Mirror Neurons and Stroke Rehabilitation

Mirror neurons are thought to help stroke patients recover their motor function. Read about what proves this, how this works, and what this means for the future of stroke rehabilitation.

What is a Stroke, and why are Mirror Neurons thought to help Recovery?

A stroke is a medical emergency when something prevents your brain from getting enough blood flow, such as a blocked blood vessel or bleeding in your brain. This causes your brain cells to die, and damage can be severe, causing permanent disabilities. Common effects of a stroke include paralysis, sensory changes, visual problems, speech problems, and problems with thinking and memory.

 Mirror neurons are specialized brain cells that fire both when an individual does an action and when they observe that same action. Because of this, mirror neurons are thought to aid stroke recovery because patients with paralysis or severe weakness can still activate their motor pathways just by watching an action, as mirror neurons activate the brain’s motor region. Furthermore, firing these neurons encourages the brain to form new neural pathways and reassign movement control from damaged areas to healthier ones, promoting neuroplasticity. Also, by keeping the motor cortex active even when a limb cannot physically move, the brain is prevented from abandoning the affected side of the body entirely. These are all reasons why the mirror neuron system is thought to help stroke patients recover their motor functions.

What Studies Say

There are several studies that have shown that utilizing the mirror neuron system may be able to help stroke victims recover their motor function. A review published in 2010 argued that therapies based on action observation, imitation, and motor imagery may help stroke patients recover motor function by engaging mirror neuron networks even when actual movement is difficult. It proposed that observing actions can activate premotor and parietal motor circuits and potentially promote neuroplasticity after stroke. Another review published in 2018 analyzed 19 neuroimaging and EEG studies, and it was found that action observation activated mirror neuron system regions in stroke survivors. The authors concluded that that mirror-neuron-related activation may contribute to motor relearning and recovery after stroke.

Mirror Therapy

 The growing evidence that action observation and mirror-neuron-related brain activity can support motor recovery after stroke helped inspire the development of mirror therapy, a rehabilitation technique when a patient has pain or disability on one side, such as one arm. A mirror is placed along a patient's midline, reflecting the movements of the unaffected limb so that it appears as though the paralyzed or affected limb is moving normally. When the patient performs movements with their healthy limb while watching the reflection, the brain receives visual feedback that creates the illusion of movement in the impaired limb.

 Researchers believe mirror therapy may work by activating the mirror neuron system and motor regions of the brain, as new connections are formed that can help support recovery, even if the limb isn’t actually being moved.

 Preliminary research has shown promising results, as a 2024 review found that mirror therapy can improve the motor control, balance, gait, and ease of daily activities in many stroke patients. Although researchers continue to investigate the exact mechanisms behind its effectiveness, many studies suggest that mirror therapy can provide meaningful benefits for motor recovery after stroke.
