Too Flexible? Understanding Hypermobility in Your Child

We often hear parents say their child is “double-jointed” because they can bend their elbows or knees in ways that look amazing. Extreme flexibility, known as hypermobility, can seem like a superpower, but for some kids, it means their joints are unstable, leading to fatigue, pain, or difficulty with certain movements. At Breathe. Physical Therapy & Wellness, we help children with hypermobility learn how to use their “extra stretchy” joints safely and confidently, turning a challenge into a strength.

What Is Pediatric Hypermobility?

Hypermobility means the ligaments—the strong bands that hold joints together—are naturally looser or more elastic than usual. This allows the joints to move beyond their typical range. While some children thrive with this extra range, others may struggle with the lack of natural “stop” in the joint. This makes their muscles work overtime to provide stability, often leading to tiredness or minor injuries.

Why Some Hypermobile Children Need Extra Support

Signs Your Child Might Need Support

If your child is hypermobile, you might notice signs that indicate their body is working too hard to stay stable:

Quick Fatigue During Play

They get tired easily during physical activity, like needing frequent breaks during play or sports.

“W” Sitting

They sit with their knees bent and feet outside their hips in a “W” shape, as this posture requires less core and muscle effort to stay upright.

Frequent Sprains or Growing Pains

Because joints move too far, they are more prone to minor sprains or general “growing pains,” especially in the shins, knees, or ankles.

Clumsiness or Poor Coordination

They might frequently trip, drop things, or seem clumsy because their brain has trouble knowing where their flexible joints are positioned in space.

How Pediatric Physical Therapy Helps Hypermobile Children

For a child with hypermobility, the goal isn’t more stretching; it’s the opposite: stability and strength. Our play-based therapy focuses on teaching the muscles around the joints to be the primary support system.

Building Core and Hip Strength

We use fun, challenging games to strengthen the core, hips, and shoulders.  When the core is strong, the flexible joints have an easier job.

Improving Body Awareness and Balance

We use activities that challenge their sense of balance and position (proprioception), helping their brain know exactly how far they can safely bend or extend their joints. This helps reduce accidental sprains and improves coordination.

Teaching Safe Movement Habits

We coach children and parents on how to move in ways that protect the joints, such as avoiding locking their knees or elbows during standing or weight-bearing activities.

Helping Your Child Build Strength and Confidence

Hypermobility is a trait, not a diagnosis that limits play!

When Should You Consider Pediatric Physical Therapy?

With the right guidance, we can help your child build a strong, stable foundation so they can run, jump, and play without pain or quick fatigue. Let us help them find their inner strength and confidence.
