Abstract
We studied the usefulness of Walking Impairment Questionnaire (WIQ) for the evaluation of intermittent claudication in lumbar spinal stenosis. The subjects consisted of 18 males and 12 females whose average age was 71. Of the 30 subjects, we operated on 12. WIQ, AWD, RDQ, and JOABPEQ scores improved significantly after treatment. As for the correlation between these scores and evaluative parameters, significant correlation was seen between pain score and VAS numbness of the lower limb only; distance score and JOA, RDQ, JOABPEQ lumbar dysfunction, AWD, PF, RP, RE of SF-36; speed score and AWD, PF, RP, RE of SF-36; and climbing score and PF, RP, GH, SF, RE of SF-36. The WIQ was found to be useful for evaluating intermittent claudication in lumbar spinal stenosis.
