Shoulder Hand Syndrome, Complex Regional Pain Syndromes
Tolerability of Suprascapular and Median Nerve Blocks for the Treatment of Shoulder-hand Syndrome
Shoulder-hand syndrome (SHS) in stroke patients is painful and lowers quality of life. Unfortunately, the cause of SHS is not known, diagnosing SHS can be difficult, and treating it can be hard.
- Trial name
- NCT03291197
- Testing
- Suprascapular and median nerve blocks
- Where
- Canada
- Volunteers

Upper Limb Nerve Block
The Study of Regional Hemodynamic Changes After Specific Brachial Plexus Block by Ultrasound Guidance
Phase 1 Sympathetic block leads to vasodilatation and increases in blood flow. However, regional hemodynamic changes of radial and ulnar artery after specific nerve block of brachial plexus remains unclear.

- NCT02139982
- Testing
- specific nerve block, ropivacaine
- Where
- China
