TSA-II - NeuroSensory Analyzer for Sensory Testing

An essential Quantitative Sensory Testing (QST) tool for evaluating nerve impairment and sensory testing 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 orvibration. The TSA-II sensory testing covers small-fiber testing (A-Delta and C-fiber), as well as for large caliber (A-Beta fibers) testing. The TSA-II is also used for identifying thermal pain thresholds in various clinical and research applications.


TSA thermal stimulator test procedure 

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. Sensory testing is performed by applying the TSA-II thermode 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.


A deviation from the normal range can indicate the existence of peripheral nerve disease or damage due to injury, illness or toxic exposure. Testing comparing contra-lateral body sites and longitudinal (or serial) evaluation before and after therapy can also be routinely employed.


Test result reports are generated in a variety of graphical formats. 


Dr. Martin Angst  from the department of anesthesia at Stanford University is using the TSA II for determining heat and mechanical pain threshold as described here.
