Table 7

Median and range of preoperative Functional Mobility Scale (FMS) ratings and at postoperative follow-ups 1 and 2 and results of statistical analyses. The Friedman analyses indicate overall difference between the 3 time points; follow-up tests with the Wilcoxon signed-ranks test indicate differences between pairs of time points.

FMS scores	Pre-op median (range)	Follow-up 1 median (range)	Follow-up 2 median (range)	Friedman test (N = 17)	Wilcoxon pre-op to follow-up 1 (N = 17)	Wilcoxon follow-up 1 to follow-up 2 (N = 17)	Wilcoxon pre-op to follow-up 2 (N = 17)
FMS 5 meters (home)	2 (1–5)	4 (2–6)	5 (1–6)
FMS 50 meters (school)	2 (1–5)	2 (2–5)	3 (1–6)
FMS 500 (shopping center)	1 (1–5)	2 (1–5)	3 (1–6)

Functional Mobility Scale: 1 = wheelchair; 2 = walker/frame; 3 = crutches without help; 4 = canes without help; 5 = independent level surfaces; and 6 = independent all surfaces.
