Characteristics of Visual-Perceptual Function Measured by the Motor-Free Visual Perception Test-3 in Korean Adults

Abstract

ObjectiveTo 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.MethodsThe 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.ResultsTotal 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.ConclusionVisual 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.

Relationship between Visual Perception and Microstructural Change of the Superior Longitudinal Fasciculus in Patients with Brain Injury in the Right Hemisphere: A Preliminary Diffusion Tensor Tractography Study

“…Visual perceptual deficits are primarily the result of right cerebral hemisphere damage that occurs following a stroke [ 1 ]. These deficits have been explained as a deterioration in the process of unconscious inference from the information contained in the visual images produced by interactions from the frontal to the parietal lobe [ 2 , 3 ]. Impairments of visual perception are present in approximately 35 to 75% of patients with brain damage, and often lead to severe restrictions of independent functioning [ 3 ].…”

Therapeutic Potential of 3D Printing Pen in Stroke Rehabilitation: Case Reports

“…In particular, the time required for MVPT-3 significantly decreased after the training program. The MVPT-3 is easily conducted within 20-30 minutes in people aged 4-95 years [5,10]. This patient performed the MVPT-3 in 52 minutes before the 3D printing pen training program, 4/6 https://doi.org/10.12786/bn.2017.10.e8…”

“…He did not receive any occupational therapy for 4 weeks of the 3D printing pen training program. Each visualperceptual and hand function were assessed with the Motor-Free Visual Perception-3 (MVPT-3) [5] and the box and block test (BBT) [6] before and after the program, respectively. In the BBT, the number of blocks per minute increased from 37 to 39 after the training program.…”

“…Dividing our patients into groups according to their age-related norms [34,35]: age 50-59 years (n = 3):36/60 correct responses, norms: 52.11 ± 5.87; age 60-69 years (n = 3) was 26/60 correct responses, norms: 47.61 ± 6.33; age 70-79 years (n = 2): 21.5/60 correct responses, norms 42.87 ± 7.…”
