The methods of the three- dimensional gait evaluation enable the objective evaluation of the gait in children with cerebral palsy. One of the indexes used to the analysis is Gillette Gait Index ( GGI); it consists of 16 clinically meaningful kinematic and three-dimensional parameters.The study was conducted with use of the three-dimensional system of gait analysis, carried by the team of pediatric neurologists, physiotherapists and engineers. The analyzed group consisted of eight CP patients treated with botulin toxin intensively rehabilitated after the botulin treatment. The data were compared to ten CP patients put on rehabilitation without the botulin treatment.

The patients treated with botulin were evaluated three times: before the botulin administration, then three and then six months after it. In the other group the evaluation was conducted three months after rehabilitation start. The results of gait evaluation were compared to the gait pattern of the healthy children; the normal values were worked out by the authors.

We observed the increase of the gait speed and frequency of steps after the botulin treatment and rehabilitation; the GGI decreased both after three and six months of observation.

We do treat the results presented above as the pilot-study; the evaluation of the larger groups of children with cerebral palsy is conducted. The objective method of CP children gait evaluation may be the helpful tool for clinicians to optimize the way of CP children treatment.
