Cerebral infarction, commonly known as ischemic stroke, has a high mortality rate and causes severe damage to nervous cells in the brain owing to the loss of oxygen, which results in limiting body movements. Several technologies, including physiotherapy and brain stimulation techniques, are being developed and tested for the rehabilitation of brain nervous cells damaged by a stroke. In particular, low-intensity focused ultrasound is expected to be effective for rehabilitating neurological diseases such as stroke, as it can excite or inhibit nerve cells by delivering mechanical energy with high precision at the desired position, while ultrasound is penetrating the cranium without requiring a surgical operation.
