Final answer:
A strong and painful MSTT most likely indicates a partial tear.
Step-by-step explanation:
An MSTT that is strong and painful would most likely indicate a partial tear.
When a muscle fiber tears partially, it can result in a strong and painful sensation. This is because the muscle fibers are damaged, but not completely severed. In contrast, a complete tear would result in a more severe and debilitating injury.
Examples of partial tears include a partial tear of a muscle tendon (tendonopathy) or a partial tear of a ligament. Both of these injuries can cause pain and impact the normal functioning of the musculoskeletal system.
