Overview
Brief Summary
Brief summary: The purpose of this study is to determine the effect of Dry Needling (DN) on electromyographic activity in different situations at the latent trigger point (LTrP) point of the upper trapezius. Randomized controlled trial, in parallel with the crossover control design. Two groups with LTrP in the upper trapezius, and the DN group or the Sham-Dn group will be randomly selected.

Outcomes
Primary Outcomes
Changes in resting surface EMG activity (amplitude, RMS)
Time Frame: Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
EMG activity (RMS) of the upper trapezius after dry needling or sham needling as assessed by the EMG ME 6000 TE(Mega Electronics, Kuopio, Finland). Resting EMG activity will be expressed as a percentage of maximal reference contractions of the upper trapezius (% reference contractions).
Secondary Outcomes
- Changes in resting surface EMG activity (Median frequency, MF)(Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment)
- Changes in submaximal contrations surface EMG activity of upper trapezius (amplitude, RMS)(Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 7submaximal contractions EMG activity will be expressed as a percentage of maximal reference contractions of the upper trapezius (% reference contractions).2 hours after treatment)
- Changes in submaximal contrations surface EMG activity of upper trapezius (Median frequency, MF)(Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment)
- Change in Pain Pressure Threshold (PPT)(Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment)
