20.500.12556/RUL-176923 Repeatibility and reliability of knee joint rotational laxity measurements with double goniometry Ponovljivost i pouzdanost mjerenja opuštanja koljenskog zgloba u rotaciji dvostrukom goniometrijom The results of existing studies on the range of motion in the knee joint rotation are contradictory. The best method for measuring knee rotation has not yet been found. The purpose of this study was to investigate the repeatability and reliability of knee joint rotational laxity measurement using two magnetic goniometers. Thirty healthy subjects (15 males and 15 females) aged between 20 and 32 years participated in the study. Internal and external rotation of the left and right knee joints were measured with double goniometry in the sitting position with 90° flexion of the knee. There was no statistically significant difference in measurements between first and second session. The intraclass correlation coefficient (ICC) for repeatability ranged from 0.812 to 0.858 and for reliability from 0.655 to 0.837. Within-subject coefficient of variation was less than 10%, standard error of measurement was between 1.4o and 2.0o , minimal detectable change was between 2.5o and 3.8o . The measured values of internal and external rotation did not completely agree with those reported by other authors. The ICC values indicated good to very good repeatability and reliability of the double goniometry measurement of rotational knee laxity. Technical improvements will be required before translation into clinical practice. Rezultati dosadašnjih studija opsega pokreta u rotaciji koljenskog zgloba su proturječni. Dosad nije utvrđeno koja je najbolja metoda mjerenja rotacije koljena. Namjera ove studije bila je ispitati ponovljivost i pouzdanost mjerenja opuštanja koljenskog zgloba u rotaciji pomoću dva magnetska goniometra. U ispitivanju je sudjelovalo 30 zdravih osoba (15 muškaraca i 15 žena) u dobi od 20 do 32 godine. Dvostrukom goniometrijom mjerena je unutarnja i vanjska rotacija lijevog i desnog koljenskog zgloba u sjedećem položaju uz fleksiju koljena od 90°. Nije bilo statistički značajne razlike između prvog i drugog mjerenja. Intraklasni koeficijent korelacije (ICC) za ponovljivost kretao se od 0,812 do 0,858, a za pouzdanost od 0,655 do 0,837. Koeficijent varijacije za pojedinog ispitanika bio je manji od 10%, standardna greška mjerenja iznosila je od 1,4° do 2,0°, a najmanja promjena koju je bilo moguće otkriti iznosila je od 2,5° do 3,8°. Izmjerene vrijednosti unutarnje i vanjske rotacije nisu se u potpunosti slagale s onima drugih autora. Vrijednosti ICC ukazuju na dobru do vrlo dobru ponovljivost i pouzdanost mjerenja opuštanja koljena u rotaciji dvostrukom goniometrijom. Prije uvođenja u kliničku praksu bit će potrebna daljnja tehnička poboljšanja. rotational laxity knee joint double goniometry range of motion true false true Angleški jezik Hrvaški jezik Članek v reviji 2025-12-15 12:24:44 2025-12-15 12:24:46 2025-12-26 03:49:10 0000-00-00 00:00:00 2025 0 0 Str. 271-279 no. 2 Vol. 64 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-01-01 615.8 1333-9451 10.20471/acc.2025.64.02.11 261421059 vol64_2_11_ACC_albanese_084_(1).pdf vol64_2_11_ACC_albanese_084_(1).pdf 1 37395F030B1F35539D887114580A6032 bdac2653d2b8cadf1859fc3017d7700c71861caece8aa19c2e71114ff6d9f6f1 b05ae5f6-d9a8-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=223736 https://hrcak.srce.hr/clanak/488027 1 43e3f5f4-d9a8-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=223735 Zdravstvena fakulteta 0 0 0
