BACKGROUND Virtual reality (VR)-based rehabilitation is considered a beneficial therapeutic option for stroke rehabilitation. This pilot study assessed the clinical feasibility of a newly developed VR-based planar motion exercise apparatus (Rapael Smart Board™ [SB]; Neofect Inc., Yong-in, Korea) for the upper extremities as an intervention and assessment tool. METHODS This single-blinded, randomized, controlled trial included 26 stroke survivors. Patients were randomized to the intervention group (SB group) or control (CON) group. During one session, patients in the SB group completed 30 min of intervention using the SB and an additional 30 min of standard occupational therapy; however, those in the CON group completed the same amount of conventional occupational therapy. The primary outcome was the change in the Fugl-Meyer assessment (FMA) score, and the secondary outcomes were changes in the Wolf motor function test (WMFT) score, active range of motion (AROM) of the proximal upper extremities, modified Barthel index (MBI), and Stroke Impact Scale (SIS) score. A within-group analysis was performed using the Wilcoxon signed-rank test, and a between-group analysis was performed using a repeated measures analysis of covariance. Additionally, correlations between SB assessment data and clinical scale scores were analyzed by repeated measures correlation. Assessments were performed three times (baseline, immediately after intervention, and 1 month after intervention). RESULTS All functional outcome measures (FMA, WMFT, and MBI) showed significant improvements (p < 0.05) in the SB and CON groups. AROM showed greater improvements in the SB group, especially regarding shoulder abduction and internal rotation. There was a significant effect of time × group interactions for the SIS overall score (p = 0.038). Some parameters of the SB assessment, such as the explored area ratio, mean reaching distance, and smoothness, were significantly associated with clinical upper limb functional measurements with moderate correlation coefficients. CONCLUSIONS The SB was available for improving upper limb function and health-related quality of life and useful for assessing upper limb ability in stroke survivors. TRIAL REGISTRATION The study was registered with the clinical research information service (CRIS) ( KCT0003783 , registered 15 April 2019; retrospectively registered).

基于虚拟现实的平面运动锻炼对上肢功能，运动范围和健康相关的生活质量的影响：一项多中心，单盲，随机，对照的试验研究。

背景技术基于虚拟现实（VR）的康复被认为是中风康复的有益治疗选择。这项先导研究评估了一种新开发的基于VR的平面运动锻炼仪（Rapael Smart Board™[SB]；韩国Yong-in的Neofect Inc.）作为干预和评估工具的临床可行性。方法这项单盲，随机，对照试验包括26名卒中幸存者。将患者随机分为干预组（SB组）或对照组（CON）组。在一个疗程中，SB组患者使用SB完成了30分钟的干预，并完成了30分钟的标准职业治疗。但是，CON组的患者完成了相同数量的常规职业治疗。主要结果是Fugl-Meyer评估（FMA）得分的变化，次要结果是沃尔夫运动功能测验（WMFT）得分，近端上肢活动范围（AROM），改良的Barthel指数（MBI）和中风影响量表（SIS）得分的变化。使用Wilcoxon符号秩检验进行组内分析，并使用协方差的重复测量分析进行组间分析。另外，通过重复测量相关性分析了SB评估数据与临床量表评分之间的相关性。评估进行了3次（基线，干预后立即和干预后1个月）。结果所有功能结局指标（FMA，WMFT和MBI）在SB和CON组均显示出显着改善（p <0.05）。AROM在SB组中显示出更大的进步，特别是在肩关节外展和内旋方面。时间×小组互动对SIS总分有显着影响（p = 0.038）。SB评估的一些参数，例如探查面积比，平均到达距离和光滑度，与具有适度相关系数的临床上肢功能测量显着相关。结论SB可用于改善上肢功能和与健康相关的生活质量，并可用于评估中风幸存者的上肢能力。试验注册本研究已在临床研究信息服务（CRIS）中注册（KCT0003783，2019年4月15日注册；回顾注册）。SB评估的某些参数，例如探查面积比，平均到达距离和光滑度，与具有适度相关系数的临床上肢功能测量显着相关。结论SB可用于改善上肢功能和与健康相关的生活质量，并可用于评估中风幸存者的上肢能力。试验注册本研究已在临床研究信息服务（CRIS）中注册（KCT0003783，2019年4月15日注册；回顾注册）。SB评估的某些参数，例如探查面积比，平均到达距离和光滑度，与具有适度相关系数的临床上肢功能测量显着相关。结论SB可用于改善上肢功能和与健康相关的生活质量，并可用于评估中风幸存者的上肢能力。试验注册本研究已在临床研究信息服务（CRIS）中注册（KCT0003783，2019年4月15日注册；回顾注册）。结论SB可用于改善上肢功能和与健康相关的生活质量，并可用于评估中风幸存者的上肢能力。试验注册本研究已在临床研究信息服务（CRIS）中注册（KCT0003783，2019年4月15日注册；回顾注册）。结论SB可用于改善上肢功能和与健康相关的生活质量，并可用于评估中风幸存者的上肢能力。试验注册本研究已在临床研究信息服务（CRIS）中注册（KCT0003783，2019年4月15日注册；回顾注册）。
