The use of kinetics as a marker for manual dexterity after stroke and stroke recovery.
Stroke is the leading cause of severe, long-term disability among older adults in the United States. Unimanual motor performance of the hemiparetic limb is clearly compromised, and these declines are well documented. An often overlooked aspect of motor function for patients with stroke is the effect of unilateral motor dysfunction on bimanual motor activities. Diminished bimanual function resulting from upper extremity hemiparesis necessarily limits the patient's daily functioning. In this review we describe a bimanual dexterity task that replicates many daily activities and outline how kinetic analysis of this task may provide insight into diminished bimanual function of patients with stroke and how these variables may be useful in assessing level of recovery and rate of motor recovery associated with behavioral interventions intended to improve upper extremity function. It is argued that the use of objective kinetic measures to quantify hand function may facilitate the clinical adoption of behavioral interventions for stroke, such as constraint-induced movement therapy and other repetitive task practice-based interventions.
