Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

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

Group Type ACTIVE_COMPARATOR

Dry Needling in upper trapezius

Intervention Type OTHER

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

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

Group Type EXPERIMENTAL

Dry Needling in lower trapezius

Intervention Type OTHER

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.
