The purpose of this study was to measure the nociceptive threshold in hypothyroid patients by determining when the nociceptive flexion reflex of the lower limb occurs under percutaneous electrical stimulation of the sural nerve, given that this threshold is well correlated with pain sensation. Twelve hypothyroid patients and twelve control subjects participated in the study. In the case of the hypothyroid patients, the nociceptive flexion reflex (or RIII reflex) was measured before and six weeks after the onset of substitution treatment. The results clearly indicate that the nociceptive threshold of the patients with hypothyroidism was significantly higher than that of the control subjects. After six weeks of substitution treatment, the RII threshold return to normal. The analgesia observed in the hypothyroid patients in this study do not appear to be correlated with the blood TSH level. The possible mechanisms of these analgesic effects are discussed.

UI	MeSH Term	Description	Entries
D007037	Hypothyroidism	A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA. It may be primary or secondary due to other pituitary disease, or hypothalamic dysfunction.

D009619	Nociceptors	Peripheral AFFERENT NEURONS which are sensitive to injuries or pain, usually caused by extreme thermal exposures, mechanical forces, or other noxious stimuli. Their cell bodies reside in the DORSAL ROOT GANGLIA. Their peripheral terminals (NERVE ENDINGS) innervate target tissues and transduce noxious stimuli via axons to the CENTRAL NERVOUS SYSTEM.
