Weight and height rates and ranges of motion in preschoolers with consequences of hip joint dysplasia
Abstract
Purpose: to study the impact of hip joint dysplasia on individual parameters of preschoolers’ physical development and range of motion. Material and methods: The studу was conducted at the nursery schools. 40 children of 5–6 years old with the effects of the hip joints dysplasia fixed in medical documentation took part in this study. Research methods: theoretical analysis and generalization of literary sources; medical cards analysis; anthropometry (weight, height measurements); goniometry; mathematical statistics methods. Results: Both boys and girls of 5–6 years old, who had the consequences of hip dysplasia, showed slight downward deviations from the average normative rates of body weight. The similar deviations were recorded in growth rates in girls of 5–6 years. The values of the amplitude of flexion on the affected limb were significantly lower than on the healthy limb, on average, by 8.05±5.91° (6.9±5.06 %), extension – by 3.35±2.63° (17.65±11.68 %), abduction – by 9.05±6.59° (19.02±12.24 %), and internal rotation – by 6.1±2.81° (11.72±8.81 %). These data indicated a decrease in muscle tone of the affected limb, weakness of the joints and ligamentous apparatus and a decrease in the range of motion in the hip joint. The decrease in the amplitude of the internal rotation of the affected limb took place on the background of valgus deformation of the knee and ankle joints. Conclusions: The effect of hip dysplasia on the indicators of physical development manifested in slight downward deviations from the normative indicators of bodyweight and growth of the examined children. A comparative analysis of the range of motion in the hip joint indicated the presence of statistically significant differences between the healthy and affected limbs in such directions as flexion, extension, abduction and internal rotation. .
