Final answer:
When patients don't use their lower extremity, they are at risk for muscle atrophy, decreased bone density, and reduced circulation.
Step-by-step explanation:
When patients don't use their lower extremity, they are at risk for various health problems and complications. One of the primary risks is muscle atrophy, which is the wasting away or loss of muscle mass. Without regular use and movement, the muscles in the legs can become weak and small.
Additionally, lack of use can lead to decreased bone density and increased risk of fractures. Weight-bearing exercise, such as walking or jogging, helps to maintain bone health. Without this activity, bones can become weaker and more prone to breakage.
Furthermore, not using the lower extremity can result in reduced circulation and increased risk of blood clots. Movement helps to keep blood flowing and prevents the formation of clots. Immobility can lead to stagnant blood flow and the development of dangerous blood clots.
