Abstract

Physical exercise may produce hypoalgesic effects, a property known as hypoalgesia induced by physical exercise. This concept is applied as adjunctive therapy for many chronic pain conditions, including recurrent orofacial pain. The main objective of this study will be to evaluate the influence of the level of physical activity, measured by means of the modified International Physical Activity Questionnaire (IPAQ), on the perception and modulation of orofacial pain. Ninety healthy participants aged 18-50 years will be classified according to the intensity and frequency of physical activity, based on IPAQ and will be divided into very active (15 men and 15 women) moderately active (15 men and 15 women) and insufficiently and / or sedentary (15 men and 15 women). 30 patients with chronic temporomandibular dysfunction will be part of the experimental group. The somatosensory characteristics related to pain perception and pain modulation will be evaluated by the mechanical pain threshold (MPT), temporal summation test (WUR), pressure pain threshold (PPT) and pain modulation conditioning test (CPM), respectively. The psychosocial characteristics and behavioural analysis will be done by the State Trait Anxiety Inventory (IDATE), Catastrophic Thoughts Scale, Pittsburgh Sleep Quality Index, SF-36 generic quality of life assessment questionnaire, and the "Fantastic Lifestyle" Questionnaire. The data will be submitted to statistical analysis through multivariate analysis of variance (ANOVA) and multiple linear regression. A 5% level of significance will be adopted. (AU)
