Introduction:
Pressure vest is usually used as a training intervention for the treatment of autistic children by medical experts. This article assessed the effect of pressure vest on attention and involuntary behaviors of children with autism.

Aim:
The aim of this study is to expand the pressure vest therapy as a new non-invasive method to treat the autism spectrum disorder.

Material and methods:
Pressure vest have cells dilated to apply pressure to the body and an air compressor manually adjustable for proper functioning. It is needed to apply pressure in a different way to enter some dynamic pressure that has a characteristic rhythmic massage. In this study, we used an alternative treatment plan for five children with autism within seven days of seven weeks. At first, the vest was worn to the baby and then a series of tasks and common games were performed. The Micro had three different programs to control valves of pressure vest.

Results and discussion:
Children in most cases did the exercises and assignments with interest and had more patience. Assessing four main parameters including the focus, anger, learning and speaking in children indicates that at the end of the seven-weak course, the behavior of children has improved in the form of a reduction in the anger level and the improvement of speaking, learning and focus. The device had an acceptable performance in the prevention of sudden behaviors. The major advantage of these vests were increasing focus and concentration, enhancing comprehension and learning and reducing hyperactivity.

Conclusions:
Further work with a larger database of subjects and different psychological evaluation methods is required to confirm our findings. The Micro three different programs to control valves of pressure vest had no significant effects.
