Summary

Forefoot varus is a type of foot deformities. It is asociate with subtalar joint hyperpronation, and cause too much stress over tissues around foot and lower leg during weight bearing activities.

One of the common interventions for forefoot varus is to use foot orthosis with medial forefoot wedge to accommodate the forefoot deformity. Forefoot varus has been considered as an osseus deformity and caused by insufficient talar torsion during development. However, recent studies have reported forefoot varus may not be an osseus deformity. They might be a result of soft tissue adaption. For example, subtalar joint hyperpronation and ankle equinus could lead to forefoot supination/compensatory forefoot varus, which could be mistaken for osseus forefoot varus after a long period of time. If compensatory forefoot varus is caused by soft tissue adaptions, these adaptions may have a chance to reverse.

Nowadays, orthoses which applying medial forefoot wedge to accommodate the deformity for forefoot varus deformity, and the other type orthoses which applying rearfoot medial wedge and arch support are both used in subject with forefoot varus deformity.

However, some colleges claims that using medial forefoot wedge to accommodate the deformity of forefoot varus, the deformity may be fixed after a long-term period. However, there were no studies compare the effect of arch support orthosis that with and without medial forefoot wedge.

Conditions

  • Forefoot Varus
  • Flat Feet

Interventions

OTHER

Arch support orthoses with forefoot medial wedge

The degree of forefoot wedge will be 3 degree. If needed, it could be adjusted. The subjects need to wear the orthoses for at least 30 hour per week during the experiment.

OTHER

Arch support orthoses

The arch support of the orthoses could be adjusted depends on the evaluation of subject. The subjects need to wear the orthoses for at least 30 hour per week during the experiment.

OTHER

Flat insole

The flat insole used as a placebo intervention. The shape of this insole is flat, and made by soft EVA. It only provide shock absorbtion without any support. The subjects need to wear the orthoses for at least 30 hour per week during the experiment.
