Wearable device to monitor musculoskeletal loading, estimate tissue microdamage and provide injury risk biofeedback

A wearable device configured to be operably worn by a user for monitoring ankle moment, calf muscle force, and/or Achilles tendon force, comprising:

• a plurality of sensors, each sensor configured to be operably worn by the user to detect information about a biomechanical activity, the plurality of sensors comprising one or more force sensors configured to be located under a foot of the user, and one or more motion sensors configured to be located on the foot and/or shank segment of the user;
• and
• a processing unit in communication with the plurality of sensors and configured to process the detected information by the plurality of sensors to estimate the ankle moment, calf muscle force, and/or Achilles tendon force by combining force magnitude and center of pressure data from the one or more force sensors with body segment orientation data derived from the one or more motion sensors, and communicate the estimated ankle moment, calf muscle force, and/or Achilles tendon force to the user and/or a party of interest.
