Pulsed radiofrequency versus phenol injection for post-stroke shoulder pain
Part of Brain & nervous system, Pain clinical trials.
This study compares two treatments to reduce shoulder pain after a stroke: pulsed radiofrequency (using radio waves) and a phenol injection (a chemical that blocks pain). The goal is to see which works better and lasts longer for people with pain and muscle tightness on the affected side.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have had a stroke (either from a blocked or burst blood vessel).
- You have pain in the shoulder on your weak (hemiplegic) side, with a pain score of at least 4 out of 10.
- Your shoulder muscles are stiff, and a doctor has rated the tightness as moderate or more (MAS of 2 or higher).
- You are stable enough to come for follow-up visits for 6 months.
- You have not had radiofrequency or phenol treatment on that shoulder in the last 6 months.
- You do not have a shoulder fracture, dislocation, or a torn rotator cuff that needs surgery.
- You are not pregnant or breastfeeding, and you have no active infections or bleeding problems.

Other trials that look related to this one.
This study tests whether adding phenol to botulinum toxin injections reduces arm spasticity more effectively than botulinum toxin alone in people who have had a stroke at least 6 months ago. The goal is to improve arm movement and ease stiffness.
This study compares two non-invasive treatments—low-level laser therapy and electrical nerve stimulation—to see which works better for relieving moderate to severe shoulder pain in people who have had a stroke. If you have had a stroke in the last 2 weeks to 6 months and have shoulder pain, this trial may be an option for you.
This study tests a treatment for shoulder stiffness and pain caused by muscle tightness after a stroke. It focuses on people who still have some limited shoulder movement and may help improve range of motion and comfort.
This study tests whether heating (radiofrequency) applied to shoulder nerves, with a fluid injection to free up tissue, helps improve pain and movement in people with frozen shoulder (adhesive capsulitis). It compares treating three nerves versus just one nerve to see which works better.
This trial tests if freezing certain nerves in the upper arm (cryoneurolysis) works as well as standard care for reducing shoulder pain and muscle tightness after a stroke or brain injury. It aims to improve function and ease caregiving tasks.
This study tests different lengths of a nerve-blocking treatment called pulsed radiofrequency for shoulder pain. The treatment targets the suprascapular nerve to reduce pain, and the study aims to find the best duration for relief in people with shoulder impingement or rotator cuff tendon problems.
