How it Works

Since Michael Faraday discovered magnetic induction in 1831, we have continued to further our understanding and exploit the benefits of the interdependence of electricity and magnetism. Passing current through a coil of wire generates a magnetic field perpendicular to the current flow in the coil (right hand rule). If the coil is placed near a conducting medium, such as human tissues, and a time varying current is introduced into the coil, current will be induced in the conducting medium as a result of the changing magnetic field produced by the coil. One can think of the magnetic field produced by the coil as a non-invasive conduit between the electric current in the coil and the induced current in the tissues.


ExMI™ offers renewed hope to those patients whose only previous treatment options were surgery, drugs or behavioral therapies.

Over the last 50 years, engineers and scientists have provided many new solutions to medical problems by allowing physicians to non-invasively enter the body. This has been done with a number of forms of energy to help diagnosis disease and trauma (x-ray, CT, MRI, ultrasound, etc.), and in a few cases, actually provide a therapy as with lasers, kidney stone lithotripters and gamma particle devices (Gamma Knife®). Pulsed magnetic neuromodulation provides the first non-invasive and focal technique to excite neurons to positively impact cell function and are neurologic and neuromuscular disorders.

Clinical trials are underway to explore further applications of Extracorporeal Magnetic Innervation (ExMI) technology. Preliminary reports indicate a significant role of ExMI in cardiovascular disease, wound care, peripheral neuropathy (in diabetic and chemotherapy patients), orthopedics, stem cell research, rehabilitation for stroke patients, cancer treatment, and other applications including cosmetics.

The technology that makes this treatment possible is Extracorporeal Magnetic Innervation, or ExMI™ for short. Cleared by the US Food and Drug Administration (FDA) in June of 1998, the technology received TGA approval in Australia in 1999.

Wave Brilliance Australia embraces the ExMI™ Pelvic Floor Therapy System, a non-surgical therapy for the treatment of stress, urge and mixed incontinence, prolapse and pelvic pain in women, incontinence and erectile dysfunction in men. For patients whose incontinence is caused by a weakening of their pelvic floor muscles, ExMI™ can offer unique therapeutic benefits. Unlike other therapy options, ExMI exercises all of the muscles in the pelvic floor to rebuild strength and endurance and restore bladder control. ExMI™ accomplishes this while the patient sits fully clothed in a comfortable chair.

The process is similar to Kegel exercises for the pelvic floor. While conventional Kegel exercises (or "Kegels") enhanced by biofeedback techniques can help to restore continence, women often perform the exercises incorrectly, incompletely, or inconsistently. With ExMI™, the system performs the exercises for the patient in a more complete and effective manner than the patient could do on their own. No active participation by the patient is required.
