This study aimed to investigate the effect of virtual reality application on experimental ischemic pain created with a blood pressure instrument in healthy volunteers.
The research sample consisted of 172 volunteer adult students who conformed to the inclusion criteria. These individuals were assigned into an experimental (n=86) and a control group (n=86) by a simple randomization method. All individuals in the experimental and control groups wereexperimentally subjected to pain for two minutes by applying 260 mmHg of pressure 3-4 cm above the antecubital region of the left arm with an aneroid adult-type blood pressure instrument. During the procedure, the volunteers in the experimental group watched virtual reality images, while those in the control group received no intervention. Immediately after the procedure, the pain levels of the individuals in both groups were assessed with a Visual Analog Scale (VAS).
We found that the mean pain score of the individuals in the experimental group was 2.62±1.82, and that of individuals in the control group was 5.75±1.65. Results of the statistical analysis showed a statistically significant difference between the mean pain scores of the individuals in the experimental and control groups (p<0.001).
This study found that the use of virtual reality was effective in reducing the level of pain in healthy individuals. This method used a smartphone with widespread availability and ease of transportation, which can be used by health professionals as a non-pharmacological method in the management of pain.
本研究旨在探讨虚拟现实应用对健康志愿者使用血压仪产生的实验性缺血性疼痛的影响。
研究样本包括172名符合纳入标准的成年志愿者学生。通过简单随机化方法将这些个体分为实验组（n = 86）和对照组（n = 86）。实验组和对照组的所有个体均使用成人型无液血压仪在左臂肘前区域上方3 - 4厘米处施加260 mmHg的压力，实验性地使其疼痛两分钟。在此过程中，实验组的志愿者观看虚拟现实图像，而对照组的志愿者不接受任何干预。实验结束后，立即使用视觉模拟量表（VAS）评估两组个体的疼痛程度。
我们发现实验组个体的平均疼痛评分为2.62±1.82，对照组个体的平均疼痛评分为5.75±1.65。统计分析结果显示，实验组和对照组个体的平均疼痛评分之间存在统计学显著差异（p<0.001）。
本研究发现，使用虚拟现实可有效降低健康个体的疼痛程度。该方法使用的智能手机广泛可得且便于携带，可被卫生专业人员用作疼痛管理的非药物方法。
