Not infrequently the lumbosacral root-compression syndrome is due to stenosis of the lumbal spinal canal. The clinical symptoms, usually emerging in the middle-aged, may be characterized by either simple radicular pain with or without neurological deficit or by exercise-dependent transient functional disturbance of the cauda equina, namely, the so-called neurogenic intermittent claudication (NIC). In most cases, NIC is due to mechanical compression of the cauda fibers as a result of extension of the patient's lumbar spine. In some patients, exercise-induced ischemic radiculopathy is assumed to be the main factor. Differential diagnosis must take into account true intermittent claudication, certain rare myopathies (if the exercise-dependent pain is the main feature), and certain transient disturbances in spinal cord function (if a motor and/or sensory deficit arises during the NIC attack).
腰骶神经根压迫综合征常常是由腰椎管狭窄引起的。临床症状通常出现在中年人身上，其特征可能是单纯的神经根性疼痛，伴有或不伴有神经功能缺损，或者是马尾神经的运动依赖性短暂功能障碍，即所谓的神经源性间歇性跛行（NIC）。在大多数情况下，NIC是由于患者腰椎伸展导致马尾神经纤维受到机械性压迫所致。在一些患者中，运动诱发的缺血性神经根病被认为是主要因素。鉴别诊断必须考虑真性间歇性跛行、某些罕见的肌病（如果运动依赖性疼痛是主要特征）以及脊髓功能的某些短暂性障碍（如果在NIC发作期间出现运动和/或感觉缺损）。
