Occupational therapists frequently work with children with developmental coordination disorder (DCD) in hopes of enhancing their occupational performance. There is debate among researchers and health care professionals about whether the motor coordination problems experienced by children with DCD have a physiological basis or whether they are the result of a developmental delay. Even among researchers who agree that these difficulties are of physiological origin, there is a lack of consensus as to whether these motor problems are multisensory or unisensory. This article focuses on the physiological explanation, presents a review of the literature on the possible physiological origins of motor coordination problems in children with DCD, and shows that the current literature on the physiological basis of DCD requires more empirical evidence to substantiate either multisensory or unisensory theories of motor dysfunction in children with DCD. The debate over the nature of motor problems in children with DCD has two implications for occupational therapists: that there is no one way to treat these children and that the cause of the difficulty varies from child to child.
职业治疗师经常与患有发育性协调障碍（DCD）的儿童合作，以期提高他们的职业表现。研究人员和医疗保健专业人员之间存在争议，即患有DCD的儿童所经历的运动协调问题是有生理基础，还是发育迟缓的结果。即使在那些认同这些困难源于生理因素的研究人员中，对于这些运动问题是多感官的还是单感官的，也缺乏共识。本文聚焦于生理学解释，综述了关于DCD儿童运动协调问题可能的生理起源的文献，并表明目前关于DCD生理基础的文献需要更多实证证据来证实DCD儿童运动功能障碍的多感官或单感官理论。关于DCD儿童运动问题本质的争论对职业治疗师有两个启示：治疗这些儿童没有单一的方法，而且困难的原因因儿童而异。
