This short video shows m. latissimus dorsi (Broadest muscle of the back) in the context of “Muscle pain in the back.” A large, flat muscle that covers almost entire lower back. It starts from the thoracic and lumbar vertebrae and attaches to the upper arm bone (humerus). This links the muscle’s location and role in movement with the areas where tension or pain may be felt.
A large, flat muscle that covers almost entire lower back. It starts from the thoracic and lumbar vertebrae and attaches to the upper arm bone (humerus). The clip places this within “Muscle pain in the back” so it is easier to understand what is happening in the area, not only where symptoms are felt.
Muscle pain is not always local. When a muscle is overloaded or lacks control during movement, tension or pain can also be felt in a nearby area.
This is an educational visual linked to “Muscle pain in the back.” If symptoms keep returning, restrict movement, or their source is unclear, a functional assessment is a more useful next step than guessing.
