## Brief Summary

This study aims to compare the efficacy of different suprascapular nerve block techniques in patients diagnosed with adhesive capsulitis.

Adhesive capsulitis, commonly known as frozen shoulder, is a condition characterized by pain and restricted range of motion in the shoulder joint, significantly affecting quality of life. The suprascapular nerve provides sensory innervation to the shoulder joint; therefore, nerve blockade is frequently used to alleviate pain. However, there are limited studies evaluating the difference in efficacy between proximal and distal suprascapular nerve blocks.

In this research, two different blockade techniques-at the suprascapular notch and the spinoglenoid notch-will be compared in patients diagnosed with adhesive capsulitis at Istanbul University-Cerrahpaşa between 2024 and 2026. The hypothesis of the study is that the block performed at the spinoglenoid notch provides pain relief comparable to the suprascapular notch block while resulting in less motor blockade.

Patients participating in the study will be randomly assigned to two groups. Both groups will receive an intra-articular corticosteroid injection into the shoulder joint, along with cold application, Codman exercises, and standard medical therapy. Pre- and post-treatment evaluations will include pain severity (NRS), shoulder function (Modified Constant Score), muscle strength, and range of motion.

The results will reveal which technique provides better improvement in shoulder external rotator and abductor muscle strength, shoulder function, and pain relief, thereby offering valuable insights to guide treatment approaches.

## Arms

- **Patients Receiving Suprascapular Nerve Block at the Suprascapular Notch** (ACTIVE_COMPARATOR)
- **Patients Receiving Suprascapular Nerve Block at the Spinoglenoid Notch** (ACTIVE_COMPARATOR)

## Interventions

- **Glenohumeral Joint Injection and Suprascapular Nerve Block** (PROCEDURE) — An intra-articular injection into the glenohumeral joint will be performed using 4 cc of normal saline and 1 cc of betamethasone. Additionally, a suprascapular nerve block will be administered with 5 cc of lidocaine(%2).

## Primary Outcomes

- **Evaluation of the Strength of Shoulder External Rotation and Abduction.** _(time frame: Patients will be assessed at baseline (pre-procedure), 1 week, and 1 month following the glenohumeral joint injection and suprascapular nerve block)_ — Shoulder external rotation strength will be assessed in two different positions: with the arm at the side of the body and with the shoulder in 90 degrees of abduction. Additionally, shoulder abduction strength will be evaluated in two positions: with the shoulder in 90 degrees of abduction and in 90 degrees of abduction combined with 30 degrees of horizontal adduction.
- **Pain Relief** _(time frame: Patients will be evaluated before the glenohumeral joint injection and suprascapular nerve block, as well as 1 hour, 1 week, and 1 month after the procedure.)_ — Pain will be assessed using the Numerical Rating Scale (NRS), which ranges from 0 (no pain) to 10 (worst pain imaginable), at rest, during movement, at night, and overall, both before and after injections into the glenohumeral joint and suprascapular nerve block. Higher scores indicate worse pain outcomes.
- **Passive and Active Range of Motion of Shoulder** _(time frame: Patients will be assessed at baseline (pre-procedure), and at 1 hour, 1 week, and 1 month following the glenohumeral joint injection and suprascapular nerve block.)_ — The shoulder joint's active and passive range of motion will be measured with a goniometer

## Secondary Outcomes

- **The Numeric Rating Scale (NRS)** _(time frame: Assessments were performed before, 1 hour after, 1 week after, and 1 month after the glenohumeral joint injection and suprascapular nerve block.)_
- **Modified Constant Murley Score** _(time frame: Assessments were performed before, 1 week after, and 1 month after the glenohumeral joint injection and suprascapular nerve block.)_
- **Shoulder Disability Questionnaire** _(time frame: Assessments were performed before, 1 week after, and 1 month after the glenohumeral joint injection and suprascapular nerve block.)_
