The first description of frozen shoulder was provided by the French physician E.S. Duplay in 1872. During the 20th century a corresponding Chinese term arose: "50-years shoulder" (wushi jian), referring to the typical age of onset of the disorder; the term frozen shoulder (jianning) is also used in China. While there are numerous references to traditional style Chinese medical treatments for problems of the shoulder area, investigations into the use of the therapies specifically aimed at frozen shoulder have only been described in the last few years.
