However, these instruments may not fully reflect patients' actual physical performance. The Back Performance Scale (BPS-TR) may provide a more objective, performance-based approach to evaluating functional limitations. This study aimed to investigate the psychometric properties of the BPS-TR in patients with AS.MethodsA total of 107 patients with AS were included. Functional performance was assessed using five standardized tasks: sock, pick-up, roll-up, fingertip-to-floor, and lifting tests. Convergent validity was examined using BASFI, BASDAI, ASQoL, and BASMI. Test-retest reliability was evaluated in 40 patients after a one-week interval using the intraclass correlation coefficient [ICC_2,1].ResultsThe BPS-TR demonstrated excellent test-retest reliability [ICC_2,1 = 0.890] and acceptable internal consistency (Cronbach's α = 0.787). Measurement error was small (SEM = 0.53; MDC₉₅ = 1.47). Significant moderate correlations were found with BASFI (r = 0.654), ASQoL (r = 0.590), BASDAI (r = 0.615), and BASMI (r = 0.630) (all p < 0.001). Exploratory factor analysis supported a unidimensional structure explaining 62.4% of the total variance.ConclusionsThe BPS-TR is a valid, reliable, and practical performance-based scale for assessing functional limitations in patients with AS.

Peak vertical ground reaction force from three valid force-plate strikes per limb was normalized to body weight, and an asymmetry index (AI) was calculated. AI ≥ 0.10 was used as a pragmatic exploratory threshold for asymmetric loading. Candidate radiologic variables included Cobb angle, lumbar lordosis, thoracic kyphosis, apical vertebral rotation, apical vertebral translation, coronal balance, sagittal balance, pelvic torsion, and pelvic obliquity. Sensitivity analyses included alternative AI thresholds, ridge regression, and walking-speed-adjusted models.ResultsOverall, 132/180 participants (73.3%) were asymmetric. Pelvic obliquity was positively associated with asymmetric loading classification, and this association was directionally consistent across AI cut-offs of 0.08, 0.10, and 0.12.
