Inclusion Criteria

Age between 18 and 35 years old; persistent pain in the upper trapezius region for more than 6 months; presence of active or latent MTP (myofascial trigger points) in the upper trapezius muscle to be confirmed with palpation and digital pressure; analog visual scale above 5 in the trapezius region

Primary Outcome Measures

Name	Time	Method
Pain intensity assessment will be obtained through the Visual Analog Scale (VAS), a one-dimensional instrument for pain intensity assessment. This is a 10 cm horizontal line with the ends numbered 0 and 10. At one end of the line is marked no pain” (close to 0) and at the other worst imaginable pain”. The patient is then asked to assess and mark the pain present at that moment on the line. With the help of a ruler, the distance between the individual's marking and the lower end is measured, on a scale in centimeters.

Secondary Outcome Measures

Name	Time	Method
The pressure pain threshold will be measured using an algometer (Digital Manual Dynamometer), model DDK/20 (Kratos Equipamentos Industriais - Kratos®), a device that records the intensity of pressure exerted on a given surface of the body when the individual reports sensation of pain at the application site (digital reading). The device contains a bar with a flat circular tip of 1.0 cm² in diameter, with a precision of 0.005 kg, which will be used to apply pressure on the upper trapezius muscle, with a speed of 1 cm/s, until the volunteers report a sensation of pain. , the value being fixed on the instrument display and noted. The evaluation will be carried out with the volunteers positioned in dorsal decubitus, keeping the head slightly rotated to the contralateral side to the evaluated one. Lower values indicate a lower pain threshold and before application to a new point, the examiner will reset the display measurement.
