Abstract
The invention relates to method and system for monitoring musculoskeletal loading of a user during remote or longitudinal activity. The method includes collecting, by a primary sensor device operably attached to the user, primary sensor data indicative of biomechanical loading of a musculoskeletal tissue; collecting, by a secondary sensor device operably attached to the user, secondary sensor data indicative of physical activity of the user; synchronizing the primary sensor data with the secondary sensor data over a training interval; training, using the synchronized primary and secondary sensor data, a calibration model specific to the user to estimate a musculoskeletal loading metric from the secondary sensor data; and estimating, by applying the calibration model, the musculoskeletal loading metric during a period in which only the secondary sensor data is available.
