The purpose of this study was to evaluate the effectiveness of hydraulic managment in patients with frozen shoulder which were not improved with previous conservative treatment.

The study population was consited of 4 men and 6 women, 6 cases were affected in the dominant side and 4 cases in the non-dominat side and the duration of frozen soulder was ranged from 3 to 18 months, with mean duration of 8.8 months.

Associated conditions were trauma or fractures in 5 cases and cervical radiculopathy in 2 cases.

The results were as follows:

1) The pre-treatment shoulder ROM was 77^o of flexion, 53^o of abduction, 21^o of external rotation, and 39^o of internal rotation, and more severely limited in external rotation, abduction than in flexion, internal rotation.

2) The post-treatment ROM was 132^o of flextion, 118^o of abduction, 64^o of external rotation, and 68 of internal rotation.

3) With the hydraulic management, ROM were increased 55^o of flexion, 65 of abduction, 43^o of external rotation and 29^o of internal rotation.

4) The performance of ADL's and subjective symptoms such as pain, stkffness, sleep disturbance showed moderate to marked improvement in 8 cases.

5) No complications were observed with the hydraulic management.

With the above results, hydraulic distension was thought to be the effective method for improvement of subjective symptoms and increment of ROM in patients with frozen shoulder.
