Abstract
Background: Adhesive capsulitis causes pain and limited mobility. Hydrodilatation is an effective, minimally invasive treatment, but the optimal volume is unclear. This study compares the pain and function improvement from large-volume (40 mL) versus small-volume (10 mL) ultrasound-guided hydrodilatation in patients with adhesive capsulitis.
Methods: This study was conducted at Phramongkutklao Hospital in Bangkok, Thailand, with Thai adults aged 20 and older who had adhesive capsulitis. Participants had a pain score of 4 or higher on the Visual Analogue Scale (VAS) and limited movement in at least two directions. They were divided into two groups. One group received ultrasound-guided hydrodilatation with either 10 mL or 40 mL of a solution containing steroids, xylocaine, and saline. Researchers assessed pain (VAS) and shoulder function (Thai Shoulder Pain and Disability Index) at the start and one month later, and they recorded any side effects.
Results: Twenty-four participants were randomized into two groups of twelve. Both groups showed significant improvements in Visual Analogue Scale (VAS) and Thai Shoulder Pain and Disability Index (SPADI) scores after one month (p
Conclusion: Ultrasound-guided hydrodilatation with 10 mL or 40 mL effectively reduces pain and improves function in adhesive capsulitis, with no significant differences between the two volumes.
