This letter introduces a quasi-passive variable stiffness ankle ... does not require high-power actuators but instead relies on a clutch and elastic component to mimic the interaction between muscles ...

This paper proposes a new compliance control method of a soft ankle rehabilitation ... necessary actuator stiffness that the robot system should achieve to complement the subject’s own active efforts.

The results of the first analysis showed that only the variable maximum passive ankle dorsiflexion contributed significantly (F1,26=8.9, p=0.006) to calf muscle stiffness as quantified ... Alfred ...

Detailed information at joint and muscle levels provided in this human–machine system can contribute to the controller design optimization of assistive exoskeletons for rehabilitation and movement ...

In this article, first, a reconfigurable variable stiffness actuator with passive nonlinear variable stiffness and active variable stiffness characteristics is proposed to improve the adaptability and ...
