Pain Gate

In 1965, psychologist Ronald Melzac and neuroscientist Patrick Wall proposed a widely accepted theory of pain - the pain gate control theory. This theory suggests that the transmission of nerve impulses related to pain is regulated by the "gate" mechanism of spinal gray matter, which is influenced by the balance of activity between coarse and fine nerve fibers. Fine nerve fibers promote the conduction process (like opening a gate), while coarse nerve fibers inhibit the conduction process (like closing a gate). Meanwhile, this theory suggests that the gate mechanism that determines the behavioral and experiential characteristics of pain is regulated by internal brain processes.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Pain is a self-protection mechanism in the human body that sends signals from the nervous system to the brain, informing us of potential danger or injury to the body. But in some cases, we may experience unnecessary pain or the pain may become too intense, which can have a serious impact on our physical and mental health.
