[A new diagnosis in polyneuropathy syndromes: hyperthermal laser Doppler flowmetry].
4 groups of 10 subjects were investigated with the new equipment of hyperthermal Laser-Doppler-Flowmetry for diagnosis of polyneuropathies (PN). Group 1 was healthy, group 2 was suffering from paraesthesia, group 3 from perception disorders and group 4 from motoric dysfunction as complications of a diabetic polyneuropathy. The time from onset of hyperthermia to increase of microcirculation ("hyperthermal latency") was determined as well as onset perfusion values and maximal perfusion values. The hyperthermal latency increased in higher groups of PN in a significant manner. The maximal perfusion decreased in higher groups. So the hyperthermal Laser-Doppler-Flowmetry is the first method suited to diagnose in routine a PN in a very early phase.
