Protac has developed a range of products containing balls which, thanks to the deep touch-pressure and constant contact to the body’s surface, activate the sense of touch and the sense of body position and movement. Different products contain different weighted balls that stimulate children’s sensory system having a calming effect. If you are feeling impatient, you may fidget on the chair or tap one of your feet – both everyday examples where we use our sense of movement to calm ourselves down. When the weight of the balls in Protac products offers resistance to the body’s joints and muscles, a message is sent to the nervous system, which the brain registers as movement. This is why the Protac balls have a calming effect.
