A system for determining the alignment measurement of the foot and ankle is disclosed. The system uses data representative of a three dimensional scanned image of a patient's foot and ankle while the patient was applying weight on the foot. Next the system detects the three dimensional coordinates associated with at least three predetermined landmarks on the patent's foot in the scanned image. A ground plane is determined using the predetermined landmarks. A center of a talar dome is determined in the scanned data. An ankle offset lever arm id determined from the set of landmarks and center of the talar dome.

The outerwear is additively manufactured using a three-dimensional (3D) printer to provide for dynamic configurations of the sensors, actuators and other electronics depending on the specific needs of an individual. In addition to sensors for tracking motion, resistance, temperature and temporal features, the actuators may include piezoelectric components and microfluidic components to provide for therapeutic treatments, medical treatments and accident avoidance features. The combination of sensors and other electronics may also provide applications for monitoring overall health and growth.

A system has a body with a base having a top surface with a receiving region to receive the bottom of a single foot. Among other things, the base may be in the form of an open or closed platform with a plurality of temperature sensors in communication with the top surface of the receiving region. The plurality of temperature sensors are within the receiving region and configured to activate after receipt of a stimulus applied to one or both the platform and the plurality of temperature sensors. A comparator is configured to form a temperature range as a function of the temperature value distribution and compare a percentage of the range size of the temperature distribution to a threshold value. An output produces ulcer information indicating the emergence of an ulcer or pre-ulcer when the percentage of the range size equals or exceeds the threshold value.

A system, method, and computer readable medium for measuring limb range of motion. The method includes initializing a scanning area. A classifier trained to recognize limbs is loaded into memory. A frame representing a 3D point cloud having at least one limb of a person in motion is captured. A box fitting algorithm is performed on the captured at least one limb to enable the classifier to identify the at least one limb. One or more boxes generated from the box fitting algorithm are sliced into a plurality of 2D point clouds to measure and record the circumference of each 2D point cloud to obtain limb range of motion parameters. The limb range of motion parameters are a maximum and a minimum size of the at least one limb as a function of soft tissue expansion and contraction of the limb while under pressure, force, and/or motion.

A compression sock used in a foot measuring system, and worn on a user's foot that has a metatarsophalangeal joint area. The compression sock includes a sock cuff end, and a sock body. The sock cuff end is for insertion by the user's foot. The sock body is connected to the sock cuff end, and includes a high compression zone that surrounds the metatarsophalangeal joint area, and a standard compression zone that is proximate to the sock cuff end. A compression pressure value exerted by the high compression zone of the sock body on the metatarsophalangeal joint area is higher than a compression pressure value exerted by the standard compression zone on the rest of the user's foot.

A foot structure and function assessment device and a method of using the device are provided. The device includes a base having a top surface for supporting a patient's foot, a clamp attached to the base for immobilizing a second metatarsal of the foot, a vertical measurement mechanism carried by the base for measuring displacement of a first ray of the foot, an actuation member for vertically displacing the first ray, and a controller configured to displace the first ray by applying a first vertical load to the first ray using the actuation member, wherein the first vertical load is associated with a first ray position of the foot, and to displace the first ray by applying a second vertical load to the first ray using the actuation member, wherein the second vertical load is associated with a first ray mobility of the foot.

A device for recording physiological information includes a carrier board comprising a plurality of force transducers and a plurality of contact sensing elements; and a processing unit, coupled to the force transducers and the contact sensing elements, configured to determine a center of gravity (COG) according to outputs of the force transducers, configured to determine a contacted range according to outputs of the plurality of contact sensing elements, configured to record the center of gravity and the contacted range, wherein the gravity and the contacted range substantially correspond to the same time point.

A custom foot orthotic and a system and a method for designing of a custom foot orthotic. The method includes: receiving 3D scan data of the patient's foot; receiving plantar pressure scan data of the patient's foot; establishing a desirable pressure distribution; generating an underfoot elevation profile relative to an elevation profile of the patient's foot in the 3D scan data; determining an internal density profile of the resulting foot orthotic 3D model by superimposing the desirable pressure distribution over the resulting foot orthotic 3D model and reducing or increasing density in regions of the foot orthotic 3D model based on the difference between an expected pattern of support and the desirable pressure distribution; and outputting the 3D model of the custom foot orthotic.

Systems and methods of measuring feet and designing and creating orthopedic inserts are described. A leg length discrepancy of a user is measured and this data, along with foot size are input into a computer. The computer then creates a computer model of a custom shoe insert based on this information. The computer model is then sent to a 3D printer to print the insert. The insert consists of a base insert with partial correction, and several additional layers that are added successively over time until a full correction is obtained. This eliminates any pain associated with a fully corrective insert, and allows the body to adjust gradually to the correction.

A method and apparatus is provided for measuring human feet shape. Method and apparatus are designed to be effective for large scale measurement of feet, for example in shoe stores. Measurement is very fast, reliable, accurate, convenient for end consumer and easy to use either in self-service or by a trained operator. Apparatus involves usage of either one or multiple depth sensors, which capture part of the foot shape or whole foot surface, depending on the setup. Depth sensors are capable of capturing an image with depth information, which results in a three-dimensional point cloud from each sensor. Apparatus may be combined with a pressure plate, which provides complementary information on end-consumers feet and the gait behavior. The innovation provides a solution for many commercial/noncommercial applications, such as shoe retail business (matching the foot to particular footwear), biometrical research (examining the distribution of feet properties within particular population), clinical examination, etc.
