GMFCS III EXAMPLE
Look at the GMFM-66 data for this child. As you can see, the scores are gradually increasing as the child grows but does this report on how they are doing compared to their peers? Advance the slide to see the percentile comparison.
Here we see the same tabulated data with the percentile calculated and plotted on the right hand side.
If you look at the final GMFM score, it continues the steady increase seen previously. Adding the percentile data shows how this child is faring in comparison with children of similar age and degree of disability. This data shows a plateauing where the child is not maintaining the same rate of change from measurement point 3 to 4 as in the previous measurements. This does not negate the improvement made by this child but is a reminder of the value of the percentile scores.
In a similar fashion consider these results from a child classified as GMFCS V where there appears to be a steady decline in performance.
Revealing the percentile results shows that their peers would be losing performance at a faster rate so this child is really doing well.
