The authors measured the grip strength and pinch strength and range of motion of the shoulder per 2 weeks in 44 patients of frozen shoulder who were treated at the Department of Rehabilitation Medicine, St. Mary's Hospital during 1 year of period from March 1084 to August 1985.

The results were as follows;

1) Among the 44 cases, female were 15 cases and males were 29 cases and the highest age incidence was fifty to sixth decades.

2) Average duration of symptom at admission was 3.69±2.70 months.

3) The left hand was involved in 17 cases and right hand in 20 cases and both hands in 7 cases

4) The etiology of the frozon shoulders in 26 cases of 44 cases was idiopathic(primary) and 12 cases were associated with direct trauma and 2 cases with mastectomy complication and 3 cases with absolute bed rest due to other site's lesion and 1 case with silicosis.

5) shoulder range of motion at admission was 110.79±25.70⁗in flexion, 84.54±22.77⁗in abduction, 34.36±23.5⁗in internal rotation, 35.12±25.4⁗ in external rotation. The range of motion of the shoulder measured per 2 weeks increased continuously until 8 weeks.

6) At admission, average grip strength was 9.50±7.08 kg and average pinch strength was 4.91±2.93 kg. Both grip strength and pinch strength increased statistically significantly until 4 weeks and did not increased after 4 weeks.
