The suprascapular nerve is the first nerve that branches from the upper trunk of brachial plexus. It receives signals transmitted from the fifth and sixth cervical root. The clinical importance of suprascapular nerve is mainly based on its distribution of 70% sensory innervation to the glenohumeral joint. After being divided from the upper trunk, the suprascapular nerve goes laterally and posteriorly. First, it passes underneath the omohyoid muscle, and then goes through the suprascapular notch into the suprascapular fossa. If there are some problems inside the supraspinatus muscle at the suprascapular fossa, the suprascapular nerve below it may be compromised. After the suprascapular nerve passes the suprascapular fossa, it courses through the spinoglenoid notch, and then goes into the infraspinatus fossa to innervate the infraspinatus muscle. Based on the sensory and motor innervation of the suprascapular nerve to the shoulder joint, the sonographic images of the suprascapular nerves would add tremendous values in assessing patients with refractory shoulder pain. Although there are some studies trying to measure the size of the suprascapular nerve, no available research can be found in stroke patients. Our study aims to explore the ultrasound morphology of the suprascapular nerves as well as subacromial dynamic imaging in patients with stroke. A control group without stroke will be recruited for comparison.

Nerve cross-sectional area at the recruited time
The measurements of the nerve cross-sectional area were conducted by another specialist with the image processing software (Image J). For the most proximal section of the suprascapular nerve, the cross-section of the nerve fascicles inside the hyperechoic epineurium were measured. In the segment over the supraspinatus and infraspinatus fossae, the whole nerve's cross-section including its epineurium were measured.

The Chinese version of the Shoulder Pain and Disability Index at the recruited time
The Chinese version of the Shoulder Pain and Disability Index (SPADI) tool. The SPADI tool consisted of 13 questions categorized in two domains: pain and disability. They were instructed to indicate the level of influence on a 10 cm visual analogue scale for each question with a rating from 0 (no pain or no difficulty) to 10 (worst pain or extreme difficulty). The scores from the pain and functional domains were averaged to generate the total score of SPADI, with a highest value of 100 points.
Subdeltoid bursa injection, suprascapular nerve block, or posterior glenohumeral joint injection. The participants should only receive one type of the injection mentioned above.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
Adult and stroke patients (≥ 20 year old). All the participants were those visiting the department of physical medicine and rehabilitation for musculoskeletal complaints.

Visual analogue scale at the recruited time
The pain scale to evaluate pain, from 0 to 10. The lower means less pain.

Range of the motion and impingement at the recruited time
Range of the motion of the shoulder, from 0 degree to 180 degree. The lower means more limitation. The impingement of supraspinatus tendon, subdeltoid bursa and acromion are evaluated under ultrasonography. The transducer is positioned along the scapular plane lateral to the acromion. The participant gradually raises the arm, and the examiner simultaneously observes whether there is bulging of the subacromial bursa and abnormal elevation/movement of the humeral head.
