Percutaneous Needle Electrolysis (PNE) on the Concha of the Ear

April 27, 2026 updated by: Prof. Dr. Daniel Pecos Martín, University of Alcala

Use of Infrared Thermography in the Measurement of Facial Blood Flow After the Application of Percutaneous Needle Electrolysis (PNE) on the Concha of the Ear

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.

  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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.
It´s an intervention of physiotherapy. It´s an invasive technique.
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.
It´s an intervention of physiotherapy. It´s an invasive technique.
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.
It´s an intervention of physiotherapy. It´s an invasive technique simulation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Skin temperature
Time Frame: Change from Baseline up to 30 minutes
It´s a camera to take infrared thermal images. The images provide facial temperature measurement.
Change from Baseline up to 30 minutes
Headache Impact Test (HIT-6)
Time Frame: Change from Baseline up to 30 minutes
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.
Change from Baseline up to 30 minutes

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Skin bioimpedance
Time Frame: Change from Baseline up to 30 minutes
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.
Change from Baseline up to 30 minutes
Heart rate variability
Time Frame: Change from Baseline up to 30 minutes
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.
Change from Baseline up to 30 minutes
Numerical Rating Scale
Time Frame: Change from Baseline up to three months
Patients vebally requested to rate their pain: "Rate your pain from = (no pain) to 10 (unbearable pain)
Change from Baseline up to three months
Patients global impressions scale:
Time Frame: Change from Baseline up to three months
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.
Change from Baseline up to three months
Pittsburg Sleep Quality Index score
Time Frame: Change from Baseline up to three months
Improvement in Pittsburg Sleep Quality Index (PSQI), Scale is 0 to 21, higher score is worse outcome
Change from Baseline up to three months
