Computational Control Strategy for Reducing Medial Compartment Load in Knee Bracing with Embedded Actuator

open access: yesActuators, 2023
Medial unloader braces represent a primary noninvasive approach for alleviating knee pain. However, conventional valgus unloader braces, while reducing load on the medial compartment, inadvertently increase load on the lateral compartment through ...
