The minimally clinically important difference (MCID) is an important concept for
interpreting the results of clinical research. This paper proposes a rationale
for defining an MCID for the Gait Profile Score (GPS) based on an analysis of the
difference in median GPS for children classified at different levels of the
Functional Assessment Questionnaire. A strong linear correlation between median
score and FAQ level was found. An MCID of 1.6 degrees is therefore suggested,
reflecting the mean difference between adjacent FAQ levels. Comparison of this
value with (i) the standard deviation of GPS from typically developing children
(1.4 degrees ) and (ii) the percentage of the difference between the median GPS
for each FAQ level and that for typically developing children offers further
support to suggest that 1.6 degrees is an appropriate figure.
