What is QST?
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’s message to the central nervous system, where feeling occurs.
Why QST?
Quantitative Sensory Testing is a non-invasive, pain-free technique that can assist in early detection, therapy selection and monitoring the progression and recovery of patients with peripheral sensory disorders
The diagnostic power of Quantitative Sensory Testing as a tool in diagnosing peripheral nervous systems disorders is a unique combination of instrumentation and technology, integrated with robust software and mission-specific hardware. When packaged in application-specific systems and configurations based on varying sensory modalities, and different body locations for specific medical or research needs, QST systems are valuable elements in medical research and treatment. This integration and packaging is the foundation of all Medoc’s products and systems.
