To present a framework for future analyses of back pain recurrence and explore the applicability and relevance of existing recurrence indicators.
Empirical studies of back pain have included a variety of indicators of recurrence, resulting in a range of findings about recurrence rates and associated factors. Little is known about the relationships between existing indicators.
Literature overview, expert panel, and workshop discussion at the IX International Forum on Primary Care Research on Low Back Pain.
Using the International Classification of Functioning, Disability, and Health (ICF), disabling back pain was conceptualized as a health condition, i.e., back pain disorder (BPD), and BPD recurrence was conceptualized as involving a return of atypical back pain and/or back-pain-related difficulty performing tasks and actions related to the initial episode. Using the ICF, 2 types of recurrence indicators were identified: those directly describing components of BPD and those indirectly doing so (e.g., recurrence of health care utilization).
In light of the difficulty in measuring BPD recurrence, transparent definitions and a clear understanding of the implications of using particular indicators is required. Future research should focus: on examining the capture BPD recurrence by various research instruments, improving understanding of the relationship between indicators, and gaining insight into how individuals experiencing BPD view recurrence.
Disabling back pain was conceptualized as a health condition–back pain disorder (BPD). This allowed focusing on aspects of individuals' experience: impairment, activity limitations, and participation restrictions. Recurrence of BPD was defined as any postinitial episode. Two types of recurrence indicators were identified: describing components of BPD directly and indirectly.
