Trial summary

The aim of this proposal is to investigate brain response and connectivity changes evoked by video-guided acupuncture imagery treatment (VGAIT) and verum and sham acupuncture in healthy and patient populations to elucidate the underlying brain mechanisms of mind-body interaction, imagery, and acupuncture.

What participants receive

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

  • Real acupunctureOther

    Verum acupuncture will be applied on the right SP6 and SP9. For each subject, leg position, acupoint location, and needling parameters (1-2 cm depth, 120 rotations / minute, 90˚ insertion angle, moderate deqi sensations on a 0-10 scale) will be kept constant. For the low dose acupuncture group, needles will be rotated at one point and then the other in 15-second rotations with 20-30 second breaks. The specific starting acupoint will be randomized across subjects but kept consistent for each subject across sessions.

  • Sham acupunctureOther

    Placebo acupuncture will be applied at two sham points using specially designed sham acupuncture needles [20, 35, 104-106]. The sham needles differ from regular needles by possessing blunt and retractable tips. Instead of penetrating the skin, the point of the Streitberger needle retracts up the handle shaft when the acupuncturist presses it against the skin. This sham device has been validated by studies showing that subjects cannot distinguish between genuine and sham needling [20, 35, 104]. Two sham points will be used during placebo acupuncture: sham point 1 is located 1 cun posterior to the superior 1/3 of K9 and K10. Sham 2 is located 1 cun posterior to K8. Both points are located on the leg where there is no meridian passing through. Sham acupuncture treatment will be the same as verum acupuncture.

  • VGAITOther

    In Session 1, all patients will first be introduced to acupuncture treatment, particularly the sensation evoked by acupuncture needles. This will be followed by a five-minute acupuncture exposure applied by a licensed acupuncturist. The exposure will include multiple acupuncture needle manipulations across the two acupoints (SP 6 and SP 9) used in this study. The paradigm applied will be identical to real acupuncture treatment, and the procedure will also be video recorded for the following session. At the beginning of the VGAIT session, patients will be trained for imagery acupuncture outside the fMRI scan. Subjects will first read a script introducing the imagery acupuncture treatment. Then, VGAIT will be applied during scanning. Identical to the acupuncture treatment, there are two fMRI scans during VGAIT, each lasting about 10 minutes. We will ask the patient to measure the sensations they feel during treatment using the MGH Acupuncture Sensation Scale (MASS) after treatment.

  • VGAIT controlOther

    The control condition will be the same as VGAIT, except we will use cotton swabs repeatedly touching at non-acupoints with a frequency of about 1 Hz using the same paradigm of verum / sham acupuncture. They will also read a script describing what they are about to see. Then, VGAIT control will be applied during scanning. We will ask the patient to measure the sensations they feel during treatment using the MASS after treatment.

Study groupRoleWhat they receive
Healthy VolunteersExperimentalIn this experiment, we will apply a crossover design in healthy subjects. Each subject will receive four treatments in four separate sessions: 1) VGAIT, 2) VGAIT control condition, 3) real acupuncture, and 4) sham acupuncture. Each session will be separated by at least 7 days. Subjects will participate in five experimental sessions: a training and familiarity behavioral session and four fMRI sessions during which the subject will receive one of the four treatments.

Questions about this trial

What is this clinical trial studying?

A study testing Real acupuncture and VGAIT in people with Pain, run by Massachusetts General Hospital at 1 site in United States.

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 2 inclusion and 4 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 21 Jul 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 United States. 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?

fMRI signal increases (time frame: 4 days; Sessions 2-5). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 21 Jul 2026; AzTrials last refreshed its copy on 8 Nov 2026.
