Hi
can anybody tell me what is the difference with Hypermobility and Hyptonia.
And do they always go together?

my dd3 has both, but I don't think they always go together. Hypotonia is low muscle tone, for dd3 this means she is not as strong/has as much stamina as her peers. For her, the hypermobility means that her joints bend further than they should, so she can easily bend her thumb back to touch her wrist etc.

They don't always go together. Hypermobility causes more problems early on if there is low muscle tone, which is why they tend to be diagnosed together. It's estimated that about 1 in 8 people have hypermobility in some joints but nowhere near that many have problems with it until they are older - and for some (gymnasts, dancers etc) it can be a huge advantage, so long as they have good muscle tone.

And it can go the other way - people with hypermobile joints can end up with very tense muscles as they compensate for wobbly, unstable joints. That's a problem for me. I do have generally low muscle tone in a relaxed state, but my thighs are the sort you could crack walnuts with. Used ot be great, but now it just hurts.

As Ninja and ouryve say they are different in that hypotonia means low muscle tone, whereas hypermobility means over flexibility of the joints. Ds has gross hypotonia (general low tone in all his muscles), but no hypermobility.

Ok so dd had an occupational therapy assessment and un the report it said that she has a known diagnosis. Of GDD and hypotonia. (first I'd been told of hypotonia)
But when she was about 2 the Physio said briefly in conversation that she has "loose hips"
But loose hips dosent mean hypotonia does it?
Would loose hips mean hyper mobility then?
