Ergonomics and Prevention of Disability Due to Musculoskeletal Disorders: A State-of-the-Science Symposium

Abstract

This symposium is concerned with rehabilitation, ergonomics and preventing work disability. Specifically it is concerned with determining the state of the science and identifying research opportunities that could result in major reductions in work disability. Disability has be defined as (Brandt and Pope 1997): Disability is defined as a limitation in performing certain roles and tasks that society expects of an individual It is the expression of the gap between a person's capabilities and the demands of the environment - the interaction of person's limitations with social and physical environmental factors. Available data show that there are many persons in our society who are disabled in that they are unable to achieve expectations established by employers, e.g., production rates, quantities and quality, without endangering themselves or others in the workplace or community. This expectation typically extends to forty hours per week, but could be more or less hours. Limitations in performance may result from conditions of birth, illness or injury. They also may be a primary or secondary effect of work. This is the case with Work Related Musculoskeletal Disorders; WMSDs. WMSDs are a leading cause of work disability and compensation in many contemporary work settings. Although this program focuses on prevention of disability due to WMSDs, it is broadly concerned with the prevention of all disability. The models and methods discussed have common elements that are applicable to many if not all persons and situations. For example, the above definition defines disability as a “gap” between job demands and worker capacities. This definition applies to a person with paraplegia as well as a person with carpal tunnel syndrome. In both instances, methods are needed for assessing and comparing worker capacities and job demands. The program includes presentations by leading investigators who will draw on their own work and work of others to describe the state of the art and develop recommendations for future research.
