Proximal Humerus Cortical Thickness in Post-Stroke Paresis

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This cross-sectional, retrospective analysis examines whether proximal humerus cortical bone thickness differs between paretic and non-paretic arms in adults with a prior unilateral stroke and hemiparesis. Researchers will compare radiographic measurements from routine shoulder X-rays with systemic DXA bone density values to see if X-ray-based thickness can indicate regional bone loss. Data will come from patients 18 years and older who had a single stroke at least six months ago and have both shoulder radiographs and DXA data available within six months post-stroke. The study aims to determine if standard shoulder imaging could serve as an accessible screening tool for regional osteoporosis risk in the paretic arm.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Patients aged 18 years and older.
* A documented history of a single unilateral stroke that occurred at least 6 months prior to evaluation.
* Presence of clinical hemiparesis.
* Availability of concurrent standard anteroposterior (AP) shoulder radiographs taken within 6 months post-stroke alongside systemic DXA measurements.

Exclusion Criteria:

* History of surgical intervention in either shoulder. History of a proximal humerus fracture.
* Co-existing metabolic bone diseases, such as primary hyperparathyroidism or osteomalacia.
* History of malignancy.
* Documented history of corticosteroid use.
* Imaging artifacts that compromise the accuracy of DXA measurements.
* History of a secondary stroke.
