Dr. Stineman’s expertise is in statistical modeling, measurement and the development of patient classification systems. She applies mixed quantitative research and qualitative methods. She and her colleagues developed a patient classification approach that forms the basis for Medicare’s national payment system for inpatient rehabilitation, established staging systems for addressing patients’ mobility and abilities to care for themselves, established measures for addressing the effects of medical conditions on quality of life, and addressed the effect of environmental barriers on the expression of disability. Currently she and her colleagues are developing therapeutic tools for enhancing patient understanding of and involvement in the recovery process, and studying the effects of comprehensive rehabilitation services on patient outcomes following lower extremity amputation. The foundation for Dr. Stineman’s work is an expanded biopsycho-ecological model that views interactions between the person and environment as contributing to illness and disability. By this ecological framework medical interventions move beyond the person to include the environment in which he or she lives.
