背景和目的：开发虚拟现实（VR）增强骑行套件（VRACK）是为了解决慢性中风患者的运动控制和健身缺陷问题。在本文中，我们报告了使用 VR 增强骑行套件改善中风后慢性期个体的心肺 (CR) 健康状况的安全性、可行性和有效性。方法：四名慢性中风患者（47-65 岁且中风后≥3 年），有残余下肢损伤 (Fugl-Meyer 24-26/34)，社区步行能力有限（步态速度范围） 0.56-1.1 m/s）参与了这项研究。安全性定义为不存在不良事件。可行性是通过出勤率、总锻炼时间以及通过存在问卷（PQ）测量的“参与度”来衡量的。在为期 8 周的训练计划之前和之后，使用次最大自行车测力计测试来评估 CR 健身的效果。 结果：干预措施安全可行，参与者发生 1 次不良事件，遵守率 100%，每周骑行 90 至 125 分钟，平均 PQ 得分为 39 (SD 3.3)。峰值摄氧量有统计学上显着的改善（13%；P = 0.035），范围为 6% 至 24.5%。 讨论和结论：对于这些人来说，中风后，VR 增强自行车，使用他们的心率来设置他们的化身速度，促进足够持续时间和强度的训练，以促进 CR 健身。此外，耐力训练也从自行车转移到了步行。 VR 增强骑行可能是治疗师工具的补充，用于同时进行中风后个人的活动能力训练和健康促进。提供视频摘要（请参阅视频，补充数字内容 1，http://links.lww.com/JNPT/A53），了解作者的更多见解。
Background and Purpose: Avirtual reality (VR) augmented cycling kit (VRACK) was developed to address motor control and fitness deficits of individuals with chronic stroke. In this article, we report on the safety, feasibility, and efficacy of using the VR augmented cycling kit to improve cardiorespiratory (CR) fitness of individuals in the chronic phase poststroke.Methods: Four individuals with chronic stroke (47-65 years old and >= 3 years poststroke), with residual lower extremity impairments (Fugl-Meyer 24-26/34), who were limited community ambulators (gait speed range 0.56-1.1 m/s) participated in this study. Safety was defined as the absence of adverse events. Feasibility was measured using attendance, total exercise time, and "involvement" measured with the presence questionnaire (PQ). Efficacy of CR fitness was evaluated using a submaximal bicycle ergometer test before and after an 8-week training program.Results: The intervention was safe and feasible with participants having 1 adverse event, 100% adherence, achieving between 90 and 125 minutes of cycling each week, and a mean PQ score of 39 (SD 3.3). There was a statistically significant (13%; P = 0.035) improvement in peak VO2, with a range of 6% to 24.5%.Discussion and Conclusion: For these individuals, poststroke, VR augmented cycling, using their heart rate to set their avatar's speed, fostered training of sufficient duration and intensity to promote CR fitness. In addition, there was a transfer of training from the bicycle to walking endurance. VR augmented cycling may be an addition to the therapist's tools for concurrent training of mobility and health promotion of individuals poststroke.
