“…In line with our hypothesis, we found that the AbH and FHB thickness and cross-sectional area were lower in individuals with HV compared to control group. Similar to our results, previous studies reported that individuals with HV had lower AbH and FHB cross-sectional area and thickness compared to healthy control 12, 13, 14. The results of the present study show that muscle strength of AbH and FHB muscles decrease in individuals with HV, because muscle size is an important determinant of muscle strength 9 .…”

“…In contrast with our results, Lobo et al 13 reported that PF thickness is increased in individuals with HV, while FDB thickness and cross-sectional area are similar in with and without HV. Mickle et al 12 found that FDB thickness and cross-sectional area were similar in individuals with HV compared with those without HV. Increase in FDB thickness and cross-sectional area may be a compensation or adaptation against mechanical changes in foot and decreased intrinsic muscle strength associated with HV.…”

“…There exist a few studies on the morphological features of foot muscles and PF in individuals with HV. These studies reported that individuals with HV had lower thickness and cross-sectional area of abductor hallucis and flexor hallucis brevis compared to individuals without HV 12, 13, 14. Even though a few studies in the literature investigate the intrinsic foot muscles and PF thickness and cross-sectional area in individuals with HV, to our knowledge, there exists no study investigating the stiffness of intrinsic foot muscles and PF in individuals with HV.…”

BackgroundThe aim of the present study was to investigate the morphologic features and mechanical properties of plantar fascia (PF), flexor hallucis brevis (FHB), flexor digitorum brevis (FDB), and abductor hallucis (AbH) muscles in individuals with halluks valgus (HV) and to compare the results with individuals without HV.MethodsA total of 30 participants (27 female, 3 male) between the ages of 19–58 years with HV deformity and 30 individuals without HV (27 female, 3 male) between the ages of 20–58 years were included in the study. AbH, PF, FHB, and FDB thickness, cross-sectional area and stiffness were measured with an ultrasonography device. For stiffness measurements, Shear Wave Velocity (SWV) of the assessed soft tissues was calculated using a customized software program.ResultsMean and standard deviation of SWV of PF, AbH, FHB, FDB, and thickness of PF, AbH, FHB, FDB, and cross-sectional area of AbH, FHB, FDB in individuals with HV were 7.6 ± 1.0 m/sec, 2.8 ± 0.3 m/sec, 2.6 ± 0.4 m/sec, and 3.4 ± 0.2 m/sec, 3.3 ± 0.5 mm, 11.4 ± 2.2 mm, 16.5 ± 1.9 mm, 8.9 ± 1.8 mm, 2.4 ± 0.5 cm2, 2.7 ± 0.5 cm2, 1.9 ± 0.6 cm2, respectively. Mean and standard deviation of SWV of PF, AbH, FHB, FDB and thickness of PF, AbH, FHB, FDB, and cross-sectional area of AbH, FHB, FDB in controls groups were 7.6 ± 1.2 m/sec, 2.3 ± 0.3 m/sec, 2.3 ± 0.4 m/sec, and 3.4 ± 0.4 m/sec, 3.3 ± 0.5 mm, 9.7 ± 2.1 mm, 14.5 ± 1.4 mm, 9.7 ± 1.2 mm, 2.1 ± 0.3 cm2, 2.3 ± 0.4 cm2, 2.1 ± 0.4 cm2, respectively. Individuals with HV had lower AbH and FHB thickness, cross-sectional area and SWV, however FDB thickness and cross-sectional area were higher in individuals with HV compared to that of individuals without HV (p < 0.05). PF thickness (p = 0.273), SWV of PF (p = 0.979) and FDB (p = 0.295) were similar in both groups.ConclusionOur results suggest that individuals with HV had lower AbH and FHB stiffness, however PF and FDB stiffness were similar in HV and control group. In addition, AbH and FHB thickness and cross-sectional area were lower in individuals with HV; however, FDB thickness and cross-sectional area were higher in individuals with HV compared to that of individuals without HV.Level of EvidenceLevel III, Diagnostic Study.

Bez obzira na ciljeve studije, bilo da se radi o morfološkoj klasifikaciji stopala ili prilagođavanju proizvoda poput ortopedskih uložaka / potplata ili prikladne obuće za atipična stopala, neophodno je pronaći racionalnu metodu za otkrivanje antropometrijskih točaka i krivulja. Studije o objašnjenju antropometrije stopala su malobrojne, a u nekim slučajevima predstavljaju suprotnosti mjerenjima između ručnog postupka i postupka automatskog skeniranja. Također, naš cilj bio je upotrijebiti beskontaktnu metodu mjerenja da se otkriju antropometrijske točke na stopalu. U ovoj metodi se predlažu različite tehnike praćenja pomoću različitih podesivih ravnina. U 3D grafičkom procesu, morfološke krivulje su lokalizirane pomoću tih antropometrijskih točaka i omogućuju identifikaciju stopala tim mjerenjima. Ona su uspoređena s mjerenjima pomoću 3D skenera stopala da bi se metoda otkrivanja antropometrijskih točaka mogla potvrditi i poboljšati metoda koju koriste ovi skeneri.

“…Therefore, strengthening the intrinsic toe muscles may help reduce the incidence and severity of toe deformities in older adults [9]. Shoes and insoles need to conform to the wearer's foot shape without squeezing or pressing any part of the foot [10].…”

Regardless of the objectives of the study, whether it is the morphological classification of the feet or the customization of products such as orthopedic insoles or appropriate footwear for atypical feet, it is the imperative to find a rational method for detecting the anthropometric points and curves. The studies explaining the anthropometry of the foot are very few and in some cases present contradictions in the measurements between the manual and automatic scanning processes. In addition, our goal was to implement a non-contact measurement method to detect the anthropometric points of feet. This method proposes different tracking techniques using different adjustable planes. In a 3D graphical process, the morphological curves have been located with the help of these anthropometrics points and allowed the identification of the foot by their measurements. These measurements were compared with those obtained by a 3D foot scanner to validate the detection method of anthropometric points and improve it by employing these scanners.
