AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults who have had a stroke and now have muscle stiffness (hypertonia). It tests a tool that sorts the type of stiffness.

Age: 18 to 80 years
Sex: Women and men can join.
Disease stage: Confirmed stroke (ischemic or hemorrhagic), Brunnstrom stage between 2 and 6, with muscle stiffness after the stroke (spasticity, dystonia or rigidity).

Main reasons for not taking part

Severe other nerve diseases, such as Parkinson's disease, multiple sclerosis or ALS
Bone, joint or muscle disorders that affect movement, such as rheumatologic diseases or fractures
Brunnstrom stage of 1
Severe aphasia, impaired consciousness or thinking problems that prevent cooperation
A psychiatric disorder that may interfere with taking part

About the trial

What the trial wants to find out

In this study, the validity and reliability of the Hypertonia Assessment Tool (HAT), which has previously been validated in the pediatric cerebral palsy (CP) population, will be evaluated in adult individuals who have experienced a stroke. The HAT is a specific clinical instrument designed to differentiate subtypes of hypertonia, including spasticity, dystonia, and rigidity.

Read full original descriptionShow less

Accurate classification of hypertonia subtypes following stroke is crucial for guiding rehabilitation strategies. However, the HAT has not yet been validated in the adult post-stroke population. This study will be conducted at the Physical Medicine and Rehabilitation Clinic of SBU Fatih Sultan Mehmet Training and Research Hospital. The study aims to evaluate the validity and reliability of the HAT for use in adults with stroke.
