Introduction: Changing in the structure of the sole of the foot, including increasing or decreasing its arch, is one of the factors that expose the foot to injuries caused by physical activities. Therefore, the aim of the current study was to determine the relationship between strength of central muscles, coordination, stability and functional movement scores in females with flexible flatfeet.
Methods: Ninety-six female students between the ages of 18 and 25 voluntarily participated in this study. The Navicular Drop Test was used to evaluate the longitudinal arch of the foot. The participants were classified into flexible flatfeet (n=25) and normal feet (n=71) groups. Fundamental movement evaluated by the Functional Movement Screening Test (FMS); static balance using the Sharpened-Romberg test; dynamic balance using Y-test; Agility and coordination using 4×9-m shuttle run; endurance of the abdominal muscles and lumbar spine extensor muscles using respectively Partial curl-up and maintaining the plank position, were evaluated.
Results: The results of the independent t-test and Mann-Whitney U test showed a significant difference between the two groups in functional movement, abdominal muscle endurance, static balance and lumbar extensor muscle endurance variables (p≤0.05). In the normal feet group, a significant correlation was found between functional movements with abdominal muscle endurance, dynamic balance and agility.
Conclusion: the deformity of flexible flatfeet lead to deficiencies in people's health, movement performance and motor skill-related factors; therefore, according to this study, patients should be aware of this potential deficiency and paying attention to appropriate rehabilitation exercises for the conservative treatment of flexible flatfeet.
