The purpose of the investigation was to use hand-held dynamometry to compare a single trial versus maximal or mean values of muscular strength in individuals with mental retardation. Twenty-three subjects classified as moderately mentally retarded (12 male, 11 female) performed three trials on six muscle groups. The magnitudes of the first, maximal, and mean isometric force across muscle groups were compared using a repeated measures analysis of variance and the Greenhouse-Geiser adjustment for the critical level of significance. Data analysis revealed a significant main muscle group effect and measurement score effect, but no significant differences between a single trial and mean of three trials. However, there was a significant difference between the first or mean scores and maximal scores. Intraclass correlation coefficients demonstrated consistency across muscle groups. Findings support the use of a single trial or mean of three trials to document muscular strength in individuals with mental retardation. [ABSTRACT FROM AUTHOR] |
