About this trial

The purpose of this study is to evaluate the use of various techniques in alleviating gag reflex following gag reflex stimulation.

Primary aim: To compare if there is any reduction in gag reflex from each of the following interventions

* Acupuncture (CV-24) * Tape * Anesthetic spray Secondary aim: to compare the degree of gag reduction

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

18 years or older (individuals below 18 years will be excluded from the study as the study procedures might not be well tolerated by them, and they are not the primary population on which these procedures are used).

Students, faculty, or staff of Tufts SDM

Subjects who score a 2 or higher on the Gagging Severity Index (GSI)7 and have a positive gag reflex response when stimulated with a cotton swab at the base of the tongue/uvula/tonsil region.

Disqualifiers

Adults unable to consent (cognitively impaired adults)

Wards of the state

Pregnant women (those that are self-reported)

Current use of anticoagulants

Trial design

Design model

Parallel

Treatments tested in this trial

  • Anesthetic spray

    Drug

    will be applied to back of the throat for 10 seconds; their chin will also be concealed from the GSI examiner using a small cup and masking tape.

  • Acupuncture

    Device

    A 6C file (endodontic instrumentation file) will be placed on the patient's mentolabial fold (CV24). This file will be concealed by a small paper cup; A clean alcohol wipe will be used to clean the mentolabial area prior to placing the "acupuncture needle" (6 C-File).

  • Masking Tape

    Genetic

    A piece of commercially available masking tape will be adhered to the patient's mentolabial fold and concealed by the small paper cup

Treatment groups

Trial outcomes

Primary outcomes

1

Change in Gag Reflex Severity Index (GSI) Score From Pre- to Post-Intervention

Change in Gag Reflex Severity Index (GSI) Score From Baseline to Post-Intervention * Acupuncture (CV-24) * Tape * Anesthetic spray Gag reflex severity will be assessed by clinicians using the Gagging Severity Index (GSI), based on definitions set by Dickinson and Fiske. GSI will first be recorded after initial gag stimulation with a cotton swab. Following randomization to one of three interventions (acupuncture, anesthetic spray, or masking tape), GSI will be recorded again. The change in GSI score will be used to measure change in gag response.

Time frame
90 minutes per subject

Secondary outcomes

1

Self-Reported Degree of Gag Reflex Reduction Using Visual Analog Scale (VAS)

Participants will complete an in-session survey to rate their gag reflex severity after the assigned intervention using a Visual Analog Scale (VAS). The VAS rating reflects the participant's perception of gag reduction following either acupuncture at CV24, anesthetic spray, or masking tape application.

Time frame
Immediately post-intervention during single study visit
