Our activities of daily living inherently involve interacting with the physical environment. This interaction involves both reactive (feedback) and proactive (feedforward) gait adaptations. Reactive adaptations involve responses to mechanical perturbations and occur, for instance, when we stumble over a doorstep or slip on an icy spot on the pavement ...

Beyond the classic clinical description, recent studies have quantitatively evaluated gait and balance dysfunction in cerebellar ataxias by means of modern motion analysis systems. These systems have the aim of clearly and quantitatively describing the differences, with respect to healthy subjects, in kinematic, kinetic, and surface electromyography ...

This text encompasses the work of Dr Jacquelin Perry in her years as a therapist and surgeon focusing on the human gait. The text is broken down into four sections: fundamentals; normal gait; pathological gait; and gait analysis systems.

The methodology of gait analysis and gaits of monkeys
American Journal of Physical Anthropology, 1965AbstractMotion pictures were taken of two subadult monkeys (Macaca and Lagothrix) running and walking on level ground. The film strips were analyzed to determine the timing of the limb contacts with the surface. Generalizations and associations from the film analysis were used to construct a model system which categorizes gait types for quadrupedal ...

This chapter discusses the anatomic basis related to control of head and trunk posture, and symptom and syndromes caused by its impairment. The spinal cord contains machinery for stepping, the locomotor generator. However, the spinal cord is under the control of supraspinal centers. In human walking, intention or attention takes part to various degrees,

Journal of Experimental Psychology: Human Perception and Performance, 1983
Our ability of perceive the identity and naturalness of a human gait is examined in a series of four experiments involving computer-animated stick figures. The results indicate that the perceived naturalness of a walking or running gait can be influenced by the motion of any limb segment, but the perceived identity of these gaits is primarily ...

Gait style and gait content: bilinear models for gait recognition using gait re-sampling
Sixth IEEE International Conference on Automatic Face and Gesture Recognition, 2004. Proceedings., 2004Human identification using gait is a challenging computer vision task due to the dynamic motion of gait and the existence of various sources of variations such as viewpoint, walking surface, clothing, etc. In this paper we propose a gait recognition algorithm based on bilinear decomposition of gait data into time-invariant gait-style and time-dependent

Cognitive decline and neurodegenerative disease have been implicated in gait dysfunction via disturbance of top-down control mechanisms. Gait velocity decreases, variability increases, and ability to multitask while walking is impaired as cognition declines.

Walking is an extraordinarily complex task requiring integration of the entire nervous system, making gait susceptible to a variety of underlying neurologic abnormalities. Gait disorders are particularly prevalent in the elderly and increase fall risk. In this review we discuss an approach to the examination of gait and highlight key features of common

Gaits and gait transitions for legged robots
Proceedings 2006 IEEE International Conference on Robotics and Automation, 2006. ICRA 2006., 2006This paper introduces the concept of gait transitions, acyclic feedforward motion patterns that allow a robot to switch from one gait to another. Legged robots often utilize collections of gait patterns to locomote over a variety of surfaces. Each feedforward gait is generally tuned for a specific surface and set of operating conditions.
