Summary

Individuals with foot-ankle problems (plantar fasciitis, metarsalgia, pes planus, pes planovalgus/varus) will be included in the study. Permission was obtained from the research group that developed the scale to use the Original Foot Posture Index-6 (FPI-6). Cross-cultural adaptation of the FPI-6 will be made in line with the guidelines published by Ruberto and Beaton. First of all, the FPI-6 will be translated into Turkish by two translators whose native language is Turkish and who can speak English at an advanced level. Translations will be compared and discussed, and a Turkish version will be obtained with the equivalents that best represent each item in the texts. Secondly, this retranslated text will be independently translated back into English by two native English translators. In the third stage, two texts written in English will be synthesized by the authors, thus reaching a consensus on a single translation. Finally, the inconsistent parts of the text will be checked by a multidisciplinary team consisting of two native English-speaking translators, members of the English language and literature department, authors who developed the scale, and physiotherapists. Two independent physiotherapists will evaluate the participants' foot posture indexes by FPI-6 for inter-rater reliability. In addition, patients' quality of life, foot functions, hindfoot profiles will be evaluated. For the calculation of validity between measurements, rater-1 will apply the FPI-6 again to the same participants after 15 days for intra-rater reliability. Patients' functional independence, activities of daily living, and quality of life will also be evaluated for criterion validity. American Orthopedic Foot and Ankle Society-AOFAS, SF-36 and Foot Function Index questionnaires will be applied for the validity of FPI-6.

DIAGNOSTIC_TEST

Foot Posture Index (FPI-6)

FPI-6 is a valid and reliable assessment tool for pediatrics in which 6 items are scored separately for the right and left feet while the patient was in an upright position in a relaxed posture with their body-weight evenly distributed on the both feet. Each item is scored as -2, -1, 0, 1, 2 and the assessment categorized as follows: 0 to +5 normal; +6 to +9 pronated; 10+ higly pronated; -1 to -4 supianted; and -5 to -12 higly supinated.
