许多研究表明舞蹈对大脑的影响。似乎长期的练习可以调节大脑的可塑性和视觉运动技能,因为它激活了行动观察网络(AON)。这项系统评价的目的是评估专业舞者和非舞者成年人之间大脑活动(视觉运动技能)的潜在差异,通过脑电图(EEG)测量,在观察正在跳舞的个体(视频舞蹈刺激)期间。根据PRISMA指南,此次文献检索于2022年2月至6月进行,在PubMed数据库中使用高级搜索,网格项,和广泛的手动搜索。所包含的文章以英文发表。具体来说,选择了病例对照研究,使用健康的成年人,专业舞者,和非舞者作为参与者,他们暴露于视频舞蹈片段并通过脑电图进行测量。如果这些文章是基于不同类型的研究,不健康的人群,有运动背景的对照组,不同类型的刺激(有节奏的),或不同类型的任务和程序。使用JoannaBriggs研究所(JBI)的关键评估工具对证据质量进行评估。纳入5项病例对照研究,共有193名参与者,87%的女性。参与的专业舞者组(n=12-25)的平均年龄为25.14岁,经过至少9-19年的专业培训,而对照组的样本量相同,平均年龄24.14岁,也没有跳舞的经验.大多数研究都具有较高的方法学质量。所有研究都显示舞者的大脑活动存在显著差异,特别是关于视觉运动技能。结果表明,在额中央区域较高的P300表明AON的激活更快,并且枕骨颞叶皮层的敏感性增加。舞者可以更轻松地应对熟悉而不熟悉且毫不费力的动作。他们还展示了更快的α波段峰值频率,在θ波段上有更强的同步性,beta,在视听刺激期间的伽马,以及更快地编码视觉信息的能力。结果表明,舞者具有更好的视觉运动技能,表明舞蹈增强了神经可塑性,因为专业舞者更容易处理他们的动作。跳舞,其中包括视觉运动任务,可以帮助预防,治疗,和神经退行性疾病或运动障碍的康复。
Many studies have shown the effect of dance to the brain. It seems that long-term practice modulates brain plasticity and visuomotor skills, as it activates the Action Observation Network (AON). The aim of this systematic review was to evaluate potential differences in the brain activity (visuomotor skills) between professional dancers and non-dancer adults, measured by electroencephalography (EEG), during the observation of an individual who is dancing (video dance stimuli). This literature search was conducted from February to June 2022, according to the PRISMA guidelines, in the PubMed database using advanced search, mesh terms, and extensive manual search. The included articles were published in English. Specifically, case-control studies were selected, which used healthy adults, professional dancers, and non-dancers as participants, who were exposed to video dance clips and measured by EEG. The articles were excluded if they were based on different type of study, unhealthy population, control group with athletic background, different type of stimuli (rhythmic), or different type of task and procedure. The ratings of quality of evidence were conducted using the Joanna Briggs Institute\'s (JBI) critical appraisal tool. Five case-control studies were included with 193 participants in total, 87% females. The participating groups of professional dancers (n = 12-25) had mean age 25.14 years, with at least 9-19 years of professional training, whereas control groups had the same sample size, mean age of 24.14 years, and no experience in dancing. Most of the studies presented high methodological quality. All studies showed significant differences in dancers\' brain activity, especially regarding the visuomotor skills. The results showed faster activation of AON demonstrated by higher P300 at the frontocentral regions and increased sensitivity of the occipital temporal cortex. Dancers could cope easier with familiar-unfamiliar and effortful-effortless movements. They also demonstrated faster alpha band peak frequency, stronger synchrony over the bands theta, beta, gamma during the audiovisual stimuli, and the ability to encode faster the visual information. The results demonstrate that dancers had better visuomotor skills suggesting dance-enhanced neuroplasticity, as professional dancers processed their actions easier. Dance, which includes visuomotor tasks, could help in prevention, therapy, and rehabilitation of neurodegenerative diseases or movement disorders.
