Postamputation Pain: Peripheral Mechanisms

• Status: Completed
• Trial end date: 2018-02-28
• Target enrollment: 0
• Participant gender: All

Summary

Stump and phantom pain after amputation are common, but the responsible mechanisms are still not clarified. It has been suggested that phantom limb pain can be reduced by regional anaesthesia and in several recent studies, pain was reduced following intrathecal and intraforaminal blocks. In this study, the investigators want to investigate if spontaneous and evoked pain in amputees will be relieved by regional nerve blocks involving the damaged nerves.
