About this study

Official title: Mmediate and Short-Term Effects of Dry Needling, Percutaneous Neuromodulation, and Percutaneous Electrolysis on Muscle Tone and Pain: A Two-Phase Randomized Experimental Study in Healthy Subjects and Patients With Chronic Neck Pain.

Brief Summary:

This project consists of two sequential experimental phases designed to analyze the immediate and 24-hour effects of three invasive physiotherapy techniques -dry needling (DN), percutaneous neuromodulation (PENS), and percutaneous electrolysis (EPE)- on muscle tone and pain perception.

Read more

In the first phase, the study will be conducted on healthy volunteers to assess the physiological responses and safety profile of the interventions under controlled conditions. Each participant will receive one of the three randomly assigned interventions (DN, PENS, or EPE), applied to the upper trapezius muscle. Pain perception (Visual Analog Scale, VAS) and muscle mechanical properties (tone, stiffness, and elasticity) will be measured before and after the intervention, and after 24 hours, using the MyotonPRO device.

In the second phase, the same protocol and parameters will be applied to patients with chronic neck pain, in order to compare the magnitude and persistence of the effects between healthy subjects and symptomatic individuals.

This study aims to improve understanding of the short-term physiological mechanisms of invasive physiotherapy techniques and their relative effectiveness in managing chronic neck pain. The findings will contribute to the development of more precise and evidence-based treatment protocols for musculoskeletal pain.

Being tested
Dry needling, Percutaneous nerve stimulation, Percutaneous electrolysis

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dry needlingProcedure or surgery

    Dry needling will be performed on the upper trapezius muscle at an active myofascial trigger point. A sterile, single-use solid filament needle (0.30 × 40 mm) will be inserted until eliciting three local twitch responses (LTRs). The needle will then be withdrawn immediately after obtaining the final response. The technique aims to normalize motor endplate activity and reduce local and referred pain through mechanical and neurophysiological modulation.

  • Percutaneous nerve stimulationProcedure or surgery

    Percutaneous neuromodulation will be applied using a sterile acupuncture needle (0.30 × 40 mm) inserted near the accessory nerve pathway in the upper trapezius region. A low-frequency alternating current (10 Hz, 250 μs pulse width) will be delivered for 15 minutes using an electrotherapy device approved for clinical use. The objective is to modulate neuromuscular excitability and decrease pain perception through peripheral and central mechanisms.

  • Percutaneous electrolysisProcedure or surgery

    Percutaneous electrolysis will be performed by inserting a sterile acupuncture needle (0.30 × 40 mm) into the active myofascial trigger point of the upper trapezius. A galvanic current of 1 mA will be applied for three impacts of 5 seconds each using an approved electrolysis device. This technique produces a controlled local inflammatory response, promoting tissue regeneration and analgesia through electrochemical and neurophysiological effects.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain intensity

    Pain perception will be measured using a 10 cm Visual Analog Scale (VAS), where 0 indicates no pain and 10 indicates worst imaginable pain. Participants will mark their perceived pain intensity at rest. The scale is a reliable and validated tool for assessing subjective pain in musculoskeletal disorders.

    Measured: Baseline (pre-intervention), immediately post-intervention, and 24 hours post-intervention.

Secondary outcomes (3)
  1. Muscle tone

    Muscle tone will be assessed using the MyotonPRO device, which measures the natural oscillation frequency (Hz) of the muscle at rest. The upper trapezius will be evaluated at a standardized point corresponding to the active myofascial trigger point region. Higher frequency values indicate increased muscle tone.

    Measured: Baseline and immediately post-intervention, and 24 hours post-intervention

  2. Muslce stiffness

    Muscle stiffness will be evaluated using the MyotonPRO, which calculates the muscle's resistance to deformation expressed in newtons per meter (N/m). This parameter reflects the biomechanical rigidity of the tissue.

    Measured: Baseline, immediately post intervention and 24 hours post-intervention

  3. Muscle elasticity

    Elasticity will be measured with the MyotonPRO, expressed as the logarithmic decrement of the muscle's oscillation. Lower values indicate greater elasticity and better recovery capacity after deformation.

    Measured: Baseline, immedialely post intervention and 24 hours post intervention

Model description
This study is designed as a two-phase randomized experimental trial with parallel group assignment. In the first phase, healthy volunteers will be randomly assigned to one of three intervention groups: 1. Dry Needling (DN) - mechanical stimulation of an active myofascial trigger point in the upper trapezius. 2. Percutaneous Neuromodulation (PENS) - low-frequency electrical stimulation applied near the accessory nerve through an acupuncture needle. 3. Percutaneous Electrolysis (EPE) - galvanic current (1 mA, three impacts of 5 seconds) applied through a needle at the trigger point. All participants will undergo a single treatment session. Assessments of pain intensity (VAS) and muscle mechanical properties (tone, stiffness, elasticity measured by MyotonPRO) will be performed before the intervention, immediately after, and 24 hours later. In the second phase, the same study design, intervention parameters, and outcome measures will be applied to a population of patients with chroni

Who may be eligible to take part?

The sponsor lists 14 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain intensity (time frame: Baseline (pre-intervention), immediately post-intervention, and 24 hours post-intervention.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07345793, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Feb 2026; AzTrials last refreshed its copy on 7 Nov 2026.
