The study evaluates the relationship between the duration of evolution of SDRC1 and the efficacy of continuous peripheral nerve block (c-PNB) associated with an intensive rehabilitation program to improve the therapeutic strategy of SDRC1.

The main hypothesis of this study is that if c-PNB is proposed earlier, the recovery, measured with a scale achievement of objectives, will be better.
