  • Systems and methods for a multi-axis robotic platform for studying neuromechanics of an ankle joint
    Patent number: 10850389
    Abstract: A multi-axis robotic platform for studying neuromechanics comprises a bottom plate, a middle plate, and a top plate is disclosed herein. The middle plate is movably coupled between the bottom plate and the top plate. The top plate comprises a support surface for receiving an ankle. A first actuator is disposed upon the bottom plate and is connected to the middle plate via a first coupling such that a shaft of the first actuator rotates the middle plate along a dorsiflexion-plantarflexion (DP) axis of the ankle. A second actuator is disposed upon the middle plate and is connected to the top plate via a second coupling such that a shaft of the second actuator rotates the top plate along an inversion-eversion (IE) axis of the ankle. The multi-axis robotic platform can analyze ankle impedance and reflex characteristics in two degrees-of-freedom (DP movement and IE movement) during postural and locomotion tasks.
