Summary

This completed study looked at whether giving a continuous nerve block along with intensive physical and occupational therapy can improve recovery in people with Complex Regional Pain Syndrome type 1 (CRPS 1). The study enrolled 30 patients and followed them for up to a year. The main goal was to see if starting this treatment earlier leads to better results.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: continuous peripheral nerve block (CPNB) plus intensive rehabilitation program
What this could lead to: If successful, this could point toward a more effective treatment strategy for CRPS type 1, especially if started earlier in the disease course.
What could go wrong: This is a small, completed study with only 30 participants and no control group, so results may not be generalizable. The nerve block procedure carries risks like infection or nerve damage.
