Infrared thermography in evaluation of myofascial trigger points in the shoulder pathologies

Abstract

Myofascial trigger points (TrPts) are tense, palpable bands. They can arise spontaneously or as a result of mechanical stimuli, and are capable of setting off local pain that is reported by subjects in proximal or distant areas. Objective: This study aimed to analyze the incidence, sensitivity and localization of the TrPts in patients with clinic diagnosis of bursitis and shoulder tendinitis by means of infrared thermography. Method: Eleven subjects with mean age of 40.8 (11.5) years were assessed using algometry and thermography. Results: All subjects showed myofascial trigger points in some muscles, as upper trapezius, levator scapulae, supraspinatus, infraspinatus and rhomboids. Conclusion: It was possible to verify the relevance of infrared thermography as a complementary component in the myofascial trigger points assessment.
