The Functional Foot Orthosis

Part 1 Clinical measurements: how this decision is made; translation of clinical measurements into posting angles. Part 2 Choice of material: shell of the orthosis; "post" of the orthosis; how the choice of material is made. Part 3 Negative cast creation and assessment: plaster of Paris bandage; the cast; techniques used to obtain a "negative" slipper cast of the foot with the sub-talar joint in its neutral position; assessment of the negative cast. Part 4 Creation of a "positive" casted model of a foot: plaster of Paris; obtaining the positive cast from a negative cast. Part 5 Production and modification of a positive cast: plaster addition. Part 6 Materials used: thermoplastics; covering materials; general principles of working with thermoplastics. Part 7 Manufacture of rigid and semi-flexible orthoses: shell of the orthosis; contact adhesive; posting; covering the orthosis. Part 8 Ethylene vinyl acetate (EVA) orthoses: the all-in-one orthosis. Part 9 Adaptations of the EVA orthoses. Part 10 Intrinsic posting: points to consider when deciding whether to use intrinsic posts; intrinsic posting technique. Part 11 Unusual shapes for shells of orthoses: abduction of the foot distal to the mid-tarsal joint; abduction of the foot distal to the mid-tarsal joint; severe pes cavus, severe arthritic disease of the ankle and sub-talar joints, and all conditions which have resulted in a gravitational foot drop; in-toeing and out-toeing gait patterns. Part 12 The issuing and "wearing-in" of orthoses: rigid and semi-flexible orthoses; accommodative orthoses; the wearing of orthoses for sport. Part 13 Common problems.
