BTD Forums  /  The GenoType Diet  /  Which Genotype when one leg is longer???
Posted by: Captain_Janeway, Tuesday, January 8, 2008, 8:28pm
My father has been told by his chiropractor that his left leg is slightly longer than the other. How can you possibly determine which genotype you are if the longer leg would make a difference between torso and leg length? What about amputees?

Use what you have to get a short list of possibilities, then strength test.

On page 78 of the book (under "Teeth Patterns"), Dr. D says, "Of course, if you've had dental work done on any of the teeth we're interested in, you won't be able to answer these questions....  Don't worry, there are plenty of other questions!"

Admittedly, leg measurements are more pivotal to determining one's GenoType than tooth patterns are.  But I believe that the same principle would apply -- use whatever information you've got, and find the best fit.

Believe it or not, I came to this conclusion several nights ago, while I was falling asleep.  I'm not an amputee, I just like to take everything into consideration!

Dr. D and I double-posted there.

*Whew!*  Looks like I guessed right!   ;D

I think it will be a toss up between teacher or explorer. He is type A, but I'm not sure about his teeth,but based on his health,which is exceptionally good for his age only one person in his family has had cancer and that type of cancer was exceptionally rare.

A agree with Dr. D. that you should use the information that you have and strength test from there.  

What could also be considered in a situation where one leg is shorter than the other, is whether the shortness is due to an anatomical short leg or a functional short leg.  Meaning, is the leg shorter because it is an asymmetry, or, for example, is it shorter because the pelvis has a tilt.  In the later scenario, I would measure the leg that seems longer (although in reality it isn't longer, just seems so due to the tilted pelvis).  The Chiropractor should be able to answer this question for your father.

Reread page 95 and remember that your Genotype is 100% confirmed based on the Advanced GenoType Calculator tables if you have your blood type, Rh, secretor status and your torso, leg, and finger length measurements.

You don't need the other measurements and data points to determine your GT. All they will do is help you determine how well you match the typical characteristics of your GT.

For example, If I used strength testing to determine my GT after using the advanced GT calculator tables. I would be a different GT. It doesn't work that way so don't do it.

So his height changes, depending on which leg he's standing on, and that's enough difference to skew the torso/leg measurement? Everyone I know who has gone to a chiropractor has been told one leg is longer than the other, but the difference is usually slight.

If it's more than a slight difference, upon measuring, as you said, then go with Dr. D.'s advice to strength test it.  

My sister is missing one vertebra, and the set of ribs that would normally come with it.  Just born that way.  Her torso was still longer than her legs, so we didn't have to think too much about it.

Thanks, that really does help!!

It may not be enough to make a significant difference for his torso to leg ratio,but he has problems with arthritis and neuropathy.He is not a diabetic,as neuropathy usually affects diabetics at some time, but a different doctor has basically told him this is "how he is wired".

The arthritis could affect the finger measurement. If you are unable to get a 'clean' measurment then it falls back to the strength test again.

The idea of the strength testing section was to provide a separate, independent method which could also be used in these types of situations.

By the way, any variation is fine (I like Lloyd's toilet seat idea the best, though it might prove hard to do in the clinic!) with torso-leg measurements, but the method given in the book is the standardized way to determine the 'cormic index' (seated to standing height ratio), so double check your results against the standardized method as well.

My right leg is about 3/8-1/2" shorter.  Naturally, this caused my pelvis to tilt down on the right side, and the tilt is what caused most of my back pain.  My spinal column had a sort of "S" curve when viewed from the front, but after a lot of adjustment/therapy, and wearing a heel lift, it has straightened out.  Your pelvis would only be naturally tilted if your spine was deformed!

Looking at my legs, it seems that the missing length is coming from my upper leg, but I haven't measured to verify.  In my case, I'd still be a Nomad either way!

I don't quite understand how you could have a "functional short leg" as you describe.  If both legs were identical in leg from hip joint to heel, and the pelvis was symmetrical, if the pelvis tilted one way, eventually the extra weight from walking and standing would push the lower side up, right?

Osteoarthritis can also cause the lower back to tilt, turning the pelvis.  That's kind of what I had in '98, though the surgeon had to go into a surgery before he could completely explain it to me... it ended up resolving with walking and BTD, and no more jogging.  My doctor sent me to the surgeon to get a heel lift, because he thought one leg was shorter, but that actually wasn't the issue.

An anatomical short leg is a leg that is literally shorter than the other.  You are born this way.  You are correct in saying that both a spinal curvature and this shorter leg could affect the tilt of a pelvis.  However, a functional short leg is where the legs are actually of equal length, but due to some functional issue it causes one to appear shorter than the other.  This functional issue usually is caused by the pelvis tilting.  The pelvic tilt could be caused simply by pulling your neck or back out, or even wearing high heels.  Say for instance the pelvis was caused to have a posterior tilt on the left.  This posterior tilt would take the entire hip joint with it, lifting it up and posterior.  This would cause the left leg to appear shorter than the right leg.  Fairly simple adjustments can fix this problem.
