The Latest Advance in Thermal Pain Stimulation from Madoc – TSA2

The Latest Advance in Thermal Pain Stimulation

 Quantitative Sensory Testing (QST) is a valuable method for diagnosing peripheral nervous system disorders, including chronic pain and pain related to various diseases, such as Diabetes and CRPS. QST essentially determines the sensation and pain thresholds for cold and warm temperatures, and the vibration sensation threshold by stimulating the skin and comparing the results to normative values built in the software. When the stimulus activates stimuli-specific receptors; the nerve fibers that innervate the receptors communicate the stimuli message to the central nervous system, where feeling occurs.

The TSA2 System is the latest advance in Thermal Pain Stimulation; offering enhanced precision in a robust, portable device.
New software capabilities offer a tool for static and dynamic QST, as well as the most sophisticated of research protocols, run from external platforms.
