System, method and apparatus for determining the thickness of orthotics needed to correct for differences in leg length

1. A method for providing a measurement of the difference, if any, of left and right leg lengths of a person, in order to determine a thickness of an orthotic insert for a left shoe and a right shoe, the method comprising the steps of:

providing an apparatus with a left surface and a right surface, the left surface associated with a first scale and the right surface associated with a second scale and wherein the apparatus is configured to independently lift and lower the left surface and the right surface to predetermined stops while the person is standing on the left surface and the right surface and to sense pressure with pressure sensors comprising a first pressure sensor associated with the left surface and a second pressure sensor associated with the right surface, the apparatus further comprising a processor operatively connected to the first scale and the second scale and the pressure sensors;

weighing a person's weight bearing through both a left foot with the first scale, and simultaneously and independently weighing the person's weight bearing through a right foot with the second scale;

changing a height of the left surface or the right surface from a neutral position between the person's left and right feet during said simultaneous and independent weight measurements by lifting or lowering the left surface and/or the right surface to the predetermined stops, such that the weight associated with the first scale and the weight associated with the second scale is an indication of said person's center of gravity bearing through the left and right legs;

sensing pressure using the first pressure sensor of the first scale and the second pressure sensor of the second scale to provide pressure data; and

using the processor to determine the thickness of the orthotic insert for the left shoe and the right shoe to even foot pressures for compensating for unequal leg lengths using the sensed pressure and a height difference between the left surface and the right surface.

2. The method of claim 1 wherein the apparatus further comprises a display operatively connected to the processor.

3. A method for providing a measurement of the difference, if any, of left and right leg lengths of a person, in order to determine a thickness of an orthotic insert for a left shoe and a right shoe, the method comprising the steps of:

weighing a person's weight bearing through both a left foot with the first scale, and simultaneously and independently weighing the person's weight bearing through a right foot with the second scale;

changing a height of the left surface or the right surface from a neutral position between the person's left and right feet during said simultaneous and independent weight measurements by lifting or lowering the left surface and/or the right surface to the predetermined stops;

sensing pressure using the first pressure sensor of the first scale and the second pressure sensor of the second scale to provide pressure data; and

using the processor to determine the thickness of the orthotic insert for the left shoe and the right shoe to even foot pressures by for compensating for unequal leg lengths using the sensed pressure and a height difference between the left surface and the right surface.
