Which of the following best describes a contracture?

A contracture is characterized by the lack of joint mobility due to the shortening of a muscle. This typically occurs when there is a prolonged period of immobility, often seen in individuals who have had a stroke, prolonged bed rest, or other conditions that limit movement. When a muscle becomes shortened and tight, it can restrict the normal range of motion of the joint it serves, leading to discomfort and functional limitations.

Understanding contractures in this way highlights the importance of maintaining mobility and implementing regular stretching and strengthening exercises in patient care, especially for those at risk of developing contractures due to inactivity or immobilization. This knowledge is crucial for nurses and healthcare providers to help prevent or manage contractures in patients effectively.
