Background. Mirror visual feedback (MVF), a phenomenon where movement of one limb is perceived as movement of the other limb, has the capacity to alleviate phantom limb pain or promote motor recovery of the upper limbs after stroke. The tool has received great interest from health professionals; however, a clear understanding of the mechanisms underlying the neural recovery owing to MVF is lacking. Objective. We performed a systematic review to assess the effect of MVF on brain activation… Expand

Neurophysiological effects of mirror visual feedback in stroke patients with unilateral hemispheric damage
TLDR
Low-beta ERD dynamics may serve as a marker of neurophysiological response to MVF in research aimed to elucidate the factors influencing patients' clinical gain from this treatment. Expand
Parietal Activation Associated With Target-Directed Right Hand Movement Is Lateralized by Mirror Feedback to the Ipsilateral Hemisphere
TLDR
Functional magnetic resonance imaging was used to investigate the interaction of target directed movement and MVF on the activation of, and functional connectivity between, regions within the visuomotor network and revealed that the interaction between the ipsilateral parietal lobe and the motor cortex was significantly greater during target-directed movements with mirror feedback compared to veridical feedback. Expand
Role of kinaesthetic motor imagery in mirror-induced visual illusion as intervention in post-stroke rehabilitation
TLDR
Evidence based on brain imaging studies for testing the hypothesis that neural processes associated with kinaesthetic motor imagery are attributed to ipsilateral M1 activation is reviewed, relationships in terms of shared neural substrates and mental processes between mirror-induced visual illusion and kinaesthesia generate new evidence on the role of the latter in mirror therapy. Expand
The Mirror Illusion Increases Motor Cortex Excitability in Children With and Without Hemiparesis
TLDR
MI increases the excitability of M1 in hemiparetic patients with contralateral corticospinal organization and in typically developing subjects, providing neurophysiological evidence supporting the application of mirror therapy in selected children and adolescents with hemiparesis. Expand
Motor Cortex Plasticity during Unilateral Finger Movement with Mirror Visual Feedback
TLDR
It can be concluded that a combination of motor training with MVF therapy may induce more robust neuroplastic changes through multisensory integration that is relevant to motor rehabilitation. Expand
Do Mirror Glasses Have the Same Effect on Brain Activity as a Mirror Box? Evidence from a Functional Magnetic Resonance Imaging Study with Healthy Subjects
TLDR
It is concluded that the mirror glasses might be a promising alternative to the mirror box, as they induce similar patterns of brain activation and can be easy applied in therapy and research. Expand
Movement-Related Cortical Potentials in Embodied Virtual Mirror Visual Feedback
TLDR
Embodied mirror visual feedback is likely to influence bilateral sensorimotor cortical subthreshold activity during movement preparation and execution observed in MRCPs in both healthy participants and a stroke patient. Expand
Neural Processes Underlying Mirror-Induced Visual Illusion: An Activation Likelihood Estimation Meta-Analysis
TLDR
The current meta-analysis is the first to reveal the visualization, mental rehearsal and motor-related processes underpinning the MVI and offers theoretical support on using MVI as a clinical intervention for post-stroke patients. Expand
Network interactions underlying mirror feedback in stroke: A dynamic causal modeling study
TLDR
Dynamic causal modeling was used to test the interactions between regions in the frontal and parietal lobes that may be important for modulating the activation of the ipsilesional motor cortex during mirror visual feedback of unaffected hand movement in stroke patients, and found that mirror feedback-based activation of motor cortex may be attributed to engagement of a contralateral (contralesional) action observation network. Expand
The neuronal correlates of mirror therapy: A functional magnetic resonance imaging study on mirror-induced visual illusions of ankle movements
TLDR
It is concluded that mirror therapy of ankle movements may induce neural activation of the ipsilesional sensorimotor cortex, and that cortical reorganization may be useful for motor rehabilitation in stroke. Expand

Different effects of the mirror illusion on motor and somatosensory processing.
TLDR
The mirror illusion does not elicit immediate changes in motor areas, yet there is a direct effect on somatosensory areas, especially for left hand movements, which suggest different effects of mirror therapy on processing and rehabilitation of motor and sensory function. Expand
Human Motor Plasticity Induced by Mirror Visual Feedback
TLDR
Trans transcranial magnetic stimulation was used to test whether M1 plasticity is a physiological substrate of MVF-induced motor behavioral improvement and indicate that M1 Plasticity, especially in its excitatory connections, is an essential component of MVf-based therapies. Expand
Functional Plasticity Induced by Mirror Training
TLDR
FMRI analysis of action observation and imitation of grasping tasks demonstrated MTr-specific activation changes within the right dorsal and left ventral premotor cortex as well as in the left SMC (SMCleft). Expand
A comparison of neural mechanisms in mirror therapy and movement observation therapy.
TLDR
Lateralized cerebral activations elicited during self-initiated movement mirroring and observation of movements are elicited by inversion of visual feedback (movement mirroring), but not by movement observation. Expand
Effect of a mirror-like illusion on activation in the precuneus assessed with functional near-infrared spectroscopy
TLDR
Findings extend the understanding on interhemispheric rivalry and indicate that a MIR is integrated into visuomotor coordination similar to normal view, irrespective of the hand that is actually performing the task. Expand
Sensorimotor cortex activation during mirror therapy in healthy right-handed subjects: A study with near-infrared spectroscopy
TLDR
The findings suggest that MT is more effective when it is used for dominant right hand movement, and this phenomenon may be the related to the different manipulability between the dominant and non-dominant hands. Expand
The neuronal correlates of mirror therapy: an fMRI study on mirror induced visual illusions in patients with stroke
TLDR
The authors showed that during bimanual movement, the mirror illusion increases activity in the precuneus and the posterior cingulate cortex, areas associated with awareness of the self and spatial attention, which might reduce learnt non-use. Expand
The Potential for Utilizing the “Mirror Neurone System” to Enhance Recovery of the Severely Affected Upper Limb Early after Stroke: A Review and Hypothesis
TLDR
The hypothesis that observation of another’s movement might train the movement execution system of stroke patients who have severe paresis to bring them to the point at which they could actively participate in rehabilitation consisting of goal-directed activities is raised. Expand
Optical illusion alters M1 excitability after mirror therapy: a TMS study.
TLDR
The present study confirms the previous suggestion of the involvement of the "contralesional" left-side (ipsilateral to the hand behind the mirror) M1 after mirror therapy, which is not mediated by IHI. Expand
Mirror, mirror on the wall: viewing a mirror reflection of unilateral hand movements facilitates ipsilateral M1 excitability
TLDR
Findings provide neurophysiological evidence supporting the application of mirror therapy in stroke rehabilitation and interaction of these effects within M1 may account for recent research suggesting improved functional recovery of the impaired arm following stroke by viewing a mirror reflection of movements of the unimpaired arm superimposed over the (unseen) impaired arm.
