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 variability and fall risk in community-living older adults: a 1-year prospective study.
Archives of Physical Medicine and Rehabilitation, 2001OBJECTIVE To test the hypothesis that increased gait variability predicts falls among community-living older adults attending an outpatient clinic. DESIGN Prospective, cohort study. SETTING Three outpatient geriatric clinics. PARTICIPANTS Fifty-two

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

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.

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

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.

Acoustic Gaits: Gait Analysis With Footstep Sounds
IEEE Transactions on Biomedical Engineering, 2015We describe the acoustic gaits-the natural human gait quantitative characteristics derived from the sound of footsteps as the person walks normally. We introduce the acoustic gait profile, which is obtained from temporal signal analysis of sound of footsteps collected by microphones and illustrate some of the spatio-temporal gait parameters that can be

A synergetic theory of quadrupedal gaits and gait transitions
Journal of Theoretical Biology, 1990We present a theoretical analysis of the patterns of interlimb co-ordination in the gaits of quadrupedal locomotion. Introducing as collective variables a set of relative phases that describe the co-ordination patterns, we classify gaits by their symmetry properties, which can be expressed as invariances under groups of transformations.
