we didnt use brushes. my daughter didnt like it.
We made a jump and crash pad. It was a mattress in the floor...she was almost three when we started, so a trampoline might work better for someone older, which we eventually got.
I would get my kids on the mattress and teach them to jump, fall, roll....pillows were used to create the same feeling temple grandin experienced in her squeeze machine.
If the theory is that the body's neurons are not messaging where the body is in space, which is something literature describes in autism, then all this movement of the body that can be hyper and crushing without getting hurt could help pathways reroute, to allow a better sense of one's body movements.
Swings are great! They create an imbalance in the brain that the brain automatically needs to try and correct. Pathways may be formed or rerouted when the brain is challenged.
Deep pressure massage.....especially for the larger muscles in my child....hips, thighs, buttocks, and upper arm. She still seeks this. Me too!
I think pools should always be included, but a tub will always do. It changes the way the body feels, again challenging the brain to work in ways it should.
Manipulatives for the hands, should be part of the program for those whose hand strength is lowered.
Touch, taste, smell, sight, and even hearing should be addressed in a complete program, by offering the body and mind different sensations. Challenging the brain to make sense of all the incoming data through the senses.
hope this helps.
