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.
许多研究表明了舞蹈对大脑的影响。长期练习似乎可以调节大脑可塑性和视觉运动技能，因为它会激活动作观察网络（AON）。本系统评价的目的是评估专业舞者与非舞者成年人在观察他人跳舞（视频舞蹈刺激）期间，通过脑电图（EEG）测量的大脑活动（视觉运动技能）的潜在差异。根据PRISMA指南，于2022年2月至6月在PubMed数据库中使用高级搜索、主题词和广泛的手动搜索进行了文献检索。纳入的文章以英文发表。具体而言，选择了病例对照研究，其使用健康成年人、专业舞者和非舞者作为参与者，让他们观看视频舞蹈片段并通过EEG进行测量。如果文章基于不同类型的研究、不健康人群、有运动背景的对照组、不同类型的刺激（节奏性）或不同类型的任务和程序，则将其排除。使用乔安娜·布里格斯研究所（JBI）的批判性评价工具对证据质量进行评级。纳入了五项病例对照研究，共有193名参与者，其中87%为女性。专业舞者参与组（n = 12 - 25）的平均年龄为25.14岁，至少有9 - 19年的专业训练，而对照组的样本量相同，平均年龄为24.14岁，且无舞蹈经验。大多数研究呈现出较高的方法学质量。所有研究均显示舞者的大脑活动存在显著差异，尤其是在视觉运动技能方面。结果显示，额中央区域的P300越高，表明AON的激活越快，枕颞叶皮质的敏感性增加。舞者能够更轻松地应对熟悉 - 不熟悉以及费力 - 不费力的动作。他们还表现出更快的α波段峰值频率，在视听刺激期间，θ、β、γ波段的同步性更强，并且能够更快地编码视觉信息。结果表明，舞者具有更好的视觉运动技能，这表明舞蹈增强了神经可塑性，因为专业舞者处理动作更容易。包括视觉运动任务的舞蹈有助于神经退行性疾病或运动障碍的预防、治疗和康复。
