PEZZAN, Patrícia A. O.; SACCO, Isabel C. N.  and  JOAO, Silvia M. A.. Foot posture and classification of the plantar arch among adolescent wearers and non-wearers of high-heeled shoes. Rev. bras. fisioter. [online]. 2009, vol.13, n.5, pp.398-404.  Epub Nov 06, 2009. ISSN 1413-3555.

OBJECTIVES: To investigate the relationship between foot posture and plantar arch among adolescent wearers and non-wearers of high-heeled shoes. METHODS: Thirty-six female adolescents aged 13 to 20 years were selected and grouped as 16 high-heel non-wearers and 20 high-heel wearers. Foot posture was analyzed using photos, firstly barefoot and, secondly, after wearing previously standardized high-heeled platform shoes for an hour. The analysis was performed using the software SAPo. Barefoot impressions were taken, and the Chipaux-Smirak Index was calculated to classify the plantar arch of the foot. For statistical analyses, the paired t test was used to investigate equality between the right and left sides. The Shapiro-Wilk adherence test was performed, followed by inferential analysis using the non-parametric Wilcoxon test, the Mann-Whitney test and Spearman's correlation coefficient. The significance level used was 0.05. RESULTS: There was no correlation between the type of plantar arch and foot posture among the female adolescents studied. However, the rearfoot angle was significantly different, with rearfoot varus after wearing the shoes in both groups. The plantar arch in the wearers group presented smaller values for the Chipaux-Smirak Index. CONCLUSIONS: There is no correlation between foot posture and the type of plantar arch, although these variables are influenced by high-heeled shoes.
