Upper-limb virtual rehabilitation (VR) in adult acquired brain injury (ABI) is based largely on systems administered on a one-to-one basis. Multi-user interaction between co-located participants may offer advantages over single-user methods. The present study examined the feasibility of deploying a co-located VR system (Resonance) in a clinical setting. Following a baselining period, 5 patients with ABI completed 12 Resonance sessions over 4–6 weeks. Feasibility criteria included recruitment, intervention delivery, attrition, user experience, and suitability of outcome measures. Individual participant motor proficiency (box and blocks task) was examined using a time-series analysis with reliable change indices and curve fitting. All feasibility criteria were satisfied, with positive reports of user experience. Repeated collection of outcome measures was successfully integrated into the training schedule. Time-series analysis was successfully conducted, providing a detailed account of individual training-related change. Within a clinical setting, it was feasible to deliver Resonance and regularly monitor motor function. User feedback regarding the co-located VR intervention was generally positive, but expectations regarding the level of immersion may need to be managed. Individual time-series analysis is recommended as an adjunct to group-based analysis in future VR research. These findings can inform the design of a clinical trial.

成人后天性脑损伤（ABI）的上肢虚拟康复（VR）主要基于一对一管理的系统。同位参与者之间的多用户交互可能比单用户方法更具优势。本研究检查了在临床环境中部署共置虚拟现实系统（Resonance）的可行性。在基线期之后，5名ABI患者完成了12次共振历时4-6周。可行性标准包括招聘，干预措施交付，人员流失，用户体验以及结果指标的适用性。使用具有可靠的变化指数和曲线拟合的时间序列分析，检查了各个参与者的运动能力（框框任务）。满足了所有可行性标准，并获得了积极的用户体验报告。重复收集结果指标已成功纳入培训计划。成功进行了时间序列分析，提供了与培训相关的个人变更的详细说明。在临床环境中，实现共振是可行的并定期监视电动机功能。用户对共处一地的VR干预的反馈总体上是积极的，但可能需要管理对沉浸程度的期望。建议在未来的VR研究中将个人时间序列分析作为基于组的分析的补充。这些发现可以为临床试验的设计提供依据。
