El CHEPS
(Contact Heat-Evoked Potential Stimulator)
es un avanzado estimulador térmico para el
potenciales evocado de dolor equipado con capacidad de imagen por resonancia magnética funcional (fMRI). Se utiliza en combinación con sistemas de grabación de EEG, CHEPS documentar la respuesta tiene como objetivo a la percepción del dolor investigando térmica y nociceptivos trazados que median la percepción sensorial humana y dolor. |

Advancing toward an objective assessment of pain |
|
|
|
|
The CHEPS (Contact Heat-Evoked Potential Stimulator) is an advanced thermal stimulator for pain evoked-potential equipped with functional MRI (fMRI) capabilities. Used together with EEG recording systems, CHEPS documents objective response to pain perception by investigating human thermal and nociceptive
pathways that mediate
sensory and pain perception. This is achieved via selective stimulation and identification of A-Delta & C-fibers through EEG signal waveform recording. |
|
|
|
|
|
|
|
|
|
CHEPS is considered the
most advanced and sophisticated device for pain assessment available
today, and is opening an exciting opportunities in pain research.
Documenting and measuring objective response to evoked-pain is
important in clinical and research applications, such as assessing
pain associated with medications and treatments. |

Through rapid and
precise thermal stimulation oscillation control, PATHWAY
model CHEPS enables
the evaluation of temporal summation / Windup, providing unique
information regarding central pain processing mechanisms related to
central sensitization. |

Technological
breakthrough |
|
|
|
|
The
CHEPS system deploys an
extremely rapid heating rate of 70°C/sec and cooling rate of 40°C/sec
, to deliver pain stimuli within temperature range of 30°C to 55°C
in less than 300 milliseconds. This rapid heating is possible due to Medoc’s new 27mm diameter thermode and thermal stimulator which
enable testing large skin areas to reach greater receptor fields.
The
CHEPS system is equipped
with newly developed heat-foil technology, combined with solid-state
thermoelectric cooler (Peltier elements), as well as powerful
temperature controlled algorithms. |

PATHWAY CHEPS is also available in an fMRI safe configuration. CHEPS
Thermode can be used to deliver thermal stimuli inside fMRI
scanners. By using a special fMRI filter, the PATHWAY system ensures
accurate stimulation and reduced imaging artifacts. |
