Brief Summary:
The aim of this study is to compare the surface electromyography (EGM) changes between dry needling in the upper trapezius, is a prevalence tonic fiber or lower trapezius is a prevalence phasic fiber.

Condition or disease Intervention/treatment Phase
Muscle Disorder Trigger Point Pain, Myofascial Other: Dry Needling in upper trapezius Other: Dry Needling in lower trapezius Not Applicable

Detailed Description:

Several studies already found a disturbed surface electromyography activity in myalgic muscle tissue and in the vicinity of myofascial trigger points, however studies about the effect of dry needling in this fibers type on these disturbances in EMG activity are scarce.

The surface electromyography of upper trapezius is related with a tonic muscle dysfunction, for example muscle contracture; and the lower fiber of trapezius is related with atrophy muscle.

Dry needling is an effective method for the treatment of myofascial trigger points for immediate reduction of pain. There are some studies about latent myofascial trigger point and motor activity, but we don't know any research about the effect of dry needling in the differences fibers.

Arm Intervention/treatment
Active Comparator: Dry needling in upper trapezius
Patients receive dry needling in latent myofascial trigger point in upper trapezius. The needle was penetrated into the muscle fibers of the taut band and was moved upward and downward ("fast in, fast out") in different directions with the aim to elicit LTRs
 Other: Dry Needling in upper trapezius

The following criteria are required for a patient to have latent TrPs: the presence of a palpable taut band in the upper trapezius muscle, the presence of a hypersensitive spot in the taut band, a palpable or visible local twitch on snapping palpation, and a no familiar reproduction of referred pain elicited by palpation of the sensitive spot.

Dry needling is performed with solid filiform needles (0.30x30 mm), these needles are sterile and separately packaged. Needles are not reused and are immediately deposited in a needle container after usage. Patients receive dry needling in latent myofascial trigger point (LTRs) in upper trapezius. The needle is penetrated into the muscle fibers of the taut band and was moved upward and downward ("fast in, fast out") in different directions with the aim to elicit LTRs
Experimental: Dry needling in lower trapezius
Patients receive dry needling in latent myofascial trigger point in lower trapezius. The needle was penetrated into the muscle fibers of the taut band and was moved upward and downward ("fast in, fast out") in different directions with the aim to elicit LTRs
 Other: Dry Needling in lower trapezius

The following criteria are required for a patient to have latent TrPs: the presence of a palpable taut band in the lower trapezius muscle, the presence of a hypersensitive spot in the taut band, a palpable or visible local twitch on snapping palpation, and a no familiar reproduction of referred pain elicited by palpation of the sensitive spot.
