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

February 18, 2021 updated by: University of Castilla-La Mancha
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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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).
Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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).
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)
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).
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

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.
