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.

Treatment and study plan

Intervention-Dry Needling

Device

Deep Dry Needling into the site of the latent TriggerPoint of the upper trapezius muscle. 1 session in upper trapezius muscle moving the needle up and down ten times.

Control-Dry Needling

Device

Sham Dry Needling into the site of the latent Trigger Point of the upper trapezius muscle with non-penetrating needles

Primary outcomes

  1. 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

  1. Changes in resting surface EMG activity (Median frequency, MF)

    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).

    EMG median frequency will be used to determine the endurance of the upper trapezius. The EMG median frequency will be measured in Hertz (Hz).

  2. Changes in submaximal contrations surface EMG activity of upper trapezius (amplitude, RMS)

    Time frame: 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).

  3. Changes in submaximal contrations surface EMG activity of upper trapezius (Median frequency, MF)

    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).

    EMG median frequency will be used to determine the endurance of the upper trapezius. The EMG median frequency will be measured in Hertz (Hz).

  4. Change in Pain Pressure Threshold (PPT)

    Time frame: 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.
