Responsiveness of Turkish Disability Questionnaires in Chronic Non-Specific Low Back Pain
Sponsor: Acibadem University
Summary
This prospective observational clinimetric study aimed to compare the responsiveness of the Turkish versions of the Roland-Morris Disability Questionnaire (RMDQ), Oswestry Disability Index (ODI), and Quebec Back Pain Disability Scale (QBPDS) in adults with chronic non-specific low back pain. The study also aimed to estimate minimal important change (MIC) values for these instruments using a Global Perceived Effect (GPE) scale as an external anchor and to interpret the MIC estimates in relation to measurement error.

Interventions
Standardized Physiotherapy Program
Participants received a standardized physiotherapy program reflecting routine clinical practice, consisting of 16 supervised sessions delivered over four weeks (four sessions per week; approximately 60 minutes per session). The program included lumbar stabilization exercises, trunk strengthening, lower-limb flexibility training, and postural education. Adjunctive electrotherapy was applied when clinically indicated and included superficial heat, conventional transcutaneous electrical nerve stimulation (TENS), and therapeutic ultrasound. All sessions were delivered by licensed physiotherapists according to a standardized treatment protocol. The physiotherapy program served as a change-inducing clinical context for the clinimetric evaluation rather than as an intervention for comparative efficacy testing.
