Activity capability monitoring

A method of monitoring activity capabilities of a subject, the method including, in at least one processing device:

• a) determining sensor data indicative of sensor readings for each of a plurality of sensors, the sensors being mounted in a living environment of the subject and the sensor data for each sensor being at least partially indicative of one or more activities performed by the subject;
• b) for each of a plurality of activity domains, determining a domain score indicative of a level of activity within the respective activity domain, the domain score being determined using sensor data from a respective combination of sensors associated with the respective domain;
• c) determining a reference activity level using reference domain scores measured during a reference time period, wherein the reference domain scores are determined using the sensor data from the sensors mounted in the living environment of the subject during a reference time period;
• d) determining a current activity level using current domain scores measured during a monitoring time period;
• e) generating an activity indicator at least partially in accordance with the current activity level and the reference activity level, the activity indicator being at least partially indicative of differences between the current activity level and the reference activity level, thereby providing feedback on the activity capabilities of the subject;
• f) comparing the current activity level to the reference activity level that is measured during the reference time period, such that the current activity level as measured on a given day is compared to a reference activity level established for the same day during the reference time period;
• and,
• g) determining an activity level score based on results of comparing the current activity level to the reference activity level, wherein the activity level score is a single numerical overall score indicating a functional independence of the subject.

An apparatus for monitoring activity capabilities of a subject, the apparatus including:

• a) a plurality of sensors, the sensors being mounted in a living environment of the subject;
• and,
• b) at least one processing device that:
• i) determines sensor data indicative of sensor readings for each of the plurality of sensors, the sensor data for each sensor being at least partially indicative of one or more activities performed by the subject;
• ii) for each of a plurality of activity domains, determines a domain score indicative of a level of activity within the respective activity domain, the domain score being determined using sensor data from a respective combination of sensors associated with the respective domain;
• iii) determines a reference activity level using reference domain scores, wherein the reference domain scores are determined using the sensor data from the sensors mounted in the living environment of the subject during a reference time period;
• iv) determines a current activity level using current domain scores measured during a monitoring time period;
• v) generates an activity indicator at least partially in accordance with the current activity level and the reference activity level, the activity indicator being at least partially indicative of differences between the current activity level and the reference activity level, thereby providing feedback on the activity capabilities of the subject;
• vi) compares the current activity level to a reference activity level that is measured during the reference time period, such that the current activity level as measured on a given day is compared to a reference activity level established for the same day during the reference time period;
• and,
• vii) determines an activity level score based on results of comparing the current activity level to the reference activity level, wherein the activity level score is a single numerical overall score indicating a functional independence of the subject.
