Mobile Phone-Connected Wearable Motion Sensors to Assess Postoperative Mobilization.

We provide one of the first assessments of the accuracy and utility of widely available and wirelessly connected activity sensors in a postoperative patient population. Our results show that activity sensors are able to provide invaluable information about a patient's mobility status and can transmit this data wirelessly, although there is a systematic underestimation bias in more debilitated patients.
