Sensitivity of foot intrusion kinematics during walking on granular media
نویسندگان
چکیده
Many legged organisms and robots must contend with walking across granular media (GM), substrates whose properties depend on compaction and disturbance history. Movement over GM can be particularly challenging because the ground may yield to an intruder, displaying both solid and fluid-like behavior [1]. This yielding behavior can lead to the locomotor performance of an animal or device being highly sensitive to its foot kinematics.

Comparative Studies Reveal Principles of Movement on and within Granular Media
Terrestrial locomotion can take place on complex substrates such as leaf litter, debris, and soil that flow or solidify in response to stress. While principles of movement in air and water are revealed through study of the hydrodynamic equations of fluid motion, discovery of principles of movement in complex terrestrial environments is less advanced in part because describing the physics of lim...
متن کاملEffect of Fatigue on Knee Kinematics and Kinetics During Walking in Individuals With Flat Feet
Purpose: Flat feet associates with altered knee kinematics, kinetics, as well as knee pain. Fatigue of plantar intrinsic foot muscles may increase the navicular drop. However, it is unclear how fatigue influences the knee pain in individuals with flat feet. The purpose of this study was to assess the effect of fatigue on knee kinematics and kinetics in flat feet people during walking. Methods:...
متن کاملAge-related changes in foot kinematics during walking
Background Differences in dynamic foot function between young and older adults have been reported [1], however foot kinematics during walking remain largely unquantified. Our understanding of foot kinematics during walking is largely based on single-segment foot models, which limits the inferences that can be made about foot motion. This study aimed to determine if differences in foot kinematic...

Objective Stroke occurs when the supply of blood to the brain is either interrupted or reduced. The clinical presentation varies from minor neurological symptoms to severe deficits, depending on the location and the size of the brain lesion. Hemiparesis is one of the most striking features in the acute phase. Many other deficits may also be present, including postural imbalance. All persistent ...
متن کاملEvaluation of a Viscoelastic Ankle-Foot Prosthesis at Slow and Normal Walking Speeds on an Able-Bodied Subject
Objectives: This paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. The objective was to control the ankle hysteresis at slow and normal walking speeds. Methods: Inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for...
