Rayonex Biomedical conducted a significant clinical prospective, double-blind, randomised and placebo-controlled study on pain reduction in patients with cervical spine syndrome, proving the efficacy and safety of Bioresonance according to Paul Schmidt in the treatment of chronic pain. The Rayoscan is a fully automatic energetic test based on ECG analysis, evaluating 22 physiologies in a check-up test and determining those physiological areas that are particularly in need of treatment. Following the selection of the physiological areas, an automatic cause-oriented detailed test is carried out to find the pathological burden. A Progress Control shows the course of the therapy, e.g. on a weekly or monthly basis.
