 This protocol can replace an heavy examination with echography combinated with Larsen. the aim is studying the global vascularization by checking restoration time and his level on the hand after a cooling.

 This thermal camera is very sensitive meaning that the stimulation is improving the situation and pinpoint better the pain area, main pain is corresponding to the patient's experience.
-All of this means that stimulation, in some case is better, than a long rest with unpredictable results. Forcing the body to react with a controlled stimulation allow a better measurment and permit a comparison for cases under treatment. Keep in mind that a treatment can be long and that season and weather are changing, a cold/hot stimulation can then erase environment effect and allowing a more neutral situation where the real body situation is displayed. This means too that you are more relaxed into the timing of the examination and can perform the stimulation 10 minuts to one hour in advance.

 Results are impressive, we see that despite the thermal contrast decrease, image is far more readable. Worst, that pain area was not readable in static mode but perfectly displayed after dynamic stimulation.
