AI takes aim at frozen shoulder: smarter injections on the horizon
NCT ID NCT07599059
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study combines artificial intelligence with ultrasound imaging to better understand and treat frozen shoulder (adhesive capsulitis). Researchers will compare three different ultrasound-guided injection techniques in 192 participants to see which one best reduces pain and improves shoulder movement. The goal is to use AI to predict which treatment works best for each person, helping doctors make more personalized decisions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Inclusion Criteria for the Control Group: 1. Age-matched adults (≥ 18 years old) with no symptoms of adhesive capsulitis. 2. Age distribution matched with that of the disease group. * Inclusion Criteria for the Disease Group (Adhesive Capsulitis): 1. Shoulder stiffness persisting for more than one month. 2. Restriction of passive range of motion by more than 30° in at least two of the three directions (forward flexion, abduction, and external rotation) compared to the contralateral side, with imaging findings consistent with the diagnostic features of primary adhesive capsulitis. Exclusion Criteria: * Exclusion Criteria (for both Control and Disease Groups): 1. Systemic rheumatic disease (like rheumatoid arthritis and ankylosing spondylitis). 2. History of malignancy. 3. Previous major trauma, surgeries, or recent injection therapy on the affected shoulder. 4. Suprascapular nerve block within the previous three months. 5. Inability to clearly understand or express personal willingness due to central nervous system injury.
