20.500.12556/RUL-184192 Intra- and interrater reliability of the Modified Ashworth Scale and its association with the Tardieu Scale in children with cerebral palsy Background The Modified Ashworth Scale is a widely used tool for assessing spasticity. The aim of this study was to evaluate the intra- and interrater reliability of the Modified Ashworth Scale and its association with the Tardieu Scale in children with cerebral palsy. Methods In this cross-sectional study, 23 children with cerebral palsy were included. The intra- and interrater reliability of the Modified Ashworth Scale was assessed for the elbow, knee, and plantar flexors of the foot. The results of the Tardieu Scale were included to evaluate the association between the two scales. The intraclass correlation coefficient (ICC) was used to assess reliability, and Spearman’s correlation coefficient was used to assess the association between the Modified Ashworth Scale and the Tardieu Scale. All muscles assessed were included in the analysis, regardless of the anatomical classification of physical impairment. Results Intrarater reliability (ICC) in our sample was excellent for all muscles assessed (ICC = 0.91–0.99). Interrater reliability was generally good, with confidence intervals indicating moderate to good reliability in certain muscle groups (ICC = 0.80–0.89). A moderate positive correlation was observed between the Tardieu Scale and the Modified Ashworth Scale for all muscles assessed. Conclusions The results demonstrated excellent intrarater and generally good interrater reliability in a heterogeneous primary healthcare sample, with a moderate positive correlation between the scales studied. However, caution is warranted when interpreting findings at the individual level. children cerebral palsy spasticity assessment psychometric properties modified Ashworth scale Tardieu scale true false true Angleški jezik Ni določen Članek v reviji 2026-07-01 11:44:01 2026-07-01 11:44:02 2026-07-03 03:30:05 0000-00-00 00:00:00 2026 0 0 14 str. art. e21349 Vol. 14 2026 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 2026-01-01 616.831-053.2 2167-8359 10.7717/peerj.21349 283222019 peerj-21349.pdf peerj-21349.pdf 1 0D292AAA32DFDCA3380EC218A8BC4DD6 6f36a803ae0b6ef5ab6cf8ab31060faed1c45a1d8f1adcd6cc1f4eaea34feab5 9a78ce94-7531-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=236782 https://peerj.com/articles/21349/ 1 498e64d1-7531-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=236780 Zdravstvena fakulteta Medicinska fakulteta 0 0 0
