Disclosed is a wearable physical therapy data collection system. The system includes a wearable support having a waistband and at least one motion detector assembly. The motion detector assembly includes a femoral strut extending between a superior end and an inferior end; a polyaxial connection between the superior end and the waistband; and hip sensors in motion sensing communication with the polyaxial connection, configured to capture data reflecting movement of the femur with respect to the hip in the medial—lateral direction, anterior—posterior direction and rotation of the femur. A tibial strut may extend between the inferior end and a polyaxial connection to a foot attachment. Sensors may be provided to capture data reflecting tibial rotation, and flexion, extension, rotation and pronation of the foot. Separate left and right motion detectors enable collection of bilateral data, to identify bilateral imbalances and monitor rehabilitation progress.

In some aspects, a non-transitory computer readable medium is disclosed that has an application stored thereon that when executed by a processor of an electronic device causes the processor to perform a process. The process can include receiving motion data from a motion sensor, the motion data being indicative of motion by a user while wearing the motion sensor. The process can also include transmitting the motion data to a server, receiving from the server a time that the motion data indicates a foot of the user experienced a loading force which risked adversely impacting an existing foot ulcer or causing a new foot ulcer, determining a geographic location of the motion sensor at the time that the foot experienced the loading force, displaying the time and the geographic location, and requesting that the user identify an activity engaged in by the user at the time and the geographic location.

In order to provide a wearable device that enables determining with high accuracy whether the wearable device is mounted on a living body or a fitting to be worn by a living body, the wearable device includes a base member, a receiving quality index acquisition unit, a sensor, and a transmitter. The receiving quality index acquisition unit receives a GPS signal, and acquires a receiving quality index of the GPS signal.
