Summary

This study compared shoulder muscle strength and fatigue between 60 people with frozen shoulder (adhesive capsulitis) in the recovery phase and healthy individuals. Researchers used a special machine to measure peak torque and fatigue index of shoulder muscles. The goal was to understand how frozen shoulder affects muscle function, not to test a treatment.

Who is studied

In the present study, 60 participants between 40 and 60 years were recruited. They were enrolled in the experimental group, which included 30 typical subjects with unilateral AC and the control group (dominant shoulder) that included 30 healthy individuals of the same age and sex. Individuals were recruited from the outpatient clinics and respective orthopedic centers. They were informed through an advertisement poster placed on the bulletin of the mentioned locations and referred from a physician.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: The AC group included participants that met the following criteria, based on a previous study conducted by Ramirez \[2\] : 1. clinical diagnosis of unilateral AC by an orthopedic specialist, with the limitation of both active and passive glenohumeral ROM, exceeding 25% in at least two of the following planes: flexion, abduction, and external rotation 2. symptom duration between 3 and 12 months 3. no prior surgery to the involved shoulder 4. age between 40 and 60 years. -The control group consisted of healthy individuals of comparable age and sex distribution with no history of shoulder pain, injury, or pathology Exclusion Criteria: 1. history of shoulder fracture, dislocation, or surgery; 2. corticosteroid or muscle relaxant use within the previous three months 3. cardiovascular or respiratory conditions that could limit physical testing 4. concurrent participation in structured shoulder strengthening programs 5. inability to perform the isokinetic assessment protocol safely 6. systemic musculoskeletal, neurological or rheumatologic disorders, such as diabetes mellitus, rheumatoid arthritis and cervical radiculopathy. Individuals with diabetes mellitus were excluded due to its well-established association with AC.
