Biomechanical changes to human locomotion due to asymmetric loading of the legs
The biomechanics of lower limb locomotion is a yet unknown mixture of neurological control and physical parameters. The current study explored attaching a rehabilitative anklebot to subjects walking on a treadmill and observed duration, kinematic, and electromyography data to determine the …

A Novel Highly Accurate Wireless Wearable Human Locomotion Tracking and Gait Analysis System via UWB Radios
Gait analysis is the systematic study of human walking. Clinical gait analysis is the process by which quantitative information is collected for the assessment and decision-making of any gait disorder. Although observational gait analysis is the therapist's primary clinical tool for describing the …

Analysis of human locomotion via entrainment to mechanical perturbations to the ankle during both treadmill and overground walking
Rehabilitation of human motor function is an issue of utmost significance affecting millions of Americans. Robot-aided therapy emerged as a promising method to meet the increasing demand for effective rehabilitation services. While robot-aided therapy for upper-extremity provides clinically-proven, …

Layer-wise Relevance Propagation and its Applications in Running Biomechanics
… has entered an era of ’big data’, where human locomotion data is generated rapidly and in large quantities. This poses new challenges because conventional analysis methods are ineffective in the presence of the myriad of interacting variables that describe human locomotion in contemporary …

Inductive Biases in Learning Hierarchical Abstractions for Bipedal Locomotion
Bipedal locomotion presents a complex challenge in the field of reinforcement learning (RL), due to the high dimensional state and action space. Hierarchical abstractions and inductive biases emerge as critical components in navigating this complexity, offering pathways for effective learning and …

EMG as a control parameter in lower limb prosthetics : surface vs. implanted electrodes
Human locomotion is controlled by complex neurological patterns. These patterns activate and synchronise the musculoskeletal system to enable efficient and graceful ambulation. A limb amputation results in a partial loss of the complex structure needed for human locomotion. Various prosthetic …

Design of a high torque, lightweight clutch for use in an exoskeleton to augment human running
The metabolic augmentation of human locomotion though the use of wearable exoskeletons is a complex and difficult goal. One exoskeleton architecture adds parallel elasticity to the user during stance phase to unload the user's muscles and joints. Critical to this design is the creation of a …

A leg exoskeleton simulator for design, sensing and control development
… have been developed in an effort to augment human locomotion for over a century. However, only two portable leg exoskeletal devices have shown a significant decrease in walking metabolism [35, 11], not to mention, no device that has shown effective assistance and biomimetic behavior across …

Models of entrainment of human walking
Stable human locomotion may be described as a non-linear limit cycle oscillator. This claim has been supported through the observation of dynamic entrainment and phase-locking to external mechanical perturbations applied at the ankle. Simple models have been developed in attempts to understand …

Analysis of walking and balancing models actuated and controlled by ankles
… torque is the most important actuator in normal human locomotion. I investigate the dynamics of simple models actuated by ankles alone. To assess the contribution of ankle actuation to locomotion, I first analyze the dynamics of some passive walkers without any joint torque. These passive walkers …
