The Effects of Vibration and Pressure Interventions

Study Overview
=================
Brief Summary
-----------------
This study aimed to evaluate two methods (pressure and vibration intervention) used to reduce pain during IM injections in children.

Detailed Description
-----------------
Objectives: This study was conducted to evaluate the effects of the Vibration and Pressure Intervention for reducing pain during intramuscular (IM) injections in children. Design: The study was conducted via a randomized controlled design. Setting: The study population consisted of children in the five to 10 age group admitted to the emergency department of a public hospital (Samsun Education and Research Hospital) between August 2022 and October 2022 and who received an IM injection as part of the medical treatment in child emergency department. Interventions: The study data were collected from the children, who were divided into Vibration Intervention group, Pressure Intervention group, and control groups. Main outcome measures: The children's pre-procedure fear and anxiety levels were evaluated using the Children's Fear Scale (CFS), and Children' Anxiety Meter State. Then, their pain levels during the procedure were evaluated using the Wong-Baker FACES Rating Scale.

Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: The Vibration Intervention Group (VI)<br>After the injection area was determined in the VI group, the vibration device was held for 30 seconds in the area to be injected, then the injection was applied by pulling up 3 cm while the device was operating. | Behavioral: The Vibration Intervention<br>* The vibration frequency of the massager, which accelerates blood circulation, is 6000 / min, it works with a 1.5 volt battery. Can be used easily with one hand. The vibration simulator design is based on the gate-control theory, which allows for a reduction in the perceived amount of pain experienced during injection by closing the pain gate in the spinal cord in creating a stimulus on the skin.<br>|
| Experimental: The Pressure Intervention Group<br>After the injection area was determined in the PI group, 30 seconds light pressure was applied with the thumb and then the injection was given | Behavioral: The Pressure Intervention<br>* Pressure was placed in the ıntramuscular area properly 30 seconds before injection. Then the injection process was completed.<br>|
| No Intervention: The Control Group<br>The routine IM injection was applied to the children in the control group. | |

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Children's Fear Scale (CFS) | The Children's Fear Scale (CFS) is a scale used to assess the level of anxiety in children. The scale is a visual measurement tool with scores ranging from 0-4 points. It consists of five facial expressions, ranging from a neutral to a frightened expression, and is suitable for use with children aged 5-10 years (Inan & Inal, 2019; McMurtry, Noel, Chambers, & McGrath, 2011; Özalp Gerçeker, Ayar, Özdemir, & Bektaş, 2018). The evaluation of the Turkish psychometric properties of the scale, which was developed by McMurty et al. for paediatric patients, was conducted by Özalp Gerçeker et al. (2018), and the scale was translated into the Turkish language (Özalp Gerçeker et al., 2018). The CFS has demonstrated good evidence of test-retest (r = 0.76, p < 0.001), and inter-rater (0.51, P < 0.001) reliability, as well as construct validity, (rs ¼ when used with children (McMurtry vd., 2011 | during procedure | 
| The Children's Anxiety Meter-State (CAM-S) | The Children's Anxiety Meter-State (CAM-S) assesses children's anxiety at medical procedures. It is drawn like a thermometer with a bulb at the bottom. It includes horizontal lines going up to the top (0-10). Children are asked to mark their feelings right now to measure state anxiety (Kleiber & Mccarthy, 2006). CAM-S was validated in children aged 4-10 years during an intravenous procedure. It is significantly associated with all parent measures and observed distress ratings (Ersig et al., 2013). Gerçeker et al. (2018) conducted the psychometric properties of CAM-S in the Turkish population. They revealed a significant negative correlation between the CAM-S scores and children's ages (β = 0.340, p < .001). | during procedure | 
| Wong-Baker FACES Rating Scale | It is a horizontal scale developed by Wong and Baker in 1983 for children over 3 years of age who can express themselves. In this scale, pain scores are given to faces according to numerical values. The lowest score is 0 and the highest score is 10. As the score obtained from the scale increases, the severity of pain increases. During the application of the scale, it is stated to the child that each of the facial expressions belongs to a person. It is stated that the child who has no pain expresses a happy face, while the child who has a little or a lot of pain during the procedure has sad faces. | during procedure |
