PATHWAY - Pain and sensory evaluation system
PATHWAY: the most advanced system for pain and sensory evaluation.
The PATHWAY System is a mobile, configurable platform that can be used for pain and peripheral nerve disease research, pharmaceutical development and clinical applications. PATHWAY systems are available in three versions : PATHWAY Model CHEPS , PATHWAY Model ATS and PATHWAY combined CHEPS/ATS. Functionalities common to all PATHWAY models:
-
Quantitative sensory testing (QST)
-
determination of cold and heat sensation and pain thresholds
-
temporal summation (Windup) through rapid oscillation control
-
psychophysical testing for heating and cooling
-
evaluation of patient's subjective response (via push button or computerized visual analogue scale - CoVAS)
-
automatic comparison of test results to normative reference data
-
mobile trolley
-
Analog output and TTL input and output for connection to external systems (EEG, MRI, controlling computer...)
Functionalities available exclusively on PATHWAY model CHEPS (Contact Heat- Evoked Potential Stimulator):
-
Contact Heat Evoked Potentials: objective and selective stimulation of A-delta & C-fiber to record evoked pain potential on an external EEG/EP system.
-
Cold Evoked Potentials
-
optional MRI-compatible CHEPS thermodes
Functionalities available exclusively on PATHWAY model ATS (Advanced Thermal Stimulator):
-
Quantitative sensory testing (QST)
-
Extreme cold pain stimulation (Down to minus 10ºC)
-
optional MRI-compatible ATS thermodes
PATHWAY combined CHEPS/ATS gathers all these functionalities in a single system.
