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.
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.

Primary outcome measure(s)
Validity and Reliability of the Hypertonia Assessment Tool (HAT) in Adult Post-Stroke Patients — Baseline assessment and repeat assessment within 2-5 days The primary outcome of this study is to evaluate the validity and reliability of the Hypertonia Assessment Tool (HAT) in adult post-stroke patients. Test-retest (intra-rater) reliability will be assessed by repeating the evaluation with the same examiner within 2-5 days, and inter-rater reliability will be examined through assessments conducted by two different examiners on the same day using statistical methods such as the Intraclass Correlation Coefficient (ICC). Validity will be determined by analyzing the relationship between HAT results and established clinical scales, including the Modified Ashworth Scale and Modified Tardieu Scale for spasticity, the Fugl-Meyer Motor Assessment for motor function, the Brunnstrom Staging Scale for recovery stages, and the Burke-Fahn-Marsden Dystonia Rating Scale for dystonia severity.
