We assessed shoulder function in 62 frozen shoulder patients with shoulder function assessment method which devised by Constant for the purpose of evaluating the usefulness of this method. The basis of this method is a 100-point score, composed of individual parameters (pain, ADL, ROM, and power). We found that this method is easy to perform and provides relatively exact overall functional assessment in frozen shoulder patients. So, it will be used for evaluation of treatment results and documentation of disease progression in frozen shoulder. The total score of frozen shoulder patients showed normal distribution and average score was 64.2±15.4. So, we suggest the severity grading of frozen shoulder by total score with this method as follows; 1) total score below 50 point : severe, 2) 51-60 : moderate to severe, 3) 61-70 : moderate, 4) 71-80 : moderate to mild, 5) above 80 point : mild.
