and Ehlers-Danlos Syndrome

The Link Between Autism and Ehlers-Danlos Syndrome

Autism and hypermobility may seem unrelated at first, but many families are discovering meaningful overlap between the two. For some autistic children, physical discomfort plays a much bigger role than expected.

Years ago, I supported a child who avoided sitting tasks and movement-based play. At first, it looked behavioral. Later, we learned joint instability was causing real pain. Once physical needs were addressed, the child’s engagement in our home-based ABA therapy sessions changed dramatically.

Understanding the Link Between Autism and Hypermobility

Research and clinical experience are showing a growing overlap between autism and connective tissue conditions, including Ehlers-Danlos Syndrome (EDS) and generalized joint hypermobility.

While autism is a neurodevelopmental condition and EDS affects connective tissue, many children experience traits of both. This connection is still being studied, but awareness is growing among medical and therapy professionals.

Parents often notice:

Extremely flexible joints
Frequent joint pain or injuries
Poor coordination or balance
Fatigue or low muscle tone
Sensory sensitivities related to pain or body awareness

So why does this connection matter for autistic children?

Hypermobility can affect much more than joints. For autistic children, it may also impact behavior, learning, and emotional regulation.

When a child’s body feels unstable or painful, it can show up as:

Difficulty sitting still
Avoidance of physical activities
Increased meltdowns or shutdowns
Trouble with handwriting or fine motor tasks

Understanding the physical side of what your child is experiencing can bring clarity—and often relief—to parents who have been searching for answers.

Signs Parents May Want to Look For

Not every autistic child with flexibility has EDS, but some signs may be worth discussing with a healthcare provider.

Physical signs

Joints that bend beyond typical ranges
Frequent sprains or “growing pains”
Flat feet or poor posture

Functional signs

Tires easily during play or school
Difficulty with coordination
Pain after physical activity

Early awareness can help families seek the right evaluations and supports.

Supporting a Child With Autism and Hypermobility

Support often works best when it’s collaborative. Occupational therapy, physical therapy, and behavioral support can work together to help children build strength, stability, and confidence.

Simple supports may include:

Strength-building activities
Movement breaks that protect joints
Adjusted expectations for physical tasks
Clear communication around pain and fatigue

Most importantly, children benefit when their physical needs are understood—not dismissed.

At Connect N Care ABA, we believe behavior never exists in isolation. Physical comfort, sensory needs, and emotional regulation all matter—especially for autistic children with complex needs like hypermobility or EDS traits.

We proudly support families across North Carolina and Virginia with compassionate, individualized care.

Our services include:

ABA therapy at home to support daily routines while respecting physical needs
School-based ABA therapy to help children succeed in academic settings with appropriate accommodations
Center-based ABA therapy for structured support that considers the whole child

FAQs

Is Ehlers-Danlos Syndrome common in autistic children?
Not all autistic children have EDS, but joint hypermobility appears more frequently in autistic individuals than in the general population.
Can hypermobility affect behavior?
Yes. Pain, fatigue, and instability can contribute to emotional dysregulation, avoidance, or increased sensory sensitivities.
Can ABA therapy help if my child has physical challenges too?
Yes. ABA therapy can be adapted to respect physical needs while supporting communication, daily skills, and emotional regulation.
