A Stair Ascent and Descent Controller for a Powered Ankle Prosthesis
    This paper presents a control system for a powered transtibial prosthesis that provides stair ascent and descent capability, as well as ability for user-controlled transitions between walking, standing, stair ascent, and stair descent. The control system was implemented on a... Read more

Locomotor Adaptation by Transtibial Amputees Walking With an Experimental Powered Prosthesis Under Continuous Myoelectric Control
Lower limb amputees can use electrical activity from their residual muscles for myoelectric control of a powered prosthesis. The most common approach for myoelectric control is a finite state controller that identifies behavioral states and discrete changes in motor tasks.... Read more

Toward Balance Recovery with Leg Prostheses using Neuromuscular Model Control
Lower limb amputees suffer from decreased proprioception, balance, and a limited ability to respond to unexpected disturbances during locomotion. These deficiencies increase the risk of falling, leading to injuries and an aversion to physical activity. Robotic prostheses that use motors... Read more

Variable Cadence Walking and Ground Adaptive Standing With a Powered Ankle Prosthesis
This paper describes a control approach that provides walking and standing functionality for a powered ankle prosthesis, and demonstrates the efficacy of the approach in experiments with a unilateral transtibial amputee subject. Both controllers incorporate a finite-state structure that emulates... Read more
