1. A system for assessing and improving adherence of a user in wearing at least one of footwear, braces, or orthotics, or using walking-aid devices, the system comprising:
- a sensor configured to be worn by said user, said sensor comprising one or more accelerometers; and
one or more tagged devices identified by one or more radio-frequency tags and comprising one or more accelerometers;
wherein said system is configured to;
detect whether said user is wearing said sensor at least partly in response to measurements of respiration fluctuation of said user using said one or more accelerometers of the sensor; and
detect that said user is not wearing said one or more tagged devices at least partly by identifying instants or time periods when;
said one or more tagged devices are not detected by said sensor to be within a predefined distance of said sensor and measurements from said sensor indicate that said user undergoes a pre-specified foot-loading condition;
ormeasurements from said sensor indicate that said user is walking, said one or more tagged devices are detected by said sensor to be within said predefined distance of said sensor, and measurements from said one or more accelerometers of said one or more tagged devices do not indicate that said user is walking.

Abstract
A system is provided for monitoring whether a user is wearing and/or using a tagged device such as prescribed footwear, a walking aid, a brace or other orthotics. The system may detect whether the user is using a tagged device and can, in some embodiments, alert the user or the user'"'"'s caregivers if the user ambulates without using the tagged device.

6. A body movement monitoring system comprising:
-
a sensor configured to be on a part of a body of a person, the sensor comprising; at least a first accelerometer configured to generate at least one first signal indicative of acceleration corresponding to a movement of the body of the person; and one or more processor circuits programmed to; process the at least one first signal to detect a foot-loading condition of the person; determine whether a device usable by the person for treating a medical condition is within range of the sensor while the person is engaged in the foot-loading condition; and in response to determining that the device is not within range of the sensor during the detected foot loading condition, determine that the person is out of compliance with a treatment regimen associated with using the device. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method of determining, by one or more processor circuits, compliance with a treatment regimen associated with a device, the method comprising:
-
processing one or more signals from at least a first accelerometer of a sensor worn by a person to detect that the person is engaged in a foot-loading condition; determining whether a device usable by the person for treating a medical condition is within range of the sensor while the person is engaged in the foot-loading condition; and in response to determining that the device is not within range of the sensor while the person is engaged in the foot-loading condition, determining, by one or more processor circuits, that the person is out of compliance with a treatment regimen associated with using the device. - View Dependent Claims (19, 20, 21)
