Single-arm position-matching results for each participant across all tested conditions.

Shown are the robotic assessment results on the single-arm position-matching task for the controls and participants with stroke. Each participant’s (Top) constant error, (Middle) absolute error, and (Bottom) variable error are given as a function of the reference arm and reference target location. (Dom: dominant, Non-Dom: non-dominant, Non-Par: non-paretic, Par: paretic).
