1. Why should patients with polymyositis/dermatomyositis eat a high-protein diet? A: For patients with polymyositis/dermatomyositis, a high-protein diet should be given in order to maintain strength and restore muscle power as soon as possible. Such as more fish, lean meat, eggs, etc., can also add one egg and one or two lean meats daily on top of the three meals. 2.Why should patients with polymyositis/dermatomyositis eat more foods high in fiber? A: Patients with poly/dermatomyositis often have smooth muscle involvement in the digestive tract and slowed intestinal motility. The anal sphincter is diseased and the normal bowel function is impaired, resulting in stool retention. So eat a high-fiber diet, such as leeks, celery, soy milk, carrots and other vegetables and fruits, which can prevent dry stools. 3.What foods can not be eaten by patients with polymyositis/dermatomyositis? A: Patients with polymyositis should abstain from eating oily, spicy, cold, hard and other stimulating foods, quit smoking and alcohol. Eat less sea fish, shrimp, crab and other seafood that can cause allergies. Various vegetables and meat in food should be chopped as much as possible. Take easy-to-digest thin and soft food as appropriate. Eating speed should be slow to prevent choking into the trachea. 4.What should be noted in the diet of patients with poly/dermatomyositis when they have choking and swallowing difficulties? A: The disease often invades the muscles of the pharynx, causing swallowing difficulties. When eating, patients will have symptoms such as no choking and difficulty in swallowing. To prevent aspiration, patients should sit or semi-sit when eating, and give semi-liquid diet, such as soft noodles, thin rice, rice soup, sesame paste, etc., because it is easy to form food mass for swallowing. Eat a variety of vegetables and fruits, meat should be chopped, do not eat hard, greasy, spicy and stimulating food. It is advisable to have a small number of meals, the speed of eating should not be too fast, to slow, small mouth to eat, to prevent choking into the trachea. 5.Can patients with polymyositis regain their self-care ability soon? A: Polymyositis is a chronic and progressive disease with a good prognosis, tending to recover in 2-3 years, and the duration and severity of the disease is related to the prognosis. The application of hormone therapy takes about 1 – 6 months from the start of medication to the maximum improvement of the disease, usually 2 – 3 months. Therefore, they cannot recover quickly. Patients should understand the general knowledge of the disease, establish confidence in the treatment, actively cooperate and start to resume activities after the symptoms are relieved so that they can resume self-care as soon as possible. 6.How can patients with polymyositis/dermatomyositis maintain muscle strength? A: Patients with dermatomyositis should rest absolutely in bed during the acute phase and reduce activities to avoid or aggravate muscle damage. Pay attention to turning and patting the back to promote the elimination of sputum and prevent the occurrence of crushing pneumonia. Also strengthen skin care to prevent various infections. After muscle strength starts to recover, encourage and assist patients to perform muscle strength exercises, first give passive limb movements, then let patients do active limb movements, and do a good job of helping to prevent over-activity or falls due to muscle weakness. 7. What are the principles and methods of functional exercise for patients with multiple/dermatomyositis? A: In the acute stage should be absolute bed rest, avoid activities, so as not to aggravate the symptoms of dermatomyositis. After the symptoms are reduced, the patient should be encouraged to perform appropriate passive or active activities in bed, such as limb extension and flexion, lifting arms, lifting legs, holding objects and swallowing to prevent muscle contracture; if the condition further improves, the amount of activity can be increased appropriately, such as walking beside the bed with the support of family members, walking out of bed on their own, walking, going to the toilet, going up and down stairs or playing tai chi and other exercises. 8.Patients with polymyositis / dermatomyositis muscle strength has not fully recovered, what to pay attention to when the activity? A: Patients should not be in a hurry when doing exercise, but should be gradual and persistent, gradually increasing the intensity and time of exercise to reduce muscle atrophy. Activities must be protected to prevent falls. Gradually increase the amount of activity to the next day does not feel fatigue is appropriate, do not strenuous exercise. It can also be combined with massage, massage, hydrotherapy, diathermy and other physical methods to prevent muscle atrophy and contracture.
