Abstract des Autors
The purpose of this study was to assess the reliability of quadriceps muscle stiffness assessment in individuals with Osgood-Schlatter disease (OSD). Ten subjects were tested for four trials on two occasions within a 2-week period on a Kin-Com dynamometer. A regression coefficient was derived from force-angle data to determine stiffness. Intertrial and interday intraclass correlations (ICC) and standard error of measurement (SEM) were derived from a repeated-measures ANOVA. Between-trial assessments were more reliable for the outer range 65 to 100ø knee flexion (ICC = .95 & .81) than the inner range 35 to 65ø knee flexion (ICC = .72 & .57) for both sessions. The average SEMs for outer and inner ranges (over 35ø) were 1.1 and 1.3 N, respectively. Assessments between days were less reliable, which may reflect the weekly variation in the presentation of athletes with OSD. It remains unclear if the SEM lies within the limits of clinical significance. Verf.-Referat
