Final answer:
It is false to 'walk off' a sprained ankle as it could worsen the injury. A high ankle sprain affects the syndesmotic joint, and treatment should follow the RICE technique, not exertion which can cause further harm.
Step-by-step explanation:
False. It is not advised to "walk off" a sprained ankle. A sprain occurs when ligaments are overstretched or torn, and walking on it can exacerbate the injury. For a high ankle sprain, which affects the ligaments connecting the tibia and fibula, the involved joint is syndesmotic, not a ball and socket joint. Therefore, walking could worsen the sprain.
To clarify, a sprain is not a tear in the muscle fibers; it's a ligament injury. Conditions like a stroke can directly damage neurons, not muscles.
For an ankle sprain, it's imperative to follow the RICE technique: Rest, Ice, Compression, and Elevation. In the case of severe injuries, medical intervention might be necessary, e.g., using a brace, cast, or even surgery if there's a ligament tear or bone fracture.
