Retrospective review.
The International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) assesses cutaneous sensibility through light touch (LT) and sharp-dull discrimination, referred to as pin prick (PP). This project aimed to confirm a tendency for LT to score higher than PP in SCI subjects and discuss possible reasons for such disparity.
Single site cohort study, the London Spinal Cord Injury Centre, United Kingdom.
A retrospective analysis of LT and PP scores of 99 spinal cord injury subjects at the time of discharge (median 5 months) from acute care and rehabilitation in the London Spinal Cord Injury Centre was conducted. Subjects were aged 10-88 years (median 44 years; 78 men, 74 traumatic, 25 non-traumatic). There were 40 American Spinal Injury Association (ASIA) Impairment Scale (AIS) A, 7 B, 18 C and 34 D subjects.
A disparity (P<0.001) was found between LT (64.5±3.2, mean±s.e.) and PP (54.7±2.9) AIS sensory scores. A similar difference in score (LT>PP) was registered both for traumatic and non-traumatic injury, but was greater for incomplete than for complete injury. Despite the difference, LT was well correlated with PP (R=0.87, P<0.001). Spinal segmental level of injury was determined more frequently by PP alone (43 of 99) than by LT (10 of 99) alone.
The discrepancies between LT and PP could relate to the greater complexity of the PP test or a difference in the extent of injury to the posterior columns (LT) and spinothalamic (PP) tracts. Further interpretation would benefit from additional electrophysiological sensory tests.
回顾性研究。
国际脊髓损伤神经分类标准（ISNCSCI）通过轻触（LT）和锐钝觉辨别评估皮肤感觉，后者称为针刺觉（PP）。本项目旨在证实 SCI 患者的 LT 评分高于 PP 的趋势，并讨论这种差异的可能原因。
英国伦敦脊髓损伤中心的单站点队列研究。
对 99 例脊髓损伤患者在急性护理和康复出院时（中位数为 5 个月）的 LT 和 PP 评分进行回顾性分析。受试者年龄为 10-88 岁（中位数为 44 岁；78 名男性，74 例创伤性，25 例非创伤性）。美国脊髓损伤协会（ASIA）损伤量表（AIS）有 40 例 A 级、7 例 B 级、18 例 C 级和 34 例 D 级患者。
发现 LT（64.5±3.2，均值±s.e.）和 PP（54.7±2.9）AIS 感觉评分之间存在显著差异（P<0.001）。创伤性和非创伤性损伤的评分差异（LT>PP）相似，但不完全性损伤的差异大于完全性损伤。尽管存在差异，但 LT 与 PP 高度相关（R=0.87，P<0.001）。损伤的脊髓节段水平更常通过 PP 单独确定（99 例中有 43 例），而不是 LT 单独确定（99 例中有 10 例）。
LT 和 PP 之间的差异可能与 PP 测试的复杂性更大或后柱（LT）和脊髓丘脑（PP）束损伤程度的差异有关。进一步的解释将受益于额外的电生理感觉测试。
