Description

Laser stimulator

Technical Field

The invention relates to the technical field of stimulators, in particular to a laser stimulator.

Background

In the field of neurophysiology, the introduction of laser stimulators has revolutionized the research approach to pain. Two types of methods, current stimulation and thermal stimulation, have been conventionally used. Since large diameter nerve fibers have a lower current threshold than those small nerve fibers that transmit pain, the current stimulus also activates these large non-pain nerves, thereby inhibiting or retarding the generation and conduction of pain signals. This requires selective activation of pain receptors. Although conventional thermal stimulation approaches can selectively activate pain receptors, the process is too slow to produce synchronous afferent nerve activity due to the rise in skin temperature. Specifically, the first method is thermal conduction, which can control the stimulation temperature, but it affects the accuracy of the data because it needs to contact with the skin to stimulate mechanoreceptor; the second method is heat radiation, which avoids the problems associated with skin contact, but it is difficult to accurately control the stimulation temperature. Stimulation of the pain nerve by laser is a major breakthrough in research methods in this field because there are no problems with other conventional methods, and smooth or hairy skin can be better detected. Compared with other methods which can only detect nerve density, laser stimulation can distinguish different sensory nerves such as A- (pain sensation) and C (heat sensation), for example, the DeKA-next laser stimulator Stimul 1340 for pain sensation research has the principle that the function of detecting the central nervous system is achieved by stimulating the A-and C nerves, and the laser does not need to contact the skin, so that the tactile sensory nerves can not be stimulated.
