Abstract

Background and Aims: Several therapy techniques have been recommended to enhance the running mechanics of individuals with flat feet. Less emphasis has been paid to the impact of these therapeutic treatments on the ground reaction forces (GRF) and the center of pressure (COP). Nevertheless, these kinetic effects play an important role in identifying possible injuries and the body's compensatory mechanisms in response to any therapeutic approach. The aim of the present study was to compare of the effects of foot orthoses and anti-pronation taping on COP and GRF during flat feet running.
Materials and Methods: A randomized cross-over study design was used in the present study. kinematic and kinetic data of 20 young people with flexible flat feet were measured during running in three conditions: 1- Athletic shoes, 2- Athletic shoes and foot orthoses 3- Athletic shoes and Low Dye tape. One way repeated measure ANOVA method was used to find the significance differences in GRF and COP time series between different conditions (SPM1d software package).
Results: The results showed that foot orthoses reduce the anteroposterior GRF compared to relative Low Dye tape, and increases the lateral GRF compared to shoes without intervention (P<0/05); but the conditions did not have a significant effect on the vertical GRF. Moreover, the use of FO-shoes and tape-shoes has caused medial and lateral shifts in COP, respectively (P<0/05).
Conclusion: The medical insole may cause inefficient force transmission in the anterior direction. Furthermore, running in FO-shoes and Tape-shoes have substantial influences on COP displacements towards the end of the stance phase; however, since minimal load and forces are applied to the joint at that time, it does not appear to increase running-related injuries.
