The TSA-II NeuroSensory Analyzer is the essential
tool for evaluation of nerve impairment in clinical practice,
research and pharmacological trial settings. Quantitative
Sensory Testing (QST) of the thermal modalities is the
only clinical test for quantitative assessment of small-caliber
(A-Delta and C-fiber) sensory nerve function, the primary
transmitters of pain sensation.
Principle of Operation
The TSA-II NeuroSensory Analyzer is a precise,
computer-controlled device capable of generating and recording a
response to a highly repeatable thermal (and vibratory) stimuli,
i.e., warmth, cold, heat-induced pain or cold-induced pain. The
test procedure itself is similar to that employed in such routine
tests as eye and hearing examinations, where the patient is asked
to respond to a visual or auditory stimuli.
Utilizing a device called a "thermode" which is placed
on the patient's skin, the TSA-II is capable of
heating or cooling the skin as needed. The patient is asked to
respond to these temperature stimuli by pushing a response button.
A sensory threshold is recorded and compared to an age-matched
normal population value by the computer. A deviation from the
normal range can indicate the existence of peripheral nerve
disease or damage due to injury or toxic exposure. Testing
comparing contra-lateral body sites and longitudinal (or serial)
evaluation before and after therapy are also routinely employed. A
test result printout provided and is available in a variety of
graphical formats, i.e., Single
Test Result, Contralateral
Comparison, Outcome
