Evaluation of the Physiodoloris Pain Monitor in Patients With Complex Regional Pain Syndrome

Evaluation of Non-invasive Monitor of Physiodoloris Pain in Patients With Complex Regional Pain Syndrome Treated by Nerve Block (Prospective Monocenter Study)

A French University team (M. Jeanne, MD, and M. LOGIER, Ph D) have developed a pain assessment tool based on the analysis of the variability heart rate which evaluates the Analgesia Nociception Index (ANI). This index is intended to give a quantification of pain.

The aim of the present study is to assess the validity of the ANI parameter in patients with Complex Regional Pain Syndrome treated with a nerve block (reversible pain).

Inclusion Criteria:

• patients suffering from a Complex Regional Pain Syndrome of the upper or lower limb

Exclusion Criteria:

• contra-indication of a nerve block,
• contra-indication of the use of the pain monitor
