This study modified established clinical balance and walking measures and estimated the reliability, validity, and feasibility of using these measures to assess people post-stroke via videoconferencing.
Twenty-eight people with chronic stroke were recruited and completed the in-person balance and mobility tests. Five clinical measures were modified as virtual assessments over videoconferencing. Feasibility was evaluated by task completion rate, occurrence of adverse events, and technical difficulties. Test-retest reliability and agreement were examined by intra-class correlations and standard error of measurement between two testing days. Convergent validity was examined by the magnitude of associations between in-person and virtual assessments using Pearson or Spearman rank correlation.
Twenty-one participants (52% female) participated in both in-person and virtual assessments. No adverse events occurred. Technical challenges were experienced by eight participants. Test-retest reliability for timed up and go test, 30-seconds sit-to-stand, five-times sit-to-stand, functional reach test, and tandem stance resulted in intra-class coefficients of 0.97, 0.90, 0.77, 0.54, and 0.50 respectively. The standard error of measurement was low across all virtual assessments. The timed up and go test, five-times sit-to-stand, and 30-seconds sit-to-stand showed relationship with in-person assessments ( = -0.55 to -0.81).
Virtual assessment of walking and balance function in ambulatory people post-stroke is feasible; however, technical challenges were experienced. The test-retest reliability of virtual assessments of timed up and go test and sit-to-stand tasks for people with stroke, together with strong convergent validity of the measures compared to in-person assessments is promising.
本研究对既定的临床平衡和步行测量方法进行了修改，并评估了通过视频会议使用这些测量方法评估中风后患者的可靠性、有效性和可行性。
招募了28名慢性中风患者，他们完成了面对面的平衡和移动性测试。五项临床测量方法被修改为通过视频会议进行的虚拟评估。通过任务完成率、不良事件的发生情况和技术困难来评估可行性。通过组内相关性和两次测试日之间的测量标准误差来检验重测信度和一致性。使用Pearson或Spearman等级相关性通过面对面评估和虚拟评估之间的关联程度来检验收敛效度。
21名参与者（52%为女性）参加了面对面和虚拟评估。未发生不良事件。8名参与者遇到了技术挑战。计时起立行走测试、30秒坐立测试、五次坐立测试、功能性伸展测试和串联站立测试的重测信度导致组内系数分别为0.97、0.90、0.77、0.54和0.50。所有虚拟评估的测量标准误差都很低。计时起立行走测试、五次坐立测试和30秒坐立测试与面对面评估显示出相关性（=-0.55至-0.81）。
中风后非卧床患者步行和平衡功能的虚拟评估是可行的；然而，遇到了技术挑战。中风患者计时起立行走测试和坐立任务的虚拟评估的重测信度，以及与面对面评估相比这些测量方法的强收敛效度是有前景的。
