Single-arm position-matching results across all tested conditions.

Shown are the robotic assessment results on the single-arm position-matching task for the controls and participants with stroke. Mean (bar height) and standard error (error bars) of the (Top) constant error, (Middle) absolute error, and (Bottom) variable error are given as a function of the reference arm and reference target location for each classified group of participants. The gray dashed horizontal line indicates the deficit threshold of 10.7°. No significant effects were found. (Dom: dominant, Non-Dom: non-dominant, Non-Par: non-paretic, Par: paretic).
