Objective: researching of stabilometric parameters of primary school children, doing complex coordination types of sport and having the features of undifferentiated connective tissue dysplasia (UCTD). Materials and methods: 36 children at the age from 7 to 11 years engaged in gymnastics and sports aerobics were examined. All athletes were divided into two groups, taking into account the presence or absence of UCTD signs based on results of a screening algorithm «Outward signs score of systemic involvement of connective tissue in children». Postural function assessment was carried out by the standard method (intermediate foot position) on the «Force plate ST-150».
Results: athletes with UCTD were worse than their healthy peers across the majority of stabilometric indicators (p<0.05). Indicators in both groups were higher than the physiological age norm. Statistically significant differences were found among such UCTD grounds as the dolichostenomelia and arachnodactyly. In the group of healthy children postural stability is provided mostly by the proprioceptive system, and in children with UCTD the leading system is the visual system.
Conclusions: athlets with dysplasia with dolichostenomelia and arachnodactyly need special (rehabilitation) activites on stabiloplatform with biofeedback for improving postural stability in the course of training process.
