适合上下文的传感器技术的发展可以减轻撒哈拉以南非洲康复临床医生和医疗保健设施中中风的重大负担。但是，许多商业可穿戴的传感器超出了大多数非洲人的财务能力。在这项研究中，我们使用8个相机的维科（Vicon）运动捕获系统作为参考标准，评估了低成本可穿戴传感器（即外展传感器）的同时有效性，以测量31位健康人员的上肢运动运动学。与参考系统相关联（r范围：0.808-0.990）和一致性（平均差异范围：-1.60至1.10）与参考系统无关，无论任务或运动学参数如何。此外，Bland-Altman分析表明，没有明显的系统错误。这项研究表明，可以使用外展传感器准确测量上肢运动运动学，并有可能增强撒哈拉以南非洲的中风评估和康复。
The development of context-appropriate sensor technologies could alleviate the significant burden of stroke in Sub-Saharan African rehabilitation clinicians and health care facilities. However, many commercially available wearable sensors are beyond the financial capabilities of the majority of African persons. In this study, we evaluated the concurrent validity of a low-cost wearable sensor (i.e., the outREACH sensor) to measure upper limb movement kinematics of 31 healthy persons, using an 8-camera Vicon motion capture system as the reference standard. The outREACH sensor showed high correlation (r range: 0.808-0.990) and agreement (mean difference range: -1.60 to 1.10) with the reference system regardless of task or kinematic parameter. Moreover, Bland-Altman analyses indicated that there were no significant systematic errors present. This study indicates that upper limb movement kinematics can be accurately measured using the outREACH sensor, and have the potential to enhance stroke evaluation and rehabilitation in sub-Saharan Africa.
