OBJECTIVES This study investigated (i) the impact of engaging with 20 minute simulated natural environments delivered via virtual reality (VR) on current mood state, and (ii) the impact of engaging with multiple VR sessions over a period of a week on the depressive symptoms of people with a SCI. DESIGN A randomized controlled trial design was utilised. SETTING Spinal Cord Injury Rehabilitation Unit in Australia PARTICIPANTS: Participants (n=24) were assigned to a group engaging in VR sessions during week 1 (Group 1, n=10), or week 2 (Group 2, n=14). INTERVENTIONS The intervention week involved participation in up to three 20-minute VR sessions over three consecutive days. The control condition involved regular rehabilitation practice over a week. MAIN OUTCOME MEASURES The Patient Health Questionnaire-8 (PHQ-8) was completed prior to the first week (T1), after the first week and prior to the second week (T2), and after the second week (T3). Current feeling states- depressed/happy, anxious/relaxed, and not feeling good/feeling good - were rated immediately prior and after each VR session. RESULTS Levels of happiness, relaxation, and feeling good, were significantly higher subsequent to engaging with each VR session. Between-group differences in PHQ-8 scores were significantly greater for participants who experienced the intervention during the first week compared to participants within the control group: intervention participants had significant improvements in psycho-emotional health. Within-group PHQ-8 scores reduced for each group subsequent to experiencing the intervention, however differences were not significant. CONCLUSIONS Engaging with simulated natural environments delivered via VR can favourably impact the psycho-emotional health of people with SCI receiving rehabilitation in hospital. Future research including larger samples and investigating the impact over a longer time period is required to confirm the findings presented.

参与通过虚拟现实提供的自然环境对在医院接受康复治疗的脊髓损伤患者的心理-情绪健康有什么影响？试点随机对照试验的结果

目标 本研究调查 (i) 参与通过虚拟现实 (VR) 提供的 20 分钟模拟自然环境对当前情绪状态的影响，以及 (ii) 在一周内参与多个 VR 会话对抑郁症的影响SCI 患者的症状。设计 采用随机对照试验设计。在澳大利亚设置脊髓损伤康复中心 参与者：参与者 (n=24) 被分配到第 1 周（第 1 组，n=10）或第 2 周（第 2 组，n=14）期间参与 VR 课程的组。干预 干预周包括连续三天参加最多三个 20 分钟的 VR 会议。控制条件包括一个多星期的定期康复练习。主要结局指标 患者健康问卷 8 (PHQ-8) 在第一周之前 (T1)、第一周之后和第二周之前 (T2) 以及第二周之后 (T3) 完成。当前的感觉状态——沮丧/快乐、焦虑/放松和感觉不好/感觉良好——在每次 VR 会话之前和之后立即进行评分。结果 参与每个 VR 会话后，快乐、放松和感觉良好的水平显着提高。与对照组的参与者相比，在第一周经历干预的参与者的 PHQ-8 分数的组间差异显着更大：干预参与者的心理情绪健康有显着改善。在经历干预后，每组的组内 PHQ-8 分数降低，然而差异并不显着。结论 参与通过 VR 提供的模拟自然环境可以对在医院接受康复治疗的 SCI 患者的心理情绪健康产生有利影响。未来的研究需要包括更大的样本并调查更长时间的影响，以确认所提出的发现。
