Abstract

Background: The aim of this study was to analyze the gamma-band frequency and motor performance of children with and without music training.

Methods: This cross-sectional study included 31 right-handed children, 6–11 years old, who were allocated to two groups: 1) the music group (MG), including children who attended preschool and musical training (n = 16), and 2) the no-music group (NMG), including children who attended preschool but received no additional music training (n = 15). The outcomes were gamma-band frequency measured by electroencephalography, manual dexterity, aim-and-catch, and static and dynamic balance abilities measured by the Movement Assessment Battery for Children, and fine motor skills, overall motor skills, balance, corporal body scheme, spatial organization, temporal orientation, and general motor quotient (GMQ) by a Brazilian scale for motor development.

Results: There 1was a significant difference between groups in the peak frequency (p = 0.0195) and median frequency (p = 0.0070) in the F3–F4 regions. Static and dynamic balance (p = 0.03), temporal orientation (p < 0.01), and GMQ (p < 0.03) were higher in MG than in NMG.

Conclusion: The musically trained children had increased gamma-peak frequency in the frontal region and greater temporal orientation, balance, and the overall motor quotient.

摘要

背景：本研究的目的是分析接受和不接受音乐训练的儿童的伽马波段频率和运动表现。

方法：这项横断面研究包括 31 名 6-11 岁的右利手儿童，他们被分配到两组：1）音乐组（MG），包括参加学前班和音乐培训的儿童（n = 16）， 2) 无音乐组 (NMG)，包括上过学前班但未接受额外音乐训练的儿童 (n = 15)。结果是通过脑电图测量的伽马波段频率、手动灵巧度、瞄准和捕捉以及通过儿童运动评估电池测量的静态和动态平衡能力，以及精细运动技能、整体运动技能、平衡、身体计划，巴西运动发展规模的空间组织、时间方向和一般运动商 (GMQ)。

结果：  F3-F4区域的峰值频率（ p  = 0.0195）和中值频率（p = 0.0070）组间存在显着差异。MG 的静态和动态平衡 ( p  = 0.03)、时间方向 ( p  < 0.01) 和 GMQ ( p  < 0.03) 高于 NMG。

结论：受过音乐训练的儿童在额叶区域的伽马峰频率增加，时间定向、平衡和整体运动商数更高。
