Abstract
OBJECTIVE
This study examines the test-retest reliability, the minimal clinically important difference (MCID), and its correlation with the Rolland Morris Disability Questionnaire (RMDQ) of the Dubousset Functional Test (DFT) in evaluating the functional capacity and dynamic balance of patients with chronic non-specific low back pain (cnsLBP).
METHODS
Seventy-five patients with cnsLBP aged 18 years and over were included. The Five-Repetition Sit-To-Stand Test (5R-STS), the subcomponents of the DFT (the Up and Walk Test, the Steps Test, the Down and Sitting Test, and the Dual-Tasking Test) were administered to the patients. Patients were rested for 1 h, and the DFT was applied again. Pain level was evaluated with the Visual Analogue Scale before the tests started and after the tests were completed. Self-report function assessment was made using the RMDQ.
RESULTS
The test-retest reliability of the subcomponents of the DFT was excellent. The ICCs were: 0.91, 0.86, 0.89, and 0.89, respectively. The standard measurement errors of the subcomponents of the DFT were 0.32, 0.12, 0.14, and 0.25, respectively. The subcomponents of the DFT were highly correlated with the RMDQ and 5R-STS with the correlation coefficients of 0,83, 0,83, 0,79, 0,83 and 0,81, 0,75, 0,73, and 0,82, respectively (p < 0.01). The MCIDs of the subcomponents were 0,60, 0,23, 0,27, and 0,48, respectively.
CONCLUSION
The DFT is reliable in evaluating patients' functional capacity and dynamic balance with cnsLBP without causing discomfort. It is simple, quick, and simultaneously assesses multiple areas contributing to spinal alignment, muscle integrity, and balance.
