» Abstract |
Mirror
therapy (MT) is a valuable method for enhancing motor recovery in
poststroke hemiparesis. The technique utilizes the mirror-illusion
created by the movement of sound limb that is perceived as the paretic
limb. MT is a simple and economical technique than can stimulate the
brain noninvasively. The intervention unquestionably has neural
foundation. But the underlying neural mechanisms inducing motor recovery
are still unclear. In this review, the neural-modulation due to MT has
been explored. Multiple areas of the brain such as the occipital lobe,
dorsal frontal area and corpus callosum are involved during the simple
MT regime. Bilateral premotor cortex, primary motor cortex, primary
somatosensory cortex, and cerebellum also get reorganized to enhance the
function of the damaged brain. The motor areas of the lesioned
hemisphere receive visuo-motor processing information through the
parieto-occipital lobe. The damaged motor cortex responds variably to
the MT and may augment true motor recovery. Mirror neurons may also play
a possible role in the cortico-stimulatory mechanisms occurring due to
the MT.
