The recovery of stroke patients is generally divided into four phases: the flaccid phase, also known as the hypotonic phase, the spastic phase, the recovery phase, and the sequelae phase. The symptoms of the flaccid phase mainly include muscle relaxation, low muscle tone, and lack of autonomous movement. The majority of patients maintain the flaccid phase for about one to three weeks, and depending on the individual's condition, they generally begin to enter the spastic phase after one to three weeks. A small portion of patients with severe conditions and poor initiative, who have not undergone formal rehabilitation training, may extend their flaccid phase to more than a month or even longer. Therefore, receiving early formal rehabilitation training to improve muscle strength and spasticity treatment can allow patients to smoothly transition through the flaccid phase and gradually enter the spastic phase. Good management of spasticity is even more beneficial for the patient’s recovery. Rehabilitation training can help stroke patients recover sooner and faster.
