The United Kingdom Frozen Shoulder Trial is funded by the NIHR Health Technology Assessment programme and is being led by the University of York. 

Adhesive Capsulitis (commonly known as 'Frozen Shoulder') happens when the flexible tissue surrounding the shoulder joint becomes inflamed and thickened resulting in tightening of the tissue.

Most people who experience frozen shoulder eventually get better, even without treatment. When the condition doesn't get better on it's own, patients tend to be referred for hospital treatment. There are a number of interventions available for frozen shoulder, however there is currently limited evidence on the effectiveness of these treatments.

The UK FROST trial aims to evaluate the clinical effectiveness and cost-effectiveness of the treatments for frozen shoulder. In addition, patient experiences of both the surgical interventions and physiotherapy will be examined, providing important patient-centred insight to further guide clinical decision making - this part of the trial is supported by RRIO.
