Vibration Device Effect on Post-Injection Pain in the Upper Extremity

Not Applicable

Completed

• Conditions: Injection Site Inflammation; Upper Extremity Problem
• Interventions: Device: Electrical Vibration Device

• Registration Number: NCT05651139
• Lead Sponsor: Hatan Mortada

Brief Summary

Background: Vibratory stimulation is one of several non-pharmacological techniques used to reduce pain. Local vibration therapy generates vibrations that can penetrate up to 6 centimeters into the tissue and is utilized to manage muscle tone, alleviate localized pain, and induce an increase in blood and lymphatic circulation. This therapy is most commonly used to treat chronic pathologies of the muscles, tendons, and joints. A few studies investigating the effects of local vibration therapy on skeletal muscles and joints have found it to be beneficial in improving joint mobility and decreasing pain. Previous reports have indicated that whole-body vibration can suppress chronic low back pain, knee osteoarthritis, and peripheral neuropathy. The aim of this study is to evaluate the effects of the application of vibration stimulation on upper extremity injection-induced pain and satisfaction.

Objectives: The purpose of this study is to assess the effect of vibration stimulation application on upper extremity injection pain and satisfaction.

Methods: An electrical massage kit that induces vibration will be used on adult patients who are scheduled to receive local anesthesia or corticosteroid injections in their upper extremities. Two validated scales will be used to first assess the pain after the injection and the patient's satisfaction following the use of the vibration device.

Detailed Description

Study design:

randomized controlled trial

Study duration:

12 months, beginning in November 2022 and ending in May 2023.

Study settings:

Data will be collected from patients coming to the plastic surgery department.

Study population: adult patients scheduled to receive local anesthesia or corticosteroid injections in their upper extremities.

Eligibility criteria: Adult patients with (ASA) physical status class 1 who are scheduled to receive local anesthesia or corticosteroid injections

Sample size:

60 adult patients who are attending plastic surgery clinic for upper extremity injections.

Ethical consideration:

The authors have no ethical or financial considerations to disclose.

Rationale for using the device:

Vibrational stimulation is a relevant treatment option for pain. It has shown promise in reducing pain in a number of musculoskeletal conditions where it has been used successfully. There aren't any randomized controlled trials that explore the effect vibration stimulation has on post-injection pain in the upper extremity.

Data collection method:

Data will be collected through a data sheet. The co-investigators will collect the data directly from the patients after the injections and measure the pain using a visual analogue scale for pain. A satisfaction visual scale is also provided to assess satisfaction with the vibration device. There will also be a control group that will receive the injections without using the vibration device. Randomization will be carried out using a coin flip.

Statistical analysis:

Data will be analyzed using SPSS 24.0 version statistical software. Descriptive statistics (mean, standard deviation, frequencies, and percentages) will be used to describe the quantitative and categorical variables. Bivariate statistical analysis will be carried out using appropriate (chi-square, student's t test, one-way analysis of variance, and Pearson's correlation) statistical test, based on the type of study and outcome variables. A p-value of \<0.05 and 95% CI will be used to report the statistical significance and precision of results

Arm && Interventions

Group	Intervention	Description
Receiving vibration stimulation post-injection	Electrical Vibration Device	Using a vibration device post-injection on the affected area.

Primary Outcome Measures

Name	Time	Method
The effects of vibration on upper extremity injection-induced pain	Pain will be measured immediately after receiving the intervention (with in 2 minutes)	Measuring the pain using the Visual Analog Scale (VAS) for pain, which is a validated tool.; the scale measures pain from 0 (no pain) to 10 (pain as bad as it could possibly be)
The effects of vibration on injection satisfaction for upper extremity injections	The satisfaction will be measured immediately post-injection and intervention (with in 5 minutes)	The satisfaction will be measured using Satisfaction visual analog scale, which is a validated tool.; the scale measures the satisfaction from 0 (not satisfied) to 10 (very satisfied)
