Abstract

Introduction: Improper hip joint development may lead to numerous unfavourable changes in the musculoskeletal system. The aim of this research was to determine how often adolescents with idiopathic scoliosis and their healthy counterparts experienced anomalies of the hip in their infancy period and to examine the correlation between the occurrence of hip anomalies and idiopathic scoliosis. Material and methods: The research was conducted in medical centres as well as in schools. The parents of adolescents with idiopathic scoliosis and parents of healthy adolescents completed a questionnaire on the basis of their child’s development history included in the medical records book and other medical documentation. Results: 533 questionnaires were taken into consideration, included 145 questionnaires completed by parents of adolescents with scoliosis (121 girls - 13.8 years, SD 1.9; 24 boys - 12.9 years, SD 2.5) and 388 questionnaires from the group of adolescents without scoliosis (194 girls - 13.5 years, SD 2.0; 194 boys - 13.4 years, SD 2.1). No significant differences were noted in the incidence of hip anomalies between the groups of girls and boys with and without scoliosis, no correlations between anomalies of the hip and scoliosis were found (girls χ2=0.840; Cramer V=0.052; p=0.36; boys χ2=1.205; Cramer V=0.074; p=0.27). Conclusions: Hip anomalies such as hip dysplasia, movement asymmetry or range of motion limitations diagnosed in the infancy period did not correlate with idiopathic scoliosis. Further research aimed at a separate analysis of the influence of hip dysplasia on the occurrence of idiopathic scoliosis should be carried out.

Summary

Study aim: Premature birth is one of the major problems of obstetrics, leading to numerous complications that are associated with prematurity, for instance balance disorders. The aim of the study was to assess the impact of premature birth on the ability to maintain balance in children commencing their school education. Material and methods: The study included children aged 6-7 years. The study group consisted of 59 children (31 girls and 28 boys, mean age 6.38 ± SD 0.73) born prematurely between 24 and 35 weeks of gestation. The control group consisted of 61 children (28 girls and 33 boys, mean age 6.42 ± 0.58) born at term. The research utilized standardized test tools - one-leg open-eyed and closed-eyed standing test, one-leg jumping test - and an original questionnaire survey. Results: The children born at term achieved better results in the majority of tests. The comparison of girls and boys born pre­maturely and at term showed no statistically significant difference between them in terms of dynamic balance, static balance or total balance control. The comparison of the tests performed on the right and left lower limb in prematurely born children showed no statistically significant differences. Conclusion: Premature birth affects the ability to maintain body balance. The results of the study indicate the need to develop coordination skills that shape body balance in prematurely born children.

Abstract

Introduction: The Trunk-Pelvis-Hip Angle (TPHA) test is used for assessing the mobility of lumbo-pelvic-hip complex. The aim of the research was to assess the intraobserver reliability of the TPHA test in girls with and without idiopathic scoliosis and to compare the test values obtained by the girls in both groups.

Material and methods: The research included girls without scoliosis and girls with double idiopathic scoliosis aged 8-16. The trunk-pelvis-hip angle was measured three times on each body side within one session. Statistical analysis was performed with the use of ANOVA intraclass correlation coefficient for dependent groups, Kolmogorov-Smirnov test as well as non-parametric Wilcoxon signed-rank test for dependent groups and Mann-Whitney U test for independent groups.

Results: The research included 49 healthy girls (aged 11.8 ± SD 2.5 years) and 49 girls with double idiopathic scoliosis (aged 12.7 ± SD 2.6 years; Cobb angle Th 27.7° ± SD 13.4° and L Cobb 25.8° ± SD 10.5°). The intraobserver reliability for the TPHA measurements was very high (ICC>0.85). In both groups the left-side TPHA value was significantly higher than the right-side value (p=0.001). The TPHA range of motion on the right side of the body was more limited in the scoliotic girls than in the healthy ones (p=0.001).

Conclusions: The TPHA test is a reliable means of assessing mobility in the lumbo-pelvic-hip complex in girls by one observer. The asymmetry of movements in the lumbo-pelvic-hip complex in healthy girls needs to be observed since it may constitute one of the factors predisposing to scoliosis which limits spine rotation range of motion. The TPHA test needs further research.
