How to determine muscle atrophy?

Muscle diseases are becoming more and more common in life, causing great damage to the health of many people and seriously affecting the living standards of patients. Therefore, muscle diseases need to be diagnosed and treated promptly. Among muscle diseases, muscular atrophy is the most common and has the greatest impact. However, this disease is often difficult to diagnose in the early stages. Let’s take a look at how to determine muscle atrophy.

1. Thigh muscle atrophy: It is common for patients with femoral head necrosis to experience thigh muscle atrophy. The severity of muscle atrophy varies. Most patients with femoral head necrosis can recover from thigh muscle atrophy, but a few patients with femoral head necrosis cannot recover from thigh muscle atrophy throughout their lives, which seriously affects the patient's walking distance and quality of life. 100% of patients with mid-to-late stage femoral head necrosis have varying degrees of thigh muscle atrophy in the affected limb, which has a great impact on the walking of patients with femoral head necrosis, directly limiting the recovery of strength in the affected thigh, and also limiting the length of patients' walking.

2. Calf muscle atrophy: Calf muscle atrophy refers to skeletal muscle dystrophy, in which the muscle volume is smaller than normal, the muscle fibers become thinner or even disappear.

3. Hand muscle atrophy: It is a type of 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.

Mild atrophy: The muscle fibers decrease slightly, there is no obvious depression in the appearance of the muscle tissue, the muscle tissue feels loose to the touch, the muscles are weak, and they can do resistance exercise. Moderate muscular atrophy: Partial atrophy and loss of muscle fibers, concave appearance of muscle tissue, longitudinal shrinkage and lateral reduction when touched, obvious muscle weakness, and inability to do resistance exercises.

Severe muscular atrophy: Most of the muscle fiber tissue is atrophied and the related bones are exposed. Only a small amount of muscle fibers remain in the muscle tissue, the muscles are severely weak, and the patient loses the most basic ability to coordinate movements.

Complete atrophy: Complete atrophy of muscle fiber tissue, with complete loss of motor function associated with the muscle.

4. 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 obvious in the proximal limbs and trunk muscles, and often manifests as atrophy and weakness of the shoulder girdle muscles and pelvic girdle muscles. For example, due to weakness of the neck muscles, some patients need to use their hands to support themselves in order to lift their heads. Atrophy of the scapular muscles results in a winged scapula.
