The reliability of the Modified Rivermead Mobility Index (MRMI) has not
previously been investigated in the very early post-stroke phase. The aim of the
study was to evaluate inter-rater and intra-rater reliability and internal
consistency in patients, 1-14 d post-stroke. METHOD: A cohort study with repeated
measures within 24 h, on 37 patients, 1-14 d post-stroke was conducted.
Inter-rater (two raters) and intra-rater (one rater) reliability was analyzed
using weighted kappa (kappa) statistics and internal consistency with Cronbach's
alpha and intra-class correlation (ICC), 3.k. RESULTS: Inter-rater and
intra-rater reliability was excellent (ICC coefficient 0.97 and 0.99) for MRMI
summary score. Intra-rater exact agreement for separate items was between 77% and
97%; kappa between 0.81 and 0.96. Inter-rater exact agreement for separate items
was between 68% and 92%; kappa 0.59-0.87. The internal consistency was high
(alpha 0.96; ICC 3.k 0.99). CONCLUSION: The MRMI is a reliable measure of
physical mobility in the early post-stroke phase.
