In cryotherapy, mechanism of action could be classified into three stages: 1. heat transfer, 2. cell injury and 3. inflammation. Boiling point of liquid nitrogen is -196°C, which is the responsible for creating the initial stage which is heat transfer. The second stage is cell injury which is induced during thawing conditions of the cells.
