Dry needlin is a manual therapy technique used for miofascuial pain syndrom treatment. The patient will be supine, in a confortable position. The therapist localizes the trapezius trigger point number 2 and then performes the needling until 2 REL are obtenined. The patient will remain supine during 15 minutes.

Visual Analogue Scale (VAS) is a subjective evaluation. There are previous studies that demonstrate its reliability and its sensitivity, wich give validity to VAS messures. The messure is made using a two sides 10 centimeters scale. The patient´s face shows an increasing slope that allows the patient to mark his pain level. That mark has his equivalent number on the scale, so 0 is no pain and 10 is maximum pain. A differece of 2 points on the scale means the minimum clinically significant change.

To messure the cervical range of movement, a CROM will be used. The CROM is a special goniometer that allows therapists to messure cervical movements. It conists on trhee pairs of inclinometers that allow reserchers to messure range of flexion-extension, lateral flexion and rotation. The CROM has a porved reliability, providing a inter-meter reliability from 0,7 to 0,9 and an intra-meter reliability from 0,8 to 0,87. The patient will be seated on a cheir, and he´ll perform cervical movements actively, just untill he starts to feel his pain. Each movement will be messure three times, and the average will be taken.
