First, the investigators have designed and implemented a novel six week self-management training program for DLSS over the past 3 years at the Spinal Stenosis Clinic at the Rebecca MacDonald Centre for Arthritis and Auto-immune Diseases at Mount Sinai Hospital (MSH). The goal of the training program is to provide patients with the knowledge, skills, self-confidence, and physical capacity to manage their symptoms and maximize their function. The program is multi-modal, tailored and directed to the structural, functional, physiological and psychosocial consequences of DLSS. Particular emphasis is placed on exercise instruction to build core and lower extremity strength and enable individuals to achieve optimal posture during standing and walking.
