Which type of stretching is primarily used in injury rehabilitation?

Passive stretching is the correct choice for injury rehabilitation because it involves an external force, such as a therapist, gravity, or a prop, helping to assist the stretch without the individual having to exert their own muscle strength. This method allows muscles to gently elongate and improves flexibility and range of motion while minimizing the risk of further injury. It is particularly useful for recovering from injuries, as it can be performed in a controlled manner that reduces stress on injured tissues.

In contrast, dynamic stretching typically involves movement and is often used as a preparatory technique before physical activity rather than during rehabilitation. Ballistic stretching incorporates bouncing movements and can pose risks, particularly during the recovery phase, since it may lead to overstretching or reinjury. Active stretching requires the individual to engage their muscles for the stretch, which may not be advisable in the early stages of rehabilitation when the focus is on healing. Thus, passive stretching is the safest and most effective option in the context of injury recovery.
