Latent Myofascial Trigger Point of Upper Trapezius Muscle Clinical Trial
Official title:
Short and Medium-term Effects of Manual Therapy on Latent Myofascial Pain : a Comparative Study
The purpose of this study was to investigate the short and medium-term effects of three manual techniques on cervical range of motion and pressure pain sensitivity in subjects with mechanical stress, presenting latent trigger point of upper trapezius muscle.
Myofascial pain syndrome is a common non-articular musculoskeletal chronic pain which has
not been yet fully understood. It is characterized by myofascial trigger point. This trigger
point is clinically classified as active or latent. Some studies have demonstrated the
potential relevance of latent trigger point. In fact, its presence may cause muscle
activation pattern alterations, increase nociceptive sensitivity and cause sympathetic
activity alterations. Nevertheless, the vast majority of individuals, even asymptomatic,
have latent trigger point. High prevalence of myofascial trigger points subsists at cervical
and scapular regions.
There is few data regarding myofascial trigger point physiopathology. Furthermore, a
diversity of therapeutic interventions consisting of trigger point inactivation and
interruption of the vicious cycle is suggested in literature. Nevertheless, the
effectiveness of these different interventions in trigger points and the duration of the
effects are not yet fully clarified.
