Functional Stretching Exercise Submitted for Spastic Diplegic Children: A Randomized Control Study

Table 5

Statistical power and minimal clinical difference for both groups.

Variables	Statistical power (%)		Minimal clinical difference
	Control group	Study group	Control group	Study group
H∖M ratio	83*	98*	0.02	0.015
Popliteal angle	80*	86.9*	2.5	2.7
Stride length	83*	94*	3.2	1.8
Stride speed	80*	86*	0.04	0.012
Stance phase	87*	93*	1.5	0.5

∗Statistical power ≥ 80% has large effect.
