TSA-II / TSA-2001 - a Previous Product
Previous Product | Please note:
TSA-II / TSA-2001 are no longer produced and have been replaced by the new generation of QST devices.
Medoc’s new TSA2 provides a platform for different applications and thermode types, including 30*30 mm,
16*16 mm, CHEPS, Intraoral, 30*30 fMRI, 16*16 fMRI, CHEPS fMRI.
The TSA2 CHEPS thermode enables contact heat evoked potentials, as well as cold evoked potentials to very low temperatures.
For users interested in high speeds for paradigms such as Temporal Summation, Virtual Reality, or for use in the fMRI; the TSA2 CHEPS and TSA2 CHEPS fMRI thermode would serve you well.
​
The TSA2 Air device is an air-cooled version of the previous TSA-II, equipped to handle standard QST and more, matching TSA-II's previous specifications with the 30*30 mm thermode. ​
TSA-II NeuroSensory Analyzer
Medoc's original thermal QST platform, built to evaluate small sensory nerve fiber function, and pain.
​What was the TSA-II?
The TSA-II NeuroSensory Analyzer was Medoc's thermal quantitative sensory testing (QST) system for evaluating small-caliber (A‑delta and C‑fiber) sensory nerve function. A Peltier-driven thermode delivered precisely controlled warm, cold, and heat-pain stimuli to the skin, while its Windows-based software ran Limits, Levels, and Manual test paradigms and scored results automatically against normative reference data.
Paired with the optional CoVAS (Computerized Visual Analog Scale) unit, it also captured a subject's real-time pain rating alongside the temperature trace, and later in its life it supported fMRI-conditional configurations for pain-imaging research.
It was FDA cleared and CE marked (Notified Body 1282), and it was used across clinical neurology, pain medicine, and pharmaceutical trial settings.
Backed by a deep body of published research
Few QST instruments accumulated as extensive a research record as the TSA-II. Its predecessor, the TSA 2001, is frequently conflated with it in author citations — between the two, the literature attributed to this device lineage surpasses 1,000 references, spanning pediatric normative data, small-fiber and diabetic neuropathy, and complex regional pain syndrome.
