Although custom-made foot orthotics are commonly prescribed to relieve lower limb injuries, few studies have documented their effects on the biomechanics of locomotion. The objective of this project was to quantify the effect of orthotic wear on kinematic, kinetic and electromyographic characteristics of the legs during walking and running. Fourteen subjects with custom-made foot orthotics were asked to run and walk over a 10-m walkway. Kinematic, kinetic and electromyographical parameters were recorded during all trials. One-way repeated measures ANOVA and paired students t-tests were used to evaluate the effect of orthotic wear as well as foot type (flat, normal). With orthotic wear, the activity of the soleus muscle was decreased for both groups of subjects with and without flat feet during running. The effect of orthotic wear on all other parameters was not significant. More in-depth studies are needed to generalize these results on the overall population of orthotic wearers.
