Book Description
This book presents new findings on body image and also introduces new neuroscience-based methods for the fields of neurology and neurorehabilitation. Even when the hand is stationary we know its position – information that is needed by the brain to plan movements. If the sensory input from a limb is removed as the result of an accident, or as part of an experiment with local anesthesia, then a ‘phantom’ limb commonly develops. We used ischemic anesthesia of one limb to study the mechanisms that define this phenomenon. Surprisingly, if the fingers, wrist, elbow, ankle, and knee are extended before and during an ischemic block, then the perceived limb is flexed at the joint and vice versa. Furthermore, the limb is perceived to move continuously with no default position. The key parameter for these illusory changes in limb position is the difference in discharge rates between afferents in the flexor and extensor muscles at a joint. The final position of the phantom limb depends on its initial position, suggesting that a body image uses incoming proprioceptive information for determination of starting points and endpoints when generating movements. In addition, the change in position does not involve limb postures that are anatomically impossible, suggesting that illusory posture is constrained by body maps. These results provide new information about how the brain generates phantom limbs.

Book Description
Neuroscientist V.S. Ramachandran is internationally renowned for uncovering answers to the deep and quirky questions of human nature that few scientists have dared to address. His bold insights about the brain are matched only by the stunning simplicity of his experiments -- using such low-tech tools as cotton swabs, glasses of water and dime-store mirrors. In Phantoms in the Brain, Dr. Ramachandran recounts how his work with patients who have bizarre neurological disorders has shed new light on the deep architecture of the brain, and what these findings tell us about who we are, how we construct our body image, why we laugh or become depressed, why we may believe in God, how we make decisions, deceive ourselves and dream, perhaps even why we're so clever at philosophy, music and art. Some of his most notable cases: A woman paralyzed on the left side of her body who believes she is lifting a tray of drinks with both hands offers a unique opportunity to test Freud's theory of denial. A man who insists he is talking with God challenges us to ask: Could we be "wired" for religious experience? A woman who hallucinates cartoon characters illustrates how, in a sense, we are all hallucinating, all the time. Dr. Ramachandran's inspired medical detective work pushes the boundaries of medicine's last great frontier -- the human mind -- yielding new and provocative insights into the "big questions" about consciousness and the self.

Book Description
The U.S. Census Bureau has reported that 56.7 million Americans had some type of disability in 2010, which represents 18.7 percent of the civilian noninstitutionalized population included in the 2010 Survey of Income and Program Participation. The U.S. Social Security Administration (SSA) provides disability benefits through the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. As of December 2015, approximately 11 million individuals were SSDI beneficiaries, and about 8 million were SSI beneficiaries. SSA currently considers assistive devices in the nonmedical and medical areas of its program guidelines. During determinations of substantial gainful activity and income eligibility for SSI benefits, the reasonable cost of items, devices, or services applicants need to enable them to work with their impairment is subtracted from eligible earnings, even if those items or services are used for activities of daily living in addition to work. In addition, SSA considers assistive devices in its medical disability determination process and assessment of work capacity. The Promise of Assistive Technology to Enhance Activity and Work Participation provides an analysis of selected assistive products and technologies, including wheeled and seated mobility devices, upper-extremity prostheses, and products and technologies selected by the committee that pertain to hearing and to communication and speech in adults.

Book Description
This book explores the fascinating area of interpersonal coordination in force production tasks, outlining the author’s extensive research to date and presenting stimulating new perspectives. The purpose is to provide a detailed exposition of current understanding of the science behind interpersonal joint action. Readers will find clear explanation of concepts from social cognition and neuroscience that are key to an understanding of the field, including the social brain hypothesis, the mirror neuron system, and joint action, as well as other relevant background information. The author then proceeds to present an overview of recent original studies on interpersonal movement coordination performed at his laboratory in Japan. These studies provide insights into such issues as complementary and synchronous force production in joint action, bidirectional transfer between joint and solo actions, and motor control hierarchy in joint action involving bimanual force. They also set the direction for integration of knowledge of physical properties and social cognition. The book will be of interest for researchers and graduate students in all areas of the biomedical sciences.

Book Description
Each year in the United States, an estimated 40,000 persons lose a limb. Of these amputees, approximately 30% lose a hand or an arm. This loss is most frequently related to trauma occurring in the healthy young adult male and is often work related. Approximately 3% of all amputees are born with congenital limb absence. In children, the ratio of congenital to acquired amputation is 2: 1, and the ratio of upper-limb to lower-limb amputees is 1. 2: 1. Therefore, since relatively few amputations result in upper-limb loss, only a small number of health practitioners, even those specializing in amputee rehabilitation, have the opportunity to provide services for a significant number of arm amputees. As a result, clinicians need to share their experiences so that the full range of options for optimum care and rehabilitation of the patient population may be considered. To meet this challenge for wider communication of clinical experience, a group of upper-limb amputee specialists met in Houston, Texas, in 1981 to serve as the core faculty for a course entitled "Contemporary Issues in Upper Extremity Amputation and Prosthetic Function. " This program provided the opportunity for surgeons, physiatrists, engineers, prosthetists, social workers, psychologists, occupational therapists, and physical therapists from the United States and Canada to discuss their extensive experience in working with upper extremity amputees. A second conference continuing the discussion of upper limb amputee rehabilitation was held one year later.

Book Description
Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States. The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function. In the context of the growing opioid problem, the U.S. Food and Drug Administration (FDA) launched an Opioids Action Plan in early 2016. As part of this plan, the FDA asked the National Academies of Sciences, Engineering, and Medicine to convene a committee to update the state of the science on pain research, care, and education and to identify actions the FDA and others can take to respond to the opioid epidemic, with a particular focus on informing FDA's development of a formal method for incorporating individual and societal considerations into its risk-benefit framework for opioid approval and monitoring.
