Have you have ever experienced thyroid problems that went unresolved or misdiagnosed for any length of time? In this demonstration, Dr. Michael Karlfeldt, ND, PhD explains how to use Applied Kinesiology or muscle-testing to determine whether the thyroid, which is part of the endocrine system, is malfunctioning in the body. 


We spoke to Sondra a little bit, and she’s been dealing with Grave’s Disease. And I was talking about how we went through different steps in order to support her thyroid to get back to normal. The test I was using to see what was going on in the body is a technique called Applied Kinesiology or muscle testing, or there is a more advanced form of it that I use in my office called Automatic Response Testing (ART). It’s a simple technique.

So I’m going to have Erica Casantos, she’s my willing subject today. Just going to have her stretch her arm straight up. Just test the arm, keep it really strong, just match my pressure. And what you do is apply pressure on the nerve endings that relate to the organ (placing his hand near the thyroid while placing pressure on the arm). And you see here, it goes weak. And I have my hand away, and it’s strong. And put it here (back near the thyroid), and it goes weak.

So that means there is something going on with this thyroid that we need to support. And then we want to figure out: what is it, what do we need to work on? So then you can use different vials that are actually different homeopathic solutions containing different infectious agents, different foods, chemicals, and metals. And you can test to see which one of these will impact the thyroid.

So when I place that vial on her, and the arm is still weak. And see here, it went strong. So then we know there is some kind of food which is impacting her. Different gluten foods, different dairy, here is eggs, sugar, corn, etc., and by introducing these you can pinpoint and see which one of these foods is creating inflammation and stress on the thyroid.

So I’m going to pinpoint which one it is. I will be using these different magnifying glasses. These magnify the signal of whatever vial it is that I’m putting them on. So I’m going to put them onto the gluten foods, and see if that’s the one. And that didn’t change anything. Then I will try the dairy foods. And that creates a change, right there. So then we know dairy, then, has an actual impact on the thyroid. I will then suggest for Erica to avoid dairy.

Then you can test, with these different vials here, they contain different hormonal substances. You can bring out the thyroid vial and test and see what’s impacting that thyroid vial. So I’m going to be placing that on what’s called signal enhancers. And you can see how her arm went strong. And if we put that on here, her thyroid gets strong also.

And then we can test and see if there is something that is impacting some nutrient that might be missing in order to be able to support this thyroid. And then there are other vials – one with amino acids, and the same for fatty acids, vitamins, and minerals. And you can test to see if any one of these creates a change within the thyroid. So I’m putting all of these amino acids on her and we just want to see, whether the arm is strong. If any of these impact her, the arm will go weak. And it didn’t go weak there.

Then we will try vitamins, didn’t create a change. Then we can try fatty acids, and that didn’t create a change. And then we’ll try minerals. And that created a change. So then we know there is some mineral that is supporting and impacting her thyroid function. And then we can go about finding out which mineral she needs to support thyroid function.

We can take it a step further, even. Every hormone has a receptor site that is needed to bind to within the cell. And sometimes this receptor site can get clogged up with chemicals, metals, or it could be some kind of infectious agent that is interfering with that receptor site. I have a vial for receptor sites also. So when I go to the thyroid receptor site, and test to determine how she is doing. After testing, I can see that didn’t change anything. But probing further to see what is interfering, I’m going to check to determine if the issue might be dairy again, and that does appear to be the problem. When I take the dairy away her arm is strong. When I place the vial back, the arm is weak.

In this instance, we then know that dairy impacts the receptor sites for the thyroid hormone. This is a way to get a clear picture of any organ system – endocrine or hormonal system, and others.
