    Introducción: Los estudios dinámicos de la función del pie habitualmente se realizan en laboratorios de marcha de gran complejidad. El objetivo de este estudio fue analizar parámetros funcionales utilizando una plataforma de fuerza en una serie de pacientes asintomáticos evaluados en consultorios externos.

    Materiales y Métodos: Estudio de corte transversal que incluyó una serie consecutiva de pacientes asintomáticos voluntarios a quienes se les realizó una medición con una plataforma de fuerza (TekScan MatScan®, Boston, MA, EE.UU.) entre 2014 y 2020, en la Ciudad Autónoma de Buenos Aires, Argentina.

    Resultados: Se incluyeron 316 registros de 158 pacientes con mediciones bilaterales. La mayoría eran mujeres (66,5%) y el promedio de la edad era de 47 años (DE 16.1). Se evaluaron 14 variables, correspondientes a parámetros de fuerza, trayectoria y tiempo de contacto de la fuerza. El tiempo de contacto total fue de 0,79 segundos (DE 0,09), el CoF time según la región del pie fue del 20% en el talón, 26% en el mediopié y 46% en el antepié. El CPEI (center of pressure excursion index) fue del 16,55% (DE 7,14).

    Conclusiones: Se comunican los parámetros funcionales del pie en pacientes asintomáticos. Se midieron el tiempo de contacto del pie en el suelo, la fuerza (en talón, mediopié y antepié) y la trayectoria de la fuerza con una plataforma de fuerza. No se utilizaron radiaciones ionizantes. Estos hallazgos podrían ser utilizados como valores de referencia para detectar marchas patológicas.

    Introduction: Dynamic studies of foot function are usually carried out in highly complex gait analysis laboratories. The objective of this study was to analyze functional parameters using a force platform in a series of asymptomatic patients evaluated in an outpatient clinic. materials and methods:Cross-sectional study, which included a consecutive series of volunteer asymptomatic patients who underwent a force platform measurement (TekScanMatScan®, Boston, MA, USA) between 2014 and 2020, in the City of Buenos Aires, Argentina. Results: 316 records were included, corresponding to 158 individuals with bilateral measure-ments. Most were women (66.5%), with a mean age of 47 years (SD 16.1). Fourteen variables were evaluated, corresponding to parameters of force, trajectory, and contact time. The total contact time was 0.79 seconds (SD 0.09), and the COF time according to the region of the foot was 20% in the heel, 26% in the midfoot, and 46% in the forefoot. The CPEI (Center of Pressure Excursion Index) value was 16.55% (SD 7.14). Conclusion:Foot functional parameters in asymptomatic patients are presented. The contact time of the foot on the ground, the force in the heel, midfoot, and forefoot, and the force trajectory were measured. No ionizing radiation was used. These findings could be used as reference values to detect pathological gaits.
