Children diagnosed with Autism Spectrum Disorder (ASD) have difficulties with social communication and relational interactions as well as repetitive and stereotypical movements. Based on the assumption that movement synchrony can be used to enhance social skills, this study examines the synchrony of body rhythms between children with ASD and their music therapists. A computerized diagnostic for calculating body synchrony characteristics, based on the Kestenberg Movement Profile, was developed. Data collection took place over a period of 20 weeks. The participants had been recruited for a large international controlled trial study where ‘improvisational music therapy’ was used as music therapy approach. The methods in the current study included microanalysis of video footage of nineteen 4- to 6-year-old children diagnosed with ASD. The results revealed higher levels of synchrony between the therapists and children when the latter were using repetitive rhythmicity that occurred 2 or more times per second. At the end of the treatment, there was no significant change in autistic symptoms and in the children's ability to synchronize with the therapists, although the therapists were significantly more synchronize with the children. We discuss the possible role of music therapists in promoting experiences for children through the use of basic body rhythmicity patterns.

被诊断患有自闭症谱系障碍（ASD）的儿童在社交交流和关系互动以及重复性和定型运动方面存在困难。基于运动同步可以用来提高社交技能的假设，本研究研究了自闭症儿童与其音乐治疗师之间身体节律的同步性。基于Kestenberg运动曲线，开发了一种用于计算身体同步特征的计算机诊断程序。数据收集历时20周。已招募参与者参加大型国际对照试验研究，其中“即兴音乐疗法”被用作音乐疗法。本研究中的方法包括对19名诊断为ASD的4至6岁儿童的录像进行显微分析。结果表明，当治疗师和孩子使用每秒重复2次或更多次的重复节奏时，治疗师和孩子之间的同步程度更高。在治疗结束时，自闭症症状和儿童与治疗师的同步能力没有明显变化，尽管治疗师与儿童的同步性明显提高。我们讨论了音乐治疗师通过使用基本的身体节奏模式在促进儿童体验中的可能作用。尽管治疗师与孩子的同步化程度更高。我们讨论了音乐治疗师通过使用基本的身体节奏模式在促进儿童体验中的可能作用。尽管治疗师与孩子的同步化程度更高。我们讨论了音乐治疗师通过使用基本的身体节奏模式在促进儿童体验中的可能作用。
