The authors determined the reliability and validity of the Four-Point Pusher Score (4PPS) among stroke survivors. Stroke survivors were invited to participate within 48 hours of admission to a stroke rehabilitation unit in a tertiary hospital. Intrarater reliability was determined by examining scores assigned to the same patient by the same physiotherapist.
