My knowledge of the benefits of this therapy are sketchy at best, but the use of Cranio-Sacral or Sacro-Occipital Therapy in the USA, may be of benefit in helping your son. For more information go to the webpage Upledger.com for the Cranio-Sacral Therapy and they wil have means of communicating with practitioners who can help you. The SOT may be found through the chiropractiv associations web page. Good luck
