Ergonomics diagnosis components in rehabilitation: statistical evaluation of an assessment instrument

Abstract

The current paper examines an assessment instrument used for combined medical and occupational rehabilitation (MOR) in a group of German hospitals. Patients with a history of musculo-skeletal disease make up a significant proportion of those undergoing rehabilitation. Scale and factor structures, discriminant factors and clustering procedures used in the Bavaria rehabilitation patient assessment method (BRPAM) are investigated in a cross-sectional study involving a sample of 800 patients. Although the results reveal good correlation between differences in the job demand/patient capability profiles and the typical stresses to which the relevant occupation is exposed, analyses also indicate that several factors and items are unstable. According to subjective assessment by the patients, the therapeutic objectives are fully attained in some 80% of cases. Discrepancies between job demands and patient capability revealed by the BRPAM yield pointers to choice of therapy and its chances of success, but these need to be examined in greater detail in long-term studies.
