Which condition is a contraindication for using a DAFO?

A solid understanding of the use of Dynamic Ankle Foot Orthoses (DAFO) can clarify why a rigid foot presents a contraindication for this type of orthotic device.

DAFOs are specifically designed to accommodate and support flexible foot and ankle deformities while allowing for movement and function. They provide a dynamic response to the foot's natural mechanics, which is beneficial for conditions where there is some degree of flexibility in the foot structure. In contrast, a rigid foot does not allow for any mobility or movement within the orthosis. This lack of movement means that the DAFO would not serve its intended function of enhancing mobility and support; rather, it could restrict movement further or cause discomfort.

The other mentioned conditions—flexible pes planus, spastic diplegia, and hypotonic cerebral palsy—typically involve some flexibility or movement potential in the foot and ankle, allowing DAFOs to improve function, enhance stability, or provide the necessary support while facilitating the natural gait mechanics. Flexible pes planus, for instance, may benefit from a DAFO’s support during ambulation. Similarly, in cases of spastic diplegia and hypotonic cerebral palsy, the use of a DAFO can help manage muscle tone and provide the
