Abstract
Subjective symptom, neurological signs and skin temperature of lower limbs were examined in 20 patients with intermittent claudication of cauda equina before and after excercise test.In 15 patients (75%), increased neurological signs were observed. Straight leg raising was restricted in 5 patients, sensory deficit were increased in 12 patients and 9 patients became worser in weakness of lower limbs. These alternations tended to be provoked in agreement with lesions, so excercise test appeared to assist in level diagnosis.Many patients had cold area in the affected limb and it was suggested that the increase of cold area caused by walking correlates that of sensory deficit.
