PHYSIOTALK with Caitlin - Helping Flexible Kids Stay Strong: Understanding Hypermobility in Children
Have you ever noticed a child who can easily do the splits, bend their fingers backwards, or sit in unusual positions without discomfort? While many people describe these children as simply being ādouble-jointedā or naturally flexible, this increased flexibility can sometimes be a sign of hypermobility.
Hypermobility refers to joints moving beyond the typical range expected for a childās age. In children, some flexibility is completely normal because their bodies are still developing, however for some kids, excessive joint movement can place extra strain on muscles, ligaments and growing joints. While some children with hypermobility experience no problems at all, others may struggle with pain, fatigue, poor coordination, frequent sprains, clumsiness, or difficulty keeping up with physical activities.
Parents are often the first to notice the signs. Children with hypermobility may complain of āgrowing painsā more often than expected, tire quickly during sport, avoid playground activities, sit in slouched or unusual positions, or seem more injury-prone than their peers. Some children may even begin withdrawing from hobbies or sports they once enjoyed because movement becomes uncomfortable or exhausting.
Unfortunately, when hypermobility is not recognised or managed well, the impacts can extend beyond childhood. Ongoing joint stress and repeated injuries may contribute to persistent pain, reduced confidence in movement and lower participation in physical activity over time. This is particularly important because regular movement and exercise play a crucial role in childrenās physical health, mental wellbeing, social development and long-term health outcomes.
This is where physiotherapy can play an important role. A physiotherapy assessment helps identify how hypermobility may be affecting a childās strength, balance, coordination, endurance and movement patterns. Importantly, physiotherapy is not about telling children to stop being active. Instead, the goal is to help children move well, build strength and develop confidence so they can continue participating in the activities they enjoy.
Physiotherapy management may include strengthening programs to better support the joints, balance and coordination activities, strategies to improve posture and movement control, education around pacing and fatigue, and guidance on safe participation in sport and recreation. Small changes in how children move, recover and train can often make a significant difference to pain levels, injury risk and confidence.
If your child frequently complains of pain, tires easily, avoids physical activity or seems unusually flexible, we strongly encourage seeking a physiotherapy assessment early. Every child and family is different, which is why management should be tailored to suit the childās specific needs, goals and lifestyle. With the right guidance and support, children with hypermobility can build strength, confidence and resilience, allowing them to continue participating in the activities they love.
