Stroke study: Tizanidine
Official title Effect of Neural Constraints on Movement in Stroke
ClinicalTrials.gov ID: NCT06666673
What this study is testing
What is Tizanidine?
This is an investigational medicine being studied to understand how it affects arm movement after a stroke. It is designed to work by calming signals in the brain that control muscle tightness.
Also referred to as Zanaflex.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study aims to see how a medication called Tizanidine changes arm movement, eye responses, and brain activity.
- Who it's for
- The study is looking for adults who have had a stroke and adults who have not.
- What's involved
- Participants will take Tizanidine and undergo tests to measure arm movement, pupil size, and brain activity.
- Time commitment
- The source text does not specify the total duration or number of visits required.
- Phase 1: an early, usually small safety study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
