为了阐明间歇性跛行的病理生理学，在37例腰椎管狭窄症患者中，通过检查步行应激前后的体感诱发电位（stress-SEP）和神经动作电位（stress-NAP）来评估神经功能。37例患者中有31例术前显示行走后应激性SEPs立即异常。在9名手术患者中的7名中，评估清楚地显示SEP在手术后恢复正常。本方法无创、技术简单、无痛、安全，是诊断和治疗腰椎管狭窄症的第一步。它也可能有助于区分神经源性和血管性间歇性跛行。
To clarify the pathophyslology of intermittent claudication In 37 patients with lumbar spinal stenosis, neural function was evaluated by examining somatosensory evoked potentials (stress-SEPs), and nerve action potentials (stress-NAPs) before and after walking stress. It was shown preoperatively that the stress-SEPs became abnormal Immediately after walking In 31 of 37 patients. In seven of nine operated patients, the assessment clearly shows that SEPs had reverted to normal after surgery. The present method Is nonlnvaslve, simple In technique, painless, and safe, a procedure therefore that is useful as the Initial step in the diagnosis and treatment of patients with lumbar canal stenosis. It also may help to differentiate neurogenic from vascular intermittent claudication.
