2. First Ray Facilitation

 

 

FDI standard orthotics incorporate a first ray recess. The first ray consists of the first metatarsal and the medial cuneiform.

 

The functional implications of incorporating a first ray recess into the orthotic design are as follows:

  • Encourages sagittal plane motion by allowing the first ray to plantar flex in gait, thereby assisting the initiation of the windlass mechanism. This will relieve tensile stress of the plantar fascia and promote shock absorption during loading at the forefoot.

  • Promotes stability during the propulsive phase of gait.

  • Provides a better overall relationship for the biomechanics of the lower limb and foot.
