[Pain sensitivity in obese individuals].
Using the measure of the nociceptive threshold by saphenobicipital reflex method in 30 obese women (30 p. cent or more above ideal weight) and 20 controls, the authors observe that in the obese group the threshold of the nociceptive flexion reflex is significantly lower than in controls (6.57 +/- 3.52 mA in obese; 9.42 +/- 1.90 mA in controls). There is a significant reverse correlation between degree of overweight and the threshold of the nociceptive reflex. The authors suggest the hypothesis of an abnormality of the endogenous morphine-like system or of its control in human obesity.
