Can healthy volunteers participate?
No
Key exclusion criteria
Cognitive deficit that preclude patients
from reliably using subjective outcome measures scales - Mini-Mental State Examination (MMSE) < 23.

Language deficits (inability to follow 2-
stage command) or limited English language that preclude patients from reliably using subjective outcome measures scales

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following consent and baseline measures particpants will be randomized to receive suprascapular nerve block or placebo injection. Allocation will be managed by a pharmacist external to the project.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation - computer generated by a software program
Masking / blinding
Blinded (masking used)

Summary
Brief summary
Shoulder pain is a common and debilitating symptom for a large number of people following a stroke. The cause of shoulder pain is usually related to several factors, including trauma, inflammation and positioning. In cases when shoulder pain is unable to be prevented, current treatment options include arm supports, physiotherapy techniques, and simple analgesic medication.

It is commonly observed that shoulder pain persists or is inadequately controlled by these interventions. This research aims to study the effect of an injection that numbs the nerve (Suprascapular Nerve) that supplies pain fibres to the shoulder. The technique has previously been proven safe and effective in the treatment of shoulder pain associated with rheumatoid arthritis and degenerative shoulder conditions.
