All methods present several limitations depending on the examiner or the chosen test. This study aims to investigate the relationship between different tests and Footprints parameters to diagnose subjects with a flat and neutral foot. Methods: The sample consisted of 37 participants, where 16 were included in the flatfoot group and 21 in the neutral foot group. Only subjects who presented a Navicular Drop Test value of &gt;9 mm were included in the flatfooted group. All participants were submitted to Resting Calcaneal Stance Position and plantar pressure platform assessment for Footprints analysis. Associations between all tests and Footprints parameters were determined by Pearson\u2019s correlation analysis. Results: Regarding both groups, significant correlations between tests were moderate to nearly perfect to identified both conditions of foot posture. All correlations were statistically significant (p &lt; 0.05). Conclusions: The diagnosis accuracy of foot posture condition can be compromised depending on the used test. The Navicular Drop Test and the Resting Calcaneal Stance Position were shown to mislead foot posture condition assessment, unlike Footprints parameters that can be important evaluation tools in a clinical environment.<\/jats:p>","DOI":"10.3390\/j4030019","type":"journal-article","created":{"date-parts":[[2021,6,24]],"date-time":"2021-06-24T04:24:36Z","timestamp":1624508676000},"page":"233-243","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Correlation between Different Methods to Diagnose Foot Posture Condition"],"prefix":"10.3390","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9998-4702","authenticated-orcid":false,"given":"Joel","family":"Marouvo","sequence":"first","affiliation":[{"name":"RoboCorp Laboratory, i2A, Polytechnic Institute of Coimbra, 3045-093 Coimbra, Portugal"},{"name":"Faculty of Sports, University of Porto, 4200-450 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1500-355X","authenticated-orcid":false,"given":"Maria Ant\u00f3nio","family":"Castro","sequence":"additional","affiliation":[{"name":"Sector of Physiotherapy, School of Health Sciences, Polytechnic Institute of Leiria, 2411-901 Leiria, Portugal"},{"name":"Centre for Mechanical Engineering, Materials and Processes (CEMMPRE), University of Coimbra, 3030-788 Coimbra, Portugal"}]},{"given":"Carlos","family":"Santos","sequence":"additional","affiliation":[{"name":"BodyKeeper Carlos Morgado Santos-Physiotherapy, Osteopathy, and Posturology Clinic, Nutrition and Psychology, 3030-489 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4084-1942","authenticated-orcid":false,"given":"Filipa","family":"Sousa","sequence":"additional","affiliation":[{"name":"Faculty of Sport (FADEUP), CIFI2D, University of Porto, 4200-450 Porto, Portugal"},{"name":"Porto Biomechanics Laboratory (LABIOMEP-UP), University of Porto, 4200-450 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"742","DOI":"10.1053\/j.jfas.2017.12.019","article-title":"The Sensitivity of Thresholds by Ground Reaction Force and Postural Stability in Subjects with and Without Navicular Drop","volume":"57","author":"Sung","year":"2018","journal-title":"J.
