Immobilization leads to significant changes in muscle tissue, primarily resulting in atrophy and fatty infiltration. When a muscle is immobilized, it is not subjected to the usual stresses required for maintenance of size and function. As a result, muscle fibers decrease in diameter and the overall muscle mass diminishes, a process known as atrophy. This loss of muscle strength and mass can begin within just a few days of immobilization.

Furthermore, during periods of disuse, the muscle tissue can begin to become infiltrated with fat cells, a phenomenon termed fatty infiltration. This occurs as muscle fibers degenerate and the body replaces some of the muscle tissue with fat, leading to a further decrease in muscle functionality. Altogether, these changes can negatively impact both the strength and endurance of the muscle, making the effects of immobilization particularly detrimental to physical performance and rehabilitation outcomes. Understanding these effects is crucial in developing effective rehabilitation protocols for individuals who have experienced immobilization due to injury or surgery.
