Abstract: After completion of cardiac rehabilitation, most patients return to their sedentary lifestyle. Previous studies have shown that repeated intervention by the rehabilitation team or dedicated nurse after program completion improves adherence to physical activity guidelines. The aim of this study was to evaluate different motion sensors for the assessment of habitual activity for cardiac patients following phase III cardiac rehabilitation. Motion sensors allow telemonitoring and internet-based interventions, a potentially time saving way to stimulate patients’ physical activity. We compared the estimated habitual activity assessed by a pedometer and an accelerometer for a duration of 4 weeks each, in a group of 10 coronary artery disease patients included in a phase III cardiac rehabilitation program. The daily exercise level was measured for each patient and compared with VO2 peak and ventilatory threshold as determined by ergospirometry at the end of the study. None of the measurements correlated with VO2 peak, but accelerometer recordings correlated significantly with the patient’s ventilatory threshold (i.e. the sub-maximal capacity), whereas those of the pedometer did not. A questionnaire concerning ease of use of the sensors obtained at the end of the monitoring period indicated that the cardiac patients favoured the pedometer.
