Brief Summary:
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.

Arm Intervention/treatment
Experimental: Dry Needling of trigger point
Deep dry needling will be applied on the upper trapezius myofascial trigger point
Other: Dry needling
Deep dry needling until achieving twitch response of the muscle

Experimental: Strain-counterstraing technique
This manual technique will be applied at the upper trapezius.
Other: Strain-counterstrain technique
A manual technique to release tension of painful muscles.

Placebo Comparator: Placebo manual technique
A technique simulating strain-counterstrain, but without any therapeutic manoeuvre will be applied at the upper trapezius site.
Other: Placebo manual technique
A placebo technique, consisting of manual contact of the therapist with the patient without any further therapeutic approach

Primary Outcome Measures :
  1. Pain Pressure Threshold [ Time Frame: 6 sessions ]
    Amount of pressure (Kg/cm2) applied at the myofascial trigger point site that elicit pain for the patient will be reported. Analogy pressure algometer(Wagner, FPK 20) will be used.

Secondary Outcome Measures :
  1. Pain at rest [ Time Frame: 6 sessions ]
    Visual Analogue Scale

  2. Neck Disability [ Time Frame: 6 sessions ]
    Neck Disability Index

  3. Electromyographic activity of the upper trapezius [ Time Frame: 6 sessions ]
    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.
