Bioelectrical Impedance Analysis of Multi-frequency using Portable Small Impedance Measuring System

Bioelectrical impedance analysis revisited.

Although total limb volume measurements are used to track the progress of lymphedema and its treatment, these measurements can be confounded by changes other than fluid excess namely muscle or fat gain. Bioelectrical impedance analysis (BIA) is a technique that specifically quantifies both total body fluid and extracellular fluid in extremities. Whereas BIA has potential as a quick, inexpensive...

Validity of using multi-frequency bioelectrical impedance analysis to measure skeletal muscle mass in preschool children

[Purposes] Although it is recommended to develop a habit of physical activities, there is no easy way to measure skeletal muscle mass in preschool children, which cause the difficulty of evaluation. The purpose of this study was to examine the validity of body composition including the skeletal muscle mass assessment using multi-frequency bioelectrical impedance analysis by comparing body fat m...

Microfabricated Multi-frequency Particle Impedance Characterization System

We have developed a microfabricated flow-through impedance characterization system capable of performing AC, multi-frequency measurements on cells and other particles. The sensor measures both the resistive and reactive impedance of passing particles, at rates of up to 100 particles per second. Its operational bandwidth approaches 10 MHz with a signalto-noise ratio of approximately 40 dB. Parti...

Validation of Multi-Frequency Bioelectrical Impedance Analysis in Detecting Changes in Fluid Balance of Geriatric Patients

Validation of multi-frequency bioelectrical impedance analysis in detecting changes in fluid balance of geriatric patients.

OBJECTIVES Multi-Frequency Bioelectrical Impedance Analysis (MFBIA) is a quick, simple, and inexpensive method to assess body fluid compartments. This study aimed at determining the validity of MFBIA in detecting clinically relevant changes of fluid balance in geriatric patients. DESIGN A prospective, observational study. SETTING The 22-bed Geriatric Department of the University Hospital Ni...
