Pathological limb pain patients show decreased attention to some stimuli on the painful limb and increased attention to others, a paradox that has dogged the field for over a decade. We hypothesized that pathological pain involves a spatial inattention confined to bodily representations. Patients showed inattention to the painful side for visual processing of body parts but not letters, tactile processing but not auditory, and body-part bisection tasks but not line bisection tasks. We propose the new term "somatospatial inattention" to describe bodily-specific spatial inattention associated with pathological limb pain.
病理性肢体疼痛患者对疼痛肢体上的某些刺激的注意力降低，而对其他刺激的注意力增加，这种自相矛盾的现象已经困扰该领域十多年了。我们假设病理性疼痛涉及到一种局限于身体表象的空间注意力不集中。患者在视觉处理身体部位时对疼痛侧表现出注意力不集中，但在处理字母时则不会，在触觉处理时不会，在身体部位二分任务时不会，但在线条二分任务时会。我们提出了一个新的术语“躯体空间性注意力不集中”来描述与病理性肢体疼痛相关的躯体特异性空间注意力不集中。
