About this trial
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
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Participants aged between 6 and 89 years
Ability to understand and sign the informed consent form. In the case of minors, written informed consent from parents or legal guardians and child's assent (where applicable) are required
Ability to maintain a relaxed standing position unassisted for the duration of the clinical assessment
Disqualifiers
History of major surgery or significant trauma in the lower limbs or feet.
Presence of open wounds or active skin infections on the feet at the time of the examination.
Neurological or musculoskeletal conditions that severely affect balance or standing posture.
Cognitive impairment that prevents the participant from following simple clinical instructions
Trial population
The study population consists of individuals from the general population in Spain, covering a wide age range that includes children (from 6 years old), adults, and the elderly (up to 89 years). Participants are recruited through convenience sampling from university clinics and local community centers to ensure a diverse representation of foot types (neutral, pronated, and supinated) across different stages of life

Treatments tested in this trial
Spanish version of the Foot Posture Index (FPI-6)
Other interventionThe 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
Spanish version of the Foot Posture Index (FPI-6)
Other interventionClinical 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
Treatment groups
Trial outcomes
Primary outcomes
Intra-rater and Inter-rater Reliability of the Spanish FPI-6
Consistency of the Foot Posture Index (FPI-6) scores evaluated through the Intraclass Correlation Coefficient (ICC). Intra-rater reliability will be assessed by one examiner repeating the test after 1-2 weeks. Inter-rater reliability will be assessed by two examiners evaluating each subject with a one-hour interval.
Internal Consistency of the Spanish FPI-6
Measured using Cronbach's alpha to ensure that all six items of the FPI-6 contribute coherently to the total score. A value \> 0.70 is expected.
Secondary outcomes
Criterion Validity
Correlation of the Spanish FPI-6 total score with the Foot Function Index (FFI) and the American Orthopaedic Foot and Ankle Society (AOFAS) scale using Spearman's correlation
