Work Related Musculoskeletal Disorders

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.

Estimated costs associated with lost days and compensation claims related to musculoskeletal disorders-including back pains and repetitive motion injuries-range from $13 billion to $20 billion annually. This is a serious national problem that has spurred considerable debate about the causal links between such disorders and risk factors in the workplace. This book presents a preliminary assessment of what is known about the relationship between musculoskeletal disorders and what may cause them. It includes papers and a workshop summary of findings from orthopedic surgery, public health, occupational medicine, epidemiology, risk analysis, ergonomics, and human factors. Topics covered include the biological responses of tissues to stress, the biomechanics of work stressors, the epidemiology of physical work factors, and the contributions of individual, recreational, and social factors to such disorders. The book also considers the relative success of various workplace interventions for prevention and rehabilitation.

Work-related musculoskeletal disorders (WRMSDs) refer to a wide range of inflammatory and degenerative conditions that occur in the workplace or are caused by work activities. WRMSDs affect the muscles, tendons, ligaments, joints, peripheral nerves, and supporting blood vessels. These conditions can cause pain and functional impairment and they often result in direct economic costs to both the workplace and the worker. Injuries sustained at work can negatively affect a person's physical and mental health as well as a company's bottom line. This book describes the human musculoskeletal system, including such topics as anthropometry and posture, as it relates to accidents and injuries in the workplace. Chapters discuss such subjects as job standards; risk assessment; direct and indirect costs of WRMSDs; epidemiology, etiology, and pathology of WRMSDs; engineering and administrative controls; risk factor identification; injury management; and education and training. It presents a holistic approach to identifying, intervening, and preventing WRMSDs.

Work related muskuloskeletal disorders, or WMSDs, have become a major problem in many industrialised countries. It was previously thought that the number of repetitive jobs would decline in the future, leading to a decline in the number of WMSDs: however, this has not been the case. Some government agencies expect WMSDs to be one of the major work-related disorders into the new Millenium. This book contains evaluated scientific information that will help prevent WMSDs, derived from original research and field experience via a Canadian Government sponsored project on work related musculoskeletal disorders. The expert group's goal was twofold: the first objective was to examine the work relatedness of WMSDs in the light of existing literature, and the second was to explore and synthesize information, avenues and approaches that could help in the prevention of WMSDS.

A collection of lectures from renowned international experts from the 1999 International Course for the Advanced Training in Occupational Health. Deals with work-related musculoskeletal disorders.

The Social Security Administration (SSA) administers two programs that provide disability benefits: the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. SSDI provides disability benefits to people (under the full retirement age) who are no longer able to work because of a disabling medical condition. SSI provides income assistance for disabled, blind, and aged people who have limited income and resources regardless of their prior participation in the labor force. Both programs share a common disability determination process administered by SSA and state agencies as well as a common definition of disability for adults: "the inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months." Disabled workers might receive either SSDI benefits or SSI payments, or both, depending on their recent work history and current income and assets. Disabled workers might also receive benefits from other public programs such as workers' compensation, which insures against work-related illness or injuries occurring on the job, but those other programs have their own definitions and eligibility criteria. Selected Health Conditions and Likelihood of Improvement with Treatment identifies and defines the professionally accepted, standard measurements of outcomes improvement for medical conditions. This report also identifies specific, long-lasting medical conditions for adults in the categories of mental health disorders, cancers, and musculoskeletal disorders. Specifically, these conditions are disabling for a length of time, but typically don't result in permanently disabling limitations; are responsive to treatment; and after a specific length of time of treatment, improve to the point at which the conditions are no longer disabling.

In May 1998 the National Institutes of Health asked the National Academy of Sciences/National Research Council to assemble a group of experts to examine the scientific literature relevant to work-related musculoskeletal disorders of the lower back, neck, and upper extremities. A steering committee was convened to design a workshop, to identify leading researchers on the topic to participate, and to prepare a report based on the workshop discussions and their own expertise. In addition, the steering committee was asked to address, to the extent possible, a set of seven questions posed by Congressman Robert Livingston on the topic of work-related musculoskeletal disorders. The steering committee includes experts in orthopedic surgery, occupational medicine, epidemiology, ergonomics, human factors, statistics, and risk analysis. This document is based on the evidence presented and discussed at the two-day Workshop on Work-Related Musculoskeletal Injuries: Examining the Research Base, which was held on August 21 and 22, 1998, and on follow-up deliberations of the steering committee, reflecting its own expertise.

Whether you call them work-related upper limb disorders (WRULDs), cumulative trauma disorders (CTDS), or occupational overuse syndromes (OOSs), these conditions are a cause of pain, disability and suffering to workers worldwide. These designations often imply that their causes are related to work, but the supporting evidence can be unclear. Transparency is important, especially when it is necessary to form a connection with work factors to obtain treatment or compensation. This book addresses the dilemma. Written by a professional ergonomist with almost 40 years of experience in workplace ergonomics, this book combines a critical summary and assessment of the epidemiological literature with an exploration of the scientific and medical evidence for possible causal mechanisms to develop well-informed conclusions on causation of a number of common musculoskeletal disorders of the upper limb and intervertebral disc injury. Although much of the book focuses on physical factors, the role of psychosocial factors is increasingly being recognized and an additional chapter reviews a number of the current theories relating to this important issue. Features Focuses on a clear and authoritative account of the evidence for the role of work in the causation of commonly occurring ULDs and disc injury Provides an up-to-date compilation of the scientific evidence, devoid of views based on assumptions or prejudice Presents a clear explanation of the most likely causal mechanisms for common ULDs and disc injuries Includes a summary of theories concerning the role played by psychosocial factors Outlines the statistical evidence in a clear and understandable manner Bridges the gap between the evidence-base in the scientific and medical research literature and the practitioner
