Yes. My eg/pg ds6 was born with severe sensory integration and had asynchronous development partly from the giftedness, but also partly from being born with torticollis (neck) and low muscle tone due to uterine constraints. He spent over 4+ yrs in a sensory processing ot gym.
My son had ot for 5+ years, essentially since 2 months old. I had many ots say that he was bright, though not eg/pg. They definitely had to adapt exercises for him - very early on. Otherwise they would lose his attention. He went from severe sensory avoidance to sensory seeking before coming back to the middle ground. He had severe sensory intensity - with vestibular, auditory, visual, tactile, oral, proprioceptive - the works (years of pt/ot/speech/feeding/vision therapies and other interventions, including neck surgery).
I firmly believe that the torticollis, sensory integration, low muscle tone, visual processing deficits (sensory again!) were interrelated and actually enhanced any predisposed genetic intelligence with my son. I don't know how many other torticollis kids develop so unusual like my son because there's so much misinformation on torticollis as it is and I don't think there are any long-term studies on them.
I've spent a much longer time dealing with sensory and my son's special needs than I have been dealing with the eg/pg stuff that it can feel strange at times.
