A positive Doppler signal on tendons (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.002) and absent tendon heterogeneity (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.01) were associated with the patient's self\u2010reported improvement.

A reduction in the number of calcifications (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.004), in the supraspinatus tendon thickness (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.01), in subacromial effusions (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.03), and in color Doppler grade (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.02), between initial and follow\u2010up exams, was found in patients with an improved DASH outcome.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A positive Doppler signal on shoulder tendons can be a marker for a better prognosis in shoulder pain.
