The pathogenesis of cerebral infarction is due to the formation of blood clots in the blood vessels, which block the blood flow and lead to ischemia and necrosis of the brain cells in the corresponding areas of the vessels. Physiotherapy apparatus does not have the function of regenerating brain cells, so for patients with mild cerebral infarction, physiotherapy apparatus only plays an auxiliary therapeutic role and will have certain effect, but the effect is not obvious. For patients with severe cerebral infarction, such as patients with muscle strength of grade 0, 1 or 2, physiotherapy instruments are almost ineffective and cannot achieve the purpose of treatment. Therefore, patients cannot fully believe in physiotherapy instruments, the effect is there, but not very obvious. It is recommended that patients should have regular treatment for cerebral infarction and auxiliary treatment with physiotherapy apparatus, which is correct.
