A Framework for Understanding UEMSD Theory,Research,and Management

Abstract

UEMSD's (Upper Extremity Musculoskeletal Disorders) are complex in terms of causation, identification, treatment and intervention. The users of musculoskeletal disorders research require a better understanding how their action and responsibilities fit into the context of UEMSD causation and intervention theory, research and management. This paper describes a framework to aid in understanding the scope and multi-factorial nature of UEMSD theory, research, and management. The purpose of the framework is to provide a context in which UEMSD's can be discussed. The framework proposes a cyclical loop, which represents an individual's responses during an event cycle. The framework is composed of three elements: Life's Activities, Modifiers, and Outcomes. Both the physical state and mental state of the individual are considered. The physical characteristics of activities and environments are filtered and/or amplified by the presence of individual predisposing or protective factors, resulting in the development health outcomes. The framework espouses a chain of events and effects which shows the potential complexity of the interactions between the factors, which may or may not result in a UEMSD. The framework is discussed in terms of the need for research to broaden the understanding of the role of specific factors in the development of UEMSDs.
