Sponsor's own description
The goal of this semi-experimental study is to investigate whether bilateral (limbs of both sides of the body, such as left and right hands) perceptual-motor (PM) exercises and unilateral (limb of only one side of the body, such as only the left hand) PM exercises affect manual dexterity and visuospatial memory in children with nonverbal learning disorder (NVLD). Each type of perceptual-motor exercise (bilateral vs. unilateral) is delivered in two different ways. Within each method, free-play and non-interventional activities are scheduled at different times (e.g., at the beginning vs. the end of the intervention phase). The main questions this study aims to address are: 1. Which type of perceptual-motor (PM) exercise-bilateral or unilateral-is more effective in improving manual dexterity of left and right hands and visuospatial memory in children with nonverbal learning disorder (NVLD)? 2. Which training sequence in unilateral and bilateral groups-free-play and self-oriented activities followed by interventional exercises, or interventional exercises followed by free-play activities-has a greater impact on right and left hands manual dexterity and visuospatial memory scores in children with NVLD?
