What is a key characteristic of a functional knee brace?

A functional knee brace is specifically designed to provide support during activities that require movement and joint stability, such as sports or exercises. Its primary purpose is to assist individuals who may have experienced knee injuries or are at risk of injury while still allowing for a range of motion necessary for those activities. This support helps to minimize the risk of further injury and can enhance confidence in individuals when performing functional tasks.

While the other options describe characteristics that do not align with the primary function of a functional knee brace, this aspect of support during functional activities sets it apart from braces that might be more restrictive or solely for injury prevention. The focus on active use emphasizes the importance of maintaining mobility and function while safeguarding the knee joint.
