About

Adhesive capsulitis is a disease that negatively affects a person's quality of life by causing severe pain and limitation in the movements of the shoulder joint in all directions. Conservative approaches including nonsteroidal anti-inflammatory drugs or oral corticosteroid usage and physiotherapy program are the first choice for the treatment. However, painful exercises usually prevent patients from fully participating in the physiotherapy program. For this reason, interventional procedures such as intra-articular corticosteroid injection (IAI) and suprascapular nerve block (SSNB) are preferred to be applied before the physiotherapy program.

The aim of this study is to reveal both short and long-term effects of SSNB and IAI combination on pain, shoulder range of motion (ROM), disability, and quality of life in patients with adhesive capsulitis. It is hypothesized that the addition of SSNB to IAI results in greater improvements in pain, passive and active shoulder ROMs, disability, and quality of life.

Full description

Adhesive capsulitis (AK), also known as frozen shoulder, is a disease that negatively affects a person's quality of life by causing severe pain and limitation in the movements of the shoulder joint in all directions. Although the underlying etiology is not clear, it may develop as a result of primary (idiopathic) or secondary causes such as diabetes mellitus, malignancy, thyroid dysfunction, hypoadrenalism, Parkinson's disease, stroke, cardiac and pulmonary diseases, or local shoulder problems such as trauma, tendinitis, rupture. Prolonged immobilization after injuries is another important risk factor for adhesive capsulitis. It is more common in women between the ages of 40-60. Conservative approaches including nonsteroidal anti-inflammatory drugs or oral corticosteroid usage and physiotherapy program are the first choice for the treatment. The physiotherapy program consisting range of motion (ROM), stretching and strengthening exercises are often painful and prevent the patient's full participation. For this reason, interventional procedures such as intra-articular corticosteroid injection (IAI) and suprascapular nerve block (SSNB) are preferred to be applied before the physiotherapy program.

The aim of this study is to reveal both short and long-term effects of SSNB and IAI combination on pain, shoulder ROM, disability, and quality of life in patients with adhesive capsulitis. It is hypothesized that the addition of SSNB to IAI results in greater improvements in pain, passive and active shoulder ROMs, disability, and quality of life. The primary outcome measure of the study is determined to be the Shoulder Pain and Disability Index (SPADI), while the secondary outcome measures to be the Numeric Rating Scale (NRS), active and passive ROMs, and the Short Form 36 (SF-36).
