Eligibility Criteria 1. Male or female patients aged ≥18 years; 2. Static mechanical allodynia for less than 3 months, whatever its etiology and topography; 3. Probable peripheral or central neuropathic pain or defined according to the IASP criteria; 4. Neuropathic pain diagnostic questionnaire DN4 score ≥ 4/10; 5.

Patient not able to participate actively to the rehabilitation exercises for physical reason, cognitive reason (ability to understand instructions) or behavioural reason (e.g. addiction...); 3. Patient with complex regional pain syndrome (type I); 4. Patients for whom cares cannot avoid any touch with allodynia area; 5. Patient previously treated by a transcutaneous electrical nerve stimulation (TENS); 6. Prior treatment by somatosensory rehabilitation; 7. Duration of stay in the medical center \< 11 weeks; 8. Patient with cognitive disorder; 9. Allodynia area of the patient presenting with conditions not recommended for vibrotactile stimulation: wound, unhealed nerve suture, recent skin transplantation, fragile organ such as eye.
