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: Crosssectional 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 measurements. 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.
