The role of rehabilitation training for swallowing disorders in Parkinson’s disease: The role of rehabilitation training in improving swallowing disorders, on the other hand, is a relatively well-recognized means at home and abroad. Rehabilitation training can effectively reduce complications, maximize the recovery of the patient’s psychological state and swallowing function, and improve the patient’s viability and quality of life. The training of swallowing muscles, including the exercise of respiratory muscle strength (e.g., expiratory muscle strength exercise (EMST)), can improve the swallowing function of patients with Parkinson’s disease. Conscious “coughing” to increase awareness of self-protection of the airway can reduce the occurrence of choking and aspiration. Staging of swallowing action: Ingestion-swallowing is the whole process of food reaching the stomach through the mouth, pharynx and esophagus from the time it is perceived. This process is divided into 5 phases by the position of the food block: the prior phase (cognitive phase), the preparation phase, the oral phase, the pharyngeal phase, and the esophageal phase. The latter 3 correspond to the 3 phases of the oral, pharyngeal, and esophageal phases of the swallowing action. Phase 1 for the oral phase: mainly by the orbicularis oris muscle, bite muscle participation; Phase 2 for the pharyngeal phase: mainly by the tongue muscle, pharyngeal muscle participation; oral muscle group exercises: 1, open mouth guide method: open mouth to the maximum, adhere to 3 seconds X10, do 5 groups 2, bite teeth guide method: lips closed, bite the gums 30 times X5 3, shrink lips breathing exercises: mouth and lips do flute, rapid inhalation 2 seconds. Exhale slowly for 5-6 seconds Tongue movement: stretch the tongue forward, back, left, right, up and down in each direction to do active movement; instruct the patient to try to extend the tongue, respectively lick the lips up, down, left and right. Put some peanut butter or jam on the tongue depressor and ask the patient to lick with the tip of the tongue, with the tip of the tongue against the hard palate, stop for 5S and do the “snap” movement. Pronunciation training: Pronunciation is related to pharynx, using single sound, single word training, through the opening and closing of the mouth, vocal door opening and closing to promote the lips, muscle movement and vocal door closure function. Let the patient inhale deeply and exhale deeply and slowly to make the sound of “ah, clothes, wu”, and pronounce it 10 times in turn; repeat “dad, fight, home, la” 10 times; pharyngeal cold stimulation and empty swallowing training: the patient takes a sitting position, leans forward, and gives a small table if necessary. Give support to the body. Do the following 10 exercises before meals, using cotton swabs dipped in ice water, gently stimulate the soft palate, tongue root and posterior pharyngeal wall, and then do empty swallowing action; repeat the exercises, the number of exercises can be flexible. Put a drop of ice water (0.5 ml) on the patient’s tongue, instruct the patient to do chewing action, and then swallow the water. Feeding training: Position: generally sit in an upright position with the head in the middle position, keep the upper body at 45.-60. with the sitting plane, tilt the neck and head forward slightly, do not lie down to eat. Keep sitting position for at least 0.5 h-1.0 h after eating. Food utensils and food form selection: choose shallow, small spoon, food form according to the degree of swallowing disorder and the stage of eating paste meal a thick porridge a soft rice a broken meal a proper meal. Choose foods that are easy to swallow, have proper viscosity and do not remain on the mucous membrane. Feeding volume: start with 3 ml -5 mL each time, gradually, adjust the feeding speed according to the patient’s eating, chewing and swallowing speed, and must finish swallowing one mouthful before the next ingestion to prevent choking and mis-swallowing. Afterwards, the speed was increased to 10 ml-15 mL per tablespoon as appropriate. The feeding training was performed twice a day for 0.5 h-1.0 h each time. Clinical symptoms were observed: daily observations were made to record the presence of choking and coughing, swallowing and the degree of muddy sound after eating and drinking, the time required for each feeding, the amount of food left in the mouth after feeding, the texture and volume of food eaten each time, and whether or not the patient had choked and swallowed. The amount and texture of food, the presence or absence of increased sputum sounds, rising body temperature and other signs of aspiration pneumonia. If choking occurs, relax the patient, lean forward slightly, spit out the remaining food in the mouth, apply pressure with the palm of the hand under the patient’s sternum, and tell the patient to cough vigorously Note: Do not pat the patient’s back, as this action may lead to aspiration. Analyze the cause of the cough with the patient and try to avoid a recurrence. Treatment in case of asphyxia: In Hemric first aid, the rescuer stands behind the victim, holds his abdomen from behind, surrounds his waist and abdomen with both arms, makes a fist with one hand, presses the fist inward on the area between the victim’s navel and ribs; the other hand becomes a palm covering the fist, squeezes both hands sharply and forcefully inward and upward, repeatedly and forcefully, rhythmically, until the obstruction is spit out. Principle: The use of impact on the abdomen – the soft tissue under the diaphragm, being a sudden impact, generating upward pressure, compressing the lower part of the two lungs, thus driving the residual air in the lungs to form a stream of air. This airflow with impact and directional long drive into the trachea, can be blocked trachea, larynx and other foreign objects such as hard food to drive away, so that people are saved. Heimlich self-help method: If no one is present around the patient in an emergency, self-help method can be used. The patient can use his or her own hand or the back of a chair or table edge against in the upper abdomen, squeeze quickly and violently, and relax immediately after the pressure.
