Background
Pain is one of the most common clinical symptoms, is associated with a variety of diseases, and affects the course of the disease and the clinical therapeutic effect. Pain affects the mind and mind of the patient. The pain threshold determination is a common method for pain research, and accurate and objective measurement of the pain threshold plays an important role in diagnosis of diseases, evaluation of treatment effects and judgment of prognosis. Mechanical pain refers to the mechanical deformation of tissue under the action of external force, and when the deformation degree exceeds the threshold value of mechanical nociceptors, the nociceptors are activated to generate mechanical pain. After the external force is removed, the tissue is reshaped and the pain disappears. In basic studies of pain, one of the main methods for determining the behavior of model animals includes heat-induced pain, touch-induced pain, and the like. Mechanical pain determination mainly adopts von-Frey (von Frey membranes) cilia at present, and the principle is to use cilia with different specifications to stimulate repeatedly for many times and observe the occurrence of hyperalgesia of animals after inflammation or nerve injury.
