H-Man, planar robot is, used for this purpose. Thirteen healthy and two chronic stroke patients with upper limb motor impairment participated in the study. Assessment of performance was made through three task parameters (smoothness of movement, peak velocity, and time to peak velocity). The results from healthy subjects indicate no significant difference between different directions, however significant differences are observed in stroke participants across different directions for smoothness measure (Spectral Arc Length). All the three measures show significant differences between control and Stroke participants for corresponding directions.

This paper first presents H-Man, a low cost planar robot, as a quantitative assessment and training tool. This is followed by a preliminary study to investigate baseline performance measures for motor assessment during reaching tasks as a step toward replacing conventional ordinal scales with continuous quantitative scales. Thirteen healthy and one participant with upper limb motor impairment participated in the study and performed reaching tasks with their dominant and non-dominant hands in three directions. The results from healthy subjects indicate no significant difference between different directions for both limbs and also between corresponding directions of dominant and non-dominant limbs (p > 0.05, all cases). However, differences in measures can be observed for the impaired subject.
