Spasticity is considered a common reaction after injury, death or apoptosis of central nervous system neurons occur. Dr. Aysegul Gunduz, Cerrahpasa School of Medicine, Istanbul University in Turkey, cooperated with Spanish and American scholars summarized the non-invasive brain stimulations mainly consisting of repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS). They reported that rTMS and tDCS can regulate and protect the activities of cerebral motor cortex neurons and improve the symptoms of plasticity caused by injuries to central nervous system or neurons. Their findings were published in Neural Regeneration Research (Vol. 9, No. 7, 2014).
