OBJECTIVE: We conducted a randomized controlled study to determine the effects of virtual reality (VR) distraction on pain and range of motion (ROM) in patients hospitalized for burn care during active physical therapy exercises. METHOD: Thirty-nine participants aged 15 to 66 (M = 36) years with significant burn injuries (mean burn size = 14% TBSA) participated. Under therapist supervision, using a within-subjects design, participants performed unassisted active ROM exercises both with and without VR distraction in a randomized order. Therapists provided participants with instructions but did not physically assist with stretches. Maximum active ROM was measured using a goniometer. A 0-100 Graphic Rating Scale (GRS) was used to assess the cognitive, affective, and sensory components of pain. A GRS rating of the amount of "fun" during stretching served as a measure of positive experience. RESULTS: Participants reported lower mean GRS ratings during VR, relative to No VR, for worst pain, pain unpleasantness, and time spent thinking about pain. They also reported having a more positive experience during VR than during No VR. However, patients did not show greater ROM during VR. CONCLUSION: Immersive VR reduced pain during ROM exercises that were under the control of the patient. (PsycINFO Database Record (c) 2018 APA, all rights reserved).
目的:我们进行了一项随机对照研究,以确定虚拟现实(VR)分散注意力对接受烧伤治疗住院患者在主动物理治疗运动期间疼痛和活动范围(ROM)的影响。
方法:39 名年龄在 15 至 66 岁(M=36)岁、有明显烧伤损伤的参与者(平均烧伤面积=14%TBSA)参加了研究。在治疗师的监督下,参与者采用自身对照设计,以随机顺序在有和没有 VR 分散注意力的情况下进行无辅助主动 ROM 运动。治疗师为参与者提供指导,但不协助伸展运动。使用量角器测量最大主动 ROM。0-100 图形评定量表(GRS)用于评估疼痛的认知、情感和感觉成分。伸展过程中“乐趣”的 GRS 评分作为积极体验的衡量标准。
结果:与无 VR 相比,参与者在 VR 时报告的最差疼痛、疼痛不愉快和思考疼痛时间的平均 GRS 评分更低。他们还报告说在 VR 期间比在无 VR 期间有更积极的体验。然而,患者在 VR 期间并没有表现出更大的 ROM。
结论:沉浸式 VR 减轻了患者控制下的 ROM 运动中的疼痛。(PsycINFO 数据库记录(c)2018 APA,保留所有权利)。
