Trillende anesthesie bij pijn na corticosteroïdinjecties

29 oktober 2026 bijgewerkt door: The University of Texas Medical Branch, Galveston

Het Effect van Trillingsanesthesie op Pijnperceptie van Patiënten bij Corticosteroïdinjecties in de Bovenste Extremiteit

This research study aims to evaluate injectional pain at the site of needle insertion for corticosteroid injections (CSI) of the upper extremity depending on different modes of anesthetics. Each individual's perception of pain upon receiving a CSI with two out of three modes of anesthesia (control/no anesthesia, vibrational anesthesia, vapo-coolant anesthesia) will be utilized to compare these variables and determine the method that is associated with the least pain.

Gedetailleerde beschrijving

As part of standard medical care, participants receive corticosteroid injections to the bilateral upper extremities. Following written informed consent, participants undergo the study procedures described below. Each participant receives a total of two injections, with one injection administered in each arm during a single study visit.

The type of anesthesia used for each injection is determined by random assignment using a computer-generated randomization sequence within the REDCap system. Participants are assigned to one of the following anesthesia combinations:

No anesthesia and vapocoolant spray topical anesthetic applied prior to injection No anesthesia and vibration anesthesia using the DigiVibe device throughout the duration of the injection Vapocoolant spray topical anesthetic applied prior to injection combined with vibration anesthesia using the DigiVibe device throughout the duration of the injection

For participants assigned to a DigiVibe group, the device is applied directly to the skin. The device contains a circular component that contacts the skin surface and provides vibratory stimulation. The injection is administered within the circular area while vibration is applied.

Upon completion of each injection, participants complete a numeric pain rating scale to assess perceived pain and comfort associated with the anesthesia method used.

Both corticosteroid injections are administered as part of routine clinical care. The use of topical anesthetic and/or vibratory anesthesia is performed solely for research purposes. The total duration of the study visit is approximately 20 minutes.

Beschrijving

Inclusion Criteria:

  • Any patient of the Principal Investigator who has clinically diagnosed bilateral arthritis, tendinopathy, arthropathy, or compression neuropathy of the hand, wrist, or elbow where treatment with corticosteroid injection is indicated.

  • Participants with inability to complete numeric pain rating scales
  • Participants with known allergies to triamcinolone acetonide, lidocaine, or bupivicaine
  • Participants without clinically diagnosed bilateral arthritis, tendinopathy, arthropathy, or compression neuropathy of the hand, wrist, or elbow.
  • Participants where treatment with corticosteroid injection is not indicated bilaterally.
  • Patients ≤ 18 years old

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Geen tussenkomst: Limb A: No Anesthesia and Limb B: Vapocoolant Spray Anesthesia

No anesthesia and vapocoolant spray topical anesthetic prior to injection. Participant will complete post-injection numeric pain rating scale assessing pain of injection.
Experimenteel: Limb A: No Anesthesia and Limb B:Vibration Anesthesia (DigiVibe)

Limb A: no anesthesia and Limb B:vibration anesthesia using the Digivibe device throughout the duration of the injection. Vibratory anesthesia will be administered throughout the duration of the injection. The circular part of the device will be applied directly to the surface of the skin. At the center of the circle is where the injection will be given, and the vibration will be turned on throughout the duration of the injection. After typical disposal of injection syringe, participant will complete post-injection numeric pain rating scale assessing pain of injection.
Apparaat: Digivibe Device

The Digivibe device uses pulsed vibrations to activate larger nerve fibers to interfere with pain signals. It has a circular shape to allow for injections in an area surrounded by pain-blocking vibrations.
Experimenteel: Limb A: Vapocoolant Spray Anesthesia Limb B: Vibration Anesthesia (DigiVibe)

Limb A: vapocoolant spray topical anesthetic prior to injection and Limb B: vibration anesthesia using the Digivibe device throughout the duration of the injection Vapocoolant spray anesthesia will be applied until the skin blanches, which is the standard clinical use. Corticosteroid injection will be given. After typical disposal of injection syringe, participant will complete post-injection numeric rating score.

Change in Pain Intensity From Baseline to Injection in the Arm
Tijdsspanne: Baseline (pre-injection) to time of injection

Change in participant-reported pain intensity will be calculated as the difference between baseline pain (prior to injection) and pain during injection using a 0-10 Numeric Rating Scale (NRS), where 0 indicates no pain and 10 indicates the worst possible pain. Scores will be compared across intervention groups (vibratory anesthesia, vapocoolant spray anesthesia, and no anesthesia).
