Validity of the new Backache Index (BAI) in patients with low back pain

Andre Farasyn MSc and Romain Meeusen PhD

The aim of this study was to explore the reliability, validity, and responsiveness of the new Backache Index in patients with LBP.  Patients with LBP filled in disability questionnaires; pain rating scales and physical impairment tests were completed in function of construct validity and correlation studies. A subgroup was evaluated for interobserver and test-retest reliability, and a second group was reassessed after two active treatment sessions to verify the responsiveness compared with other examined variables.  The validity of the BAI was explored through a correlation with the standard Oswestry LBP Disability Index (ODI), the McGill LBP Questionnaire Index (MPQ), and the Visual Analogue Scale (VAS).  The authors conclude that the BAI appears to be a reliable and valid assessment of overall restricted spinal movements in case of LBP and discriminates between successful and unsuccessful treatment outcome.
