Hypothesis The application of intramuscular electrostimulation will be more effectiveness than the dry needling in myofascial trigger points treatment.
Objetives:
To determine the effectiveness of intramuscular electrostimulation in the treatment of trigger points of the levator scapula muscle for the improvement of pain in mechanical cervicalgia.
Participants: Subjects with diagnosed of myofascial pain syndrome in cervical region and active trigger points in levator scapulae muscle, randomly assigned to experimental or control group.
Intervention: Control group: one session of dry needling in active trigger points; experimental group: one session of intramuscular stimulation in active trigger points.
Main Outcomes Measures: Pain, pressure pain threshold (PPT), active cervical range of motion and strength muscle . The measures will be taken before, after and one week after the interventions.
The muscle pain is one of the most common forms of musculoskeletal pain. Within muscular pain, the presence of myofascial trigger points (PG) in the musculature is a important and prevalent problem.
Currently one the techniques most used in the treatment of PG is dry needling. Dry needling has been shown effective in the treatment of neck pain associated with PGs.
To our knowledge, there are no studies that they have compared the effectiveness of dry needling and intramuscular stimulation by applying an electric current.
This study is a randomized clinical trial that aims to demonstrate that the application of an electric current associated with dry needling in the treatment of PG.
In this study we will treat subjects with cervical pain who they have active PGs in the levator scapulae muscle.

| Pain Visual Analogue Scale | The pain VAS is a unidimensional measure of pain intensity, which has been widely used in diverse adult populations. The VAS is a straight horizontal line of fixed length, usually 100 mm. The ends are defined as the extreme limits of the parameter to be measured from 0 (no pain) to 10 (maximum pain). All the subjects will showed their pain level. | Change from baseline at one week |
