Abstract: Disclosed is a computer-implemented method. The method comprises processing, by at least one computing device, exercise measurements taken by a pressure sensor positioned adjacent to a pelvic floor muscle (PFM) of a person at least during performance of a physical exercise, wherein the exercise measurements are indicative of a pressure exerted on the pressure sensor and an orientation of the sensor. The method also comprises calibrating, by the at least one computing device, the pressure of the processed exercise measurements at least based on the orientation of the processed exercise measurements.

Abstract: Disclosed is a computer-implemented method. The method comprises processing, by at least one computing device, first measurements taken at least while a person performs a predetermined physical exercise, wherein the first measurements are taken by at least one motion tracking device, at least one optical sensor, or both. The method also comprises processing, by the at least one computing device, second measurements taken at least while the person performs the predetermined physical exercise, wherein the second measurements are taken by a pelvic sensor. The method also comprises determining, by at least one computing device, whether the person has performed the predetermined physical exercise based on the first measurements and the second measurements according to criteria associated with the predetermined physical exercise.

Abstract: A method for physical exercise using a motion tracking system having a computing device and inertial measurement units adapted to be arranged on body members of a person. The method includes: digitally processing first sets of measurements provided by the units to determine whether and adjust the operation of the motion tracking system when: any of the units is arranged on a body member with an orientation outside of a predetermined orientation range for a unit on that body member; and/or two or more units arranged on interchanged body members according to the predetermined unit arrangement; adjusting the operation of the motion tracking system when the computing device determines, based on at least the first sets of measurements, that: at least one unit has an orientation outside of the predetermined orientation range, and/or two or more units are arranged on interchanged body members; and digitally processing second sets of measurements.

Abstract: A method for determining cause of a disconnection between a computing device of a motion tracking system and one or more sensors of the system, the sensors arranged on a person's body, the computing device configured to at least receive data through a wireless communications connection. Each sensor is configured to at least transmit data through the connection. The method includes measuring a signal strength of the connection with each sensor while the communications are established; processing signal strength values corresponding to a sensor when it has been disconnected from the computing device to determine if the sensor has been disconnected due to a distance increase between the person and computing device; and providing or commanding the provision of at least one user perceptible signal when the computing device has determined that at least one sensor has been disconnected due to a distance increase between the person and computing device.
