Spatial coordination of PIP₂ and MCP₂ joints under the five exotendon loading conditions (LC₁-LC₅) and during voluntary movements: mean (SD) values of (a) PIP₂:MCP₂ ratio RPM of the stroke and control subjects, (b) correlation coefficient (r) of the stroke and control subjects, and (c) mean (SD) of the PIP₂ and MCP₂ joint angles of the stroke subjects.
