perplexed I think that hypermobility is not necessarily a symptom OR a cause of SPD, maybe it is for some children, and maybe it's often co-morbid. But certainly for our family the hypermobility is genetic, and tied to ehlers danlos disease. My DD has just been re-assessed by our OT as essentially having all her SPD issues "resolved" or at least well adapted to - but the hypermobility is, in the OTs opinion, there for life (but not presently causing any particular issues, her core and limbs are "surprisingly strong for how hypermobile she is" & her pencil grip is ok, with her writing speed on the 63rd percentile for age).
