ABSTRACT

This study investigated the initiation and release of hand grasp in individuals with post-stroke hemiparesis. The study included 10 individuals with mild hemiparesis and 10 age- and sex-matched control subjects. Participants were instructed to grasp and release the bottle-like handle of a manipulandum with their affected hand when prompted by auditory cues. Data points related to the initiation and release of the grasp, the maximal grip force, and the time of maximal force were analyzed with the wrist at each of five angles: flexion at 30° and 60°, neutral at 0°, and extension at 30° and 60°. The post-stroke group required more time than the control group to release the grasp. No significant differences were observed between groups for other data points. The results may suggest that the delayed grasp release remains a residual deficit even in patients with well-recovered hand function after stroke.
