本文提出了一种新的评估系统，以及评估机器人辅助治疗前后日常生活活动中手臂功能的双侧协调性的方法。描述了一种负担得起的双边评估系统(BIAS)，该系统由两个小型被动测量单元组成，建模为三自由度机器人。介绍了使用偏差评估功能任务的过程，并演示了其测量腕部运动轨迹的能力。采用相位差、运动重叠和任务完成时间三个指标，对双边对称(双向饮酒)和双边非对称(双向倒灌)功能任务的偏向系统进行了评价。使用这些指标评估腕部位置和速度轨迹，以洞察中风后的时间和空间上的双侧缺陷。BIAS系统量化了手腕在功能任务中的运动，并检测了受损和未受损手臂运动的差异。案例研究表明，与健康受试者相比，中风患者移动速度较慢，即使在功能任务需要同时运动的情况下，也不太可能同时使用手臂。在机器人辅助治疗后，肢体间协调的空间缺陷在功能任务上转向正常的协调。
This article presents a novel evaluation system along with methods to evaluate bilateral coordination of arm function on activities of daily living tasks before and after robot-assisted therapy. An affordable bilateral assessment system (BiAS) consisting of two mini-passive measuring units modeled as three degree of freedom robots is described. The process for evaluating functional tasks using the BiAS is presented and we demonstrate its ability to measure wrist kinematic trajectories. Three metrics, phase difference, movement overlap, and task completion time, are used to evaluate the BiAS system on a bilateral symmetric (bi-drink) and a bilateral asymmetric (bi-pour) functional task. Wrist position and velocity trajectories are evaluated using these metrics to provide insight into temporal and spatial bilateral deficits after stroke. The BiAS system quantified movements of the wrists during functional tasks and detected differences in impaired and unimpaired arm movements. Case studies showed that stroke patients compared to healthy subjects move slower and are less likely to use their arm simultaneously even when the functional task requires simultaneous movement. After robot-assisted therapy, interlimb coordination spatial deficits moved toward normal coordination on functional tasks.
