The energy cost of split-belt walking for a variety of belt speed combinations

Julia K. Butterfield et al.

Summary: This study investigates the difference in energy costs between split-belt walking and tied-belt walking, and finds that split-belt walking is slightly more energy-consuming than tied-belt walking, with increased belt speed differences leading to increased energy costs. When designing clinical rehabilitation protocols, the potential therapeutic benefits and increased energy demands of higher belt speed differences need to be considered.

The split-belt rimless wheel

Julia K. Butterfield et al.

Summary: Split-belt treadmill walking can extract energy from the environment, and the split-belt rimless wheel model demonstrates how to take advantage of the treadmill. The study shows that the split-belt rimless wheel can steadily walk by capturing energy from the treadmill, adapting to various leg angles and belt speeds. The physical split-belt rimless wheel robot is also able to walk continuously. However, humans do not maximize the energy generated by the treadmill, possibly due to other aspects of walking that limit their ability to benefit from it.

Humans trade off whole-body energy cost to avoid overburdening muscles while walking

Kirsty A. McDonald et al.

Summary: This study found that humans are more inclined to avoid excessive muscle activation and fatigue during walking rather than minimizing energy expenditure. Muscle activation costs are more closely related to metabolic energy use, and people also minimize muscle activation when choosing walking patterns. This research provides empirical evidence of non-energetic optimization in human walking behavior.

Patterns of asymmetry and energy cost generated from predictive simulations of hemiparetic gait

Russell T. Johnson et al.

Summary: This article investigates the impact of hemiparesis on gait performance. Predictive musculoskeletal modeling method was used to analyze the effects of weak muscles on spatiotemporal asymmetry and metabolic cost, and it was found that spatiotemporal asymmetry may be more optimal for individuals with hemiparesis.

Using asymmetry to your advantage: learning to acquire and accept external assistance during prolonged split-belt walking

Natalia Sanchez et al.

Summary: The study shows that people naturally learn to step further forward on the fast belt of a split-belt treadmill to acquire positive mechanical work and reduce the work performed by their legs when given sufficient time to adapt. This process of acquiring positive work from the treadmill to reduce energetic cost requires longer exposure than traditionally allotted in adaptation studies. The findings support the idea that reducing energetic cost plays a central role in shaping adaptive locomotion and continues over more extended timescales than typically studied.

Perspective on musculoskeletal modelling and predictive simulations of human movement to assess the neuromechanics of gait

Friedl De Groote et al.

Summary: Understanding human locomotion is challenging due to the complex interactions between the central nervous system and the musculoskeletal system. Predictive simulations based on mathematical models of the neuro-musculoskeletal system can reveal principles of locomotion by elucidating cause-effect relationships. However, to gain new fundamental insight into motor control of gait, more detailed neuro-musculoskeletal models and simulation approaches that take uncertainty into account are required.

How adaptation, training, and customization contribute to benefits from exoskeleton assistance

Katherine L. Poggensee et al.

Summary: The study showed that moderate-variation training combined with customized assistance can greatly reduce energy cost when using exoskeletons, but training requires a longer time. Different types of training also have a significant impact on improving expertise, and users reduced mechanical power from the exoskeleton as they became more proficient.

Transtibial limb loss does not increase metabolic cost in three-dimensional computer simulations of human walking

Ross H. Miller et al.

Summary: Through computer modeling, it has been found that transtibial limb loss does not directly lead to an increase in metabolic cost of walking. Even when deviations from able-bodied walking mechanics are minimized, the metabolic cost remains the same.
