If one looks at the history of treatment of young children with autism, one finds a long list of treatments that have been espoused to be the next cure for autism. Many of these treatments have been embraced with no scientific evidence to back them up. Data from carefully controlled studies demonstrating the efficacy of these interventions is often lacking-- in lieu of data, testimonials and anecdotal reports are instead used as proof that the intervention will improve functioning of the child. My personal opinion is that you should be especially careful when evaluating how much scientific evidence there is to support any treatment for autism.
I think that additional research is needed on this treatment because, in my opinion, there is currently no adequate scientific evidence (based on controlled studies using generally accepted scientific methodology) that demonstrates this effectiveness of this treatment for children with autism.
Best of luck!
