Today I had a really fascinating case. The school staff were convinced this little boy was simply “clumsy” maybe because of his hypermobility. But there was a big sensory-processing piece hiding underneath all of that!
When people hear “sensory processing,” they usually think of kids who dislike loud noises, hate certain clothing textures, or gag on lumpy food. But there’s another side to sensory processing that’s often forgotten: proprioception and kinesthesiathe “secret senses” that tell us where our body is and how it’s moving without needing to look.
Children with hypermobility often have less joint stability, which means less information coming from the joints. Imagine trying to navigate with a blurry map that’s what the brain is working with. So while the school was told to “just build up those weak muscles,” the real story was much more complex.
Most of the research on proprioception and hypermobility has been done by PTs and focuses on the legs walking, running, mobility. But almost no research has looked at hand skills or everyday living tasks. That’s where we, as OTs, come in. We get to teach parents, teachers, and caregivers how sensory processing and motor performance are deeply intertwined and how to support kids using this knowledge.
Here’s a simple way to understand proprioception and kinesthesia: Think about touch-typing Your ability to place your fingers correctly on the home row without looking? That’s proprioception.nYour ability to feel that you accidentally hit “w” instead of “e”? That’s kinesthesia. People often call it “muscle memory,” but that’s not really true muscles don’t remember anything. Brains do. And if the brain isn’t getting the right information, it can’t send out the right instructions.
So why do kids with hypermobility struggle with these senses?
Because the receptors that send position and movement information to the brain sit in the joints and surrounding tissues. When the joints are loose, those receptors don’t get enough stimulation—kind of like tapping a carnival strength game but not hitting it hard enough to ring the bell. The brain gets weak, slow, or incomplete signals, so its responses aren’t as accurate.
This can show up as:
1. slouched posture
2. difficulty catching a ball
3. slow reactions
4. heavy-footed walking
5. awkward or unusual sitting positions that look painful—but somehow aren’t
(There’s a whole article’s worth to say about why kids with hypermobility love extreme positions others would avoid!)
Parents often wonder, “How do I know if proprioception is affecting my child’s function?” A big red flag is safety. Kids who can’t accurately sense changes in balance or body position can become unsafe very quickly. And safety isn’t a small issue it's the foundation for confident exploration and development.
