Split hand syndrome is a potential sign of amyotrophic lateral sclerosis (ALS). This means that some of the muscles in the hand are weak and thin (atrophied), while others are less affected.

Spinal muscular atrophy or “SMA” for short is a terrible disease in which a genetic mutation causes certain nerves responsible for sending signals to muscles to degenerate. This leads to muscles ...

Skeletal muscle atrophy, or wasting, is a devastating and often irreversible syndrome during the aging process and for patients with advanced cancer. Muscle wasting involves a decrease in muscle mass ...

Repeated exercise, or wasting, can change the way key genes work.

Spinal muscular atrophy is a genetically inherited disorder that causes muscle weakness. Adults can get spinal muscular atrophy, but it’s rare in adults and progresses slowly. It doesn’t typically ...

When a limb is rendered immobile for long periods of time, its muscles will inevitably begin to atrophy. A new implant could help keep that from happening, however, by mechanically stretching and ...

Infections can present with many different symptoms, and one common symptom is wasting, which involves the loss of fat and in extreme cases lean muscle as well. Researchers in the lab of Salk ...

Muscles are made to move. Stretching and contraction stimulate biochemical pathways within muscle that maintain tissue health. When movement slows—when a broken limb is immobilized in a cast, for ...

About 80% of people with cancer suffer from significant muscle wasting, or loss of muscle tissue, and 30% of these patients die from this condition. New research in mice finds that the severity of ...
