Final answer:
The statement is false; passive movement should not cause pain to the injured athlete, and any movement that does cause pain should be stopped immediately.
Step-by-step explanation:
Passive movement refers to the motion applied to a joint by another person or an external force without the injured individual actively contracting the muscles. When dealing with an athlete's injury, passive movement can help determine the extent of an injury. However, it is essential to respect the pain threshold of the athlete.
According to principle 5, if movement causes pain, the activity should cease, at least until the pain resolves. This respects the body's signaling which is essential for preventing further injury. Regarding the question, the statement would be false based on this principle because one should not move the injured part to the point of pain, even if the athlete is not the one moving it.
