Values for rhythm perception and production scores for each group at each time point are presented as means with ranges in parentheses, with ICC, SEM, and MDC values also provided
NT, neurotypical; ICC, intra-class correlation; SEM, standard error of measurement; MDC, minimal detectable change; %, percent; ms, millisecond
^aAverage of 3 time points
^bICC calculated based on time points 1 and 2
