“…However, it is important to point out that the treatment of flat feet is indicated only in cases where 6-year-old children have pain and disability. Generally, conservative therapeutic options are used, such as orthotic devices, although in even more complex and refractory cases the only solution is surgery [22].…”

Objective To determine whether asymptomatic flexible flat feet show specific postural assessment with respect to neutral feet in 6-year-old children.Methods In this cross-sectional observational study, 164 subjects were observed and divided into two groups: 57 with flexible flat feet and 107 with neutral feet. A non-quantitative inspection by podoscopy and baropodometry were performed to evaluate plantar support, and a clinical examination to assess postural setting.Results The prevalence of flexible flat feet was 34.8%. The differenceinthe mean centre of pressure (CoP) between the two groups was significant (p=0.028), regarding the antero-posterior direction of CoP only. There was no significant differencein the presence of postural growth disharmony between the neutral and flat-feet groups.Conclusion The flattening of the plantar archseems to be linked to a displacement of CoP Y, more posterior in flat feet than in neutral feet; on the other hand, postural harmony in 6-year-old children during growth is not influenced by flat feet.

“…Therefore, we propose our own vision of this problem, which is based on a theoretical and practical basis on the unity of anatomic-biomechanical factors, which is clearly presented in the theory of myofascial kinematic chains. According to this theory [7,20,21], all groups of the leg muscles and their own muscles of the foot are involved in the formation and retention of the vaulted apparatus of the foot [2].…”

The aim of the work is to study the biomechanical properties of the myo-fascial kinematic chain "foot-shin" of children of 7-14 years old with non-fixed and clinically expressed flat-footedness.Material and methods. The study involved 14 children with flat-footedness of grades I-II and 6 children with flat-foot deformity of the foot and 20 children who only had functional disorders of the foot. An anthropometric study of the foot was carried out, electrophysiological indicators of the muscles of the leg were determined, and plantograms were analyzed.Results. The study found a correlation between the indicators of the anatomical and functional state of the foot and the imbalance of the frequency-amplitude indices of the ipsi and contralateral muscles within one link of the myofacial kinematic chain, may be important as one of the factors that contribute to the development of flatfoot. This is confirmed by other indicators and indicate a decrease in the height of the longitudinal arch, a decrease in the metatarsal and heel angles of the arch of the foot. Such changes have a pronounced relationship with age. The results of the work indicate that a possible cause of flattening of the vaulted apparatus of the foot is not only the weakness of its joint-ligament-muscular system, but also above the located kinematic segment - the tibia. The correlation analysis revealed the relationship between the indicators of the development of the anatomical and biomechanical components of the foot and the characteristics of the electromyographic indicators of the muscles of the leg in children 7-14 years old. As a result of a comprehensive study, it was found that during this period of ontogenesis in the formation of flatfoot such electromyographic indicators as frequency-amplitude characteristics of action potentials of motor units of the long and posterior tibial muscles, as well as their tone imbalance, take on major importance.Conclutions. Experimental studies have established that the registered changes in the articular components of the foot of children 7-14 years old lead to a change in the electromyographic parameters of the muscles of the leg, which are involved in the formation of the initial sections of myo-fascial kinematic chains.

Objective To investigate differences in the relative sizes of the ankle-stabilizing muscles in individuals with versus without flexible flat feet and to determine predictors of symptom severity.Methods This cross-sectional study included 30 patients with symptomatic flexible flat feet and 24 normal controls. The following were evaluated: foot posture index, resting calcaneal stance position angle, radiographic findings (calcaneal pitch, Meary’s angle, talocalcaneal angle, talonavicular coverage angle [TNCA]), foot function index (FFI), and cross-sectional areas (CSA) of the tibialis anterior (TA), tibialis posterior (TP), and peroneus longus (PL) upon ultrasonographic examination. To address morphometric differences among participants, individual muscle measurements were normalized to proportions of total muscle CSA. Between-group differences were evaluated with independent t-tests. Correlations between muscle ratios, radiographic parameters, and FFI scores were investigated. Logistic regression analysis was performed to determine which parameters predicted severe symptoms.Results The relative size of the TP was significantly greater and those of the TA and PL were significantly smaller in patients with flat feet than in normal controls. Correlations were found among relative muscle CSA ratios, radiographic parameters, and FFI score. Linear regression analysis confirmed that the TNCA and the relative CSA of the PL were independent predictors of symptom severity.Conclusion This study found significant differences in the relative CSAs of the ankle muscles in patients with flexible flat feet versus individuals without flat feet; these differences were significantly correlated with anatomic abnormalities. Symptoms were more severe in patients with relatively greater forefoot abduction and relatively smaller PL.
