1. A computer-implemented method for monitoring a gait associated with one or more lower extremities, the method comprising:
receiving image data captured by one or more image sensors, the image data including a plurality of images depicting one or more lower extremities moving based on a care protocol and over a time period;
receiving inertial sensor data from one or more inertial sensors positioned on the one or more lower extremities;
receiving computer vision data including data representing at least a portion of the one or more lower extremities;
correlating the computer vision data over the time period with the received image data corresponding to the received inertial sensor data;
identifying, based on the correlation, the one or more lower extremities;
measuring, based on the image data or the computer vision data, one or more gait parameters associated with the identified one or more lower extremities moving during the time period;
determining, based on the one or more gait parameters, a movement pattern of the one or more lower extremities;
determining a sensor confidence level based on one or more characteristics of the inertial sensor data;
determining an updated movement pattern or an updated gait condition based on the one or more characteristics of the inertial sensor data in response to determining that the sensor confidence level is above a predefined threshold;
outputting the updated movement pattern or the updated gait condition of the one or more lower extremities; and
adjusting the care protocol for a user based on the output.
