背景技术背景：虚拟现实沉浸（VRI）是一种先进的计算机生成技术，减少了实验性和程序性医学治疗中疼痛的主观报告。此外，通过功能性磁共振成像测量，VRI显着降低了疼痛相关的大脑活动。相似性之间的解剖和神经内分泌途径的疼痛和瘙痒症可能证明VRI是一个合适的辅助基础和临床研究的复杂方面的瘙痒症。结论：比较效果的VRI与视听分心（AVD）技术的衰减瘙痒症患者的特应性皮炎和寻常型银屑病。24名患有慢性瘙痒症的患者（16名因特应性皮炎，8名因寻常型银屑病）被随机分配到使用特殊遮阳板或电脑屏幕玩互动电脑游戏。在暴露前、暴露期间和暴露后10分钟，使用0 - 10的视觉模拟量表对瘙痒强度进行自我评定。面试官在每个分心programmes.Results的三点量表上观察到的抓挠率：学生的t检验是显着的瘙痒强度减少之前和VRI和AVD（P=0.0002和P=0.01，分别），只有在VRI（P=0.017）之前和之后的评级之间显着。在这两个programmes.CONCLUSIONS：VRI和AVD技术表现出暂时减少瘙痒感觉的能力。进一步研究交互式计算机分心技术中断瘙痒发作的即时和晚期效应将为未来瘙痒症研究开辟潜在途径。
BACKGROUND: Virtual reality immersion (VRI), an advanced computer-generated technique, decreased subjective reports of pain in experimental and procedural medical therapies. Furthermore, VRI significantly reduced pain-related brain activity as measured by functional magnetic resonance imaging. Resemblance between anatomical and neuroendocrine pathways of pain and pruritus may prove VRI to be a suitable adjunct for basic and clinical studies of the complex aspects of pruritus.OBJECTIVES: To compare effects of VRI with audiovisual distraction (AVD) techniques for attenuation of pruritus in patients with atopic dermatitis and psoriasis vulgaris.METHODS: Twenty-four patients suffering from chronic pruritus - 16 due to atopic dermatitis and eight due to psoriasis vulgaris - were randomly assigned to play an interactive computer game using a special visor or a computer screen. Pruritus intensity was self-rated before, during and 10 min after exposure using a visual analogue scale ranging from 0 to 10. The interviewer rated observed scratching on a three-point scale during each distraction program.RESULTS: Student's t tests were significant for reduction of pruritus intensity before and during VRI and AVD (P=0.0002 and P=0.01, respectively) and were significant only between ratings before and after VRI (P=0.017). Scratching was mostly absent or mild during both programs.CONCLUSIONS: VRI and AVD techniques demonstrated the ability to diminish itching sensations temporarily. Further studies on the immediate and late effects of interactive computer distraction techniques to interrupt itching episodes will open potential paths for future pruritus research.
