[Comparison of Characteristics between Different Turning Strategies]
Summary
Turning gait involves changes in walking characteristics like reduced speed and increased stance time compared to straight walking. Inside leg turning offers better control, while outside leg turning provides more stability.
Area of Science:
- Biomechanics
- Human Locomotion
- Robotics
Background:
- Turning gait is a fundamental human movement, yet its biomechanics are less understood than straight walking.
- Limited research exists on the distinct gait characteristics and strategies employed during turning maneuvers.
Purpose of the Study:
- To investigate the differences in gait and plantar pressure parameters between straight and turning gaits.
- To compare the biomechanical effects of two turning strategies: inside leg turning and outside leg turning.
- To provide data for the development of bipedal robots and assistive walking devices.
Main Methods:
- Simultaneous measurement of gait and plantar pressure parameters using Vicon motion capture and a plantar pressure system.
- Analysis of data from 10 healthy young men performing straight walking and 90° turns with two distinct strategies.
Main Results:
- Turning gait exhibited reduced stride velocity and increased stride time and stance time proportion compared to straight walking.
- Inside leg turning required greater muscle control for propulsion, whereas outside leg turning enhanced stability.
- Significant differences in gait parameters were observed between the two turning strategies.
Conclusions:
- Turning gait significantly alters biomechanical parameters compared to straight walking.
- The choice of turning strategy impacts stability and muscle control requirements.
- Findings offer valuable data for robotic gait design and rehabilitation strategies.

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

When a force is applied parallel to the top surface of a solid, it resists the applied force due to the internal frictional forces between the layers of the solid known as shearing resistance. However, when the force is removed, the shearing forces restore the original shape of the solid. Other deformation forces also cause temporary changes in shape if the forces are not beyond a threshold magnitude. Solids tend to retain their shape, making the study of their rest and motion easier. Beyond...

Fluids differ from solids primarily in their molecular structure and stress response. Solids have tightly packed molecules with strong intermolecular forces, maintaining their shape and resisting deformation. In contrast, fluids have molecules spaced farther apart with weaker forces, allowing them to flow and deform easily.
Fluids, which include both liquids and gases, are substances that deform continuously under shearing stress. For example, water and oil are liquids with molecules that can...

The Bipolar Junction Transistor (BJT), specifically in a common-emitter configuration, exhibits distinct current-voltage characteristics crucial for understanding its behavior in electronic circuits. These characteristics are established through experimental measurements of voltage and current relationships.
For input characteristics, the base-emitter voltage is varied, maintaining a constant collector-emitter voltage. This setup reveals a Shockley-type dependence of the collector current on...

Junction Field Effect Transistors (JFETs) exhibit specific operational characteristics based on the relationship between the drain current (id) and the drain-source voltage (Vds), along with varying gate-source voltages (Vgs).
The core of a JFET's operation is controlling drain current by modulating the gate-source voltage. When the drain and gate voltage are set to zero, the JFET exhibits no net current flow, representing a state of equilibrium. The drain current increases linearly as the...
