Table 2.

Comparison of FMS score before and after lengthening in the two groups of patients, showing statistically significant improvement in 5 m ambulation in patients treated by lengthening and deformity correction

	FMS score for 5 m before vs. after lengthening	FMS score for 50 m before vs. after lengthening	FMS score for 500 m before vs. after lengthening
Lengthening only group (n = 21)
Z	−0.577	−0.749	0.000
Significance	0.564 (not significant)	0.454 (not significant)	Not significant
Lengthening and deformity correction group (n = 11)
Z	−2.070	−0.816	0.000
Significance	0.038 (significant)	0.414 (not significant)	1.000 (not significant)

There was no statistically significant difference in the lengthening only group and with regard to the 50 and 500 m ambulation scores in the lengthening and deformity correction group.
