A patient rehabilitation system to provide real-time joint motion data to assess the capability of a joint, the system comprises a wearable sensor for providing real-time joint range of motion data, the sensor is stand-alone whereby only one sensor is needed to measure multiplanar movement at a single joint, the sensor comprises a combination of a tri-axial accelerometer, a tri-axial goniometer and a tri-axial magnetometer, the sensor continuously reports its orientation about its own internal tri-axial frame, and the sensor comprises firmware to interpret raw signals from these constituent components in order to derive angular orientation data for the sensor about each of three mutually orthogonal axes, the system comprises associated software, in which data is collected and transmitted from the sensor in real time and a visual demonstration of range of movement achieved is provided, and in which precise locational data provided by the sensor together with the associated software allows for an exact replication ofjoint movement to be shown to the patient to ensure compliance with a rehabilitation schedule.

A method to provide real-time joint range of motion data comprising use of a standalone sensor positioned in an area of a subject to monitor that area and/or to monitor a site distant/remote from a physical sensor location, the method comprising the step of positioning a sensor at a known initial orientation and then subsequently reporting changes in angular orientation of the sensor relative to the initial orientation without reference to any other sensor, the sensor comprises a combination of a tri-axial accelerometer, a tri-axial goniometer and a tri-axial magnetometer, the sensor continuously reports its orientation about its own internal tri-axial frame, and the sensor comprises firmware to interpret raw signals from these constituent components in order to derive angular orientation data for the sensor about each of three mutually orthogonal axes.
