This study aims to compare the validity and reliability of core stability and functional capacity measurements when performed face-to-face and through tele-assessment in individuals with chronic low back pain. Chronic low back pain affects a large portion of the adult population and is associated with reduced core muscle endurance, impaired postural control, and decreased functional capacity. Tele-assessment has become increasingly important, especially after the pandemic, but there is limited evidence regarding its validity and reliability for physical performance tests. In this study, 36 individuals with nonspecific chronic low back pain will complete core stability tests (plank, side plank, Biering-Sørensen test, and trunk flexor endurance test), functional capacity tests (Timed Up and Go, 30-Second Chair Stand, and 1-Minute Stair Climb), and questionnaires including the Visual Analog Scale and the Oswestry Disability Index. Assessments will be performed by the same physiotherapist first face-to-face in the clinic, then by tele-assessment, and tele-assessment will be repeated after 5-7 days to assess test-retest reliability. The results are expected to show whether tele-assessment provides accurate and reliable measurements compared with traditional face-to-face evaluation. The findings may support the safe and evidence-based use of tele-assessment methods in physiotherapy practice for individuals with chronic low back pain.
