There are at least two possible models depicting the relationship between buccofacial and limb apraxia. First, apraxia can be viewed as a unitary motor disorder which transcends the output modalities of both buccofacial and limb output. A high degree of similarity between the two types of apraxia would support this model. Alternatively, the relationship between buccofacial and limb apraxia may not include a unitary mechanism. The presence of quantitative and qualitative differences between buccofacial and limb performance would support this nonunitary model. The results of the present study support the nonunitary model.
至少有两种可能的模型来描述口面部失用症和肢体失用症之间的关系。首先，失用症可被视为一种单一的运动障碍，它超越了口面部和肢体输出的运动模式。两种类型的失用症之间的高度相似性将支持这一模型。或者，口面部失用症和肢体失用症之间的关系可能不包括单一机制。口面部和肢体表现之间存在数量和质量上的差异将支持这一非单一模型。本研究结果支持非单一模型。
