A link extends between a distal member and a proximal member of a wearable device, such as an exoskeleton, orthosis or prosthesis for a human lower limb. One or other of the distal member and the proximal member includes a crossing member. The link extends from the crossing member of the distal member or the proximal member, to the other of the distal member or the proximal member. Actuation of the link translates to a force at the distal or proximal member that is normal to a major longitudinal axis extending through the distal and proximal members. In one embodiment, a sliding link of a device configured for use with a human joint tracks two degrees of freedom of the joint.

A dental orthotic comprises a mandibular orthotic conforming to a user's mandibular dentition and including oral contours adapted for adjusting the user's tongue/tooth/mouth interaction, and may include extensions for positioning the user's tongue. The contours are designed and applied to specific locations on the orthotic and extensions of the orthotic to promote a desired tongue response for specific physiological symptoms. The contours change the shape of the mandibular orthotic as well as the dental shapes within the mouth, resulting in repositioning and/or reshaping of the tongue and tissue of the throat, thereby improving the oral functions as well as relieving neuromuscular responses and autonomic nervous system dysfunctions. The dental orthotic may include a maxillary orthotic that is fixed with respect to the mandibular orthotic.

A method and apparatus for providing a topographical map of the bottom of a patient's rear foot with the foot in a semi-weight bearing condition and in the neutral position. A flexible membrane defines the top of an air cushion that captures the patient's foot in the neutral position when the air pillow is inflated. The membrane also conforms to the bottom of the foot. A three-dimensional scanner located below the membrane measures the distances to the bottom of the membrane over an array of positions. A manufacturing facility converts these measurements into information by which computer numerical controlled equipment machines an orthotic insert for the patient's footwear.

An improved athletic shoe, ankle orthosis and method for protecting the ankle against injury, limit subtalar joint motion of the ankle by controlling the motions of segments of the subtalar joint fore and aft of the subtalar joint while permitting motion of the foot about the ankle joint. A supporting structure a part of or connected to the shoe or orthosis is preferably in the form of a heel-sole counter provided about the heel and at least a portion of the foot forward of the subtalar joint. The supporting structure has a semi-rigid shape retaining character which is not collapsible vertically and which together with the shoe or orthosis limits torsional movement of the foot about the longitudinal axis of the subtalar joint as seen in a top plan view thereof by an upwardly extending portion thereof which acts as a torsion bar that is, in turn, secured to the lower leg. Preferably, the torsion bar has directional properties for resisting bending which are most rigid in a direction orthogonal or nearly orthogonal to the longitudinal axis of the subtalar joint. In a disclosed embodiment of the shoe motion of the midtarsal joint is also limited by the supporting structure to aid in limiting subtalar joint motion and shoe rollover. The shoe is secured to the foot by way of a strap arrangement which applies a force to the foot in a direction which, together with the heel-sole counter opposes the subtalar joint motion in supination.

A knee orthosis is provided having upper and lower arms and a hinge assembly positionable about the knee to one side of the patella. The hinge assembly has a hinge pivot and a tension strap lever. The upper and lower arms and tension strap lever are each rotatable about the hinge pivot. A compression member is positioned in engagement with the knee on the opposite side of the patella from the hinge assembly and a tension strap is connected to the compression member and the tension strap lever. The tension strap applies a tension force to the compression member which increases when the upper and lower arms and tension strap lever rotationally transition from a flexion position to an extension position and decreases when the upper and lower arms and tension strap lever rotationally transition from the extension position to the flexion position.

A hip orthosis includes a hip engaging unit that can be secured to the contours of a human hip. An appendant orthotic member is formed to extend diagonally about and to be fixed to a human appendage. A connector assembly, with a support plate with a curved configuration at an anchor location to permit adjustment, interconnects the hip engaging member and the appendant member and includes an articulated joint member to control flexion, extension, abduction and adduction. The joint members can include an adjustable linkage system extending across and connected to both sides of the articulated joint. A first link member can be adjusted in length to control the movement of the articulated joint. An adjustable hinge member having a rotational axis which is offset by approximately 90° from a rotational axis of the articulate joint can be set to limit a range of flexion, while movement of the articulated joint provides either a controlled abduction or adduction movement Alternatively, the articulated joint can be formed by a roller and cam arrangement.

Measurements for corrective footwear, orthopedics, and orthotics have traditionally been obtained through three-dimensional casts of a foot. Digital technology opens an avenue of utilizing a digital image in place of the cast. Using a single or dual flatbed scanner and a computer, all the data required to construct a corrective device may be obtained from a scan or scans of the foot. Observed features and color variations, as well as physical measurements are used to overcome imperfections of a patient's foot.
