Frozen shoulder is a painful and debilitating condition causing stiffness and disability in the affected shoulder and arm. It happens when the flexible tissue surrounding the shoulder joint (capsule) becomes inflamed and thickened, resulting in contraction (tightening) of the tissue and scarring. The shoulder becomes very tight, painful and stiff. It affects around 1 in 12 men and 1 in 10 women of working age, interfering with their work, home and leisure activities.
The aim of this study is to compare these three treatments for both clinical and cost effectiveness.
