“…the angle of the varus deformity of the fifth toe (β)–(defines the position of the big toe)–it is located between the tangent line to the lateral edge of the foot and the tangent to the pad of the fifth toe, derived from the mtf point ( Fig 1C ), in degrees [ 9 – 14 ].…”

ObjectiveUnderstanding the factors and mechanisms that determine balance in seniors appears vital in terms of their self-reliance and overall safety. The study aimed to determine the relationship between the features of feet structure and the indicators of postural stability in the elderly.MethodsThe study group comprised 80 seniors (41F, 39M; aged 75–85 years). CQ-ST podoscope and the CQ-Stab 2P two-platform posturograph were used as primary research tools. The data were analyzed based on Spearman’s rank correlation and forward stepwise regression.ResultsAnalysis of forward stepwise regression identified the left foot length in females and Clarke’s angle of the left foot in men as significant and independent predictors of postural up to 30% of the variance of dependent variables.ConclusionsLonger feet provide older women with better stability, whereas in men, the lowering of the longitudinal arch results in postural deterioration. In the elderly, the left lower limb shows greater activity in the stabilizing processes in the standing position than the right one. In gerontological rehabilitation special attention should be paid to the individually tailored, gender-specific treatment, with a view to enhancing overall safety and quality of seniors’ lives.

“…The fact that so few adults boast functionally efficient feet nowadays is not only attributable to various ailments and physical injuries sustained throughout one's lifetime, but also to wearing ill-fitting footwear. Children are especially prone to be affected by many environmental factors in their adolescence, most of them of lifestyle origin [14,[16][17][18].…”

“…The Clarke angle values were the basis for the assessment of the longitudinal arch of the foot. Hence, flat foot occurs in the range < 30°, foot with a reduced arch 31°-41°, properly arched foot 42°-54°, and foot with a raised arch > 55° [3,[12][13][14].…”

Introduction:The WHO Health Behaviour in School-aged Children study (2018) on the health status of adolescents in Europe highlights an escalation of factors instrumental in the development of postural defects, which may consequently deteriorate into serious postural complaints in adulthood. Aim of the research:To investigate the correlations between the morphological structure of the foot and postural stability in children and adolescents. Material and methods:The study sample comprised 627 children (aged 10-15 years), who had the plantar part of their feet assessed in static conditions with a 2D Podoscan. Individual foot loading paradigm variables were assessed with a baropodometric platform. Postural assessment was completed with 2D Videography, facilitating morphological measurements of body asymmetry. Results: Valgus of the knees, Clarke's left foot angle, and Wejsflog index values also doubled as strong predictors of centre of the foot's pressure (COP) length. A negative correlation was established between the COP length and obesity, hallux valgus of the left foot, flat-footedness, and lowered longitudinal foot arches. Conclusions: Higher COP surface area values were observed in the children affected by valgus of the knees, higher angle of the hallux valgus in the left foot, and those with longer feet. Clarke's L-foot angle, Wejsflog index, and valgus of the knees proved to be strong predictors affecting key postural stability variables. StreszczenieWprowadzenie: Badanie WHO Health Behaviour in School-aged Children (2018) dotyczące stanu zdrowia nastolatków w Europie wskazuje na eskalację czynników przyczyniających się do rozwoju wad postawy, które mogą przeradzać się w poważne dolegliwości w wieku dorosłym. Cel pracy: Zbadanie zależności między budową morfologiczną stopy a stabilnością postawy u dzieci i młodzieży. Materiał i metody: W badaniu wzięło udział 627 dzieci (w wieku 10-15 lat), u których oceniano podeszwową część stóp w warunkach statycznych za pomocą podoskanu 2D. Poszczególne zmienne obciążenia stopy analizowano za pomocą platformy baropodometrycznej. Ocenę postawy uzupełniono wideografią 2D, ułatwiającą morfologiczne pomiary asymetrii ciała. Wyniki: Koślawość kolan, kąt Clarke'a stopy lewej i wartości wskaźnika Wejsfloga to silne predyktory wpływające na długości COP. Stwierdzono ujemną korelację między długością COP a otyłością, paluchem koślawym lewej stopy, płaskostopiem i obniżonymi podłużnymi łukami stopy. Wnioski: Wyższe wartości pola powierzchni COP zaobserwowano u dzieci z koślawością kolan, większym kątem palucha koślawego w stopie lewej oraz u dzieci z dłuższymi stopami. Kąt L-stopy Clarke'a, indeks Wejsfloga i koślawość kolan okazały się silnymi czynnikami prognostycznymi wpływającymi na kluczowe zmienne stabilności postawy.

“…The longitudinal arch was assessed on the basis of the Clarke’s angle value, assuming that a flat foot is construed within the > 30° range, a foot with a reduced arch - 31° - 41° range, a correctly arched foot - 42° - 54° range, and a foot with a raised arch - < 55°. Whilst taking into account the Clarke’s angle values we were able to determine whether the foot under study was flat, correctly structured, or whether it was a cavusfoot [19]. The transverse arching was evaluated using the Wejsflog index (length/width of the foot, ratio 3:1).…”

BackgroundChildren and young people make up an age group most vulnerable to falls. Various stability disorders may become instrumental in sustaining more frequent falls and resultant fractures. Correct morphological structure impacts overall efficiency of the foot, as well as offers significant diagnostic potential. Even minor foot disorders may affect the entire bio kinematic chain, also impacting the foot’s motility. Structural alterations within a foot may also impair balance in the standing position, and contribute to more frequent injuries. The study aimed to assess the relationship between feet deformities and postural stability deficits in schoolchildren prone to sustain accidental falls.MethodsThe study involved 200 children (101 girls and 99 boys) aged 10–15 years,randomly selected from primary schools. A 2D podoscan was used to assess the plantar part of the foot, while stabilometric examination was aided by the FreeMed dynamometric platform.ResultsCorrelation between respective variables was reflected by Spearman’s rank coefficient. The subjects’ age negatively correlated with the COP range of movement along the Y axis, and the COP surface area, while their BMI negatively correlated with the COP trajectory’s length. Step regression analysis indicated that the width of the left foot, the left foot Wejsflog index, the left foot Clark’s angle, the hallux valgus angle were the essential predictors of stabilometric variables in girls. In boys, though, predictive value was associated with Clarke’s angle of the left and right foot, Wejsflog index of the right foot, and the width of both the left and right foot.ConclusionsThere is a statistically significant correlation between morphological variables of the foot and postural stability. When assessing the key variables of the foot and their interrelationship with postural stability, the Clarke’s angle, Wejsflog index, hallux valgus angle, and foot width, should be granted due prominence in the girls. As regards the boys, the following variables were established as predictive in assessing postural stability: Clarke’s angle, Wejsflog index, and foot width.
