Teaching the brain about pain in carpal tunnel syndrome

Carpal tunnel syndrome causes pain, numbness, and weakness in the hand and wrist. Some people with this condition have pain that persists because their nervous system has become overly sensitive — a condition called nocioplastic pain. This trial tests whether combining a desensitization technique (gradually retraining your hand to tolerate touch and sensation) with education about how pain works can reduce symptoms better than desensitization alone.

Standard treatments for carpal tunnel syndrome don't always work well for people whose pain is driven by nervous system sensitization rather than just nerve compression. Learning how pain actually works in the brain may help people manage their symptoms more effectively when combined with hands-on retraining.
