The Grasping Hand

Anatomical guide leverages exceptional dissection images to elucidate the biomechanics of the hand and upper extremity The hand is a unique instrument that executes the commands of the brain and expresses the nuances of the mind. The Grasping Hand: Structural and Functional Anatomy of the Hand and Upper Extremity by Amit Gupta and Makoto Tamai is a state-of-the-art book that details the functions of the hand to feel, receive, gather, collect and hold, as well as the complex role that the whole upper extremity plays in enabling these actions. The anatomical structures intrinsic to these functions are detailed through illuminating cadaveric dissections and succinct text. Organized in 5 sections and 38 chapters, the book begins with a chapter detailing the intriguing history of hand anatomy, followed by a section encompassing the structural and functional fundamentals. The third section covers general anatomy and function, with discussions of the nerves and vascularity of the upper extremity, as well as the brachial plexus. The fourth section features 26 anatomically organized chapters from the shoulder to the fingertip with anatomical and functional insights on the joints, fascia and retinacula, interosseus membrane, tendons and more. The single chapter comprising the final section covers imaging and anatomy. Key Highlights Pioneers in modern hand surgery share vast collective knowledge and pearls on hand and upper extremity anatomy and biomechanics Over 1,100 exquisite, original dissections of lightly embalmed fresh cadaveric arms provide unique visual insights about underlying tissues and structures High quality, never before published original photographs enhance understanding of anatomy, physiology, and pathology This practical resource is ideal for reviewing anatomy and biomechanics prior to performing hand, wrist, arm, elbow, and shoulder surgery, making it essential reading for orthopaedic surgeons, fellows, and hand specialists. This book is also useful for students of human anatomy, physical and occupational therapists, medical students, and anyone interested in upper extremity anatomy and function.

The simple task of grasping objects has been studied for centuries by scientists, therapists and engineers who have tried to understand and duplicate the versatility of the human hand. Using an interdisciplinary approach and new framework for looking at prehension, the authors uncover the subleties of the amazing interaction between the hand and the brain. They draw from such diverse fields as experimental psychology, kinesiology, robotics, neural networks, artificial intelligence, neuropsychology and rehabilitation. A triangle strategy is presented, starting from conceptual models that suggest both experimental and computational models. Chapters describe the multiple postures established by the hand, phases in the dynamic process of reaching for, grasping and manipulating various objects, and the constraints acting on such activity. Appendices provide the complete anatomy of the upper limb, the basics of computational modelling, and the fundamentals of prosthetic and dextrous robot hands. The ultimate goal of this book is to develop a common vocabularly for multidisciplinary researchers who strive to understand a system as complex as the hand under the control of the human brain.

In 2005, the Supreme Court ruled that the city of New London, Connecticut, could condemn fifteen residential properties in order to transfer them to a new private owner. Although the Fifth Amendment only permits the taking of private property for “public use,” the Court ruled that the transfer of condemned land to private parties for “economic development” is permitted by the Constitution—even if the government cannot prove that the expected development will ever actually happen. The Court’s decision in Kelo v. City of New London empowered the grasping hand of the state at the expense of the invisible hand of the market. In this detailed study of one of the most controversial Supreme Court cases in modern times, Ilya Somin argues that Kelo was a grave error. Economic development and “blight” condemnations are unconstitutional under both originalist and most “living constitution” theories of legal interpretation. They also victimize the poor and the politically weak for the benefit of powerful interest groups and often destroy more economic value than they create. Kelo itself exemplifies these patterns. The residents targeted for condemnation lacked the influence needed to combat the formidable government and corporate interests arrayed against them. Moreover, the city’s poorly conceived development plan ultimately failed: the condemned land lies empty to this day, occupied only by feral cats. The Supreme Court’s unpopular ruling triggered an unprecedented political reaction, with forty-five states passing new laws intended to limit the use of eminent domain. But many of the new laws impose few or no genuine constraints on takings. The Kelo backlash led to significant progress, but not nearly as much as it may have seemed. Despite its outcome, the closely divided 5-4 ruling shattered what many believed to be a consensus that virtually any condemnation qualifies as a public use under the Fifth Amendment. It also showed that there is widespread public opposition to eminent domain abuse. With controversy over takings sure to continue, The Grasping Hand offers the first book-length analysis of Kelo by a legal scholar, alongside a broader history of the dispute over public use and eminent domain and an evaluation of options for reform.

