Key result
Reductions in axillary recess thickness strongly correlate with clinical impairments in adhesive capsulitis.
Why the study?
Ultrasound measurements of rotator interval and axillary recess thickening were suggested as specific indicators of adhesive capsulitis, prompting evaluation of sequential ultrasound changes and their correlation with clinical impairments.
Does the thickness of the axillary recess measured by ultrasound correlate with clinical impairments in patients with adhesive capsulitis?
Observational (n=56)
Does the thickness of the axillary recess measured by ultrasound correlate with clinical impairments in patients with adhesive capsulitis?
Ultrasound measurement of axillary recess thickness correlates with clinical impairments and may serve as a useful surrogate marker in patients with adhesive capsulitis.
AR thickness tracks clinical recovery over 6 months; leaves open whether serial ultrasound monitoring adds value beyond clinical assessment.
Recently, ultrasound measurements of the shoulder such as thickening of the rotator interval (RI) and the axillary recess (AR) are suggested as specific indicators of adhesive capsulitis. Herein, we evaluated the sequential changes in ultrasound parameters and clinical impairments and the correlation between the two in the case of adhesive capsulitis through a prospective observational study of 56 patients with adhesive capsulitis. Clinical assessments and ultrasound parameters, including the thicknesses of the RI and AR, were surveyed at baseline and after 1, 3, and 6 months. In 56 patients with adhesive capsulitis, the thickness of the AR significantly decreased at each follow-up evaluation, but the thickness of the RI showed a significant decrease only between the baseline and 1-month evaluation. In repeated analyses of correlation, the thickness of the AR was strongly correlated with all clinical impairments except the pain at rest and range of internal rotation in the affected shoulder. The thickness of AR was correlated with clinical impairments in patients with adhesive capsulitis during the 6 months follow up and could be useful as a surrogate marker in patients with adhesive capsulitis.

Lee et al. (2022) conducted an observational in Adhesive capsulitis (n=56). Ultrasound parameters (thickness of the rotator interval and axillary recess) was evaluated on Sequential changes in ultrasound parameters and clinical impairments and their correlation. In 56 patients with adhesive capsulitis followed for 6 months, axillary recess thickness significantly decreased and strongly correlated with most clinical impairments.
