OBJECTIVE:To evaluate and compare rearfoot alignment and medial longitudinal arch index during static postures in runners, with and without symptoms and histories of plantar fasciitis (PF).INTRODUCTION:PF is the third most common injury in runners but, so far, its etiology remains unclear. In the literature, rearfoot misalignment and conformations of the longitudinal plantar arch have been described as risk factors for the development of PF. However, in most of the investigated literature, the results are still controversial, mainly regarding athletic individuals and the effects of pain associated with these injuries.METHODS:Forty-five runners with plantar fasciitis (30 symptomatic and 15 with previous histories of injuries) and 60 controls were evaluated. Pain was assessed by a visual analogue scale. The assessment of rearfoot alignment and the calculations of the arch index were performed by digital photographic images.RESULTS:There were observed similarities between the three groups regarding the misalignments of the rearfoot valgus. The medial longitudinal arches were more elevated in the group with symptoms and histories of PF, compared to the control runners.CONCLUSIONS:Runners with symptoms or histories of PF did not differ in rearfoot valgus misalignments, but showed increases in the longitudinal plantar arch during bipedal static stance, regardless of the presence of pain symptoms.
Objetivo: O propósito deste estudo foi avaliar a confiabilidade inter e intra-examinador da fotopodometria, bem como a confiabilidade intra-examinador da fotopodoscopia. Método: Foram fotografadas as impressões plantares de 30 indivíduos hígidos de ambos os sexos, com idade média de 21,0 ±1,32 anos, posicionados sobre um podoscópio, com os pés descalços, apoio bipodal e postura ortostática. A imagem da impressão plantar refletida no vidro desse aparelho foi capturada por meio de uma câmera fotográfica digital de 2.1 megapixels, posicionada sobre um tripé em frente ao mesmo. As imagens foram arquivadas e, em seguida, submetidas às análises inter e intra-examinador. Para verificar a confiabilidade intra-examinador da fotopodoscopia, após quatro semanas, toda a metodologia de captura e análise de novos podogramas dos mesmos indivíduos foi repetida. Resultados: As análises inter e intra-examinador da fotopodometria apresentaram, respectivamente, ICC= 0,96 e ICC= 0,98. O ICC de confiabilidade intra-examinador da fotopodoscopia foi de 0,94. Conclusão: Conclui-se então que a fotopodometria é um recurso de análise quantitativa confiável, sendo também a fotopodoscopia um método de avaliação aplicável para análises clínicas e científicas, permitindo, assim, acompanhar a evolução de tratamentos fisioterapêuticos dos apoios plantares, mesmo levandose em consideração as variabilidades intrínsecas e extrínsecas dos indivíduos.
