Increased Femoral Anteversion and Physical Performance
Study Details
Study Description
Brief Summary
It is important to determine how high femoral anteversion, which is one of the lower extremity malalignments, affects physical performance and to what extent it affects the daily life of the individual. As far as we know, there is no study on this subject except for a study conducted by Staheli et al. in 1977. Therefore, the investigators planned to determine whether and to what extent high femoral anteversion has an effect on physical performance in healthy young adults.

Detailed Description
One of the factors associated with problems in the lower extremity is changes in the angle of femoral anteversion. High femoral anteversion causes pathological changes in the sagittal and coronal planes, especially in the transverse plane, and changes the gait biomechanics. Femoral anteversion angle; It is the angle formed by the plane of the femoral condyle and the plane passing through the femoral neck and the femoral head. The femoral anteversion angle, which is 55°-60° in the intrauterine period, is approximately 30° at birth. In the postnatal period, with normal growth, it decreases by 1.5° per year until the age of 15, decreasing to 26° at the age of 5, 21° at the age of 9 and 15° at the age of 16.
Toe-in gait pattern may be due to foot deformity (metatarsus adductus) and/or transverse alignment disorder of the long bones (tibial torsion and/or femoral anteversion height). When the angle of anterversion is high, walking with the feet turned in is 30.9% at the age of 4, 15% at the age of 4, and around 4% in adults. High femoral anteversion, which is the most common cause of inward walking in early childhood, is mostly seen symmetrically, with a higher incidence in girls and hypermobile children. Most cases are idiopathic and some patients have a familial predisposition.
Alignment disorders in the lower extremities can cause problems affecting other segments of the body, postural disorders and problems in the musculoskeletal system, as well as affect physical performance. The study, which will examine the physical performance status of young adults with high femoral anteversion, will be carried out as a cross-sectional study. The universe of the study will consist of students aged 17-26 who continue their education at the Faculty of Health Sciences of Bezmialem Vakıf University in the 2022-2023 academic year. Within the scope of our cross-sectional study, an application will be made for the approval of the Ethics Committee before the data are collected. The study, which will start after the permission is obtained, will be carried out in accordance with the Declaration of Helsinki. Evaluation and testing of all cases will be done at Bezmialem Vakif University, Faculty of Health Sciences, Department of Physiotherapy and Rehabilitation. 22 subjects with high femoral anteversion angle and 22 subjects with normal femoral anteversion angle will be included in the study. Within the scope of the study, demographic information of all participants will be obtained with the evaluation form and clinical evaluations will be made. Flexibility with sit-reach test, hand grip strength with hydraulic hand dynamometer, general muscle strength with analog back-leg-chest dynamometer, functional performance with single-leg and double-leg horizontal jump tests, and functional capacities with 6-minute walking test will be evaluated. "Statistical Package for the Social Sciences (SPSS) 20.0 for Windows" package program will be used in the statistical analysis of the data obtained from the study which the investigators planned to evaluate physical performance in young adults with high femoral anteversion. All data will be analyzed with the Kolmogorov-Smirnov test to determine the distribution characteristics. In the study, descriptive statistics (mean±standard deviation, minimum-maximum, number and percentile) will be given for discrete and continuous variables. When the differences between two independent groups are evaluated, "t-Test in Independent Groups" in case the parametric test prerequisites are met; If not, the "Mann Whitney -U Test" will be used. "Chi-Square Test" will be used to determine the relationships between two discrete variables. When the variables meet the parametric test prerequisites, the correlation coefficients and statistical significance will be calculated with the "Pearson Test", when they do not, the correlation coefficients and statistical significance for the relations between the variables will be calculated with the "Spearman Test".
