Often, patients are prescribed a series of exercises or stretches to perform at home to supplement their therapy. Performing these exercises correctly without professional supervision is challenging – leading to poor compliance and even further injury. When doing these exercises at home patients often wonder if they are doing it right. Lack of feedback negatively impacts their compliance rate and results in a longer recovery period, costing more for the patients and insurance companies. Checkmoves is a low cost, PT monitoring system for the recovering patient. The system does motion tracking of the patient and provides real-time visual and audio feedback. this is accomplished by using the phone accelerometer, a computer, and a wearable device.
