Virtual reality glasses tested to trick the brain and ease chronic pain

This small study tested whether adding augmented reality mirror therapy to standard physical therapy helps people with complex regional pain syndrome (CRPS) in their arm. CRPS causes severe, long-lasting pain, swelling, and movement problems. Researchers had patients use special glasses that show a virtual, healthy-moving arm to see if this 'visual trick' improves real arm function, reduces pain, and enhances quality of life compared to standard therapy alone.
