Overview of the Quantum V Segmental BIA
The Quantum V Segmental BIA provides quantitative regional body composition assessments that are
similar to those produced by Dual-energy X-ray Absorptiometry (DXA) scanners. This is performed by
using eight hand and foot electrodes (left and right side) with the subject in a supine position and
measuring 13 resistance and reactance regions on the human body. The comparative characteristics of
segmental body composition assessments are highly significant, as segmental muscle atrophy and
hypertrophy can be clearly illustrated by analyzing and comparing collected data as a comparative
percentage or change over time.
Health care professionals such as physicians who are interested in regional muscle wasting will find the
Quantum V Segmental BIA a valuable tool. In addition, physical therapists, sport medicine trainers and
nutritionists can monitor and track their patient’s progress and health improvements on specific regions
of the body.
The Quantum V Segmental BIA uses an eight lead 12-channel multiplexer to quickly measure
resistance and reactance values from each arm, leg and right and left torso, including the upper and
lower regions of the human body in less than 20 seconds. The repeatability and accuracy of the
resistance and reactance measurements allow the smallest changes to be recorded with 0.1 ohms of
resolution.The phase angle of these regions is also illustrated.
