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.

Muscle atrophy is a primary characteristic of both sarcopenia and cachexia, significantly impacting physical function and quality of life. This figure illustrates the multifaceted causes of muscle ...

Recently, I wrote a column about my battle with carpal tunnel syndrome, and my subsequent surgery. A big problem with a hand and wrist injury is that you can’t grip anything or exert any appreciable ...

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 ...

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 ...

As we age, our muscles atrophy. Earlier this year, researchers found that hepatocyte growth factor (HGF), a protein critical in skeletal muscle development loses its functionality due to nitration as ...

Spinal bulbar muscular atrophy (SBMA) causes a loss of motor neurons in the spinal cord and brainstem. It mainly affects facial and swallowing muscles and the muscles in the arms and legs. Previously, ...

With the intensification of global population aging, muscle atrophy, characterized by the loss of muscle mass and function, has become an important health issue affecting the elderly. Researchers have ...

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 ...
