Estudo da impressão plantar obtida durante o teste de Jack em crianças

Abstract

Objective: To assess the plantar impressions obtained in children during the Jack test, with the aim of quantifying and analyzing their variability in the critical period for plantar foot arch formation. Method: A hundred and twenty feet from 60 healthy White children, recruited in an outpatient pediatric clinic, were examined. Our sample included 35 boys and 25 girls, ranging from 2 to 5 years. The Jack test was simulated using a 45o wedge-shaped orthosis applied to the hallux. Bilateral plantar impressions were acquired in the alternate single-foot standing position using a pedigraph. Two plantar impressions were obtained for each foot, with and without the orthosis. The exams were analyzed using the Valenti and Volpon methods. Statistical tests were applied. Results: In all cases, both the Valenti and Volpon indexes decreased as the orthosis was applied. Furthermore, the difference between both indexes with and without the orthosis decreased with age. Conclusions: It is possible to quantify the Jack test using plantar impressions with the Volpon and Valenti methods. The variability observed in plantar shape tended to decrease after 4 years of age. Finally, the Jack test gradually lost its capability to change plantar impression with age, which reduces its accuracy as a parameter for a good prognosis in longitudinal medial arch formation. Level of Evidence: Level IV, observational descriptive study.

The typically developing paediatric foot: how flat should it be? A systematic review

“…Little can be inferred from comparative mean, SD and 95% CI data presented within Fig. 11, with only two authors reporting data from the Contact Index II [27, 47]. Data is suggestive only of a higher index value at 3.5 years of age and a lower index value at 8.63 years of age.…”

“…The following proportions for foot type were determined in their cohort; 0% high arch, 23% normal, 46% low arch and 31% flat foot type. Pinto et al present the data for the Valenti index, another foot print based indices [47]. In their Brazilian cohort of children aged 2–5 years of age the Valenti index was reported to be a mean of 0.54 (0.17) for left feet and 0.55 (0.17) for right feet.…”

Correlação entre alterações lombares e modificações no arco plantar em mulheres com dor lombar

“…The feet can be classified according to the changes in their arches since when they start to form in early childhood 15 . The flat foot is characterized by the partial or total collapse of the medial longitudinal arch.…”

“…The feet can be classified according to the changes in their arches since when they start to form in early childhood. 15 The flat foot is characterized by the partial or total collapse of the medial longitudinal arch. The debility of its means of support may be related to musculoligamentous insufficiency, especially of the tibialis anterior and posterior and fibularis longus muscles, resulting in flexible or hypermobile feet.…”

Caracterização das impressões plantares em escolares: influência da idade e do indice de massa corporal

“…CONCLUS\u00d5ES: Observou-se que o ALM se forma mais tardiamente em crian\u00e7as obesas (8 para 9 anos A plantigrafia é umas das formas de avaliação dos pés, considerada um método prático e viável para avaliação do ALM dos pés 10. Por meio do registro da impressão plantar, podem ser observadas áreas de contato e de ausência de contato, formando um desenho do pé humano 11. Neste contexto, as avaliações realizadas na escola para o acompanhamento do desenvolvimento e do crescimento de crianças e de adolescentes são essenciais para identificação de alterações nesses aspectos, tendo em vista os valores já preditos para essa população.…”
