The inability of hemiplegic patients to extend their fingers is due to the fact that after hemiplegia, the upper motor neurons lose the ability to control limb movement or their ability is weakened, which will result in distal limb inactivity, i.e., inflexible movement of the fingers or feet, such as unsteady walking, deterioration of limb dexterity, e.g., deterioration of finger dexterity, inability to do fine movements such as holding beans with chopsticks or spoons. In some serious large infarction or core infarction, there will be finger contracture and inability to extend, and the muscle tension will become higher over time, and it will be more difficult to extend the fingers. Therefore, it is very necessary to insist on rehabilitation exercise and rehabilitation training in the early stage of infarction, together with the secondary prevention of cerebrovascular disease, to prevent the aggravation of limb immobility.
