Bioimpedanace spectrometry for lymphedema – pro
Bioimpedance spectroscopy (BIS) is based on the theory that the level of opposition to flow of electric current (impedance) through the body is inversely proportional to the volume of fluid in the tissue. In lymphedema, with the accumulation of excess interstitial fluid, tissue impedance decreases. The idea is to diagnosed and treated lymphedema early.
Using bioimpedance spectroscopy to measure lymph fluid buildup seems better than using a tape measure to keep track of arm circumference for detecting lymphedema, according to early results from a study, Interim analysis lymphedema ‘PREVENT’ trial, was presented on May 2, 2019, at the American Society of Breast Surgeons annual meeting in Dallas. A few studies had been performed by NCCN PDQ do not specifically mention it and it remains E/I at this time. few studies had been performed but NCCN and PDQ does not specifically mention it and it remains E/I at this time.
