Effect of Dry Needling on Surface Electromyographic Activity in Latent Trigger Points

Effect of Dry Needling on Surface Electromyographic Activity in Latent Trigger Points

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.

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
