Foot orthosis uses as conservative treatment in subjects with flatfoot. This study aimed at assessing the effects of Foot orthosis on Energy consumption in 20 runner subjects with Flat foot. In this study treadmill and Quark b2 oxygen consumption device were used. In the first stage patients did not wear Foot orthoses. Then in the second stage for each patient prepared a pair of suitable foot orthosis and they wore orthoses. The maximum running Heart rate, vo2 max and vo2 of the patients with Flat foot were measured and calculated with and without Foot orthoses. statistical analysis indicated significantly less HR, VO2, VO2 max in before and after use of foot orthoses on runners with flat foot. (P-Value <0.05). Foot orthoses result in realignment of lower extremity Joints in patient with flat foot, thus length-Tension Relationship of muscles improves. this prevent of fatigue on this muscles, when he run in long- distance. Finally, when suitable Foot orthoses was applied energy consumption during running decreased.
