The examination of sacral reflexes provides an important method to differentiate an upper motor neuron vs lower motor neuron spinal cord injury (SCI). Two common sacral mediated reflexes used as part of the neurological assessment include the bulbocavernosus reflex (BCR) and anal reflex. As the clinical information from these tests are similar, we suggest that the anal reflex provides a better first option as a non-invasive clinical assessment of sacral reflex status in clinical practice in SCI as the testing for the anal reflex is less intrusive and already being performed as part of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) by pinprick stimulation of the S4-5 dermatome.

肛门反射与球海绵体肌反射在脊髓损伤患者评估中的比较。

骶反射检查提供了区分上运动神经元与下运动神经元脊髓损伤（SCI）的重要方法。作为神经学评估一部分的两种常见的骶介导反射包括球海绵体肌反射 (BCR) 和肛门反射。由于这些测试的临床信息相似，我们建议肛门反射作为 SCI 临床实践中骶反射状态的非侵入性临床评估提供更好的首选，因为肛门反射测试侵入性较小，并且已经被广泛应用。作为脊髓损伤神经学分类国际标准 (ISNCSCI) 的一部分，通过 S4-5 皮刀的针刺刺激进行。
