Summary

This case control study will investigate the physiological effect of nociceptive input in individuals with temporomandibular disorders. To do so, the investigators will compare the development of secondary hyperalgesia following high frequency electrical stimulation (HFS) of skin nociceptors in the forearms for up to 48 hours in individuals with chronic TMD (as a main complain) and in healthy controls. Furthermore, the investigators will evaluate the association between the response to HFS and various factors, such as demographic, psychosocial and pain-related clinical factors.

Conditions

  • Temporomandibular Disorder

Interventions

PROCEDURE

High-frequency electrical stimulation

High-frequency stimulation will be applied on the volar forearm (6-10 cm distal to the cubital fossa). To avoid any confounding effect of handedness, the arm onto which HFS will be applied twice (dominant vs nondominant) will be counterbalanced across participants. HFS will consist of 12 trains of 42 Hz electrical pulses lasting 1 s each. The time interval between each train will be 10 s. The intensity of stimulation will be milliampere. Electrical pulses will be delivered to the skin using a specifically-designed electrode designed: the cathode consists of 16 blunt stainless-steel pins with a diameter of 0.2 mm protruding 1 mm from the base. The 16 pins are placed in a circle with a diameter of 10 mm. The anode consists of a surrounding stainless-steel ring having an inner diameter of 22 mm and an outer diameter of 40 mm. This procedure induces secondary pinprick hyperalgesia (an increase in pinprick sensitivity in a large area of the skin).
