Translation, Cross-cultural Adaptation, and Validation of the FPI-6 in Spain

Summary

The objective of this study is to translate, cross-culturally adapt, and validate the Spanish version of the Foot Posture Index (FPI-6). This clinical tool is widely used to evaluate standing foot posture through six visual criteria. The study aims to provide Spanish-speaking clinicians and researchers with a reliable and valid instrument to assess foot posture in the Spanish population, ensuring that the psychometric properties of the original scale are preserved

Conditions

• Foot Deformities
• Flatfoot

Interventions

OTHER

Spanish version of the Foot Posture Index (FPI-6)

The assessment consists of the clinical application of the Spanish version of the Foot Posture Index (FPI-6). This is a non-invasive observational method where the investigator evaluates six specific criteria of the foot while the participant stands in a relaxed position. The six criteria include: talar head palpation, supra and infra-malleolar curvature, calcaneal frontal plane position, prominence in the region of the talonavicular joint, congruence of the internal longitudinal arch, and abduction/adduction of the forefoot on the rearfoot. Each item is scored between -2 and +2, providing a total score between -12 and +12

Clinical assessment of standing foot posture using the Spanish translation of the Foot Posture Index (FPI-6). This tool evaluates six criteria: talar head palpation, supra and infra-malleolar curvature, calcaneal frontal plane position, prominence in the region of the talonavicular joint, congruence of the internal longitudinal arch, and abduction/adduction of the forefoot on the rearfoot. Each item is scored on a scale from -2 to +2. The tool will be applied to a sample of children (from 5 years old) and adults to evaluate its psychometric properties, including reliability and internal consistency
