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.

HOUSTON – A newly identified gene, atrogin-1, is involved in muscle loss associated with cancer, diabetes, fasting and kidney disease as well as in the atrophy occurring with disuse, inactivity, and ...

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 ...

Muscle loss (atrophy) due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging. New research published in Advanced Science shows that ...

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 ...
