What this trial studies

This study investigates the effectiveness of high-volume versus low-volume hydrodilatation in patients with adhesive capsulitis, also known as frozen shoulder. Participants will be stratified by the phase of their condition and will receive either 20 ml or 40 ml of hydrodilatation treatment. Outcomes will be measured using the Shoulder Pain and Disability Index (SPADI), Visual Analogue Scale (VAS), and range of motion (ROM) assessments at one, three, and six months post-treatment. The goal is to determine which volume of hydrodilatation yields better results in alleviating symptoms and improving shoulder function.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 30 to 70 with limited shoulder range of motion and pain lasting more than three months.

Not a fit: Patients with conditions that mimic adhesive capsulitis or those who have had recent treatments that may affect their shoulder function may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide clearer guidelines for treating adhesive capsulitis, leading to improved patient outcomes and reduced pain.

How similar studies have performed: Previous studies have shown varying success with hydrodilatation for adhesive capsulitis, but this specific comparison of volume is novel.
