This study investigates the effect of two different techniques (dry needling and Strain-counterstrain manual technique) on the upper trapezius myofascial trigger point (MTP). Subjects with active or latent MTP in this location of the muscle will be identified and will be randomly assigned to one out of three groups: dry needling, strain-counterstrain or placebo manual technique. Pain pressure threshold, provoked pain, pain at rest, neck disability and electromyography (EMG) activity of the upper trapezius will be registered before and after six sessions of treatment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Dry Needling of trigger point | Experimental | Deep dry needling will be applied on the upper trapezius myofascial trigger point |
|
| Strain-counterstraing technique | Experimental | This manual technique will be applied at the upper trapezius. |
|
| Placebo manual technique | Placebo Comparator | A technique simulating strain-counterstrain, but without any therapeutic manoeuvre will be applied at the upper trapezius site. |
|
| Name | Type | Description | Arm Group Labels | Other Names |

| Electromyographic activity of the upper trapezius | Surface EMG will be recorded (MP 100 de BIOPAC Systems; Goleta, California, USA). Electrodes will be located to register activity of the Upper trapezius, according to Surface ElectroMyoGraphy for the Non-Invasive Assessment of Muscles (SENIAM) guidelines. Microvolts of activity at rest will be recorded. Data will be normalized through calculation of maximal voluntary contraction, so that final data will be reported as a percentage. | 6 sessions |
