Unique, non-invasive and non-traumatic therapy method with strong pain-reducing potential.



DEEP OSCILLATION® is an internationally patented, proven technology based on the effects of creating an electrostatic field in the tissue of the patient. Easy application is from therapist to client via hygienic, vinyl gloved hands; utilizing all normal massage movements or via circular movements over the tissue with a handheld applicator. The handheld applicator also enables self-treatment.

The special structure of DEEP OSCILLATION® allows the creation of biologically effective oscillations in the treated tissue using electrostatic attraction and friction. In contrast to other therapies, these pleasant oscillations have a gentle and deep-acting effect on all tissue components to an 8 cm depth (through skin, connective tissue, subcutaneous fat, muscles, blood and lymph vessels.

Because of the non-invasive, non-traumatic, gentle nature of this therapy, very early possibilities of application are possible following injury and from Day One post operatively. Chronic conditions can also be worked upon with effective results.

The following physiological effects of DEEP OSCILLATION® are clinically proven: 

  • Highly effective in reducing pain
  • Anti-inflammatory
  • Effective in reabsorbing oedema (swelling)
  • Encouraging wounds to heal
  • Fibrosis Reduction
  • Improving trophicity
  • Rubor reduction (haematoma/bruising)
  • Detoxification
  • Improving quality of tissue
