Lumbar spinal stenosis (LSS) is one of the most common affecting the elderly population that may lead to loss of function and the inability to execute basic activities of daily living. While surgical decompression remains the standard of care, choosing an optimal management strategy is usually guided by a set of clinical, radiological, and measurement indices. However, to date, there is a major uncertainty and discrepancy regarding the methodology used. There is also inconsistent adoption of outcome measures across studies, which may result in huge limitations in predicting the efficacy and cost-effectiveness of different treatment paradigms. Herein, we review the various measurement indices used for outcome assessment among patients with LSS, and delineate the major advantages and disadvantages of each index. We call for the development of a single objective outcome measure that encompasses and addresses all issues encountered in this heterogeneous group of patients, including monitoring the patient's progression after treatment.
