## Abstract

An apparatus comprised of a plurality of engagement structures independently movable along a longitudinal axis to initially engage a mid-foot region of a foot is described. A center structure or a first set of engagement structures engage the foot in a mid-foot region, and one or more peripheral engagement structures engage the plantar surface in regions surrounding the mid-foot region independent from the structure(s) engaging the mid-foot region. Positional information about the engagement structures is obtained, and a surface map from the positional information is constructed, to determine a profile or contour for an orthotic device in which the foot is in a restored bone state.

## Claims

### Claim 1

An apparatus, comprising:
a plurality of pins, each pin independently movable along a longitudinal axis, and
one or more biasing members configured to exert a force on one or more pins in said plurality of pins, such that a first set of pins in said plurality of pins is moved from a first position to a second position independent of a second set of pins in said plurality of pins, wherein said first set of pins is within an inner region of the plurality of pins and said second set of pins is peripheral to the first set of pins.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein pins in the first set of pins are moved prior to movement of pins in the second set of pins.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein pins in the first set of pins are moved by a first force applied by a biasing member in the one or more biasing members to the pins in the first set of pins, the first force different from a second force applied by a biasing member in the one or more biasing members to pins in the second set of pins.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the one or more biasing members comprise at least two biasing members.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein a first biasing member is dedicated to achieve movement of the first set of pins and a second biasing member is dedicated to achieve movement of the second set of pins.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein said one or more biasing members is configured for contact with a third set of pins in said plurality of pins such that pins in the third set move along their longitudinal axis independent from movement of pins in said first set of pins or said second set of pins.

### Claim 7 (depends on 10)

The apparatus of claim 10, wherein the third set of pins are subsequent to movement of pins in the first set of pins or wherein the third set of pins are moved by a pressure applied to the third set of pins that is different from a pressure applied to the first set of pins.

### Claim 8 (depends on 1)

A method for obtaining a restored bone state in a foot, comprising:
placing a plantar surface of a foot on an apparatus according to claim 1, the plantar surface placed on an upper surface defined by the plurality of pins, wherein said plurality of pins are in an initial position;
causing movement of pins in the plurality of pins via the one or more biasing members, such that at least a first set of pins adjusts one or more bones in the foot to a restored bone state and a second set of pins additionally engages the foot plantar surface; and
determining a position of each pin in at least the first pin set and the second pin set to obtain a profile of the foot in its restored bone state.

### Claim 9 (depends on 8)

The method of claim 8, wherein causing comprises causing the first set of pins and the second set of pins to engage the foot plantar surface to adjust one or more bones to a restored bone state.

### Claim 10 (depends on 8)

The method of claim 8, wherein causing comprises causing the first set of pins to engage the foot plantar surface to adjust one or more bones to a restored bone state prior to engaging the second set of pins with the foot plantar surface.

### Claim 11 (depends on 8)

The method of claim 8, wherein said causing further comprises causing the first set of pins to adjust one or more bones in the mid-foot region of the foot, and causing a third net of pins in the plurality of pins to move via the one or more biasing members, such that pins in the third set of pins engage the foot plantar surface at a region other than the mid-foot region.

### Claim 12

A method, comprising:
placing a plantar surface of a foot an apparatus comprising (i) a plurality of pins, wherein each pin in the plurality of pins is independently movable along a longitudinal axis, and (ii) one or more biasing members configured for contact with one or more pins in said plurality of pins, such that a first set of pins in said plurality of pins is moved along the longitudinal axis of each pin in the first set independent of a second set of pins in said plurality of pins, wherein said first set of pins is within an inner region of the plurality of pins and said second set of pins is peripheral to the first set of;
causing movement of the one or more biasing members such that at least some of the pins in the plurality adjust one or more bones in the foot to an adjusted position; and
determining a position of each pin in at least the first pin set and the second pin set.

### Claim 13 (depends on 12)

The method of claim 12, wherein causing comprises causing movement such that the first set of pins adjusts one or more mid-foot bones to an adjusted position.

### Claim 14 (depends on 12)

The method of claim 12, wherein the one or more biasing members is a fluid, and causing comprises causing movement of the one or more biasing members by pressurizing the fluid.

### Claim 15 (depends on 12)

The apparatus of claim 12, wherein causing comprises causing movement of a first biasing member at a first pressure, to achieve movement of the first pin set, and movement of a second biasing member at a second pressure, to achieve movement of the second pin set.

### Claim 16 (depends on 12)

The method of claim 12, wherein determining comprises determining the position of an and of each pin in at least the first pin set and the second pin set that engages the foot plantar surface to obtain a positional point of each pin, said positional points collectively defining a surface map.

### Claim 17

A method, comprising:
engaging a center engagement structure against a localized mid-foot region of a plantar surface of a subject's foot to adjust one or more mid-foot bones into a restored bone state, said engagement structure longitudinally positioned to achieve contact with the plantar surface prior to contact with an optional peripheral engagement structure, and;
determining a surface map of the plantar surface of the foot with the mid-foot bone in its restored bone state.

### Claim 18 (depends on 17)

The method of claim 17, further comprising engaging one or more peripheral engagement structures against a region other than the mid-foot region to contact the plantar surface while maintaining the engagement of the center structure.

### Claim 19 (depends on 18)

The method of claim 18, further comprising obtaining positional information of the one or more peripheral engagement structures, and from the positional information determining the surface map.