Used for gestures of communication, environmental exploration, and the grasping and manipulating of objects, the hand has a vital role in our lives. The hand's anatomical structure and neural control are among the most complex and detailed of human motor systems. Hand and Brain is a comprehensive overview of the hand's sensorimotor control. It discusses mediating variables in perception and prehension, the coordination of muscles with the central nervous system, the nature of movement control and hand positioning, hand-arm coordination in reaching and grasping, and the sensory function of the hand. In the last decade the rapid growth of neuroscience has been paralleled by a surge of interest in hand function. This reflects the fact that many of the fundamental issues facing neuroscientists today--including the problem of relating physiology to behavior--are central to the study of sensorimotor control of the hand. This book takes a broad interdisciplinary perspective on the control of hand movements that includes neurophysiology, neuroanatomy, psychology and neuropsychology, and biomechanics. The authors, who have all made significant scientific contributions in their own right, have sought to introduce their chosen topics in a manner that the undergraduate reader will be able to follow without sacrificing detailed and up-to-date coverage ofthe major developments. Uses an interdisciplinary approach including behavioral and neurophysiological data Describes a variety of experimental methodologies Treats neural computations necessary for the control of movement Covers implications of biomechanics for control, sensory mechanisms, and perceptual processing (haptics) Includes manipulative hand function as well as reaching Overviews each group of chapters using link sections Contains an integrated index and a glosssary The five sections cover: Mediating variables in perception and prehension The coordination of muscles with the central nervous system The nature of movement control and hand positioning Hand-arm coordination in reaching and grasping The sensory function of the hand

This is a cornerstone publication in robotic grasping. The authors have developed an internationally recognized expertise in this area. Additionally, they designed and built several prototypes which attracted the attention of the scientific community. The purpose of this book is to summarize years of research and to present, in an attractive format, the expertise developed by the authors on a new technology for grasping which has achieved great success both in theory and in practice.

Provides guidelines for examining the hand of a patient in relation to grasp and classifying the grasp pattern. The book provides pictorial illustrations of the structure of the hand and the developmental stages of grasping, then describes 12 pencil grasps used for handwriting and 23 grasps used to perform occupational tasks involved in daily living. The descriptions are accompanied by black and white photographs. Annotation copyrighted by Book News, Inc., Portland, OR

"A startling argument . . . provocative . . . absorbing." --The Boston Globe "Ambitious . . . arresting . . . celebrates the importance of hands to our lives today as well as to the history of our species." --The New York Times Book Review The human hand is a miracle of biomechanics, one of the most remarkable adaptations in the history of evolution. The hands of a concert pianist can elicit glorious sound and stir emotion; those of a surgeon can perform the most delicate operations; those of a rock climber allow him to scale a vertical mountain wall. Neurologist Frank R. Wilson makes the striking claim that it is because of the unique structure of the hand and its evolution in cooperation with the brain that Homo sapiens became the most intelligent, preeminent animal on the earth. In this fascinating book, Wilson moves from a discussion of the hand's evolution--and how its intimate communication with the brain affects such areas as neurology, psychology, and linguistics--to provocative new ideas about human creativity and how best to nurture it. Like Oliver Sacks and Stephen Jay Gould, Wilson handles a daunting range of scientific knowledge with a surprising deftness and a profound curiosity about human possibility. Provocative, illuminating, and delightful to read, The Hand encourages us to think in new ways about one of our most taken-for-granted assets. "A mark of the book's excellence [is that] it makes the reader aware of the wonder in trivial, everyday acts, and reveals the complexity behind the simplest manipulation." --The Washington Post

Surveying normal hand function in health individuals, this book presents a conceptual framework for analysing what is known about it. It organises human-hand research on a continuum that ranges from activities that are sensory to those with a strong motor component. It is useful for researchers in neuroscience, cognitive science, and gerontology.
