About this study

Official title: Determining the Variable Factors in Cutaneous Perception of Vibratory Stimulation

Perception of cutaneous sensory stimulation shows a large range of variability across multiple populations. Understanding this variability is critical to medical practice as interpretation of discomfort and pain is critical to diagnosis and treatment. Further, procedural medicine involves inflicting pain on patients in the form of injection of local anesthetic. Our protocol aims to determine how patients differentially interpret the non-noxious stimulation of vibration and the differences in perceiving anesthestic injection after the vibratory stimulus. We will explore how this ranges across all patients treated in a dermatological surgery out-patient setting. The goal is to identify which variables, such as age, gender, medical history, influence how sensation is interpreted.

What participants receive

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

  • Vibratory Anesthetic Device (VAD)Device

    This is a handheld ~10cm long tool, battery operated, which provides vibration at a rate of ~150 Hz

Study groups in NCT03467685
Study groupRoleWhat they receive
VAD Off armPlacebo comparatorThis will be the group that has the VAD placed on their skin in the off mode, i.e. no vibration
Receives: Device: Vibratory Anesthetic Device (VAD)
VAD On armExperimentalThis will be the group that has the VAD placed on their skin in the on mode, i.e. vibration
Receives: Device: Vibratory Anesthetic Device (VAD)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Numeric Rating Score

    This is a tool used to measure the degree of pain perceived by the patient with application of the tool on their skin and following the injection of anesthetic which is part of the routine medical care of the patient. Score ranges from 0 to 10 with higher score indicating more pain.

    Measured: Within 5 seconds of injection

Questions about this trial

What is this clinical trial studying?

A study testing Vibratory Anesthetic Device (VAD) in people with Pain, Acute and Anesthesia, Local, run by University of Pittsburgh 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 1 inclusion and 1 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 18 Sep 2020. 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 18 Sep 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Numeric Rating Score (time frame: Within 5 seconds of injection). 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 NCT03467685, which also lists 2 linked publications.

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 18 Sep 2020.
