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.
