Ivivi Technologies, Inc.�s (AMEX: II) non-invasive, pulsed
electromagnetic field (PEMF) technology increased tensile strength
in a standard wound model in rats by 59% after 21 days, researchers
reported in the August 2007 journal of Plastic and Reconstructive
Surgery. The study was conducted at the Montefiore Medical Center,
in The Teaching Hospital of the Albert Einstein College of Medicine
in New York. PEMF signals have accelerated the physiological
processes involved in healing in multiple clinical studies. �PEMF
signals accelerate biomechanical wound healing. These wounds healed
faster and were stronger, earlier, than those that weren�t
treated,� said Dr. Berish Strauch, of the Department of Plastic and
Reconstructive Surgery at Albert Einstein, in whose lab the study
was done. �This study represents the first objective data on the
effect of PEMF on healing rates of cutaneous wounds at the cellular
level. Although the mechanisms of action are not fully known,
previous studies have shown that PEMF enhances the production of
wound healing factors that reduce the time of the inflammatory
phase as well as accelerates the production of the animal�s own
growth factors including Vascular Endothelial Growth Factor (VEGF),
which modulates new blood vessel growth. This study shows that a
specifically configured PEMF signal yields the best result.� �As we
get a clearer picture of the transduction properties of the
physiological pathways involved in tissue repair, we can configure
new PEMF signals,� said Dr. Arthur Pilla, Professor of Biomedical
Engineering at Columbia University, Ivivi Science Director, and a
co-author of the study. �We are increasingly able to fine-tune the
configuration of PEMF signals to achieve a more optimal �dose� for
different indications, as evidenced in this study.� Dr. Pilla
invented the bone-growth stimulator, an early medical application
of PEMF technology. �If a patient can be discharged earlier after
surgery, not only can that patient return to an active lifestyle
more rapidly, but healthcare costs can be reduced,� commented
Andre� DiMino, Vice Chairman and Co-CEO of Ivivi Technologies, Inc.
�Thus, if we can increase the strength of a wound at an earlier
stage in the postoperative period, we can offer an absolute
improvement on patient outcomes with a simple non-invasive
technology with no known side effects.� About The Study The study
involved 100 rats, each with a linear skin incision on their dorsum
that was subsequently sutured and treated with non-invasive PEMF
signals. The study was prospective, placebo-controlled and double
blinded and designed to test different PEMF signal configurations
for 21 days. Four different signals were used targeting the
calcium/calmodulin pathway which is at the start of the
anti-inflammatory and growth factor stages of tissue repair. PEMF
has been shown to accelerate the binding of calcium to calmodulin.
At the end of the 21 day period, one specific signal had the most
significant effect on wound repair, demonstrating a 59% increase in
wound tensile strength compared to control, leading researchers to
conclude that exposing wounds to PEMF of very specific
configurations accelerated wound repair in the early, most critical
phases of healing in this animal model. About Ivivi Technologies,
Inc. Based in Northvale, NJ, Ivivi Technologies, Inc. is a medical
technology company focusing on designing, developing and
commercializing its proprietary electrotherapeutic technology
platform. Ivivi�s research and development activities are focused
