The Effects of Noxious Electrical Stimulation and Eccentric Exercise on Mechanical and Thermal Pain Sensitivity in Recreational Runners with Achilles Tendinopathy.

Background: Achilles tendinopathy is a common overuse condition that can become persistent despite conservative treatment. Sensitization of both the peripheral and central nervous systems may contribute to the persistent pain. Both exercise and electrical stimulation have the potential to modulate the nervous system's sensitivity to painful stimuli.
