Study summary

Headache is a very frequent symptom among the world population, the adult population with an active headache disorder are 46% for headache in general, 11% for migraine, 42% for tension-type headache and 3% for chronic daily headache. There are different therapeutic approaches for the improvement of headache. Transcutaneous stimulation of the auricular vagal nerve is being used for the treatment of headache due to the involvement of the vagus nerve in inflammation and pain modulation. On the other hand, galvanic current has shown a measurable effect by increasing parasympathetic activity. The objective of this clinical trial is to stimulate the auricular vagal nerve with galvanic current using a needle as an electrode that will be inserted into the concha of the ear. As a tool for measuring results, infrared thermography will be used to observe changes in facial skin temperature, since patients with high sympathetic activity present a characteristic pattern of "cold nose" and/or "cold patch". In addition, variables that record changes in autonomic activity such as skin conductance and heart rate variability will be collected.

Study arms

  • Experimental
    Pecutaneous electrolysis group

    Subjects were treated twice (one day and one week). The technique consisted in the application of a galvanic electrical current using a needle as an electrode that will be inserted into the concha of the ear. The subjects were lying in supinus.

    Other: percutaneous needle electrolysis

  • Other
    dry needling group

    Subjects were treated twice (one day and one week). The technique consisted in the puncture with a needle in the concha of the ear. The subjects were lying in supinus.

    Other: Dry needling

  • Sham comparator
    Sham group

    Subjects were treated twice (one day and one week). The technique consisted in the puncture with a sham-needle in the concha of the ear. The subjects were lying in supinus.

    Other: Sham needling

What researchers measure

Primary outcomes

  1. Skin temperature

    It´s a camera to take infrared thermal images. The images provide facial temperature measurement.

    Time frame: Change from Baseline up to 30 minutes

  2. Headache Impact Test (HIT-6)

    Headache Impact (HIT) is a tool used to measure the impact headaches have on your ability to function at work, home, school and in social situations. Your score shows you the effect that headaches they have in normal daily life and in their ability to function.A score of 60 or higher is associated with a very severe impact. A score equal to or less than 49 is associated with a low impact.

    Time frame: Change from Baseline up to 30 minutes

Secondary outcomes

  1. Skin bioimpedance

    It´s a system to acquire bio-electrical and physiological signals (galvanic skin conductance, heart rate variability), and transfer these signals to a computer for processing an analysis.

    Time frame: Change from Baseline up to 30 minutes

  2. Heart rate variability

    It´s a system to acquire bio-electrical and physiological signals (galvanic skin conductance, heart rate variability), and transfer these signals to a computer for processing an analysis.

    Time frame: Change from Baseline up to 30 minutes

  3. Numerical Rating Scale

    Patients vebally requested to rate their pain: "Rate your pain from = (no pain) to 10 (unbearable pain)

    Time frame: Change from Baseline up to three months

  4. Patients global impressions scale:

    It´s the Patient reported outcomes counterpart to the Clinical Global Impressions scale. The PGIS are 1-item questionnaire that ask an individual patient to rate the severity of a specific condition (single-state scales) at baseline and or to rate at endpoint the perceived change in is/her condition in response to therapy; in the other hand PGIC measures change in clinical status.

    Time frame: Change from Baseline up to three months

  5. Pittsburg Sleep Quality Index score

    Improvement in Pittsburg Sleep Quality Index (PSQI), Scale is 0 to 21, higher score is worse outcome

    Time frame: Change from Baseline up to three months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2022 (actual). Primary completion is estimated for Sep 2026, 54 months after the start.

Of 175 non-industry interventional studies with no phase under Headache, half reached primary completion within 14 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 37. This study's planned 54 months is above that.

Counting every sponsor, half of 193 studies reached it within 14 months; a quarter within 6 and three quarters within 38.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 1, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
