Variable Name:
The name of the variable used to perform a function. Each variable name can be named uniquely on each system, so actual names may refer you to a different root name. For example: kirbyd can also be used as kerbyd and looked up under either name when F1 is pressed.

Defines the name of the Nth accomodation to apply to a device. More commonly used names are aliased to single digit numbers.
Note: For any accomodation design, the name must be above all other accomodation variables.
When a0name is used, all variable assignments following the name are considered applied to the current accomodation assigned by a0name, effectively allowing one to apply an accomodation, and modifying the current accomodation. Subsequent assignments using a0name then push a new accomodation onto the accomodation stack, thus allowing for a single subset of accomodation modifiers for all accomodations. Although a1name through a9name could be used, this is not recommended.

This variable determines which feet to apply the Nth accommodation to.
0 - Bilateral
1 - Left Only
2 - Right Only

If (-1 <= value >= 1) the accommodation size is adjusted as a percentage of the width of the device.
If ( -1 > value < 1 ) the accommodation is adjusted by an absolute value in mm.

If (-1 <= value >= 1) the accommodation size is adjusted as a percentage of the length of the device.
If ( -1 > value < 1 ) the accommodation is adjusted by an absolute value in mm.

Used to adjust the position of the Nth accommodation.
if ( -1 > value < 1) then the value represents a percentage of the width of the device.
if ( -1 < value > 1) then the value represents an absolute adjustment in mm.
A positive value moves the accommodation towards the medial side of the device, whereas a negative value moves it towards the lateral side.

Used to adjust the distal position of the Nth accommodation.
if ( -1 > value < 1) then the value represents a percentage of the length of the device.
if ( -1 < value > 1) then the value represents an absolute adjustment in mm.
A positive value moves the accommodation towards the distal side of the device, whereas a negative value moves it towards the proximal side.

A value of 1 defines no arch fill. Decreasing values increase the amount of arch fill.

Normally, the arch contour is calculated properly, and an archfill region is created. This variable is used to prevent the arch fill from inappropriately filling in the heel area. Thus, the number for archfill should always be greater than 1

Used in conjunction with lct to reduce the bulk of devices, such as dress devices.

Defines the distal edge angle of the left foot. This is commonly used in blake inverted devices.

Example:
code: blake
Variables:
deal=rfl*(-1)
dear=rfr*(-1)

At a given percentage of orthotic length, the power applied to the Distal edge angle is at its minimum. At 100% of orthotic length the power applied to the device is at maximum.

This variable determines the power of the equations used to redefine the distal edge angle.

Defines the distal edge angle of the right foot

A radius is defined as a percentage of the length of the device, usually behind the distal edge. This radius is then used to define the shape of the distal edge. In cases where the device is abnormally long on one side or the other, this radius generally needs to be increased to avoid the radius turning in on itself. (Intoe and outtoe designs)

Starting at the beginning of tapering, the thickness is decreased as a power function until it reaches the final thickness at the edge.

This variable is normally entered into a prescription form.

Used to define how far from the distal end of the device to terminate the midfoot grind or flange out on the lateral side.

Used to define how far from the heel post the midfoot grind or flange out will start on the lateral side

This variable is used to define the types of midfoot perimeter modifications are desired. The values are defined as follows:

• 0 - No midfoot grind or flange
• 1 - Medial Midfoot grind
• 2 - Lateral Midfoot grind
• 3 - Medial & Lateral Midfoot grind
• 4 - Medial Flange out
• 5 - Medial Flange out & Lateral Midfoot grind
• 6 - Not implemented
• 7 - Not implemented

• 0 or 3 - Both feet
• 1 - Left foot only
• 2 - Right foot only

Used to define how far from the heel post the midfoot grind or flange out will start.

Used to define how far from the distal end of the device to terminate the midfoot grind or flange out.

This variable enables you to modify the heel rim to its predefined height and cleans up the transition areas both medial and lateral. It is designed to correct for a multitude of problems when the surface equation cannot meet the expectations in terms of heel height/arch height

Example for default design standards
hdfix=true
hdfixl=1.3
hdfixd=1/hdfixl
hdfixw=0.8
hdfixp=5
hdfixdp=1


Example codes for V and W heel fixes

Code: vwfix1
hdfixw=0.7

Code: vwfix2
hdfixw=0.6

Code: vwfix3
hdfixw=0.5

Code: vwfix4
hdfixw=0.6 hdfixp=0.5

This variable defines the length of the heel depth fixing and blending function, as a percentage of the original heel rim length. Generally, hdfixd is set to 1/hdfixl, but this is not required, and could be used to extend a heel rim distal or proximal.

0 - Original method
1 - Prototype method
2 - No shaving

Defines the angle relative to the first, fifth and heel with which to file into the virtual positive device.

Used in conjunction with kirbya to determine the amount of heel skive filing on the "virtual" positive device. Effectively, it places a wedge on the medial side of the heel as defined by (link to document at a later date) .

When lateral column shaving is enabled, this variable defines the thickness on the lateral side of the device. Typically used to reduce bulk on dress and sport devices

This variable is normally entered into the default or custom prescription form.

This variable is normally entered into the default or custom prescription form.

Powers less than 1 define a convex shape for the flange, whereas powers greater than 1 define a concave shape.

Defines the beginning of tapering, aka feathering for the lateral side of the device. At this point, relative to the length of the device, tapering is at 0% and progresses to ltfymax to 100% feathering. If this variable is set to 0, tapering begins just anterior of the heel.

Starting at the beginning of tapering, the thickness is decreased as a power function until it reaches the final thickness at the edge.

Defines the position of maximum tapering (aka feathering) for the lateral side of the device.

• 0 - Polypro (translucent)
• 1 - Particle board positive
• 2 - Soft Accomodative
• 3 - Polypro (White)

Starting at the beginning of tapering, the thickness is decreased as a power function until it reaches the final thickness at the edge.

Powers less than 1 define a convex shape for the flange, whereas powers greater than 1 define a concave shape.

Defines the point at which medial tapering starts. At this point, relative to the length of the device, tapering is at 0% and progresses to mtfymax to 100% feathering. If this variable is set to 0, tapering begins anterior of the heel.

As it's common for a first metatarsal cutout to cause weakness in the forefoot post, this variable causes the forefoot post to sink behind the cutout, restoring the strength of the device. It is typically used only for first met cutouts, but may also be used in extremely heavy patients to provide added strength

Normally, this value is entered within the prescription as defined by a given laboratory's definition based on patient weight and classification. A future version of OreTek will learn the appropriate value based on how the data is entered as a function of patient weight and classification. Classification is a function defined by the laboratory, and is simply a label that associates pt to a given patient's weight.

Typically, when accommodations are applied to a device, the material is weakened. This variable allows a definition of a plastic thickness additive to adjust to specific designs transparent to the operator.

In order to reduce the bulk of a device, often the rearfoot thickness of the device is reduced, as there is no special benefit to maintaining thicknesses in this area. Often this thickness is set to a negative or near 0 value, especially in designs employing a cobra style of accomodation.

When set to 2, treats each foot as a unique order with the same prescription file and no averaging. Useful in cases such as polio victims where one foot's size greatly differs from the other.

A value of 0 means all top surface tapering
A value of 1 means all bottom surface tapering
Values between 0 and 1 determing how much tapering occurs on the bottom and top surfaces.

Note: This variable has no effect on distal edge tapering due to the nature of some bar and extrinsic forefoot postings.
