A new low-cost system for rehabilitation of the impaired upper limb for stroke survivors is presented. A computer game was developed specifically for this purpose and the user's impaired upper extremity is tracked using a downward-pointed Kinect, an inexpensive motion capture system commercially available from Microsoft. A Kalman filter was implemented to reduce data jittering. Patients are required to move their impaired arm, sliding it on top of a transparent support, in order to play the game. The game is personalized to the patient through specific settings that adapt to the patient's range of motion and motor control at the start of the game as well as performance during the game. The final score is proportional to the arm's movement speed. A feasibility study was carried out with one stroke survivor. The game was played for ten days and usability surveys were answered before and after the study. The patient was engaged with the game, found it easy to understand and reported willingness to use it in the home environment and enjoyment of the use in the clinic.
本文介绍了一种用于中风幸存者上肢功能康复的新型低成本系统。为此专门开发了一款电脑游戏，并使用向下指向的Kinect（微软公司商业化销售的一种廉价动作捕捉系统）来跟踪用户受损的上肢。实施了卡尔曼滤波器以减少数据抖动。患者需要移动其受损手臂，在透明支撑物上滑动，以便玩游戏。游戏通过特定设置进行个性化，这些设置在游戏开始时适应患者的运动范围和运动控制，以及游戏过程中的表现。最终得分与手臂的移动速度成正比。对一名中风幸存者进行了可行性研究。游戏进行了十天，并在研究前后进行了可用性调查。患者参与了游戏，发现它易于理解，并表示愿意在家庭环境中使用它，且在诊所使用时感到愉快。
