What this research studies

From a patient point of view, researchers will measure how your shoulder moves using precise biplane x‑ray imaging to look for impingement during motion. They will use shear wave elastography and other imaging to characterize tendon degeneration. The team will first create a multivariable model using people without symptoms, then expand it with more asymptomatic participants and later include people who have shoulder pain or tears. The goal is to separate the roles of extrinsic motion, intrinsic tendon changes, and overuse in causing rotator cuff problems.

Who could benefit from this research

Good fit: Adults both without shoulder symptoms and those with shoulder pain or suspected rotator cuff degeneration or tears could be eligible, especially older adults at higher risk.

Not a fit: People needing immediate surgical repair for an acute tear or those unable or unwilling to undergo imaging tests would likely receive no direct benefit from participating.

Why it matters

Potential benefit: If successful, this could help doctors identify why a person’s rotator cuff is failing and guide better prevention or targeted treatment strategies.

How similar studies have performed: Animal studies have supported roles for impingement, degeneration, and overuse, but applying combined human biplane x‑ray and shear wave elastography models is novel and not yet proven in people.
