“CHEPS is an emerging and promising objective technique in clinical neurophysiology” says the 4th edition of the prestigious Clinical Neurophysiology, published by Oxford University Press (March 2016). The book includes a very useful chapter dedicated to the CHEPS by Medoc. It gives a thorough overview of the available methodologies contact heat evoked potentials (CHEPS) presents and its advantages.
The author, Dr. Benn E. Smith, affirms that having been used in individuals with a wide variety of peripheral and central disorders affecting spinothalamic pathways, CHEPS is an encouraging objective technique in clinical neurophysiology.
He also states that “contact heat evoked potential (CHEPS) testing is a validated method to study A delta- and C-fiber spinothalamic pathways from cutaneous afferents through the spinal cord and thalamus to the postcentral gyrus. With a rigorously collected published multinational set of normal values, CHEPS promises to be a valuable clinical and research tool to investigate small diameter nociceptive pathways in the periphery such as diabetic small fiber neuropathy as well as in central nervous system disorders affecting spinal cord and brain. As further data accumulate, the applications of CHEPS in clinical and research neurophysiology laboratories across the globe are likely to increase.”
Pathway Model CHEPS (Contact Heat-Evoked Potential Stimulator) is an advanced thermal stimulator for pain evoked-potentials equipped with functional MRI (fMRI) capabilities.
CHEPS is considered the most advanced and sophisticated device for pain assessment available today, and opens exciting opportunities in pain research.
