简要总结
This is a pilot study examining the feasibility and efficacy of using Apple iPad applications ("apps") during therapy interventions that target visual motor, visual attention, and visual-spatial reasoning skills in school age children who were previously treated surgically for hydrocephalus. Each subject will participate in an initial assessment and baseline MRI, followed by 6-weeks of iPad app-based interventions, and finally a follow-up assessment and a follow-up MRI.
详细描述
Long term visuospatial and visuomotor functional deficits are common in pediatric patients with surgically treated hydrocephalus. The deficits are often mild/moderate at early school age although the gap may widen as the children grow older, leading to increasing adverse impact on school performance and academic achievement. The proposed study will generate initial pilot data for the usage of iPad application based therapy intervention for the treatment of cognitive deficits common to pediatric hydrocephalus. It will help determine the optimal intensity and duration of training protocol adapted for the study. In addition, the sensitivity of neuroimaging (DTI) in response to the therapy will be assessed and validated as a biomarker that reflects the neuroanatomical alterations underpinning the outcome changes. This study will generate the crucial data to support the design of future Phase III clinical trial with the long term goal as changing the current standard of care in order to prevent neurocognitive and sensorimotor deficits before the injury to neural circuitry becomes irreversible.
The participants who meet the inclusion criteria and do not opt-out of participation will be called by a study coordinator to ensure eligibility and to schedule the initial assessment date. Participation in this study will include 8-10 study visits. These visits include 2 neuropsychological assessments, 2 MRI visits, and 6 weekly visits during intervention phase. MRI visit can be combined with the neuropsychological assessment visit if possible at both the pre- and post intervention time points.

结局指标
主要结局
Visual-spatial processing
时间窗: Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment)
The Arrows subtest of the revision of A Developmental Neuropsychological Assessment (NEPSY-II), designed to assess the ability to judge line orientation. The Arrows subtest-level scores range from 1-19, with a low score indicating poor visuospatial skills, while a high score indicates excellent visuospatial skills.
Basic visual perception, visual-motor integration, and graphomotor skills
时间窗: Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment)
The Beery-Buktenica Developmental Test of Visual Motor Integration 6th Edition (Beery VMI). The composite score is the sum of the scores of three subtests: Visual-Motor Integration, Visual Perception, and Motor Coordination. The scores for the subtests are calculated using pre-formatted tables to determine the standard score, scaled score, and percentile based off of the raw score. The composite score has a mean of 100 and a standard deviation of 15 for all ages groups, and are based on the means of raw score distribution. The higher the score, the higher the percentile, the greater the subject's ability for visual perception, visual motor-integration, and graphomotor skills.
Visual-spatial processing and mental rotation
时间窗: Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment)
The Geometric Figures subtest of the revision of A Developmental Neuropsychological Assessment (NEPSY-II), designed to assess mental rotation, visuospatial analysis, and attention to detail. The Geometric Figures subtest-level scores range from 1-19, with a low score indicating difficulty with visuospatial perception, including mental rotation and with a high score indicating excellent visuospatial perception.
Selective visual attention
时间窗: Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment)
The Cancellation subtest of the revision of the Wechsler Intelligence Scale for Children (WISC-IV), designed to measure processing speed. The Raw Score is converted to a Scaled Score (1-19), which is converted to a Percentile Rank. The higher the raw score, the higher the Scaled Score, and the Percentile Rank. The higher the score, the better the visual processing speed.
Visual-spatial decision making and visual-motor speed
时间窗: Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment)
Coding subtest of the revision of the Wechsler Intelligence Scale for Children (WISC-IV), designed to measure visual-motor speed and complexity and motor coordination. The Raw Score is converted to a Scaled Score (1-19), which is converted to a Percentile Rank. The higher the raw score, the higher the Scaled Score, and the Percentile Rank. The higher the score, the better the visual-spatial and visual-motor skills.
General intellectual functioning, including visual-spatial reasoning
时间窗: Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment)
The Perceptual Reasoning Index (PRI) of the revision of the Wechsler Abbreviated Scale of Intelligence (WASI-II). PRI includes the subtests Block Design and Matrix Reasoning. The Raw scores of the subtests are converted to T-scores, which are summed for a Sum of T-scores for Perceptual Reasoning. The Sum of T-scores for Perceptual Reasoning is converted to a Composite Score of the PRI, which can be used to find the Percentile Rank. The Block Design raw scores range from 0-51 and the Matrix Reasoning raw scores range from 0-23. The T-score ranges are from 20-54. The Composite Scores range from 40-160.The higher the scores of the subtests, the higher the score on the PRI, the greater the subject's ability to analyze and synthesize abstract visual stimuli and the subject's fluid intelligence, broad visual intelligence, classification and spatial ability, knowledge of part-whole relationships, simultaneous processing, and perceptual organization.
Fine motor dexterity
时间窗: Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment)
The Purdue Pegboard test, designed to measure manual dexterity and bimanual coordination.The test is comprised of 5 scores, each of the subtests are timed. Scores are continuous, the higher the score the greater the subjet's manual dexterity and bimanual coordination.
