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, the dressing being configured to be positioned over at least a portion of a foot;
- a pressure sensor configured to monitor a pressure in the fluid flow path;
- a motion sensor configured to monitor a motion of the foot;
- and
- a controller 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 foot has been loaded to support a threshold weight;
- and
- output the duration of time for presentation.
A method for monitoring load bearing, the method comprising:
- providing, by a pressure source, pressure via a fluid flow path under a dressing positioned over at least a portion of a foot;
- monitoring, by a pressure sensor, a pressure in the fluid flow path;
- monitoring, by a motion sensor, a motion of the foot;
- and
- at a first time:
- by a controller, determining, 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 a foot has been loaded to support a threshold weight;
- and
- outputting the duration of time for presentation.
A system for monitoring load bearing, the system comprising:
- a pressure source configured to provide pressure via a fluid flow path under a dressing, the dressing being 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
- a controller 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;
- and
- output the duration of time for presentation.
