Abstract: Measured forces applied by a medical professional during a gap assessment can be measured. A plurality of force sensors is placed at a lateral ankle position, a medial ankle position, a lateral foot position, and/or a medial foot position, and each detects an applied force during an abduction-adduction examination. Further, a computing device receives, from each of the plurality of sensors during the abduction-adduction examination, data representing an applied force occurring during the abduction-adduction examination at respective ones of the lateral ankle position, the medial ankle position, the lateral foot position, and the medial foot position. The computing device calculates, using the received data, respective peak applied forces during the abduction-adduction examination in extension and flexion, and provides information representing a correlation of the respective peak applied forces with other information.
