Abstract:
1. An orthotic device for controlling motion of a human foot in a functionally corrected anatomical position from heel strike through toe off, the orthotic device comprising: a rearfoot region including rearfoot medial and lateral wedges, the rearfoot medial and lateral wedges intersecting at an expected contact location of a medial side of a midline of a heel of the human foot on the rearfoot region of the orthotic device; a midfoot region including midfoot medial and lateral wedges, the midfoot medial and lateral wedges intersecting inclusively between expected contact locations of a first cuneiform bone and a cuboid bone on the midfoot region of the orthotic device; a forefoot region including forefoot medial and lateral wedges, the forefoot medial and lateral wedges intersecting inclusively between expected contact locations of first and fifth metatarsal bones on the forefoot region of the orthotic device; a toe region including toe medial and lateral wedges, the toe medial and lateral wedges intersecting inclusively between expected contact locations of first and fifth toes on the toe region of the orthotic device; and a support, defined by a contour of the forefoot medial wedge, extending from an intersection of the forefoot medial wedge and forefoot lateral wedge beginning at an expected contact location of a second metatarsal head and neck area, the support projecting inclusively between fore and aft joints of the first metatarsal bone at an angle determined as a function of a degree of plantar-flexion of the first metatarsal bone, the angle referred to as a plantar flexion angle and defined as a function of a difference between angles in a z-direction of first and fifth and second and fifth metatarsal heads, the medial and lateral wedges being defined in a coronal plane, the medial and lateral wedges having corresponding medial and lateral angles greater than zero in the coronal plane, the medial and lateral wedges having corresponding edges distal from the respective intersections and wherein the wedges increase in height from their edges toward the respective intersections.
