Mirror therapy is a rehabilitation technique that uses a mirror to create the visual illusion of movement in an impaired limb. It has been shown to help reduce pain and improve motor function for various conditions like stroke, phantom limb pain, and Complex Regional Pain Syndrome (CRPS). Several studies reviewed found mirror therapy to have a significant positive effect on motor function and activities of daily living for stroke patients, and on reducing pain for phantom limb pain and CRPS. While more high-quality research is still needed, mirror therapy shows promise as a low-cost, low-risk adjunct to traditional rehabilitation methods.
