Why the study?
Does repetitive noxious heat stimulation at a fixed location compared to variable locations alter heat pain perception and evoked potentials in volunteers?
Does repetitive noxious heat stimulation at a fixed location compared to variable locations alter heat pain perception and evoked potentials in volunteers?
Human heat pain perception and contact-heat EPs display rapid habituation when stimulation is restricted to a fixed location, reflecting fatigue of peripheral nociceptive neurons.
No takes yet. Share an insight, caveat, or question.
Fixed-location heat may accelerate habituation in pain experiments; leaves open effects on clinical nociceptive testing protocols.
Greffrath et al. (2007) studied this question.
