What is muscular dystrophy and what is muscle dystrophy?

Amyotrophy refers to the visible atrophy of the overall volume of muscles due to various reasons, which is caused by the decrease in the number or volume of muscle fibers, therefore, muscular dystrophy is not a disease, but a clinical symptom.

Amyotrophic diseases can be divided into three categories: neurogenic amyotrophia, myogenic amyotrophia, and disuse amyotrophia. Neurogenic amyotrophic disease mainly refers to the amyotrophy caused by lower motor neuron damage caused by various reasons, and lower motor neuron disease mainly refers to the damage of lower motor neurons such as anterior horn cells and peripheral nerves of the spinal cord, especially the muscle atrophy caused by anterior horn cell damage usually progresses rapidly, such as polio, amyotrophic lateral sclerosis, etc.

Myogenic amyotrophy refers to muscular atrophy due to a lesion of skeletal muscle itself, such as progressive muscular dystrophy. Disuse amyotrophy refers to amyotrophy caused by limb paralysis, long-term bed rest, and reduced exercise caused by various reasons, and mostly involves disused limbs. Different types of amyotrophy have different clinical manifestations, signs, auxiliary examination results, ** methods and prognosis.

Muscle atrophy**:

1. Standardized exercise**: For limb movement disorders caused by muscle atrophy, patients can significantly reduce or alleviate the sequelae of paralysis through regular exercise**. The coordination between the patient's range of motion, muscle tone and antagonism should not be neglected, so as to prevent the patient's muscle strength from returning to normal but also having abnormal movement patterns;

2. Emphasize muscle coordination training: improper muscle strength training can aggravate spasms, and appropriate training can relieve spasms, so that limb movements tend to be coordinated.

The risk of muscle atrophy is related to many factors, such as neurological diseases or muscle damage to the muscles themselves, such as trauma. It is more common in people who are bedridden and overexercised, or in patients with progressive malnutrition and motor neuron disease. Diseases such as lumbar disc herniation and anorexia can also induce this disease.

1. Genetic factors: It usually occurs in adolescents, also known as pseudohypertrophic muscular dystrophy. At present, there is no targeted method, and there is a certain danger that will endanger life.

2. Nervous system diseases: generally polio, cerebral infarction and other diseases, neuropathy causes nerve conduction disorders, resulting in the disuse of some muscle fibers, weakened exercise ability and muscle atrophy.

3. Trauma: When traumatized, you may stay in bed for a long time**, and your muscles will atrophy if you don't move for a long time. In addition, if the spinal cord is damaged due to a fracture, the nerve compression may also cause muscle atrophy.

4. Motor neuron disease: It is a series of chronic progressive neurodegenerative diseases with more than or lower motor neuron damage as the prominent manifestation.

5. Other diseases: such as lumbar disc herniation, cervical spondylosis, malnutrition, Cushing's syndrome, myositis and other diseases, can also cause muscle atrophy.
