Enrollment: 46
Sex: ALL
Minimum age (years): 18
Maximum age (years): 30
Standard ages: ADULT
Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Primary purpose: TREATMENT

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.


Eligibility criteria: Inclusion Criteria:

* Age between 18 and 30 years
* The presence of LTrP in the middle third of the upper trapezius muscle onthe dominant side
* Being able to provide written informed consent
* Being able to follow instructions and realize clinical tests

Exclusion Criteria:

* Any pharmacological therapeutic
* Any medical treatment or physical therapies at cervical region during the 6-month before this study
* Any diagnosed health problem
* Any history of head and upper extremity surgery or trauma
* Any red flags to DN, (ie: metabolic diseases, pregnancy, kinesiophobia,Infection, cancer)• Absence of recurrent history of neck pain
* No neck pain symptomatology the previous 6 months
* Cervical disk herniation

Primary outcomes:
measure: Changes in resting surface EMG activity (amplitude, RMS)
timeFrame: Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary outcomes:
measure: Changes in resting surface EMG activity (Median frequency, MF)
timeFrame: Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
measure: Changes in submaximal contrations surface EMG activity of upper trapezius (amplitude, RMS)
timeFrame: 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
measure: Changes in submaximal contrations surface EMG activity of upper trapezius (Median frequency, MF)
timeFrame: Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
measure: Change in Pain Pressure Threshold (PPT)
timeFrame: Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
