Short Summary of Main Findings In this 2022 medRxiv preprint, baseline shoulder range of motion (particularly external rotation and abduction) significantly predicted patient-reported outcome measures (PROMs, such as pain and disability scores) in patients with frozen shoulder treated with corticosteroid injections plus rehabilitation. Patients with less severe ROM restrictions at baseline showed greater improvements and better final PROM scores after treatment. The work supports using initial ROM assessment as a simple, objective prognostic tool.
How This Work Has Moved the Field Forward It adds evidence that baseline impairment level can help forecast treatment response in a common conservative protocol (injection + physio), aiding clinicians in setting realistic expectations, triaging patients, and personalizing rehab plans. It reinforces the prognostic value of ROM over other factors in non-operative frozen shoulder management.
Major Issues
Remains an unreviewed preprint (no peer-reviewed journal version identified as of 2026).
Small sample size and lack of control group limit generalizability and causal inference.
Potential selection bias and short or unclear follow-up duration.
Minor Issues
Title has grammatical error (“predict” should be “predicts”).
Limited detail on exact statistical models or effect sizes in available summaries.
Unclear reporting of confounders (e.g., diabetes, symptom duration).
Competing interests
The author declares that they have no competing interests.
Use of Artificial Intelligence (AI)
The author declares that they did not use generative AI to come up with new ideas for their review.
