The Equivalency of the Imp SFB7+ (L-Dex U400) With the Imp XCA Device
Study Overview
Status
Conditions
Detailed Description
When Lymphoedema is present, lymph and other fluids build up in the interstitial spaces of the tissues. This results in an overall increase in the total amount of extracellular fluid (ECF) in the limb, causing swelling. This can be documented by measuring the impedance (opposition) to a low frequency current that has been passed into the limb. Low frequency current travels predominantly through the ECF, where the Lymphoedema manifests. As the fluid builds up in the limb, the impedance to the current decreases and it is in this way that low frequency bioimpedance is able to assess Lymphoedema.
Multi-frequency bio-impedance analysis otherwise known as Bioimpedance Spectroscopy (BIS) has been reported to be effective for the measurement of ECF and sub clinical changes in ECF to predict the onset of Lymphoedema in the arms in studies conducted by Cornish et al. It has been reported by Warren et al that BIS can be used as a reliable and accurate tool for documenting presence of lymphoedema in patients with wither upper- or lower-extremity swelling.
The Imp™ XCA device uses an "impedance ratio" methodology to assess unilateral Lymphoedema of the arm. By this method the unaffected arm acts as an internal and subject specific control. The Imp SFB7+ (L-Dex U400) uses the same principles but at a lower frequency. This study is designed to show the equivalence of the 2 devices in assessing unilateral Lymphoedema of the arm.
