COVAS

CoVAS (Computerized Visual Analogue Scale) is a hardware accessory for use with the Pathway ATS and CHEPS, TSA2, Q-Sense, and AlgoMed systems. CoVAS offers computerized, real-time, continuous VAS evaluation – adding an important dimension to stimulus intensity measurements.

It can be used for continuous monitoring of response during experimental sessions, as well as measuring outcomes in pharmacological drug trials. The CoVAS allows high temporal resolution, and sensitive response to the stimuli offered. It can be a significant tool in monitoring and analyzing the reaction to tonic, or ultra-fast phasic pain stimuli.

A patient-controlled potentiometer, or slider, is utilized and the thermal stimulation and patient response curves are synchronized and available for export to a variety of spreadsheet programs for analysis. The CoVAS system comes with a USB connector to the computer.

CoVAS is also available in a special non-magnetic version for use in an fMRI environment. The hardware is modified to work inside the MRI exam room, connected via a long cable to the stimulator, located outside of the MRI room.
