Sarcopenia (ICD-10-CM code M62.84 [1]) is a type of muscle loss that occurs with aging and/or immobility. It is characterized by the degenerative loss of skeletal muscle mass, quality, and strength. The rate of muscle loss is dependent on exercise level, co-morbidities, nutrition and other factors.
Beevor’s sign is characteristic of spinal cord injury between T9 and T10 levels. [3] The sign has also been observed in amyotrophic lateral sclerosis, a disease causing progressive weakening of the muscles of multiple areas of the body, and in facioscapulohumeral muscular dystrophy (FSHD), a disease named after areas of the body it preferentially weakens (face, shoulder, and upper arm).
Muscle weakness can also be classified as either "proximal" or "distal" based on the location of the muscles that it affects. Proximal muscle weakness affects muscles closest to the body's midline, while distal muscle weakness affects muscles further out on the limbs. Proximal muscle weakness can be seen in Cushing's syndrome [18] and ...
Weakness is a symptom of many different medical conditions. [1] The causes are many and can be divided into conditions that have true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy.
Muscle stiffness may also be present; if muscle weakness is not also present, and cramps are more severe, the stiffness may be categorized instead as cramp fasciculation syndrome. [3] Cramp fasciculation is a variant of BFS which presents with muscle pain and exercise intolerance. [2] [4]
Additional causes can be attributed to excessive abdominal exercises after the first trimester of pregnancy. [4] Strength training of all the core muscles, including the abdominis recti muscle, may reduce the size of the gap in pregnant or postpartum women. Crunches may increase the diastasis recti separation. All corrective exercises should be ...
A Spigelian hernia is the type of ventral hernia that occurs through the Spigelian aponeurosis, which is the part of the aponeurosis of the transverse abdominal muscle bounded by the linea semilunaris (or Spigelian line) laterally and the lateral edge of the rectus abdominis muscle medially.

Amongst patients admitted to intensive care units (ICUs), hypoalbuminemia is specifically associated with ICU-acquired muscle weakness. [14] In chronic kidney disease , hypoalbuminemia is an indicator of frailty , which is itself associated with complications, mental distress , quality of life impairment, resource utilization, and mortality.
