Background and aim: Flexible flat foot is a common deformity in lower extremity, the foot arch collapses and the ground reaction forces does not apply properly to the foot. Backward walking is a common rehabilitive technique and is utilized to improve strength and balance. The purpose of this present study is to compare the salient points vertical ground reaction force measurements in flat foot patients while walking forward and backward with those of healthy subjects using a force plate system.
Materials and methods: 10 flexible falt foot female subjects  and 10 healthy female  subjects were  recruited to participate in this study. Each Subject walked 5 times forward and 5 times backward and the vertical ground reaction force was measured by a force platform.
Results: The results of this present study suggest a significant difference in kinetic pattern of forward walking compared to backward walking in both healthy and flexible flat foot participants. The force related to first peak of vertical ground reaction force was significantly less in forward walking compared to backward walking (p=0.000). Whereas the force related to trough and second peak of vertical ground reaction force were significantly high in forward walking compared to backward walking (p=0.000).
Conclusion: The results of this study show that backward walking changes the ground reaction force compared to forward walking and the main characteristic of this difference is due to decrease of forces applied to the heel of foot which may be important in flat foot patients.

Keywords: Backward walking and forward walking, Flexible flat foot, Ground reaction force
