The Hargreaves test is one of the classic experiments used to detect thermal pain responses in rodents. The test is commonly used to quantify the thermal threshold to radiation or infrared thermal stimulation in the hind paw of mice and rats. In the Hargreaves test, a radiant or infrared heat source is usually placed underneath the rodent and aimed at the plantar surface of the rodent's hind ...
Abstract Background. Peripheral nerve injury can result in the formation of neuroma/nerve entrapment, a persistent peripheral neuropathic pain state which is often refractory to invasive interventions or medications. Therefore, there is a need in the field of pain management to develop innovative noninvasive therapy in treating post-traumatic peripheral neuropathic pain states. A new ...
INTRODUCTION After a peripheral nerve injury, fast conducting large myelinated afferent A-bcta fiber transmission diminishes over time. On the other hand, firing of smaller pain transmitting fibers such as A-dclta and C-fibcrs is enhanced. This aberrant afferent neuronal behavior is thought to be one of the main neuronal mechanisms leading to development of chronic posttraumatic peripheral ...
