Here, the function of daily living refers to the activities that are necessary for a person to maintain daily living, which are necessary for self-care and maintaining health, including mainly the ability to take care of oneself physically (dressing, brushing teeth, walking, washing, and urinating and defecating, etc.) and the basic ability to use daily tools (making phone calls, taking a car, using money, and sweeping the floor, etc.). The ability to use daily tools is generally impaired at first, and then progresses to impairment of somatic self-care. In the early stages of the disorder, patients do not have problems with daily functioning; in the middle stages, the impairment is mainly partial; and in the late stages, there is a complete loss, as if they were infants. The purpose of daily function training: early stage is to maintain the ability of daily living; middle stage is to increase or improve the ability of self-care and strengthen the confidence of independent living; late stage is to restore the basic life functions. Therefore, the training of daily functions should be carried out according to the severity of the disease. For patients who can still take care of themselves in the early stage, we should urge and remind them to take the initiative to complete daily tasks, instead of simply taking care of them, we can also discuss with the patient to develop purposeful and selected homework activities that are useful for promoting daily functions, and set them to be completed regularly every day, which is the so-called “homework”. This is called “homework”. For example, the number of times and time for sweeping, mopping, washing clothes, etc. can be set every day. From simple to complex daily functional training, the patient can maintain a more complete and independent self-care ability. 2.Mid-term patients In addition to the above homework therapy, training can be used to restore some of their lost living ability. Allow the patient sufficient time to complete whatever he is capable of doing independently, and do not limit the time to rush to complete, such as washing face, brushing teeth, combing hair, eating, tidying up the room, doing personal hygiene, etc. Try to let him do as much housework as possible, such as sweeping the floor, wiping the table, etc. You can also do some useful mental activities, such as talking, reading newspapers, watching TV, listening to music, etc. The lost ability of daily life can be trained day after day by reminding, teaching and doing it again and again until it is learned. Patience and enthusiasm should be used during training, never reprimand or even ridicule, so as not to hurt the patient’s self-esteem and refuse future training. 3.Late stage patients These patients’ daily living ability is seriously impaired, and training is difficult. For the few patients who still have basic daily living skills and can still cooperate, training should be started from basic living functions. Repeated long-term training (eating, dressing, walking, brushing teeth, etc.) is required to achieve certain results. For example, the steps of feeding can be divided into three steps: feeding, self-feeding and co-feeding, self-feeding, and then the specific actions of each step can be decomposed and used in training. For example, the spoon with rice is skillfully delivered to the patient’s mouth first, and then to the patient’s mouth, followed by the practice of scooping, holding the spoon and other actions. When the whole feeding procedure is proficient, then we can learn it systematically in the opposite way, i.e., hold the spoon, scoop the rice in the bowl, deliver the spoon with rice to the patient’s mouth, and then deliver it to the mouth. Similarly, the procedures for training the patient to urinate and defecate are: (1) Tell the patient to go to the toilet or spittoon to relieve himself; (2) Take the patient to the toilet or ask him to urinate and defecate on the spittoon; (3) After passing the above procedures, the patient may urinate and defecate in the toilet or spittoon; (4) Let the patient go to the toilet or sit on the spittoon completely by himself and be able to urinate and defecate independently; (5) Be able to keep from wetting the bed while sleeping.
