Systems, devices, and methods for providing foot loading feedback to patients and physicians during a period of partial weight bearing
First Claim
1. A system for providing user feedback regarding compliance with a set of partial weight bearing (PWB) criteria including a load compliance range, the system including:
- a single load profile monitoring device that receives force data from a pressure sensor positioned adjacent to a substantially non-compressible pressure transmitter, wherein the single load profile monitoring device is sized and configured to measure a load profile in both a ball region of a foot and a heel region of the foot;
the substantially non-compressible pressure transmitter being configured to transfer force to the pressure sensor, wherein;
the substantially non-compressible pressure transmitter is positioned within a cavity of a housing,the pressure sensor is configured to float or otherwise move within the substantially non-compressible pressure transmitter to change location and/or orientation,the pressure sensor positioned;
at a non-parallel angle with respect to a bottom surface of the housing, andoffset from a line-of-action of a force applied to the housing; and
the housing comprises an aperture that provides a reference atmospheric pressure to the pressure sensor;
a processing module that accesses the force data received from the pressure sensor to determine whether the user is within a predefined load compliance range, the load compliance range specifying a prescribed range of load that is to be applied during a PWB period; and
a communications module that, upon receiving a compliance data request, communicates compliance data representing the user'"'"'s compliance with the prescribed range of load during the PWB period to at least one of the user and the user'"'"'s physician, wherein the user'"'"'s compliance is determined at a rate that is specified by a medical professional.

Abstract
Systems, devices, and methods for providing user feedback regarding compliance with a set of partial weight bearing (PWB) criteria are described. A computer system receives force data from a non-compressible force transmitter that is assigned to a user, and accesses the force data received from the non-compressible force transmitter to determine whether the user is within a predefined pressure compliance range. The pressure compliance range specifies a prescribed range of pressure that is to be applied during a PWB period. The computer system then receives a compliance data request from the user or the user'"'"'s physician and communicates compliance data representing the user'"'"'s compliance with the prescribed range of pressure during the PWB period to the user and/or the user'"'"'s physician.

16. A computer-implemented method for providing user feedback regarding compliance with a set of partial weight bearing (PWB) criteria, the method comprising:
-
receiving force data from a pressure sensor positioned in physical communication with a substantially non-compressible pressure transmitter that is assigned to a user, wherein; the substantially non-compressible pressure transmitter is positioned within a cavity of a housing, the pressure sensor comprises a piezoresistive pressure sensor that has been converted into a load sensor by packaging the piezoresistive pressure sensor in a silicone gel force-transduction media enclosed within a semi-rigid case, the pressure sensor is sized and configured to measure a load profile in both a ball region of a foot and a heel region of the foot, the pressure sensor is configured to float or otherwise move within the substantially non-compressible pressure transmitter to change location and/or orientation, the pressure sensor is positioned; at a non-parallel angle with respect to a bottom surface of the housing, and offset from a line-of-action of a force applied to the housing, and the housing comprises an aperture that provides a reference atmospheric pressure to the pressure sensor; accessing the force data received from the pressure sensor to determine whether the user is within a predefined load compliance range, the load compliance range specifying a prescribed range of load that is to be applied during a PWB period; receiving a compliance data request from the user or the user'"'"'s physician; and communicating compliance data representing the user'"'"'s compliance with the prescribed range of load during the PWB period to the user or the user'"'"'s physician, wherein the user'"'"'s compliance is determined at a rate that is specified by a medical professional. - View Dependent Claims (17, 18)

19. A computer system for gathering and storing force data to determine a user'"'"'s compliance with a predefined pressure compliance range comprising:
-
one or more processors; system memory; one or more computer-readable storage media having stored thereon computer-executable instructions that, when executed by the one or more processors, causes the computing system to perform at least the following; receive an indication that a period of partial weight bearing (PWB) has been initiated for a user; initiate a pressure sensor that is in physical communication with a substantially non-compressible pressure transmitter that is assigned to the user, wherein; the substantially non-compressible pressure transmitter is positioned both within a cavity of a housing oriented with respect to the user'"'"'s leg and adjacent to the pressure sensor to transmit pressure within the housing, the pressure sensor is configured to float or otherwise move within the substantially non-compressible pressure transmitter to change location and/or orientation, the pressure sensor is positioned; at a non-parallel angle with respect to a bottom surface of the housing, and offset from a line-of-action of a force applied to the housing, and the housing comprises an aperture that provides a reference atmospheric pressure to the pressure sensor; store, at specified intervals, one or more portions of force data sensed by the pressure sensor, the force data indicating the user'"'"'s compliance with a predefined pressure compliance range that is to be applied during the PWB period, wherein the specified intervals are specified by a medical professional; and upon receiving a request for stored force data, send the stored force data to the data requester.
