NSF CMMI 1762211           (2018-2021)

Collaborative Research: Enhancing Gait Dynamics via Physical Human-human and Human-Robot Interactions at the Hands

PI: Lena Ting; co-I: Madeleine Hackney

To understand how small forces applied to the hand can be used to alter clinically-relevant human gait patterns: Stage 1, the project team will measure interactive human-to-human hand forces and the resulting gait motions that occur during the proposed therapeutic intervention.

NSF CMMI 1761679            (2018-2021)

Collaborative Research: Enhancing Gait Dynamics via Physical Human-human and Human-Robot Interactions at the Hands

PI: Irfan Essa; co-PI: Jun Ueda

To understand how small forces applied to the hand can be used to alter clinically-relevant human gait patterns: Stage 2, the project team will develop a model of the motor and cognitive transformations that occurred during Stage 1. They will then embed the models within a novel robotic test-bed to implement physical human-robot interactions at the hands.
