Synchronous treatment Viofor rings can be used simultaneously with another flat applicator – a mat or pad – during treatment. Topical treatments with the ring applicator can be combined with systemic treatments with mat applicators. By using two applicators synchronously during treatment, the magnetic field becomes more homogeneous and the treatment surface area is larger, thus increasing the effectiveness of the therapy. Connecting the ring to another applicator is done via the Viofor adapter (Ref. 1073).
