We investigated the shoulder function of the frozen shoulder after an average of thirty months (12 to 108 months) of the conservative treatment. In this study, 17 shoulders of 16 patients (13 males and 3 females) of non-traumatic frozen shoulder without rotator cuff tear were investigated. The mean age of all cases was 66 years old, ranging from 47 to 76 years old. At an average of 30 months follow-up, the clinical results and shoulder function including subjective and objective evaluation, range of motion and shoulder strength using micro FET, were investigated. The mean JOA score was 63.7 points at the initial treatment and 82.5 points at the end of the treatment. After thirty months of the treatment, JOA score was improved to 93.4 points. About 88% of the patients were satisfied with their daily living, although 16.7% of the patients changed sports activity level or their work. Seven of 17 patients who were satisfied with their ADL, restricted some concrete action related to shoulder function such as scratching their back. The range of motion of flexion, abduction and external rotation of the affected side tended to be lower compared with the normal side, but not significantly. The strength of the shoulder of the affected side was improved without a significant difference from normal side. The prognosis of the frozen shoulder was relatively good with a little discomfort for living and a limitation of sports activity.
