Walking can be exceedingly complex to analyze due to highly nonlinear multibody
dynamics, nonlinear relationships between muscle excitations and resulting muscle forces …

Over the last few decades, researchers have explored and enhanced the functionality of the
prosthetic foot. The amputees have a vast range of prosthetic foot from which they have to …

The regulation of whole-body angular momentum is important for maintaining dynamic
balance during human walking, which is particularly challenging in the frontal plane. Whole …

Mediolateral balance control during walking is a challenging task in post-stroke hemiparetic
individuals. To detect and treat dynamic balance disorders, it is important to assess balance …

This paper assesses the metabolic effort exerted by three transfemoral amputees, when
using a powered knee and ankle prosthesis for stair ascent, relative to ascending stairs with …

Lower-limb amputees typically experience reduced mobility and higher metabolic rates than
non-amputees. It may be possible to improve their mobility and metabolic rate with an …

Sloped walking requires altered strategies for maintaining dynamic balance relative to level-
ground walking, as evidenced by changes in sagittal-plane whole-body angular momentum …

Objective Unilateral trans-tibial amputation signifies a challenge to locomotion. Prosthetic
ankle-foot units are developed to mimic the missing biological system which adapts push-off …

Non-volitional control, such as finite-state machine (FSM) impedance control, does not
directly incorporate user intent signals, while volitional control, like direct myoelectric control …

During walking, the center of mass (CoM) position can be controlled relative to the base of
support by shifts of the center of pressure through modulation of foot placement and ankle …
