Study Details

Study Description

Brief Summary

In CRPS, perturbation of body image and pseudo-neglect syndrome of the body part affected are frequently found. Pain and sensory perturbation seems to modify the way patients perceived their body part affected.

Does a local body image perturbation can affect the balanced of the global self-awareness?

Condition or Disease	Intervention/Treatment	Phase
Complex Regional Pain Syndromes	Other: Sensory testing in the two hand Other: Neuropsychological evaluation

Detailed Description

With the investigation of spontaneous sensations (SPS) according to the protocol of Michael and al (2011) the investigators study how patients can listen to their internal sensations located in other body part than the painful member in order to construct a representation of the body and maintain it in active consciousness. A group of controls will be included to understand if there is a global modification in the perception of SPS witch may be linked to the pathology.
