What is a likely result for someone who has been immobilized in a cast for six weeks?

When someone has been immobilized in a cast for six weeks, muscle atrophy is a likely result due to the lack of movement and muscle use during that period. Atrophy refers to the reduction in muscle size and strength that occurs when muscles are not engaged in regular activity. The immobilization caused by the cast limits the ability to perform normal movements and activities, leading to a decrease in muscle mass as the body does not need to maintain muscle tissue that is not being used.

This process occurs because muscles rely on regular stimulation through exercise and movement to maintain their size and strength. Without this stimulation, the body begins to break down muscle fibers to conserve energy, which manifests as atrophy. It is an expected physiological response in individuals who are recovering from injuries or surgeries that require immobilization. Understanding this helps emphasize the importance of rehabilitation and gradual reintroduction of movement once the cast is removed to restore muscle strength and function.
