Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Pain, Acute Anesthesia, Local Dermatology/Skin - Other Device: Vibratory Anesthetic Device (VAD) Not Applicable

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Intervention Model Description:

Subjects will be randomly assigned into one of two groups:

Group 1: Vibratory anesthetic device (VAD) is in the OFF mode Group 2: VAD is in the ON mode

We will use a random number generator to place patients into one of the two groups.

Masking: Single (Participant)
Masking Description: Subjects will be asked to close their eyes prior to the vibration anesthetic device (VAD) being applied to their skin. Only the user will know whether the VAD will be on or off based on the result of a random number generator. This will prevent anticipatory changes on the subjects side. The subject will be aware of the intervention after the device is turned on or left in the off position.
Primary Purpose: Prevention
Official Title: Determining the Variable Factors in Cutaneous Perception of Vibratory Stimulation
Actual Study Start Date : June 19, 2018
Estimated Primary Completion Date : March 2019
Estimated Study Completion Date : March 2019

Arm Intervention/treatment
Placebo Comparator: VAD Off arm
This will be the group that has the VAD placed on their skin in the off mode, i.e. no vibration
Device: Vibratory Anesthetic Device (VAD)
This is a handheld ~10cm long tool, battery operated, which provides vibration at a rate of ~150 Hz

Experimental: VAD On arm
This will be the group that has the VAD placed on their skin in the on mode, i.e. vibration
Device: Vibratory Anesthetic Device (VAD)
This is a handheld ~10cm long tool, battery operated, which provides vibration at a rate of ~150 Hz




Primary Outcome Measures :
  1. Numeric Rating Score [ Time Frame: Within 5 seconds of injection ]
    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.
