Abstract
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.

1.1 Dynamic accuracy details
The trackers were attached to the robot end-effector and moved along eight trajectories; the adjusted forward kinematics equations were used to calculate corresponding position trajectories. The difference between the measured and reference trajectories were calculated over the constant velocity segments within the trajectory and then averaged across all samples; there were approximately 250 samples. Table 5 shows that the best accuracy was seen in the X coordinate for all speeds. The differences in positions were not significant (P = 0.62).
