Ultrasound findings and prognosis of shoulder pain: a role for Doppler signal?
| Summary: | Purpose: To find ultrasound prognostic factors for shoulder pain. Methods: This was an observational, prospective study, comparing the evolution of ultrasound findings with clinical outcomes, in patients with shoulder pain. Data were collected in two appointments, from February 2018 to March 2021. Two-tailed non-parametric statistics were used, and p values <0.05 were considered significant. Results: A total of 79 participants were included in this study (median age 59 years, range 24-70, 61 women). A positive Doppler signal on tendons (p = 0.002) and absent tendon heterogeneity (p = 0.01) were associated with the patient's self-reported improvement. Tendon calcifications with poorly defined contours (p = 0.03) and sparse distribution (p = 0.001) were associated with VAS improvement. A reduction in the number of calcifications (p = 0.004), in the supraspinatus tendon thickness (p = 0.01), in subacromial effusions (p = 0.03), and in color Doppler grade (p = 0.02), between initial and follow-up exams, was found in patients with an improved DASH outcome. Conclusion: A positive Doppler signal on shoulder tendons can be a marker for a better prognosis in shoulder pain. Poorly defined and sparsely distributed calcifications can also indicate a better course of the disease. |
