I was wondering if lack of hemispheric dominance is another cause for hypotonia, SPD, dysgraphia.
DS8 is ambidextrous in that he uses either of his hands to eat and write. While working with a kinesiologist, she mentioned that he has mixed dominance - his left leg is dominant, as is his left eye. He recently went for bone conduction therapy for his APD. It did improve his dichotic hearing, but response time from his ears did not improve (worsened actually). What was surprising was that regardless of which side sound input came through the earphones, he'd think it came from the left. ie, if it came from the right side of the earphones, he'd still think he heard on the left ear. His right ear processing speed is really slow, way slower than his left.
I'm wondering if his issues (sensory processing, visual processing, poor sports coordination, auditory processing, poor handwriting although this has improved significantly) are partly a result of mixed laterality? It does seem like there is some connection.
