Many studies have reported the use of wearable devices to acquire biological data for the diagnosis and treatment of various diseases. Balance dysfunction, however, is difficult to evaluate in real time because the equilibrium function is conventionally examined using a stabilometer installed on the ground. Here, we used a wearable accelerometer that measures head motion to evaluate balance and examined whether it performs comparably to a conventional stabilometer. We constructed a simplified physical head-feet model that simultaneously records "head" motion measured using an attached wearable accelerometer and center-of-gravity motion at the "feet", which is measured using an attached stabilometer. Total trajectory length (r = 0.818, p -false discovery rate [FDR] = 0.004) and outer peripheral area (r = 0.691, p -FDR = 0.026) values measured using the wearable device and stabilometer were significantly positively correlated. Root mean square area values were not significantly correlated with wearable device stabilometry but were comparable. These results indicate that wearable, widely available, non-medical devices may be used to assess balance outside the hospital setting, and new approaches for testing balance function should be considered.
许多研究报告了使用可穿戴设备获取生物数据以诊断和治疗各种疾病。然而，由于平衡功能通常使用安装在地面上的平衡器进行检查，因此很难实时评估平衡功能障碍。在这里，我们使用了一种可穿戴加速度计来测量头部运动，以评估平衡，并检查它是否与传统的平衡器表现相当。我们构建了一个简化的物理头部-脚部模型，该模型同时记录使用附接的可穿戴加速度计测量的“头部”运动和使用附接的平衡器测量的“脚部”重心运动。使用可穿戴设备和平衡器测量的总轨迹长度（r=0.818，p-错误发现率[FDR]=0.004）和外周面积（r=0.691，p-FDR=0.026）值呈显著正相关。均方根面积值与可穿戴设备平衡仪没有显著相关性，但具有可比性。这些结果表明，可穿戴的、广泛可用的非医疗设备可用于评估医院环境外的平衡，应考虑新的平衡功能测试方法。
