Extracorporeal Magnetotransduction Therapy (EMTT) from Storz Medical

Extracorporeal Magnetotransduction Therapy (EMTT) provides a new, non-invasive procedure for treating chronic musculoskeletal diseases. The Magnetolith® is impressive with its wide range of applications, patient comfort and ease of use.

EMTT relies on a different operating mechanism to ESWT. Whereas Shockwave acts using high-energy acoustic/physical signals in a local treatment area, EMTT acts using high-energy electromagnetic radiation in a regional treatment area.


Advantages of EMTT

  • Non-invasive, outpatient therapy – with almost no side effects
  • Used for musculoskeletal diseases
  • Wide range of therapies
  • High level of patient comfort and easy to use
  • EMTT is a useful addition to ESWT



EMTT – New Possibilities in Therapy and Rehabilitation

Application areas of Extracorporeal Magnetotransduction Therapy (EMTT) include diseases of the musculoskeletal system such as pain in the lower back, arthrosis as well as inflammation in tendons and joints. EMTT differs from other general forms of magnetic field therapy or PEMF in its higher oscillation frequency and magnetic field strength, resulting in a strong, effective transduction power. It can be assumed that the faster the magnetic field pulses or the higher the effective transduction power, the more pronounced the bioelectrical activity in the organism will be. These properties also allow the EMTT to reach a large penetration depth (18 cm) and to cover a wide range of applications.

Typical EMTT Application Areas

Degenerative joint diseases
Wear and tear conditions such as osteoarthritis (knees, hips, hands, shoulders, elbows), herniated discs, spondylarthrosis

Pain treatment
(Chronic) pain, for example, back pain, lumbago, tension, radiculopathy

Sports injuries
Chronic inflammation of tendons and joints, tendon overuse syndromes, inflammation of the pubic bone

EMTT Operating Principle

EMTT treatment can cause positive biological effects. Every cell undergoes chemical reactions that drive metabolism. The prerequisite for this is membrane permeability. A stable cell membrane ensures permeability for vital substances. A pathological change leads to dysfunction – a metabolic disorder that can ultimately lead to disease. The chemical reactions of the cell potential can be positively influenced by EMTT. The sodium-potassium pump can be reactivated and physiological cell processes can be normalised.
