However, the accompanied complications will limit its use for epidemiological studies and research purposes, especially in children.&nbsp; Therefore, simple, accessible, and cost- effective methods such as footprint, with a good correlation with x-ray images, are needed to help diagnose different foot pathologies. In the present study, the accuracy of footprint technique in assessing hallux valgus angle (HVA) was evaluated based on x-ray images through measuring the angle between the medial border protrusion of the foot and the hallux.<br> <strong>&nbsp;&nbsp; Methods:</strong> In this cross-sectional study, 42 participants with symptomatic hallux valgus were recruited. HVA was measured by both x-ray imaging and footprint. The differences between the two approaches were identified by applying correlation-coefficient test and reliability, which was assessed using interclass correlation (ICC).<br> <strong>&nbsp;&nbsp; Results:</strong> A significant correlation was found between the HVA measured by x-ray and HVA by footprints (p<&thinsp;0.001), and the ICC was upper than 90%.<br> <strong>&nbsp;&nbsp; Conclusion:</strong> Foot print is a reliable method for measuring HVA, as it was highly correlated with the HVAs obtained by x-ray imaging.&nbsp;<br> &nbsp;</p> Hallux valgus angle, X-ray, Foot print 192 195 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-1292-1&slc_lang=en&sid=1 Ensieh Pourhoseingholi ensiehpmd@yahoo.com 200319475328460033707 200319475328460033707 No Department of Orthotics & Prosthetics, School of Rehabilitation Sciences, Iran Univer-sity of Medial Sciences, Tehran, Iran.
