Ice is a common way to deal with pain and inflammation, and VibraCool uses technology to make that cooling treatment more effective. Not only is it a comfortable cold compress, but it also uses vibration to both expedite the benefits of cold therapy while also solving some of the inherent issues with cold treatment.
Icing muscles naturally decreases blood flow and stiffens muscles, so while it helps to reduce pain, it creates other issues. By adding a vibrating pack to the equation, VibraCool keeps blood flow up and prevents that long term stiffness.
VibraCool is based on the gate control theory for pain. The scientifically backed idea states that by adding sensations (like coolness or vibration) to a pain area, the brain will focus on those neutral sensations and "close the gate" to the pain signals.
