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

Not Applicable

Completed

• Conditions: Trigger Point Pain, Myofascial
• Interventions: Device: Control-Dry Needling; Device: Intervention-Dry Needling

• Registration Number: NCT04684784
• Lead Sponsor: University of Castilla-La Mancha

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.

Arm && Interventions

Group	Intervention	Description
Sham Dry Needling	Control-Dry Needling	Control-Dry Needling: Sham Dry Needling into the latent trigger point of the upper trapezius muscle
Deep Dry Needling	Intervention-Dry Needling	Intervention-Dry Needling: Deep Dry Needing into the latent trigger point of the upper trapezius muscle

Primary Outcome Measures

Name	Time	Method
Changes in resting surface EMG activity (amplitude, RMS)	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 Outcome Measures

Name	Time	Method
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	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).; EMG median frequency will be used to determine the endurance of the upper trapezius. The EMG median frequency will be measured in Hertz (Hz).
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	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).; EMG activity of submaximal contractions will be expressed as a percentage of submaximal reference contractions of the upper trapezius (% reference contractions).
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	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).; EMG median frequency will be used to determine the endurance of the upper trapezius. The EMG median frequency will be measured in Hertz (Hz).
Change in Pain Pressure Threshold (PPT)	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment	Pressure-Pain Threshold as assessed by an manual mechanical algometer. PPT is the minimal amount of pressure that produces pain and is used to assess abnormalities in nociceptive processing or hyperalgesia.
