.The MDC95 value was 3.5 points for the Mini-BESTest and 6.2 points for the BBS. In the only study that had sufficient data to calculate the MDC for the Mini-BESTest,19 this value was about 4 (ie, very close to our result). Romero et al39 recently found an MDC95 value of 6.5 points for the BBS and noted that this value was not constant across different levels of function, being lower in individuals with better performance. Our findings also appear to be confirmed by the observation that reported MDC90–95 values for the BBS range from 5 to 8 points.36,39–41
