Abstract
A method and apparatus for measurement and distinguishing between brawny and pitting oedema comprises a measurement head including a tactile sensor to measure a first characteristic of the oedema and a force decay sensor mounted adjacent the tactile sensor, to measure a second characteristic of the oedema so as to distinguish brawny oedema from pitting oedema. The tactile sensor may be a resonance oscillating sensor which may determine frequency shift, and the forced decay sensor may provide information regarding the degree of displaced fluid as a measure of pitting oedema through measurement of decay of force.
