What is hypermobility?
Hypermobility is when various joint moves beyond normal limits. Its what many people used to call double jointed. And for most people, it’s a variant of normal and doesn’t cause any problems. It even means they might excel at sports that require flexibility like dance or gymnastics.
Types of hypermobility:
• Hypermobility can be associated with medical condition like Ehlers-Danlos Syndrome and Marfan Syndrome. If your child has other symptoms besides excess joint range you should talk to your doctor.
• Up to 35% of children have a condition called benign joint hypermobility syndrome. This means that some of their joints move beyond normal but this isn’t associated with another medical condition.
• Swelling and joint asymmetry is not part of the normal presentation of benign joint hypermobility syndrome. If your child has these symptoms you should see a doctor.
Hypermobility throughout childhood:
Hypermobility in infants can make it harder for them to control their joints to learn to crawl and walk. The good news is, if your child is bendy but is meeting all their milestones (like crawling and walking), they will likely continue to do so and be able to fully participate in activities with other children. If your child is not meeting their gross motor milestones (or if you are not sure that they are) it is important that you have them checked by a doctor or a physiotherapist.
In preschool aged children, you may notice that your child has difficulty gripping and manipulating fine objects. They might have trouble sitting on the floor with their legs crossed or on a chair and instead choose to lie on their tummy, W-sit (with their bottom on the floor and legs tucked behind in a W) or slide forward in the seat.
In school aged children, you may notice difficulties with handwriting, fatigue, complaining of aches and pains or difficulty keeping up with walking and running.
Is my child more likely to get injured?
Most children with hypermobility do not get pain or increased injuries. However, some children do get pain in hypermobile joints, particularly when they have used the joint a lot. They may also be susceptible to sprains and other soft tissue injuries because the ligaments around their joints allow so much movement.
What should I do about it?
It is shown that children with hypermobility who stay active and strong have very few problems with their hypermobility as they grow up. Swimming, riding a bike and participating in school sports are all part of an active and healthy childhood. If your child has trouble participating in these activities you should see a physiotherapist or an occupational therapist to discuss ways to work toward your child being able to safely participate.
