From Probe to Needle - A Deep Dive Into The NCM
Since the patent was published in 1925 for the first Neurocalometer (NCM) the fundamental features and concept of the device has stood the test of time.
From the 6 thermocouples that make up each probe, to the panel meter with the swinging needle. We will be taking a deep dive into the inner workings of the NCM.
Q: What is an Neurocalometer (NCM)?
The NCM is a nerve heat measuring device that measures the heat differential of the spinal column via the two thermocouple probes which touch the surface of the skin. When the information from the probes is received by the panel meter (often called in the Chiropractic community as the potentiometer), the needle on the panel meter will swing back and forth, showing the temperature differential. This information is then interpreted by the Chiropractor to determine a few different things. Whether or not the patient needs an adjustment, if the patient is in stress, if the patient has been adjusted, and if so, how well the adjustment was received in the body. the best part about this device is, no processing power or batteries needed.
Q: What is a Thermocouple?
Our journey really starts with the thermocouple probes. A thermocouple is made of two dissimilar metals that when a heat is applied, an electrical charge is produced, widely known as the Seebeck Effect [1]. Once the Seebeck Effect takes place and the heat energy is converted into electrical energy, we can now go on to the next step.
Q: What is an Analog Panel Meter?
Having transformed our heat energy into electrical energy, the next step involves converting this electrical energy into mechanical energy, allowing us to interpret the changes. This conversion is achieved using an analog panel meter. The key components of the panel meter are the electromagnetic coil and the permanent magnet. The interaction of electric current with the coil, set within the magnetic field of the permanent magnet, results in motion [2]. The movement of the coil, under the influence of electric current, applies a deflecting torque, pivoting it to an extent that corresponds to the magnitude of the current. This motion moves a needle or pointer, translating the electric current into a mechanical display. Through this transformation from heat to mechanical energy, we derive our differential readings.
Conclusion
From the second the probes are placed on the skin of the patient, the NCM instantly is ready to present the data in a clear and intuitive way where any trained Chiropractor can read. No batteries required, every step of processing within the device is naturally governed by natural phenomenons that are found in physics, making the NCM one of its kind.
Bringing this type of consistent analysis to Chiropractic care brings quality care to any patient receiving care under the chiropractor using this device. Not only that, it bring confidence to the chiropractor, knowing that they can produce consistent quality care for each patient.
