Wearable devices have been showing promising results in a large range of applications: since industry, to entertainment and, in particular, healthcare. In the scope of movement disorders, wearable devices are being widely implemented for motor symptoms objective assessment. Currently, clinicians evaluate patients' motor symptoms resorting to subjective scales and visual perception, such as in Parkinson's Disease. The possibility to make use of wearable devices to quantify this disorder motor symptoms would bring an accurate follow-up on the disease progression, leading to more efficient treatments.Here we present a novel textile embedded low-power wearable device capable to be used in any scenario of movement disorders assessment due to its seamless, comfort and versatility. Regarding our research, it has already improved the setup of a wrist rigidity quantification system for Parkinson's Disease patients: the iHandU system. The wearable comprises a hardware sensing unit integrated in a textile band with an innovative design assuring higher comfort and easiness-to-use in movement disorders assessment. It enables to collect inertial data (9-axis) and has the possibility to integrate two analog sensors. A web platform was developed for data reading, visualization and recording. To ensure inertial data reliability, validation tests for the accelerometer and gyroscope sensors were conducted by comparison with its theoretical behavior, obtaining very good results.
从工业到娱乐，尤其是医疗保健领域。在运动障碍范畴内，可穿戴设备正被广泛用于运动症状的客观评估。目前，临床医生评估患者的运动症状时依赖主观量表和视觉感知，比如在帕金森病的诊断中。利用可穿戴设备量化这种疾病的运动症状，将能对疾病进展进行精确跟踪，从而实现更有效的治疗。在此，我们展示一款新型的嵌入纺织品的低功耗可穿戴设备，因其无缝贴合、舒适且多功能，能够用于运动障碍评估的任何场景。关于我们的研究，它已经改进了针对帕金森病患者的手腕僵硬量化系统——iHandU系统的设置。该可穿戴设备包括一个集成在纺织带中的硬件传感单元，其创新设计确保在运动障碍评估中具有更高的舒适度和易用性。它能够收集惯性数据（九轴），并且有可能集成两个模拟传感器。还开发了一个网络平台用于数据读取、可视化和记录。为确保惯性数据的可靠性，通过与理论行为进行比较，对加速度计和陀螺仪传感器进行了验证测试，取得了非常好的结果。
