LinCO,
Thanks for bringing these therapies up.
One of my son's OTs was very well-versed in Masgutova method, and we certainly saw gains and improvements with this, although we didn't get full reintegration of his numerous retained reflexes. I'd absolutely recommend it for children who have retained infantile reflexes.
Essential fatty acids are rarely a bad idea, but we didn't see any dramatic improvement in hypotonia from using the supplements (although there were other things that did improve.)
I'm pretty sure gymnastics or wrestling would have been 1) incredibly dangerous and 2) impossible for my son, whose disabilities also seriously impair his depth perception and his proprioception, so I am grateful that we had the excellent private OTs and PTs who managed to help us get him to where he is today. He wasn't in school once he was diagnosed, so we never dealt with school OT and PT, which I understand can be very different from what you find in private practice.
