ClinConnect Summary
This clinical trial is exploring how certain techniques, called neuromodulation methods, can help relieve phantom limb pain in individuals who have had an arm or leg amputated. Phantom limb pain is when a person feels pain in a limb that is no longer there. The study involves applying gentle electrical stimulation to specific nerves in the body to see if it can reduce this pain. Participants will have different types of stimulation, including methods that target the spinal cord and other areas of the nervous system.
To join the study, participants should be between 18 and 65 years old and have experienced the loss of an arm or leg at least six months prior. They must also be dealing with ongoing pain, rated between 4 and 10 on a scale where 0 means no pain and 10 means the worst pain possible. It's important to note that some individuals may not qualify to participate, especially if they have certain medical or psychological conditions. If eligible, participants can expect to undergo a procedure where electrodes are placed to stimulate the nerves, and they will be monitored for changes in their pain levels throughout the study.
