[Determination of plantar pressure in people who use orthoses of the foot].

OBJECTIVE To know the transfer of static plantar pressures and body weight distribution through the lower limbs that occur in people with and without the use of orthoses of different densities and influence in other areas of the foot. MATERIAL AND METHODS 32 people participated through non-probability convenience sampling in a quasi-experimental study in which self-reported data were recorded, the determination of plantar pressure, and body weight distribution. RESULTS 64 feet were studied, showing no difference between the medium pressure and the forefoot without orthoses of 5 mm and 10 mm. Decrease in average pressure and percentage of body weight, both statistically significant, with hindfoot orthoses 10 mm was observed. CONCLUSIONS Given the current evidence for the prescribing and use of foot orthoses is limited, designed to improve the functionality and prevent the onset of disease and foot deformities, these results highlight the need to prescribe orthotics 10 mm when needed to relieve pressure on the backfoot, not seeing the average pressure increased nor diminished in other areas of the foot.
