What makes InBody technology different?

Traditional BIA technology measures the human body as a single-cylinder using one frequency, which increases the likelihood of inaccurate results.

Conventional BIA devices use empirical estimations based on factors like age and sex to help improve accuracy. While this may work for people with a standard

body type,it is inaccurate for those who do not fit this mold, such as fit elderly adults.Everyone has a unique body composition—

that’s why InBody makesinnovative technology tailored to the individual, not a group. InBody’s medical-grade body composition analyzers use four pillars of

technology to provide accurate, precise direct segmental measurement multi-frequency bioelectrical impedance analysis (DSM-MFBIA)

extensively validated to gold-standard methods.

What is Bioelectrical Impedance Analysis (BIA)?

Bioelectrical impedance analysis (BIA) is a method for measuring body composition, including muscle mass, body fat, and total body water. Alternating low and

high-frequency electrical currents are sent through the water in the body via contact with electrodes to measure impedance.The impedance is used to

determinetotal body water (TBW), which can then be used to derive your fat-free mass—the portion of your body that does not contain fat, including your

muscle and bone—and finally, body fat.

Multiple Frequencies

InBody uses multiple currents at varying frequencies to provide precise body water analysis.

8-Point Tactile Electrode System

When measuring impedance with electrodes, contact resistance occurs. InBody accounts for contact resistance with strategically placed electrodes to ensure that measurements are accurate and reproducible.

Direct Segmental Measurements

InBody measures each of the body’s five cylinders (left arm, right arm, torso, left leg, and right leg) to deliver accurate and detailed results.

No Empirical Estimations

InBody measures each of the body’s five cylinders (left arm, right arm, torso, left leg, and right leg) to deliver accurate and detailed results.

01

Multiple Frequencies

Other BIA Devices

The ability to distinguish between extracellular and total body water is critical to identify fluid imbalances related to

acute inflammation or edema. Many BIA devices use only one frequency at 50 kHz to measure impedance, which

does not fully pass through the body’s cells and makes the accurate measurement of total body water impossible.

As a result, patients with increased extracellular water may have overlooked health risks.

InBody Devices

InBody uses a combination of low and high frequencies to accurately determine extracellular, intracellular, and total

body water. The use of multiple frequencies allows InBody devices to achieve a high level of precision.

Medical practitioners can use InBody for measurements of body composition and fluid status.

02

8-Point Tactile Electrode System

Other BIA Devices

Many BIA devices lack a thumb electrode or have hand electrodes positioned close together. These designs can

cause measurements to start in the palm, which has a high impedance and can cause inaccuracies or lead to

inconsistent measurement starting points, reducing the reliability of results.

03

Direct Segmental Multi-Frequency Bioelectrical Impedance Analysis (DSM-MFBIA)

Other BIA Devices

Traditional BIA views the human body as one cylinder. However, the short length and large cross-sectional area of the

torso mean that even a minor measurement mistake can lead to substantial error. For the most accurate results,

BIA devices should measure the torso separately.

InBody Devices

Direct segmental measurement bioelectrical impedance analysis regards the human body as five cylinders: left arm,

right arm, torso, left leg, and right leg. InBody independently measures each cylinder to provide accurate

measurements for the entire body.

04

No Empirical Estimations

Other BIA Devices

Many BIA devices use empirical equations to compensate for technological flaws, including the lack of torso

impedance (due to whole-body impedance measurement), single frequency measurements (which are unable to

differentiate between water compartments), and lack of reproducibility (from electrode placement or positioning).

These empirical equations utilize data, such as age, sex, and ethnicity, to calculate body composition based on

common trends rather than relying solely on the individual’s actual body composition.

InBody Devices

InBody measures body composition without relying on empirical assumptions based on age, sex, ethnicity, or body

shape, producing accurate and precise results validated to gold standard methods. Simply put, InBody provides

individualized feedback for progress tracking to help you achieve your goals.
