Force plates

Definition

Force plates are specialized devices used to measure the forces exerted by a body when it is in contact with the ground. They play a crucial role in biomechanics, as they help analyze human movement by quantifying parameters like ground reaction forces, center of pressure, and dynamic stability during various activities such as walking, running, or jumping.
