dear Mercedese,
It is possible that you have been using the vibrogym for too long a period of time.(meaning more than 20 min)
Please check this article....
http://onlinelibrary.wiley.com/doi/1...09.03418.x/pdf
this second article is about the effects of vibration on children with cerebral palsy.
http://www.ismni.org/jmni/pdf/39/10RAUCH.pdf
Both make a good read and should help you (and your therapist) decide how to go on from this point.
This last one compares various treatment options to vibration therapy in adult cerebral palsy patients.
