Directional Mechanical Impedance of the Human Ankle During Standing with Active Muscles

Guilherme A. Ribeiro, Lauren N. Knop, Mo Rastgaar

ICRA 2020poster

The directional mechanical impedance of the human ankle was identified from subjects in a standing posture with varying levels of muscle activity. The impedance modeled the different torque responses to angle perturbations about different axes of rotation. This work proposed a novel impedance model…

Time-varying human ankle impedance in the sagittal and frontal planes during stance phase of walking

Evandro M. Ficanha, Guilherme A. Ribeiro, Lauren Knop, Mo Rastgaar

ICRA 2017poster

This paper, for the first time, describes the estimation of the time-varying impedance of the human ankle in the sagittal (SP) and frontal (FP) planes during the stance phase of walking. The result of this work is aimed to provide design parameters for the development of 2-DOF powered ankle-foot pro…
