Validity and Reliability of the Virtual Reality-Based 9-Hole Peg Test in Stroke Patients

The goal of this observational study is to demonstrate diagnostic value of a VR-based 9-hole peg test (9HPT) for the evaluation of manual dexterity in stroke patients. The main questions it aims to answer are: * Is the VR-based 9HPT a reliable and valid diagnostic tool to evaluate manual dexterity in stroke patients when compared to the physical version of it. * Does the VR-based 9HPT differ between the dominant and non-dominant hand in healthy individuals?

Inclusion Criteria: * Receiving a stroke diagnosis according to the WHO definition * Upper extremity in stage 3 and above according to Brunnstrom motor staging * To be cognitively competent (score of 22 or above on the Mini Mental Test) * Balance of sitting * The patient or his/her relatives have completed the informed voluntary consent form Exclusion Criteria: * Presence of severe aphasia * Presence of cognitive impairment or psychiatric disorders * Detection of a neglect phenomenon * Presence of hemianopsia * Spasticity in the affected arm, 3 or more according to Modified Ashworth Scale
