RT Journal Article T1 The resting calcaneal stance position (RCSP): an old dog, with new tricks A1 Martinez Sebastian, Carlos A1 Gijon Nogueron, Gabriel A1 Ramos Petersen, Laura A1 Molina Garcia, Cristina A1 Sánchez Gómez, Rubén A1 Evans, Angela M. AB The objective of this study was to establish the accuracy of the resting calcaneal stance position (RCSP) for the assessment of flat foot (FF) in children, aligned to the validity of the foot posture index (FPI). The RCSP cut-off point was explored, in context of both FF prevalence and the relationship between FF and body weight. A total of 205 healthy children, aged 5 to 10 years, participated in a cross-sectional study. Correlation was performed between RCSP and FPI. ROC curve technique was calculated to assess differentiation between groups. A score equal to or greater than 7 on the FPI was used as the ‘gold standard’ for analysis. The correlation between FPI and RCSP was significant (r = 0.63; p < 0.01). The discrimination score on the ROC curve (6 points/degrees) shows that the model can be used to identify FF through RCSP, with a sensitivity of 67% and specificity of 85% returned.ConclusionThe results of this study indicate the role of RCSP for simple, accessible and quick screening of paediatric FF. This is especially pertinent for non-podiatric healthcare professional without specialised paediatric foot knowledge.
