Mirror Visual Feedback Therapy is an emerging rehabilitation approach derived from the mirror neuron theory, which has been increasingly applied in the rehabilitation of post-stroke motor aphasia in recent years. Mirror visual feedback therapy can effectively ameliorate speech disorders in patients with post-stroke motor aphasia, enhancing their spontaneous speech, repetition, naming abilities, and articulation clarity, thereby improving their capacity for daily communication. This paper discusses the background and development of mirror visual feedback therapy, the therapeutic apparatus involved, its potential mechanisms of action in the treatment of post-stroke motor aphasia, and its clinical applications, aiming to provide novel insights for the rehabilitation of post-stroke motor aphasia.
