What is a possible complication of a sprained ankle?

1. Increased range of motion

2. Chronic instability

3. Decreased swelling

4. Improved strength

The correct answer is: Chronic instability

A sprained ankle can lead to chronic instability, which occurs when the ligaments that support the ankle joint are stretched or torn. This instability may manifest as a feeling of the ankle giving way, particularly during activities that involve running, jumping, or pivoting. Over time, this can result in recurrent sprains or prolonged discomfort, affecting the individual's ability to participate in sports or daily activities. The development of chronic instability is a significant concern, as it can lead to further injury if not properly managed and rehabilitated. Effective rehabilitation programs focus on strengthening the surrounding muscles, improving proprioception, and enhancing overall balance to minimize the risk of future injuries. In contrast, increased range of motion, decreased swelling, or improved strength are not typically seen as complications of a sprained ankle. Rather, these outcomes are generally associated with proper rehabilitation and recovery from the injury. Thus, chronic instability stands out as a serious complication related to improper healing or inadequate support following an ankle sprain.
