About this study
Official title: Investigate the Change in Facial Pain Threshold During Auricular Acupuncture in Healthy Volunteers: A Pilot Study
Background: The effects and biological mechanisms of auricular acupuncture on the human body have been increasingly observed in clinical and experimental studies, particularly the analgesic effects. Auricular acupuncture in the Shenmen, Nervous Subcortex, Jaw and Tooth groups has been shown in the Acupuncture 2 textbook of the Faculty of Traditional Medicine - University of Medicine and Pharmacy, Ho Chi Minh City and clinical studies to be effective in reducing facial pain.
This study aims to examine: (1) the change in facial pain threshold when performing auricular acupuncture in the acupoints of Shenmen (TF4), Nervous Subcortex (AT4), Jaw (LO3) and Tooth (LO1) on the left ear, (2) the change in facial pain threshold when performing auricular acupuncture in the acupoints of Shenmen, Nervous Subcortex, Jaw and Tooth on the right ear and (3) examining the unfavorable effects of the procedure.
Read the detailed description
The effects and biological mechanisms of auricular acupuncture on the human body have been increasingly observed in clinical and experimental studies, particularly the analgesic effects. When the downward neurotransmitter pathway is activated, endogenous opioids (beta endorphins) are released, which inhibit pain perception. Furthermore, according to the gate control theory (spinal segmentation mechanism), auricular acupuncture aids in the activation of pain-suppressive stimuli by myelinated afferent fibers (Aβ), as opposed to stimuli with damage from poorly myelinated (Aδ) or unmyelinated (C) fibers. Besides, according to human physiology, the trigeminal nerve is involved in sensory control of the face, has a branching distribution to the skin of the pinna, and has afferent conduction of mechanical stimuli acting on it. Auricular acupuncture in the Shenmen, Nervous Subcortex, Jaw and Tooth groups has been shown in the Acupuncture 2 textbook of the Faculty of Traditional Medicine - University of Medicine and Pharmacy, Ho Chi Minh City and clinical studies to be effective in reducing facial pain.
This was the first study in Vietnam to investigate the effect of auricular acupuncture on the change in facial pain threshold during auricular acupuncture on acupoints such as Shenmen, Nervous Subcortex, Jaw and Tooth. The findings of the study can be used to supplement scientific evidence regarding the effects of auricular acupuncture in the treatment of clinical facial pain.
The investigators performed a randomized, controlled crossover experiments. A crossover study has two advantages over both a parallel study and a non-crossover longitudinal study. First, the influence of confounding covariates is reduced because each crossover patient serves as their own control. In a randomized non-crossover study it is often the case that different treatment-groups are found to be unbalanced on some covariates. In a controlled, randomized crossover designs, such imbalances are implausible (unless covariates were to change systematically during the study). Second, optimal crossover designs are statistically efficient, and so require fewer subjects than do non-crossover designs (even other repeated measures designs). In our study, the subjects are randomly assigned to two arms of the study which receive different treatments. A crossover trial has a repeated measures design in which each patient is assigned to a sequence of two treatments, one of which is auricular acupuncture, and a placebo test is performed on that volunteer a week later. Wilcoxon sign-rank test, paired T test and Pearson's chi-squared test were used for comparison of means.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AURICULAR ACUPUNCTUREProcedure or surgery
Auricular acupuncture is a method for diagnosing and treating physical and psychosomatic dysfunctions by stimulating a specific point in the ear. To conducting this intervention, the investigators use press tack needles to perform auricular acupuncture.
PLACEBOOther
For this intervention, instead of needles, the investigators use four pieces of tape.
| Study group | Role | What they receive |
|---|---|---|
| First auricular acupuncture, then sham acupuncture in left ear | Experimental | Participants are experienced two phases of our study. The first phase, participants are received auricular acupuncture at TF4, AT4, LO1, LO3 points in the left ear. The second phase, participants are received sham acupuncture at the same points. The facial pain threshold will be recorded before and after performing auricular acupuncture. Receives: Procedure: AURICULAR ACUPUNCTURE; Other: PLACEBO |
| First auricular acupuncture, then sham acupuncture in right ear | Experimental | Participants are experienced two phases of our study. The first phase, participants are received auricular acupuncture at TF4, AT4, LO1, LO3 points in the right ear. The second phase, participants are received sham acupuncture at the same points.

Questions about this trial
What is this clinical trial studying?
A study testing AURICULAR ACUPUNCTURE in people with Healthy Volunteers, run by Bui Pham Minh Man at 1 site in Vietnam.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 3 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 6 Dec 2022. 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 Vietnam. 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?
Evaluate the change of facial pain threshold when using auricular acupuncture and using sham acupuncture in the left ear in healthy volunteers by the multi-capacity digital force gage FDIX of Wagner Inc (Newton Unit of Measurement) (time frame: During procedure). 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 NCT05213299, which also lists 1 linked publication.
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 6 Dec 2022.
