The first ray measuring device (FMRD) was designed to correct this problem by allowing for more precise evaluation of the static and dynamic function of the first ray.
  • In addition to measuring dorsi-plantar motion, the FRMD also allows for precise evaluation of the static position of the first metatarsal head.
