A story started in Italy
Bioelectrical Impedance Analysis has a long history and dates back all the way to 1786, when the Italian physicist Galvani experimented with tissue structures in a frog and observed the influence electrical current had on it. As he did not further develop his studies into a more defined format, however, it was not until much later, at around the 1960th that the subject regained new attention.
Thomasset, a French Physician was sure that he could reflect the fluid content of the human body through electrical resistance. As a result, in 1962, he and his colleagues developed one of the first impedance analyzers to measure biological tissues.
Nyboer, an American researcher was finally able to prove that impedance values do actually permit us to draw conclusions about our bodily composition, and around 1970, he laid down what is known today as the foundation of the modern form of impedance analysis. In the 1980’s the term bioelectrical impedance analysis was finally established as the name for the method. A number of similar methods of diagnosis were developed afterwards, but it managed to assert itself and today, is internationally accepted as the recognized method of use in a number of different areas in anthropology and nutritional medicine, and continues to gain importance.
Specialists around the world now take the opportunity to regularly meet at the BIA Consensus Conference that takes place at the American National Institute of Health NIH, to share and exchange their experiences, a sign of the continued further development and interest in this subject. The use of impedance analysis is a reliable, simple, and highly cost-effective method, and provides medical practitioners with the opportunity to make differential diagnosis. A broad spectrum of instruments and software for specific areas of application that is developed continuously ensures ever-increasing precision and safety, and forms the basis for objective, long-term approaches to treatment.
Bioelectric impedance analysis (BIA) is the term representative for a variety of traditional and new noninvasive procedures and technologies that use electric current. With the help of one or more surface electrodes, a tiny amount of electrical current is activated and is detected at surface electrodes placed elsewhere on the body, once the resultant electricity pulse has passed through.
As it quickly proceeds through the various physiological sections of the body, and passes through, a drop in voltage occurs. The current encounters impedance or resistance inherent in the fluids and tissues it passes through the various areas, among them the intracellular space, the lymphatic system, the bloodstream and others. The drop in voltage delivers indirect information about the physical properties of the sections, where current has passed through.
