Will the Dobbs Bar result in equinus problems if used with regular shoes?
No, this is a myth. There is no data to support such a claim. The advantage of the dynamic bar is that children can actually use their muscles more both at the knee as well as the ankle promoting increased motion in general. In addition, setting the shoes in external rotation on the bar, which is required for maintaining clubfoot correction, actually promotes ankle dorsiflexion and not equinus.
