What is progressive muscular atrophy

summary

In orthopedic diseases, the high incidence of muscle atrophy is very common, muscle atrophy for muscle tissue damage is also huge. So, what is muscle atrophy? Next, I'll give you a brief introduction.

What is progressive muscular atrophy

First, patients with muscle atrophy may often have fascicular fibrillation, which is caused by lower motor neurons and their damage. When the anterior horn cells and brainstem motor nuclei are damaged, muscle atrophy presents segmental distribution. The main symptoms of muscle atrophy are the distal limbs, symmetrical or asymmetric, without sensory disturbance. This is a common symptom of muscle atrophy. If the EMG examination, can find muscle atrophy thinning, microscopically showed bundle atrophy changes.

Second: the symptoms of myogenic atrophy are often manifested as symmetric atrophy of proximal pelvic belt and scapular belt. As the phenomenon of muscle weakness is more and more obvious, patients with muscle atrophy often have no muscle fiber tremor and sensory disturbance.

Third: lower limb flaccidity and weakness, can not stand for a long time, lumbar spine soreness. Unilateral or bilateral sensory disturbance or pain disappeared. And accompanied by dizziness, tinnitus, spermatorrhea, enuresis or irregular menstruation, red tongue less moss, pulse count. This is a symptom of muscle atrophy.

matters needing attention

Fibrillation is also one of the symptoms of muscle atrophy. Muscle fibrillation can be induced by tapping the atrophic muscle with the thumb. Its size is directly proportional to the extent of lesion and the length of muscle fiber. The appearance of muscle fibrillation often indicates motor neuron lesion.
