- None of the five clinical tests established significant diagnostic accuracy in patients with chronic low back pain.
BACKGROUND & OBJECTIVE
Low back spine instability has a prevalence of up to 57% in chronic low back pain (LBP) (1) and can be a significant cause of pain and disability (2), as well as recurrence (2,3).
The primary objective of this cross-sectional diagnostic study was to evaluate the accuracy of several lumbar instability exams whose diagnostic accuracy has not been evaluated or has not yet been conclusively determined. A secondary goal was to examine the diagnostic accuracy of a combination of specific historical and demographic variables with clinical instability exams to predict lumbar instability.
The diagnosis of lumbar segmental instability is challenging due to the lack of a proper gold standard.
- A cross-sectional diagnostic study following standards for reporting of diagnostic accuracy (STARD) guidelines.
