Operational Equivalence of Bioimpedance Indices and Perometry for the Assessment of Unilateral Arm Lymphedema

Abstract

Bioelectrical impedance analysis, although not providing a quantitative volume measurement of lymphedema, provides a measurement index that is highly correlated with quantitative measurements of the volume increase in limb size seen in lymphedema. The speed and ease of the impedance technique renders it a suitable alternative to perometry for the assessment of lymphedema.
