The Discriminative Validity of the Korean Motor-Free Visual Perception Test-4

The Motor-Free Visual Perception Test (MVPT) is widely used in rehabilitation settings in Korea, but research on the validity of the MVPT-4, revised in 2015, remains limited. This study aimed to verify the discriminative validity of the Korean MVPT-4 (K-MVPT-4) in healthy individuals and stroke patients. A total of 136 healthy individuals and 81 stroke patients participated were assessed using the K-MVPT-4. Independent t tests and one-way analyses of variance were conducted to examine score differences by the presence of stroke, sex, age, and educational level. Stroke patients scored significantly lower than healthy individuals. Scores also declined with increasing age and lower educational levels, but no significant differences were observed by sex. The findings confirm the discriminative validity of the K-MVPT-4 supporting its clinical applicability as a valid tool for assessing visual perception in stroke patients.
