A computerized Visual Perception rehabilitation programme with interactive computer interface using motion tracking technology — a randomized controlled, single-blinded, pilot clinical trial study:
Clinical Rehabilitation, 2009Co-Authors: Si Hyun Kang, Sang Yoon Sung, Kwang Nam Choi, Heon Jong ParkAbstract:Objective: To assess the effectiveness of a computerized Visual Perception rehabilitation programme using motion tracking technology for Visual Perception impairment.Design: Randomized controlled, single-blinded, pilot clinical trial study.Setting: Inpatient rehabilitation hospital.Subjects: Sixteen left hemiplegic patients with Visual Perceptional impairment.Intervention: Subjects were randomly assigned to receive either (1) participation in a computerized Visual Perception rehabilitation programme with an interactive patient—computer interface applying motion tracking technology based on the CAMSHIFT algorithm or (2) use of the PSS CogRehab program for three sessions per week, 30 minutes per session for four weeks.

MAIN MEASURES: Mini-Mental Status Examination, Motor-free Visual Perception Test and Modified Barthel Index were assessed at the beginning and end of the training. A survey was conducted to evaluate the degree of patients' interest using an interest scale. RESULTS: After training, the mean (SD) Motor-free Visual Perception Test score increased significantly in both experimental group (from 65.8 (19.5) to 77.8 (28.7)) and control group (from 68.3 (11.4) to 74.1 (14.8)) (P

Modifying and evaluating efficacy of interactive computerized program using motion tracking technology to improve unilateral neglect in patients with chronic stroke.
Medicine, 2018Co-Authors: Si Hyun Kang, Kwang Nam ChoiAbstract:Background To modify and evaluate the efficacy of a computerized Visual Perception rehabilitation program using interactive motion tracking technology with unilateral neglect after chronic stroke. Methods Study design is single-blinded (analyst-blinded) controlled prospective clinical trial. Subjects are 16 patients with chronic stroke and unilateral neglect for over 6 months and 19 healthy volunteers. We modified our previous program to 9 tasks with built-in scoring system, and the subjects performed 3 sessions per week, 30 minutes per session for 4 weeks. Results Scores for the Modified Barthel Index (MBI), Mini-Mental State Examination (MMSE), Motor-free Visual Perception Test (MVPT), Line bisection Test, Star cancellation Test, Forward Digit Test, and Backward Digit Test showed significant improvement at the end of the sessions in the patient group. By comparing the parameters of built-in scoring system of each task among the control group, the first session of training in the patient group, and the last session of training in the patient group, we categorized the parameters for optional measurement to determine the effect of training or to be a candidate for evaluative use. Conclusions Our modified computerized Visual Perception rehabilitation program using improved unilateral neglect in patients post-stroke. Built-in scoring system in this program was helpful to assess availability of it more objectively.

The discriminative validity of three Visual Perception Tests
New Zealand journal of occupational therapy, 2011Co-Authors: Ted Brown, Emma Sutton, Stefan Wigg, Sharon Glass, Stephen Elliott, Ralda Bourne, Deidre D Morgan, Aislinn LalorAbstract:This study assessed the discriminative validity of three Visual perceptual Tests: the Developmental Test of Visual Perceptual Skills-Adolescent and Adult (DTVP-A), the Motor-Free Visual Perception Test-Third Edition (MVPT-3), and the Test of Visual Perceptual Skills-Third Edition (TVPS-3). The DTVP-A, MVPT-3, and TVPS-3 were all originally developed and standardised within the United States. A total of 49 participants diagnosed with a neurological impairment and 172 healthy participants living in Australia completed the three Tests. Statistically significant results provide evidence in support of the three Tests' abilities to successfully discriminate between the two groups of participants with a known diagnostic difference. This provides evidence to support the three Tests use in clinical and professional settings, to Test for Visual perceptual dysfunction.

An Examination of the Construct Validity of the Motor-Free Visual Perceptual Test—Third Edition (MVPT-3) Using Rasch Analysis with Adult Participants:
Otjr-occupation Participation and Health, 2010Co-Authors: Ted BrownAbstract:Visual perceptual skills of adults are often assessed by occupational therapists using standardized Tests. The Motor-Free Visual Perception Test—Third Edition (MVPT-3) is a frequently used Test, although its construct validity has not been thoroughly evaluated. The purpose of the study was to consider the construct validity of the MVPT-3 by evaluating its scalability/interval level measurement, unidimensionality, lack of differential item functioning (DIF), and hierarchical ordering of its items when completed by a group of adult participants. The Visual perceptual performance scores from a sample of 221 participants 20 years or older (49 adults with neurological impairment and 172 adults without) were used to complete a Rasch analysis (RA) of the MVPT-3. When analyzed using RA, the MVPT-3 exhibited adequate measurement properties. However, several MVPT-3 scales exhibited RA misfit (items 40, 45, 54, 56, 61, 64) or DIF (items 57, 60, 61). The construct validity, scalability, unidimensionality, hierarchica...
