A Biomechanical and NeuroImaging Study for Clumsiness and Developmental Coordination Disorder.

发展性协调障碍(DCD)，即所谓的“笨拙”，干扰了学习成绩和参与体育活动，以及心理社会功能的发展，如自尊、认知或情感的发展。DCD是一种常见的儿科疾病，全世界估计其患病率为6-10%。然而，在日本也有一些关于DCD的研究。在本研究中，我们对大量发育障碍患者的“笨拙”进行了详细的评估，开发了两份国际问卷(DCDQ和MOQ-T)的日语版作为筛查工具，并建立了生物力学和神经成像的方法学或临床应用，如事件相关电位、近红外光谱、PET和功能磁共振成像。

Developmental Coordination Disorder (DCD), so called "Clumsiness", interferes with academic performance and participation in physical activities and development of psychosocial functions, such as self-esteem, cognition, or emotion through the Life. DCD is a common pediatric condition and its prevalence is estimated to be 6-10%, worldwide. There are, however, a few studies of DCD in Japan. In this study, we evaluated, in detail, "Clumsiness" in the large numbers of the cases with developmental disorders, developed the Japanese versions of two international questionnaires (DCDQ and MOQ-T) as the screening instruments, and established the methodology or the clinical applications of the biomechanical and the neuroimaging, such as ERP, NIRS, PET, and fMRI.
