The pain experienced by burn patients during physical therapy range of motion exercises can be extreme and can discourage patients from complying with their physical therapy. We explored the novel use of immersive virtual reality (VR) to distract patients from pain during physical therapy.
This study was conducted at the burn care unit of a regional trauma center.
Twelve patients aged 19 to 47 years (average of 21% total body surface area burned) performed range of motion exercises of their injured extremity under an occupational therapist's direction.
Each patient spent 3 minutes of physical therapy with no distraction and 3 minutes of physical therapy in VR (condition order randomized and counter-balanced).
Five visual analogue scale pain scores for each treatment condition served as the dependent variables.
All patients reported less pain when distracted with VR, and the magnitude of pain reduction by VR was statistically significant (e.g., time spent thinking about pain during physical therapy dropped from 60 to 14 mm on a 100-mm scale). The results of this study may be examined in more detail at www.hitL.washington.edu/projects/burn/.
Results provided preliminary evidence that VR can function as a strong nonpharmacologic pain reduction technique for adult burn patients during physical therapy and potentially for other painful procedures or pain populations.
烧伤患者在物理治疗的关节活动度练习过程中所经历的疼痛可能极为剧烈，这会使患者不愿配合物理治疗。我们探索了沉浸式虚拟现实（VR）在物理治疗期间分散患者对疼痛注意力的新用途。
本研究在一家地区创伤中心的烧伤护理单元进行。
12名年龄在19至47岁之间（平均烧伤总面积为21%）的患者在职业治疗师的指导下对其受伤肢体进行关节活动度练习。
每位患者分别进行3分钟无干扰的物理治疗以及3分钟在VR环境下的物理治疗（治疗顺序随机且相互平衡）。
每种治疗条件治疗条件下的五个视觉模拟量表疼痛评分作为因变量。
所有患者报告称，在VR环境下分散注意力时疼痛减轻，且VR减轻疼痛的程度具有统计学意义（例如，在100毫米量表上，物理治疗期间用于思考疼痛的时间从60毫米降至14毫米）。本研究结果可在www.hitL.washington.edu/projects/burn/上进行更详细的查看。
研究结果提供了初步证据，表明VR可作为一种强大的非药物性减轻疼痛技术，用于成年烧伤患者的物理治疗期间，并且可能适用于其他疼痛治疗程序或疼痛人群。
