Cold therapy for muscle tightness: long-term effects and brain changes
Part of Brain & nervous system, Pain clinical trials.
This study tests if freezing a nerve (cryoneurolysis) can reduce muscle tightness (spasticity) and improve arm movement. It also looks at how the brain may change after treatment. If you have tight muscles that improved with a numbing nerve block, you may be eligible.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have had a diagnostic nerve block that reduced your muscle tightness and did not cause unwanted loss of function.
- Your muscle tightness should score 2 or higher on the Modified Ashworth scale (a measure of stiffness).
- You must be able to flick or move your arm or hand at least a little.
- You have not had Botox injections for spasticity in the last 3 months.
- If you take oral medications for spasticity, you must be willing to keep the same dose during the study.
- You can understand and follow instructions in English.

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 tests if freezing specific nerves (cryoneurolysis) can reduce pain caused by muscle tightness (spasticity) after a brain or spinal cord injury, or from multiple sclerosis. It is for people who already get Botox injections for this pain.
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 whether a gentle, non-invasive brain stimulation (tDCS) can help reduce muscle stiffness and improve arm or leg movement in people who had a stroke. If you have tight or stiff muscles after your stroke, this might be a good option to explore.
This study looks at whether a temporary numbing injection (nerve block) can predict how well a longer-lasting freezing treatment (cryoneurolysis) will relieve chronic pain or muscle tightness. If you're eligible, you'll get the freezing treatment, which may provide longer-term relief.
This study tests a cold treatment called cryoneurolysis to reduce painful muscle tightness in the shoulder or elbow for people with cerebral palsy. It is for those who have tried other treatments like injections or medications and found they didn't work well or weren't an option.
