Development of a Smart Hallway for Markerless Human Foot Tracking and Stride Analysis
Objective: In this research, a marker-less ‘smart hallway’ is proposed where stride parameters are computed as a person walks through an institutional hallway. Stride analysis is a viable tool for identifying mobility changes, classifying abnormal gait, estimating fall risk, monitoring...

Lower-limb amputees expend more energy to walk than non-amputees and have an elevated risk of secondary disabilities. Insufficient push-off by the prosthetic foot may be a contributing factor. We aimed to systematically study the effect of prosthetic foot mechanics on...

Multi-directional Ankle Impedance During Standing Postures
In this study, we estimated the multi-directional ankle mechanical impedance in two degrees-of-freedom (DOF) during standing, and determined how the stiffness, damping, and inertia vary with ankle angle and ankle torque at different postures...

Enhancing Mobility With Quasi-Passive Variable Stiffness Exoskeletons
Shoes were invented to provide user comfort using rubber soles, despite marginal improvement in human mobility. Unlike shoes, current lower-limb exoskeletons use fixed stiffness springs to store and recycle energy to improve mobility. However, the maximum kinetic energy a human...

Gait and Dynamic Balance Sensing Using Wearable Foot Sensors
Remote monitoring of gait performance offers possibilities for objective evaluation, and tackling impairment in motor ability, gait, and balance in populations such as elderly, stroke, multiple sclerosis, Parkinson’s, etc. This requires a wearable and unobtrusive system capable of estimating ambulatory...

Design and Validation of a Semi-Active Variable Stiffness Foot Prosthesis
This paper presents the design and validation of a novel lower-limb prosthesis called the Variable-Stiffness Foot (VSF), designed to vary its forefoot stiffness in response to user activity. The VSF is designed as a semi-active device that adjusts its stiffness...

Gestural Interaction and Visual Illusion for Lower Limbs’ Neuropathic Pain Treatment
Pain caused by a lesion or a disease affecting the somatosensory nervous system is known as Neuropathic pain. It has been shown that neuropathic pain can be treated with the combination of simultaneous transcranial direct current stimulation and the generation...

Energy-Optimal Human Walking With Feedback-Controlled Robotic Prostheses: A Computational Study
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 optimized robotic prosthesis. Here, we use large-scale trajectory optimization on a simulated transtibial amputee with...
