Multiple comparisons between the intervention cycles with relation to the outcomes after rectus femoris transfer surgery in children with stiff knee gait

Variables	Intervention cycle: pre- and postoperative measures
	Preoperative versus short-term			Preoperative versus long-term			Short-term versus long-term
	Mean	SE	p value	Mean	SE	p value	Mean	SE	p value
PKF	7.33	1.37	< 0.001	1.71	1.43	0.7	−5.62	1.16	< 0.001
KROM	2.36	1.67	0.483	−2.08	1.58	0.57	−4.43	1.48	0.01
TiPKF	−1	0.006	0.19	−2	0.007	0.04	−1	0.005	0.53
VKF	76.55	13.6	< 0.001	28.55	11.78	0.05	−48	10.73	< 0.001

PKF = peak knee flexion in degrees; KROM = knee ROM in degrees; TiPKF = time to peak knee flexion in percent of the gait cycle; VKF = knee flexion velocity in degrees/second; the significance level is 0.01.
