20.500.12556/RUP-21591 Reliability of postural sway measures during single-leg stance a analysis using conventional and complementary error metrics 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. reliability center of pressure balance assessment measurement error force platform ponovljivost center pritiska ocena ravnotežja merilna napaka tenziometrijska plošča true false false Angleški jezik Slovenski jezik Neznano 2025-08-23 23:32:33 2025-08-23 23:32:34 2025-08-26 03:03:07 0000-00-00 00:00:00 2025 0 0 str. 1-7 2025 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2025-01-01 796.2 1825-1234 10.1007/s11332-025-01527-2 246425603 https://link.springer.com/article/10.1007/s11332-025-01527-2 1 bda1d99c-8068-11f0-8f0b-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=31384 https://doi.org/10.1007/s11332-025-01527-2 1 bed4007d-8068-11f0-8f0b-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=31385 RAZ_Kozinc_Ziga_2025.pdf RAZ_Kozinc_Ziga_2025.pdf 1 CF470136ED9BB013D854E73CB5F2001F aff1f8d90733b1089d9cfb64ee5c4f065a311f380f800a02847c9668bea62654 f7517971-8068-11f0-8f0b-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=31386 Fakulteta za vede o zdravju 0 0 0
