帕金森病患者多节点运动监测可穿戴设备

Wearable Devices for Movement Monitoring of Patients with Parkinson's Disease

运动症状定量评估是帕金森病临床精准诊疗和长期管理的关键,帕金森病定量评估技术难点在于实现多信息、微负荷、长时程、大活动范围的运动监测。本文研制了一套用于帕金森病定量评估的多节点运动信息监测可穿戴设备,采用五个微型传感器节点实现上、下肢和腰部的多身体部位运动信息同步监测;同时基于微功耗Wi-Fi技术构建大范围无线传感网,实现多传感器数据远距离无线传输;并且研发了多线程同步传输的长时程数据采集软件。传感器节点体积为39mm×33mm×16mm,重量18g,工作时长12h,无线数据传输距离为45m。经帕金森病患者和正常人群测试,设备可在医院等复杂场景下实现可靠运动监测。

Quantitative assessment of the symptoms of Parkinson＇s disease is the key for precise diagnosis and treatment and essential for long term management over years. The challenges of quantitative assessment on Parkinson＇s disease are rich information, ultra-low load, long term and large range monitoring in free-moving condition. In this paper, we developed wearable devices with multiple sensors to monitor and quantify the movement symptoms of Parkinson＇s disease. Five wearable sensors were used to record motion signals from bilateral forearms, legs and waist. A local area network based on low power Wi-Fi technology was built for long distance wireless data transmission. A software was developed for signal recording and analyzing. The size of each sensor was 39 mm×33 mm×16 mm and the weight was 18g. The sensors were rechargeable and able to run 12 hours. The wireless transmission radius is about 45 m. The wearable devices were tested in patients and normal subjects. The devices were reliable and accurate for movement monitoring in hospital.
