New tool could help doctors spot muscle problems after stroke
NCT ID NCT07429383
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study checks if a tool called the Hypertonia Assessment Tool (HAT) can correctly identify different types of muscle tightness in adults who have had a stroke. The tool was already tested in children with cerebral palsy, but not in adults after stroke. Researchers will test 60 stroke survivors to see if the tool gives consistent results and matches other standard tests.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could give doctors a reliable way to identify different types of muscle tightness after stroke, leading to better rehabilitation plans.
- What could go wrong
- This is a small, early-stage validation study with only 60 participants. The tool may not work as well in adults as it does in children, or results may not apply to all stroke survivors.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Adult patients aged 18-80 years who have been clinically and radiologically diagnosed with ischemic or hemorrhagic stroke and who developed upper extremity hypertonia will be recruited from the Physical Medicine and Rehabilitation Clinic of SBU Fatih Sultan Mehmet Training and Research Hospital. Participants will be in Brunnstrom stages 2-6 and clinically stable at the time of assessment. The study population consists of individuals in the chronic or subacute post-stroke phase undergoing routine rehabilitation follow-up.
