**5. Conclusions**

The improvement of the selected spatio-temporal and kinematic gait parameters, when using AFO, is also reflected in the results of GDI and GVI. These gait indices, being the single, numerical parameter, reflecting changes in gait pattern after various therapeutical interventions, would be also valuable in the clinical practice in the group of spastic hemiplegic CP children.
