Every year workers' low-back, hand, and arm problems lead to time away from jobs and reduce the nation's economic productivity. The connection of these problems to workplace activities-from carrying boxes to lifting patients to pounding computer keyboards-is the subject of major disagreements among workers, employers, advocacy groups, and researchers. Musculoskeletal Disorders and the Workplace examines the scientific basis for connecting musculoskeletal disorders with the workplace, considering people, job tasks, and work environments. A multidisciplinary panel draws conclusions about the likelihood of causal links and the effectiveness of various intervention strategies. The panel also offers recommendations for what actions can be considered on the basis of current information and for closing information gaps. This book presents the latest information on the prevalence, incidence, and costs of musculoskeletal disorders and identifies factors that influence injury reporting. It reviews the broad scope of evidence: epidemiological studies of physical and psychosocial variables, basic biology, biomechanics, and physical and behavioral responses to stress. Given the magnitude of the problem-approximately 1 million people miss some work each year-and the current trends in workplace practices, this volume will be a must for advocates for workplace health, policy makers, employers, employees, medical professionals, engineers, lawyers, and labor officials.

Most routine motor tasks are complex, involving load transmission through out the body, intricate balance, and eye-head-shoulder-hand-torso-leg coor dination. The quest toward understanding how we perform such tasks with skill and grace, often in the presence of unpredictable perturbations, has a long history. This book arose from the Ninth Engineering Foundation Con ference on Biomechanics and Neural Control of Movement, held in Deer Creek, Ohio, in June 1996. This unique conference, which has met every 2 to 4 years since the late 1960s, is well known for its informal format that promotes high-level, up-to-date discussions on the key issues in the field. The intent is to capture the high quality ofthe knowledge and discourse that is an integral part of this conference series. The book is organized into ten sections. Section I provides a brief intro duction to the terminology and conceptual foundations of the field of move ment science; it is intended primarily for students. All but two of the re maining nine sections share a common format: (l) a designated section editor; (2) an introductory didactic chapter, solicited from recognized lead ers; and (3) three to six state-of-the-art perspective chapters. Some per spective chapters are followed by commentaries by selected experts that provide balance and insight. Section VI is the largest section, and it con sists of nine perspective chapters without commentaries.

This 5000-page masterwork is literally the last word on the topic and will be an essential resource for many. Unique in its breadth and detail, this encyclopedia offers a comprehensive and highly readable guide to a complex and fast-expanding field. The five-volume reference work gathers more than 10,000 entries, including in-depth essays by internationally known experts, and short keynotes explaining essential terms and phrases. In addition, expert editors contribute detailed introductory chapters to each of 43 topic fields ranging from the fundamentals of neuroscience to fascinating developments in the new, inter-disciplinary fields of Computational Neuroscience and Neurophilosophy. Some 1,000 multi-color illustrations enhance and expand the writings.

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.

This is the most comprehensive and up-to-date account of the control of vertebrate head movements and its biomechanical and neural basis. It covers the entire spectrum of research on head-neck movements, ranging from the global description and analysis of a particular behavior to its underlying mechanisms at the level of neurotransmitter release and membrane biophysics.

Advanced Analysis of Motor Development explores how research is conducted in testing major issues and questions in motor development. It also looks at the evolution of research in the field, its current status, and possible future directions. This text is one of the few to examine motor development models and theories analytically while providing a context for advanced students in motor development so they can understand current and classic research in the field. Traditionally, graduate study in motor development has been approached through a compilation of readings from various sources. This text meets the need for in-depth study in a more cohesive manner by presenting parallels and highlighting relationships among research studies that independent readings might not provide. In addition, Advanced Analysis of Motor Development builds a foundation in the theories and approaches in the field and demonstrates how they drive contemporary research in motor development. A valuable text for graduate students beginning their own research projects or making the transition from student to researcher, this text focuses on examining and interpreting research in the field. Respected researchers Haywood, Roberton, and Getchell explain the history and evolution of the field and articulate key research issues. As they examine each of the main models and theories that have influenced the field, they share how motor development research can be applied to the fields of physical education, special education, physical therapy, and rehabilitation sciences. With its emphasis on critical inquiry, Advanced Analysis of Motor Development will help students examine important topics and questions in the field in a more sophisticated manner. They will learn to analyze research methods and results as they deepen their understanding of developmental phenomena. For each category of movement skills covered (posture and balance, foot locomotion, ballistic skills, and manipulative skills), the authors first offer a survey of the pertinent research and then present an in-depth discussion of the landmark studies. In analyzing these studies, students will come to appreciate the detail of research and begin to explore possibilities for their own future research. Throughout the text, special elements help students focus on analysis. Tips for Novice Researchers sidebars highlight issues and questions raised by research and offer suggestions for further exploration and study. Comparative tables detail the differences in the purpose, methods, and results of key studies to help students understand not only what the studies found but also the relevance of those findings. With Advanced Analysis of Motor Development, readers will discover how research focusing on the major issues and central questions in motor development is produced and begin to conceptualize their own research. Readers will encounter the most important models and theories; dissect some of the seminal and recent articles that test these models and theories; and examine issues such as nature and nurture, discontinuity and continuity, and progression and regression. Advanced Analysis of Motor Development will guide students to a deeper understanding of research in life span motor development and enable them to examine how the complexities of motor development can be addressed in their respective professions.
