Correlation between impairment and motor performance during reaching tasks in subjects with spastic hemiparesis.

Objective: The main purposes of this study were to examine, in subjects with chronic hemiparesis following a stroke: (i) the correlations between tests of muscle tone, stiffness, spasticity, paresis and co-contraction, and (ii) the correlations of these tests and measurements of impairment to upper extremity motor performance.

Design: Prospective, cross-sectional, correlation matrix using sample of convenience.

Subjects: Thirteen subjects with chronic hemiparesis secondary to a cerebrovascular accident (stroke) were tested.
