The Effect of Combined Hydrodilatation, Corticosteroid Injection, and Joint Mobilization for Treament of Frozen Shoulder

"Patients in the Comb group will receive hydrodilatation of the affected shoulder and subdeltoid bursa injection for 2 times in 2-week interval. Patients also receive mobilization exercise and conventional physical therapy (including physical modalities and stretch exercise), 3 times a week, for 8 weeks.~The injectates for hydrodilation include 10mg triamcinolone, 2cc 1% xylocaine, and 17cc normal saline for both posterior and anterior shoulder joint injection. 10mg triamcinolone and 2cc 1% xylocaine will also be injected into the subdeltoid bursa of the affected shoulder. All injections will be performed under ultrasound guidance. For shoulder joint injection, ａ21 gauge, 3-inch needle will be used; and a 22 gauge, 1.5 inch needle will be applied for subdeltoid bursa injection."

The physiotherapy program includes physical modalities (heat therapy and electric therapy) and therapeutic exercise (stretching, ROM exercise, and strengthening), three times a week, and will be continued for 8 weeks or until total recovery of the symptoms. The stretching exercise program is similar to the stretching exercise described above. For mimicking injection in the Comb group, patients in the PT group will receive 2cc 1% xylocain injection at the posterior deltoid muscle.
