Abstract
Embodiments of systems and methods for monitoring use of an orthopedic device are at least disclosed. In some embodiments, the system can include an orthopedic device, a housing, and a controller. The orthopedic device can provide support to a limb of an individual. The orthopedic device can include a magnet configured to generate a magnetic field. The housing can attach to the individual, and the housing can support a magnetometer configured to generate a signal responsive to the magnetic field. The controller can determine from the signal whether the individual is using the orthopedic device to provide support to the limb and accordingly output usage indications.
Claims20
A system for monitoring load bearing, the system comprising:
- a pressure source configured to provide pressure, via a fluid flow path, under a dressing configured to be positioned over at least a portion of a limb;
- a pressure sensor configured to monitor a pressure in the fluid flow path;
- a motion sensor configured to monitor a motion of the limb;
- and
- an electronic processing circuitry configured to:
- determine, from (i) a change in the pressure in the fluid flow path and (ii) a change in the motion, a duration of time over which the limb has been loaded to support a threshold weight;
- compare the duration of time to a duration threshold;
- and
- in response to a determination that the duration of time satisfies the duration threshold, output for presentation an indication that the limb should be offloaded.
