Content Comparison of Low Back Pain-Specific Measures Based on the International Classification of Functioning, Disability and Health (ICF)

Abstract

Comparison based on the ICF provides insight into both the breadth of health dimensions measured as well as the thoroughness and depth of measurement. Therefore, it can be a useful tool when selecting specific measures for a study. Compared with other types of qualitative review, the most important advantage of the content comparison of measures based on the ICF is the use of an external and independent reference to which all the instruments can be linked and by which all the instruments can be compared. The three back-specific measures are comparable, with their common focus on physical aspects of body functions and activities and participation.
