Bioimpedance Devices for Detection of Lymphedema


Bioimpedance devices or bioelectrical impedance spectroscopy devices are a non-invasive technology and have been proposed for use as a tool to diagnose lymphedema. Bioimpedance compares resistance to electrical current in different compartments as tissue impedance decreases with the accumulation of excess interstitial fluid.

Secondary lymphedema may develop following surgery for breast cancer. This condition results from lymphatic dysfunction or disruption and can be difficult to accurately diagnose and manage. One challenge is identifying the presence of clinically significant limb swelling through simple noninvasive methods. Many techniques have been used for documenting lymphedema including measuring differences in limb volume (volume displacement) and limb circumference. A number of newer techniques are being evaluated, including bioimpedance with use of bioimpedance spectroscopy (BIS) analysis (e.g., ImpediMed LDex┬«  U400). BIS is based on the theory that the amount of opposition to flow of electric current (impedance) through the body is inversely proportional to the volume of fluid in the tissue.




There is a lack of scientific evidence to verify the technical and diagnostic performance of bioimpedance testing in the diagnosis of secondary lymphedema, especially for subclinical disease. There are no data from comparative clinical trials that demonstrate the impact of the test on clinical outcomes.
