NCT ID NCT07429383

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

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.

Who can take part

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.

Ages

Inclusion Criteria: * Age 18 years and older * Clinically and radiologically confirmed diagnosis of stroke (ischemic or -hemorrhagic) * Brunnstrom stage between 2 and 6 * Presence of post-stroke hypertonia (spasticity, dystonia, or rigidity) * Cognitive level sufficient to cooperate with assessments (Mini-Mental State Examination (MMSE) score \>23 or equivalent clinical evaluation) * Provision of written informed consent Exclusion Criteria: * Age under 18 years * Presence of severe accompanying neurodegenerative diseases (e.g., Parkinson's disease, multiple sclerosis, amyotrophic lateral sclerosis) * Presence of primary musculoskeletal disorders affecting motor performance (e.g., rheumatologic diseases, fractures) * Brunnstrom stage of 1 * Severe aphasia, impaired consciousness, or cognitive deficits preventing effective communication and cooperation * Any psychiatric disorder that may interfere with study participation
