A method for selecting size of an orthotic for a foot is described, where the method comprises collecting certain measurements for a foot, such as a length l.sub.1 corresponding to a distance from a proximal point of the heel to a base of a metatarsal head and, optionally, a width w corresponding to a distance from the medial edge of the foot at approximately the base of the first metatarsal head to the lateral edge of the foot at approximately the base of the fifth metatarsal head, and, optionally, a height h corresponding to the height of the lateral foot arch relative to ground. The height h is measured, in some cases, with the foot in an adjusted or restored condition. The measurements are used to recommend or to select a size of an orthotic product.

The invention relates to devices and methods for designing and manufacturing customized footwear, and components thereof. An example method includes a method of designing at least a portion of a sole of an article of footwear customized for a user. The method includes the steps of determining at least one input parameter related to a user, analyzing the at least one input parameter to determine at least one performance metric of a foot of the user, and determining at least one customized structural characteristic of at least a portion of a sole of an article of footwear for the user based on the performance metric.

Embodiments of the present disclosure relate to a scanning device comprising a support base, a calibration pattern disposed on an upper surface of the support base, and a plurality of cameras distributed around an outer perimeter of the support base. In at least one embodiment, the calibration pattern is undetectable or substantially undetectable to the human eye.

An electronic measurement system for human foot length and width and a human health monitoring device. The system monitors the capacitance change values generated by the multiple touch points in contact with the subject's foot sole, and measures the subject's foot length and width based on the capacitance change values and the distribution positions of the touched points. The subject's foot length and width can be measured through the capacitance change region and values caused by the contact of the human foot with the multiple touch points. The measured results no longer have large measurement errors due to personal measurement method habits or inconsistent foot placement during children's measurements, etc., thereby significantly improving measurement accuracy and reducing costs.

One or more embodiments of the invention are a novel wearable device assembly that help in early detection of plantar fasciitis and improve mobility. Particularly, the present invention relates to a wearable sensor assembly which detects calcaneal inclination (pitch) angle using flex sensor that determines risk factor of plantar fasciitis. This invention functions by measuring the calcaneal pitch angle of patient's foot and comparing that with the normal calcaneal pitch angle established for normal foot. The risk factor of plantar fasciitis is predicted as calcaneal pitch angle of the foot is significantly lower in patients with plantar fasciitis than in normal subjects. With an early diagnosis of plantar fasciitis, patients can receive early treatment leading to improved mobility and better quality of life. This wearable sensor can work wirelessly and enable real-time data collection from the patients to assist medical professionals during the detection and treatment of plantar fasciitis.

A method and computer program product, the method comprising: obtaining a 3D computerized foot model of a foot of a patient; displaying the 3D computerized foot model over a display device; receiving from a user locations of a first set of model points on the 3D computerized foot model, each model point of the first set associated with predetermined anatomical features; automatically adapting a base shell 3D model upon the first set of model points to obtain an adapted shell model; automatically calculating an additional set of model points based on the first set of model points, the first set and the additional set of model points representing a shape of a foot arch of the patient; and automatically enhancing the adapted shell model upon the first set of model points and the additional set of model me points to obtain an orthosis deign for the foot.

A method for determining foot dimension data includes: receiving a top-view foot image and a hindfoot image; obtaining first position data and second position data; obtaining a first foot contour in the top-view foot image; obtaining a second foot contour in the hindfoot image; determining an anterior reference point on the first foot contour; determining a posterior reference point on the second foot contour; adjusting the second foot contour to obtain an adjusted foot contour that has an adjusted posterior reference point; superimposing the adjusted foot contour on the first foot contour; obtaining a first straight line; obtaining a lateral point and a medial point; and determining the foot dimension data of the foot at least based on the lateral point, the medial point and the adjusted posterior reference point.

An example apparatus for measuring human body parts includes a touchscreen display to detect touch capacitance information associated with a body part. The apparatus also includes a processor to determine a size of the body part based on the detected touch capacitance information.
