Abstract: An orthotic device for insertion into a high-heeled shoe is provided. An orthotic device made in accordance with the instant invention virtually eliminates the problems associated with the wearing of high-heeled shoes, particularly pronation effects, general foot discomfort, posture problems, toe pain, and arch pain. The orthotic device comprises a right or semi-rigid shell for positioning beneath the heel of the foot and extending forwardly towards the toes of the foot. The shell terminates behind the five metatarsal heads of the foot, and is shaped whereby to permit the first metatarsal head freely to evert and plantarflex under load, and is shaped such that the heel of the foot is carried substantially parallel to or slightly backwardly inclined relative to the ground plane.

Abstract: A foot orthosis for correctably realigning and repositioning specific anatomic segments of the human foot consists of three functional components, namely, a heel complex segment and two longitudinal forefoot segments--namely, a medial segment and a lateral segment.The heel complex segment is independently connected to each longitudinal forefoot segment by a connector. The segments function sufficiently independently from one another to consider the device a triplanar foot orthosis.

Abstract: The flexible force sensor having an electrical conductor releasably attachable to a test site and a plurality of relatively spaced electrical contacts supported for varying contact with the conductor such that when a force is applied to the force sensor, the electrical contacts and electrical conductor move into and out of varying areas and/or paths of electrical contact to produce electrical resistances therebetween corresponding to the extent of such areas and/or paths and as a function of the applied force.

Abstract: An orthotic device that includes a boot for immobilizing the ankle and foot against relative movement and holds them in a neutral position of maximal joint congruency while providing a sole having a platform for causing the foot to describe a heel to toe rocking movement such that the leg of the user is flexed at the knee and a pivotting motion is induced at the hip joint during walking.
