What causes deltoid muscle atrophy?

Everyone is familiar with muscle atrophy in life. Deltoid muscle atrophy will not only cause physical harm to the patient, but also cause huge psychological trauma to the patient. What is the cause of deltoid muscle atrophy? Muscular atrophy refers to the reduction in muscle volume caused by nutritional disorders of skeletal muscles, thinning or even disappearance of muscle fibers, etc. The main causes include neurogenic muscular atrophy, myogenic muscular atrophy, disuse muscular atrophy and muscular atrophy due to other reasons.

1. What causes muscle atrophy?

Amyotrophic lateral sclerosis

The first symptoms of this progressive disease are muscle weakness and atrophy. Muscle weakness and atrophy begin in one hand, spread to the upper limb, and then develop to the other hand and upper limb. Eventually, muscle weakness and atrophy spread to the trunk, neck, tongue, larynx, pharynx, and lower extremities; progressive respiratory muscle weakness leads to respiratory insufficiency. Other manifestations include flaccidity, fasciculations, hyperreflexia, mild leg cramps, dysphagia, dysphasia, excessive salivation, and depression. What causes muscle atrophy?

burn

In severe burns, fibrous scar tissue, pain, and loss of serum proteins can restrict muscle activity and lead to muscle atrophy.

Compartment syndrome and Volkmann's ischemic contracture

In this acute disease, muscle atrophy is a late sign of irreversible ischemia, accompanied by muscle contracture, paralysis, and pulselessness. Early symptoms and signs include severe pain, pain that worsens with passive muscle movement, accompanied by weakness and paresthesias.

2. Examination items for muscle atrophy

Electromyography (EMG). Nerve conduction velocity, including motor nerve conduction velocity, sensory nerve conduction velocity, F wave, and H reflex. Evoked potentials: including brainstem auditory evoked potentials, visual evoked potentials, and upper and lower limb sensory evoked potentials. Manual muscle strength test. Muscle tone test. Muscle circumference measurement.

3. Clinical manifestations of muscle atrophy

Thigh muscle atrophy

Atrophy of the thigh muscles is mainly caused by quadriceps femoris. It is a common phenomenon in patients with femoral head necrosis and lower limb immobilization. The severity of muscle atrophy varies. Most disuse-related thigh muscle atrophy can be recovered, which seriously affects the patient's walking distance and quality of life.

Calf muscle atrophy

It refers to skeletal muscle dystrophy, in which the muscle volume is smaller than normal, and the muscle fibers become thinner or even disappear.

Shoulder girdle muscle atrophy

It is the symptom and clinical manifestation of progressive proximal muscular atrophy of the limbs. Progressive proximal muscular atrophy of the limbs is often myogenic atrophy, which is more obvious in the proximal limbs and trunk muscles, and often manifests as atrophy and weakness of the shoulder girdle muscles and pelvic girdle muscles.

By massaging the acupoint, you can take measures to prevent facial muscle atrophy. This point is located in the depression of the infraorbital foramen, directly below the pupil. Pinch the Sibai point with your index finger, gradually applying pressure while pinching. Last for 1 to 2 minutes.

2. Rub the cheek car point and Dicang point with your palm:

Different methods of preventing facial muscle atrophy can help people stay away from the harm of the disease. Press the thenar muscle of the same hand against the cheek-cartilage point (massage muscle) on the affected side, and move to the Dicang point (0.5 cm away from the corner of the mouth) while rubbing, and repeat 50 times.

3. Pay attention to moderate exercise:

Patients should participate in moderate exercise to exercise their bodies and enhance their physical fitness, but they should not exercise excessively. If patients exercise excessively, their condition will worsen. People should choose appropriate exercise according to their own conditions to restore muscle health. In addition, patients with more serious conditions or those who are bedridden should be given appropriate massage to prevent the occurrence of bedsores.
