What is a contracture?

A contracture is defined as a permanent stiffening or shortening of a muscle or a joint. This condition arises when muscles, tendons, or ligaments become tight and shorten over time, often due to lack of movement, prolonged immobilization, or conditions such as arthritis or muscular dystrophy. This results in limited range of motion in the affected area and can lead to significant functional impairment. Recognizing and addressing contractures early is crucial in patient care to prevent long-term disability and promote mobility.

Understanding contractures and their implications is particularly important for CNAs, as they play a role in assisting patients with mobility and ensuring that their muscles and joints remain flexible. The other options describe conditions or concepts that do not accurately define a contracture, focusing instead on transient conditions or exercises that do not lead to permanent changes in muscle or joint structure.
