Rollers are applicators for dynamic use. All parts of the body can be effected by them: back, chest, abdomen, extremities, zone of backsides. It is recommended for application by the adults and children. Using the roller it is possible to render calming (sedative) or activate (toning) action. For achieving calming effect (for example, at pains in sacrolumbar areas or in lower extremities) a treatment session should last 10-15 minutes. Needles of the roller are in contact with skin but they do not damage it. The method is effective and non-ivasive, so it completely excludes an infection carry (virus hepatitis, AIDS). The diagnostic method is based on the fact that there are certain projection zones of visceral organs on person's body.
