Reproducibility of cerebral and peripheral haemodynamic responses to active, passive and motor imagery paradigms in older healthy volunteers: A fTCD study

► Sensorimotor paradigms assess the integrity of haemodynamic responses. ► Distinguish between haemodynamic changes related to the stimulus and any day-to-day variability. ► We measured CBFv response during active, passive and motor imagery paradigms on different occasions. ► Patterns of haemodynamic responses revealed substantial reproducibility. ► Findings have implications for study design assessing the haemodynamic changes following ageing and in disease.
