I recently discovered a book recommended by a friend called Disconnected Kids: The Groundbreaking Brain Balance Program for Children with Autism, ADHD, Dyslexia, and Other Neurological Disorders. I find the recommendations promising and they make me feel hopeful again. Another thing I've been reading up on is Primitive Reflexes. If you Google it, you can find a lot of info, and the theory is compelling. Bear in mind these treatments aren't proven, but I've tried most of the proven treatments with very little change in the SPD symptoms. Occupational therapy has helped a little--mostly with coordination and gross motor skills, Therapeutic Listening has helped a little--with calming and less frustration, and the Feingold Diet dramatically changed my daughter's behavior--went from many meltdowns a day and being belligerent most of the time to very cheerful and very rare meltdowns. Her basic SPD symptoms haven't improved a lot--still puts inedible objects in her mouth, can't resist touching everything, very impulsive, easily distracted, requires constant supervision, trouble following directions, doesn't notice smells, doesn't notice if her face is dirty or clothes are disheveled, can't identify items by touch, not 100% potty trained (will be 6 in a month) and other internal regulation issues, very loud talker, difficulty writing/drawing, other kids are turned off by her lack of social appropriateness. Consequently, I'm willing to try some alternative therapies at this point. We're meeting tomorrow night with the Brain Balance Centers doctor to determine if we want to sign up for the program promoted in the Disconnected Kid book. Based on your description of your son, if it were me, I'd concentrate on doing exercises to get rid of the primitive reflexes.

I hope this helps. We're all in this together, so keep sharing your ideas and asking questions.
