Brief Summary

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.

Outcome Measures

Primary Outcomes (9)

  • 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.

    at the recruited time

  • Change from the baseline of nerve cross-sectional area after the injection

    at one month later after the injection

  • Dynamic shoulder motion under ultrasound imaging

    Subacromial motion metrics, based on the reciprocol movement of the greater tubercle of the humerus in relation to the acromion

    Baseline and after intervention (if available)

  • 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.

    at one month later after the injection

  • Visual analogue scale at the recruited time

    The pain scale to evaluate pain, from 0 to 10. The lower means less pain.

  • Change from the baseline of Visual analogue scale after the injection

    The pain scale to evaluate pain, from 0 to 10. The lower means less pain.

    at one month later after the injection

  • 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.
