About

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.

Full 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.

24 participants in 2 patient groups

Dry needling in upper trapezius

Active Comparator group

Description:

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

Treatment:

Other: Dry Needling in upper trapezius

Dry needling in lower trapezius

Experimental group

Description:

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

Treatment:

Other: Dry Needling in lower trapezius
