Use of Laser Speckle to Study Post Occlusive Reactive Hyperhemia in Healthy Subjects (SpeckleShake)
The investigators aim to test the hypothesis that Laser speckle contrast imaging allows for the measurement of cutaneous blood flow following various durations of tourniquet ischemia.

Other: tourniquet ischemia
Recording of cutaneous blood flow on the forearm at rest before and following tourniquet ischemias of 1 , 2 & 3 minutes
Ischemia and post occlusive reactive hyperemia in the skin is tested in healthy normal subjects for tourniquet ischemias of 1, 2 & 3 minutes at rest.
