A foot orthotic having a body adapted to support a foot of a user is disclosed. The foot orthotic has a stiffness adjusting member (6) adapted to be mounted to the body to adjust the stiffness of the orthotic. Protrusions on the body enable the stiffness adjusting member (6) to be mounted to the body.

A training device for stimulating nerve cell ends in a training manner, includes a housing having at least one first housing portion and a plurality of stimulators or stimulating physionomie-typical nerve area portions. A plurality of stimulators are arranged systematically at least on the first housing portion of the housing so that the plurality of stimulators in the training state each act on nerve cell ends with which they are associated. Also disclosed are a method for operating the training device, the use of the training device as a modular stimulation device for stimulating nerve cell ends, a prosthesis, a method for producing a prosthesis and the use of a training device for stimulating nerve cell ends in a prosthesis.

Composite materials with certain functional or securement parameters are provided herein. Layered composite prosthetic with spring layers and composite rivets are provided. Fiber reinforced layers are grouped into keel, sole plate or other component and these components are configured to provide a spring action for the prosthetic alone or in combination. One or more composite rivets are installed to secure components together.

Blade-type prosthesis assemblies include a socket securable to a wearer of the prosthesis assembly and a blade securable to the socket. The blade has a blade body extending between a blade bottom and a blade top. The assembly further includes a base plate securable to the blade bottom. The base plate includes a shroud retainer element. The assembly further comprises a blade shroud covering at least a portion of the blade body and securable to the shroud retainer element and at least one of the socket and the blade body.

The present foot prosthesis includes various structural features that provide the foot with advantageous rollover properties. In certain embodiments, the foot guides rollover toward the medial side. For example, an asymmetrical upper element and a correspondingly shaped resilient ankle member support more of the wearer's weight on the lateral side as the foot rolls over. In another embodiment, stiffeners added to the resilient ankle member increase the stiffness on the lateral side relative to the medial side. In certain other embodiments, the foot provides progressively increasing support from mid stance through toe off. For example, a gap between the resilient ankle member and the lower element closes during the later portion of the wearer's gait. The closing gap increases a contact area between the resilient ankle member and the lower element, providing progressively increasing support. In another embodiment, the foot includes a gap between a lower front edge of an attachment adapter and the upper element. The gap may be filled with a resilient material.

The invention relates to a method for producing an artificial foot, comprising a medial plane (M) in a longitudinal axis, in which a nominal foot length (1) is defined as a distance from a heel to a foot tip of a natural foot replaced by the artificial foot, and designed having a top side connecting piece (4) for torsionally rigidly connecting a foot insert (2) extending substantially over the length of the foot (1), and contacting two contact surfaces (6, 7) over the length (1), of which a first heel side contact surface (7) is located in the heel area and a second hall side contact surface (6) is located in the hall area, and designed so that the connecting part (4) is connected to the contact surfaces (6,7) of the foot part by means of spring connections.

A prosthetic foot with a structural component having a proximal attachment member for fastening the prosthetic foot to a below-knee tube, a below-knee shaft or a prosthetic knee joint, with a forefoot portion secured or formed on the structural component, and with a heel-side spring-damper system which is assigned to the structural component and which is compressed at a heel strike and bears on a sole-side guide element. The structural component is designed as a leaf spring which extends in a posterior direction from the proximal attachment means, and forms an arch and is guided in an anterior and distal direction, wherein the arch protrudes posteriorly beyond the guide element.

A prosthetic foot is provided with a forefoot spring, a heel spring and a base spring. The base spring is connected to the heel spring and to the forefoot spring. The base spring has receiving means for the forefoot spring and the heel spring, into which receiving means the heel spring and the forefoot spring can be inserted. The heel spring is connected to the forefoot spring via a coupling element, and the coupling element extends forwards along the forefoot spring at least via one portion thereof.

A prosthetic foot includes a base spring, a top spring assembly, a connector assembly, and a heel cushion. The top spring assembly includes first and second spring members, and first and second bond connections. The second spring member extends parallel with and spaced apart from the first spring member. The first bond connection is between distal ends of the first and second spring members, and the second bond connection is between a distal end of the second spring member and a top surface of the base spring. The top spring assembly has a first portion arranged horizontally, and a second portion arranged vertically. The connector is connected to a proximal end of the top spring assembly to connect the prosthetic foot to a lower limb prosthesis. The heel cushion is mounted to the base spring at a location spaced forward of a heel end of the base spring.

A prosthetic foot plate can have adjustable flexibility in the toe region, the metatarsal area, and/or the arch to accommodate different heights to which a heel region of the prosthetic foot plate is raised. The adjustable flexibility can be provided by materials of different stiffness and/or different physical structures of one or more locations on the prosthetic foot plate. In another variation, the adjustability in the toe region can be provided by a link between the toe region and ankle of the prosthetic foot. The link can be actuated to adjust an orientation of the toe region and/or the metatarsal region in any heel-height setting.
