Wearable monitoring devices, such as smart bands, have emerged as accessible and non-invasive tools for assessing physiological and spatiotemporal gait parameters in various clinical tests. This study aimed to validate the use of the Xiaomi Mi Band 6 for recording gait parameters during the six-minute walk test (6MWT). Seventy participants without gait impairments were recruited, and the measurements obtained with the smart band were compared to reference methods (evaluator, pedometer, and pulse oximeter). The physiological parameter results showed that the smart band demonstrated good accuracy in heart rate monitoring but lower agreement in oxygen saturation measurements. Gait parameters indicated excellent agreement in step count (ICC > 0.9) and step frequency (ICC > 0.75), whereas step length and distance estimations showed higher variability. These findings suggest that the Xiaomi Mi Band 6 is a viable alternative for measuring specific gait parameters, though with limitations in certain aspects of accuracy.
可穿戴监测设备，如智能手环，已成为在各种临床试验中评估生理和时空步态参数的便捷且非侵入性的工具。本研究旨在验证小米手环6在六分钟步行试验（6MWT）期间记录步态参数的用途。招募了70名无步态障碍的参与者，并将智能手环获得的测量结果与参考方法（评估者、计步器和脉搏血氧仪）进行比较。生理参数结果表明，智能手环在心率监测方面显示出良好的准确性，但在血氧饱和度测量方面的一致性较低。步态参数表明，步数（ICC>0.9）和步频（ICC>0.75）的一致性极佳，而步长和距离估计的变异性较高。这些发现表明，小米手环6是测量特定步态参数的可行替代方案，尽管在准确性的某些方面存在局限性。
