Optional Accessory of the TSA-II
CoVAS is a hardware/software accessory of the TSA-II NeuroSensory Analyzer, offering computerized, real-time, continuous VAS evaluation. Computerized VAS provides an additional dimension beyond pain threshold measurements. It is a tool for continuous monitoring of response during therapeutic and experimental sessions, as well as an outcome measurement tool for drug trials. A patient-controlled potentiometer or slider is utilized while the TSA-II generates a variety of thermal stimulation protocols selected and programmed by the user (See TPS below). The thermal stimulation and patient response curves are synchronized and available for export to a variety of spread sheet programs for analysis.

Software platform for the CoVAS
The Thermal Pain Stimulator (TPS) is serving as the software platform of the CoVAS, offering single or successive sequences of ramping stimulations.

Special Non-Magnetic CoVAS for fMRI Applications
The CoVAS is also available in a Non-Magnetic version for use in the Functional MRI environment. In this configuration, the CoVAS Hardware is modified to work inside the MRI room. It is connected by a long cable to the TSA-II, which is located outside of the MRI room.
