TSA-II – NeuroSensory Analyzer

An essential Quantitative Sensory Testing (QST) tool for evaluating nerve impairment in clinical, research and pharmacological trial settings 

The TSA-II NeuroSensory Analyzer is a precise, computer-controlled device capable of generating and documenting response to highly repeatable thermal and vibratory stimuli, such as warmth, cold, heat-induced pain, cold-induced pain or vibration.

The TSA-II delivers quantitative assessment of small-caliber (A-Delta and C-fiber) sensory nerve function, as well as for large caliber A-Beta fibers. The TSA-II is also used for identifying thermal pain thresholds in various clinical and research applications.The test procedure itself is similar to that employed in such routine tests as eye and hearing examinations, where patients are asked to respond to visual or auditory stimuli.

The TSA-II thermode is placed on the patient’s skin to heat or cool the skin. Patients respond to the temperature stimuli by pushing a button, and the sensory threshold is recorded and automatically compared to an age-matched normative data.
