Thermal quantitative sensory testing (QST)
The TCS 2.2 uses Peltier-based contact thermodes and closed-loop temperature regulation. It supports warm and cold detection, thermal pain thresholds, temporal summation, CHEPs and CEPs.
- Independent temperature settings for multi-zone thermodes
- Real-time monitoring and automatic calibration
- Touchscreen operation or computer-driven sequences
- TTL synchronisation with electrophysiology acquisition
In thermal QST protocols, controlled temperature changes are paired with the participant’s reported detection or pain thresholds. Contact heat-evoked potentials (CHEPs) and cold-evoked potentials (CEPs) are separate applications using electrophysiological recordings.
See research publications using QST.Lab instruments and eVAS response measurement accessories.
