Brief summary
This study aims to demonstrate that somatosensory rehabilitation of pain associated with static mechanical allodynia has superior efficacy over placebo treatment as well as over spontaneous changes.
Detailed description
This is a monocenter study. 45 patients will be enrolled in the study, allocated by randomization in 3 arms of 15 patients each. During the 38 week duration of the study, enrolled patients will be assessed at: * initial evaluation (first week of the study), * intermediary evaluation for every week and every modification of intensity of pain, * final evaluation at 10 weeks, * follow-up evaluation at 6 months.

Inclusion criteria
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. Chronic pain with average intensity ≥ 4/10; 6. Analgesic treatment unchanged within 15 days prior to screening, and not planned to be modified during the study; 7. Patient who can attend follow-up visits during the study; 8. Patient affiliated to a health insurance plan or entitled; 9. Patient must be able to give informed consent in accordance with ICH GCP guidelines and local legislation and/or regulations.
Exclusion criteria
1. Patient with neuralgia (spontaneous pain) with or without allodynia; 2. 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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of baseline in reduction of surface of allodynia area | At baseline, each week during the 10 week treatment period and at 6 months | Evaluate by the 15 g mono filament (Allodynographie) the reduction of surface of allodynia area |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change of baseline in reduction of pain | At baseline, at each week, at 10 weeks and at 6 months | Reduction of pain will be evaluated by QDSA questionnaire. |
| Change of baseline in reduction of allodynia intensity | At baseline, at each week, at 10 weeks and at 6 months | Reduction of allodynia intensity will be measured with the method with the colors |
| Change of baseline of patient's satisfaction with regard to received care | At baseline, at each week, at 10 weeks and at 6 months | Patient's satisfaction with regard to pain relief will be evaluated by VAS |
| Analgesics consumption | At 6 months | Amount of analgesic drugs |
| Afterglow effect | At 6 months | An evaluation of static mechanical allodynia in surface and intensity at 6 months |
