Postamputation Pain: Peripheral Mechanisms

Postamputation Pain: Peripheral Mechanisms

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.

Inclusion Criteria:

• Amputees with chronic amputation pain (stump or phantom pain) 3 or above on NRS (numerical ratio scale).

Exclusion Criteria:

• Severe somatic or psychiatric diseases
• Other peripheral neuropathy
• Lack of ability to cooperate to the clinical examination
• Allergy to Lidocaine or similar analgetics
