A mirror therapy box is a rehabilitation device that creates the visual illusion of movement in an affected or paralyzed limb by reflecting the motions of the healthy limb. This visual feedback helps the brain “relearn” motor functions, improves coordination, and can reduce pain signals associated with conditions like phantom limb syndrome. It is widely used in stroke rehabilitation, neurological recovery, and for patients experiencing motor impairments, providing a non-invasive and effective method to enhance neural plasticity and functional recovery.
