Individual limb mechanical analysis of gait following stroke
JOURNAL OF BIOMECHANICS, 48(6), 984–989.
author keywords: Stroke; Hemiplegia; Rehabilitation; Gait; Mechanics
MeSH headings : Aged; Chronic Disease; Exercise Test; Extremities / physiopathology; Female; Gait / physiology; Humans; Male; Middle Aged; Stroke / physiopathology; Walking / physiology
TL;DR:
Comparison of individual limb mechanical gait asymmetries during the step-to-step transitions, single-support and over a complete stride between two groups of individuals following stroke stratified by gait speed suggests that limb power output may be dominated by vertical components, which are required for upright support.

2015 journal article
Revisiting the mechanics and energetics of walking in individuals with chronic hemiparesis following stroke: from individual limbs to lower limb joints
JOURNAL OF NEUROENGINEERING AND REHABILITATION, 12.
author keywords: Locomotion; Individual limbs method; Mechanical power; Metabolic power; Joint power; Inverse dynamics; Stroke
MeSH headings : Aged; Ankle Joint / physiopathology; Biomechanical Phenomena; Calorimetry, Indirect; Chronic Disease; Energy Metabolism; Female; Gait; Hip Joint / physiopathology; Humans; Joints / physiopathology; Knee Joint / physiopathology; Locomotion; Lower Extremity / physiopathology; Male; Mechanical Phenomena; Middle Aged; Paresis / etiology; Paresis / physiopathology; Self-Help Devices; Stroke / complications; Stroke / physiopathology
TL;DR:
A comparison of the mechanics and energetics of hemiparetic and unimpaired walking at a matched speed highlighted the need to target improving paretic ankle push-off via therapy or assistive technology in order to reduce the metabolic cost of hemIParetic walking.

2014 journal article
More is not always better: modeling the effects of elastic exoskeleton compliance on underlying ankle muscle-tendon dynamics
BIOINSPIRATION & BIOMIMETICS, 9(4).
author keywords: elastic ankle exoskeleton; muscle-tendon interaction; mechanics; energetics; hopping; ultrasound
MeSH headings : Biomimetics / instrumentation; Computer Simulation; Computer-Aided Design; Elastic Modulus / physiology; Equipment Design; Equipment Failure Analysis; Humans; Man-Machine Systems; Models, Biological; Movement / physiology; Muscle Contraction / physiology; Muscle, Skeletal / physiology; Orthotic Devices; Robotics / instrumentation; Tendons / physiology
TL;DR:
A simple, predictive model of human neuromechanical adaptation to a passive elastic exoskeleton applied at the ankle joint during a functional task concluded that both of these outcomes cannot be achieved simultaneously, and that one must come at the detriment of the other in a spring-assisted compliant MTU.

2014 journal article
Musculoskeletal modelling deconstructs the paradoxical effects of elastic ankle exoskeletons on plantar-flexor mechanics and energetics during hopping
JOURNAL OF EXPERIMENTAL BIOLOGY, 217(22), 4018–4028.
author keywords: Assistive robotics; Dynamics simulation; Energetics; Locomotion; Metabolic energy; Muscle mechanics
MeSH headings : Adult; Ankle Joint / physiology; Biomechanical Phenomena; Electromyography; Energy Metabolism / physiology; Gait / physiology; Humans; Male; Models, Theoretical; Muscle, Skeletal / physiology; Orthotic Devices; Tendons / physiology
TL;DR:
A musculoskeletal model of the human leg and a model of muscle energetics in simulations of muscle–tendon dynamics during hopping with and without elastic ankle exoskeletons showed that the total rate of metabolic energy consumption by ankle muscles was not significantly reduced by an ankleExoskeleton.

2013 journal article
Elastic ankle exoskeletons reduce soleus muscle force but not work in human hopping
JOURNAL OF APPLIED PHYSIOLOGY, 115(5), 579–585.
author keywords: ultrasound; fascicle; tendon; metabolic power; plantar flexors
MeSH headings : Adult; Ankle / physiology; Ankle Joint / physiology; Electromyography / methods; Energy Metabolism / physiology; Humans; Leg / physiopathology; Male; Muscle, Skeletal / physiology; Tendons / physiology; Walking / physiology
TL;DR:
The findings highlighted that parallel assistance to a muscle with appreciable series elasticity may have some negative consequences, and that the metabolic cost associated with generating force may be more pronounced than the cost of doing work for these muscles.

The mechanics and energetics of human walking and running: a joint level perspective
JOURNAL OF THE ROYAL SOCIETY INTERFACE, 9(66), 110–118.
author keywords: locomotion; speed; mechanical power; efficiency; cost of transport
MeSH headings : Adult; Ankle Joint / physiology; Biomechanical Phenomena; Calorimetry, Indirect; Energy Metabolism; Female; Gait; Hip Joint / physiology; Humans; Knee Joint / physiology; Male; Running; Walking
TL;DR:
Changing from walking to running resulted in a significant shift in power production from the hip to the ankle which may explain the higher efficiency of running at speeds above 2.0 m s−1 and shed light on a potential mechanism behind the walk–run transition.
