I was a teacher that worked with children with disabilities and can assure you that putting them in a "rubber room" will do more harm than good. These children need "special" attention and understanding and most of all"compassion". NO child should ever under any circumstance be put in a "rubber room".
These tactics were used "back in the day" in insane asylums. It was and is "barbaric" and violates the dignity of a child.
I hope the parents fight this tooth and nail and eliminates this inhumane practice.
