Ninety patients diagnosed with ALS were selected for detailed clinical examination and skeletal muscle pathology analysis. The results showed that the average age of ALS patients was 54.5 years, with a male-to-female ratio of 3:2. The main clinical symptoms were progressive limb weakness and muscle atrophy, predominantly in the upper and lower limbs. Electrophysiological examinations showed abnormal muscle electrical activity and slow nerve-muscle conduction. Skeletal muscle pathology analysis showed that there were many neurodegenerative phenomena in the muscle fibers of ALS patients, such as decreased neuron volume, irregular size and shape. In addition, there were muscle atrophy and fiber degeneration and necrosis. The results of this study indicate that the skeletal muscle histopathological characteristics of ALS are related to clinical manifestations and provide a certain theoretical basis for the diagnosis and treatment of ALS.Keywords: amyotrophic lateral sclerosis; clinical manifestations; skeletal muscle pathology.
