It is false that hemiplegia is cured in 3 days, and there is no scientific basis for this claim. The recovery time of hemiplegia is related to the degree of hemiplegia, the primary disease and the effect of rehabilitation treatment. If the degree of hemiplegia is not serious, the patient can be treated in the acute stage and recovered quickly after effective rehabilitation treatment at a later stage. If the patient’s hemiplegia is very severe, with zero muscle strength at the onset of hemiplegia, he/she is unable to move at all, and is likely to suffer from after-effects of hemiplegia. Active rehabilitation exercises can effectively help the recovery of hemiplegia. For the accompanying primary diseases, if timely and targeted treatment can be carried out, and at the same time in daily life need to strictly control the blood pressure, blood sugar and all kinds of chronic diseases can also effectively promote the recovery of hemiplegia. Meanwhile, when the patient’s condition is stabilized and there is no progressive aggravation, rehabilitation therapy should be carried out as soon as possible, including muscle strength training, joint activity training, balance training, gait training and daily living ability training, etc., which can effectively improve the prognosis of the patient. It is recommended that hemiplegic patients should receive standardized treatment and scientific training under the guidance of doctors as soon as possible to avoid delaying their condition.
