Transcranial electrical stimulation may help speed recovery of stroke patients

Stroke is also known as stroke or cerebrovascular accident. There are 70 million stroke patients in my country, 2 million new strokes every year, and 1.65 million stroke deaths every year. Every 12 seconds, one Chinese has a stroke. In 21 seconds, one Chinese person dies of a stroke, and the Chinese people who die from stroke each year account for 22.45% of all deaths.


Traditional rehabilitation therapy


Stroke can lead to sequelae such as hemiplegia, aphasia, dysphagia, and cognitive impairment, which seriously affect the quality of life of patients. Some patients can return to work after rehabilitation treatment, and many patients still need to be taken care of by others after rehabilitation treatment, causing a serious economic burden to the family and society.


Traditional rehabilitation therapy


Traditional rehabilitation therapy mainly trains limbs, speech, and swallowing functions. Plastic changes in brain function are induced by these rehabilitation exercises and further improve the injured function. In recent years, studies have found that, in addition to traditional training that can change brain function and improve the dysfunction of stroke patients, non-invasive neuromodulation of the brain, such as transcranial direct current stimulation technology, can directly regulate the excitability of the cerebral cortex, and then more effectively improve. Rehabilitation treatment prognosis.

Transcranial direct current stimulation is a non-invasive brain function regulation technology, which has its unique advantages in stroke rehabilitation. Electrical stimulation can improve cerebral blood flow and brain metabolism, regulate ion balance, affect the transmission of various neurotransmitters and amino acid metabolism in the brain, produce long-term enhanced plastic changes, promote synaptic connection function, and regulate local Cortex and brain network connections.


In recent years, the application of transcranial direct current stimulation in stroke rehabilitation has gradually increased, including motor dysfunction, cognitive dysfunction, disturbance of consciousness, aphasia, swallowing dysfunction, cerebellar ataxia, depression, and so on. A large number of clinical applications and studies have shown that transcranial direct current stimulation can effectively promote the effect of traditional rehabilitation therapy and become an accelerator for rehabilitation therapy.



The Department of Rehabilitation Medicine of Beijing Tsinghua Chang Gung Memorial Hospital has carried out transcranial direct current stimulation technology in the rehabilitation treatment of nearly 100 stroke patients. Clinical application found that the early development of this technology after stroke can significantly improve the prognosis of stroke patients and improve the efficiency of rehabilitation treatment. Its treatment safety is high, there are no adverse reactions such as epilepsy, and the treatment effect has been recognized by the majority of patients.

Attention: Although transcranial direct current simulation technology has a very broad application prospect in stroke rehabilitation, experts advise stroke patients that this technology needs to be treated under the guidance of professionals. Due to different factors such as lesion location, lesion size, and course of the disease, choosing an appropriate neuromodulation site and regulating the dose is the key to determining the success of treatment. In addition, transcranial direct current stimulation treatment also needs to cooperate with the correct rehabilitation treatment plan in order to achieve the ideal rehabilitation effect.
