To adapt and standardize the Motor-Free Visual Perception Test-3 (MVPT-3) to Koreans and investigate the change in visual-perceptual function using the MVPT-3 in healthy Korean adults.
The Korean version of the MVPT-3 was developed through a cross-cultural adaptation process according to 6 steps, including translation, reconciliation, back translation, cognitive debriefing, feedback, and final reconciliation. A total of 321 healthy Korean volunteers (mean age, 51.05 years) were recruited. We collected participant demographic data, such as sex, age, and years of education, and performed the Korean version of the Mini-Mental State Examination (K-MMSE) and MVPT-3. Internal consistency of the MVPT-3 and the relationships between demographic data, K-MMSE and MVPT-3 scores were analyzed. The results of this study were compared with published data from western countries including the United States and Canada.
Total score on the MVPT-3 was positively correlated with years of education (r=0.715, p<0.001) and K-MMSE score (r=0.718, p<0.001). However, it had a negative correlation with age (r=-0.669, p<0.001). A post-hoc analysis of MVPT-3 scores classified age into 5 groups of ≤49, 50-59, 60-69, 70-79, ≥80 years and years of education into 4 groups of 0, 1-9, 10-12, ≥13 years. No significant differences in MVPT-3 scores were observed according to sex or country.
Visual perception was significantly influenced by age, years of education, and cognitive function. Reference values for the MVPT-3 provided in this study will be useful for evaluating and planning a rehabilitation program of visual perceptual function in patients with brain disorders.

Objective: The purpose of this study was to determine the ability of Mini Mental Status Examination (MMSE) and Motor Free Visual Perception Test (MVPT) to predict driving outcome in subject with brain damage.
Method: Fifteen brain damaged subjects were administered for this study. Fourteen subjects had brain damage due to stroke and only one subject had traumatic brain injury. All subjects were evaluated with MMSE and MVPT. We used total score for each tests. Subjects were also evaluated in driving simulator that measured their operational responses to filmed driving situation. Correlation between neuropsy-chological tests score and driving simulator score were analyzed.
Results: 1) By average score, MMSE score was 26.6 and MVPT score was 23.7. Driving simulator score was average 30.1. 2) There was good correlation between MVPT score and driving simulator score (r=0.675, p＜0.01). 3) There were no correlation between MMSE and driving simulator score nor between MMSE and MVPT score.
Conclusion: MVPT can be used as screening test for identifying person who are not ready to drive after getting brain damage. (J Korean Acad Rehab Med 2002; 26: 268-272)
Objective: To investigate the correlation of main risk factors and cognitive-perceptual functions of stroke patients assessed with Mini-mental status examination (MMSE) and Motor-free visual perception test (MVPT) scores.
Method: Subjects were 41 stroke patients from 35 to 70 years of age. Data collection was done through chart review on risk factors of stroke including hypertension, diabetes mellitus, heart disease, hypercholesterolemia, and cigarette smoking. Three months after the onset of stroke, MMSE and MVPT were performed.
Results: The subjects with diabetes had significantly lower scores in MMSE (p＜0.05) and MVPT (p＜0.05) compared to those with nondiabetics. The subjects with left hemispheric lesion scored higher in MMSE than those with right hemispheric lesion (p＜0.05).
Conclusion: Among the several risk factors, diabetes mellitus has significant relationship to cognitive and visual perceptual function in the stroke patients.
