The model of apraxia proposed by Roy (1996) states that three patterns of apraxia should be observed across pantomime and imitation conditions. In the present analysis the frequency and severity of each pattern of apraxia were examined in a consecutive sample of left-(LHD) and right-hemisphere-damaged (RHD) patients during the production of intransitive limb gestures. The results indicated that a significant proportion of LHD and RHD patients were selectively impaired in formulating the ideational component of intransitive limb gestures.
罗伊（1996年）提出的失用症模型指出，在手势模仿和动作模仿条件下应观察到三种失用症模式。在本分析中，对左半球损伤（LHD）和右半球损伤（RHD）患者的连续样本在进行不及物肢体动作时，检查了每种失用症模式的频率和严重程度。结果表明，相当一部分LHD和RHD患者在制定不及物肢体动作的概念成分时存在选择性损伤。
