Pathway

Please note:

PATHWAY has been replaced by the new generation of QST devices.

 

Medoc’s new TSA2 provides a platform for different applications and thermode types. 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.

​

Both the TSA2 as well as the TSA2 Air devices with their standard 30*30 mm thermodes can match or even exceed the PATHWAY's previous rates for the ATS 30*30 mm thermode.

Technology and Capabilities for Pain & Sensory Evaluation

One of Medoc's PATHWAY Model

What is Pathway? 

​

Pathway – Pain & Sensory Evaluation System introduced revolutionary new technology and capabilities in the area of objective evoked pain potential and advanced stimulator products. These solutions had a modular design that could be tailored to specific needs and protocols and offered an easy upgrade path.

​

PATHWAY systems were available in two models:

​

What was PATHWAY model ATS? 

 

This configurable platform expanded on capabilities of the TSA-II NeuroSensory Analyzer, opening up exciting new possibilities for pain and peripheral nerve disease research, as well as for implementation in pharmaceutical development and clinical applications.

​

What was PATHWAY model CHEPS? 

 

PATHWAY model CHEPS made the evaluation of temporal summation (windup) possible, providing unique information regarding central pain processing mechanisms related to central sensitization. This information can be quite valuable in elucidating alterations of neurosensory processing and in documenting treatment effects.

Based on results conducted at a major US medical center with a leading pharmaceutical firm, PATHWAY model CHEPS has proven to evoke a definitive wave pattern corresponding with selective stimulation of A-delta and C-fibers. Contact Heat Evoked Potential Simulation (CHEPS), unlike laser stimulators, was able to elicit a C-fiber response. CHEPS technology provided much greater versatility in algorithm design and control, was easier and quicker to set up, and was a very cost-effective new option with superior benefits, as well as higher safety to patients and subjects.

fMRI PAIN PATHWAY for Pain Imaging

 

PATHWAY was a mobile system, mounted on a specially designed cart, containing the electronic base unit, heavy-duty integrated cooling unit, analog output, TTL input & output & Digital Calibration Kit as well as full fMRI conditional versions for pain imaging.

​

Additional Advantages

 

  • CHEPS – Objective & selective stimulation for electrophysiological via EEG recording of A-delta & C-fiber evoked pain potential

  • Rapid oscillation control for robust evaluation of Temporal Summation (Windup)

  • fMRI conditional for Pain imaging

  • Cold EP (available mid-2006)

  • Extreme cold pain stimulation (Down to 0 ºC)

  • Psychophysical testing for heating and cooling (e.g., ramp & hold, thresholds)
