OBJECTIVES AND HYPOTHESES The overall goal of this study is to assess the effectiveness of four self-management strategies in improving walking ability among patients with DLSS. The investigators primary objective is to compare the effectiveness of a comprehensive six week self-management training program that includes a patient instructional workbook, video and pedometer to a patient workbook, video and pedometer alone. The investigators secondary objectives are: 1) to compare the change in walking capacity from baseline when using superficially applied para-spinal TENS versus placebo para-spinal TENS applied during walking and 2) to compare the change in walking capacity from baseline while wearing a novel spinal stenosis belt to the use of a sham spinal stenosis belt while walking. The investigators hypothesize that the self-management training program with workbook, video and pedometer will be more effective in improving walking capacity and functional outcomes than the use of a workbook, video and pedometer alone. Furthermore, the investigators hypothesize that para-spinal TENS or the novel spinal stenosis belt used while walking will be more effective in improving walking capacity than placebo TENS or a sham spinal stenosis belt, respectively.
