Clinical Trial Summary

Selected measurements in healthy persons of skin tissue dielectric constant as reference values for subsequent use to evaluate patients with head and neck lymphedema.

Description:

Skin tissue dielectric constant (TDC) measurements will non-invasively be made bilaterally at two neck sites, bilaterally on two forearm sites and one site at the chin sub-mental area.

Measurements are made with subjects fully clothed and seated. Measurements are made in triplicate and averaged at each site. Full measurements take about 5-7 minutest to complete. Data will be analyzed to determine the neck-to-arm ratios and chin-to-arm ratios to establish normal ranges of these parameters for subsequent use as comparisons to evaluate and track changes in patients with head and neck lymphedema.
