简要总结
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.
详细描述
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.

结局指标
主要结局
Change from Baseline in Pressure pain threshold at 10 minutes after the intervention
时间窗: 10 minutes after the intervention
To obtain the pressure pain threshold measurements, an electronic pressure algometer was used. With the subject seated, the evaluator placed the pointer on the trigger pint with an approximate angle of 90º and an increasing pressure of approximately 1 kg/cm²/s. Subjects were told to use the word "now" whenever the sensation of pressure was replaced by a sensation of pain. At this point, the evaluator removed the algometer and the equipment recorded the maximum applied pressure.
Change from Baseline in Pressure pain threshold at 24 hours after the intervention
时间窗: 24 hours after the intervention
