[Kinesthetic characteristics of vertical stability in patients with infantile cerebral palsy].
The study aimed at analyzing, a speed of body center of gravity (BCG) displacement and a frequency of its vibrations in sagittal and frontal planes in healthy adolescents and children as well as patients with spastic diplegia hemiparetic, hyperkinetic and atonic-astatic forms of infantile cerebral palsy (ICP) using a platform of computer stabilography in Romberg position. The results obtained suggest the presence of kinesthetic peculiarities of BCG vibration parameters, characteristic of CCP patients and pathognomic for a certain disease type that can be used for differential diagnosis. A low level of the visual control for BCG displacement speed is a common feature for all CCP types. On the other hand, an analysis of spectral characteristics implies an important role of the visual analyzer in the control of BCG vibration frequency. Also a common feature is higher frequency spectrum power in sagittal plane, comparing to frontal one that takes place in healthy persons as well. Individual differences in the vertical postural maintenance were observed. In spastic diplegia and hemiparetic types, speed of BCG displacement is lower than in controls, and special characteristics of its oscillations are similar to those of healthy individuals. In hyperkinetic and atonic-astatic CCP types, speeds of BCG displacement and oscillation spectrum power are very high, being more pronounced in the former one.
