MYOFASCIAL PAIN SYNDROMES - CLINICAL AND PATHOPHYSIOLOGICAL ASPECTS

The criteria for performing a diagnosis of myofascial pain syndromes caused by trigger points (TrPs) are defined and the clinical features of pain and related phenomena due to these syndromes are examined together with the sensory modifications of the parietal tissues at TrPs and target level in the case of both active and latent TrPs. The factors presumably responsible for the occurrence of TrPs in myofascial structures are then considered, with particular emphasis on the microtraumatic event caused by biomechanical alterations during movement, evaluated by the analysis of the ground-foot reaction. With this respect, some examples of myofascial pain syndromes of the lower limbs are reported in which the correction of these alterations, performed via dynamic orthosis, produces a long-lasting remission of the subjective and objective symptomatology.
