LIV

Low-Intensity Vibration, or LIV for short, is a form of vibration with low force. LIV works as a mechanical stimuli on a microscopic level, where deformation occurs on cells and triggers a physiological process in the body. This process is called mechanotransduction. LIV can be generated by a device and be used to stimulate beneficial biological responses in the body.

Recent clinical studies show that LIV can be used to treat brittle-bone disease[1]. Recent smaller studies have shown that LIV shows a potential to treat non-healing wounds, i.e. wounds that per definition does not show significant healing within 30 days[2].

There are studies on the effect of LIV on wound healing in animals and on blood flow in humans. The results have been the following:

  • LIV increases blood flow by creating frictional forces on the inner walls of blood vessels, causing them to expand and allow more blood to pass. This is a natural reaction seen during exercise[3].
  • LIV reduces inflammation. Macrophage is a type of white blood cell known to be very important in the natural wound healing process. LIV changes its function from inflammatory to anti-inflammatory[4]. Neutrophils is another type of white blood cell that causes inflammation of the wound and is reduced by LIV[5][6].
  • LIV increases regeneration by increasing tissue growth and growth factors that help produce new blood vessels, skin cells, stem cells and the support structure of surrounding cells[7][8].
  • LIV reduces bacterial load by increasing macrophages accumulation[9].
  • LIV decreases blood glucose levels in diabetics by around 19%[10], contributing to countering the harmful effects of high blood sugar on the immune system and reduces the risk of infection[11].

Currently we are preparing for a clinical study to show the effectiveness of LIV in treatment of patients with grade 2 diabetic foot ulcers. If you are interested to know more to test the device yourself, please reach out to us.
