Summary
Human gait termination relies on ankle braking, with knee extension and step shortening enhancing control. Intermittent ankle braking leverages passive dynamics for stable transitions to standing.
Area of Science:
- Biomechanics
- Robotics
- Human Locomotion
Background:
- Human gait termination involves complex control strategies.
- Previous models lacked evaluation of individual strategy importance.
Purpose of the Study:
- To evaluate the relative importance of three control strategies for human gait termination.
- To develop a simplified bipedal locomotion model for analyzing gait termination.
Main Methods:
- Extended a bipedal spring-mass walking model with minimal parameters.
- Investigated three explicit control strategies: final step shortening, ankle braking, and knee extension.
- Analyzed the model's behavior under separate and combined strategy application.
Main Results:
- Ankle braking alone effectively reduced propulsive force for quiet standing.
- Combining strategies increased the parameter range for successful gait termination.
- Intermittent ankle control, utilizing passive dynamics, proved particularly effective.
- Model predictions align with experimental observations of human center of mass and leg forces.
Conclusions:
- Ankle braking is a crucial strategy for human gait termination.
- Combined strategies and intermittent control enhance gait termination capabilities.
- The simplified model provides a foundation for understanding human gait control mechanisms.

01:44Termination of Translation
27.9K
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

3.5K
An interesting force in everyday life is the force of drag on an object when it is moving in a fluid. Like friction, the drag force always opposes the motion of an object. Unlike simple friction, the drag force is proportional to some function of the velocity of the object in that fluid. This functionality is complicated and depends upon the shape of the object, its size, its velocity, and the fluid it is in. For most large objects, such as cyclists, cars, and baseballs, that are not moving too...

A simple pendulum consists of a small diameter ball suspended from a string, which has negligible mass but is strong enough to not stretch. In our daily life, pendulums have many uses, such as in clocks, on a swing set, and on a sinker on a fishing line.
The period of a simple pendulum depends on two factors: its length and the acceleration due to gravity. The period is completely independent of any other factors, such as mass or maximum displacement. For small displacements, a pendulum is...

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.
