This study aims to develop a telemedicine platform for self-motor rehabilitation and remote monitoring by health professionals, in order to enhance recovery in patients after hip replacement. The implementation of such a technology is justified by medical (improvement of the recovery process by the possibility to perform rehabilitation exercises more frequently), economic (reduction of the number of medical appointments and the time patients spend at the hospital), mobility (diminution of the transportation to and from the hospital) and ethics (healthcare democratization and increased empowerment of the patient) purposes. The Kinect camera is used as a Natural User Interface to capture the physical exercises performed at home by the patients. The quality of the movement is evaluated in real-time by an assessment module implemented according to a Hidden-Markov Model approach. The results show a high accuracy in the evaluation of the movements (92% of correct classification). Finally, the usability of the platform is tested through the System Usability Scale (SUS). The overall SUS score is 81 out of 100, which suggests a good usability of the Web application. Further work will focus on the development of additional functionalities and an evaluation of the impact of the platform on the recovery process.

在自然康复中使用自然用户界面的研究：髋关节假体患者的基于Web的应用程序

这项研究旨在开发一个远程医疗平台，以进行卫生保健专业人员的自我运动康复和远程监控，以提高髋关节置换术后患者的康复能力。这项技术的实施通过医疗（通过更频繁地进行康复锻炼的可能性来改善恢复过程），经济性（减少就诊次数和减少患者在医院的时间），流动性（减少医疗费用）来证明是合理的。目的（医疗保健民主化和增强患者权能）。Kinect相机用作自然用户界面，以捕获患者在家中进行的体育锻炼。机芯的质量通过根据Hidden-Markov模型方法实施的评估模块进行实时评估。结果表明运动评估的准确性很高（正确分类的92％）。最后，通过系统可用性量表（SUS）测试平台的可用性。总体SUS得分是81（满分100），表明Web应用程序的可用性很好。进一步的工作将集中在开发附加功能和评估平台对恢复过程的影响上。这表明Web应用程序具有良好的可用性。进一步的工作将集中在开发附加功能和评估平台对恢复过程的影响上。这表明Web应用程序具有良好的可用性。进一步的工作将集中在开发附加功能和评估平台对恢复过程的影响上。
