yes we did it and some thought it helped for a short time after (lots of things did that) but didn't make long term results, but who knows, you can't unring a bell so it didn't hurt him...
I just had a new evaluation done while he was in pt. and they are recommending many things again, especially because he has so many sensory issues. He is really disregulated and the Occupational Therapist (OT) and doctor both felt like this was a huge reason he is so aggressive, he just can't control the level of touching and frequency. He also (once again) scored high for auditory processing problems etc. So, if they recommend it again when we go to private Occupational Therapist (OT) again, I am willing to try again.
I have worked with kids who have used it and actually were able to be toilet trained easier. Others we didn't see much of a change but they loved it anyway. We incorporated it right into our ecse preschool classroom for those who needed it and just tag teamed them, then some spinning, and pecs work while they were positioned on balls etc.... It is all good. If you decide you are interesed, have an Occupational Therapist (OT) evaluation, then follow their directions exactly.
Let us know how it turns out for you....
