Abstract:
This study assessed the effects of changes in skin temperature on multifrequency bioimpedance analysis (MF-BIA) and on the prediction of body water compartments. Skin temperature (baseline 29.3 +/- 2.1 degrees C) of six healthy adults was raised over 50 min to 35.8 +/- 0.6 degrees C, followed by cooling for 20 min to 26.9 +/- 1.3 degrees C, by using an external heating and cooling blanket. MF-BIA was measured at both distal (conventional) and proximal electrode placements. Both distal and proximal impedance varied inversely with a change in skin temperature across all frequencies (5–500 kHz).

Abstract:
Multifrequency bioelectrical impedance analysis was used to estimate the ratio of extracellular water (ECW) to total body water in subjects with end-stage renal disease. The body's resistance was measured at frequencies ranging from 1 kHz to 1 MHz. The impedance index (height2/resistance) determined at low frequency (5 kHz) correlated most closely with ECW (r = 0.886) using sodium bromide dilution as the standard of comparison. In contrast, the ratio of height squared to resistance determined at high frequency (500 kHz) correlated most closely with total body water (r = 0.974) using deuterium

Abstract:
Multifrequency bioimpedance studies were performed in rats subjected to an eight-week swimming course followed by an eight-week no-exercise period and control animals. A significantly lower ratio of the phase angles of the bioelectrical impedance of the lung tissue at two frequencies of electric current in rats after prolonged physical activity in comparison with control animals was revealed, which may indicate structural and functional changes in the lung tissue. No significant differences were found in the bioimpedance of the myocardium of the left ventricle of the heart in rats of the two g

Abstract:
Multifrequency bioelectrical impedance analysis (MFBIA) was used to determine the intracellular (ICW) and extracellular water (ECW) compartments in rats. Resistance and reactance were measured on various body segments with frequencies ranging from 1 KHz to 1 MHz. After initial measurements, 0.9% NaCl was injected intravenously or intraperitoneally, and changes in ECW and ICW were estimated by MFBIA. Important differences were found between segments. In the leg, estimated ECW increased in proportion to the volume of intravenous fluid infused, whereas estimated ICW changed minimally. However, in

Abstract:
The present research aims to measure the segmental bioelectrical impedance (BI) of the human body at multifrequency, using a server user interface-based prototype, which provides subjects with measured data online anywhere accessed by their unique identifications. The present research measures the BI of the human leg and arm at a multifrequency range of 50–400 kHz with a developed and standard device. Recorded data can be transferred to the subject using Wi-Fi technology with their unique identifications and password. The system uses Wi-Fi interfacing for real-time data measurement and online

The aim of this study was a prospective detection of postoperative lymphedema of the lower limbs in patients after the surgery for cervical and vulvar cancer using different methods of examination and their comparison and monitoring of postoperative complications and quality of life. Totally 78 women were followed after the surgery for cervical cancer and 36 for carcinoma of the vulva. Due to the radicality of the surgery the patients were divided into the conservative and radical groups. Lower limbs lymphedema were evaluated preoperatively and 3, 6 and 12 months after the surgery by the measu
