What this trial studies

This clinical trial aims to investigate the effectiveness of hyaluronidase injections in reducing shoulder pain associated with post-stroke myofascial dysfunction. It will utilize T1rho MRI and ultrasound shear strain mapping to quantify changes in muscle function and pain levels before and after treatment. The study will compare the outcomes of patients receiving hyaluronidase versus a placebo, focusing on pain reduction, range of motion, and overall quality of life. The trial seeks to clarify the role of hyaluronic acid accumulation in shoulder pain post-stroke.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have experienced hemiparesis from a stroke and exhibit specific shoulder mobility issues.

Not a fit: Patients with other neurological conditions or significant cognitive dysfunction may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly alleviate shoulder pain and improve recovery outcomes for stroke patients.

How similar studies have performed: While the approach of using hyaluronidase for myofascial dysfunction is novel, similar studies have shown promise in treating pain through targeted interventions.
