CRPS (Complex Regional Pain Syndrome) Type I
Conditions
Brief summary
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.
Interventions
PROCEDUREIntensive rehabilitation program with CPNB
The patient will have an intensive rehabilitation program (two 30-minute kinesitherapy sessions every day and 30-minute occupational therapy sessions 5 days a week) with the CPNB. The patient will have follow-up consultation at 1 month, 3 month, 6 month and 1 year after the beggining of the intensive rehabilitation program

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The composite score (the summation of the 3 Goal Attainment Scaling (GAS) scores) | 1 year | The improvement of the composite score following BNPc combined with intensive rehabilitation. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain assessment | 1 year | EVA (Visual Analogue Scale, VAS) for all the patients at each visit This is a measure of pain intensity on a scale of 0 (no pain) to 10 (very severe pain). We will assess the percentage of pain relief with the EVA scale, before and after the PCNB. |
| Anxiety assessment | 1 year | Hospital Anxiety and Depression (HAD) scale for all the patients at each visit There will be 2 scores One to assess anxiety : from 0 to 21 and one to assess depression : from 0 to 21 Higher scores mean a worse outcome. |
| Arthrometry assessment | 1 year | For an upper limb block : Passive and active arthrometry (angular measurements for shoulder, elbow and wrist) For a block of the lower limb : Passive and active arthrometry (angular measurements for hip, knee and ankle) |
| hand joint assessment | 1 year | For an upper limb block : Kapandji Index at each visit (between 0 to 10) |
| gripping force assessment | 1 year | For an upper limb block, gripping force will be evaluated with a Jamar and Pinch dynamometer at each visit after BNPc |
| activity assessment | 1 year | For an upper limb block, the activity limitation will be evaluated by leroux's scapular index (LSI) with a global score out of 100 at each visit after BNPc |
| manual dexterity test | 1 year | For an upper limb block, the dexterity will be evaluated by a Box and Block Test at each visit after BNPc |
| Assessment of activity limitation for a block of the upper limb | 1 year | DASH scale at each visit |
| Assessment of activity limitation for a block of the lower limb | 1 year | WOMAC score at each visit |
| Assessment of functional capacity | 1 year | TDM6 at each visit (number of metres travelled by the patient during 6 minutes) |
| Assessment of the restriction of participation in social life | 1 year | Return to work |
| Evaluation of the effective dose | During the CPNB | \- Recording of effective doses (continuous and bolus) |
| Evaluation of the tolerance of CPNB | During the CPNB | \- Incident reporting |
