Prosthetic liner formed of a molded silicone elastomer material including an inner wall, a circular outer wall having radii of curvature centered along a first longitudinal axis of external symmetry extending longitudinally centrally within the liner, the inner wall including a circular curved inside anterior wall portion extending along a liner length and having first radii of curvature centered on a second longitudinal axis of anterior curvature extending longitudinally along the liner length and a circular curved inside posterior wall portion having a second radii of curvature centered on a third longitudinal axis of posterior curvature extending along said liner length. The first, second and third longitudinal axes lie in a common longitudinally and transversely extending plane bisecting the anterior and posterior wall portions, and the second and third axes are spaced apart a predetermined offset distance on opposed sides of the first axis to thereby define an anterior wall portion that is thicker along the liner length than the posterior portion.

An ambulation assistance device is provided with a leg support that releasably secures to an individual's leg and supports the leg in a positively flexed position. An elongated pylon extends downwardly from the leg support and may be hinged at the point of connection to simulate the mechanics of the individual's knee during ambulation. A resilient rearward brace may be used to bias the pylon toward a standing position. A forward brace may be provided to limit over extension of the pylon. A foot member may be pivotably coupled with the distal end of the pylon to simulate the mechanics of the individual's ankle during ambulation.

An ankle splint product includes an ankle splint for being custom-formed to the shape of an ankle while flexible and upon hardening providing a rigid, supporting custom fit. The ankle splint product includes an outer container formed of moisture-impervious material, and first and second flexible ankle splint segments positioned in the container in substantially moisture-free conditions and sealed therein against entry of moisture until use. Each of the first and second ankle splint segments includes an elongate substrate and a reactive system impregnated into or coated onto the substrate. The system remains stable when maintained in substantially moisture-free conditions and hardens upon exposure to moisture to form a rigid, self supporting structure. An elongate, flexible protective pad is positioned on one side of the substrate along its length to provide a cushioning barrier between the substrate and the skin of a patient when the ankle splint is in use. An elongate outer cover covers the substrate on the side opposite the protective pad. A flexible cushion insert has a first major surface overlying the protective pad and an opposing second major surface adapted for residing adjacent an ankle bone of the patient. The cushion insert cooperates with the protective pad to further protect and cushion the ankle of the patient when the ankle splint is in use.

A method of differentially tuning a lower limb muscle in a human in need thereof is provided. The method includes placement of at least two calibrated, differential disturbances or protuberances under the human's feet thereby tuning a lower limb muscle.

A prosthetic limb has an outer surface that is a mirror image of an intact limb. The intact limb is scanned and the surface data is manipulated to create a virtual mirror image. The end of the amputated limb is also scanned to obtain socket data. A virtual limb is designed using a computer program based upon the mirror image and end of the amputated limb data. The computer program is also used to design a removable fairing that provides color and texture to the prosthetic limb.

The invention discloses an implementation method for identifying motion models based on cerebral-cortex hemoglobin information. A testee self-controls the starting and stopping time under four motion models; as for the change rate of cerebral-cortex hemoglobin concentration, the statistical analysis technique is adopted to analyze the statistical difference between oxyhaemoglobin and deoxyhemoglobin in various motion related areas of the cerebral cortex under different motion models, and based on the statistical characteristics, two relative motion trends of getting-up and sitting-down, as well as stair ascending and descending, are distinguished; and on this basis, the difference between oxyhaemoglobin and deoxyhemoglobin in various motion areas of the cerebral cortex is analyzed, together with the both-leg relative motion trends and the new statistical characteristics, the specific motion model is distinguished. The non-intrusive NIRS technology is adopted to record the cerebral-cortex hemoglobin concentration information of a human body without external stimulation or preliminary training, and restrictions on the test environment and the testee are less; the advantage of ideal time and space resolution is achieved; and the intelligence of walking aids is improved.
