The objective of the present study was to compare the feasibility, safety, and satisfaction of an immersive virtual reality system developed specifically for cognitive-sensory-motor training among older adult fallers and nonfallers and adult individuals. This was a cross-sectional observational study, and 20 adults, 20 nonfaller older adults, and 20 faller older adults were assessed. The primary outcome was feasibility assessed with safety and satisfaction measures. Safety outcomes were associated with adverse events occurred during the experience with the immersive virtual reality system (IVRS), assessed through the Simulator Sickness Questionnaire and by registering the falls, pain, or any discomfort reported by the participants. Satisfaction was assessed with a structured questionnaire, answered after 10 minutes of experiencing the IVRS. The dates were assessed with one-way analysis of variance or the Kruskal-Wallis test and Bonferroni post hoc test. The results showed that the IVRS was safe and the participants related good satisfaction with the system. Most of participants related no symptoms (93.6 percent) or light cybersickness symptoms (6.0 percent). There were no occurrences of falls or pain associated with the IVRS. The IVRS was feasible for adults and nonfaller and faller older adults.

具有运动和认知组件的沉浸式虚拟任务：成人和老年人跌倒者和非跌倒者的可行性研究。

本研究的目的是比较专为老年跌倒者和未跌倒者以及成人个体进行认知-感觉-运动训练而开发的沉浸式虚拟现实系统的可行性、安全性和满意度。这是一项横断面观察性研究，对 20 名成年人、20 名未跌倒的老年人和 20 名跌倒的老年人进行了评估。主要结果是通过安全性和满意度措施评估的可行性。安全结果与沉浸式虚拟现实系统 (IVRS) 体验期间发生的不良事件相关，通过模拟器疾病问卷和记录参与者报告的跌倒、疼痛或任何不适进行评估。使用结构化问卷评估满意度，在体验 IVRS 10 分钟后回答。使用单向方差分析或 Kruskal-Wallis 检验和 Bonferroni 事后检验评估日期。结果表明，IVRS 是安全的，参与者对该系统的满意度很高。大多数参与者没有任何症状 (93.6%) 或轻微的晕机症状 (6.0%)。没有发生与 IVRS 相关的跌倒或疼痛。IVRS 对成年人和不会跌倒和跌倒的老年人是可行的。
