Medio-lateral gait stability and fall risk in older adults
… the use of medio-lateral (ML) jerk to assess gait stability of older adults (OAs) with and without a fall history. Current research is unable to identify individuals at risk of falling prior to their first fall. There is also the identification and summary of common laboratory methods used in …

Characterising intra- and inter-limb gait stability using minimum foot clearance
… effects by characterising one parameter of the gait cycle from treadmill walking. The minimum foot clearance (MFC) during the swing phase of gait is an essential event that reveals two things: 1) how the locomotor system achieves control over many degrees of freedom when performing this spatial …

Quantifying gait stability based on body segment coordination relationships measured with wireless sensors
… these relationships can be used to characterize gait stability in persons with MS (PwMS). In Aim 1, we determined how segment relationships are affected by changing walking speed and sensory input in PwMS compared to healthy controls. PwMS and healthy age-matched controls walked on a treadmill at …

Stable locomotion control of bipedal walking robots : synchronization with neural oscillators and switching control
… are studied for achieving bipedal locomotion stability. Postural stability is realized by structural dynamics shaping, and gait stability is achieved by synchronization with neural oscillators and switching control. A biologically inspired control with neural oscillators (central pattern …

The acute and chronic effects of resistance exercise with and without blood flow restriction on fall risk factors in older adults
… quiet standing (double leg and single leg) and gait stability (walking) after performing a fatiguing exercise protocol to either the ankle or knee in healthy young adults. There were minimal changes to quiet standing and gait stability post-exercise for either the ankle or knee irrespective of …

Development and validation of a functional outcome measure package for total knee arthroplasty
… knee range of motion (ROM), knee strength, gait kinematics, and gait stability were incorporated into the software. Most results were reported in real-time. Validation studies of the assessments against clinical standard tools showed few clinically significant differences between the …

Perturbation-based detection and prosthetic correction of vestibulopathic gait
… prevent fall-related injuries due to postural instability, it is important to create both diagnosis techniques so that therapy can be applied before a fall occurs and devices which can aid the balance-impaired population. The aims of this research are twofold: 1) to develop metrics that quantify …

Perception and control of robot legged locomotion over variable terrain
… methods are shown empirically to increase gait stability and to reduce impact loading on the legs. To the best of our knowledge, the work demonstrates the first example of a running controller that measures changes in stiffness of the ground and modifies its controller within a single …

Visual servo control on a humanoid robot
… locomotion, conditioned by postural balance and gait stability, is studied. The presented approach is formulated to account for all the joints of the biped robot. As a way to conform the reference commands from visual servoing to the discrete locomotion mode of the robot, this study exploits a …

From Lab to Outdoors: The Effects of Terrain, Environment, Amputation level, and Prosthetic Knee Type on Gait
… technology, a greater understanding of amputee gait is needed, especially among amputees in developing countries. Field studies as well as prosthesis technology in developing countries are limited due to barriers associated with equipment and resources availability. Furthermore, individuals with …

Assessing the Effects of Exoskeleton Use on Balance and Postural Stability
… and to what extent, BSE use alters postural stability and/or fall risk. The primary goal of this work was to understand the effects of exoskeleton use, and quantify the effects of exoskeleton design parameters, on balance and postural stability, with a focus on passive BSEs used for …
