A variety of clinical tests are used to detect a subtle upper motor neuron lesion but only a few studies have measured their sensitivity and specificity. The forearm rolling test and its variant, the finger rolling test, is one such. These tests are simple and only take 5-10 s to perform. Their sensitivity has varied in different studies but in general both are more likely to be abnormal in a patient with a focal brain lesion than abnormal power, tone and reflexes. The finger rolling test is more sensitive than forearm rolling. Furthermore, an abnormal response on testing forearm and finger rolling has a high specificity for the presence of a focal brain lesion.
多种临床测试用于检测细微的上运动神经元病变，但仅有少数研究测量过它们的敏感性和特异性。前臂滚动试验及其变体手指滚动试验就是其中之一。这些测试很简单，执行仅需5 - 10秒。它们的敏感性在不同研究中有所不同，但总体而言，与力量、肌张力和反射异常相比，局灶性脑损伤患者的这两项测试更易出现异常。手指滚动试验比前臂滚动试验更敏感。此外，前臂和手指滚动测试的异常反应对局灶性脑损伤的存在具有很高的特异性。
