Biomechanics and Gait Analysis presents a comprehensive book on biomechanics that focuses on gait analysis. It is written primarily for biomedical engineering students, professionals and biomechanists with a strong emphasis on medical devices and assistive technology, but is also of interest to clinicians and physiologists. It allows novice readers to acquire the basics of gait analysis, while also helping expert readers update their knowledge. The book covers the most up-to-date acquisition and computational methods and advances in the field. Key topics include muscle mechanics and modeling, motor control and coordination, and measurements and assessments. This is the go to resource for an understanding of fundamental concepts and how to collect, analyze and interpret data for research, industry, clinical and sport. Details the fundamental issues leading to the biomechanical analyses of gait and posture Covers the theoretical basis and practical aspects associated with gait analysis Presents methods and tools used in the field, including electromyography, signal processing and spectral analysis, amongst others

The picture on the front cover of this book depicts a young man pulling a fishnet, a task of practical relevance for many centuries. It is a complex task, involving load transmission throughout the body, intricate balance, and eye head-hand coordination. The quest toward understanding how we perform such tasks with skill and grace, often in the presence of unpredictable pertur bations, has a long history. However, despite a history of magnificent sculptures and drawings of the human body which vividly depict muscle ac tivity and interaction, until more recent times our state of knowledge of human movement was rather primitive. During the past century this has changed; we now have developed a considerable database regarding the com position and basic properties of muscle and nerve tissue and the basic causal relations between neural function and biomechanical movement. Over the last few decades we have also seen an increased appreciation of the impor tance of musculoskeletal biomechanics: the neuromotor system must control movement within a world governed by mechanical laws. We have now col lected quantitative data for a wealth of human movements. Our capacity to understand the data we collect has been enhanced by our continually evolving modeling capabilities and by the availability of computational power. What have we learned? This book is designed to help synthesize our current knowledge regarding the role of muscles in human movement. The study of human movement is not a mature discipline.

A large number of volumes have been produced summarizing the work on generation and control of rhythmic movements, in particular locomotion. Unfortunately most of them focus on locomotor studies done on animals. This edited volume redresses that imbalance by focusing completely on human locomotor behaviour. The very nature of the problem has both necessitated and attracted researchers from a wide variety of disciplines ranging from psychology, neurophysiology, kinesiology, engineering, medicine to computer science. The different and unique perspectives they bring to this problem provide a comprehensive picture of the current state of knowledge on the generation and regulation of human locomotor behaviour. A common unifying theme of this volume is studying the adaptability of human gait to obtain insights into the control of locomotion. The intentional focus on "adaptability" is meant to draw attention to the importance of understanding the generation and regulation of "skilled locomotor behaviour" rather than just the generation of basic locomotor patterns which has been the major focus of animal studies. The synthesis chapter at the end of the volume examines how the questions posed, the technology, and the experimental and theoretical paradigms have evolved over the years, and what the future has in store for this important research domain.

Gait Analysis Laboratory is a comprehensive, interactive package for the study of human gait. It includes a text, IBM-compatible software, and an accompanying software manual. Everyone from undergraduate students to research professionals should find it easy to study over 250 variables involved in human gait with this package. And, this resource provides a study of gait in three dimensions instead of two. The book and software make the theory and tools of gait analysis available to anyone with a basic knowledge of mechanics and anatomy and with access to a personal computer, including researchers in biomechanics, kinesiology, biomedical engineering, and the movement sciences in general; students and teachers in physical education and physical therapy; and clinicians in orthopaedic surgery, physical therapy, podiatry, rehabilitation, neurology, and sports medicine. Dynamics of Human Gait text: the text - a theoretical introduction to human gait - contains five chapters. Chapter One explains the walking human as a series of interconnected systems that form the framework for detailed gait analysis. Chapter Two emphasizes the three-dimensional and cyclic nature of human gait.Chapter Three integrates anthropometric, kinematic, and force-plate data to form a 3D analysis of gait. Chapter Four describes the basics of electromyography. And Chapter Five contains a case study of the gait patterns of a person with a movement disability. GaitLab software: the GaitLab software contains three separate programs - Gaitmath, Gaitplot, and Animate - that help users apply the theoretical information in the text. Gaitmath allows users to input data to calculate five sets of parameters for gait - body segment parameters, linear kinematics, centres of gravity, angular kinematics, and dynamics of joints. Gaitplot plots these parameters graphically in many combinations. It also includes an animation program that models data from Gaitmath into a simple moving figure. Researchers and students can input the sample data provided - or, with the necessary gait analysis hardware, they can capture their own data and use the Gaitplot and Gaitmath programs to bring their data to life. The Animate program illustrates the gait patterns. Users can view colour-coded sequences of a nondisabled man walking on a treadmill.They can see how muscle activity, joint moments, and ground reaction forces are integrated. A freeze-frame function allows users to stop and look at any phase of the gait cycle. The accompanying software manual gives users all the information they need to run the software successfully. Hardware compatibility: the Gaitmath and Gaitplot programs can be run on any IBM or IBM-compatible personal computer equipped with a hard disk drive and a CGA monitor or a monochrome monitor with a graphics adapter. The Animate program requires an EGA or VGA card and monitor. This package should help everyone from student to professional understand the complexities of human gait.
