What is the primary function of non-elastic tape in sports medicine?

The primary function of non-elastic tape in sports medicine is to restrict abnormal or excessive joint movement. This type of tape is typically rigid and does not stretch, which allows it to provide a stable support system for joints and muscles. By limiting the range of motion in a controlled manner, non-elastic tape helps prevent injuries during physical activity, particularly in cases where a joint may be at risk of being overextended or misaligned. This stabilization is essential in rehabilitation, as it helps protect the injured area while still allowing for some functional movement.

In contrast, options that suggest enhancing flexibility, promoting circulation, or increasing mobility do not align with the characteristics or intended use of non-elastic tape. Instead, those functions are generally associated with other therapeutic modalities or types of tape that allow for elasticity and movement, such as kinesiology tape.
