Responsiveness of a Patient Specific Outcome Measure Compared With the Oswestry Disability Index v2.1 and Roland and Morris Disability Questionnaire for Patients With Subacute and Chronic Low Back Pain

Abstract

The PSAQ was highly responsive to change in patients who report improvement in back symptoms but unlike the ODI and RMDQ was unable to detect deterioration. Overall, the ODI was more responsive than either the PSAQ or the RMDQ.
