Brief Summary
Frozen shoulder (adhesive capsulitis) is characterized by pain and a progressive restriction of both active and passive shoulder range of motion, significantly impairing daily activities and quality of life. This study aims to evaluate the effectiveness of USG-guided shoulder injections, when added to a home-based exercise program, in the conservative management of patients with chronic, painful frozen shoulder. In this prospective randomized study, patients diagnosed with painful frozen shoulder will be included. In addition to a standardized home-based exercise program, patients will receive either USG-guided suprascapular nerve block alone or a combination of suprascapular nerve block and subacromial injection. The effects of these approaches on clinical outcomes will be assessed over a 20-week follow-up period. Primary outcome measures include pain intensity assessed by the Visual Analog Scale (VAS), functional status evaluated by the Shoulder Pain and Disability Index (SPADI), and shoulder range of motion. Secondary outcomes include depression level (Beck Depression Inventory), sleep quality, pain phenotype (nociplastic, neuropathic, or nociceptive), hand grip strength, ultrasonographic findings ( (coracohumeral ligament thickness, subacromial bursa thickness) , and patient satisfaction (subjective impression of improvement). The results of this study are expected to provide evidence on the comparative effectiveness and additional benefits of different shoulder injection approaches when combined with home-based exercise therapy in patients with chronic frozen shoulder.

Outcome Measures
Primary Outcomes (3)
VAS pain (0-10) (night and movement)
Visual Analog Scale (VAS) for pain: 0 = no pain, 10 = worst imaginable/unbearable pain.
Baseline, 6 weeks, and 20 weeks
Range of motion (ROM)
Movements of the affected shoulder (flexion, abduction, internal and external rotation) will be measured and recorded using a goniometer. The presence of limitation will be assessed by comparing it to the unaffected side.
Baseline, 6 weeks, and 20 weeks
Shoulder Pain and Disability Index (SPADI)
The Shoulder Pain and Functionality Index (SPADI) is a self-report scale developed to assess the severity of shoulder pain and its impact on functionality. The scale consists of two sub-sections: pain (5 items) and functionality (8 items). Each item is scored from 0 (no pain or difficulty) to 10 (unbearable pain or extreme difficulty). The total score ranges from 0 to 100; higher scores indicate more severe pain and loss of function.
Baseline, 6 weeks, and 20 weeks
Secondary Outcomes (8)
Ultrasonographic evalution (coracohumeral ligament thickness)
Baseline, 6 weeks, and 20 weeks
Sleep quality
Baseline, 6 weeks, and 20 weeks

Study Arms (2)
USG-guided suprascapular nerve block
ACTIVE COMPARATORWith the patient in a seated and comfortable position, a suprascapular nerve block will be administered under ultrasound guidance using a linear ultrasound probe, in accordance with the literature (triamcinolone 20 mg/1 mL + 1% lidocaine 4 mL).
USG-Guided Suprascapular Block Plus Subacromial Injection
ACTIVE COMPARATORWith the patient in a seated and comfortable position, and using a linear ultrasound probe, patients in these group will receive a suprascapular nerve block under ultrasound guidance (triamcinolone 10 mg/0.5 mL + 1% lidocaine 4 mL + 0.5 mL saline), followed by an ultrasound-guided subacromial/deltoid bursa injection (triamcinolone 10 mg/0.5 mL + 1% lidocaine 2.5 mL).
Interventions
USG-guided suprascapular nerve block + home-based exercises
USG-Guided suprascapular nerve block plus subacromial injection + home-based exercises

- Systemic diseases affecting the shoulder, severe degeneration or trauma (e.g., osteoarthritis, rheumatoid arthritis, labral or articular cartilage injuries), or inflammatory rheumatic diseases
- Steroid injection to the affected extremity within the last 3 months, use of oral steroids or NSAIDs, or ongoing surgical/interventional treatment
- Pregnancy or lactation
- Uncontrolled diabetes, heart failure, or uncontrolled systemic diseases (e.g., liver failure, chronic kidney disease, significant endocrine disorders)
- Communication problems or severe psychiatric disorders
