Which of the following is considered a common musculoskeletal injury?

Back pain is considered a common musculoskeletal injury because it pertains specifically to the muscles, ligaments, tendons, and bones that support the spine and contribute to movement. It is a prevalent condition that affects many individuals at some point in their lives, often resulting from factors such as poor posture, lifting heavy objects incorrectly, or prolonged sedentary behavior.

While headaches, sprained ankles, and asthma are significant health issues, they do not fall primarily under the category of common musculoskeletal injuries. Headaches typically relate to neurologic or vascular factors, or tension-related issues, rather than musculoskeletal problems. A sprained ankle, while a musculoskeletal injury, is less prevalent in comparison to back pain, which is often more widespread and chronic in nature. Asthma is a respiratory condition and does not involve the musculoskeletal system at all. Therefore, back pain represents a key area of focus when discussing musculoskeletal injuries in the context of physical health and exercise intervention.
