Lower @entity158 caused by exercise but relieved by rest is usually a reliable symptom of chronic @entity9085 . However, similar discomfort often occurs in @entity1 who have neurospinal compression. Furthermore, both @entity432 and neurogenic causes of lower extremity discomfort may present simultaneously. Forty @entity1 with symptoms that suggested intermittent @entity613 comprised our study group. All had non-arterial cause of their complaint. The nonvascular origin of the symptoms was suggested initially by clinical evaluation in 30 @entity1 and by noninvasive evaluation in 25 @entity1 . The neurospinal origin of symptoms was obscured in 15 @entity1 because of the concomitant presence of significant @entity432 as demonstrated by noninvasive arterial testing. Twelve of these 15 @entity1 underwent arterial reconstruction, which did not relieve their symptoms. Subsequently, the neurospinal origin of their symptoms was proven by appropriate evaluation and therapy. Forms of evaluation that proved helpful in the differential diagnosis were lumbosacral spine x-rays, electromyography, nerve conduction velocity studies, computerized tomography, Doppler noninvasive assessment and, at times arteriography and contrast myelography.
