The present invention is directed to a computer application for monitoring and tracking leg and foot movements and positions and a device for facilitating the computer tracking of the leg and foot movements. The application uses an accelerometer, gyroscope or other movement detectors in available devices such as a phone, movement tracker, personal music device, tablet computing device, other similar device or a device specifically designed to detect movements and positions and to track the movement and changes in position of the patient's leg and foot. The device can be held onto the patient's leg using a band type device that is easy to use and comfortable during sleep or by incorporation into a comfortable wearable band. The application includes a user interface and a backend for use by physicians or other healthcare staff to review and diagnose the patient's leg and foot movement patterns.
