TL;DR: This text encompasses the work of Dr Jacquelin Perry in her years as a therapist and surgeon focusing on the human gait, suitable for incorporating into many athletic training programmes, university physical therapy programmes and gait workshops.
Abstract: 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. In addition to the descriptions of the gait functions, a representative group of clinical examples has been included to facilitate the interpretation of the identified gait deviations. The book includes detailed laboratory records with illustrations and photographs. Intended as a reference for health care professionals involved in musculoskeletal patient care, the text is suitable for incorporating into many athletic training programmes, university physical therapy programmes and gait workshops.

TL;DR: The dynamics are most clearly demonstrated by a machine powered only by gravity, but they can be combined easily with active energy input to produce efficient and dextrous walking over a broad range of terrain.
Abstract: There exists a class of two-legged machines for which walking is a natural dynamic mode. Once started on a shallow slope, a machine of this class will settle into a steady gait quite comparable to ...

TL;DR: The gait analysis laboratory provides quantified assessments of human locomotion which assist in the orthopaedic management of various pediatric gait pathologies by utilizing a video-based data collection strategy similar to commercially available systems for motion data collection.
Abstract: The clinical objective of the gait analysis laboratory, developed by United Technologies Corporation (Hartford, CT, USA) in 1980, at the Newington Children's Hospital is to provide quantified assessments of human locomotion which assist in the orthopaedic management of various pediatric gait pathologies. The motion measurement system utilizes a video-based data collection strategy similar to commercially available systems for motion data collection. Anatomically aligned, passive, retroreflective markers placed on the subject are illuminated, detected, and stored in dedicated camera hardware while data are acquired from force platforms and EMG transducers. Three-dimensional marker position information is used to determine: (i) the orientation of segmentally-embedded coordinate systems, (ii) instantaneous joint center locations, and (iii) joint angles. Joint kinetics, i.e., moments and powers, may also be computed if valid force plate data are collected.

TL;DR: Gait speed can be expected to be reduced in individuals of greater age and of lesser height and lower extremity muscle strength and normative values should give clinicians a reference against which patient performance can be compared in a variety of settings.
Abstract: Objectives: to establish reference values for both comfortable and maximum gait speed and to describe the reliability of the gait speed measures and the correlation of selected variables with them. Design: descriptive and cross-sectional. Methods: subjects were 230 healthy volunteers. Gait was timed over a 7.62 m expanse of floor. Actual and height normalized speed were determined. Lower extremity muscle strength was measured with a hand-held dynamometer. Results: mean comfortable gait speed ranged from 127.2 cm/s for women in their seventies to 146.2 cm/s for men in their forties. Mean maximum gait speed ranged from 174.9 cm/s for women in their seventies to 253-3 cm/s for men in their twenties. Both gait speed measures were reliable (coefficients > 0.903) and correlated significantly with age (r^ — 0.210), height (r^ 0.220) and the strengths of four measured lower extremity muscle actions (r = 0.190-0.500). The muscle action strengths most strongly correlated with gait speed were nondominant hip abduction (comfortable speed) and knee extension (maximum speed). Conclusions: these normative values should give clinicians a reference against which patient performance can be compared in a variety of settings. Gait speed can be expected to be reduced in individuals of greater age and of lesser height and lower extremity muscle strength.

TL;DR: This work presents three robots based on passive-dynamics, with small active power sources substituted for gravity, which can walk on level ground and use less control and less energy than other powered robots, yet walk more naturally, further suggesting the importance of passive-Dynamics in human locomotion.
Abstract: Passive-dynamic walkers are simple mechanical devices, composed of solid parts connected by joints, that walk stably down a slope. They have no motors or controllers, yet can have remarkably humanlike motions. This suggests that these machines are useful models of human locomotion; however, they cannot walk on level ground. Here we present three robots based on passive-dynamics, with small active power sources substituted for gravity, which can walk on level ground. These robots use less control and less energy than other powered robots, yet walk more naturally, further suggesting the importance of passive-dynamics in human locomotion.
