These findings are the first analyzing in depth the responsiveness of the Mini-BESTest and are in line with those concerning the BBS. Moreover, Romero et al39 recently underscored that measurement error (and parameters derived from it) often are not constant across different levels of function and related scores. As a consequence, caution is mandatory when interpreting and using these MIC values in different populations and settings, particularly considering the intrinsic weaknesses of GRC.21,42 The GRC (and the MIC values derived from it) suffers from the problem of the subjective retrospective judgments of change (eg, due to “recall bias,” or problematic patient ability to understand the context of improvement).21 To reduce these drawbacks, we used the mean of 2 ratings (participant and therapist), after reporting the correlations between them.
