2. Reliability of postural sway measures during single-leg stance : a analysis using conventional and complementary error metricsŽiga Kozinc, Aurora Kuliqi, Iza Obal, 2025, izvirni znanstveni članek Opis: This study examined the test–retest reliability of postural sway measures during single-leg stance in healthy adults. Forty-eight participants performed three 30-s barefoot trials across two sessions separated by 3–5 days, using a force platform to derive eight center of pressure (CoP) variables. Reliability was assessed using conventional reliability metrics (intraclass correlation coefficient (ICC), typical error (TE), coefficient of variation (CV), and minimal detectable change (MDC)), as well as recently suggested complementary indices (mean absolute error (MAE) and mean absolute percentage error (MAPE)). Most CoP-derived variables showed good relative reliability, with ICCs ranging from 0.71 to 0.86. Sway velocity and frequency-based measures were the most consistent (e.g., sway velocity AP: ICC = 0.85), while sway area showed higher variability (ICC = 0.71, MAPE = 20.1%). Systematic improvements were observed between sessions, particularly for sway velocity (all p < 0.001) and area (p = 0.002). Absolute error metrics such as MAE and MAPE provided additional insight into individual-level variability, often exceeding values indicated by CV. The findings support the use of single-leg CoP measures in research and clinical assessments but highlight the need for careful interpretation of reliability based on both relative and absolute indices.
