Frozen shoulder syndrome affects as many as a million Canadians a year, mainly people over 40, with a higher incidence in women. There have been many theories about what causes FSS, but no definitive answer.
Frozen Shoulder Syndrome (FSS) is the restriction of movement from injury, lack of use and pain. Rheumatic disease progression and recent shoulder surgery is a cause of FFS and rarely appears in people under the age of 40. While the shoulder is the most movable joint in the body, it is an unstable joint due to its great range of motion allowed. Instability can increase the likelihood of joint injury.
