Absolute and relative intrarater reliability of the modified motor assessment scale according to Uppsala academic hospital-99

• Background For some of the most commonly used motor measures, psychometric properties, and minimal detectable change (MDC95) remain largely unknown, limiting the interpretability of tests. Objective The aim was to establish intrarater reliability, MDC95 and floor- and ceiling effects for a modified version of the Motor Assessment Scale (M-MAS UAS-99). Methods Data was derived from an intervention study that enrolled 41 individuals with chronic stroke. Test scores from two subsequent assessments with 3 weeks apart were used for establishing the floor and ceiling effect, the intraclass correlation coefficient (ICC[2,1]), standard error mean (SEM) and the MDC95 for the total score, and subdomains of the M-MAS UAS-99. Results The intrarater reliability was excellent with an ICC[2,1] between 0.970 and 0.995 for both total score and subdomains. The MDC95 for the M-MAS UAS-99 total score was 1.22 which means >= 2.0 points on an individual basis. For bed mobility subdomain, a ceiling effect was seen, but not for the total score of the test. No floor effect was seen for the test. Conclusion M-MAS UAS-99 has excellent intrarater reliability. Any individual increase in test scores must reach 2.0 to be considered a true change.
