Frozen shoulder is characterised by stiffness and restriction of movement leading to a high degree of shoulder joint immobilisation (passive and active movements).
In most cases there is also some localised pain that can also cause secondary pain in the neck and trapezius muscle.
Patients are generally unable to raise their arm above 45 degrees and often any movement that involves external shoulder rotation inhibits pain.
Pain at night is often more severe, and a secondary side effect of frozen shoulder is insomnia.
It is most common over the age of 40 and more prevalent in woman.
